Slack of Event given Independent Float Solution

STEP 0: Pre-Calculation Summary

Formula Used

Slack of an Event = Free Float-Independent Float
S = FF₀-IF₀
This formula uses 3 Variables

Variables Used

Slack of an Event - (Measured in Second) - Slack of an Event in a network is the difference between the latest event time and the earliest event time at its terminal point or node.
Free Float - (Measured in Second) - Free Float is the period by which an activity can shift in its timing without affecting the early start of any succeeding activity or event.
Independent Float - (Measured in Second) - Independent Float is that portion of the total float within which an activity can be delayed to start without affecting the float of the preceding activities.

STEP 1: Convert Input(s) to Base Unit

Free Float: 18 Day --> 1555200 Second (Check conversion here)
Independent Float: 12 Day --> 1036800 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

S = FF₀-IF₀ --> 1555200-1036800

What is Independent Float?

Independent Float is defined as the amount of time an activity's start time can be delayed without affecting the earliest start time of any successors. So independent float is the delay in any project tasks that have no bearing on the early finish date of the project.

What is Tail Event Slack?

The Tail Event Slack of an activity in a network is the slack at the tail (or starting point) of an activity. In other words, tail event slack of an activity in a network is the difference between the latest event time and the earliest event time at its tail (or starting point or node).
