Study On GIS Based Marching Command And Control System For Force Delivery

Rapid and efficient force delivery forms the top decisive factor for the army to perform military drills and to tackle the major emergency incidence. The military action of the force delivery should be taken within the shortest time, the least loss and the lowest risk, which relies on aspects like route distance, marching speed and risks of natural environment and enemy circumstances. It causes the continuous change of its structure characteristics and functions, which in turn leads to the change of the military traffic network. It makes the road network dynamic and increases the uncertainty of the force delivery. In this sense, the thesis proposes the GIS-based dispatch system of the force delivery. The system can have a real-time command over the traffic stream of the force delivery, and upgrade our army's efficiency in force delivery and intelligence level.According to the practical application requirement of the construction of the force delivery system, the thesis designs a echelon-traffic-flow-targeting and GIS-based system scheme and general framework of traffic command and control system for force delivery. The geographic information technology, Compass Navigation Satellite technology and CDMA communication technology are also applied into the system. Besides, it explores the two concerned key technologies of the echelon army's map matching and improved-genetic-algorithm-based route planning.Firstly, According to the characteristics of echelon army, the thesis proposes the map matching technology targeting many road conditions. Fully considering the integrity and continuity of the marching echelon, the topological characteristic of the actual road networks, the echelon length, and the projected distance and azimuth of the echelon's locating point, the technology can have a precise match between the marching echelon and the road. It solves the problem of locating and tracking of the marching echelon on the electronic map. The experiment demonstrates that not only can it be applied into different road sections, but also it guarantees the real-time property and accuracy of the echelon's locating.Secondly, based on the accurate locating of the military marching echelon, its characteristics of route planning, and the 6 typical road limitations, this thesis improves the traditional genetic algorithm. Choosing the appropriate encoding mechanism and adaptive crossover probability and mutation probability, the author adopts the improved genetic algorithm based on the optimization of multi-objective, in order to optimize the marching route. The experiment demonstrates that it increases the search efficiency and the convergence rate, producing a good route planning result.In addition, the thesis also designs the dispatching system of the force delivery. By integrating the dispatch system and the geographic information system, the earlier extensive manual dispatch is improved, being accurate, automated and intelligent. The current research, to some extent, lays foundation for the force delivery ability in the army.
