Operations Research and Cyber-Infrastructure is the companion
volume to the Eleventh INFORMS Computing Society Conference (ICS 2009),
held in Charleston, South Carolina, from January 11 to 13, 2009. It
includes 24 high-quality refereed research papers.
As always, the focus of interest for ICS is the interface between
Operations Research and Computer Science, and the papers in this volume
reflect that interest. This is naturally an evolving area as
computational power increases rapidly while decreasing in cost even more
quickly. The papers included here illustrate the wide range of topics at
this interface. For convenience, they are grouped in broad categories
and subcategories. There are three papers on modeling, reflecting the
impact of recent development in computing on that area. Eight papers are
on optimization (three on integer programming, two on heuristics, and
three on general topics, of which two involve stochastic/probabilistic
processes). Finally, there are thirteen papers on applications (three on
the conference theme of cyber-infrastructure, four on routing, and six
on other interesting topics). Several of the papers could be classified
in more than one way, reflecting the interactions between these topic
areas.
