Exploring the Applicability of Benford's Law in Network Science and Graph Theory

Benford’s law, also known as the law of the first digits, shows that the first digits of numbers in a series of records from various sources are not uniformly distributed, but follow a decreasing order of occurrence from “1” to “9”. It is commonly used to detect anomalies in data series and can also raise suspicions of fraud. In this paper, the applicability of Benford’s law to different types of networks is studied. The study analyses ten real networks of different sizes and three theoretical network models, examining the degree centrality, the betweenness centrality and the closeness centrality distributions of each network. The results indicate that only the betweenness centrality distributions of real networks follow Benford's law. The study suggests that differences in significant number distributions may be due to internal properties of networks, requiring further analysis to identify necessary and sufficient conditions and assumptions for applying Benford’s law. Overall, the study highlights the potential of using Benford’s law in network analysis to identify properties and potential anomalies in real-world applications.

Evaluation of Genetic Algorithm on the Multidrop Truck-Drone Logistic Problem

This paper explores the use of genetic algorithms (GA) to optimize the route and schedule planning for multi-trip last-mile delivery operations using a fleet of trucks and drones. The research builds upon the work of (Murray and Chu, 2015) who proposed the use of truck-drone teams. The authors suggest that GA is a flexible procedure for defining the routing plan for urban last-mile delivery applications, capable of searching through a large search space to reach high-quality solutions. The authors conduct a literature review of twenty papers that use GA to solve the truck-drone delivery problem and identify two interesting approaches. They present the specifics of their coding structure and describe their GA framework for addressing the targeted problem. The findings demonstrate that the proposed GA approach outperforms other frequently employed optimization methods. The authors conclude that GA provides a powerful tool for decision-makers to optimize multi-destination last-mile delivery operations.

Sustainable Last Mile in e-Commerce: Identifying Innovative Solutions

The interest in last mile, considered the most important factor in e-commerce, has grown as online sales have increased. This interest has been reflected in the literature, which has sought to analyze and quantify new sustainable strategies. However, some of these solutions have only been implemented in specific cases with a limited geographical scope. The purpose of this article is to provide a comprehensive analysis of retailers’ perspectives on sustainability and to identify which sustainable innovations retailers are implementing in their last-mile strategies. To achieve this, an exploratory study based on 15 semi-structured interviews with e-retailers was carried out. As a result, 12 innovative solutions were identified. These include the redesign of vehicle fleets, the design of routes based on demand density or the use of collection points for reverse logistics, among others.

Order Promising Process Optimization for Hybrid Production Strategy

The increased customization of products obliges many companies to adopt hybrid production strategy (HPS) combining make-to-stock (MTS) and make-to-order (MTO) products. Research for the order promising process in HPS is very scarce. This paper proposes a novel MILP model to support the process of committing orders including MTO and MTS products. With scarce availability of resources, companies may be interested in accepting only order proposals ensuring a minimum profit. For that, the model checks and synchronize three levels of availability to promise both type of MTS and MTO products: ATP (Available-To-Promise), CTP (Capable-To-Promise) and PTP (Profitable-To-Promise). The model validation demonstrates its usefulness in environments with tight supply and shortages.

Comparative Analysis of Cost Structures and Factors of Conveyor Technologies for In-Plant Production Supply

In recent years, there has been a rapid development in the field of conveyor techniques concerning constructive design, algorithms and price drop. Current planning procedures fall short as they are limited to dimensioning calculations and do not include system comparisons. This paper provides support for the planning and reorganization on the basis of a dimensioning and evaluation model. For a defined use case, sensitivity analyses are performed for six input variables and three different conveying techniques. From the results, a cost comparison of the conveying techniques is made and the input variables are ranked in terms of their cost influence. The comparative analyses support the system selection in an early planning phase, the ranking provides promising starting points for the reorganization of existing systems.

News and ESG Investment Criteria What’s Behind It?

