Abstract

Supplier selection is a multicriteria problem which includes both qualitative and quantitative factors. In order to select the best suppliers it is necessary to make a trade off between these tangible and intangible factors some of which may conflict. When capacity constraints exist, this problem becomes more complicated as, in these circumstances, managers should decide about two problems: which suppliers are the best and how much should be purchased from each selected supplier. Some authors have applied mixed integer, goal and multi-objective programming to solve this problem. As these techniques are mathematical, they have significant problems in considering qualitative factors which are very important in supplier selection, especially when supplier partnership is desired. In this article an integration of a analytical hierarchy process and linear programming is proposed to consider both tangible and intangible factors in choosing the best suppliers and placing the optimum order quantities among them such that the total value of purchasing (TVP) becomes maximum. This model can be applied to supplier selection with and without capacity constraints. A numerical example is presented and the model advantages are discussed.

Temporary safety zone site selection during haze Pollution: An integrated approach with FAHP and FTOPSIS
2024, Expert Systems with Applications
Haze pollution poses significant health risks, driving organizations to mitigate its impact. Temporary safety zones are essential for protecting people during haze pollution incidents. However, current strategies may fall short in meeting demand under certain conditions. To address this challenge and aid decision-making, we propose a methodology for selecting temporary safety zone sites during haze pollution. The methodology integrates the Fuzzy Analytic Hierarchy Process (FAHP), the Fuzzy Technique for Order Performance by Similarity to Ideal Solution (FTOPSIS), and a fuzzy mathematical model. Criteria for site selection are established through literature reviews and expert interviews and the FAHP assigns weights to each criterion. FTOPSIS evaluates candidate locations based on the criteria, generating scores for each site. Finally, a multi-objective fuzzy mathematical model identifies optimal locations, considering budget limits, capacity restrictions, and other constraints. We validated the approach in the Sarapee district in Thailand. The results demonstrate the model’s ability to generate optimal solutions, identifying suitable locations for temporary safety zones during haze pollution crises. This research is significant for decision-makers and governments who need to strategically place temporary safety zones and safeguard communities from the hazards of haze pollution. By adopting this integrated approach, organizations can enhance their response to haze pollution incidents, protecting public health and well-being.
A robust method for avoiding rank reversal in the TOPSIS
2022, Computers and Industrial Engineering
The ability to obtain robust ranking results is an important reference factor when choosing a method for multiple criteria decision-making (MCDM). However, the rank reversal phenomenon of MCDM makes its credibility greatly compromised, as represented by the technique for order preference by similarity to ideal solution (TOPSIS). Although some research papers have presented interesting ideas and solutions to minimize/void rank reversal in relation to the TOPSIS, there are still some gaps that need further research, such as do not utterly eliminate the rank reversal, need more additional decision information, cannot theoretically guarantees the stability of ranking. Therefore, an improved TOPSIS method, named IE-TOPSIS, is developed based on information expansion and virtual ideal points. An algorithm for the extreme value extension of criteria indicators is initially constructed, based on the existing decision-making information, which can effectively avoid the influence of the data standardization process on decision-making ranking. And then, the concept of a virtual ideal point is proposed, which can prevent the rank reversal caused by the change of ideal points in varying decision-making environments. At the same time, this paper proves that the IE-TOPSIS satisfies ranking stable according to the given definition of ranking robust, which theoretically guarantees that the rank reversal phenomenon does not exist. In the case where the IE-TOPSIS is established, a new ranking index is proposed that can better distinguish the evaluation objects and solve the problem that the classic TOPSIS ranking index cannot completely rank the decision objects. Finally, in the verification of examples, the ranking results show that the improved TOPSIS has strong consistent with the theoretical analysis, and is robust to handle rank reversal phenomenon in all the scenarios in comparison with other studies available in the literature.
A theme evolution and knowledge trajectory study in AHP using science mapping and main path analysis
2022, Expert Systems with Applications
The rapid development of the analytic hierarchy process (AHP) results numerous theoretical and empirical documents. However, as far as we know, there is no literature focus on the theme evolution and knowledge trajectory of the AHP field until now, which makes it difficult for scholars to grasp the research priorities in this domain. To fill this gap, this study conducts science mapping analysis and main path analysis (MPA) on 1326 documents retrieved from Web of Science (WoS) to explore knowledge development and the main research fronts in the AHP field. This study first reflects the evolution trend of the theme through science mapping analysis based on co-word analysis, and proposes six outstanding research areas in the AHP field. Then, through MPA based on citation relationship, this study finds that outsourcing is one of the future research trends. Overall, this paper not only provides researchers with a comprehensive overview of the AHP domain, but also helps practitioners find the cutting-edge application areas and methods.
