Setup Reduction and Increased Effective Capacity
研究多产品企业中减少换模时间如何提升有效产能，基于EOQ模型推导最优换模时间缩减和加班决策，并用数值例子说明。
Setup reduction is an important aspect of the Just-In-Time (JIT) and Zero Inventory (ZI) concepts. This paper looks at the increased effective capacity that results from setup reduction. A certain amount of time, as well as expense, is required for each setup within a multiproduct firm. By reducing the time required for setups, less time is required to carry out those setups. That time can either be used to reduce lot sizes or to reduce overtime. We use an EOQ-like setting with stationary deterministic demand rates for each product. This simple model allows explicit solutions to be derived, not only for optimal setup time reduction, but for optimal overtime as well. Numerical examples illustrate the results.
