Unlike most of the scheduling rules discussed in class, Johnson's rule actually finds an "optimal"
production schedule. correct answers True
Sequencing rules are often used in practice because ...
Developing and implementing an optimal (best) solution to a real-world scheduling problem can
be virtually impossible.
Monitoring rules load the sequence inefficiently.
Developing and implementing an optimal (best) solution to a real-world scheduling problem can
be virtually impossible.
Production managers are very busy and they just want to develop a schedule quickly so that they
can make sure products are getting made.
Gantt charts are impractical and not effective. correct answers Developing and implementing an
optimal (best) solution to a real-world scheduling problem can be virtually impossible

in class?

EDD
SPT
SLACK correct answers SPT
Production scheduling is a intermediate time frame planning activity. correct answers False
Calculate MAD using the following data. Round your answer off to 2 decimal places. Demand
for the past 4 periods was: 342, 355, 349, 348; Forecasts for the past 4 periods was: 347, 349,
348, 348 correct answers 3
Demand for the last four periods (beginning with the most recent demand) is 100, 90, 110, 120.

D.
All of the above
E.
None of the above correct answers Allows comparison of different forecasts that come from
different data and different models

E.
None of the above correct answers All of the above
The theory of constraints (also called synchronous manufacturing) suggests that the scheduling
of a bottleneck resource should be guided by the capacity of a non-bottleneck resource.
