Replacement-Policy Development: A Case Study of Glove Replacement at a Nuclear Processing Facility
研究了核处理设施中防护手套的最优替换政策，通过修改经典替换模型，将手套寿命视为正态分布变量，并引入成本比进行敏感性分析，为制定最小成本替换策略提供指导。
Individual/group replacement models were used to identify the minimum-cost policy for replacing protective gloves that are utilized in product fabrication at a nuclear processing facility. Since historical data on glove longevity were not available to determine the failure-rate distribution, the classical replacement model for items that fail was modified to consider glove life as a normally distributed variable. Moreover, the absence of replacement-cost required that the classical model be transformed to incorporate the ratio of single to unit-group replacement cost. Sensitivity analysis on these two input parameter values provided guidance for the development of an appropriate replacement policy.
