Interaction Modeling

One of important method of equipment support concept evaluation is distributed simulation technology. In the simulation federation development based on HLA/RTI，how to simplify the process of creating federate is an urgent job. This paper proposes an equipment support simulation federate automatically generating framework in order to solve equipment support concept evaluation on diverse level concept. It can be divided into six parts that is federate definition tools, federate interaction modeling tools, federate deploy modeling tools, FED document automated create tools, federate time management tools and EXE document automated create tools. Equipment support simulation federate automatically generating framework can reduce the workload of simulation system exploitation based on HLA by separating high lever service from bottom detail. The application of joint operations equipment support concept evaluation is illustrated. It testify the available and feasible of equipment support simulation federate automatically generating framework.

Replenishment At Sea

Replenishment at sea is essential for sustainment of naval operations away from home ports. This paper describes physics-based simulation of the transfer of solid payloads between two ships. For a given operational scenario, the simulation can determine whether events such as breakage of replenishment gear or immersion of payload in the ocean will occur. The simulation includes detailed modelling of the replenishment gear and ship motions. Distributed simulation using the High Level Architecture facilitates time management and data exchange among simulation components.

Optimistic Synchronization

With the widely application of High Level Architecture (HLA) standard that supports interoperability and reusability, correct understanding of time management and advance mechanism in HLA has been a concerning difficult problem in the field of distributed simulation. Aiming at the problem, the paper analyzed and compared difference between conservative time advance mechanism and optimistic time advance mechanism. The rollback manager was introduced to implement the optimistic time advance mechanism. The middleware was also applied to deal with the rollback process in simulation model. In order to make fully use of advantages of optimistic synchronization mechanism, Flash Queue Request (FQR) service that provided by HLA was used to arrive at an improved time advance algorithm.
