In this paper, a survey of scheduling problems with due windows is presented. The due window of a job is a generalization of the classical due date and it is a time interval in which this job should be finished. If the job is completed before or after the due window, it incurs an earliness or a tardiness penalty. A review of an extensive literature concerning problems with various models of given...
We have studied problems of scheduling n unit-time jobs on m identical parallel processors, in which for each job a distinct due window is given in advance. If a job is completed within its due window, then it incurs no penalty. Otherwise, it incurs a job-dependent earliness or tardiness cost. The objective is to find a job schedule such that the total weighted earliness and tardiness, maximum weighted...
In the paper we investigate four single processor scheduling problems, which deal with the process of the negotia-tion between a producer and a customer about delivery time of final products. This process is modeled by a due window, which is a generalization of well known classical due date and describes a time interval, in which a job should be finished. Due window assignment is a new approach, which...
The paper deals with a single machine scheduling problem with job processing times dependent on continuously-divisible resource, e.g. gas, power, energy, raw materials, catalyzer, financial outlay. Ready and delivery times are also given for each job. The problem is to find a schedule of jobs and resource allocation that minimize the time by which all jobs are delivered. Genetic approach, using some...
