为解决在应急条件下的装备器材供应过程中由于器材需求点时间窗变动而产生的干扰问题,在对需求点时间窗变动扰动辨识和度量的基础上,制定了扰动恢复策略,构建了基于虚拟资源点的需求点时间窗变动扰动恢复模型;为寻求最优解,设计了基于轮盘赌选择的改进变邻域搜索算法。通过数值试验对模型和算法的有效性进行了验证。 In order to solve the interference problem caused by the time window change of the equipment requirement during the emergency equipment supply, based on the identification and measurement of the disturbances of the time window of the demand point, a disturbance recovery strategy was formulated and a virtual Resource point demand window time-window perturbation recovery model. In order to find the optimal solution, an improved variable neighborhood search algorithm based on roulette selection is designed. The validity of the model and algorithm is verified by numerical experiments.
