Comparison and Study of Multiple Evaluation Methods for Dynamic Characteristics of AC Contactor

摘要

This paper evaluated the dynamic characteristic of a single product by means of different methods based on the study of AC contactor dynamic response in the same research team.Triangle and interval membership functions were used respectively in four methods, including fuzzy analytic hierarchy process (AHP), fuzzy comprehensive evaluation combined with FAHP, both subjective-objective and objective fuzzy entropy weight methods.It is concluded by comparison that the sorting through fuzzy entropy method using interval membership function is more consistent than others.The analysis provides a theoretical basis for rational selection of decision-making methods to AC contactor dynamic characteristic.
