We have studied here the real-time production scheduling problem for m
ultiple-part-type flow shops. The system under consideration consists
of many machines and produces many product types. Each part goes throu
gh the system following a pre-defined routeing and may visit each mach
ine at most once. We consider three classes of activities: operations,
failures or repairs, and starvation or blockage. The scheduling objec
tives are to keep the actual production close to the demand and to red
uce the work-in-process inventory and cycle time. A three-level hierar
chical production control model is developed to regulate production fo
r the manufacturing systems. The control policy specifies how to react
to machine failures. It also tells how to allocate limited system cap
acity among all the part types. It utilizes the material and the space
in the storage buffers to alleviate the propagation of a failure to o
ther machines in the system.
