“Globalization has collapsed time and distance and raised the notion
that someone anywhere on earth can do your job, more cheaply”
World is Flat, author Thomas L. Friedman (2006)
14
Globalization and
Manufacturing
•
•
In recent years the manufacturing
industry has been strongly impacted by
globalization, which has resulted in
increased global competition.
This manufacturing competition has
acted as a driving force for the
application of new, related technologies
in industry. In order to sustain their
competitiveness, companies need to be
able to adapt quickly to rapidly changing
conditions of both the market and their
competitors at reduced cost and at least
equivalent or better quality.
15
Manufacturing Systems

Manufacturing systems involve activities related to the production
of goods using manufacturing resources and knowledge,
according to the external demands and subject to the
environmental context, e.g. social and economic aspects.
16
Computer Integrated
Manufacturing

The Computer Integrated Manufacturing (CIM) paradigm, popular in the
eighties, consists of the integration of the enterprise activities, related with
the production, through the use of information technologies, such as
databases and networks, which allows the exchange and sharing of data.
•
The CIM paradigm also aims the
integration of several computer-aided
technologies that support the
production systems, such as Computer
Aided Design (CAD), Computer Aided
Engineering (CAE), Computer Aided
Manufacturing (CAM) and Computer
Aided Process Planning CAPP).
17
CIM - Definitions
Improving shop-floor communications is the primary goal.

Others extend the degree of integration to encompass communication
between engineering and manufacturing functions.
In general:

The ultimate benefit of CIM is the improvement of communication and
control of information flow to all aspects of an enterprise. Integrating
information and organizations will decrease the logistical size of a
company, making it appear to be small again-at least from the
management, administration, and information-sharing viewpoints.

The goal of CIM is to provide the computer applications and
communications needed to bring about the integration (with matching
organization changes) that will allow a company to take advantage of
these new capabilities.

Objectives of an Enterprise





Manage manufacturing finance and
accounting
Develop enterprise directives and financial
plans
Develop and design products and
manufacturing processes
Conduct manufacturing operations
Manage external demands
CIM as solution to enterprises
CIM as solution to enterprises


In Marketing, CIM helps manage customer
satisfaction by allowing electronic order entry
from customers... through faster response to
customer inquiries and changes...and with more
accurate sales projections.
In Engineering and Research, CIM benefits include
quicker design, development, prototyping and
testing... faster access to current and historical
product information...and a method for paperless
release of products, processes and engineering
changes to manufacturing.
CIM as solution to enterprises


In Production Planning CIM offers more accurate,
realistic production scheduling...while it requires less
expediting, canceling and rescheduling of production
and purchase orders.
Within Plant Operations, CIM provides the means to
assist the manufacturing operations in controlling
processes, optimizing inventory, improving yields,
managing changes to products and processes,
reducing scrap and rework. CIM also helps utilize
people and equipment more effectively.. .and
reduces crisis production demands as well as lead
times and product costs.
CIM as solution to enterprises


In Physical Distribution, where external demands are
satisfied with products shipped to the customer, CIM
helps plan requirements...manage the flow of products
.improve efficiency of shipping, vehicle and service
scheduling...allocate supply to distribution centers...and
expedite processing of returned goods.
For Business Management activities such as managing
manufacturing finance and accounting, and developing
enterprise directives and financial plans. CIM offers better
product’ cost tracking...more accuracy in financial
projections...and improved cash flow..
CIM as solution to enterprises

For the enterprise as a whole, these advantages add
up to faster release of new products.. .shorter
delivery times.. .optimized finished goods
inventory...shorter production planning and
development cycles.. .reduced production lead
times... improved product quality, reliability and
serviceability...increased responsiveness and greater
competitiveness. In effect, CIM replaces an
enterprise’s short-term tactical improvements with a
long-term strategic solution
CIM Major Benefits



Improvement labor productivity
Improvement Equipment productivity
Lower the cost of the product
CIM Major Problem


the difficulties in understanding the technology
and organizational impediments.
lack of direction and cost justification indicating
that support for CIM programs by top level
management is necessary to improve the success
of CIM programs.