News written in the press about companies generates consumer feelings that can condition the reputation of these companies and, consequently, their financial results. One of the practices that might improve the reputation of a company are the Environmental, Social and Governance (ESG) investment criteria. In this research, we have used Natural Language Processing techniques to identify those ESG-related terms that the press use for companies, in order to detect and analyze which terms improve sympathy towards companies and which worsen it. Finding that those terms related to sustainable development improve it and those related to greenwashing worsen it. With this information, companies can take measures to improve their image, their reputation, and their financial results.

Measuring Transport Performance: A Case Study in an Agrifood Retail Company

Road freight transport plays a key role in the economy and its optimisation becomes a priority. Preceding efficiency improvements, a first stage of performance measurement based on Key Performance Indicators (KPIs) seems necessary. A case study was carried out in an agrifood retail company using the Action Research methodology. The firm worked with transport KPIs not reflecting reality. Therefore, the aim of the study is to define a set of KPIs based on available information and experts’ opinions. Indicators were established in 5 key areas: schedules, temperatures, complaints, occupancy and productivity. A dynamic dashboard is proposed with different visualisations depending on the audience. Staff were trained and involved in the process while a follow-up procedure was applied based on regular multidepartmental meetings. This publication suggests a guide for the implementation of a performance measurement system, identifying weak points and providing best practices and recommendations for successful replication. In addition, the case study demonstrates how a correct KPIs selection and management could enhance effective decision-making and emerge continuous improvement.

Big Data and E-Commerce: Future Key Players for the Urban Last Mile Management

The set of tools that constitute the Big Data (BD) concept has been used, since its origin, in various fields of knowledge with special emphasis on the marketing area of organisations. The main objective of its use is to improve the customer experience, in a way that is more in line with the customer's tastes, rigorously adapting the needs of the products and services offered. On the other hand, E-Commerce, as an omni-channel business model, could not be as efficient and profitable if the delivery of goods in the Last Mile Delivery (LMD) as the final link in the supply chains had not been developed in the same way. This document presents a summary of the trends, uses, and fields that, in the context of the LMD, are being worked on within BD and E-Commerce.

Exploring Internet of Things (IoT) Adoption: Drivers, Enablers and Barriers

In each industry of the different economic sectors, the integration of digital technologies continues unabated. Many companies are digitizing their products and processes, integrating technologies among which the Internet of Things (IoT) stands out, due to its role of collecting, processing, deciding, and triggering actions between objects. However, the adoption of IoT implies the complex management of factors, among which some drive and motivate (drivers), others enable conditions (enablers), and others arise as obstacles that hinder implementation (barriers). This document focuses on a review of the literature on the drivers, enablers, and barriers for IoT adoption, placing special emphasis on companies in the primary sector of the economy. As goal, this review seeks to identify these factors in the adoption of IoT, and to identify the most common and least influential ones.

Car Parking Spaces for Logistics Activities. Is this an Interesting Alternative for City Logistics Companies?

Urban consolidation centres can reduce the negative impact of last-mile delivery in cities. However, from the different case studies documented, it is clear that their economic sustainability is difficult to achieve. The recent change in the policy of Barcelona municipality to allow logistics activities in underground car parks opens up the possibility of using these spaces as urban consolidation centres (UCCs) or transhipment zones. The aim of this study is to assess whether the use of these new logistics spaces is beneficial for logistics companies. This analysis has been done considering data from the city of Barcelona.

Investment Strategy to Properly Maintain Water Networks

This article focuses on the problem of deciding the annual investment that a company should allocate to the rehabilitation of its water distribution and sanitation networks. The objective is to find the investment amount necessary to maintain an adequate quality and sustainability of the infrastructure. It is not a simple decision, as there are different criteria that may be of interest to the managing company. In this paper, we consider four criteria related to the reliability of individual pipes and the complete network. These indicators are the infrastructure value index, the average age of network pipes, the risk index and the probability of failure. A methodology is proposed to estimate the best annual investment by analysing the evolution of these indicators.

