Strategy research on supply chain inventory control under stochastic demand

Abstract

Taken into account by multiple suppliers,a distribution center consisted of two supply chain system in the market demand for the random case of many species inventory problem.By identifying the relationship between each variable to the smallest expected loss distribution center for the objective function,the creation of a mixed-integer nonlinear programming model,while the use of multi-function solution of conditional extremum approach to solving the problem model,and finally gave the a numerical example to further interpretation of the solution.Thus enriched the market immediately in the face of demand for many varieties of inventory control strategy studies.

考慮了由多個供應商、一個配送中心組成的二級供應鏈系統在市場需求為隨機情況下的多品種庫存問題。通過確定各變量之間的關系,以配送中心損失期望值最小為目標函數,建立了一個混合整數非線性規劃模型;利用求解多元函數條件極值的辦法來求解該問題模型;最后給出了一個算例進一步詮釋了該解法,從而豐富了在面對市場為隨即需求下的多品種庫存控制策略的研究工作
