Abstract:In order to better control the equipment maitenance quality by computer, this paper studies the theory of group AHP, (Analytic Hierarchy Process), introduces the Euclidean distance theory, improves it by the distance scale, analyzes and defines the equipment maintenance process module, sets up the quality evaluation index system, obtains the equipment maintenance quality evaluation method based on the improving group AHP at last. Finally, it gives an example that the method carries on the concrete application through a certain type equipment. Analysis of application results shows that this method can get a more scientific, accurate evaluation results than general method, and more operable in computer application. It provides a useful method for equipment maintenance quality evaluation and control.
