A large class of systems being developed has both continuous time and discrete time behavior. In fact, any system that interacts with physical world falls in that class. Chemical, Automotive, Military, Aerospace are areas most frequently mentioned in this respect. To model such systems successfully and to get accurate and reliable results from simulation experiments one needs an executable language naturally describing hybrid behavior, and a simulation engine capable of simulating discrete events interleaved with continuous time processes. Additional problems arise with simulating hybrid systems in a distributed environment.
In the paper we present AnyLogic, a tool for modeling and simulation of hybrid systems and a way of HLA support integration in the tool simulation engine. To demonstrate AnyLogic ability to model and simulate hybrid systems, we present a simple example – two tanks problem. We examine problems aroused with distributed simulation of this system in AnyLogic using HLA.
