Development of an Integrated Model for Maintenance Planning and Statistical Process Control

An integrated model of maintenance planning and statistical process control is developed for a production process. The process has two operational states including an in-control state and an out-of-control state, where the process failure mechanism is supposed as a general continuous distribution with non-decreasing failure rate. Based on the information obtained from the control chart, three types of maintenance actions may be implemented on the process. The integrated model optimally determines the parameters of the control chart and maintenance actions so that the expected cost per time unit is minimized. To evaluate the performance of the integrated model, a stand-alone model is developed. In the stand-alone model, only maintenance planning is considered. Finally, a real case study is presented to clarify the performances of these models.
