Abstract:
The strong competition in today s global markets and huge customer attention to factors such as price, quality, time of delivery and product variety has caused the investors to focus on supply chain management. In this regard, selecting the choosing and determining the quota of each echelon of chain is one of the most important and crucial decisions that not only is responsible for supplying the parts, but also accountable for maintaining the organization in the competitive environment. This paper aims at designing a four-echelon supply chain structure including multiple suppliers, multiple producers, multiple distributors and multiple customers for determining the optimal order of each product in a multi-objective and multi-period problem. The considered multiple objective functions include minimizing total purchase, transportation costs, shortage cost and holding cost, also maximizing total score of each one. Due to the importance of each level, the model has investigated synchronic for all of them.
