Re: different output issues

Hi,

I will post the mdl soon.

What I see that when we water demand in A and B,
there many round-up numbers that let to
different levels of main reservoir.

For instance, when I combine water demand A and water demand B,
there are several round-up numbers, lead to different reservoir water levels

different output issues

Dear,

I attach my model.

The 1st model separates outflow to A and B
and the 2nd one combines flow A and B.
My question is why the main reservoir levels are different
for different models?

three consecutive values

Hi,

I want to set "fluctuated price1" to be "1" as long as "randomized prices" are not zero in three-consecutive time.
(otherwise set "fluctuated price1" to be "0" )

What shall I do?

I attach the model.
