Free Float and LAG

Hi Mohamad

Free float is the spare time available between finishing one task and starting another in the same logic sequence.

Lag is an artificial amount of time built into the logic to stop a task from starting or finishing when the natural logic says it should.

Use of Lags is not good planning practice unless it is to set curing period.

thanks mike actually i asked in awrong way , i know the difference but when u gonna to calculate in manually (i am doing this exersice coz i wanna to understand why i need to use zero free float constraint) so while u r calculation it manually in PDM for example its the same formula am i rite?

Mike,

Sell your one cylinder car and get something better. Same goes to limited functionality of old CPM, the absence of lag modeling when needed is as bad as its use when not appropiate.

Hi..

I think Lag is an offset or delay from an activity to its successor. This could be negative or positive.
