It follows the need of the market and the client . the goal of erp is to implement enterprises " resources optimizing configuration and remove all the invalid work and resources . it can achieve the integration of information stream, material stream, capital stream, value stream and operation stream 企业资源计划(erp)是一种20世纪90年代初期以市场和客户需求为导向,以实行企业内外资源优化配置,消除生产经营过程中一切无效的劳动和资源,实现信息流、物流、资金流、价值流和业务流的有机集成和提高客户满意度为目标,以计划与控制为主线,以网络和信息技术为平台,面向供应链的先进管理思想。
On the premise of the study about the developing of xi'an city's water supply and the great variety in water supply and the shortage of water resource, aiming for the furthest benefit from the configuration of water supply source of xi'an city and facilitating it's development, this paper analyzed the characteristics of water supply sources and its changing quantity, the rising demand of water in city and the situation about water supply source, studied the problem about water supply via a variety sources, raised the principles of optimized configuration of variety sources, built the model of water demand forecasting and optimized configuration, studied the configured plan and its managing pattern 本论文从研究西安市城市供水的发展过程入手,重点分析了城市供水水水源和城市用水需求增长的变化特点,在城市供水状况相当长的时期内将表现为供大于求的重大变化和西安市资源性缺水的现实没有改变的背景下,以实现最大限度地发挥城市供水系统的作用合理配置缄市供水水源,促进西安社会经济的持续、快速、健康发展的总体目标,研究了运用多水源科学合理的供水问题。分析了西安市城市供水水源状况、用水量变化特点以及各水平年需水量,提出了多水源优化调配的原则,建立了需水预测模型与优化调配模型,初步研究了西安市城市供水水源合理配置方案和相应的管理模式。
