碩士 === 國防大學理工學院 === 資訊工程碩士班 === 102 === This thesis aims to address the several problems in a distributed Joint Missile Defense System (JMDS) which includes weapon-target-assignment (WTA), dynamic simulation, distributed architecture, and the communication between firepowers and radars. We propose an objective function which pursues Facilities Protection Benefit (FPB), Intercept Benefit (IB) and Cost Benefit (CB). Also, we utilize improved rule-based greedy algorithm to complete WTA. For dynamic simulation, we apply Google Map to be a simulated battlefield and simulate some scenarios which could encounter in the real situations. We build a distributed architecture of the JFDS to simulate military operation units located at different place in battleground. These operation units can communicate each other. Through the technique of web-page, we can watch the process of engagement and review the result visually and intuitively so that commander can understand the quality of weapon-target-assignment result. At the simulation experiment, we design a scenario and record the result which includes the average quantity of our facility, the average execution time of the weapon-target-assignment, the average cost of firepower consumption, and the average percentage of target devastation. Regard to the experiment result, we can prove that it is better solution to solve WTA problem through the improved algorithm which we propose. At the same time, we also record the average utilization rate of firepower under the different algorithms. We can prove that it is better to enhance the utilization rate of all our deployed firepowers under the improved rule-based greedy algorithm. The better but high-cost firepower won’t be the first choice; instead, the others which equip middle-or-low level can also be exploited well. Finally, we can utilize the simulated result for deploying firepowers and adjusting position and quantity to find the best airspace defense management strategy.
