A Multi-Objective Coordinated Operation Model for Supply Chain with Uncertain Demand Based on Fuzzy Interval

The coordinated operation process of a class of supply chain with uncertain demands is considered. The supply chain consists of a manufacturer, a supplier and several customers. The semi-finished products of the supplier are raw materials of the manufacturer; demands of customers are uncertain and can be described as fuzzy intervals. A multi-objective programming model for coordinated operation of the supply chain is constructed and a numerical example is proposed. The results of the numerical example shows that decision makers can obtain an optimal operation strategy by using the model proposed in this study according to the level of uncertainties of demands and the operation strategy possesses robustness in some ways.
