Application of Gray Fuzzy Theory in the Post Evaluation of the Huaihe River Treatment Engineering

Chinese Huaihe River treatment engineering had made brilliant achievements which provided a reliable guarantee of social stability, development and prosperity of watershed economy. As a means of decision-making and management of construction project, the post evaluation of the project was an essential element of basic procedures of project management. Combined with the gray fuzzy evaluation method, project post evaluation on the Huaihe River engineering was conducted in this paper. The result showed that the gray fuzzy evaluation method could reduce the influence of subjective factors impacted on project post evaluation to some extent, and make the qualitative issues quantification possible.
