Bob,

Thank you very much anyway.
Hope my saving let me buy the latest version this year

Thank you Bob, I downloaded the model and it makes perfect sense now (refereing to the structure and the inputs). Just one observation: when I try to run it a compilation error appears: "Missing a closing parenthesis on a lookup table call" The cursor points here(*): var over time= VECTOR ...

Thank you very much Bob, I am not sure of how to use Vector lookups and I was hoping that maybe there was another possibility of not using this function but I am seeing that there is not much a choise. If you can help me with this, please comment on a thread I post today about Lookup functions.... I...

Hello! I was wondering if anybody has a model who has a vector lookup function included that can upload because I tried to use this function in one of my models but I have not figured out how it works and the literature (webpages and manual) I revised have not helped me.. yet.. I would really apprec...

Thank you guys!! I am going to implement them right now in my model (in a smaller intance), but before it brings me another question: If I want to assign one value for each day to a variable (and my model runs 120 days) I dont know if there is a faster way to do it. The values itself are not importa...

Hello I have a very simple question: ¿How do I make a variable to take certain values over time? For example: Variable 1 = 5 Variable 2 = 6 Variable 3 = 10 Variable A = during the first period of simulation (e.g. 1 day) takes the value of Variable 1 (5), during the second interval takes the value of...

JJ, Thank you very much for your commentaries and for the example that you attached. My model is somehow similar to yours because in mine (a brief model is attached to this message) my goal is to minimize all the work that is still to be done in every step (in red). In my initial scenario I suppose ...

Hello to everyone, I am trying to use the policy optimization tool but I do not have valid parameters to use (I belive that it is because I have the "not valid optimization instructions found" error). I am not sure but I think that the only valid parameters are constants. The issue is that...

Thanks Bob for the suggestion. I think I am not being clear about my model. Basically the model try to simulate how the employees become busy (Level orange) when there is work to be done. On the contrary, if there is not work to be done, they become "not busy" (level red). So the flows tha...

Hello to everyone, I sincerely hope that you can help me with some issues that I have trying to use Vensim optimization tool for my employee´s scheduling activity model. Briefly, the situation is this: I´m doing a simulation model for my thesis about a process done in an invented factory. Here, ther...
