DEA-Based Production Planning Changes in General Situation

In great producing organizations(such as factory with several workshops)and chain stores supplying products (such as chain supermarkets and restaurants) under consideration the central decision-making unit, usually there are several DecisionMaking Units(DMUs) participate in total production and supply. The purpose of this research is to present new input and output plans ,determined by central Decision-Making Unit, for all DMUs. In this plan, demand changes and input changes can be predicted for the next production season. This new production plan has been presented through optimizing the average or overall production performance of the entire organization, measured by BCC efficiency.By using new plans the efficiency of each DMU will be maximized. It is supposed that all DMUs are able to improve their input usages and output productions. To illustrate this approach, two simple numerical examples and a real data for twenty restaurant chains are used.
