生产率管理系统模型及其应用研究

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。

A Productivity Management System Model and Its Application

A theoretical model for the productivity estimate and management system (PEMS) of engineering items is proposed based on the concept of productivity management with its operational mechanism described. Meanwhile, combined with the practice of engineering items, a practical model for the measure, prediction and improvement (MPI) of productivity is built under the guidance of the proposed theoretical model. The analysis of the application of the MPI model into an engineering example shows that the model is characterized by simplicity and effectiveness, and be suitable for the spot application of engineering items. The calculation result provides a basis for contractors to recognize and analyze the construction claims for losses resulted from the productivity decrease, and to control and improve the productivity.