Electricity Distribution Among Users of an Energy Community: Calculation of Repartition Coefficients Under Social Scenarios

Current Spanish regulation allows the calculation of repartition coefficients to distribute electricity to users of an energy community. Literature has focused on minimum-cost solutions, and has paid less attention to the introduction of social objectives (e.g., equity) and constraints (e.g., due to the presence of users in a vulnerable situation). This paper studies the definition of dynamic repartition coefficients under different social scenarios by means of a mixed-integer linear programming model. Results for an illustrative case study show how the same cost per energy unit for all users can be obtained, to promote equity, or how a reduced price can be achieved for vulnerable users. Such results can assist energy communities’ promoters with the definition of the every-day electricity sharing among users.

Assessment Model of Industry 5.0 Implementation in Small and Medium-Sized Companies in the Metal Sector, Using AHP and Fuzzy Inference Systems

The European Commission published its Industry 5.0 agenda in 2021, giving guidelines for a resilient, sustainable and human-centric European Industry. This study proposes a framework to analyze this concept by linking industrial, human-centric and sustainability objectives, driven by a new wave of disruptive technologies. This model assesses the degree of Implementation of Industry 5.0 (I5.0) in 3 Small and Medium Enterprises (SMEs) in the Metal sector of the Principality of Asturias. A conceptual model has been developed that identifies the factors that must be taken into account in the implementation of I5.0 by SMEs through a literature review and consultations with a group of experts in the field. The methodology employed uses, firstly, the Analytical Hierarchical Process (AHP), and secondly, a Fuzzy Inference System (FIS) to infer the degree of implementation of any SME in the I5.0 environment. The work focuses on the study of the “Human Factor” dimension of the model designed, showing that the “employee well-being” factor is the most relevant, followed by the “acquisition of skills and competences” and lastly by “Human-Machine Interaction”. Likewise, after designing the FIS, we proceeded to establish the positioning and ranking of a pilot sample of SMEs in the metal sector.

Bridging the University-Business Gap in Engineering Schools: Implementation of a Course Groupwork in Innovation Management

The gap between university and business has been mentioned recently as one of the most serious problems in Engineering schools. In this study, we propose a groupwork methodology to help bridge this gap, by allowing students to interact with start-ups, study their strategies, and apply this knowledge on a practical project. Students were asked to visit a start-up and describe its business model. Afterwards, they developed an innovative idea for a product or service, and designed a business model to exploit this idea, using the knowledge acquired in the first stage. Results were very satisfactory, with higher engagement and overall student satisfaction with the course.

Marketing On-Line OPEX as CAPEX

Marketing-online spendings capitalization led to customer acquisition is focused on demonstrating with this paper that it is controllable and has a quantifiable future benefit. In that case it must be capitalized over an increase in the value of the company (Enterprise value – EV). It will be demonstrated that there is enough data to establish that spendings on online paid advertising (SEM for Google, or Facebook Ads.) can be treated as an investment that generates a quantifiable future benefit and therefore can be activated. In this sense, it must be treated within international standards and therefore in the Spanish National General Accounting Plan of 2007, which would require an important and urgent revision, and in whose last revision of 2022, not yet taken into consideration. The research group will use a specific case study to demonstrate that an investment made for the growth and sales of a company generates a controllable, identifiable future benefit that maximizes its assets. This case study will be carried out through a cohort analysis.

Censored Exponential Smoothing for Supply Chain Forecasting

Inventory management is essential for economic success of companies since it represents a significant part of their financial balance. Stockouts represent one of the major issues that inventory management has to deal with. In case that enough stock is not available to meet demand, sales are typically a downward biased measurement of demand. Censored modelling is then necessary to forecast true demand, while the only information available are sales data. This paper develops an Exponential Smoothing forecasting model in a state space framework for censored data, so usual in supply chain contexts. The examples show how relevant this issue is and how the same inventory policy produces an important reduction in lost sales when an appropriate model including censorship is taken into account.

