Hi,

I was modeling my model using OPL. I face two problems and struck thereby to proceed.
1. I dont know how to use if else loop. For example, I have one parameter called power.... I need to define the values based on different links used....for this if else statement will be helpful. But I could not do a normal way since its throwing error.

2. In the constraints section, I am getting error "circular dependency declaring "Num" . I dont have a clue how to sort out this error.

I kindly request to help you.
Thanks!!!!

Hi,

1) did you check Conditional statements in OPL ?

Conditional expressions may also be useful to you
'expressed like this:
(condition)?thenExpr : elseExpr
where condition is a ground condition with no decision variable. If condition is true, the condition evaluates to thenExpr ; otherwise, it evaluates to elseExpr."

2) when declaring "Num" can you check that the expression you're using doesn't refer to "Num" itself?

Hope this helps
