Abstract: For the facility location problem of operations equipment support, a locating decision-making model of operations equipment support is proposed. The model decision-making target model is the minimum support-delayed time of the equipment system, and influence factors are considered including the operational task facility effect on repair capabilities of facility location, equipment technical faults, and battle damage. A two-phase heuristics algorithm using location and decision-service-relation, neighborhood search, and genetic algorithm are used. The decision-making target is acquired through Monte Carlo simulation. An example is used to verify the models and the effectuality of the algorithm, and it is demonstrated that the mission conditions have a significant influence on the operations equipment support facility location.
