Jade, regarding your RF for status report. I picked up a 2nd edition of "Modeling and Analysis Using Q-Gert Networks" by A. Alan b. Pritsker (c)1979 (for $10 from
http://www.powells.com/technicalbooks ). Pritsker describes the iterative development of Q-GERT through hundreds of varied projects --consistent with dotProject's requirement of application to a variety of projects.
Chapter 6 discusses integrating various statistical distributions in the Fortran IV program. The program is not listed, but the purpose and requirements of routines are described --as well as variables/fields. In line with Jade's model, he designates min and max slack-time fields as overall time duration of activity instead of (my proposal of) time difference (ie max duration less min duration) where min is the estimate value. Of course I'm just skipping through the book at this point. Perhaps he's just emphasizing the statistics calculations in this part... I have much more reading to do.
