中文摘要：

不同于制造业库存管理,建设项目的物料库存受施工现场的限制,既要求不能一次订购超出现场库存能力的数量,又要求建材供应不能出现间歇。为满足施工现场库存管理这一要求,文章采用系统动力学仿真的方法,从施工承包商的视角,以钢材为例,构建了施工现场钢材库存模型。通过模型对不同采购预警值进行了对比分析,得出了合理的预警值。并对支付延迟可能产生的影响,给出了相应的应对策略,保证了施工的正常进行。最后,将模型在中国2010年上海世博会某场馆工程建设中进行了检验。

英文摘要：

Unlike the inventory management of manufacturing,the materials inventory of construction projects are limited by the construction site that the material’s order cannot be out of the inventory capacity and neither the supply can be intermittent.To meet the requirement of inventory management in the construction site,this paper adopts the system dynamics simulation method,takes the steel as an example,constructs an steel inventory model in construction site from the perspective of the construction contractor.The paper also obtains the reasonable value according to the comparative analysis of different procurement of early warning value in the model and puts forward to the corresponding coping strategies to ensure the normal construction.Finally,the paper takes a pavilion in Shanghai Expo 2010 as an example to verify the feasibility of the model.
