System of Systems Analysis Toolset (SoSAT)

Developed by Sandia National Laboratories, the “SoSAT is a tool designed to model and simulate multi-echelon operations and support activities of a system-of-systems (SoS). It provides logistics analysts with the ability to define operational and support environments of a SoS, ascertain measures of platform and SoS-level performance effectiveness, and determine logistics support issues. As a stochastic simulation, SoSAT characterizes sensitivity changes to all platforms, support systems, processes, and decision rules as well as platform reliability and maintainability (R&M) properties. It is designed to be a robust decision support tool for evaluating readiness and sustainment of systems, including consumables and maintenance operations. SoSAT is applicable in diverse industries such as defense, energy, aviation, and healthcare.”

According to Sandia, "SoSAT enables: 

• A unique approach to SoS analysis
• Multiple user-definable performance metrics
• Modeling system interdependencies and shared functionality
• Performance measurements of functionally interdependent SoS
• SoS trade study modeling, analysis, and performance assessment
• Reliability and functional availability analysis"
