Abstract: It is to develop an indicator system of performance evaluation for land reclamation in oil & gas exploitation project by identifying the key factors that influence the performance of land reclamation of Oil & gas exploitation project.Methods employed include analytic hierarchy process and Triangular fuzzy numbers.By combining the two methods above,this paper proposes a triangular fuzzy AHP approach that allows both multi-criteria and simultaneous evaluation to evaluate the performance of land reclamation project.The proposed approach is capable of removing the ambiguity in evaluation by using the triangular fuzzy numbers as a pairwise comparison scale,which can derive the weights of factors and sub-factors.The results show that the approach can be an effective tool to evaluate the performance of land reclamation in oil & gas exploitation project and a reference for the performance evaluation of the similar land reclamation project in oil & gas exploitation project.
