• Form Utility -- The value producers add to materials in the creation of finished goods and services.

FORM UTILITY LG3

Production Processes

9-12

1. To build and deliver products in response to the demands of the customer at the scheduled delivery time.

2. To provide an acceptable quality level.

3. To provide everything at the lowest possible cost.

Production Processes

9-13

• Process Manufacturing -- The part of production that physically or chemically changes materials.

• Assembly Process -- The part of the production process that puts together components.

PROCESS and ASSEMBLY in PRODUCTIONLG3

Production Processes

9-14

• Production processes are either continuous or intermittent.

• Continuous Process -- Long production runs turn out finished goods over time.

• Intermittent Process -- Production runs are short and the producer adjusts machines frequently to make different products.

The Need to Improve Production Techniques and Cut Costs

DEVELOPMENTS MAKING U.S. COMPANIES MORE COMPETITIVE

1. Computer-aided design and manufacturing

2. Flexible manufacturing

3. Lean manufacturing

4. Mass customization

Computer-Aided Design and Manufacturing

COMPUTER-AIDED DESIGN and MANUFACTURING

• Computer-Aided Design (CAD) -- The use of computers in the design of products.

• Computer-Aided Manufacturing (CAM) -- The use of computers in the manufacturing of products.

LG3

9-17

Computer-Aided Design and Manufacturing

COMPUTER-INTEGRATED MANUFACTURING

• Computer-Integrated Manufacturing (CIM) -- The uniting of computer-aided design with computer-aided manufacturing.

• CIM is expensive but it cuts as much as 80% of the time needed to program machines to make parts.

LG3

9-18

Flexible Manufacturing TYPES OF MANUFACTURING

• Flexible Manufacturing -- Designing machines to do multiple tasks so they can produce a variety of products.

• Lean Manufacturing -- Using less of everything than in mass production.

• Compared to others, lean companies:- Take half the human effort.

- Have half the defects in finished products.

- Require one-third the engineering effort.

- Use half the floor space.

- Carry 90% less inventory.

Mass Customization MASS CUSTOMIZATION

• Mass Customization -- Tailoring products to meet the needs of a large number of individual customers.

LG3

• More manufacturers are learning to customize.

• Mass customization exists in the service sector too.

Operations Management Planning

• Operations management planning helps solve problems like:

- Facility location

- Facility layout

- Materials requirement planning

- Purchasing

- Inventory control

- Quality control

OPERATIONS MANAGEMENTLG4

9-21

Facility Location

• Facility Location -- The process of selecting a geographic location for a company ’s operations.

FACILITY LOCATION

• Rising numbers of Internet businesses means brick-and-mortar retailers must find great locations.

SETTING UP the FACILITYLG4

9-25

1. Assembly Line Layout – Workers do only a few tasks at a time.

2. Modular Layout – Teams of workers produce more complex units of the final product.

3. Fixed-Position Layout – Allows workers to congregate around the product.

4. Process Layout – Similar equipment and functions are grouped together.

FACILITY LAYOUT OPTIONSLG4

Just-in-Time Inventory Control

• Just-in-Time (JIT) Inventory Control -- The production process in which a minimum of inventory is kept and parts, supplies and other needs are delivered just in time to go on the assembly line.

• To work effectively, the process requires excellent coordination with suppliers.

INVENTORY CONTROLLG4
