Stellar is a real-time system which aggregates and correlates alerts from heterogeneous network defense systems, building scenarios and estimating the security risk of the entire scenario. Prior work considered Stellar scenario formation; in this paper we explore the advantages provided by using scenario context to assess the risk of actions occurring on a(More)
SimYard is a stochastic shipyard simulation tool designed to evaluate the labor costs of executing different schedules in a shipyard production environment. SimYard simulates common production problems such as task delays and labor shortages. A simulated floor manager reacts to problems as they arise. Repeatedly simulating multiple schedules allows the user(More)

The ARGOS scheduling system is designed to reduce labor costs in large facilities such as shipyards. Theoretical results suggest that ARGOS is capable of reducing total labor costs for a large ship construction project by between 7 and 14 percent. SimYard is a stochastic shipyard simulation tool that can model a wide variety of shipyard production(More)
