【摘要】 在构建高速公路收费系统综合评价指标体系的基础上,提出了用遗传算法(GeneticAlgorithms,GAs)与BP网络相结合的混合算法来进行综合评价的模型,即先通过遗传算法优化初始权值,再用BP网络进行精确训练,使网络收敛速度加快和避免局部极小,从而保证模型评价值客观反映真实评价。更多还原

【Abstract】 On the basis of the comprehensive evaluation method of expressway tolling system, the authors present the model of the mixed algorithm of GAS(genetic algorithms) and BP(back-propagation) network for comprehensive evaluation, in order to accelerate the convergence and improve the performance and GAS is used to optimize the initial weight of network firstly, then the BP network is used to further precise training in this model, so that the evaluation objectively reflect the real situation.更多还原
