how to convert a value into a random (affected by certain fa

so let's say there are three values (share 1 to 3), each is a fraction of one, all summed together are equal to one (1). Then I convert them into flight hours, with the value one (1) actually is equal to 800 hours. So the fraction 1/16 means it's 50 hours, 3/8 means 300 hours, and so on. Now I want ...

how to ensure the value of many variables is equal to XYZ?

Ok, what I'm doing is making more than one variables (up to 16 variables), each is a fraction of 1. I want to make sure that the program checks the value of all variables, so that when we run the model, we can make sure that the amount of values of all variables is equal to 1. How can we do that? Th...

Ok, I'll try to address my problems one at a time. I think some of them is more technical and Vensim-focused instead of general System Dynamics. Should I make a new thread in the Vensim subforum or should I just put it here?

LAUJJL, thank you very much. I appreciate it. I'll try to simplify it first, I'm also tweaking my model as I'm reading the Road Map. When I can get it "reduced" to a simple problem,I'll get back here :)

Once again, thanks!

Need help on Fractional Aircraft Ownership

Greetings, I am currently doing a research for my final assignment, about Fractional Aircraft Ownership(FAO). If anybody's curious, yes, I'm widhie's junior (she posted 2 years ago on the similar-but-different-perpective topic). Currently I'm working on the financial/economical side of the FAO. Here...
