本文涉及连续审查（s，S）库存系统，其中到达的需求发现系统缺货，离开服务区域并在一段随机时间后重复他们的请求。这一假设引入了基于需求损失模型或积压模型的经典方法的自然替代方案。随机模型公式基于二维马尔可夫过程，通过数值求解来研究系统的基本运行特性。还考虑了优化设计问题。
This paper deals with a continuous review (s,S) inventory system where arriving demands finding the system out of stock, leave the service area and repeat their request after some random time. This assumption introduces a natural alternative to classical approaches based either on lost demand models or on backlogged models. The stochastic model formulation is based on a bidimensional Markov process which is numerically solved to investigate the essential operating characteristics of the system. An optimal design problem is also considered.
