Advanced Metaheuristic Method for Decision-Making in a Dynamic Job Shop Scheduling Environment

open access: yesMathematics, 2021
As a well-known NP-hard problem, the dynamic job shop scheduling problem has significant practical value, so this paper proposes an Improved Heuristic Kalman Algorithm to solve this problem.

A linear programming-based method for job shop scheduling [PDF]

open access: yes, 2012
We present a decomposition heuristic for a large class of job shop scheduling problems. This heuristic utilizes information from the linear programming formulation of the associated optimal timing problem to solve subproblems, can be used for any ...

A Two-Phase Iterative Mathematical Programming-Based Heuristic for a Flexible Job Shop Scheduling Problem with Transportation

open access: yesApplied Sciences, 2023
In a flexible job shop problem with transportation (FJSPT), a typical flexible manufacturing system comprises transporters that pick up and deliver jobs for processing at flexible job shops.

Manufacturing Control in Job Shop Environments with Reinforcement Learning

open access: yesInternational Conference on Agents and Artificial Intelligence, 2021
: Computing solutions to job shop problems is a particularly challenging task due to the computational hardness of the underlying optimization problem as well as the often dynamic nature of given environments.

Evolving Scheduling Heuristics via Genetic Programming With Feature Selection in Dynamic Flexible Job-Shop Scheduling

open access: yesIEEE Transactions on Cybernetics, 2020
Dynamic flexible job-shop scheduling (DFJSS) is a challenging combinational optimization problem that takes the dynamic environment into account. Genetic programming hyperheuristics (GPHH) have been widely used to evolve scheduling heuristics for job ...

A MILP model for an extended version of the Flexible Job Shop Problem [PDF]

open access: yes, 2014
A MILP model for an extended version of the Flexible Job Shop Scheduling problem is proposed. The extension allows the precedences between operations of a job to be given by an arbitrary directed acyclic graph rather than a linear order.

A vibrant crossbreed social spider optimization with genetic algorithm tactic for flexible job shop scheduling problem

open access: yesMeasurement + Control, 2020
Job shop scheduling is one of the major issues in which the scheduling process is associated with the real-time manufacturing industry. A flexible job shop scheduling problem is one of the most important issues among the hardest combinatorial advancement

Performance Assessment of Dynamic Flexible Assembly Job Shop Control Methods

open access: yesIEEE Access, 2020
Developments of information technology provide a foundation for implementing shop floor control in high variety production environments. A dynamic flexible assembly job shop is abstracted from a mold industry, we suggest the use of a hierarchical ...

Job-shop scheduling with limited capacity buffers [PDF]

open access: yes, 2006
In this paper we investigate job-shop problems where limited capacity buffers to store jobs in non-processing periods are present. In such a problem setting, after finishing processing on a machine, a job either directly has to be processed on the ...
