碩士 / 朝陽科技大學 / 工業工程與管理系碩士班 / 100 / This research explores the optimization of a production system with multiple products and multiple delivery under a common cycle policy, and determines the best production run time strategy for a system with machine breakdown, rework, andmultiple deliveries.Two mathematical models are constructed respectively. Model 1 studies the multi-item production system with imperfect rework and model 2 investigates the optimal production run time for a system with Poisson breakdown rate and reworking of defective items. Hessian matrix equations are used in model 1 to prove existence of minimal cost, followed by the derivation of the optimal rotation cycle time and optimal number of deliveries. Conditional optimality and a search algorithm are employed in model 2 to locate the optimal production run time. Examples are provided to demonstrate how the results can be used in real world situations.
