A Hazardous Inspection Model.

Abstract

This paper considers a hazardous inspection model. One is given a device which operates throughout a number of periods and which in each period may be subject to failure. Failure of the device is directly observable. Prior to failure the device will enter a state in which it is functioning, but in an impaired manner. This state can be detected only by performing an inspection. Once the machine is known to be in the impaired state, appropriate action may be taken to prolong the remaining life of the device. In this respect inspection is valuable. However the act of inspecting the device when it is not impaired may itself cause the device to become impaired. In this respect inspection is hazardous. This paper deals with the determination of inspection policies which maximize the expected lifetime of the device.
