Abstract:

To effectively promote the coordinated development of each subsystem of hydropower engineering program and improve the synergy degree of the whole program as well as its individual parts, a synergy degree evaluation model based on entropy weight and TOPSIS is proposed aiming at the strong subjectivity of common evaluation methods. A hydropower engineering program synergy degree evaluation index system composed of six subsystems including information, resources, culture, target, environment, and organizational management and 19 secondary indexes is established. The entropy weight method is used to determine the weight of each index while TOPSIS is adopted to calculate the relative closeness of each subsystem and the holistic closeness of whole program in the four stages of initiation, planning, execution and control, completion. The empirical analysis of a hydropower engineering program shows that the overall synergy degree of the program is stable but low, which is in line with the actual situation.
