报告摘要：

Airline Seat Allocation under Competition with Dependent Demands

Michael Li Zhi-Feng

Nanyang Business School, Nanyang Technological University

We  examine a seat allocation game between two airlines for flights with  two fares with dependent random demands. The strategic variable of this  game is each airline’s booking limit for the low fare. We have shown  that there exists an equilibrium booking strategy such that both  airlines will protect the same number of seats for the full fare and the  total number of seats available for the discount fare under competition  is smaller than the total number of seats that would be available if  the two airlines collude. A numerical example is used to illustrate the  equilibrium solutions and to examine the impact of the capacity shares  and the level of dependency between random demands. We conclude with  some open questions for further research.

A Reservation Policy for Medical Diagnostic Resource Allocation

Medical  diagnostic facilities such as CT or MRI, which form the critical part  of a comprehensive health care system, play an important role in the  proper diagnosis and timely treatment of diseases. Hospital managers are  under great pressure to manage such facilities efficiently and  effectively. This problem is critical in China, especially in the  general hospitals. In this paper, we study the resource allocation  problem of medical diagnostic facilities accessed by three types of  patients. Both inpatients and outpatients have to make appointments in  advance and emergency patients walk in directly. We formulate a dynamic  programming model of the resource allocation problem and study the  structural properties, based on which we fully characterize the optimal  reservation policy. An upper-bound to the DP value is obtained from a  standard ``hind-sight'' optimal argument, and is shown to be  asymptotically optimal. A lower-bound to the DP is created through three  independent newsvendor problems constrained by the capacity. The gap  between the upper-bound and lower-bound is explicitly quantified. We  then propose and compare three heuristic policies analytically. The  process and data of West China Hospital are used for analysis and  implementation. Numerical studies show that the performance of bounds  works very well and our heuristic policy outperforms the hospital's  baseline policy significantly.

Dynamic Nonlinear Pricing of Inventories over Finite Sales Horizons

We  present three dynamic pricing models in a setting where customers can  be incentivized to purchase multiple units. We assume a finite sales  horizon with a sunk investment in limited inventories, where customer  demands form a compound Poisson process that is price dependent. The  dynamic linear pricing (DLP) model charges a uniform price that depends  on the time-to-go and the remaining capacity. The dynamic package  pricing (DPP) model allows complete freedom in pricing different package  sizes. We also study dynamic block pricing (DBP) as an intermediate  scheme where prices are linear within each block. For all models, we  present analysis and structural results and compare their performance,  both theoretically and numerically. We find that the potential revenue  improvement of DPP over DLP ranges from 30% to 90%, depending on the  purchase quantity. Our numerical studies reveal that DBP achieves more  than 97% of the revenues from DPP.
