چکیده انگلیسی
While many control charts have been developed for monitoring the time interval (T) between the occurrences of an event; many other charts are employed to examine the magnitude (X) of the event. This article presents a single statistical process control (SPC) chart (called the rate chart) for simultaneously monitoring the time interval T and magnitude X based on the ratio between X and T. The new chart is more effective than an individual T chart, individual X chart, or a combined T&X chart for detecting the out-of-control status of the event, especially for detecting downward shifts (sparse occurrence and/or small magnitude). More profound is that, comparing with an individual T or X chart, the rate chart performs more uniformly for detecting both T shift and X shift, as well as the joint shift in T and X. The rate chart has demonstrated its potential not only for manufacturing systems, but also for non-manufacturing sectors such as supply chains, office administration and health care industry.
