直觉模糊集在装备采购中的应用

The Application of Instinct Fuzzy Sets to Equipment Purchasing

在装备采购中,存在多个装备供应商可供选择,对供应商资格评价和准则定义的理论研究是供应商选择的关键问题。针对这一问题,基于直觉模糊集并加以改进,提出一种新的多属性决策综合评判模型,为装备采购决策者提供一定的定量分析依据,做出正确的决策,以及在招标中就供应商的选择提供具有参考价值的建议。运用此理论,使模糊多属性决策问题研究结果更合理、更科学。讨论供应商的评判问题,通过直觉模糊集理论,结合供应商选择问题,首先,构建改进型直觉模糊集决策矩阵,然后确定直觉模糊正理想解,再计算各备选方案到直觉模糊正理想解A+的矩离,最后按照综合评价指数K确定最佳供应商。算例分析表明了该方法的有效性和优越性。

There are several suppliers we can choose in purchasing equipment. The study of the theory in qualification judging and standard defining for suppliers is the key to choosing a supplier. Based on the instinct fuzzy set and the improvement on it, this paper presents a synthesis judging model of multi - attribute decision -making, which will provide a basis of quantitative analysis for the equipment purchase decision - makers and help them make a right decision, and also can offer some valuable advice on the problem of supplier choosing in the invite public bidding. The application of this theory makes the results of the synthesis judging model of multi - attribute decision -making become more reasonable and scientific. In a word, this paper discusses the problem of the supplier qualification judging based on the theory of the instinct fuzzy set, then gives an example of the supplier choosing, and the results indicate the validity and feasibility of the model.
