design of computer integrated manufacturing system for irankhodro auto industry

computer-integrated manufacturing (cim), technologies are presented as solutions tomanufacturing organizations, which need to perform well in all customer-related dimensionssimultaneously. in the literature, cim technologies providing such benefits as more frequentproduction changes, reduced inventory level, improved ability of producing complex parts with ahigh degree of accuracy and repeatability, considerable savings in scrap and rework, lowermanufacturing lead-times. in this paper a general model and architecture of cim for irankhodroauto industry is designed. also for each function or subsystem a model is design in cimenvironment. the model has three rings. first ring including three sections: data management,data representation and communication. second ring is decision support system (dss) includingthree sections: dss for design, dss for manufacturing and dss for management. third ringincluding all functional area including marketing, design, process planning, manufacturing,production planning and control, quality control, warehouse, management, finance etc. also fordesign of cim system seven levels is considered including: at business level, at facility level, atshop floor level, at cell level, at workstation level, at machine level, at sensor level. also cimmodel of iran is based on the seven layers of standard namely open system interconnection (osi)defined by iso. irankhodro auto industry briefly introduce and its barrier and problem forimplementation of cim is discussed. the main objective of this paper is design of a cim forirankhodro automotive industry in iran.
