IntroductionIntroduction

Computer integrated manufacturing has been described as everything from an intangible philosophy to a specific CNC program. Further complicating the process of arriving at a consensus for the conceptualization of the term, is the issue of where in the organization CIM resides. Is it a management tool, a planning tool? Is it a production floor activity? Or does CIM somehow fit into an enterprise resource planning (ERP) model?

IntroductionIntroduction

Some see CIM as an integration tool, a tool which uses information and automation hardware and software for production control and management. This school of thought views CIM as a total integrative tool for the organization, one which has the ability to increase productivity, quality and competitive advantage.

IntroductionIntroduction

Another organizational perspective of CIM is that of a "management technology that makes feasible the fully-automated factory-of-the-future." With this perspective, CIM allows the organization to fully integrate and control all design and manufacturing functions.

SynonymsSynonyms CIE - computer integrated enterprise

CIME - computer integrated manufacturing enterprise

CIM means many different things to many different people.

IntroductionIntroductionAn attempt to define CIM is analogous to a group of blind people trying to describe an elephant by touching it; each has a different description depending upon the body part touched. Thus, several definitions of CIM have been attempted. The one put forward by Shrenker for the Computer and Automated Systems Association of the Society of Manufacturing Engineers (CASA/SME) is perhaps the most appropriate.

IntroductionIntroduction

According to him “CIM is the integration of the total manufacturing enterprise through the use of integrated systems and data communications coupled with new managerial philosophies that improve organizational and personnel efficiency”

CIM WheelCIM Wheel1985 -The Computer and Automated

Systems Association of the Society of Manufacturing Engineers (CASA/SME) published its vision of enterprise-wide teaming--the CIM Enterprise Wheel.

1992 -New Manufacturing Enterprise Wheel. This updated vision preserves the understanding gained from the previous CIM Enterprise Wheel. The old Wheel looked primarily at automation and integration inside the enterprise. The new Wheel looks outside as well. It adds understanding in these six areas:

CIM WheelCIM Wheel The central role of a customer-oriented mission and

vision to strive for continuous improvement. The importance of teams and human networking in

the new manufacturing environment. The continuing importance of computer tools, now

increasingly distributed and networked. This includes tools to support networking and concurrent engineering.

A focus on key processes and best practices throughout the enterprise, from marketing through design, manufacturing, and customer support.

Recognition of the move away from bureaucratic structures, to leaner and more agile organizations.

The need to integrate an understanding of the external environment, including customers, competitors, suppliers, and the global manufacturing infrastructure.

CIM WheelCIM Wheel The new Manufacturing Enterprise Wheel

describes six fundamental elements for competitive manufacturing:

The central role of the customer and evolving customer needs.

The role of people and teamwork in the organization.

The revolutionary impact of shared knowledge and systems to support people and processes.

Key processes from product definition through manufacturing and customer support.

Enterprise resources (inputs) and responsibilities (outputs).
