The importance of proper management of materials is highlighted by the fact that they account for substantial portions of project cost and time.Expert estimates and historical data analysis indicate that materials account for 50±60%of project costand control 80%of its schedule.Major projects are characterized by many items of di?erent nature,overlapped design and construction,and increased rate and degree of changes.These features have exposed and attenuated shortcomings of the traditional clerically-oriented pricefocused approach to managing project materials.Previous studies have identi?ed main symptoms and causes and illustrated the attendant need for signi?cant improvements and systematic approach.For instance,non-availability of items when needed on site is identi?ed as the major and most common and frequent cause of delays in projects and an integrated computer-based materials management system is concluded to produce 10±12%saving in labour cost.The situation is succinctly put in the form of a question reported to have been repeatedly asked by leaders in the industry;as quoted in Stukhart:``How do we achieve effective materials management?''

材料管理在整个工程成本和工期中占有相当大的比例,这也使得合适的材料管理变得尤为重要.专家预估与历史数据分析都显示,物料占整个工程成本的 50±60%,而且控制工期的80%.大型工程都有不同性质的物品,重叠设计和建筑以及不同的变化的程度和比率.这些特征暴露了传统的书记员式的注重价格的物料管理方式的一些弱点.早期研究已经诊断了主要症状和成因,并举例说明了方法改进和系统性的重要.例如,当工地需要时,物品的不可用性是延误工程的最常见的诱因,而一个基于计算机的集成型物料管理系统能够使劳动成本减少10±12%.这一状况被简化为一个问题,业内很多管理者都频繁提及.就像Stukhart所说：``如何对物料进行高效管理呢?''
