hi every one, 

I am a beginner in OPL and  I dont know how to define not equal in constrints. I use <> but it gives me an error of an unexpecting >.

and I want to program the constraints that have been attached but I do nt know how to write the index. it gives me error when I write it as it follows:

forall (j in 1..J)

s[j][r[j]]=sum (i in 1..W)(e[[j][i][r[j]+1]]- e[j][i][r[j]] );

can you help me please?

or is there any reference that i can study to know?

thank you
