Supplier Selection and Ranking Towards Sustainable Procurement with Multiple Decision Makers The paper proposes a holistic selection and ranking approach for supplier evaluation and purchasing order allocation among suppliers who meet acceptable triple bottom line (TBL) performance. Supplier ranks are developed using judgements from multiple decisionmakers. Purchasing order allocation among the ranked suppliers is determined using a linear programming (LP) model, which minimizes the total purchasing cost subject to multiple TBL based constraints. This research enables decisionmakers to incorporate sustainability conditions in the supplier evaluation as the basis for best practice with an industry friendly approach, which relies on input from key functional units for a holistic organization wide decision. The proposed approach is expected to motivate decisionmakers to consider sustainable perspectives in supplier evaluation and order allocation processes in a global supply chain. This paper illustrates the applicability of the approach using a cementmanufacturing scenario in an emerging economy.

Development of a Quadruple Bottom Linebased Composite Sustainability Index to Measure Sustainable Performance Manufacturing companies worldwide are faced with the critical issue of sustainable development. The aim of this paper is to develop a quadruple bottom linebased composite sustainability index which can be used by manufacturing firms in measuring their sustainable performance. The proposed index simultaneously considers a firmu0027s economic performance, social performance, environmental performance, and corporate governance. Field study results indicated that an index having a value from 0 to 1 can indeed be computed based on several sustainability indicators expressed in varying units. The index can be employed for performance evaluation to monitor the sustainable performance of a manufacturing company through the years. It can also be utilized for benchmarking to compare sustainable performance with other firms.
