Choose the Optimal Method of Building Construction Using Multi-Criteria Decision Shannon Entropy and Fuzzy and Gray VIKOR

Housing is one of the major needs. The use of new and new technologies to increase the speed of construction, improve quality, increase earthquake resistance, increase the useful life of buildings is more than ever before. In this paper, four building methods Including LSF, LCF, 3D-PANEL and PRCS, 12 criteria for timely delivery of credit, ease of implementation, need for expert workforce, availability of consumable materials, control and supervision in the process of implementation, useful life, cost, quality Maintenance, energy saving, reducing dead load, increasing floors, compliance with regulations that, from the point of view of contractors, employers, And project consultants. These criteria have been selected using the Delphi method from among the selected criteria, and the fuzzy and gray vikor method has been used to rank building methods, to collect information from seven companies The contractor, two consulting companies and a number of professors have been used to obtain information. Regarding the ranking differences of the methods of construction in both fuzzy and gray vikor methods, for the final ranking of the ranking method, which includes the mean rating method, the Breda method and the Copland method, was used. For the results obtained The best way to build PRCS is through the LSF and 3D-PANEL methods, and finally the ICF method.
