Resource Scheduling and Optimisation Flashcards
The critical path on a project network is:
A the shorts path in duration through the network.
B the path with the most float.
C the path with the most activities on it.
D the longest path in duration through the network.
D the longest path in duration through the network.
The critical path in the network diagram shown below is:
A 5 - B 5 - D 5 - F 5
\ /
C 4 - E 4
A ACEF
B ABDF
C ACDF
D ABEF
B ABDF
In the above network diagram, which of the activities have total float:
A C and E
B B and D
C A only
D E only
A C and E
The diagram below shows the relationship between task A and task B.
Task A ______Task B
According to this diagram the dependency shown is an example of:
A Finish to start
B Finish to finish
C Start to finish
D Start to start
B Finish to finish
Which of the following best describes the concept of total float?
A The value of the earliest finish of an activity subtracted from the latest finish of the previous activity.
B The value of the latest finish of an activity subtracted from the earliest start of the same activity.
C The amount an activity can slip without affecting the overall duration of the project.
D The amount an activity can slip without affecting the start of the next activity.
C The amount an activity can slip without affecting the overall duration of the project.
In a situation where time becomes more important than cost, the project manager should first attempt to:
A remove resources from critical tasks.
B perform time limited scheduling (smoothing).
C redefine the critical path.
D perform resource limited smoothing (levelling).
B perform time limited scheduling (smoothing).
To maintain the scheduled duration when resources are limited, resource levelling should first attempt to:
A not exceed pre-determined end date.
B schedule activities within the limits of their floats.
C extend the activity duration.
D minimise the use of overtime.
B schedule activities within the limits of their floats.
The Gantt chart below shows the scheduling of seven tasks (A-G) and their daily allocation of resources over a 9 day period. Activities B and F have total float to the extent as indicated by the dotted line.
A 2 2 2
B 3 3
C 1 1
D 2 2 2
E 2 2
F 3——-
G 2

Which of the possible actions would be considered the best application of resource smoothing?
A Double the amount of resources applied to activity B, reducing its duration to 1 day.
B Delay activity F to start on day 5 and finish on day 7, reducing to 1 resource per day.
C Extend the overall schedule duration by 3 days and start the project on day 3.
D Double the amount of resources applied to activity E reducing its duration to day 1.
B Delay activity F to start on day 5 and finish on day 7, reducing to 1 resource per day.

If the total number of resources available is limited to 6 per day, what would be the most efficient way to deal with this constraint?
A increase the project budget to acquire additional resources.
B Extend the overall project duration by 3 days.
C Move activity B and F to the extent of their float.
D Move activity F only to start on day 5.
D Move activity F only to start on day 5.

If resource levelling was being considered to be applied to the schedule, which activities should be initially considered for this technique?
A All activities would be considered.
B Activities B and F would be initially considered.
C Activities A, C, D, E and G would be initially considered.
D There is not enough information provided to make such a decision.
B Activities B and F would be initially considered.
Procurement could be described as:
A an outline of the deliverables required by the project.
B a process by which the resources required by the project are acquired.
C an outline of the resources required for the project.
D a definition of who should be the best supplier of goods for the project.
B a process by which the resources required by the project are acquired.
Preparation of contracts, selection and acquisition of suppliers and management of the contracts would be items recorded in the:
A Responsibility matrix.
B Work breakdown structure.
C Business case.
D Procurement strategy.
D Procurement strategy.
One key principle a project manager should follow when carrying out procurement is to:
A ensure the same suppliers are used in each project to maintain consistency.
B always use the supplier who will offer the lowest price.
C always bring in specialist help for support.
D always use an objective process when selecting suppliers.
D always use an objective process when selecting suppliers.
Which of the following would best describe a contract?
A An agreement made between two or more parties that creates legally binding obligations between them.
B An invitation for a supplier to tend at the lowest price.
C A stage or work package carried out by a chosen supplier.
D An accepted completed work package.
A An agreement made between two or more parties that creates legally binding obligations between them.
When acquiring goods or services for the project what might be the most important question for the project manager to raise with the sponsor with regard to contract?
A How many suppliers from the market might be willing to submit a tender response.
B If the previous supplier to the project can also be used for the project currently being planned.
C How much risk to retain in the project and how much to share with suppliers in the supply chain?
D How much previous experience does the organisation have with the suppliers that are currently being considered?
C How much risk to retain in the project and how much to share with suppliers in the supply chain?
