Many new technical systems are distributed systems that involve complex interaction between humans and machines, which notably reduces their usability. The properties of Agent Based Simulation make it especially suitable for simulating this kind of system. However, it is necessary to define new middleware solutions that allow the connection of simulation and visualization software. This paper describes the results achieved from a multiagent-based middleware for the behavior simulation and visualization of agents. The middleware modules presented in this study allow a complete integration of technologies for the development of Multiagent Systems and Agent Based Simulation, the construction of virtual organizations of agents, and the connection to external modules that represent the entities of the agents
