Accounting for Product Wearout Cost
提出一个随机模型，描述产品在保修期后磨损阶段的故障现象，并帮助估算维护协议期间的维修成本，可用于定价决策和任意会计期间的成本核算。
Maintenance agreements typically take effect when products have survived their warranty periods and begun to wear out. This paper proposes a stochastic model that both describes the breakdown phenomena that affect products and facilitates estimating repair costs during a maintenance agreement period. The model, thus, may be used for pricing decisions. The usefulness of the approach in estimating costs during an arbitrary accounting period is illustrated.
