【Abstract】 In urban fire fighting, it’s important to find the best path for dispatching fire services. The minimum path is not always the best one, since there are many factors which affect the traffic. To find the optimal path of dispatch, an integrated parameter is introduced as a weight to modify the Dijkstra Arithmetic. The integrated parameter is determined by many experiential functions, reflecting the effects of road conditions, traffic, and different periods of a day respectively. By comparing the results of the Dijkstra Arithmetic and that of the modified one, it is found that the latter seems to be more reasonable. Based on the modified optimal path arithmetic, a module for urban fire decision making is built on a Geographical Information System (GIS).更多还原
