Multi crteria decision making and its applications : a literature review
This paper presents current techniques used in Multi Criteria Decision Making (MCDM) and their applications. Two basic approaches for MCDM, namely Artificial Intelligence MCDM (AIMCDM) and Classical MCDM (CMCDM) are discussed and investigated. Recent articles from international journals related to MCDM are collected and analyzed to find which approach is more common than the other in MCDM. Also, which area these techniques are applied to. Those articles are appearing in journals for the year 2008 only. This paper provides evidence that currently, both AIMCDM and CMCDM are equally common in MCDM

Decision support for build-to-order supply chain management through multiobjective optimization
This paper aims to identify the gaps in decision-making support based on
multiobjective optimization for build-to-order supply chain management (BTOSCM).
To this end, it reviews the literature available on modelling build-to-order
supply chains (BTO-SC) with the focus on adopting multiobjective optimization
(MOO) techniques as a decision support tool. The literature has been classified based
on the nature of the decisions in different part of the supply chain, and the key
decision areas across a typical BTO-SC are discussed in detail. Available software
packages suitable for supporting decision making in BTO supply chains are also
identified and their related solutions are outlined. The gap between the modelling and
optimization techniques developed in the literature and the decision support needed in
practice are highlighted and future research directions to better exploit the decision
support capabilities of MOO are proposed
Decision makings in key remanufacturing activities to optimise remanufacturing outcomes : a review
The importance of remanufacturing has been increasing since stricter regulations on protecting the environment were enforced. Remanufacturing is considered as the main means of retaining value from used products and components in order to drive a circular economy. However, it is more complex than traditional manufacturing due to the uncertainties associated with the quality, quantities and return timing of used products and components. Over the past few years, various methods of optimising remanufacturing outcomes have been developed to make decisions such as identifying the best End-Of-Life (EOL) options, acquiring the right amounts of cores, deciding the most suitable disassembly level, applying suitable cleaning techniques, and considering product commonality across different product families. A decision being made at one remanufacturing activity will greatly affect the decisions at subsequent activities, which will affect remanufacturing outcomes, i.e. productivity, economic performance effectiveness, and the proportion of core that can be salvaged. Therefore, a holistic way of integrating different decisions over multiple remanufacturing activities is needed to improve remanufacturing outcomes, which is a major knowledge gap. This paper reviews current remanufacturing practice in order to highlight both the challenges and opportunities, and more importantly, offers useful insights on how such a knowledge gap can be bridged

Application of Multi-Objective Optimization Based on Genetic Algorithm for Sustainable Strategic Supplier Selection under Fuzzy Environment
Purpose: The incorporation of environmental objective into the conventional supplier selection
practices is crucial for corporations seeking to promote green supply chain management (GSCM).
Challenges and risks associated with green supplier selection have been broadly recognized by
procurement and supplier management professionals. This paper aims to solve a Tetra “S” (SSSS)
problem based on a fuzzy multi-objective optimization with genetic algorithm in a holistic supply
chain environment. In this empirical study, a mathematical model with fuzzy coefficients is
considered for sustainable strategic supplier selection (SSSS) problem and a corresponding model
is developed to tackle this problem.
Design/methodology/approach: Sustainable strategic supplier selection (SSSS) decisions are
typically multi-objectives in nature and it is an important part of green production and supply
chain management for many firms. The proposed uncertain model is transferred into
deterministic model by applying the expected value measure (EVM) and genetic algorithm with weighted sum approach for solving the multi-objective problem. This research focus on a multiobjective
optimization model for minimizing lean cost, maximizing sustainable service and
greener product quality level. Finally, a mathematical case of textile sector is presented to
exemplify the effectiveness of the proposed model with a sensitivity analysis.
Findings: This study makes a certain contribution by introducing the Tetra ‘S’ concept in both
the theoretical and practical research related to multi-objective optimization as well as in the study
of sustainable strategic supplier selection (SSSS) under uncertain environment. Our results
suggest that decision makers tend to select strategic supplier first then enhance the sustainability.
