Developed by Sandia National Laboratories, the Whole System Trades Analysis Tool (WSTAT) is designed to enable decision support for system designs and exploration and evaluation of the complex trade space that exists between component-level design decisions and system-level stakeholder value areas (e.g. performance, investment cost, schedule risk, growth potential, operating cost). 

According to the tool developers, “WSTAT is a decision support tool that integrates subsystem models into a holistic system view, mapping critical design choices to consequences relevant to stakeholders. It is capable of solving highly complex optimization problems covering various technology areas and performance requirements while balancing costs, risk, and growth – in sufficiently short timeframes to support the various stages of a system’s modernization process. WSTAT was developed and applied in partnership with the US Army Program Executive Office for Ground Combat Systems to provide unprecedented analytical capability and application of systems engineering in system design.”
