[Cmpl] Convert GMPL to CMPL

[Schroeder, Rob]

Hi,
I am trying to port a small roll assortment problem from GMPL to CMPL.  I am modelling it as an assignment problem for now.

I have a set of PRODUCTS with widths as defined in the parameter pWidth, and a set of parent ROLLS with width rWidth.  My set Rp is an indexed set of parent rolls that can be used to produce product p.

Here's what I use in GMPL:

set Rp{p in PRODUCTS} := {r in ROLLS : pWidth[p] <= rWidth[r]};

so Rp[p] will contain all the parent rolls that are wider than the width of product p.

I am trying to figure out how to replicate this in CMPL.

Any pointers will be apprecaited.

Regards,
Rob
