6.5.3 An Approach to Generalising the State Space of a Distributed Missile Simulator

Steven Gordon, Lars Kristensen, Jonathan Billington
2001 INCOSE International Symposium  
For example, the state space of a detailed design model can be compared with that of an abstract design model to see if it preserves sequences of events.  ...  In this paper we outline an approach for obtaining a generalised state space of a distributed missile simulator.
