ABSTRACT

Aiming at the problem that the comprehensive evaluation method of crane hoisting mechanism system based on AHP needs many people to participate in and the evaluation method of crane hoisting mechanism system lacks timeliness caused by complicated process, a comprehensive evaluation method of crane hoisting mechanism system based on grey correlation and AHP is proposed. Firstly, the relative weights of the bottom elements of the hierarchical model of the hoisting mechanism system with respect to the top evaluation indexes are obtained by the analytic hierarchy process (AHP). Then, the membership degree of the bottom elements with respect to the state level is obtained by the grey correlation method. Finally, the calculated values are combined to obtain the final state of the hoisting mechanism system of the crane. The method achieves the rapid evaluation of the state grade of the crane hoisting mechanism system with the participation of a small number of people, and achieves the goal of rapid evaluation.
