This paper reviews the concepts of the product state models as an integrated database for Holonic Shop Floor Control. One of the requirements of agility is to be able to realise real-time control of manufacturing systems based on the actual state of the system and especially the state of its workpieces. The Product State Model (PSM) is an integrated object oriented database, which contains the dynamic data concerning the actual state of the workpieces during the manufacturing processing. It is integrated in the HoMuCS architecture by aggregating a PSM in each order holon. The paper outlines this as well as the general concepts of the PSM and the important parts of the HoMuCS system architecture. Finally the integration of a PSM is illustrated in a case study based on an industrial case at the Odense Steel Shipyard Ltd.
