Real-time task scheduling with fuzzy deadlines and processing times. (English) Zbl 0965.68005
Summary: A set of \(n\) independent and periodical tasks are considered. The processing times and the deadlines are described by fuzzy numbers. We try to find the optimal assignment of priorities not to miss deadlines. We manage the problem in two ways: first, we solve the problem by introducing the new cost functions; second, we solve the problem by using the ordering relations defined on fuzzy numbers. Examples with trapezoidal and triangular fuzzy numbers are provided.
