Manufacturing planning and control systems (MPCSs, for short) are an essentialelement for supply chain processes today. However, there are few researches whichinclude planning information systems in supply chain models and optimize the wholestructure holistically in spite of the social importance of MPCSs for supply chainmanagement. At present, we do not have any ideas even about process behaviorwhen organizations which have MPCSs are linked in a supply chain. To clarifyfundamental properties of supply chain structures including planning informationsystems are tasks of big challenges as well as pressing urgencies. While planninginformation systems and practical activities have been told individually in manyresearches, they should be dealt holistically as a system. This research aims at theingegration of planning systems and practical activities to optimize whole supplychain structures. Actual supply chain processes have million considerable parameters,and they interact each other. It is too complex to deal, so we simplified supplychain processes focusing on interaction between material flow and information flow inthis paper. Firstly we suggested the supply chain process model, and then dynamicproperties of the process are shown. Analyses of the behavior implies managementcapability and limits of the MPCSs. Furthermore, a way of optimization for thesupply chain structure and the effects are shown.
