چکیده

In this paper, we address the scheduling model with discretely compressible release dates, where processing any job with a compressed release date incurs a corresponding compression cost. We consider the following problem: scheduling with discretely compressible release dates to minimize the sum of makespan plus total compression cost. We show its NP-hardness, and design an approximation algorithm with worst-case performance ratio 2.

A fuzzy mixed-integer goal programming model for a parallel machine scheduling problem with sequence-dependent setup times and release dates

This paper presents a new mixed-integer goal programming (MIGP) model for a parallel machine scheduling problem with sequence-dependent setup times and release dates. Two objectives are considered in the model to minimize the total weighted flow time and the total weighted tardiness simultaneously. Due to the com-plexity of the above model and uncertainty involved in real-world scheduling probl...

Scheduling with Discretely Compressible Processing Times to Minimize Makespan

In the classical scheduling problems, it is always assumed that the processing time of a job is fixed. In this paper, we address the scheduling with discretely compressible processing times, i.e., the possible processing time of a job can only have finitely many possibilities. Of course, choosing to process any job with a compressed processing time incurs a compression cost. We consider the sin...

Minimizing Total Weighted Tardiness with Drop Dead Dates in Single Machine Scheduling Problem

  This paper deals with minimization of tardiness in single machine scheduling problem when each job has two different due-dates i.e. ordinary due-date and drop dead date. The drop dead date is the date in which jobs’ weights rise sharply or the customer cancels the order. A linear programming formulation is developed for the problem and since the problem is known to be NP-hard, three heuristic...

Scheduling interval orders with release dates and deadlines

We study the problem of scheduling unit-length tasks with release dates and deadlines subject to precedence constraints and unit communication delays. Two polynomial-time algorithms are de ned: one constructs schedules for graphs with uniform release dates, the other for graphs with arbitrary release dates. They have a special structure: unlike most scheduling algorithms, they do not consider i...

The preemptive resource-constrained project scheduling problem subject to due dates and preemption penalties: An integer programming approach

Extensive research has been devoted to resource constrained project scheduling problem. However, little attention has been paid to problems where a certain time penalty must be incurred if activity preemption is allowed. In this paper, we consider the project scheduling problem of minimizing the total cost subject to resource constraints, earliness-tardiness penalties and preemption penalties, ...
