Hybrid Simulation Models of Computer Systems
Schwetman
Abstract
| A hybrid model is defined to be a two-phase model in which discrete
event simulation is used to implement the first phase and mathematical
modeling is used to approximate the behaviour of the second phase. The
goal of this approach to modeling is for the observed results of the
hybrid model to be a good approximation to the results of an equivalent
simulation-only model but at a significant reduction in computational
effort.

Notes
| Perhaps the first example of the hybrid simulation method. It is applied to
the simulation of a computer system - arrival and processing of jobs at a
CPU - rather than a network. Schwetman uses the decomposition variation -
some aspects are modeled analytically, the use of short term resources
such as memory for instance, while long term processes, arrival of new jobs,
are modeled by discrete events.
