چکیده

In this article we answer the complexity question of two dual criteria scheduling problems which had been open for a long time. Both problems are single machine scheduling problems and both have the number of tardy jobs as the primary criterion. However, the first problem has the total completion time and the second one has the total tardiness as the secondary criterion. We show that both problems are binary NP-hard.

Complexity of Single Machine HierarchicalSchedulingD

In this paper we deal with the dual criteria optimization, explore the complexity status of hierarchical scheduling on a single machine. Hierarchical optimization is a special case of dual criteria optimization, where the most important criterion is at its optimal value. We'll assume the complexity of hierarchical scheduling on a single machine. While doing this, we'll use the case of two crite...

An algorithm for multi-objective job shop scheduling problem

Scheduling for job shop is very important in both fields of production management and combinatorial op-timization. However, it is quite difficult to achieve an optimal solution to this problem with traditional opti-mization approaches owing to the high computational complexity. The combination of several optimization criteria induces additional complexity and new problems. In this paper, we pro...

Minimizing the Number of Tardy Jobs in the Single Machine Scheduling Problem under Bimodal Flexible and Periodic Availability Constraints

In single machine scheduling problems with availability constraints, machines are not available for one or more periods of time. In this paper, we consider a single machine scheduling problem with flexible and periodic availability constraints. In this problem, the maximum continuous working time for each machine increases in a stepwise manner with two different values allowed. Also, the durati...

Minimizing the maximum tardiness and makespan criteria in a job shop scheduling problem with sequence dependent setup times

The job shop scheduling problem (JSP) is one of the most difficult problems in traditional scheduling because any job consists of a set operations and also any operation processes by a machine. Whereas the operation is placed in the machine, it is essential to be considering setup times that the times strongly depend on the various sequencing of jobs on the machines. This research is developed ...

The Finite Horizon Economic Lot Scheduling in Flexible Flow Lines

This paper addresses the common cycle multi-product lot-scheduling problem in flexible flow lines (FFL) where the product demands are deterministic and constant over a finite planning horizon. Objective is minimizing the sum of setup costs, work-in-process and final products inventory holding costs per time unite while satisfying the demands without backlogging. This problem consists of a combi...
