Fuzzy tree model for evaluating employee performance evaluation system and Selection evaluation system for branch of University of West Azarbaijan

This study evaluates the fuzzy tree model to evaluate employee performance evaluation systemand Selection evaluation system for the University of West Azarbaijan units has been done.The study staff units are the University of West Azarbaijan province. In this discourse, in order to prevent the effects of the unfavorable appraisal system in west Azerbaijan Branches of Islamic Azad University, it has been intended to present a model of fuzzy tree for investigating the methods of the performance appraisal of the employees. on the basis of this model, the right performance appraisal method for each sector will be chosen. First, the researcher recognize the effective factors in identifyiny the method of the performance appraisal, then by using these factors the performance oppraisal of employees are investigated. In this case, the viewpoints of professors and the experts of human resources management are being used. By using the obtained knowledge from the experts of humsn resources management, knowledge base is created and by using knowledge base and algorithm and fuzzy sets, the model of fuzzy tree is offered. Then by distributing the guestionnaire, the values of each variable (the effective factorse in identifying the performance appraisal method) for each sector are identified. In the end, by using these obtained values, the priority of the methods of performance appraisal for each sector in identified. At the next step, by using the fuzzy multi-criterion decision making, the researcher identifies the priority of selecting the appraisal methods for each of these sectors on the basis of decision value
