Peter George Harrison (born 1951) is an Emeritus Professor of Computing Science at Imperial College London[3] known for the reversed compound agent theorem, which gives conditions for a stochastic network to have a product-form solution.
[4] After spending two years in industry, Harrison moved to Imperial College, London 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.
[5] 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.
[6] Harrison has coauthored two books, Functional Programming with Tony Field,[7] and Performance Modelling of Communication Networks and Computer Architectures with Naresh Patel[8] and published over 150 papers.
[10] Via Saharon Shelah and Dov Gabbay, Harrison has an Erdős number of 3.
