传统上，在可修系统的最优维修策略研究中，与最小维修过程相对应的非齐次泊松过程模型得到了广泛的应用。然而，在许多实际情况下，修复类型不一定是最小的。基于一种新的计数过程模型，提出了一种新的维修过程--广义Polya过程。然后，讨论了最优替换问题。建立了一个二元预防性替换策略，并研究了最优策略的性质。文中还给出了算例。此外，还与传统的替换策略进行了比较。
Traditionally, in the studies of the optimal maintenance policies for repairable systems, the nonhomogeneous Poisson process model, which corresponds to the minimal repair process, has been intensively applied. However, in many practical situations, the repair type is not necessarily minimal. In this article, a new repair process based on a new counting process model (so‐called the generalized Polya process) is introduced. Then, the issue of the optimal replacement problem is discussed. A bivariate preventive replacement policy is developed and the properties of the optimal policy are studied. Illustrative examples are also presented. In addition, a comparison with a conventional replacement policy is performed.
