โœฆ Synopsis

For most of scheduling problems, jobs' processing times and due-dates are treated as certain values, but that is not proper to all actual situations. Processing times are not constant because of measurement errors in the data sets for deciding them and/or human actions in the manufacturing process. However, we may be permitted to exceed due-dates slightly. In this paper, we propose a model dealing with uncertain processing times and ยฏexible due-dates in consideration of real situations. Assuming the times and due-dates to be fuzzy numbers, and deยฎning a fuzzy tardiness for a job's due-date, we design to minimize the number of tardy jobs in our problem formulation.

In this paper, we examine the characteristic features of multi-objective scheduling problems formulated with the concept of fuzzy due-date. By computer simulations, we show that various scheduling criteria can be expressed by modifying the shape of membership functions of fuzzy due-dates. We also sh

The paper deals with periodical task scheduling. The tasks are described by fuzzy due dates and fuzzy execution times. The goal of scheduling is to find an optimal assignment of priorities such that the satisfaction associated with due dates and execution times be minimized. The paper shows how the

A set of n independent and periodical tasks are considered. The processing times and the deadlines are described by fuzzy numbers. We try to รฟnd the optimal assignment of priorities not to miss deadlines. We manage the problem in two ways: รฟrst, we solve the problem by introducing the new cost funct
