Evaluation of framed building types based on the combination of fuzzy AHP and fuzzy MOORA methods

Mankind has been using different kind of materials to build shelters and after then more specific structures throughout the history. If the stone is accepted as a primitive construction material; wood, concrete and steel has spread to the construction history. However, from both of the supply and demand view, it is possible to say that defining the best solution to the construction necessities and constraints is vastly ambiguous. In other words, making decision with respect to infinite parameters is an important task. The level of uncertainty in the optimality based definition of framed building types is relatively high and need to be carefully analyzed. Therefore, in order to select a proper construction technique, combination of fuzzy AHP (analytic hierarchy process) and evaluation based on fuzzy MOORA (multi objective optimization by ratio analysis) has proposed a new useful method, in which FAHP is used for calculating priority weight of criteria and the MOORA is implemented for obtaining the final ranking of construction techniques. In addition, for expressing the applicability of the offered model, it is supported by a case study. In the rating of framed building types; cost, performance, time, fire, corrosion, esthetics and recycling is considered as important factors. As a result, this model is easy to understand and simple to implement in various areas. Also, this method is applicable for the choosing of proper alternatives in different selection problems.
