Review Quotes: "This special book is mostly devoted to honoring one person, who, thanks to his activity and outstanding ideas, was able to influence many people involved in widely understood information engineering, marketing engineering, market design, and service science. ... Anyone familiar with Christof Weinhardt's achievements (papers, projects, events, seminars) should read this book for a closer look at his concepts, proposals, ideas, interesting thoughts, and research activities."
