Celebrating the 10th Simulation Workshop: the story of the conference series

March 2021 saw the running of the 10th Operational Research Society Simulation Workshop (SW), albeit delayed by a year due to the Covid-19 pandemic. It is over 20 years since the planning commenced for the very first SW which took place in Birmingham in March 2002. To mark this occasion, this article presents a short history of the conference including the events that led up to the first conference, details of the first SW, a summary of all 10 SWs, and how all this led to the creation of the Journal of Simulation. As founders of the conference series we provide our personal reflections on these events
