Lists of Wartime Operational Research Groups June 24, 2011

As far as I know, no one has ever assembled a list of all World War II-era operational research groups.  Some of this information is available in published resources; other bits are from archival research.  Bullet points under particular groups represent changes of name.  Dates can be a little fuzzy, since they can refer to when a group was formally approved, or when it started work; or when one or two people arrived at a location, only later to grow and be formally recognized.  I have tried to date things to when work actually began, but have probably not always been consistent in this.  Some form of this list will likely appear in my book, but as a general service in the meantime, here it is:

Sources on American Groups

Charles R. Shrader, History of Operations Research in the United States Army, Vol. I: 1942-1962 (2006) is a good resource for quick institutional history.  Erik P. Rau, “Combat Scientists: The Emergence of Operations Research in the United States during World War II” PhD dissertation, 1999, has the most detailed cross-service, behind-the-scenes information on how groups were conceived and set up.

*These sections were more field units of the Office of Scientific Research and Development (akin to the British Branch of the MIT Radiation Laboratory) than OR sections; however, the American army designated the Central Pacific Group (housed in Hawaii) an “operational research section”; therefore it, and a companion section based in Australia, are listed here for the sake of completeness.

Have you stumbled across any OR groups in MI6 and other clandestine services?

2. Will Thomas - June 24, 2011

Hi Charles — certainly not during the war. At that time OR was explicitly understood to refer to military operations; so, things like bomb damage surveys conducted by the UK Ministry of Home Security, though often mentioned retrospectively (and, to an extent, at the time) with OR work, were not “OR” per se. At any rate, as far as I know, there wasn’t even anything similar going on in the clandestine services, though I would be glad to learn I’m wrong about that.

After the war is another matter, since “OR” started to have a more general connotation, especially in Britain. Not only do you get groups in NATO, I’ve run into mentions of an OR group in the Atomic Energy Commission, which I know very little about. I don’t know of any with the CIA, FBI, MI5/6, or such organizations, but I wouldn’t be surprised to learn of them, starting from the 1950s. In later periods, when OR was more of a strictly mathematical thing (as opposed to a more generic policy analysis thing), one finds them all over the place, albeit not usually in the sort of advisory role the groups listed above played.

Great Stuff! Thanks! The Ronnie Sheppard Fonds at Laurier University, Waterloo, Canada, are a treasure trove of Ops Research, which contain a great cross-section of files largely on armour, artillery effectiveness, battle studies, and morale. I have yet to mine my collected documents there, but will post later if the Canadian list can be fleshed out further.

4. Will Thomas - September 26, 2011

Thanks, Will, please do! I don’t have much information on the Canadian groups at all. I didn’t realize until very recently that the head of the Army group was J. Tuzo Wilson, who later became well-known for his role in establishing the theory of continental drift.
