Subscript for time based variabel

[nidfar]

Hi,
can i make a time based variabel for subscript? i wanna try critical path method for project in vensim.
for example, i have 3 scope for my project: design, engineering, and installation.
the duration:
design 30 weeks, engineering 15 weeks, installation 35 weeks.
i wanna put these variabel into subscript feature, can vensim afford it?

any adviced are welcome, thank you.

You need Vensim Pro or DSS for subscripts.

There's a subscripted project model in the User Guide:

It's not really a comprehensive project model, but it does show how to set up the subscripting.

Unless you do some really arcane stuff, you won't really be doing CPM in Vensim (or any other SD tool). But that's kind of the point: CPM ignores the cross-stage rework cycle, partial concurrency, and other effects, which is why it's useful to move away from that view of things.
