Re: Optimization Constraints using non-constants, percentages summing to 1.0

In theory it will be a dashboard, like Venapps, but I'm not sure I have enough time to fully develop venapps, and in the mean while I've been developing simplified Views that just display Snythesim sliders for the select parameters I would like Users to engage with (inside of Vensim) which works for...

Re: Optimization Constraints using non-constants, percentages summing to 1.0

Hmm ok, I think I might be getting lost, and apologies for not posting the model - I can't share it outside of my organization unfortunately. As for the approach proposed that uses proportion calculations, I'm not sure I follow - so the input itself that I'd be asking for from a user would be the # ...

Re: Optimization Constraints using non-constants, percentages summing to 1.0

Thanks for such a prompt reply and I think it makes sense to me in principle. Would these be new variables I'd include? Where might I fold in these inputs (in the model, or just in the optimization tool?)

Optimization Constraints using non-constants, percentages summing to 1.0

Good morning! I've been self-learning vensim DSS working on a staffing optimization model in response to a disaster event, and am having trouble determining how to include policy optimization constraints that are not constant values, or in substitute - combining 3 constants into a single constraint....
