Slovak University of Technology Faculty of Material Science and Technology in Trnava CIM Introduction to CIM
Methodology for discrete-event simulation software selection • Realization in two phases • The first phase • Reduce selection to max. 10 products on the base of important criterion (K.O.) (red in tables) • The second phase • Detail evaluation of software packages on the base of the next weighted criterion
What does it mean CIM ? • Computer integrated manufacturing • Uniform definition does not exist! • Generally valid solution does not exist!
CIM • New philosophy of enterprise management. • The goal is the implementation of information technologies to all enterprise activities: • Increasing of labour productivity • Decreasing material and energy costs • Reduction of flow time • Increasing of capacity utilisation • Increasing of production quality
CIM is characterised: • Application independent database • Consistent chain of business processes • Short feedback • fast reacion on system changes
CIM • Usually CIM is understood as philosophy than tool in spite of CIM covers a lot of methods and tools. • CIM philosophy arose as answer to rapid development industry and computer technologies. • CIM does not represent only one software homogenous system, but more different software and interfaces for integration already installed systems.
Integration in CIM • The integration is key element of CIM • We discriminate • vertical integration – different function • horizontal integration – parts the same function
CIM • CIM (Computer Integrated Manufacturing) is understood as a model for continuous support of production and development by information technologies.
CIM - integration • Pod základným princípom integrácie rozumieme spojenie všetkých pracovných miest a strojov navzájom ako aj ich spojenie s plánovacími, dispozičnými, riadiacimi systémami, ktoré sú prepojené navzájom. Tieto spojenia sú zabezpečené administratívnymi, štruktúrnymi a technickými opatreniami. • Data integration is the second relevant attribute of CIM.
Integrated information architecture • The big companies ORACLE, SAP etc. Promote the idea of building the integrated information architecture. Its basic features are: • Building of integrated data model • Design of robust and flexible applications which are designed for complex integration of business processes • Usage of flexible and open standards for integration realization • Modular implementation which respects business processes

CIE • CIM CIE • CIE Computer Integrated Enterprise • CIE = CIM + CAO ? • CAO Computer Aided Office
CHIMComputer-Human Integrated Manufacturing • The reasons of man integration into new production structures: • A lot of activities is not possible to technically cover • Only human know to evaluate many situations • A lot of decision processes are too difficult for automation • Today approaches to flexible productions is looking for synergic effect in relationship integration human and computer
Doubts about CIM • The main weakness of CIM building are administrative • absence of longtime information strategy • Not filfilled expectations Underestimating of human factor • Incompatibility of software and hardware • Dilemma in usage of information systems
Dilemma in usage of information systems • Recording a lot of information • Deficit of information • Communication without paper • Big usage of paper („stack of paper“) • software and hardware price decreasing • High cost for operation and maintenance
Not fulfilled expectations • Isolated subsystems without required interconnection • Management also workers have not needed knowledge for new philosophy • The approaches to CIM building were too technical and concentrated on productivity only • The achievement of total automation (without human) is impossible
Information technologies • The term represents all technology which cover with information processing. • It means mainly organization, computer and telecommunication equipment but also software and its organization.
Computer science • Computer scienceis science about systematic information processing, especially about automated information processing by computers • Computer Science - Informatics
