In this paper we discuss an elementary net (EN) based model in which there are 3 levels named L1, L2, L3 respectively. In the level L1 on an EN the arcs, events and places can be interpreted in order to use it easily in system design. In L2, it is also a graphic model, each node has their own implementation by EN. More precisely there are two kinds of function nodes and two interface nodes in it. The function nodes have `parallel', `choice', `send', and `receive' for the nodes of interface. Using L2 a three processors cooperative computing system is introduced to demonstrate the advantages of L2. Considering the design complexity, a very high level model L3 which is a model more higher than L2, is established, in which there are three useful macros called `synchronization', `decision' and `guarded'. Modelling a two processors system by L3 makes the model to have more sense
