This paper presents an optimization of transportation networks using petri holonic enterprises. The development work is leaving the role and functions of holonic enterprise and then implementing a Petri net, which is designed to optimize transport in such an enterprise. The research purpose is to provide industrial users means to make decisions, to obtain short-term forecasts and to be able to build one that will need mechanisms. For simulation using Visual Object Net ++, because it is relatively easy to use, can be used for complex systems and the literature it is recommended for systems with discrete events. In the development of the paper, the holons are considered to be unitary entities represented by a number of system processes running on stations defined on the basis of a predetermined algorithm.
