Preface
Enterprises are the basic cells of national economy, the ultimate force to promote economic and social development, and also the decisive factor for a strong country and a prosperous nation. There are a lot of theories about how to improve the market competitiveness and economic and social benefits of enterprises. They have their own characteristics and made due contributions to the economic and social development.
In the process of enterprise operation and management, with the development of science and technology and the improvement of the application level of network technology, the manual work mode and management mode have been unable to adapt to the development speed of modern society. Building management information system to meet the needs of enterprise modern management has become the future development direction of improving the work efficiency and standardized management of all departments. The core essence of enterprise material management is to use network technology and computer technology to integrate enterprise procurement and production resources, reduce operating costs, improve enterprise production efficiency, and ultimately achieve maximum value.
In recent years, with the economic and social development of our country and the introduction of a series of material supply management systems, the level of material management is getting higher and higher. However, in today’s prosperous society, the supply of materials exceeds the demand, and the economic benefits of enterprises are relatively good, the material procurement is big, the price is high or low, the production is guaranteed blindly, resulting in the material cost greatly increased, the reserve fund sharply increased, resulting in excessive reserves and extreme waste. At the time of market operation and economic benefit decline, facing the gradual improvement of operation awareness of enterprises in all walks of life, if we do not calculate and analyze, nor fully face material saving and thrifty, nor control the purchase volume to reduce the purchase cost, and generate the maximum benefit with the minimum investment, the enterprise will face the situation of operating difficulties until the loss.
In order to realize the information collection and processing, information resource sharing and decision-making assistant management between enterprises and different departments within enterprises, it is necessary to establish enterprise material management system. Its goal is to realize enterprise information network, information resource, management modernization and scientific decision-making.

前 言
企业是国民经济的基本细胞，是推动经济社会发展的终极力量，也是一个国家强大、民族兴旺的决定性因素。围绕提高企业市场竞争力和经济社会效益的各种理论浩如烟海， 各种主张层出不穷， 它们各具特色并对经济社会发展做出了应有贡献。
在企业运营管理过程中，随着科技的发展和网络技术应用水平的提高，使得手工工作方式和管理模式已经不能适应现代社会的发展速度，而构建管理信息系统来满足企业现代化管理的需要，成为提高各部门工作效率及规范化管理的未来发展方向。企业物资管理的核心是利用网络技术和计算机技术整合企业采购和生产资源，降低经营成本，提高企业生产效率，最终实现最大化的价值。
近年来，随着我国经济社会发展和一系列物资供应管理制度的出台，物资管理水平越来越高。但是，在社会繁荣，物资供过于求，企业经济效益相对较好的今天，物资采购大手大脚，价格高低不管，一味地保证生产，致使材料成本大大增加，储备资金急剧上升，造成过度储备和极度浪费。在市场运转，经济效益滑坡之时，面对各行各业企业运营意识的逐步提高，今天我们再不算账分析，再不全面对材料节约节俭，再不控制采购量降低采购成本，以最小的投入产生最大的效益的话，企业将面临经营困难，直至亏损的局面。
为了实现企业与企业之间、企业内部不同部门之间的信息收集与处理、信息资源共享以及决策辅助的管理，需要建立企业物资管理系统。其目标是实现企业信息网络化、信息资源化、管理现代化以及决策科学化。
