1.INTEGRATED MAUFACTURING SYSTEM
2.INTEGRATED MANUFACTURING SYSTEM
Integrated manufacturing uses computers to connect physically separated processes.
When integrated, the processes can share information and initiate actions.
This allows decisions to be made faster and with fewer errors.
A complex example is an entire manufacturing plant with hundreds of workstations connected to a central database.

3.WHY INTEGRATE ?
A large organization where interdepartmental communication is a problem.
The need to monitor processes.

5. COMPUTER AIDED DESIGN
Computer-aided design (CAD) is the use of computer systems to assist in the creation, modification, analysis, or optimization of a design.
Computer-aided drafting describes the process of creating a technical drawing with the use of computer software.
CAD software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing.
CAD output is often in the form of electronic files for print or machining operations.

6.COMPUTER AIDED MANUFACTURING
Computer-aided manufacturing (CAM) is the use of computer software to control machine tools and related machinery in the manufacturing of work pieces.
CAM may also refer to the use of a computer to assist in all operations of a manufacturing plant, including planning, management, transportation and storage.
Its primary purpose is to create a faster production process and components and tooling with more precise dimensions and material consistency, which in some cases, uses only the required amount of raw material (thus minimizing waste), while simultaneously reducing energy.

7.COMPUTER-AIDED PROCESS PLANNING (CAPP)
Computer-aided process planning (CAPP) is the use of computer technology to aid in the process planning of a part or product, in manufacturing.
CAPP is the link between CAD and CAM in that it provides for the planning of the process to be used in producing a designed part.
Process planning is concerned with determining the sequence of individual manufacturing operations needed to produce a given part or product.
Process planning in manufacturing also refers to the planning of use of blanks, spare parts, packaging material, user instructions (manuals) etc.

10.CASE STUDY :A MODEL FOR AN INTEGRATED MANUFACTURING SYSTEM IMPLEMENTATION IN CHINA
ABOUT COMPANIES IN CHINA:-
In mainland china in 1985-95 the average living standard and the educational standards are still low; the technical standard in the southern regions is not as high as in the north; and the huge labour force is basically unskilled. Before ‘the open-door policy’ in China ;
all the enterprises, organisations and factories were state-owned. At that time, regardless of how hard anyone worked or, to the other extreme how lazy anyone was, the reward was exactly the same.
In other words, workers lacked incentive. Seniority was the key
consideration for promotion. Essentially there was no motivation among the working force at large.
Consequently, productivity remained at a low level.

11.PROPOSAL OF STEP MODEL
In order to achieve such integrated manufacturing system, STEP MODEL is proposed which is shown in Fig. 1.
This conceptual model can be divided into four majors steps.
The integration process starts with by the implementation of TQM.
Real-Time Monitoring System is proposed to be the hardware ingredient for the integration with TQM ideology.
MRPII. is integrated with RTMS in order to enhance the internal communication of the shop floor and production planning and control.
Appropriate ‘High-tech’ manufacturing technology can be used to assist the integration process.
Finally, the vision of an integrated manufacturing system can be achieved.

12.STRATEGY FORMULATION AND IMPLEMENTATION
Essentially, it follows four major phases:
i. establish the present position,
ii. Analyse strategic requirements,
iii. develop strategic improvements, and
iv. formulate implementation strategy.
This process is conducted by a team consisting of the general manager, manufacturing director, plant managers, engineering, quality, marketing, human resources and information system. In addition, an external consultant is employed to act as the facilitator who provide the experience and guidance. Much of the planning is done in small group meetings which allows time for interchange of ideas and discussion.

13.The integrated manufacturing strategies become apparent
when going through the steps, which are addressed as follows:
Manufacturing strategies needed to respond to business strategies
Comparison of present levels of manufacturing performance with future requirements
Strategies that remedy present weaknesses and exploit strengths.
Strategies to cope with the political, economical and social environment in China
Competitive advantages to sustain business growth

Good monitoring of whole system.
Good customer service.
Quality improvement.
Production cost reduction.
16.Accordingly, the adoption of an integrated manufacturing system is preferable to the manufacturing of ‘High-tech’ product or ‘High-tech’ manufacturing technology in Hong Kong. By adopting the integrated manufacturing system, and through continuing improvement and integration, the company has avoided the costs and risks of fishing in the diminishing pool of invention potential. The company has given herself time to learn and adopt to change business environment and technology. As a result, the productivity, and hence the profitability of the company is increased.
