摘要
由于战时作战强度、战场环境变化不确定性,导致战损或故障装备的产生无法提前获知,从而战时装备维修机构受领维修任务进行装备维修作业成为一个占线问题。采用占线单服务排序理论对该问题进行建模,定义了战时装备维修收益函数,设计了一种改进的基于单位平均收益的单服务维修策略,推断了其有效竞争在概率意义上为2/η(η>>1,η是与不同维修任务类型发生概率相关的统计量),为战时装备维修策略选择提供了新思路和可行做法。
For uncertain wartime environment , it is difficult to get the information about damaged or broken-down equipment in advance , that makes maintenance task be a online question .We model the question with online single scheduling theory , design an effectiveness function and present an improved single service strategy based on unit average benevolent .We further put forward and prove that the competitive ratio of the strategy is 2/η（η＆gt;＆gt;1,ηis a probably statistic variable with maintenance task ）.We present a new plan method and feasible way for wartime maintenance strategy .
