基于系统动力学的装配式建筑成本管理研究

Research on Cost Management of Prefabricated Buildings Based on System Dynamics

装配式建筑因其施工周期短、节能环保等优点而成为当今建筑业发展的必然趋势。由于我国装配式仍处于起步阶段,施工规模小、技术落后、工程成本较高,制约了其发展。所以,对装配式建筑项目成本的分析与研究是非常有必要的。文章以系统动力学为核心,首先确定了系统边界,找出主要的成本影响因素,剖析其内在原因和作用机理;其次,建立和验证成本管理的动态模型,并通过仿真模拟,得出降低装配式建筑成本的合理建议。

Prefabricated buildings have become an inevitable trend in the development of the construction industry today due to their advantages such as short construction period and energy conservation.However,as prefabrication in China is still in its infancy,with a small construction scale,backward technology,and relatively high project costs,its development is constrained.Therefore,it is necessary to analyze and study the cost of prefabricated building projects.This paper,with system dynamics as its core,first defines the system boundary,identifies the main cost influencing factors,and analyzes their inherent reasons and operating mechanisms.Secondly,it establishes and validates dynamic models of cost management and,through simulation,provides reasonable suggestions for reducing the cost of prefabricated buildings.
