摘要: 机载公共设备的综合管理是机载系统发展的必然方向,为解决机载公共设备综合管理系统中任务分配问题,进行了任务划分.根据周期任务和非周期任务对系统风险系数的贡献不同,提出了两层任务分配策略;以单机风险系数均衡为目标函数,设计了基于蚁群算法的周期任务分配算法.对蚁群算法进行了模糊自适应参数调整的改进,仿真结果表明改进算法能够有效地使蚁群算法从局部最优点中逃脱,解决任务分配问题.

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