Exam 10: Project Scheduling: Lagging, Crashing, and Activity Networks

What are the three principal methods for accelerating a project and under what circumstances might these methods yield little gain?

Use the information in the table to create a baseline Gantt chart for the project where activity lengths are given in days.

A basic Gantt chart:

-Use the Gantt chart and the activity list to determine which resource is used the most.

Most project management software employs AOA diagramming.

Gantt charts can display early start or late start logic.

A project has the activity duration and cost information indicated in the table where all times are in weeks. There is a penalty of $6,000 per week for every week the project extends beyond 25 weeks. What is the lowest total cost duration for completing this project?

-Use the Gantt chart and activity list to determine which resource has the greatest continual use.

Sketch a network and use it as an example as you discuss the four different logical relationships between activities.

-What is the late finish for activity D in the network shown in the diagram?

The AOA network described by this table needs:

Research has shown that, in general:

A project has the activity duration and cost information indicated in the table where all times are in weeks. What is the lowest total cost for completing this project in 33 weeks?

The AOA network described by this table needs:

Gantt charts cannot depict float.

Finish to start lags are the same as additional activity slack.

-Use the Gantt chart and the activity list to determine which resource is needed earliest in this project.

It costs $75 per day for each day that a construction crew is on site. The project manager determines that most activities can be crashed and has listed the crashing costs next to the minimum time for each activity. Use this information to determine the lowest cost for this project. All times given are in days.

Brook's Law states that the typical crashing decision to add more resources to an activity only delays the activity further.

Activities A and B have a finish to finish relationship and early start and finish times as shown. What is the result of incorporating a 4-day lag between activities C and B?
