A Model and an Algorithm for a Large-Scale Sustainable Supplier Selection and Order Allocation Problem

Abstract: We consider a buyer’s decision problem of sustainable supplier selection and order allocation (SSS & OA) among multiple heterogeneous suppliers who sell multiple types of items. The buyer periodically orders items from chosen suppliers to refill inventory to preset levels.

“…A linear program (LP) is an optimization problem consisting of a linear objective function (maximizing or minimizing), linear equality, or inequality constraints. It is ubiquitous in many areas of applied science, such as airline crew scheduling problems [1][2][3], labor scheduling problems [4], diet problems [5], and supplier selection and order allocation problems [6].…”

Evaluating and selecting the best set of suppliers is a challenging decision in outsourcing and it plays a significant role in supply chain performance [1,2]. Traditionally the supplier selection and order allocation decision is made based on cost and quality criteria.…”
