摘要
本文针对动态环境下大规模协同设计主体资源评选问题,在将协同设计主体资源动态综合评选问题转化成间接排序问题的基础上,构造了基于LS-SVM的协同设计主体资源综合能力水平比较分类模型。并以此模型为基础,进一步采用对分法构造了协同设计主体资源动态综合评选模型。实验验证表明,该模型不仅实现了在动态环境下大规模资源按照综合能力强弱快速准确的排序,而且还解决了以往数学方法存在的主观性强、过学习、维数灾、局部最优等问题,对于实现协同设计主体资源的有效发现具有重要的现实意义。同时,该方法为同类型评选问题提供了一种有效的解决途径。
Based on the transforming the problem of the dynamic comprehensive evaluation for the collaborative design provider into the problem of the indirectly ranking, this paper presents a model of horizontal comparison classifying for the comprehensive ability of the collaborative design providers using the LS-SVM, and then brings forward a model of the dynamic comprehensive evaluation for the collaborative design providers based on the former model using the bisection method, aimed at the problem of choosing through evaluation of the large - scale collaborative design providers under the dynamic condition. The experiment proves that the model not only implements the ranking of the large-scale collaborative design providers reliably and rapidly according to the comprehensive ability under the dynamic condition, but also solves the shortages of traditional mathematic methods such as subjectivity, over-fitting, curse of dimensionality and local optimization. The model has important realistic significance for the valid finding of the collaborative design provider. Also, this method provides a valid solution to the same type problem of choosing through evaluation in other fields.
