碩士 === 朝陽科技大學 === 工業工程與管理系碩士班 === 101 === This study investigated the production run time of a single production containing the random machine breakdown, (n+1) multiple of delivery and perfect rework, the two-stage production and two-stage delivery. Assuming an imperfect production process that will produce defective products, and they can all be reworked and repaired at the end of the production process. In actual situation the traditional EPQ (Economic Production Quantity) model continuous distribution assumption is not practical, we adope (n+1) multiple distribution to address it and build mathematical model for this problem. We study three types of mathematical models based on the above assumptions: (1) when the machine breakdown in the first stage of the production process (before the first delivery) (2) when the machine breakdown in the second stage of the production process (after first delivery), and (3) no breakdown happens. Finally, integration of these three models are done, and numerical examples validation are provided and sensitivity analysis for the different parameter values are conducted, this study is expected to meet the actual situation of the industry today, and the results can be provided as a reference for their decision-making.
