Job-shop scheduling in a body shop
Journal of Scheduling, 2012We study a generalized job-shop problem called the body shop scheduling problem (BSSP). This problem arises from the industrial application of welding in a car body production line, where possible collisions between industrial robots have to be taken into account.

Solving Fuzzy Job-Shop Scheduling Problem Using DE Algorithm Improved by a Selection Mechanism
IEEE transactions on fuzzy systems, 2020The 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).

Abstract A periodic version of the Job Shop Problem is presented, in which each task has to be repeated at a given rate in identical conditions. Constraints arising from job sequences, machine capacities, limited size of buffers and transportation times between machines are considered and their modelization is explained.

Adaptive scheduling for assembly job shop with uncertain assembly times based on dual Q-learning
International Journal of Production Research, 2020To address the uncertainty of production environment in assembly job shop, in combination of the real-time feature of reinforcement learning, a dual Q-learning (D-Q) method is proposed to enhance the adaptability to environmental changes by self-learning

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,

In this paper, we present a timed model called Resources Allocation Timed Automata (RATA), expressing parallel behaviors in natural way and supporting at the same time explicit action duration and shared resources. We show how the classical job-shop scheduling problem can be modeled naturally in RATA model, we present also two algorithms for finding ...

Transfer-robot task scheduling in job shop
International Journal of Production Research, 2020This paper studies a simultaneous scheduling of production and material transfer in a job shop environment. The simultaneous scheduling approach has been recently adopted by warehouse operations, wherein transbots pick up jobs and deliver to pick ...

Abstract The paper defines batch or job shop production and reviews the functions of production planning and production control in a job shop manufacturing situation. It argues that the separation of planning and control has resulted in the artificial isolation of the sequencing problem in job shop research.

, 1992 The job shop scheduling problem is described as follows. Given are a set of jobs and a set of machines. Each machine can handle at most one job at a time. Each job consists of a chain of operations, each of which needs to be processed during an uninterrupted time period of a given length on a given machine.
