CIM Method of Manufacturing and the name of a

computer-automated system .

 It is the manufacturing approach of using computers to control the entire production process.

The complete automation of a manufacturing plant, with all processes functioning under computer control and digital information tying them together.

CIM ObjectivesSimplify production processes and product designs.

Automates production processes with computers, machines, and robots

Integrate all production and support processes using computer networks and other information technologies

The primary objectives of CIM are to improve service to customers, increase flexibility, boost productivity and sustain profitable operations.

Subsystems in CIM operationComputer-aided design( CAD) Use of computer technology for the process of

design and design-documentation.  FIG: CAD model of a computer mouse

Computer-aided manufacturing ( CAM) Use of computer software to control machine

tools and related machinery in the manufacturing of work pieces.

Key IssuesEquipment incompatibility and difficulty of

integration of protocols.

Integrating different brand equipment controllers with robots, conveyors and supervisory controllers is a time-consuming task with a lot of pitfalls.

Large investment and time required for software, hardware, communications, and integration cannot be financially justified easily.

Vertical Integration

 Vertical integration is typified by one firm engaged in different parts of production (e.g. growing raw materials, manufacturing, transporting, marketing, and/or retailing).

Nineteenth century steel tycoon Andrew Carnegie introduced the concept and use of vertical integration. This led other businesspeople to use the system to promote better financial growth and efficiency in their businesses

AdvantagesLower transaction cost:  due to inter transactions

between subsidiary companies.High certainty of Quality:  since the subsidiary

companies have a common quality control system .Ability to monopolies the market:

This type of situation will start from the production of raw materials all the way to production, then distribution. This will assist the company to control all the lines of business as such controlling Entrants to the same business - hence control against competition.

DisadvantageHigher Monitory and Organizational Costs. 

This can be brought about by a company having a big organizational structure which leads to higher cost for managing such a structure.

3 types of Vertical integrationA company exhibits backward vertical

integration when it controls subsidiaries that produce some of the inputs used in the production of its products.

Example- Automobile-Tire , glass & metal company

A company tends toward forward vertical integration when it controls distribution centers and retailers where its products are sold.

Ex- Reliance

Balanced vertical integration means a firm controls all of these components, from raw materials to final delivery.

Ex- Tata

ExamplesCarnegie Steel company.The company controlled

not only the mills where the steel was made, but also the mines where the iron ore was extracted, the coal mines that supplied the coal, the ships that transported the iron ore and the railroads that transported the coal to the factory,
