The airborne utility management system is the inevitable development trend of airborne system. The tasks of the airborne utility management system (UMS) were partitioned for solving the task assignment problem. The two-level task allocation strategy of cycle task and non-cycle task was put forward because their contributions are different for the risk coefficient of system. Taking the balance of risk coefficient among the computers as the goal function, the cycle task allocation algorithm based on the ant colony optimization algorithm was designed. The ant colony algorithm was improved by fuzzy-adaptive parameter regulation. The simulation results show that the improved algorithm can efficiently make it escaped from the local extremum and resolve the UMS task assignment problem of utility management system.
