product-form solution In probability theory, a product-form solution is a particularly efficient form of solution for determining some metric of a system with distinct sub-components, where the metric for the collection of components can be written as a product (mathem ...

where he has worked since, obtaining his Ph.D. in Computing Science in 1979 with a thesis titled "Representative queueing network models of computer systems in terms of time delay probability distributions" and lecturing since 1983. Current research interests include parallel algorithms, performance engineering, queueing theory, stochastic models and stochastic process algebra, particularly the application of RCAT to find product-form solutions. Harrison has coauthored two books, ''Functional Programming'' with Tony Field, and ''Performance Modelling of Communication Networks and Computer Architectures'' with Naresh Patel and published over 150 papers.
