Ventana software support forum

Hi,
my model should generate following behavior:
If there is a supply gap > 0 (it means demand > production) then the price should increase by a fixed value for the next two years (also if the supply gap will be negative in the following years; this should be not considered in the price change rate)

For Example:
At time 2: Supply Gap > 0 -> decision to increase price
At time 3: Supply Gap < 0 -> decision to decrease price
At time 4: Supply Gap <0 -> decision to decrease price
-> What I want: Price should increase between time 2 and time 4

Can you please help me with my problem?
Thanks in advance,
Sandra

The IF THEN ELSE function should do what you want.

Using for example "IF THEN ELSE(supplyGap >0, +200, -100)" would increase the price at time 2 BUT at time 3 (when supplyGap < 0) this condition will not allow the price to increase further. But I want to force the price increasing up until time 4 (even though the supplyGap is smaller than zero in this time period).

Maybe a combination of IF THEN ELSE and SAMPLE IF TRUE?

Another option would be to use a level to store the time at which the price increase started.

This seems like unrealistic logic for a real firm. Is this for some kind of discrete game decision or something like that?
