Independent Float Solution

STEP 0: Pre-Calculation Summary

Formula Used

independent_float = Free Float-Slack of an event
IF₀ = FF₀-s
This formula uses 2 Variables

Variables Used

Free Float- 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.
Slack of an event- 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.

STEP 1: Convert Input(s) to Base Unit

Free Float: 0 --> No Conversion Required
Slack of an event: 18 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

IF₀ = FF₀-s --> (0)-18

Evaluating ... ...

IF₀ = -18

STEP 3: Convert Result to Output's Unit

-18 --> No Conversion Required

FINAL ANSWER

-18 <-- Independent float

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).

How to Calculate Independent Float?

Independent Float calculator uses independent_float = Free Float-Slack of an event to calculate the Independent float, The Independent Float is the excess time available is preceding activity ends as late as possible and succeeding activity starts as early as possible. Here slack is tail event slack. Independent float and is denoted by IF₀ symbol.

How to calculate Independent Float using this online calculator? To use this online calculator for Independent Float, enter Free Float (FF₀) and Slack of an event (s) and hit the calculate button. Here is how the Independent Float calculation can be explained with given input values -> -18 = (0)-18.

FAQ

What is Independent Float?

The Independent Float is the excess time available is preceding activity ends as late as possible and succeeding activity starts as early as possible. Here slack is tail event slack and is represented as IF₀ = FF₀-s or independent_float = Free Float-Slack of an event. 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 and 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.

How to calculate Independent Float?

The Independent Float is the excess time available is preceding activity ends as late as possible and succeeding activity starts as early as possible. Here slack is tail event slack is calculated using independent_float = Free Float-Slack of an event. To calculate Independent Float, you need Free Float (FF₀) and Slack of an event (s). With our tool, you need to enter the respective value for Free Float and Slack of an event and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Independent float?

In this formula, Independent float uses Free Float and Slack of an event. We can use 1 other way(s) to calculate the same, which is/are as follows -

independent_float = Early Finish Time-Late Start Time-Activity time
