Scheduling the General Job-Shop

Management Science, 1985
A family of algorithms is described for finding optimum schedules for job-shops. The algorithms are of a branch and bound type but have a complete schedule associated with each node of the search tree. Branching from nodes is based on important conflicts in the schedule. Some results are provided.

Job Shop Scheduling

1997
The job shop scheduling problem (JSP) is a resource allocation problem where the resources are called machines. The problem involves finding an assignment (schedule) for a set of jobs to the machines so that the jobs can be completed “optimally.” Each job may consist of several tasks, and each task must be processed on a particular machine. Furthermore,

Real-Time Scheduling for Dynamic Partial-No-Wait Multiobjective Flexible Job Shop by Deep Reinforcement Learning

IEEE Transactions on Automation Science and Engineering, 2022
In modern discrete flexible manufacturing systems, dynamic disturbances frequently occur in real time and each job may contain several special operations in partial-no-wait constraint due to technological requirements.

Solving Fuzzy Job-Shop Scheduling Problem Using DE Algorithm Improved by a Selection Mechanism

IEEE transactions on fuzzy systems, 2020
The emergence of fuzzy sets makes job-shop scheduling problem (JSSP) become better aligned with the reality. This article addresses the JSSP with fuzzy execution time and fuzzy completion time (FJSSP).

Scheduling job shops with uncertainties [PDF]

Proceedings of the 36th IEEE Conference on Decision and Control, 2002
Effective management of production uncertainties is becoming critical in the era of "time-based competition". The consideration of uncertainties, however, is difficult because of the combinatorial nature of the problem as well as the probabilistic nature of uncertain factors.

Survey on Genetic Programming and Machine Learning Techniques for Heuristic Design in Job Shop Scheduling

IEEE Transactions on Evolutionary Computation
Job shop scheduling (JSS) is a process of optimizing the use of limited resources to improve the production efficiency. JSS has a wide range of applications, such as order picking in the warehouse and vaccine delivery scheduling under a pandemic. In real-

Large-Scale Dynamic Scheduling for Flexible Job-Shop With Random Arrivals of New Jobs by Hierarchical Reinforcement Learning

IEEE Transactions on Industrial Informatics
As the intelligent manufacturing paradigm evolves, it is urgent to design a near real-time decision-making framework for handling the uncertainty and complexity of production line control.

Real-time scheduling simulation optimisation of job shop in a production-logistics collaborative environment

International Journal of Production Research, 2022
In a complex and dynamic job shop containing logistics factor, schedule needs to be generated rapidly, so the real-time scheduling method is more suitable for such scenario.

Scheduling job shops with delays

Proceedings. 1987 IEEE International Conference on Robotics and Automation, 1991
In this paper, the presence of delay in a job shop is addressed. We show that delay is an important consideration in many manufacturing systems that are modeled as continuous flow processes. A scheduling policy for a job shop with delays is then derived using theoretical arguments and heuristics.
