PERT-CPM BasicSolution is a starting model for construction projects, you can help me to improve it
This model has 4 activities:
- activities duration are initialized by stocks named 'Duration - Activity...'
- activities are represented by flows
When an activity starts, it decreases the corresponding stock, when the stock = 0, the activity stops.
In each flow, this type of code controls the start/stop of the activity:
IF p:vfrom<=0 THEN RETURN // p:vfrom = value of the source stock of the flow = Duration of the activity
IF Svalue("Days") <=0 THEN RETURN //if value of the stock Days <=0, the project is not started
or IF Fvalue("Commercial Customer") >0 THEN RETURN // if an activity (Commer...) is not ended, the current activity doesn't start
y=1 //the return value of the action of the flow decreases 1 day from the source stock of the flow ( Duration of the activity)
The stock Days displays the number of past days
The stock Duration-Marketing-Business Development displays the sum of all the durations
