Product Warranty Period: A Markovian Approach to Estimation and Analysis of Repair and Replacement Costs.
将保修期内的产品维修更换过程建模为随机过程，利用马尔可夫状态估计保修成本，适用于会计期间内多期销售产品的保修成本分析。
Abstract ABSTRACT: This article describes the repair-replacement process of a product under warranty as a stochastic process and develops a model to estimate the costs due to warranty. The product is assumed to be made up of several components for which failure rates are available. Markovian states are defined dependent on the number of failures of each component. A replacement policy is superimposed, and an approach to obtaining the transition probabilities is illustrated when the failures are solely due to chance. The use of the model to estimate the warranty costs during an accounting period, when there are warranties outstanding for the products sold during prior periods in addition to the products sold during the current period, is discussed.
