Solve the arrow diagram network shown below. Interfering Float (IF) = Total Float (TF) - Free Float (FF) The critical path pf the project contains all the activities with Total Float (TF) equal to zero (0). An activity which has free float can more readily be arranged to be performed at different times than one which is subject only to interfering float, as the effect on succeeding activities need not be considered. Interfering Float That part of the total float which remains after free float has been deducted is the interfering float.

Interfering float The amount of time a task can be delayed without pushing a project past its committed deadline is Interfering Float. Once this has been done, the total float of any activity is simply the difference between the latest finishing time (LF) obtained from the backward pass and the earliest finishing time (EF) obtained. The term Float expresses flexibility that helps in such schedule adjustments. Edit: a local pilot has actually crashed in the cove in the past (without injuries) and voluntarily gave up their license. B. 1) (3. interfering (shared) float d. Note: In case a negative value is obtained, it is taken as zero. Float is the amount of time by which an activity can be delayed or extended. Interfering Float = Total Float – Free Float Independent Float (INDF) Interfering Float is the maximum amount of time an activity can be delayed without delaying the early start of the succeeding activities and without being affected by the allowable delay of any predecessor activity.
