The one-machine just-in-time scheduling problem with preemption

This paper investigates thenotion of preemption in scheduling,with earliness and tardiness penalties. Starting from the observation that the classical cost model where penalties only depend on completion times does not capture the just-in-time philosophy, we introduce a new model where the earliness costs depend on the start times of the jobs. To solve this problem, we propose an efficient repr...

The Preemptive Just-in-time Scheduling Problem in a Flow Shop Scheduling System

Flow shop scheduling problem has a wide application in the manufacturing and has attracted much attention in academic fields. From other point, on time delivery of products and services is a major necessity of companies’ todays; early and tardy delivery times will result additional cost such as holding or penalty costs.  In this paper, just-in-time (JIT) flow shop scheduling problem with preemp...

Efficient Algorithms for Just-In-Time Scheduling on a Batch Processing Machine

Just-in-time scheduling problem on a single batch processing machine is investigated in this research. Batch processing machines can process more than one job simultaneously and are widely used in semi-conductor industries. Due to the requirements of just-in-time strategy, minimization of total earliness and tardiness penalties is considered as the criterion. It is an acceptable criterion for b...

Preemption in Single Machine Earliness/Tardiness Scheduling

We consider a single machine earliness/tardiness scheduling problem with general weights, ready times and due dates. Using completion time information obtained from the optimal solution to a preemptive relaxation, we generate feasible solutions to the original non-preemptive problem. We report extensive computational results demonstrating the speed and effectiveness of this approach.
