针对电子侦察卫星在执行初始侦察计划过程中各种扰动发生的情况,分析研究各类扰动的特点,建立资源和任务之间的优先映射关系,引入扰动测度来度量动态调度规划结果与原规划结果之间的变化程度;以最大化完成任务优先级之和,以及扰动发生后对原始计划调整最小为目标,建立了具有两级优化目标的动态约束满足模型,提出动态调度的启发式信息计算方法及基于启发式信息的动态调度方法,通过实例仿真,表明该扰动测度和链式效应影响计算方法,以及模型和算法的可行性,对解决实际问题具有一定理论意义和现实意义。
Aiming at the situation of various kinds of disturbances during the initial reconnaissance plan of electronic reconnaissance satellite, this paper analyzes the characteristics of all kinds of disturbances, establishes the priority mapping relationship between resources and tasks, and introduces the disturbance measure to measure the results of dynamic dispatch and original planning The dynamic constraint satisfaction model with two levels of optimization objectives is established with the goal of maximizing the sum of task priorities and minimizing the adjustment of the original plan after the disturbance and the heuristic information calculation method of dynamic scheduling is proposed And dynamic scheduling method based on heuristic information. The simulation results show that the method of calculating the disturbance measure and the influence of chain effect, as well as the feasibility of the model and algorithm, have certain theoretical and practical significance for solving practical problems.
