Developed by Sandia National Laboratories, the Support Enterprise Model (SEM) is an enterprise-scale M&S decision support tool that provides an integrated simulation of a worldwide sustainment system. 

According to Sandia, "SEM  is a discrete event simulation tool designed to model and simulate operation and support activities of a worldwide sustainment system. The general objective of SEM is to help characterize the sustainment system performance including supply, repair, and manufacturing activities over the entire life of the enterprise. To accomplish this objective the user defines and executes SEM simulations to generate statistical results characterizing the enterprise operations using different notional support and sustainment options. Results of those simulations are analyzed to make recommendations for best-case logistics system configurations that support required mission capabilities at the lowest possible cost. SEM is applicable in industries as diverse as defense, energy, aviation, and healthcare. SEM enables: 

  • Integrated modeling of supply chain and repair chain activities for a worldwide support system
  • Logistics modeling, analysis, optimization, and decision support of global operations
  • Calculation of system and support structure performance and cost metrics while accounting for uncertainty
  • Spares inventory and resource optimization on a global scale”
