We consider order-quantity / reorder-point inventory models where the availability of supply is subject to random fluctuations. We use concepts from renewal reward processes to develop average cost objective function models for single, two, and multiple suppliers. Identifying the regenerative cycle

โฆ Synopsis
This article presents a recoverable spares model for performance evaluation in a multiechelon inventory environment. This model explicitly incorporates the phenomenon known as multiple failures, in which more than one part can require replacement or repair when an end-item reaches a maintenance base. The model is shown to be computationally intractable, and an approximation scheme is presented to estimate system performance.

We study an infinite horizon periodic stochastic inventory system consisting of retail outlets and customers located on a homogenous line segment. In each period, the total demand, generated by the customers on the line, is normally distributed. To better match supply and demand, we incorporate late
The paper deals with discrete-time regression models to analyze multistate-multiepisode failure time data. The covariate process may include fixed and external as well aa internal time dependent covarjates. The effects of the covariates may differ among different kinds of failures and among successi
