The following activities are part of a project to be scheduled using CPM:
The critical route is discovered by estimating the time it takes to complete activities from start to finish or the maximum duration of dependent activities.
The ES of activity A will be a zero. A's EF is determined by combining its time of the tasks (6) as well as ES (0)
As a result, A's EF would be 6+0=6
The ES of task A would become the ES of the activity that follows it. Another ES, as well as EF, are derived in the same way.
For activity E, whose predecessors are B as well as D, ES will become the largest of EF of both B as well as D. Since the EF of B is 9, as well as the D, is 15, the ES of E seems to be 15.
The LS is measured by subtraction of activity duration from LF.
Use the given principles to determine the ES, EF, LS, as well as LF levels for the following project activities:
Determine the value of slack using the formula given below:
Slack = LS – ES
The value of slack is calculated given below:
