Dear friends,

I have a problem in my model. How can I write this equation? Can you help me, please?

Regards

If (x(i)-x(j))*cos(l)+(y(i)-y(j))*sin(l)<0 , d(i,j)=(-1)*((x(i)-x(j))*cos(l)+(y(i)-y(j))*sin(l))

else d(i,j)=(x(i)-x(j))*cos(l)+(y(i)-y(j))*sin(l)

Dear Ã–zlem,

Are you using binary variables in this model? Because you probably need binary variables in order to model this type of condition. The if condition could be replaced to wrote:
