Answer 4

Batching

Question 5

What is a process?

Answer 5

A network of activities performed by resources that transform inputs into outputs

Question 6

What are the 3 elements in a process flow diagram

Answer 6

1. Activity
2. Storage Area or Buffer
3. Decision point

Question 7

What is a Process Flow Diagram

Answer 7

A symbolic representation of a process

Question 8

What moves along the arrows of a process flow diagram

Answer 8

Inputs and outputs only
Activities do not

Question 9

What is the flow time

Answer 9

Total time that a flow unit spends in an activity/process

unit of time

Question 10

What is the inventory

Answer 10

Number of flow units in an activity/process at any point in time

#

Question 11

What is throughput

Answer 11

Number of flow units through an activity/process per unit of time

/ unit of time

Question 12

What is Little’s Law

Answer 12

Inventory = Throughput * Flow Time

L = lambda * W

Question 13

What is Cycle Time

Answer 13

Average time between two consecutive flow units exiting an activity/process, which is working continuously

unit of time

Question 14

What is Capacity

Answer 14

Throughput of an activity/process if it is working continuously

/ unit of time

Question 15

What is the cycle time equation?

Answer 15

Cycle time =
1 / Capacity

Question 16

What is the measure of process performance in this case:
How long does it take to produce a product

Answer 16

Flow time

Question 17

What is the measure of process performance in this case:

How many units can the process produce during a given time interval

Answer 17

Capacity
and
Cycle time

Question 18

What is the measure of process performance in this case:

What is the level of work-in-process inventory?

Answer 18

Inventory

Question 19

What is the process capacity?

Answer 19

Capacity of the process is the capacity of the bottleneck

Question 20

What is a resource?

Answer 20

Any person, place, or thing which is required in order for an activity to run

Question 21

What is the bottleneck resource?

Answer 21

The resource with the lowest capacity or highest cycle time

Question 22

What is utilization (definition)?

Answer 22

The utilization of a resource is the percentage of the capacity that is utilized

Question 23

What is utilization (equation)

Answer 23

Utilization = Throughput / Capacity

Question 24

What is the recipe for a bottleneck analysis

Answer 24

1. List activities, times, and resources
2. Group the activities performed by each resources
3. Capacity analysis for each resource
4. Capacity of process = capacity of the resource with the smallest capacity (bottleneck)

Question 25

What are 4 ways to improve a process

Answer 25

1. Increase the bottleneck resource
2. Pool the bottleneck resource with non-bottleneck resources
3. Change the batch size
4. Eliminate some non-bottleneck resources
