OMIS 635 Test 2What is resource smoothing (or leveling)? - correct answer ✔✔Involves attempting to even out varying
demands
on resources by using slack (delaying noncritical activities) to manage resource utilization when
resources are adequate over the life of the project
What is resource-constrained scheduling? - correct answer ✔✔The duration of a project may be
increased by delaying the late start of some of its activities if resources are not adequate to meet peak
demands
What are technical or logic constraints? - correct answer ✔✔Constraints related to the networked
sequence in which project activities must occur
What are physical constraints? - correct answer ✔✔Activities that cannot occur in parallel or are affected
by contractual or environmental conditions
What are resource constraints? - correct answer ✔✔The absence, shortage, or unique interrelationship
and interaction characteristics of resources that require a particular sequencing of project activities
People, materials, equipment
What are the types of project constraints? - correct answer ✔✔-Technical or logic
-Physical
-Resource
How do you determine the classification of a problem? - correct answer ✔✔Using a priority matrix will
help determine if the project is time or resource constrained.
What is a time-constrained project? - correct answer ✔✔-Must be completed by an imposed date
,-Require use of leveling techniques that focus
on balancing or smoothing resource demands.
-Use positive slack (delaying noncritical activities) to manage resource utilization over the duration
of the project.
-Time is fixed, resources are flexible: additional resources are required to ensure project meets
schedule.
What is resource-constrained project? - correct answer ✔✔-Is one in which the level of resources
available cannot be exceeded.
-Resources are fixed, time is flexible: inadequate resources
will delay the project.
What are limiting assumptions? - correct answer ✔✔-Splitting activities is not allowed—once an activity
is start, it is carried to completion
-Level of resources used for an activity cannot be changed
What are risk assumptions? - correct answer ✔✔-Activities with the most slack pose the least risk.
-Reduction of flexibility does not increase risk.
-The nature of an activity (easy, complex) doesn't increase risk
What are the advantages of resource demand leveling techniques for time-constrained projects? -
correct answer ✔✔-Peak resource demands are reduced
-Resources over the life of the project are reduced
-Fluctuation in resource demand is minimized.
, What are the disadvantages of resource demand leveling techniques for time-constrained projects? -
correct answer ✔✔-Loss of flexibility that occurs from reducing slack
-Increases in the criticality of all activities
What are the order of heuristics
(rules-of-thumb)? - correct answer ✔✔1) Minimum slack
2) Smallest (least) duration
3) Lowest activity identification number
What is an EMR project? - correct answer ✔✔The development of a handheld electronic medical
reference guide to be used by emergency medical technicians and paramedics
What is the problem with EMR projects? - correct answer ✔✔There are only eight design engineers who
can be assigned to the project due to a shortage of design engineers and commitments to other projects.
What are the impacts of resource-constrained scheduling? - correct answer ✔✔-Reduces slack; reduces
flexibility
-Increases criticality of events
-Increases scheduling complexity
-May make the traditional critical path no longer meaningful
-Can break sequence of events
-May cause parallel activities to become sequential
-Activities with slack may become critical
What is splitting? - correct answer ✔✔-A scheduling technique for creating a better project schedule
and/or increase resource utilization