The Design of The Balanced Scorecard In Healthcare: A Scoping Review

Nowadays, the healthcare sector is moving to a new management model more oriented to patients, which obliges to promote coordination between the different healthcare services. This shift implies a change in their Balanced Scorecard (BSC) in order to measure future outcomes on patient health and well-being. The purpose of this research is to identify the methodologies used to build a BSC for healthcare organizations and analyse its suitability to measure and monitoring the management objectives. The study was conducted by a scoping review of the literature from 2013 to 2022 in healthcare organizations. From this research we conclude that none of the reference models identified allow measure the holistic purpose of healthcare organizations. Hence, further research is needed to propose a model adapted to the new management model of the healthcare organizations.

Industrial Energy Cluster Optimization Using Flexibility Aggregation

Individual industries can reduce their energy related costs by stipulating collaborative arrangements in the form of industrial energy communities. This paper analyses a case study of two manufacturing factories constituting an industrial energy community, presenting an approach to minimize grid electricity purchase through the aggregation of their flexibilities. The economic impact of deviating from the baseline production schedule is addressed, taking into account the additional costs of the flexibility offers. The problem is formulated as a mixed-integer linear optimization model, considering the effects of a solar PV power plant and electricity purchase on the day-ahead market. The results of the study show that the proposed approach can significantly reduce the costs of electricity purchase for the factories while maintaining the same level of production, promoting RES penetration and energy security of the cluster.

The Impact of Digitalization on Production Management Practices: A Multiple Case Study

With the diffusion of Industry 4.0, manufacturing firms can decentralize their operational decisions and enable real-time data-driven decision-making. Using a socio-technical approach and the manufacturing shop-floor as a unit of analysis, this article studies the changes induced by digitalization on operational decision-making, organizational structures, and individual competencies. A cross-country multiple case study conducted in the automotive sector suggests three main areas on which firms have to focus: decentralized data-driven decision-making, front-line managers’ upskilling, and production workers’ involvement. The successful implementation of digitalization and the actual decentralization of decision-making depend on individual factors related to the competencies of front-line managers, who acquire a central role in this skill-biased technological and organizational change.

The Impact of Electricity Tariffs on Optimal Production Scheduling

Energy costs can represent a large portion of the total production costs, and therefore, any changes in electricity tariffs can have a significant impact on profitability. This paper analyses how different types of electricity tariffs can affect the scheduling of a case study model, in particular, how time-of-use tariffs and real-time-pricing tariffs affect the single-machine scheduling problem of a production process with the introduction of the energy vector in the optimization cost. The influence of tariffs is examined, and their impact on optimal production scheduling is evaluated from an approach in demand response price-based programs, for ensuring cost-effectiveness while looking at the carbon footprint of the industrial process. The results indicate that the cost improvement of one tariff over the other is not consistent across all time periods. Meanwhile, the carbon footprint is reduced with a real-time-pricing tariff, since the real-time-pricing mechanism and the generation mix of fossil fuel technologies are positively correlated.

Trends in Unsupervised Methodologies for Optimal K-Value Selection in Clustering Algorithms

Clustering algorithms are a powerful machine learning tool when working with large datasets, as they allow data to be grouped according to certain characteristics without the need to manually label the data. These algorithms generally request the number of clusters to be formed (k) as a parameter of the model and, while in some instances it is possible to indicate this number manually, most situations require this estimation to be an unsupervised task. The most widespread techniques offer acceptable results, but there is still much room for improvement. This study highlights their main shortcomings and reviews some of the advances in the estimation of this parameter presented in recent years, exploring their advantages and limitations.

Please Don’t Go! Talent Retention Practices in IT SMEs

Companies of many kinds devote considerable resources to attracting, retaining, and developing Talent, and Small and Medium-sized Enterprises (SMEs) are no exception. Existing literature mainly focuses on Talent Management (TM) in Multinational Enterprises (MNEs) and covers very little about the additional challenges SMEs find. Talent shortages are even more relevant for companies in the Information Technology (IT) services sector. This research tries to fill the existing gap in the literature by identifying Talent Retention practices performed by a cohort of Spanish IT SMEs. Considering the Research Question ‘What are the Talent Retention Practices of Spanish IT SMEs?’, we have conducted inductive research based on semi-structured interviews, and identified seven primary practices that have proven successful, which are discussed in detail.

