This book provides a broad overview of revenue management and examines this topic from different perspectives. It is divided into three major parts. The first part deals with issues related to business model changes; the second part deals with customer, market and marketing issues and the third part examines revenue management and related issues from various other perspectives.The book is dedicated to the theory and practice of revenue management. Although cost management tends to focus on expenditure, it is important to pay attention to revenue as well. If a company is unable to generate sufficient revenues, it will not be able to generate a profit no matter how hard it tries to reduce the costs, thereby threatening its long-term existence. For this reason, revenue management, along with cost management, is essential. In addition to costs, research on cost drivers has made progress in recent years. However, systematic research on revenue is still incomplete. There is thus a need for theoretical and empirical research on various issues related to revenue management and to systematize them.
