Evaluating the supplier cooperative design ability using a novel support vector machine algorithm

The supplier´s cooperative design enables the enterprise to use supplier´s technical ability fully, reduce the time of product coming into the market, improve quality, and reduce cost. Aiming at the problem of how to evaluate the supplier cooperative design ability (SCDA), this paper constructs the evaluating indices system that is composed of product concept and functional design support ability, product structure design and project support ability, and the process design and project support ability. To evaluate the SCDA scientifically and accurately, this paper proposes the multi-level classification evaluating model based on improved support vector machine (SVM), which uses the SVM classification combination in series and introduces the type weight factor and sample weight factor. The model not only solves the shortcomings of small sample, high dimension, nonlinear and local minima in the traditional model, but solves the wrong classification question caused by the number imbalance of training samples and data interference. The SCDA evaluating results of 12 enterprises in Hebei Province show that the model is simple and feasible, improve the evaluating accuracy and efficiency.
