一种基于遗传算法的多模式多标准路径规划方法
路径规划 多模式 多标准 遗传算法
2014/4/9
单一路径评价标准难以满足日益多样化的出行路径规划需求。多标准路径规划成为公众出行服务的研究热点。然而，多标准路径规划本质上是具有NP特性的多标准决策问题，且涉及多种交通出行模式。多个不同标准的权重设置将直接影响路径规划结果。因此，如何科学合理地设置不同标准的权重成为多标准路径规划中的技术瓶颈。本文提出了一种适应多模式交通网络环境的多标准路径规划方法，借鉴遗传算法在求解多标准优化问题中的优势，将其扩...
2004年以来中国农业和农村发展政策逐渐转型，给农村发展带来新的机遇，也为相关发展决策与规划提出了新的现实需求。村域是中国农村社会经济活动的基本单元，承载着农村家庭联产、乡村企业生产、农民日常生活、农村社区发展等生产、生活行为。本文以“背景分析—机理剖析—水平评价—病症诊断—病因分析—路径谋划”为主线，构建基于模糊层次分析等方法的参与式村域发展综合诊断技术方法体系，并以黄淮海传统农区一个典型村域为...
