Study on Optimal Path for Multiple-Constraint Military Transportation Based on Dijkstra Algorithm

Wang Jun;Jia Bin;Dong Lifeng;Ji Shuai;Shi Yulei;Postgraduate Training Brigade,Military Transportation University;National Emergenecy Transportation Equipment Engineering Research Center,Military Transportation University;  
Traditional Dijkstra algorithm usually obtains the optimal path in accordance with the ascending order of path lengths. It is based on a single weight value. Combining the needs of military transportation path planning,taking into consideration of multiple constraints of distance,road grade and security,the paper expands the traditional Dijkstra algorithm to obtain the optimal path under multiple-constraint condition. And by limiting a rectangular search area,it narrows road network scale,reduces the number of nodes,and improves the efficiency of the algorithm.
