#### Abstract

Scene Transition Nets (STN) are graphical modeling tools and simulators for discrete-continuous hybrid systems. Designers have previously built complex STN models of large-scale systems on the basis of a single aspect. However, many large-scale systems consist of several sub-systems designed for different purposes and based on different aspects. In addition, these subsystems are complexly intertwined with each one another. For verifying the behavior of such complex systems in simulations, it is necessary to construct multiple STN models of the subsystems, integrate them by taking into account the relationships among the subsystems, and simulate them in parallel. Kawata has proposed ”multi-aspect modelingh using STNs in order to realize above-mentioned modeling concepts. However, the interaction of the sub-STN models with other models is difficult according to the basic STN concepts. This shortcoming interferes with the practical implementation of multi-aspect modeling. The authors overcome this shortcoming by enabling the sharing of the state variables of the actors (actors correspond to tokens in Petri nets). Called ”actor-link”, the simple concept enables to construct complex layered and parallel structures of STNs and perform multi-aspect modeling. The experimental results for the modeling and simulation of certain complex industrial systems demonstrate the effectiveness of the proposed method and simulation tool.
