Flexible Assembly Job Shop Scheduling Based on Tabu Search
نویسندگان
چکیده
Flexible assembly job shop scheduling has been proved to be an NP-hard problem. To reduce the complexity, it is always divided into 2 sub-problems: routing sub-problem and sequencing sub-problem. In this paper, in order to develop a solution with high accuracy, we propose a method that can deal with these two sub-problems concurrently. Tabu search, one of the meta-heuristics, is adopted. Some experiments are made to seek the best way to exchange the routes & sequences of work (operation) pairs in order to improve the result of schedule. Also some experiments of how to make a tabu list to identify the repetitive trials on the same work pairs are made too. The effect of our algorithm on decreasing total delay behind due time is confirmed.

Solving the flexible job shop problem by hybrid metaheuristics-based multiagent model
The flexible job shop scheduling problem (FJSP) is a generalization of the classical job shop scheduling problem that allows to process operations on one machine out of a set of alternative machines. The FJSP is an NP-hard problem consisting of two sub-problems, which are the assignment and the scheduling problems. In this paper, we propose how to solve the FJSP by hybrid metaheuristics-based c...

متن کاملMulti-Agent Approach Based on Tabu Search for the Flexible Job Shop Scheduling Problem
This paper proposes a Multi-agent approach based on a tabu search method for solving the flexible Job Shop scheduling problem. The characteristic of the latter problem is that one or several machines can process one operation so that its processing time depends on the machine used. Such a generalization of the classical problem makes it more and more difficult to solve. The objective is to mini...
