A Multi-Stage Modelling Approche for Allocation of Defense Resources to Invading Targets

Weapon target allocation (WTA) is a command and control main components.In this process, the critical          time-based decisions often is made under uncertainty.In this paper attempt has been made to propose a realistic approach to WTA problem. We consider a multi-stage weapon target allocation with multiple criteria including: Minimizing the expected total value of surviving targets, minimizing the military resource costs and minimizing the allocation risks. In the following study to develop a more realistic weapon target allocation model, we have tried to bring almost all ignored constraints such scarcity of weapons, technological, atmospheric/geographical (e.g. terrain) and structural limitations into account. Finally Non-dominated Sorting Genetic Algorithm-II (NSGA-II) has been used for solving multi-objective WTA problem and a Pareto optimal front for the model is depicted. Comparison of the calculated solutions (from the point of quality and speed of calculation) with those provided with expert commanders, suggests that the modelling and solving method have been successfully designed and match the application greatly.
