process type used for work that is nonroutine, with a unique set of objectives to be accomplished in a limited time frame. p. 243

Question 4

product or service profiling

Answer 4

linking key product or service requirements to process capabilities p. 245

Question 5

technological innovation

Answer 5

the discovery and development of new or improved products, services, or processes for producing or providing them p.244

Question 6

Answer 7

most advanced and developed equipment and methods p. 245

Question 8

process technology

Answer 8

includes methods, procedures, and equipment used to produce goods and provide services p.245

Question 9

Information technology (IT)

Answer 9

the science and use of computers and other electronic equipment to store, process, and send information p.245

Question 10

automation

Answer 10

machinery that has sensing and control devices that enable it to operate automatically p.245 (fixed, programmable, flexible)

Question 11

Fixed automation

Answer 11

uses high-cost, specialized equipment for a fixed sequence of operations. Adv. low cost and high volume. dis. min. variety and high cost to change

Question 12

programmable automation

Answer 12

use of high-cost, general purpose equipment controlled by a computer program that provides both the sequence of operations and specific details about each operation. ex. N/C machines, CAM. p.247

Question 13

Computer-aided manufacturing (CAM)

Answer 13

the use of computers in process control p. 247

Question 14

Numerically controlled (N/C) machines

Answer 14

machines that perform operations by following mathematical processing instructions p.247

• computerized numerical control (CNC) -machines with own computer
• direct numerical control (DNC) - one computer controls many machines

Question 15

flexible automation

Answer 15

uses equipment that is more customized than programmable automation. Lower changeover time permits almost continuous operation of equipment and product variety without the need to produce in batches. (FMS and CIM) p.248

Question 16

flexible manufacturing system (FMS)

Answer 16

group of machines designed to handle intermittent processing requirements and produce a variety of similar products p.248

Question 17

computer-integrated manufacturing (CIM)

Answer 17

a system for linking a broad range of manufacturing activities, such as purchasing,order processing and production planning, through an integrating computer system p. 248

Question 18

layout

Answer 18

the configuration of departments, work centers, and equipment with particular emphasis on movement of work (customers or materials) through the system p.250
3 types: product, process, fixed position

Question 19

product layout

Answer 19

uses standardized processing operations to achieve smooth, rapid, high-volume flow (production, assembly lines) p.250

Question 20

production line

Answer 20

standardized layout arranged according to a fixed sequence of production tasks p. 251
also U-shaped, service ex. cafe line, car wash

Question 21

assembly line

Answer 21

standardized layout arranged according to a fixed sequence of assembly tasks p.251

Question 22

process (functional) layout

Answer 22

can handle varied processing requirements p.253

Question 23

intermittent processing

Answer 23

nonrepetitive processing p.253

Question 24

fixed position layouts

Answer 24

the product or project remains stationary, and workers, materials, and equipment are moved as needed i.e. construction p.254

Question 25

cellular production

Answer 25

workstations are grouped into a cell that can process items that have similar processing requirements (part families) often uses SMED, right-sized equipment p.256

Question 26

group technology

Answer 26

grouping into part families of items with similar design or manufacturing characteristics. p.257 accomplished by visual inspection, examination of design and production data, production flow analysis

Question 27

other types of layouts

Answer 27

service, warehouse and storage, retail,office, restaurant, hospital p.260

Question 28

Line balancing

Answer 28

assigning tasks to workstations in such a way that the workstations have approximately equal time requirements. p.262

Answer 29

the maximum time allowed at each workstation to complete its set of tasks on a unit p.263

Question 30

precedence diagram

Answer 30

shows elemental tasks and their precedence requirements p.264

Question 31

balance delay

Answer 31

percentage of idle time of a line p.265
