Abstract
This paper deals with a real-time scheduling method of HMS (Holonic Manufacturing System). A real-time scheduling process based on the estimation of future status of the HMS have been proposed and applied to the real-time scheduling problems of the HMS in the previous report. Only one holon estimates the future status of HMS to determine the next machining schedule by using a simulation, in the previous method. New systematic methods for the individual holons are proposed, in the paper, to make all the holons determine the next machining schedules based on the future status of HMS estimated by simulaton, aiming at improving the previous methods. The effectiveness of the proposed methods are verified through the case studies.
