Refinement of Time
We introduce a mathematical model of the timed behaviour of components with streams as input and output using a hierarchy of timing concepts. We distinguish non-timed streams, dis...

Minimizing total busy time in parallel scheduling with application to optical networks
—We consider a scheduling problem in which a bounded number of jobs can be processed simultaneously by a single machine. The input is a set of n jobs J = {J1, . . . , Jn}. Each j...
