Activity Relations

In the Open Standard

Activity Relations as we all know are listed below

1. FS-Finish-to-Start
2. SS-Start-to-Start
3. FF-Finish-to-Finish
4. SF-Start-to-Finish--> which im not using in my schedule.

Why dont we develop relations like

Act A

---> SS Lag= after 50% of Act A

Act B

Because the start of most activities will not depend on the start of predecessor activity but depend if that predecessor activity completed 50% already.

Is that logical?

Thanx and more power,
Francis

    Francis,

    I don’t mean to speak for Vladimir, but I was impressed recently to discover (in another thread) that apparently Spider Project has the functionality to make lags based either in time or in work completed. (That’s if I understood clearly!) I agree that this would be a useful feature.

    I’m sure that Vladimir will be along to explain when he has a minute.

    Francis,
    Having groovy features in the software is one thing.
    Using them in CPM modeling is quite another.
    See Mike’s abominations topic.
    You have been a member of PPP since February. Welcome, but you are asking questions that have been flogged to death here many times. How about read all of that first?

    Hi Francis,
    yes, Spider Project supports volume and time lags.
    Volume Lag can be set as the number of physical units (m3, tons, etc.) or percent of the previous activity volume (quantity) of work.
    You can download Spider Project Demo from http://www.spiderproject.ru/demo_e.php
    It has 40 activities per project restriction and no other constraints.
    If you will have questions don’t hesitate to ask them, I will be glad to answer. Especially if you will not find in Spider Project some feature that you need - I will explain where to look.
