基于供应链管理的供需双方经济批量模型实证分析

本文认为,供应链中的每个节点既是后一节点的供应商,又是前一节点的顾客,供需关系始终贯穿于整个供应链。传统经济批量模型中,订货商仅从自身利益出发追求成本最低的订货批量,这对供应商而言并非最优,供应商和订货商是矛盾对立的。在现代供应链管理中,供需双方应是一种战略合作伙伴关系,合作博弈的结果理应达到双赢。因此,为在竞争中取胜,应形成以顾客为中心的供应链管理,一方面,供应商应提高生产系统的柔性,对顾客需求作出快速反应;另一方面,供应商应与订货商建立战略联盟,追求优化、高效的供应链管理。本文建立的订货商的经济批量模型、订货商已作决策条件下的供应商最优生产批量模型以及供需双方合作博弈条件下的价格折扣模型可以优化供应链管理,促使供需双方达到双赢,从而实现供应链效益的最大化。

An Empirical Analysis on Economic Size-lot Model between Vendors and Buyers Based in Supply Chain Management

In order to realize the target of the Maximum overall value of supply chain management,the author brings forward that the study on supply and demand is the most important and most fundamental part of supply chain management;and concisely narrated the decision-making model for both sellers and buyers and decision process;and built the economic lot size model for indentor and the optimum production lot models for suppliers under condition of decision on ordering goods;then studied the price discount model based on the game of cooperation between vendors and buyers,so as to optimize supply chain to mutual benefits for both parties.Finally,the author analyzes the models by demonstration.
