基于随机需求、随机提前期的（Q，R）库存模型

摘要

The (Q,R) inventory model is the important model for inventory management, And also at present, the research about (Q,R) inventory model often assumes that lead time is a constant, But in the fact, lead time is not a constant. In this paper, we will set a (Q,R) inventory model based stochastic lead time and analyses the sensitivity of the related parameters,Finally, we use an example to show that the model is scientific and practical.%（Q，R）库存模型是库存管理中的重要模型，而目前关于（Q，R）库存模型的研究常常假设提前期为常数，但在现实生产中，提前期很少是常数。文章在前人研究的基础上，将提前期视为随机变量，建立了基于随机需求、随机提前期的（Q，R）库存模型，最后通过一个实例验证了模型的科学性和实用性。
