生产车间安全管理状况的区间数模糊综合评价方法研究

针对生产车间安全管理状况评价的多维多层次性和不确定性,运用区间数模糊综合评价方法对其进行综合评价.该方法基于层次分析和模糊综合评价的基本原理,对于单因素权重、综合评价权重、各指标评分和评价集中评价等级水平均采用区间数,以使评价更符合客观实际.研究了区间数层次分析综合排序权重的确定,建立了区间数模糊综合评价模型.在得出生产车间安全管理状况综合评价区间数得分之后,引入了区间数排序可能度和区间数符合度的概念,提出了由综合评价结果得分区间数确定评价水平等级的方法.通过实例分析,验证了该评价方法的可行性.

Study on the fuzzy integrate evaluating method of interval nmnber on the workshop safety management

This paper is inclined to introduce the authors' study on a new method for evaluating the production safety in a workshop based on the multi-dimensional and multi-level factors including a lot of uncertainties. Since the safety management of the workshop production involve so many factors and uncertainties, it is necessary to use the interval number fuzzy integrated evaluation, which is based on the basic principles of Analytic Hierarchy Progress and fuzzy integrated evaluation. According to the method, all the single factors used for evaluation weight, all the index scores and the evaluation grades are taken as the form of interval number so as to make the evaluating process more practical. The paper has also studied how to fix the evaluation weight of the interval number hierarchy and worked out a model of the interval number fuzzy integrated evaluation. When the evaluation is done in accordance with the given model, the final score of the workshop production safety management parameters would be calculated. Then the ranking possibility degree and the suitability degree of interval number could be introduced and the method of fixing on the grade of the workshop safety management status could be put forward in conformity with the final score. The application of the method in a case study proves the method valuable.
