GANTT CHARTS

Gantt Chart - A bar graph that shows what projects are being worked on and how much has been completed. PERT and GANTT are both used to control manufacturing processes

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. Toyota: The inventor of 'Just-in-Time Processing' : https://youtu.be/cAUXHJBB5CM

MRP and ERP

Materials Requirement Planning (MRP) -- A computer-based operations management system that uses sales forecasts to make sure parts and materials are available when needed. Enterprise Resource Planning (ERP) -- A newer version of MRP, combines computerized functions into a single integrated software program using a single database.

PROCESS and ASSEMBLY in PRODUCTION

Process Manufacturing -- The part of production that physically or chemically changes materials. Assembly Process -- The part of the production process that puts together components.

PRODUCTION and MANAGEMENT

Production -- The creation of goods using land, labor, capital, entrepreneurship and knowledge (the factors of production). Production Management -- All the activities managers do to help firms create goods.

PERT

Program Evaluation and Review Technique (PERT) -- A method for analyzing the tasks involved in completing a given project and estimating the time needed. a statistical tool used in project management, which was designed to analyze and represent the tasks involved in completing a given project.

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.

The PRODUCTION PROCESS

a single firm can produce output at a lower cost than can a larger number of firms (slide 9)

Facility Location --

he process of selecting a geographic location for a company's operations.

Operations Management -

A specialized area in management that converts or transforms resources into goods and services. Operations management includes: Inventory management Quality control Production scheduling Follow-up services

FACILITY LAYOUT OPTIONS

Assembly Line Layout - Workers do only a few tasks at a time. (often called product layout) Modular Layout - Teams of workers produce more complex units of the final product. Fixed-Position Layout - Allows workers to congregate around the product. Process Layout - Similar equipment and functions are grouped together.

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.

DEVELOPMENTS MAKING U.S. COMPANIES MORE COMPETITIVE

Computer-aided design and manufacturing Flexible manufacturing Lean manufacturing Mass customization

Flexible Manufacturing -

Designing machines to do multiple tasks so they can produce a variety of products. Allen-Bradley uses flexible manufacturing to build motor starters. 26 machines and robots build, test and package parts.

OPERATIONS MANAGEMENT PLANNING

Operations management planning helps solve problems like: Facility location Facility layout Materials requirement planning Purchasing Inventory control Quality control

QUALITY CONTROL

Quality -- Consistently producing what the customer wants while reducing errors before and after delivery. Six Sigma Quality -- A quality measure that allows only 3.4 product defects per million opportunities

Mass Customization -

Tailoring products to meet the needs of a large number of individual customers. More manufacturers are learning to customize. Mass customization exists in the service sector too.

The PRODUCTION PROCESS

The production process takes inputs such as land, labor, capital, entrepreneurship, and knowledge to produce outputs in the form of goods, services, and ideas. This is accomplished by using the production control activities of planning, routing, scheduling, dispatching, and follow-up.
