This paper describes how to combine the JADE agent platform with Repast-provided simulation functions for rapidly developing ail environment for the simulation of complex agent model. The main motivation collies from our requirements concerning the simulation of enterprise Value-Adding Networks, whose ultimate objective is to analyse management performance. JADE is useful for creating duel deploying a distributed agent; organisation modelling enterprise workflow model and supply chain network, as well as for system monitoring at the level of agents mid communications. Integrating dynamically human interaction during the simulation is relatively easy. Repast was developed is a. general purpose framework for agent based simulation with appropriate graphic interfaces. Their combination makes it, possible to construct complex model of multi-agent organisation whose execution states can be observed front users and the global simulation results can be used for performance analysis. Their extension and composition mechanisms are described using a. case study of a manufacturing enterprise.
