研究了提前期与丢单率相关下订购批量中含有次品的连续检查库存模型,其中上游供应商给予下游商家规模经济订购优惠条件,在到达的整个批量中抽取一部分产品检查,未检查产品的次品由顾客在使用中发现并退还以换取合格品,赶工成本与提前期是一种幂函数形式的关系。文章根据期望短缺量的信息考虑了完全信息情形与部分信息情形。在构建数学模型及求解后对库存系统主要参数进行了灵敏度分析。
This paper studies the continuous inspection inventory model with defective products in the order volume related to the lead time and the losing order rate, in which the upstream suppliers give preferential terms to the downstream merchants for ordering economies of scale, and extracts part of the products in the whole batch of arrival, Defective products are found and returned by customers in use in exchange for qualified products, and rush costs and lead times are a power function relationship. The article considers the situation of complete information and part of information based on the expected shortage information. After constructing the mathematical model and solving the sensitivity analysis of the main parameters of the inventory system.
