【摘要】：针对输出质量特性服从正态分布的随机偏移单部件可修系统,研究了可变样本容量和控制线(Variable Sampling Size and Control Limits,VSSCL)均值控制图和预防维修策略联合经济设计问题。首先,构建了VSSCL均值控制图和预防维修策略联合经济设计的集成框架,揭示控制图和预防维修策略运行的耦合机制;然后,基于VSSCL均值控制图和系统状态特征参数,针对给出的集成框架确定了可能形成系统更新的四个维修事件的发生概率,并进一步利用更新过程理论和全概率公式,建立了VSSCL均值控制图和预防维修策略联合经济设计的平均单位时间成本最小决策模型;同时,针对具体实例,将构建的联合设计决策模型和独立设计决策模型进行比较分析,结果表明联合设计决策模型具有明显的经济优势;最后,利用回归正交试验设计方法对模型参数的灵敏度进行了分析。
[Abstract]:In this paper, the problem of combined economic design of variable sample size and variable Sampling Size and Control (VSSCL) mean control chart and preventive maintenance strategy is studied for a random offset single-unit repairable system with output quality characteristics from normal distribution. Firstly, an integrated framework of VSSCL mean control chart and preventive maintenance strategy is constructed to reveal the coupling mechanism between control chart and preventive maintenance strategy, and then, based on VSSCL mean control chart and system state characteristic parameters, The probability of the four maintenance events which may form the system update is determined for the given integration framework, and the renewal process theory and the full probability formula are further used. The minimum decision model of average unit time cost of combined economic design of VSSCL mean value control chart and preventive maintenance strategy is established, and the joint design decision model and independent design decision model are compared and analyzed. The results show that the joint design decision model has obvious economic advantages. Finally, the sensitivity of the model parameters is analyzed by using the regression orthogonal design method.
