The work described in this paper required a 3D surface representation where points on the surface were generated by a neural network.  ...  This initial example was chosen because: (i) analytic results for the multi-server queue are known; and (ii) this type of queueing system is often a sub-component of more complex simulation models.  ... 

An object-oriented modelling enviornment

T. W. Page, S. Berson, W. Cheng, R. R. Muntz
1989 SIGPLAN notices  
The impact that these two paradigms, logic and objects, have had on the design is discussed. Several example applications are presented to illustrate the extensibility of the system.  ...  Many tools and techniques exist for the modeling and analysis of computer and communication systems. These tools are often complex and tailored to a narrow range of problems.  ...  Acknowledgements The authors wish to acknowledge the contributions of Gary Rozenblat, Leana Golubchik, and Jon Edwards to the implementation of the Tangram modeling system.  ...

The Performance Evaluation of Embedded Communication Networks

Syed Misbahuddin,
2014 International Journal of Engineering Research  
With the induction of new features inside such networks, the number of messages will increase. The increase of messages may affect the network performance for a given network characteristics.  ...  Performance evaluation of a message based networks is therefore desired with increasing message load.
