The Structure of Engineering Project Evaluation System: Model and Analysis

From the system theory perspective, the paper constructs a structure model of engineering project evaluation system that provides an analysis framework to project evaluation. The model analysis shows that engineering project evaluation system is a complex system. There are many feedback loops between the evaluation subject, the implement subject, evaluation criteria and evaluation results. The interaction between evaluation subject and project implement subject plays a decisive role in the function of project evaluation system. There will be a vicious feedback circle that affects project evaluation effect if project implement subject have effect on evaluation subject.
