An Integrated Group Decision Analysis Framework to Evaluate the 3P Projects in Intuitionistic Fuzzy Setting

In today's world, one of the most efficient ways to build large projects and infrastructure is related to public-private partnership (3P) projects. This method is based on the partnership between the public and private sectors and exempts the government from providing financial, human and equipment resources along with taking risks in the construction of the project. In this method, after construction and operation, the project is handed over to governments and made available to the public. In this article, following the removal of obstacles to production and development projects, we used 3P approach in the face of intuitive fuzzy uncertainty to bring management decisions closer to the outside world. Meanwhile, an integrated group decision analysis based on intuitionistic fuzzy utility degree method and intuitionistic fuzzy preference evaluation technique is tailored to compute the experts’ weights and criteria importance, respectively. Then, a novel ranking approach based on positive/negative ideal solutions and relative closeness coefficient under intuitionistic fuzzy set theory is proposed to solve the 3P urban development project selection problem. Finally, in order to evaluate the proposed method and determine its efficiency for use in large projects, a case study of urban development is used, and comparisons are made between previous methods and the proposed method.
