Journal Article 2021 04 24 Social responsibility and risk are some essential issues in projects to consider. Knowing the type of ‎risk in each project and its impact is an important and significant issue in choosing a project or ‎participating in tenders. Considering the increasing growth of urban communities and the need to ‎carry out tasks, and the rising standard of living, trying to carry out projects with advanced ‎technologies seems to be a necessity that requires modern and continuous planning to implement ‎the relevant matters. These plans aim to increase quality and reduce costs due to the high level of ‎demand. In the present study, a fuzzy multi-objective mathematical model has been designed to ‎prioritize projects, minimize the risks involved in implementing each project, maximize profit ‎margins, maximize project costs, and maximize jobs created by the project. Finally, an example ‎appropriate to real-world problems is designed and examined to ensure the correct operation of ‎the proposed model. https://ijnaa.semnan.ac.ir/article_5190_5f0a30516fb4894d77ad4d5ee92e1edc.pdf
