摘要
针对运输的最小时间路径问题,采用模糊数表示车辆在各路段的运行时间,建立模糊最小时间路径模型.该模型不仅得到两节点间的最小模糊时间值,而且得到最小时间路径;利用模糊结构元处理模糊数的运算,简化了模型的运算.实例表明:该模型有效地解决了交通网络中任意两节点间的最小时间路径问题.
Aiming at the problem of determining the minimum-time path of transportation, this paper built a minimum-time path model by using fuzzy number to express the running time of each path. This model can not only get the minimum fuzzy time value between two points, but can also gradually get the minimum-time path. By dealing with the fuzzy number operation with the fuzzy structured element, the model is simplified. Examples show that the model can effectively solve the minimum-time path between any two nodes in the transport network.
