在本文中，我们制定了在随机机器故障的生产环境中预防性维护和安全库存策略的分析模型。传统上，预防性维护和安全库存已作为应对机器故障的两种不同策略进行独立研究。我们的目的是开发一个统一的框架，以便共同考虑两者。我们说明了投资这两种选择之间的权衡。此外，我们还提供了最优条件，在该条件下应实施一种或两种策略以最小化相关成本函数。具体来说，详细分析了具有确定性和指数修复时间分布的情况。我们提供数值示例来说明预防性维护和安全库存最佳策略的确定。 © 1997 约翰威利父子公司。
In this article we formulate an analytical model of preventive maintenance and safety stock strategies in a production environment subject to random machine breakdowns. Traditionally, preventive maintenance and safety stocks have been independently studied as two separate strategies for coping with machine breakdowns. Our intent is to develop a unified framework so that the two are jointly considered. We illustrate the trade-off between investing in the two options. In addition, we provide optimality conditions under which either one or both strategies should be implemented to minimize the associated cost function. Specifically, cases with deterministic and exponential repair time distributions are analyzed in detail. We include numerical examples to illustrate the determination of optimal strategies for preventive maintenance and safety stocks. © 1997 John Wiley & Sons, Inc.
