The special issue includes 15 contributions presenting new and significant research in the relevant area. Contributions mainly present either a novel green/sustainable manufacturing supply chain design and operations decision support approach applied to a problem, or a state-of-the-art method on green/sustainable factors in supply chain design and operations. The article delineates an overview of the contributions and their significance, and an introspection on the 'green' factors involved.

These imprecise information often hinder decision makers to make a fruitful decision in regard to optimal product-mix to be manufactured. To make it ease for the decision makers while making a robust decision for product-mix optimization problems, a fuzzy linear programming (FLP) model is presented in this paper. The present methodology is a fuzzy linear programming model having fuzzification of both the objective function coefficients and fuzzy resources. An example of a chocolate manufacturing firm has been delineated to validate the practicability of the proposed FLP approach. The degree of optimality and the level-of-satisfaction of the solution have been discussed at the end of this paper.

The elements of a green supply-chain network tend to operate on reduced carbon emissions. This article addresses the current challenges in the design of a green dairy manufacturers’ supply-chain network in the east of Ireland by minimising both the total cost of operating facilities and total carbon emissions. An integrated multi-objective location-routing methodology, using mixed-integer programming, has been formulated for an optimal design of the green Irish food market supply-chain network. The devised mixed-integer programming model is integrated with a multi-criteria decision-making tool called “Analytic Hierarchy Process” (AHP). A two-layer location-routing problem is considered on the demand side of the supply-chain. Finally a set of candidate alternative solutions are obtained using MOGA-II optimiser. The efficacy of the proposed model is delineated using an example from Irish food market.

It utilizes a smooth logistic membership function for finding out the fuzziness patterns in the disparate level of satisfaction. This membership function has been validated for applying to the real-world product-mix problems. This contribution provides a robust, quantified monitoring of the level of satisfaction among the decision makers, and calibrates these levels of satisfaction against the decision-makers expectations. It thus provides a computational intelligence procedure. The solution by Hsu and Chung via the dominance-rule technique yields the optimal throughput as US $ 11,873, which is identical to the solution found by the fuzzy-logic-programming (FLP) methodology, and is considered to be better suited for the product-mix-selection problems. The flexibility of the model lies in the membership function design. The chapter concludes by discussing the inefficiency of the traditional linear programming in handling the multiple bottleneck problems, through the TOC concept via an illustrative example.

This work's theoretical bases combine and reconcile three major areas: supply chain management, environmental management and performance measurement. Researchers have suggested many empirical criteria for green supply chain (GSC) performance measurement and proposed both qualitative and quantitative frameworks. However, these are mainly operational in nature and specific to the focal company. This research develops an innovative GSC performance measurement framework by integrating supply chain processes (supplier relationship management, internal supply chain management and customer relationship management) with organisational decision levels (both strategic and operational). Environmental planning, environmental auditing, management commitment, environmental performance, economic performance and operational performance are the key level constructs. The proposed framework is then applied to three selected manufacturing organisations in the UK. Their GSC performance is measured and benchmarked by using the analytic hierarchy process (AHP), a multiple-attribute decision-making technique. The AHP-based framework offers an effective way to measure and benchmark organisations' GSC performance. This study has both theoretical and practical implications. Theoretically it contributes holistic constructs for designing a GSC and managing it for sustainability; and practically it helps industry practitioners to measure and improve the environmental performance of their supply chain.
