One of the basic problems in time sharing systems and multiprocessing operating systems is to find an optimal schedule for a given set of tasks. In this paper we analyze the complexity of a restricted version of the general preemptive scheduling problem. We introduce a scheduling model that guarantees that preemption of a task is only possible after a reasonable part of the task has been processed. It turns out that this problem isNP-hard in general, but very good approximation algorithms can be found and special cases can be solved exactly in polynomial time.
