Risk analysis of project groups based on improved fuzzy comprehensive evaluation

In order to increase their market competitiveness, construction companies have started to undertake multiple projects simultaneously. Project management is not suitable for managing multiple projects. In order to achieve benefits that cannot be obtained from a single project, construction companies have started to form project groups and use project group management methods to manage them. The project group management model not only brings more benefits to construction enterprises, but also increases many problems. Taking the project group of a certain construction enterprise as an example, a hierarchical structure model is established from four aspects: information, environment, management, and cooperation. 12 secondary indicators are selected, and an improved Analytic Hierarchy Process (AHP) three scale method is used to establish a judgment matrix. The weight vector is calculated and fuzzy comprehensive evaluation is carried out. The results indicate that the fuzzy comprehensive evaluation of the project group of the construction enterprise is safe.
