*new products or services.
*morale problems.
A number of factors affect layout planning.
question
Which of the following is not true about process layouts when they are compared to product layouts?
answer
lower unit costs
Process layouts are not inherently more efficient that product layouts.
question
Product profiling links key product or service requirements to:
answer
process capabilities.
Product profiling allows firms to match what they should (or must) do with respect to product or service requirements.
question
Layout design has many objectives, one of which is:
answer
use workers and space efficiently.

question
A production line is to be designed for a job with three tasks. The task times are .4 minutes, 1.2 minutes, and .5 minutes. The maximum cycle time in minutes is:
answer
2.1
This assumes only one workstation.
question
A production line is to be designed for a job with three tasks. The task times are .3 minutes, 1.4 minutes, and .7 minutes. The minimum cycle time in minutes is:
answer
1.4
The longest task time equals the minimum cycle time.
question
Daily capacity of a product layout is determined by:
answer
operating time divided by cycle time.
This represents how many units are possible per day.
question
The maximum allowable cycle time is computed as:
answer
daily operating time divided by the desired output.
If this is smaller than the minimum cycle time, extra workstations will be necessary.
question

answer
*Product
*Process
Heuristics help in formulating reasonably good product and process layouts.
question
Which of these items would be most likely to be made with a fixed-position layout?

Eliminate boundaries for the service and decide on the level of interaction needed.
Defining boundaries is a critical part of service blueprinting.
question
Service design generally differs from product design in which of the following ways?
answer
There is less latitude in detecting and correcting errors prior to delivery.
Often service design flaws are not discovered until some customers have been served.
question
One of these is not a characteristic of a well-designed service system:
answer
distributed computer networks
Well-designed service systems tend to be user friendly, robust, cost-effective, and easy to sustain.

question
A manufacturing firm is considering two locations for a plant to produce a new product. The two locations have fixed and variable costs as follows:
Atlanta: FC Annual $80,000, VC per unit $20
Phoenix: FC Annual $140,000, VC per unit $16

answer
$300,000
question
The method for evaluating location alternatives that minimizes shipping costs between multiple sending and receiving locations is:
answer
transportation model analysis.
question
A location analysis has been narrowed down to two locations, Akron and Boston. The main factors in the decision will be the supply of raw materials, which has a weight of .50, transportation cost, which has a weight of .40, and labor cost, which has a weight of .10. The scores for raw materials, transportation, and labor are for Akron 60, 80, and 70, respectively; for Boston 70, 50, and 90, respectively. Given this information and a minimum acceptable composite score of 75, we can say that the manager should:
answer
reject both locations.
