SEM: Enterprise Modeling of JSF Global Sustainment

The joint strike fighter (JSF) program is implementing a paradigm shift to a performance-based logistics environment for force sustainment. This approach produces the necessary levels of performance at a significantly reduced cost of ownership. The resulting logistics environment is multi-national, multi-echelon, and multi-service. The magnitude of the change in the support concept requires an enterprise-level model that can instill customer confidence in unproven alternatives to legacy approaches and capture investment/commitment to enable a profitable execution. The support enterprise model (SEM) was developed by Lockheed Martin to provide a consistent/accurate global view for support of strategic decisions during design/implementation of a JSF global sustainment solution. SEM is a discrete event simulation that allows analysts to define operational/support environment, ascertain measures of effectiveness for performance/cost metrics, and characterize sensitivity to changes in support system architecture, processes, and business approach as well as air vehicle reliability and maintainability characteristics
