Selection Of Collection Centers And Recovery Facilities For Designing A Reverse Supply Chain, Surendra Gupta, Gupta Sushil, Pochampally Kishore
Surendra M. Gupta
The designing of a reverse supply chain must involve selection of collection centers and recovery facilities that have sufficient success potentials. These success potentials depend heavily on the participation of the following three important groups who have multiple, conflicting, and incommensurate criteria for evaluation, and so, the potentials must be evaluated based on the maximized consensus among those groups: (i) Consumers (whose primary concern is convenience), (ii) Local government officials (whose primary concern is environmental consciousness), and (iii) Supply chain company executives (whose primary concern is profit). In this paper, we propose a three-phase multi-criteria group approach to select collection …

A Fuzzy Ahp-Based Approach For Selecting Potential Recovery Facilities In A Closed Loop Supply Chain, Surendra Gupta, Satish Nukala

In this paper, we employ fuzzy AHP methodology for selecting potential recovery facilities in a closed-loop supply chain. This methodology utilizes triangular fuzzy numbers for pair-wise comparisons and the extent analysis method for the synthetic extent value of the fuzzy pair-wise comparisons and principle of comparison of fuzzy numbers to derive the weight vectors to address the criticism traditional AHP often faces due to its unbalanced scale of judgments and inability to handle inherent uncertainty in carrying out pair-wise comparisons. A numerical example is considered to illustrate the methodology.