Research limitations/implications: Although the fuzzy expected value model (EVM) with
fuzzy coefficients constructed in present research should be helpful for solving real world
problems. A detailed comparative analysis by using other algorithms is necessary for solving
similar problems of agriculture, pharmaceutical, chemicals and services sectors in future.
Practical implications: It can help the decision makers for ordering to different supplier for
managing supply chain performance in efficient and effective manner. From the procurement and
engineering perspectives, minimizing cost, sustaining the quality level and meeting production
time line is the main consideration for selecting the supplier. Empirically, this can facilitate
engineers to reduce production costs and at the same time improve the product quality.
Originality/value: In this paper, we developed a novel multi-objective programming model
based on genetic algorithm to select sustainable strategic supplier (SSSS) under fuzzy
environment. The algorithm was tested and applied to solve a real case of textile sector in
Pakistan. The experimental results and comparative sensitivity analysis illustrate the effectiveness
of our proposed model.Peer Reviewe
Decision Support System for Managing Reverse Supply Chain
Reverse logistics are becoming more and more important in the overall Industry area because of the environment and business factors. Planning and implementing a suitable reverse logistics network could bring more profit, customer satisfaction, and an excellent social picture for companies. But, most of the logistics networks are not equipped to handle the return products in reverse channels. Reverse logistics processes and plans rely heavily on reversing the supply chain so that companies can correctly identify and categorize returned products for disposition, an area that offers many opportunities for additional revenue. The science of reverse logistics includes return policy administration, product recall protocols, repairs processing, product repackaging, parts management, recycling, product disposition management, maximizing liquidation values and much more. The focus of this project is to develop a reverse logistics management system/ tools (RLMS). The proposed tools are demonstrated in the following order. First, we identify the risks involved in the reverse supply chain. Survey tool is used to collect data and information required for analysis. The methodologies that are used to identify key risks are the six sigma tools, namely Define, Measure, Analyse, Improve and Control (DMAIC), SWOT analysis, cause and effect, and Risk Mapping. An improved decision-making method using fuzzy set theory for converting linguistic data into numeric risk ratings has been attempted. In this study, the concept of ‘Left and Right dominance approach’(Chen and Liu, 2001) and Method of ‘In center of centroids’ (Thoran et al., 2012a,b) for generalized trapezoidal fuzzy numbers has been used to quantify the ‘degree of risk’ in terms of crisp ratings. After the analysis, the key risks are identified are categorized, and an action requirement plan suggested for providing guidelines for the managers to manage the risk successfully in the context of reverse logistics. Next, from risk assessment findings, information technology risk presents the highest risk impact on the performance of the reverse logistics, especially lack of use of a decision support system (DSS). We propose a novel multi-attribute decision (MADM) support tool that can categorizes return products and make the best alternative selection of recovery and disposal option using carefully considered criteria using MADM decision making methodologies such as fuzzy MOORA and VIKOR. The project can be applied to all types of industries. Once the returned products are collected and categorized at the retailers/ Points of return (PoR), an optimized network is required to determine the number of reprocessing centres to be opened and the optimized optimum material flow between retailers, reprocessing, recycling and disposal centers at minimum costs. The research develops a mixed integer linear programming model for two scenarios, namely considering direct shipping from retailer/ PoR to the respective reprocessing centers and considering the use of centralized return centers (CRC). The models are solved using LINGO 15 software and excel solver tools respectively. The advantage of the implementation of our solution is that it will help improve performance and reduce time. This benefits the company by having a reduction in their cost due to uncertainties and also contributes to better customer satisfaction. Implementation of these tools at ABZ computer distributing company demonstrates how the reverse logistics management tools can used in order to be beneficial to the organization. The tool is designed to be easily implemented at minimal cost and serves as a valuable tool for personnel faced with significant and costly decisions regarding risk assessment, decision making and network optimization in the reverse supply chain practices
