The Society for Modeling & Simulation International (SCS), was established in 1952 as a nonprofit, volunteer-driven corporation called Simulation Councils, Inc. Simulation Councils, Inc. became The Society for Computer Simulation which is where we derived the acronym SCS. Today, we still keep the familiar SCS acronym as a part of our identity, but have given it a new and more relevant meaning: Simulate, Create, Serve. This SCS is not only who we are, but also who we serve.

SCS is the premier technical Society dedicated to advancing the use of modeling & simulation to solve real-world problems; devoted to the advancement of simulation and allied computer arts in all fields; and committed to facilitating communication among professionals in the field of simulation. To this end, SCS organizes meetings, sponsors and co-sponsors national and international conferences, and publishes the SIMULATION: Transactions of The Society for Modeling and Simulation International and the Journal of Defense Modeling and Simulation magazines.

The society is headquartered in San Diego, CA, and is managed by the executive director.