Genetic Algorithm to Create Bulk Delivery Routes for Multi-compartment Vehicles with Limited Capacities

The route-calculation problem for multi-compartment vehicles with limited capacities (known as the multi-compartment vehicle route problem or MCVRP) has been studied many times. In the animal feed industry, this problem has specific complicating features that require more elaborate techniques than those published in the literature. More specifically, the problem of possible incompatibilities between feeds for different animal species and the access restrictions for delivery vehicles to certain farms depending on previously undertaken routes, complicate the problem significantly. This paper presents work carried out to develop a genetic algorithm to solve this problem in a reasonable time, for application in a company that performs a very large number of daily deliveries. This algorithm can solve a more complicated problem than those present in the literature.

A Cuckoo Search Heuristic to Improve a Last Mile Ecommerce Problem

The rise of e-commerce as an alternative to face-to-face trader has entailed an increase in logistic complexity of the deliveries to end customers. It is in these deliveries that there are too many incidences due to the recipients not being in the agreed place. This work presents a new framework of last mile logistics where customers can suggest several delivery points with different time-windows. This logistics problem is a new kind of vehicle routing problem with time-windows, but more complex. A cuckoo search heuristic has been proposed to solve it. The results reveal that this new policy with several locations can reduce delivery costs. Regarding cuckoo search, this algorithm finds good solutions, as long as the execution time is not a limitation.

Quantitative Procedure for the Redesign of a Multiple Supply Chains Based on Synergies

The supply chain reconfiguration is each time more necessary due to the constant changes in the businesses. More than individual supply chains, nowadays networks appear as the addition of supply chains, with similarities between them. These chains contain different integration drivers, which are called synergistic factors. A procedure to select a configuration for a set of multi-business synergistic chains is developed in this multicriteria problem. Based on a simulation, TOPSIS with AHP is applied to determine the most synergistic and efficient configuration within a set of network alternatives. The pharmaceutical distribution for three kinds of client is used to validate it.

Enhancing Machinery Design by Using Artificial Intelligence

This paper examines the significance of Industry 4.0 and artificial intelligence (AI) in the manufacturing sector, particularly by emphasising the role of design phase in the machinery life cycle. The design phase of a machine is a complex task that requires an advanced engineering and physics knowledge level. Nevertheless in the technology era, computer-aided design tools facilitate the design task. The area of data execution and simulation of machine behaviour in different scenarios is being researched and exploited by technologies, such as the Internet of Things (IoT) or AI. With this paper, three AI-based tools are proposed and conceptualised to support AI-assisted optimisation to generate design proposals to manufacture industrial equipment, structural components, mechanisms and control components.

Including Gender Dimension in the Contents of Operations Management Teaching

Laws are increasingly demanding universities to include the gender dimension in teaching and curricula, as a part of a wider strategy that seeks to make a step forward towards real gender equality. Many universities have started to work on it the last years, normally as a part of their Gender Equality Plans. Despite the efforts made for offering and disseminating tools and guidelines, the reality is that few people know how to include the gender dimension in their teaching; the majority are not aware or are convinced that this is not possible in their courses, especially in subjects belonging to the science, technology, engineering and maths field. In this paper we propose some examples for the operations management field that, together with the existing guides and tools, can help unexperienced people to start the inclusion of the gender dimension in their teaching.

Carbon Footprint Savings from Free Fare Public Transport Policies. The Case of Marbella

One of the main goals of free fare public transport policy is to reduce car use by promoting other more sustainable modes of transport. The aim of this work is to develop a methodology that allows us to evaluate the carbon footprint savings derived from the implementation of these policies based on the CO2 emissions avoided by the trips captured from the car mode. To do this, we will study the case of the city of Marbella, comparing the evolution of the demand for bus trips, before and after COVID-19, with other cities that do not have free public transport. As a result, a total saving of 835.75 tons of CO2 emissions to the atmosphere is estimated for the study period 2019–2022. This methodology is a useful tool to measure the effectiveness of these policies in terms of environmental impact.

