Stochastic Operations Research (SOR)
Stochastic Operations Research
The research program Stochastic Operations Research focuses on systems that operate in the presence of randomness. It aims at developing mathematical models and methods for the design, analysis, optimization and control of such systems. A large part of the research effort is devoted to queueing theory and the analysis of random walks related to it. Some of the queueing research is of a fundamental nature, and much of it is inspired by problems in production and logistics and in computer-communication systems.
The group has several PhD students and postdocs, in particular in the latter area via an ERC grant (Van Leeuwaarden) and a TOP subsidy (Borst and Van Leeuwaarden). The group is intertwined with the Queueing and Performance Analysis project of the European research institute Eurandom.
