摘要 题目： 大型生产企业采购物流DSS研究与应用 专业： 物流管理 导师： ×× 教授 随着科技化，信息化的发展，企业作为市场的主体，始终是以利润最大化为目的，节约成本支出。通常情况下，由于采购部门往往能控制40%—50%的金额量，减少材料成本对一个公司的成本控制有着举足轻重的影响。另外，如果在这一方面进行控制，可以以现有的人员，常常不需要额外的支出或投资就能降低材料成本。 近些年来，随着采购信息管理系统的逐步普及，越来越多的企业在采购成本控制上取得了长足的进步。但随着企业间竞争的日益激烈，利用更先进的科学工具来进行内部采购控制逐步成为更大的需求。 决策支持系统（Decision Support System，简称DSS）是辅助决策者通过数学模型知识，以人机交互式进行半结构化或非结构化决策的计算机系统。它是管理信息系统()向更高一级发展而产生的先进信息管理系统。它为决策者提供分析问题、建立模型、模拟决策过程和方案的环境，调用各种信息资源和分析工具，帮助决策者提高决策水平和质量。Abstract Topic: Study and Application of DSS for Procurement Logistics of Large scale Production Enterprise Major: Logistics Management Supervisor: ×× Professor Along with the development of information technology, the market, the enterprise as main body, always is for the purpose of profit maximization, save costs. Normally, due to the procurement department often can control the amount of 40-50%, it can reduce the cost of materials to a companys cost control has significant influence. Additionally, if in this aspect, can control by the existing staff, often do not need additional expenses or investment can reduce the material cost. In recent years, with the purchasing information management system gradually popular, more and more enterprises in the purchasing cost control have made good progress. But with the increasingly fierce competition between enterprises, use more advanced scientific tools for internal procurement control gradually into a greater demand. Decision Support systems (DSS) was aided by mathematical model of knowledge, policymakers in man-machine interactive for half an institution or unstructured decision-making of the computer System. It is the management information system (MIS) to a higher level of development and advanced management information system. It provided analysis, model and simulation of the decision-making process and the scheme of information resources, environment and analysis tools, and help to improve the level and quality decision makers. This article mainly expounds the DSS system in
