Economic design of integrated time-between-events chart system with independent quality characteristics

This article presents the economic design of the integrated control chart system consisting of several individual time-between-events (TBE) charts for monitoring time between successive events in different process stages in a multistage manufacturing system. The design of the integrated chart system has been illustrated through an example. The proposed control chart system is easy to understand and operate, and thus the floor operators can utilize and understand it as easily as for the traditional system.
