二维产品二维预防性维修间隔期优化研究

An Optimization Research on Two-Dimensional Preventive Maintenance Preventive Maintenance Intervals of Two-Dimensional Product

摘要:

针对故障受日历时间与使用时间共同影响的二维产品,传统的一维预防性维修已不能满足实际需求,鉴于此,本文创新性的提出了二维预防性维修的概念,以日历时间与使用时间对二维产品进行维修决策。首先建立二维产品故障率函数表达式,对二维预防性维修的过程进行具体的分析,然后以单位时间费用最小为约束目标,建立了无限使用期二维预防性维修模型,提出了最佳二维预防性维修间隔期,并通过实例对比分析了该模型的适用性与有效性,最后对未来的二维维修提出了展望。

Abstract:

For the failures of two-dimensional product effected by the calendar time and usage time, traditional one-dimensional preventive maintenance can’t meet the actual demand, therefor, this paper proposes the concept of two-dimensional preventive maintenance innovatively, makes decision for two-dimensional product through calendar time and usage time. First we establish failure rate function expression of two-dimensional product and analyze the process of two-dimensional preventive maintenance in detail, after propose a model of two-dimensional preventive maintenance to minimize the consumer’s cost per unit of time, and analyze the model’s the applicability and the validity through examples, then derive optimal two-dimensional preventive maintenance interval, the last we give a brief discussion of future research area about two-dimensional maintenance.
