Abstract: Evaluation of the execution of contracts is important in engineering construction supervision. This paper begins with an investigation on the features of engineering contracts, followed by an analysis of the engineering contracts using analytic hierarchy process (AHP). Then, a fuzzymathematical model is builtfor evaluating engineering construction contracts, with a method and a practical model for the construction evaluation and hierarchical evaluation of engineering contracts presented. Finally, the operation significance of the model proposed in this paper is verified with an example.
