Mng sys and design control

Question 1

Facility Layout and Work Flow

Answer 1

Arrangement within a factory of

Machines

Departments

Workstations

Storage areas

Aisles and common areas

Question 2

3 basic type of layout

Answer 2

process

product

fixed position

Question 3

3 hybrid layouts

Answer 3

Cellular

Flexible manufacturing systems

Mixed-model assembly lines

Question 4

Process layout

Answer 4

Similar activities grouped together in work areas (E.g. Plating, Milling, Assemnling etc…)

Suitable for low volume/batch production

Flexible

Not very efficient

Question 5

Product layout

Answer 5

Arrange activities in sequence of operation

Efficient

Not flexible

Specialized machines

Suitable for mass production

Question 6

Fixed position layout

Answer 6

Large projects too big to move

Equipment and parts moved in and out of work area

Highly skilled workers make it costly

Question 7

Hybrid layouts

Answer 7

try to mix flexibility of process layout with efficiency of product layout

Question 8

Cellular layouts

Answer 8

Machines grouped into cells

cells process part with similar features

Work cell resembles a small assembly line

Layout between cells treated as a process layout

Question 9

Flexible manufacturing systems

Answer 9

non-cost effective

Complex software

there is a small amount of FMS worldwide

Automates the entire manufacture of a product

Question 10

Flexible manufacturing cell

Answer 10

smaller version of FMS

One manufacturing process is automated

Question 11

Progressive FMS

Answer 11

All parts follow same progression through the work stations

Best where group technology can be applied

Question 12

Closed loop FMS

Answer 12

Larger variety of parts

Parts can follow different paths

Parts can skip stations

Question 13

Ladder FMS layout

Answer 13

Parts moved to and from any machine in any sequence

more flexible than progressive and closed loop systems

Question 14

Mixed model assembly lines

Answer 14

More than one product is processed by the line

Workers trained t work on more than one station

Layout of line changed

Long and short operations arranged to cancel each other

Question 15

Capacity Management

Answer 15

demand for product can fluctuate over time

If capacity is greater than demand there is a loss in business

Excess capacity means storage costs, labor costs etc…

Capacity planning is needed: match capacity to present anticipated demand

Question 16

Capacity Planning

Answer 16

Capacity Lead strategy

Capacity Lag strategy

Average capacity strategy

Question 17

Capacity Lead strategy

Answer 17

Capacity expanded in anticipation of demand

expect to gain customers from competition

Question 18

Capacity Lag strategy

Answer 18

Capacity increased after increase in demand

Common in markets where there is weak competition

Question 19

Average capacity strategy

Answer 19

capacity expanded to match with average expected demand
