Categories of Publication

ORiON typically publishes papers in the following categories:

OR Success Stories: These 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: These might not be "success stories," but they emphasize novel approaches or describe pitfalls in the application of Operations Research.
OR Methodological Reviews: These survey new and potentially useful methodological developments aimed at Operations Research practitioners, especially in Southern Africa.
