A DECISION-SUPPORT MODEL FOR THE INITIAL DESIGN OF FMS

This study proposes a decision support model for the design and evalua tion of FMS. The model optimizes the profit by analyzing the interacti on between candidate part types and FMS configuration under the constr aints of production requirement and cost effectiveness. The model is s olved by using the closed queueing network model and optimization mode l iteratively. The throughput of current FMS configuration is evaluate d by the closed queueing network model, and then its results are fed t o the optimization model for the selection of best combination of part types and production resources. The resulting solution gives answers to a series of decision problems at the initial design stage of FMS. A n example problem is presented to show the superiority of the proposed approach.
