Abstract


In real world, supply chain works as interrelating network of suppliers, manufacturers, distributers, and customers to satisfy customer satisfaction. Because of the nature of the conflicting objective functions that affect the performance of supply chain management, coordinate all phases of supply chain as a whole should be considered. This paper presents the solutions for integrated production and distribution planning problem and investigates the effectiveness of their integration through a computational study. The environment is a multi-plant, multi-retailers, multi-item and multi-period where the objective functions are total cost, delivery time, and quality. The model is implemented using Fuzzy Linear Programming (FLP), Goal Programming (GP), and Fuzzy Goal Programming (FGP) approaches. The results obtained by using lingo 11.0 software show that the proposed FGP provides high quality solution as well as the effectiveness of the integrated model over the decoupled one.
