Object-oriented simulator of multi-agent system for temporally rich domains

An object-oriented implementation of a program simulator for a multiagent system (MAS) is described. The model of a MAS is hierarchical model, consisting of different levels, where each level contains clusters of agents. A paradigm of a blackboard is used for communication among agents, clusters, as well as levels. Petri nets with time tokens are used as a basic concept for this model. An example of the use of the object-oriented simulator in a dynamic scene analysis is given.
