研究了实践中常见的四种预防工作组合类型,即定时维修、功能检测、使用检查及检查与定时维修的组合策略,以单位时间维修费用最小为目标建立了多部件故障预防工作的组合优化模型.在此基础上,提出了两个故障预防工作的组合优化算法,并给出了计算示例以说明模型和算法的性能. This paper studies the four types of prevention work combinations that are common in practice, namely, the combination strategy of timing maintenance, function testing, using inspection and inspection and regular maintenance, and sets up a combined optimization model of multi-component fault prevention work with the goal of minimizing the maintenance cost per unit time Based on this, two combinatorial optimization algorithms for fault prevention are proposed, and an example of calculation is given to illustrate the performance of the model and algorithm.
