Abstract

In this paper, a new elevator operation reliability evaluation model based on the combination of Gray Relational Analysis (GRA) and Analytic Hierarchy Process (AHP) is proposed. In order to further overcome the shortage of indicators of equal rights and the lack of expert assignment via the original gray relational analysis method, AHP is used in this paper to determine the weight of each indicator in the proposed model, then GRA is used to get all indicators' gray relational degree between their current state and optimal state. The gray relational matrix is established and a quantitative assessment of elevator risk is achieved in the model. Finally, an example is used to show that the accuracy and feasibility of the proposed model.