Is the Impact of Management Research Predictable Through the Title? - A BERT Model to Find a Response

In academia, the impact a research paper can generate is a matter of concern to most researchers. Therefore, in this study a model is proposed to evaluate whether the impact is predictive by considering the title of the article. To measure this impact, the number of times an article is cited is taken into account. In addition, the aim is to create a tool that, when a new article title is introduced, will go through the designed model and output the impact it will have in five years’ time. This paper focuses specifically on the management research field, so a dataset has been created with data downloaded belonging to this specific domain. This dataset has been labeled, preprocessed, tokenized, padded, masked and split into training and validation sets. The data were then trained and evaluated across a BERT model. The F1-score performance metric achieved is 0.56. Finally, some possible improvements are proposed.

Foundation Models-Based Artificial Intelligence in Universities: Alternative Approaches and Application Areas

Higher Education stakeholders, particularly academic institutions and faculty members, face a difficult and consequential choice regarding their approach to Foundation Models-based Artificial Intelligence. Initial reactions to the challenges it poses to long-standing academic traditions (“the death of the essay”) are often of a “contain/reject/forbid” nature. There are, however, sound arguments advocating for a more nuanced approach, combining preventive measures where appropriate with gradual and cautious embrace of its undeniable potential in nearly all facets of Higher Education.

The Smart Resilience Adviser, an Anticipation Tool Powered by Artificial Intelligence

Disruptive events keep happening; while the business world has not fully recovered from the pandemic and is still dealing with the Russia – Ukraine war, two U.S. banks were recently intervened due to financial troubles. International news mentions a potential financial recession and a potential mid-term crisis. These latent events would affect most organisations, so they need to be more resilient to face up to this turbulent context. One of the main constituent capacities of resilience is anticipation. In this work, this is assessed through a developed web tool that monitors keywords in international news sources, analyses the sentiment of each news based on artificial intelligence, guides preventive actions through access to technical articles, and offers the option to ask a smart chatbot about the manner. The guidance provided through this tool would strengthen the organizations’ anticipation capabilities and enhance enterprise and supply chain resilience.

Dimensions and Challenges to Integrate Operations Strategies into a Sustainable and Circular Supply Chain

Companies are involved in a context that involves fierce competitiveness, globalisation and worldwide requirements, including environmental care. This means that they must consider strategies to make their supply chains more sustainable in their operations planning. Therefore, this study proposes addressing the dimensions and challenges that companies must address to design their supply chains within the circular economy framework. For this reason, a conceptual framework design methodology is used, and this article addresses the visualisation, analysis and conceptualisation phases as a fundamental basis for subsequently planning the modelling, validation and proposal to define a conceptual model for the design of operations strategies in sustainable global supply chains in line with circular economy criteria. The obtained results show that the main dimensions considered by experts are: political, economic, social, technological, legal and environmental. The challenges to which these dimensions are exposed are cost, agility, flexibility, sustainability, resilience and digitisation.

Urban Light Electric Vehicle for Last Mile Delivery in Low Emission Areas

On the one hand, E-commerce has grown steadily since its inception and last-mile delivery has seen a high expansion. On the other hand, the growing concern about pollution associated with transport is imposing a paradigm shift in the transport of goods, leading to its decarbonization. The fundamental strategy being implemented by logistics operators is the transformation of their fleets to electric vehicles. This paper presents five possible innovative solutions for last-mile delivery that can be used in low or zero-emission areas and even in areas with no access to road traffic. As a conclusion, only one of them is fully implemented and in use today, e-cargo bikes. The other options, although very efficient and promising solutions, require large investments, further technological development and/or greater customer acceptance.

