In this research, a four-echelon supply chain network (SCN) comprised of suppliers producing different modules, a product assembler, warehouses, and markets is considered. When designing an SCN, it is important to assess non-dominated solutions. Various methods used to solve such problems place emphasis on objectives either at the beginning of the solution process or interactively during the solution process. However, assigning weights in the beginning may lead to skipping some valuable solutions. To address this problem, Pokharel (2008) proposed a two-objective linear programming model for decision-making in a supply chain using a STEP method. Depending on the decision-maker's preferences, the STEP method generates non-dominated solutions. However, the preferences of the decision-maker do not necessarily generate a new solution. This paper develops a solution procedure for obtaining Pareto optimal solutions for Pokharel's SCN model.
