Abstract

This paper considers the problem of determining optimal disassembly configurations for single and multiple products, that is, which assemblies and subassemblies to disassemble and which to leave intact. The paper first examines the problem of determining revenue-maximizing disassembly configurations for a single product using the hierarchical product tree representation, and develops a linear time algorithm for its solution. This algorithm is then extended to the case where fixed costs may be associated with disassembly of some nodes in the product tree. Finally, the problem of meeting a specified demand for recovered components and subassemblies from an available inventory of recovered products, where disassembly capacity is limited and products may have common components, is formulated as an optimization problem. A column-generation algorithm for this problem is presented that is capable of solving reasonably sized problems in a few seconds of CPU time on average.

Disassembly line balancing under high variety of end of life states using a joint precedence graph approach
2015, Journal of Manufacturing Systems
Citation Excerpt :
LB was first considered in assembly settings but the approach can be extended to the application of disassembly [2,3]. Meacham et al. [4] determined the optimal disassembly configurations for both single and multiple product types for meeting a specified demand for recovered components and subassemblies. Gungor and Gupta [5] investigated the disassembly line balancing problem (DLBP) in the presence of task failures.
Disassembly is an important aspect of end of life product treatment, as well as having products disassembled in an efficient and responsible manner. Disassembly line balancing is a technique that enables a product to be disassembled as efficiently and economically viable as possible; however, considering all possible end of life (EOL) states of a product makes disassembly line balancing very difficult. The EOL state and the possibility of multiple recovery options of a product can alter both disassembly tasks and task times for the disassembly of the EOL product. This paper shows how generating a joint precedence graph based on the different EOL states of a product is beneficial to achieving an optimal line balance where traditional line balancing approaches are used. We use a simple example of a pen from the literature to show how a joint disassembly precedence graph is created and a laptop example for joint precedence graph generation and balancing. We run multiple scenarios where the EOL conditions have different probabilities and compare results for the case of deterministic task times. We also consider the possibility where some disassembly task times are normally distributed and show how a stochastic joint precedence graph can be created and used in a stochastic line balancing formulation.
Depth of manual dismantling analysis: A cost-benefit approach

As evidenced, design parameters usually need to be modified in order to enhance disasseblability. On a CBA basis, one of the first approaches was presented by Gupta (1995) who introduced a technique to analyze the efficiency of designing electronic products for the environment, followed by others who studied optimal dismantling level with the best cost-effectiveness performance (e.g. Meacham et al., 1999; Kaebernick et al., 2000; Kuo, 2000, in press; Lambert, 2007; Vanegas et al., 2012; Wang et al., 2012). Disassembly of EEE is still characterized as labor intensive (e.g. Wang et al., 2012; Santochi et al., 2002; Tang et al., 2002).
This paper presents a decision support tool for manufacturers and recyclers towards end-of-life strategies for waste electrical and electronic equipment. A mathematical formulation based on the cost benefit analysis concept is herein analytically described in order to determine the parts and/or components of an obsolete product that should be either non-destructively recovered for reuse or be recycled. The framework optimally determines the depth of disassembly for a given product, taking into account economic considerations. On this basis, it embeds all relevant cost elements to be included in the decision-making process, such as recovered materials and (depreciated) parts/components, labor costs, energy consumption, equipment depreciation, quality control and warehousing. This tool can be part of the strategic decision-making process in order to maximize profitability or minimize end-of-life management costs. A case study to demonstrate the models’ applicability is presented for a typical electronic product in terms of structure and material composition. Taking into account the market values of the pilot product’s components, the manual disassembly is proven profitable with the marginal revenues from recovered reusable materials to be estimated at 2.93–23.06 €, depending on the level of disassembly.
Multi-objective partial disassembly optimization based on sequence feasibility
2013, Journal of Manufacturing Systems
Citation Excerpt :
Constraining the final disassembly level transforms the partial disassembly problem into a complete or selective disassembly problem. The single objective partial disassembly problem has been studied to varying degrees using various methods [9–18]. Harjula et al. [9] studied partial disassembly assuming that the disassembly sequence is the reverse of the assembly sequence, and [10] determined the optimal disassembly sequence using a Petri-net that incorporated the probabilistic success rate of disassembly operations.
A sustainable manufacturing system integrates production systems, consumer usage behavior, and End-of-Life (EoL) product value recovery activities. Facilitating multi-objective disassembly planning can be a step toward analyzing the tradeoffs between the environmental impact and profitability of value recovery. In this paper, a Genetic Algorithm (GA) heuristic is developed to optimize partial disassembly sequences based on disassembly operation costs, recovery reprocessing costs, revenues, and environmental impacts. EoL products may not warrant disassembly past a unique disassembly level due to limited recovered component market demand, minimal material recovery value, or minimal functional recovery value. The effectiveness of the proposed GA is first verified and tested using a simple disassembly problem and then applied to the traditional coffee maker disassembly case study. Analyses are disaggregated into multiple disassembly network optimization problems, one for each product subassembly, resulting in a bottom-up approach to EoL product partial disassembly sequence optimization.
Environmentally conscious manufacturing and product recovery (ECMPRO): A review of the state of the art
2010, Journal of Environmental Management
Citation Excerpt :
Kim et al. (2009d) propose a branch and bound algorithm for the case of single product type without parts commonality. For the capacitated case, Meacham et al. (1999) present an optimization algorithm by considering common components among products, and limited inventory of products available for disassembly. Lee et al. (2002) develop an IP model based on the minimization of sum of disassembly operation and inventory holding costs.
Gungor and Gupta [1999, Issues in environmentally conscious manufacturing and product recovery: a survey. Computers and Industrial Engineering, 36(4), 811–853] presented an important review of the development of research in Environmentally Conscious Manufacturing and Product Recovery (ECMPRO) and provided a state of the art survey of published work. However, that survey covered most papers published through 1998. Since then, a lot of activity has taken place in EMCPRO and several areas have become richer. Many new areas also have emerged. In this paper we primarily discuss the evolution of ECMPRO that has taken place in the last decade and discuss the new areas that have come into focus during this time. After presenting some background information, the paper systematically investigates the literature by classifying over 540 published references into four major categories, viz., environmentally conscious product design, reverse and closed-loop supply chains, remanufacturing, and disassembly. Finally, we conclude by summarizing the evolution of ECMPRO over the past decade together with the avenues for future research.
