We consider multiprocessor scheduling to minimize makespan. Each job has a given processing time and in addition, a subset of machines associated with it, also called its processing set. Each job has to be assigned to one machine in its set, thus contributing to the load of this machine. We...

We consider a production model with two facilities sharing a resource during a time horizon consisting of a number of time periods. Cumulative production levels at the ends of consecutive periods are linked with constraints of a general form. This allows us to give different interpretations...
