Adaptive production scheduling system based on agent

摘要

In order to improve the responsiveness to changes and uncertainties around production activity, we should have the agent model which allows us to uniformly model and design the total system including production and planning resource and related information exchanged among resources. There are two types of the agent in this model. One is a Service Agents that offers some processing functions. The other is a Mobile Agent that moves among Service Agents. A manufacturing resource is modeled as one of the Service Agents since it provides manufacturing functions. On the other hand, each lot or production instruction information controlling production progress can be model as one of the Mobile Agents. We develop a production scheduling system based on this model. In this system, each work center detects the production fluctuations by monitoring the status of internal production resources such as machine tools and buffers. Detecting a fluctuation, the work center determines the necessary measures by exchanging production information among other work centers and divisions.
