Standard +0.3 This is a resource levelling question requiring students to identify which histogram maintains the critical path while respecting the 2-worker constraint. It involves checking constraints rather than constructing a solution, and is a standard application of critical path analysis concepts with minimal calculation required.
A company undertakes a project which consists of 12 activities, \(A\), \(B\), \(C\), \(\ldots\), \(L\)
Each activity requires one worker.
The resource histogram below shows the duration of each activity.
Each activity begins at its earliest start time.
The path \(ADGJL\) is critical.
\includegraphics{figure_1}
The company only has two workers available to work on the project.
Which of the following could be a correctly levelled histogram?
Tick \((\checkmark)\) one box.
