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. 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. In addition to this, SCS also created The McLeod Modeling and Simulation Network (M&SNet) in 2003, which is a consortium of co-operating independent organizations active in professionalism, research, education, and knowledge dissemination in the modeling and simulation (M&S) domain. M&SNet aims to provide an organizational structure that will serve to integrate and enrich, within its organizations, modeling and simulation activities throughout the world. The M&SNet provides a framework within which organizations interested in M&S can interact, share expertise, and work on problems of common interest.
