Abstract
This paper is concerned with the modeling and simulation of extremely large networks. We derive a timeβdependent diffusionβconvection partial differential equation, the solution of which captures the global characteristics of a stochastic network model. Continuum modeling provides a powerful way to deal with the number of components in large networks and opens up the use of highly sophisticated mathematical tools such as adaptive finite element methods. This, in turn, makes it possible to carry outβwith reasonable computational burden even for very large systemsβnetwork performance evaluation and prototyping, network design, systematic parameter studies, and optimization of network characteristics.

The objective of this article is to describe heuristic solutions to the problem of modeling inventories at each node of a large network in the context of a computer simulation model of that network. The heuristic solutions are compared with the mathematical solution which is too unwieldy for use in
We consider very large periodic trusses called lattice structures. In classical calculus, the periodic truss character and its global geometry are forgotten. With the homogenization method that we have developed, the lattice is replaced by a continuum model which approaches, in a certain sense, the
