Quality evaluation for construction machinery using fuzzy analytic hierarchy process

In an implementation process from design,assembly to usage for construction machinery,the evaluation criteria are contained amongst each process stage.By comparing and analyzing these criteria,it is useful for decision-makers to focus on improving product feasibility and economics.In this respect,a quality-related mechanical evaluation criterion system is established.In details,a fuzzy analytic hierarchy process model,which synthesizes fuzzy theory and analytic hierarchy process,are proposed and investigated via an assignment method for the membership and weighting.Through the quality evaluation for a specific construction machinery,it is found from the evaluation results that this approach possesses its practicality and generality.
