We will now use a simple example to illustrate how to addressing resource over-allocations.

The precedence relations and number of engineers required to complete a project are given in the table attached here. Leveling-table

Construct an early start Gantt chart and identify the critical path.

Calculate and chart the resource loading profile required to complete the project for an early start schedule.

Assume that 10 engineers are assigned to work on the project till it is finished. Is the schedule attainable?

•What is the earliest time the project can be finished if there are only 10 engineers?

•What about if there are 12 engineers?

•How many engineers will be needed to meet the original schedule?
