Ventana software support forum

Hi every one
I have a question about vensim:
I have use the condition function that if X in the time series=Max, then X+b, X
X is the number in the time step
How i can do this?
the attached pic my concept
thanks a lot

If N is a proxy for time here, there are two answers.

1. If the maximum is taken over all time, this is acausal (except at the end of the run), i.e. it implies knowledge of the future, which is impossible both in reality and in the model.

2. If what you mean by MAX is the largest value encountered so far at time t, then it's possible. You could do the following:

maximum x = SAMPLE IF TRUE( x > maximum x, x, x)
y = IF THEN ELSE( x >= maximum x, x+b, x )

Hello
