This book develops a modeling framework to analyze the problem of
inventory management with alternative delivery times. The general
context considered here is that a seller replenishes its inventory in
fixed intervals and, between replenishments, allocates the limited
inventory to satisfy customers who are both price and delivery-time
sensitive. On the demand side, customers have heterogeneous
delivery-time requirements and choose either spot or late delivery. This
theoretical modeling captures the essence of real-world business
practices such as the delivery time market segmentation strategy adopted
by automobile dealerships in China and many other similar examples. The
book focuses on the seller's optimal inventory replenishment and demand
fulfillment policies, and our results provide managerial insights into
the merits of flexible delivery-time options. Similar applications such
as the group-buying mechanism are also examined. The main mathematical
tool used in theoretical analysis is dynamic programming. This book is
written for students, researchers, and practitioners in the areas of
operations management and industrial engineering who are interested in
understanding the rationale of flexible delivery times and designing
successful applications.
