ORiON https://www.ajol.info/index.php/orion <p><em>ORiON</em> is the official journal of the Operations Research Society of South Africa (ORSSA) and is published biannually. Papers in the following categories are typically published in <em>ORiON</em>: • Development of New Theory, which may be useful to Operations Research practitioners, or which may lead to the introduction of new methodologies or techniques. • OR Success Stories, which describe demonstrably successful applications of Operations Research within the Southern African context (at the developing / developed economy interface) or similar environments elsewhere. • OR Case Studies, which might not be “success stories,” but which emphasize novel approaches or describe pitfalls in the application of Operations Research. • OR Methodological Reviews, which survey new and potentially useful methodological developments, aimed at Operations Research practitioners especially in Southern Africa. The above list is by no means exhaustive.</p><p>More information about the journal can be found at <a title="http://orion.journals.ac.za/pub" href="http://orion.journals.ac.za/pub" target="_blank">http://orion.journals.ac.za/pub</a> and <a title="http://www.orssa.org.za/wiki/pmwiki.php?n=Main.ORiON" href="http://www.orssa.org.za/wiki/pmwiki.php?n=Main.ORiON" target="_blank">http://www.orssa.org.za/wiki/pmwiki.php?n=Main.ORiON</a></p><p><span style="text-decoration: underline;"><strong>Online Submissions:</strong></span> Authors of new submissions are requested to use ORiON's online submission system.
