Variants of CSXMS Models
Several different variants of the basic CSXMS model have now been
and this page provides an overview of these. A report is being
which will document them in more detail, but that is not yet available,
and when it is it will be extremely detailed - perhaps much more so
many readers might want at first. The other aspects of CSXMS
for which there are separate pages, are as follows.
- The basic introduction to them, which
at least a background to the issues described here.
- The papers and other
them, which describe at least some of these different variants in more
The basic CSXMS model was developed from an earlier proposal by Barnard
and Whitworth, but this was not developed to a point where it was
to compute the input-output relationship for a system, and so it is
whether it should really be counted as a variant. Since it is
as background, though, a brief description of it is included
Thus, the main variants of the basic model that are covered here are as
The Barnard and Whitworth Model
