The International Symposium on
Military Operational Research




Welcome to ISMOR

ISMOR, the world's foremost international conference on defence and security operational research, was founded in 1984 by the late Professor Ronnie Shephard, who at that time held the chair of operational research (OR) at the UK's Royal Military College of Science at Shrivenham.   It has been held annually ever since.

ISMOR is now managed by the Operational Research Society, with the Society's Defence Special Interest Group playing a key role.

ISMOR is officially endorsed and sponsored by the UK Ministry of Defence and strong support is also provided by the Military Operations Research Society in the US.

Papers and presentations from earlier symposia are available online.

The ISMOR website also hosts other online resources likely to be of interest to the defence and security analysis community.
