JESS supports all the simulation stages from constructing the models to experimenting with them. The basis of JESS is an object-oriented formal model and a specification language that supports several levels of model description with an E-net specification. The Internet-orientation of the system allows to create models executed on a remote server and makes these models available from any point of the network. This article contains descriptions of the JESS simulation technique and the implementation of its Internet properties.enText/Conference Paper1617-5468
