Question $5$

You are the project manager for the project below. You have two civil engineers to do the tasks. The Gantt chart after the initial phase of planning shows the project will finish in $30$ days. The numbers in the Gantt chart below represent the number of civil engineers needed for the task. $($The Gantt chart is displayed in increments of $5$ days$).$

This is a resource$-$constrained problem, but we can make it work in $30$ days.

This is a resource$-$constrained problem, and if we don't get more resources, then after leveling the project will be delayed by $10$ days.

This is a resource$-$constrained problem, and if we don't get more resources, then after leveling the project will be delayed by $15$ days.

This is a resource$-$constrained problem, and if we don't get more resources, then after leveling the project will be delayed by $20$ days.
