基于TOPSIS法的农机维修方案评估研究

Research on the Assessment of Agricultural Machinery Maintenance Scheme Based on TOPSIS

科学地评估农机维修企业的维修方案,对提高客户服务质量及维修企业实现利润最大具有重要的现实意义。为此,基于效用函数及逼近理想点法(TOPSIS,Technique for Order Preference by Similarity to Ideal Solution)理论原理,建立了农机维修方案评估模型。该模型通过比较各方案与次理想解及次负理想解的距离,采用效用函数来求解距离的效用,从而筛选出更加符合实际的维修方案。实例结果验证表明,该算法是有效和可行的。

It is very important to scientifically evaluate the maintenance enterprise scheme of agricultural machinery which enhance the quality of client service and the profit of maintenance enterprise and.On the basis of the theory of Technique for Order Preference by Similarity to Ideal Solution(TOPSIS) theory,the paper builds the model of the evaluation of agricultural maintenance scheme,and then comes up separately compares the distance between each schemes with hypo-ideal explanation and minus hypo-ideal explanation and uses utility function to count utility of the distance consequently arranges orders of each scheme and chooses the scheme.Finally,according to the counting of a example to prove that the method is effective and rational.
