TLDR
In this paper, the authors deal with an assembly job shop scheduling problem considering two phases of control: order review/release (ORR) and dispatching rules and evaluate the ability of different combinations of ORR-dispatching rules in optimising due date and flow time related performance.Abstract:
This paper deals with an assembly job shop scheduling problem considering two phases of control: order review/release (ORR) and dispatching rules. Dispatching rules have been intensively used in earlier job shop research. Such rules determine the processing sequence of jobs waiting in the queues of corresponding machines. In recent years, ORR emerges as another option for job shop control and has received increasing attention. Such control determines when to release jobs to the shop floor. Different ORR mechanisms have been devised and are reported to bring several advantages such as reduced inventory cost of early finished orders, controlled and balanced shop load levels and shorter order flow time. Previous studies on ORR often assume a simplified job shop without assembly operations, while this research applies ORR to an assembly job shop. The aim of this research is to evaluate the ability of different combinations of ORR-dispatching rules in optimising due date and flow time related performance measu...read more

Multi-objective optimisation in flexible assembly job shop scheduling using a distributed ant colony system
TL;DR: A distributed ant colony system is proposed to solve the production scheduling problem in a flexible manufacturing system with two adjacent working areas and outperforms most of the other methods for the tested problems, making it a valuable and competitive approach for solving practical production scheduling problems.

A lean-based ORR system for non-repetitive manufacturing
TL;DR: In this article, the authors argue that job shop designed ORR systems are not the best ones for non-repetitive production and that a significant number of production systems are better modelled as flow shops, rather than as job shops.

Theory and practice of load-oriented manufacturing control
TL;DR: Load-oriented manufacturing control is a new solution for job shops and its successful implementation in a plastic leaves factory as mentioned in this paper, where the idea is to limit and balance work-in-process inventory on a level as low as possible in order to accomplish a high workcentre utilization as well as a rapid and in-time flow of orders.

TL;DR: In this article, the authors examined the ORR function and its impact on the operation of the shop floor and found that ORR does not always reduce the total time spent in the system.
