• Introduction to CIM

2
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

3
What does it mean CIM ?

• Computer integrated manufacturing
• Uniform definition does not exist!
• Generally valid solution does not exist!

4
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

5
CIM is characterised

• Application independent database
• Consistent chain of business processes
• Short feedback
• fast reacion on system changes

6
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.

7
Integration in CIM

• The integration is key element of CIM
• We discriminate
• vertical integration different function
• horizontal integration parts the same function

8
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,
   dispozicnými, riadiacimi systémami, ktoré sú
   prepojené navzájom. Tieto spojenia sú zabezpecené
   administratívnymi, štruktúrnymi a technickými
   opatreniami.
2. Data integration is the second relevant attribute
   of CIM.

10
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

The main features of modern enterprise

• Constantly reduction and improvement of business
  processes
• Immediate eliminates of all forms of waste
• Constantly trends monitoring
• Continual changes

14
The principles of enterprise development

• Analyze
• Simplify
• Optimize
• Automation

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

17
Doubts about CIM

• The main weakness of CIM building are
  administrative
• absence of long time information strategy
• Not filfilled expectations Underestimating of
  human factor
• Incompatibility of software and hardware
• Dilemma in usage of information systems

18
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

19
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

20
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.

21
Computer science

• Computer science is science about systematic
  information processing, especially about
  automated information processing by computers
• Computer Science - Informatics
