基于改进遗传算法的废旧家电回收网络模型研究

Analysis on recycling network model of obsolete household appliances based on Improved Genetic Algorithm

废旧家电作为可再生资源的一种,其体积大、回收价值高等特点引起了人们广泛关注,合理规划废旧家电回收网络是目前许多专家学者关注的问题。以上海某家废品回收公司为背景,深入研究废旧家电回收体系结构,建立居委会和交投站两层废旧家电回收网络结构模型,然后提出了改进遗传算法的数学模型并进行实例计算,最后对模型进行灵敏度分析从而获取较优的算法参数。

As one kind of recycling resources, obsolete household appliances induce popular attention among people because of their big volume and high recycling value. Planning reasonable recycling network of the obsolete household appliances attracts the eyes of many experts and researcher. Taking one recycling company in shanghai as background, the essay researches optimization of the recycling system of the obsolete household appliances, according to which the recycling network is set up by two layer, that is neighborhood committee and deliver station. Secondly, the improved genetic algorithm model is given and applies to example calculation. Finally, the essay analyzes sensitivity of the IGA （Improved Genetic Algorithm） model so as to get better algorithm parameters.
