Two key tools for process management are statistical process control (SPC) and maintenance management (MM). An economic model can be created when they are coordinated. This paper studied the exponentially weighted moving average (EWMA) control chart of SPC and planned maintenance, as well comparing the optimal values of an X-bar control chart and an EWMA control chart. A mathematical model was developed to analyze the cost computed from the EWMA control chart. This was used to find the optimal values of variable parameters (n*,h*,L*,k*) that minimized the hourly cost.
