CIM

Introduction to CIM

Slovak University of TechnologyFaculty of Material Science and Technology in Trnava

Methodology for discrete-event simulation software selection

Realization in two phasesThe 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 functionhorizontal 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

1. 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.

2. 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

Integrated support of business processes

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 long time information strategyNot filfilled expectations Underestimating of

human factor Incompatibility of software and hardwareDilemma 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 science is science about systematic information processing, especially about automated information processing by computers
