Problem in distrbution center modeling

[Wingkins]

Dear sir,

let say i have 2 sets, the distribution center(DC)(index:i) and the
customers(C)(index :j), and now I want to introduce the binary
variables
Xij that will equal to 1 when customer j assigned to distribution i,
and
equal 0 when otherwise. How should I set the conditions at aimms?

Thank you

What's the questions exactly? I assume you're not asking us to
formulate your model, right :)

Cheers,
Marcel
