Re: Automated multiple simulations in PLE+?
Thank you so much for your replies! I truly appreciate the guidance. I'll endeavor to put @tomfid's solution into practice. As a doctoral student without external funding, my resources are limited, and I regret to inform you that I'm unable to acquire the DSS version due to financial constraints. Yo...

Automated multiple simulations in PLE+?
Is it possible to perform multiple simulations of a model at once in VENSIM PLE+?
I mean, I have a model that includes several random variables of the RANDOM UNIFORM type. I'd like to know if it's possible to obtain multiple runs of the model to obtain different results.
Thank you very much

Chart with two axes (primary and secondary) consult
Is it possible in Vensim to configure a chart where we include two variables of different scales to include a secondary axis - with a different scale - that allows for better interpretation?
If there is the possibility, how do I implement it?
Thank you very much.

Re: Help me with Staff model
Thank you very much, you're right. You've made me reflect. The effect I'm trying to capture with "people quitting" is that individuals leave the course at any time from the beginning of its delivery (either because they don't like the course or because they found a better opportunity). And...

Help me with Staff model
Dear,
Could you help me correct this model?
In the simulation, I'm getting negative values in the "Training" level variable, and I need it to always have values greater than or equal to 0.
I've tried several fixes but haven't been able to balance it.
Thank you very much.

Re: Continuos or discrete variables?
Thank you very much for the detailed response. I understand your argument and Forrester's regarding the loss of certain complexity when discretizing, and I am reflecting on its implications.

Continuos or discrete variables?
What is the most suitable approach for VENSIM and for the essence of SD? Should we model discrete variables (such as the number of employees in a company) as continuous or discrete variables? When considering the amount of personnel in a company, we never have fractions of people as employees; we al...

Dear experts, I need model a variable that maintains a constant value (but obtained from a random variable) that lasts for 365 days and repeats periodically every 365 days. What I want to simulate is a constant but random value every 365 days, and that the function keeps that value constant for 365 ...

Thank you! For example: I have one stock variable with dmnl units.
