Multiple-subject Involved Evaluation Method And Its Application In Environmental Performance Evaluation Of Iron And Steel Enterprises

Group evaluation theory and method has been widely used in the management activities of economic management,political,military and other fields,and it is playing an important role.Currently,the research on the group evaluation has been being fruitful,and with the development of economy,the large group evaluation activities become more frequent and the number of evaluators gradually increases,and it often requires many types of evaluators to participate in the evaluation process.Based on this,considering the evaluation participants of different types as different evaluation subjects,this paper proposed a multiple-subject involved comprehensive evaluation method.The main work is as follows:(1)The multiple-subject involved weighting method was proposed and the weighting process of group evaluation was detailed.And based on the steps of rank relation analysis method,the subjects are involved in the selection of indexes,the rank of indexes,and the determination of relative importance between indexes.And in order to determine the index weight,the paper proposed index selection method based on the modified frequency,the solving method of the density weighted vector and the method of influence coefficient of each subject.(2)The multiple-subject involved goal-oriented comprehensive evaluation method was proposed.At first,the influence coefficient of each subject to different index were determined according to each subject's judgment,and then the target of each index was obtained;secondly,the realization level of objectives and other related concepts were proposed to obtain the information aggregation results related to the realization level of objectives.The goal-oriented comprehensive evaluation method can promote the objects under the guidance of goals,and the "efforts" and "contribution" will be fully reflected by realization level of objectives and other related information integration results.Finally,the paper put forward four forms of time value factor with the objects' time preference to determine the weight of time.(3)The environmental performance of three domestic iron and steel enterprises was evaluated with the multiple-subject involved goal-oriented comprehensive evaluation method and the results were analyzed,and at the same time the policy suggestions were proposed.Finally,the main research results were summarized and the prospect of the research was given.
