Evaluation of base-stock policies in multiechelon inventory systems with state-dependent demands. Part II: State-dependent depot policies
研究一个两级库存系统，零售商需求率受连续时间马尔可夫链影响，仓库采用状态依赖的基础库存策略，并计算了仓库和零售商的客户延迟精确稳态分布。
We consider a two-echelon inventory system where the exogenous demands occur only at the retailer locations, and the demand rates are functions of an underlying continuous-time Markov chain. This underlying process may represent, for example, general economic conditions, the number of active users in the system, et cetera. Each retailer location follows a base-stock policy that is independent of the process. However, the warehouse (central depot) follows a state-dependent base-stock policy. We develop a procedure to compute the exact steady-state customer-delay distribution for both the warehouse and the retailer locations. © 1996 John Wiley & Sons, Inc.
