Quiz 1 Sessions 1,2,3

Question 1

production

Answer 1

creation of goods and services

Question 2

operations management

Answer 2

the set of activities that creates goods and services by transforming inputs into outputs

Question 3

objective of operations management

Answer 3

• provide the goods and services needed to meet requirements effectively
• create and maintain transformation processes that are efficient and ethical
• continuously improve the outputs and the system’s efficiency

(ie, provide goods and services effectively, create/maintain processes that are efficient, improve the outputs/efficiency)

Question 4

productivity

Answer 4

ratio of outputs divided by one or more inputs

productivity=outputs produced/inputs used

Question 5

single factor productivity

Answer 5

indicates the ratio of one resource to the goods and services produced

eg, output/labour

Question 6

multifactor productivity

Answer 6

output / (labour + material + energy + capital + miscellaneous)

Question 7

task time

Answer 7

time from start of work on a unit to the completion of that unit at a given task

Question 8

cycle time

Answer 8

time from completion of one unit to the completion of the next unit

(cycle time = bottleneck time)

Question 9

throughput time

Answer 9

time from start of work on a unit at task 1 to the completion of work on that unit at task 5; includes wait time

(sum of all processing times of all tasks + any wait time)

Question 10

WIP (work in process)

Answer 10

inventory that is no longer raw material but has yet to become a finished product

Question 11

why/when does WIP occur

Answer 11

due to line imbalances (eg, bottleneck) so it builds up before the bottleneck task

Question 12

bottleneck

Answer 12

limits production and contsrains output rate; sets ceiling on rate at which units move through process so it then determines the cycle time

the most highly used resource

Question 13

output rate

Answer 13

number of units that can be produced per unit of time

can be calculated with cycle time (ie, process capacity)

output rate = 1 / cycle time

Question 14

capacity

Answer 14

another term used for output rate for a process stage or the overall process (ie, it is a measure of output per unit of time)

Question 15

process capaity

Answer 15

a measure of the output rate for the process and is determined by the bottleneck

depends on the level of resources deployed at process stages and the effectiveness of the resources utilized

Question 16

tasks and resources

Answer 16

tasks are performed by resources (eg, labour and equipment); the bottleneck will be the most highly utilized resources

Question 17

relative measure

Answer 17

compares to similar operations within the industry or the same operation over time

Question 18

how to improve process capacity

Answer 18

-decrease time to perform bottleneck
-increase resources at bottleneck
-re-assign work for balance (more resources or less work at bottleneck)
-extend the operating period
-reduce waste at bottleneck

Question 19

parallel processes

Answer 19

eg, adding a second worker to the bottleneck task
