Quality control of feedback machining system with finite source and standbys

Abstract

This paper provides the quality control policy to improve the performance and the effectiveness of the machining system with standbys (spares) from the viewpoint of the queuing theory. The unit in the system is called a customer to whom the service should be rendered. An inspector is used to control the inspection process of the serviced unit. Under steady-state situation and the feedback concept, we obtained some performance measures and the probability when the system is empty or it has n units. Some important special cases and some analysis about the economic optimisation model with illustrative numerical examples are performed.
