摘要

Operations Research uses quantitative models to analyze and predict the behavior of systems, and to provide information for decision makers. Two key concepts in Operations Research are Optimization and Uncertainty. Uncertainty is emphasized in Operations Research that could be called "Stochastic Operations Research" in which uncertainty is described by stochastic models. After the success of the First International Workshop on Recent Advances in Stochastic Operations Research (2005 RASOR Canmore), Canmore, Alberta, Canada, on August 25-26, 2005, the Second International Workshop on Recent Advances in Stochastic Operations Research (2007 RASOR Nanzan) was held under the support by Nanzan University, Nagoya, Japan, on March 5-6, 2007, where 43 papers were presented.
