Abstract: | In this paper, we develop an analytical model to estimate several performance measures in a single-item, multi-company, repairable inventory system where complete pooling of stock is permitted among the companies. Compared to previous research, this paper is different in that both non-zero lateral transshipment time and delayed lateral transshipments are considered in the model. We model the system as a multi-dimensional Markovian problem and solve it using a two-stage solution method. The proposed method is very accurate and computationally efficient. |
