不确定情况下双寿命装备梯次使用问题建模及I-NSGA-Ⅲ求解

Modeling and I-NSGA-ⅢSolving of Echelon Usage of Dual-Life Equipment Under Uncertainty

在任务数量和消耗量不确定的情况下,针对由两种寿命指标衡量且其中一种无法被控制的装备梯次使用问题建模和求解方法进行了研究。构建不确定情况下双寿命装备梯次使用问题决策模型,提出以梯次均匀度、寿命匹配度和寿命利用率最大化为目标,使用I-NSGA-Ⅲ进行求解。采用改进的分段编码方式和算子,引入重复个体控制机制以提高种群多样性。当问题规模较大时,可以在较短的时间内搜索更大范围,验证了所提方法的可行性。

This paper studies the modeling and solving method of echelon usage problem of equipment measured by dual-life indexes and one of them cannot be controlled in the case of uncertain task quantity and consumption.The decision-making model of echelon usage problem of dual-life equipment under uncertainty is constructed.The maximization of the echelon uniformity index life matching index and life utilization index is taken as the objective.The I-NSGA-Ⅲis used to solve the problem.The improved segmented coding method and operators are adopted and the repeated individual control mechanism is introduced to improve the diversity of the population.When the scale of the problem is large the search of a larger range in a shorter time can be realized which verifies the feasibility of this method.
