Abstract

In order to meet the real-time and visualization requirements in discrete manufacturing process, obtain accurate information of personnel, machine and other related resources in the production process in time, and make a quick response, this paper proposes a job-shop real-time scheduling model based on RFID. By reasonably arranging RFID tags and RFID readers in job-shop, the production information of the job-shop can be obtained in a timely and accurate manner. Then, the machining capabilities of the machines in the jobshop are calculated through a machine evaluation model, the results of which is considered as the input of the next job-shop scheduling model. An improved ant colony algorithm (ACA) is employed to solve it. Finally, a case is simulated and studied showing the applicability of the proposed models and methods.
