Choosing an Appropriate Factorial System through the Modern and Outmoded System by Two Approaches ANP AHP-FUZZY

Today, by introducing the factorial modern systems to the construction industry of the country, it is not easy to make a decision in order to use these modern systems together with the outmoded and conventional systems .Regarding the unique traits in each of these systems, and the special conditions of each project, it is possible that each of these systems to have a priority over the factorial systems prevailing in the country. Thus, it was made an effort to choose the most appropriate factorial system through the modern and outmoded systems in the country using the multi criteria making decision methods, ANP and AHP-FUZZY, and regarding some of the important criteria in choosing the type of the factorial system such as dead load, saving energy, performance facility, etc .finally, light steel frame (LSF) system has been chosen as the most appropriate selection through the ones under study.