Heijunka and Jidoka in Spanish Research. A Systematic Literature Review

After four decades of successful spread of lean production, fundamental practices such as heijunka and jidoka seem rarely mentioned in Spanish forums. This paper explores, through a systematic review of the literature, the scientific production carried out by Spanish researchers related to the heijunka and jidoka methodologies. The papers reveal two strong research streams that allow the technological development of both practices and their application in Industry 4.0. However, further studies are required on industrial settings. The diffusion of both techniques in Spanish manufacturing plants can be felt intuitively, but not enough data are available for their characterization.

Single-Station Unrelated Parallel Machines Scheduling Problem: A Case Study in a Real Factory

This paper solves the production planning for a real wind tower plant. Specifically, it solves the bottleneck station of the plant, which has machines with a speed that depends both on the machine and on the job itself to be produced, i.e. Unrelated Parallel Machines. In addition, among these machines there is one with lower capacity that cannot complete the jobs, so it is proposed to use it as a support for the rest of the machines that can, and therefore conserve the resource. To solve this problem, the adaptation of the Genetic Algorithm and a Constructive Heuristic developed for this type of problem are presented. Finally, a set of real data provided by the factory is used for comparison. The maximum Completion Time and the execution times of each algorithm are shown and compared.

A Replication Study on Prosocial Choice

The scientific community, or at least some fields, has faced a replicability crisis over the past decade. This paper presents a successful replication study on prosocial behaviour, where individuals benefit others at a cost to themselves. The morality preference hypothesis, which suggests that people obtain utility from doing what they believe is morally right, is supported by the experimental work from Tappin and Capraro. In this work, we replicate their findings in an unpaid setting and provide additional support for previous experimental results regarding the role of economic motivation in experiments. Furthermore, we find evidence to suggest that hyper-altruistic behaviour diminishes as the stakes increase.

Monte Carlo Simulation for Project Risk Prioritisation

Qualitative project risk assessment is standard practice in project management and involves prioritising risks using a probability and impact matrix. Due to the shortcomings of using this tool for risk prioritisation (poor resolution, errors, suboptimal resource allocation or ambiguous inputs and outputs, among others), we propose a quantitative prioritisation of project risks in this article, analysing the impact of each risk on the project’s duration and cost objectives.

Linear Representation of Greenhouse Gas Emissions Along Industrial Value Chains Using Environmentally Extended Input–output Tables

We studied greenhouse gas (GHG) emissions (CO2-eq) along industrial value chains and represented their dependency links linearly as the first step in assessing the GHG reducing potential of the circular economy. The applied method extended the input–output table for the Spanish economy to integrate GHG emissions. We then simplified the matrix to ensure acceptable representation of emissions using methods such as emission filtering and triangulation of matrices. Finally, we performed a backwards classification (Link-x) of the resulting emissions to assess their locations along industrial value chains. This allowed us to graphically represent a linear configuration of 20 industrial manufacturing value chains, the relationships between the intersectoral links, and the resulting emissions, with 94.5% of total emissions included. This provided the basic information for further analysis of the circular economy’s potential for reducing GHG emissions depending on the circularity achieved.

Food Banks in a Complex Reality: Multi-objective Optimization of Nutritional Composition of Food Baskets

Food insecurity affects millions of people worldwide, and food banks play a vital role in addressing this issue. However, creating nutritionally balanced and equitable food baskets within a complex context poses significant challenges. In this paper, we propose a multi-objective optimization model that considers factors such as nutritional requirements, dietary restrictions, product expiration, and budget constraints. The model aims to assist food banks in creating food baskets that maximize nutritional coverage while promoting fairness and balance. We demonstrate the effectiveness of the model in achieving balanced nutrition and equitable distribution among beneficiaries using real data. Specifically, we applied the model to a case study of a food bank located in Terrassa, Catalonia. Our results indicate that the model can effectively optimize the allocation of food products while considering overall nutritional coverage, fairness, and balance, demonstrating its potential as a tool for food banks in addressing food insecurity.
