This edited volume contains 16 research articles and presents recent and pressing issues in stochastic processes, control theory, differential games, optimization, and their applications in finance, manufacturing, queueing networks, and climate control. One of the salient features is that the book is highly multi-disciplinary. Another distinct characteristic of the book is that all papers are motivated by applications in which optimization, control, and stochastics are inseparable. This book will be a timely addition to the literature and will be of interest to people working in the aforementioned fields. Most importantly, this volume is dedicated to Professor Suresh Sethi on the occasion of his 60th birthday, in view of his distinguished career, his contributions and achievements, and his influence on the areas of control theory and applications, operations research, and management science, as well as his dedication to the scientific community.
