从生产率管理的含义出发，提出了工程项目生产率管理系统理论模型，研究了该模型的运行机制，并在其指导下，结合工程项目管理的实际，构造了生产率测度与管理实用模型（ＭＰＩ）。最后结合算例对ＭＰＩ模型的应用进行了分析，表明该模型简便有效，适用于工程项目现场，其计算结果为承包商进行生产率降低损失索赔的辨识、分析，以及生产率控制与改善提供了有力的依据。 Based on the meaning of productivity management, a theoretical model of engineering project productivity management system is put forward. The operating mechanism of the project is studied. Under the guidance of the project management, a practical model of productivity measurement and management (MPI) is constructed. Finally, an example is given to analyze the application of the MPI model, which shows that the model is simple and effective and can be applied to the project site. The calculation results provide the contractor with the identification, analysis and productivity control of productivity loss and improvement in accordance with.
