Generic Optimization mix model

Hi, I'm a Vensimuser and I'm having some trouble creating an optimization model. I wanted to know if maybe Ventity might be the solution. Right now I'm are trying to create a generic mix optimization model with the following features: - Multiple raw materials from multiple sources - Multiple plants ...

Re: Multiple variable inputs in an optimization model

Are there any other ways to go about applying a constraint? My concern is that the model is going to get significantly more complicated with the addition of things like multiple sources for different resources, multiple lines of production in each factory, multiple products made from each. The solut...

Re: Multiple variable inputs in an optimization model

Thank you both for your replies! I was able to create the model using subscripts for both the Source of a resource (3 different sources) and the Factory each goes to (6 different factories). I basically entered 18 different production figures and then 18 different per unit transportation costs. One ...

Multiple variable inputs in an optimization model

Hello, I'm new to vensim so I'd appreciate any help I can get with this model I'm trying to construct. Basically I'm are trying to optimize the allocation of a resource across factories so that transportation costs and minimized and production is accomplished in the most cost efficient way. Here's a...
