Purchasing Planning and Order Allocation in the Pharmaceutical Sustainable Supply Chain with Using Theoretical-Graph (GT-MP- DM) (Case Study: Supplying the clotting factor for patients with hemophilia)

Abstract

In view of the growing environmental consciousness among product users, the issue of product sustainability is one of the challenging tasks being faced by product designers, manufacturers,environmentalists and, decision makers.This article presents a framework for supplier selection from sustainability perspective.In this study, along with the sustainability criteria, the other criteria and sub-criteria involved in the selection of drug suppliers for patients with hemophilia have been investigated. Regarding to the significance of the clotting agents in health and life of the hemophilia patients, it is especially important to provide and supply this drug from the safe companies and the amount of ordering it is significant. The studied criteria and sub-criteria in this article have been investigated and concluded through using library studies, filed assessments of the experts’ comments; and the desired supplier has been determined, and the others have been ranked through the Graph Theoretical Matrix Permanent Dicision Making(GT-MP-DM) Approach. Finally, with presenting the bi-objective mathematical model, the amount of order to the suppliers has been determined and then the model has been solved by means of fuzzy MAX-MIN method and GAMS software; then the model has been validated by sensitivity analysis.
