✦ Synopsis

We examine a small lot production setting in which a machine may go out of control and begin producing defective units. Traditionally, managers have had to rely upon observations of the quality of the output to determine whether the machine is in or out of control. However, with advances in technology such as vibration analysis, it is increasingly possible to obtain much more accurate information about the state of the machine. In this paper, we model and analyze a deteriorating machine in order to gain insight into the conditions under which investments in such technology are most beneficial.

Scheduling deteriorating jobs is an area of research which has attracted much attention recently. In this paper the problem of single machine scheduling, where the values of jobs remaining after processing deteriorate over time, is presented. A branch and bound method is developed, which, using the
