4. The Realities of Modern
Manufacturing
 Globalization - Once underdeveloped countries (e.g.,
China, India, Mexico) are becoming major players in
manufacturing
 International outsourcing - Parts and products once made
in the United States by American companies are now
being made offshore (overseas) or near-shore (in Mexico
and Central America)
 Local outsourcing - Use of suppliers within the U.S. to
provide parts and services

5. More Realities of Modern
Manufacturing
 Contract manufacturing - Companies that specialize in
manufacturing entire products, not just parts, under
contract to other companies
 Trend toward the service sector in the U.S. economy
 Quality expectations - Customers, both consumer and
corporate, demand products of the highest quality
 Need for operational efficiency - U.S. manufacturers must
be efficient in their operations to overcome the labor cost
advantage of international competitors

6. Modern Manufacturing Approaches
and Technologies
 Automation - automated equipment instead of labor
(reduces labor cost, decreases production cycle times,
increases product quality and consistency)
 Material handling technologies - manufacturing usually
involves a sequence of activities; material handling
provides transportation, storage and tracking of
materials through the plant
 Manufacturing systems - integration and coordination
of multiple automated or manual workstations through
material handling technologies

7. Modern Manufacturing Approaches
and Technologies
 Flexible manufacturing - to compete in the low-
volume/high-mix product categories
 Quality programs - to achieve the high quality expected
by today's customers
 Computer Integrated Manufacturing (CIM) - to integrate
design, production, and logistics

8. Production System Defined
“A collection of people, equipment, and procedures
organized to accomplish the manufacturing operations of
a company”
Two categories:
 Facilities – the factory and equipment in the facility and
the way the facility is organized (plant layout)
 Manufacturing support systems – the set of procedures
used by a company to manage production and to solve
technical and logistics problems in ordering materials,
moving work through the factory, and ensuring that
products meet quality standards

11. Manufacturing Systems
Three categories in terms of the human participation in
the processes performed by the manufacturing system:
1. Manual work systems - a worker performing one or
more tasks without the aid of powered tools, but
sometimes using hand tools
2. Worker-machine systems - a worker operating
powered equipment
3. Automated systems - a process performed by a
machine without direct participation of a human

15. Automated System
 A semi-automated machine performs a portion of the work
cycle under some form of program control, and a human
worker tends to the machine for the remainder of the
cycle, by unloading and loading it, or performing some
other task each cycle.
 A fully automated machine has the capacity to operate for
extended periods of time with no human attention.

17. Manufacturing Support Systems
Involves a cycle of information-processing activities that consists of
four functions:
• Business functions – principal means of communicating with
customer
The production order will be in one of the following forms:
1. an order to manufacture an item to the customer’s
specifications
2. a customer order to buy manufacturer’s product
3. an internal company order based on a forecast of future
demand

18. Manufacturing Support Systems
• Product design - research and development, design engineering,
prototype shop
• Manufacturing planning – the information and documentation that
constitute the product design flows into the manufacturing
planning function
• Process planning: consists of determining the sequence of
individual processing and assembly operations needed to
produce the part
• Master Production Schedule (MPS) is a listing of the products
to be made, the dates on which they are to be delivered, and
the quantities of each
• Materials Requirement Planning (MRP): planning of individual
components and subassemblies that make up each product
• Capacity planning is concerned with manpower and machine
resources of the firm

19. Manufacturing Support Systems
• Manufacturing control – concerned with managing and controlling
the physical operations in the factory to implement the
manufacturing plans
• Shop floor control deals with the problem of controlling the
progress of the product as it is being processed, assembled,
moved, and inspected in the factory
• Inventory control attempts to strike a proper balance between
the risk of too little inventory (with possible stock-out of
materials) and the carrying cost of too much inventory, i.e.
what to order and when to order
• Quality control ensures that the quality of product and its
components meet the standards specified by the product
designer

21. Automation in Production Systems
Two categories of automation in the production system:
1. Automation of manufacturing systems in the
factory
2. Computerization of the manufacturing support
systems
 The two categories overlap because manufacturing
support systems are connected to the factory
manufacturing systems
 Computer-Integrated Manufacturing (CIM)

32. Computerized Manufacturing Support
Systems
Objectives of automating the manufacturing support systems:
 To reduce the amount of manual and clerical effort in product
design, manufacturing planning and control, and the business
functions
 Integrates computer-aided design (CAD) and computer-aided
manufacturing (CAM) in CAD/CAM
 CIM includes CAD/CAM and the business functions of the firm
The term CIM denoted the pervasive use of computer systems
to design the products, plan the production, control the
operations, and perform the various information-processing
functions needed in a manufacturing firm.

39. Ten Strategies for Automation and
Process Improvement
If automation seems a feasible solution to improving
productivity, quality or other measure of performance,
then the following ten strategies provide a road map to
search for these improvements.
1. Specialization of operations: The use of special-purpose
equipment designed to perform one operation with the
greatest possible efficiency.
2. Combined operations: Involves reducing the number of
distinct production machines or workstations through
which the part must be routed. Saves setup, material
handling effort, waiting time, lead time.
3. Simultaneous operations: Reduces total processing time.

and Computer-Integrated Manufacturing, Third Edition, by Mikell P. Groover. 38

40. Ten Strategies for Automation and
Process Improvement
4. Integration of operations: Linking several workstations
together into a single integrated mechanism, using
automated work handling devices to transfer parts
between stations.
5. Increased flexibility: Attempts to achieve maximum
utilization of equipment for job-shop and medium-
volume situations by using the same equipment for a
variety of parts or products (reduce setup and
programming time).
6. Improved material handling and storage: Reduces WIP
and shortens manufacturing lead time.
