舱位控制是航空客运收益管理中的一个核心问题,舱位控制分析可以较好地提高航空客运的收益。文章放弃传统舱位管理问题关于决策主体是"完全理性人"的假定,同时引入考虑后悔的无选择效用函数,构建基于后悔理论的舱位控制模型,并进行实证分析,确认了其实际有效性。 相似文献

通过实证方法研究了考虑旅客选择行为的多舱位等级动态定价决策问题。基于多元Logit选择模型,提出了考虑票价、售出数量、变更转签限制、退票费用限制和提前预订天数等因素的旅客选择行为模型,并结合航空公司历史运营数据使用马尔可夫蒙特卡洛方法对旅客到达率以及旅客选择行为模型中的属性参数进行了估计。在此基础上,构建了融合旅客到达率和旅客选择行为的多舱位等级动态定价决策模型,用以阐释考虑旅客选择行为的舱位等级最优价格决策过程,确定每个时期舱位等级的定价策略,评估基于旅客选择的定价策略相较于现行定价策略的收益改进。实证结果表明:当决策时间点临近航班出发日时,舱位等级价格会随之提高;在同一个决策时间点,舱位等级价格会随座位余量的减少而提高。相较于现行定价策略,基于旅客选择的定价策略预期收益提高了22.32%,证明了基于旅客选择的定价策略在现实环境中的可行性和经济性。 相似文献

针对航运企业的重组与全球扩张引起的竞争问题,提出了竞争环境下的轴-辐式集装箱海运网络设计模型。模型采用基于路径的变量作为决策变量,利用离散函数来表示航运企业与航运联盟的竞争可吸引的流量(或客户),目的在于通过设计混合轴-辐式集装箱海运网络,实现以更低的服务成本和更短的服务时间最大化可吸引的流量,建立了枢纽港口数量约束、航线连接约束、航线中转约束、流量竞争约束等,运用多点交叉遗传算法进行求解,最后结合亚欧航线的集装箱海运市场进行实例分析,对考虑客户需求多样性与航运联盟对策下的轴-辐式集装箱海运网络进行设计,并验证了算法的计算效果。 相似文献

Dynamic pricing and revenue management process in Internet retailing under uncertainty: An integrated real options approach 总被引:1,自引:0,他引:1
Competition and demand volatility often cause modern enterprises to be confronted by uncertain environments. When a firm manages revenue in such competitive and risky environments, the optimization of pricing and capacity allocation, subject to a fixed time and capacity, becomes a complicated problem. Many previous papers concerning revenue management (RM) and pricing require that the firm possesses the ability to know the demand curve (or demand distribution) and set prices on it to maximize profits. However, this assumption may not be the case in some industries. Therefore, this paper focuses on the dynamic lead indicators rather than assumptive lag indicators to establish a concise and flexible decision model for practical use. This paper provides an integrated real options (IRO) approach with analytic hierarchy process (AHP) for the auction RM problem under competitive/dynamic pricing and revenue uncertainty in Internet retailing. A numerical example is also presented to illustrate that the IRO approach can generate better decisions than the naı¨ve (or risk unawareness) approach in revenue quality of safety and profitability. The new perspective and approach proposed by this paper can be extended to other RM fields whenever both profitability and risk are critical to decision making. 相似文献

We study the problem of combined pricing, resource allocation, and overbooking by service providers involved in dynamic noncooperative oligopolistic competition on a network that represents the relationships of the providers to one another and to their customers when service demand is uncertain. We propose, analyze, and compute solutions for a model that is more general than other models reported in the revenue management literature to date. In particular, previous models typically consider only three or four of five key revenue management features that we have purposely built into our model: (1) pricing, (2) resource allocation, (3) dynamic competition, (4) an explicit network, and (5) uncertain demand. Illustrative realizations of the abstract problem we study are those of airline revenue management and service provision by companies facing resource constraints. Under fairly general regularity conditions, we prove existence and uniqueness of a pure strategy Nash equilibrium for dynamic oligopolistic service network competition described by our model. We also show, for an appropriate notion of regularity, that competition leads to the underpricing of network services, a finding numerically illustrated by an example of intermediate size. Our proposed algorithm can be implemented using well‐known off‐the‐shelf commercial software. 相似文献

This paper addresses the problem of optimal planning of a liner service for a barge container shipping company. Given estimated weekly demands between pairs of ports, our goal is to determine the subset of ports to be called and the amount of containers to be shipped between each pair of ports, so as to maximize the profit of the shipping company. In order to save possible leasing or storage costs of empty containers at the respective ports, our approach takes into account the repositioning of empty containers. The line has to follow the outbound–inbound principle, starting from the port at the river mouth. We propose a novel integrated approach in which the shipping company can simultaneously optimize the route (along with repositioning of empty containers), the choice of the final port, length of the turnaround time and the size of its fleet. To solve this problem, a new mixed integer programming model is proposed. On the publicly available set of benchmark instances for barge container routing, we demonstrate that this model provides very tight dual bounds and significantly outperforms the existing approaches from the literature for splittable demands.We also show how to further improve this model by projecting out arc variables for modeling the shipping of empty containers. Our numerical study indicates that the latter model improves the computing times for the challenging case of unsplittable demands. We also study the impact of the turnaround time optimization on the total profit of the company. 相似文献

基于收益管理的思想对邮轮客舱分配与定价问题进行了研究。结合邮轮运营中的个性化特点,例如消费者团体人员构成多样、较长的预售周期以及救生位和儿童看护人员的数量限制等。在不失一般性的前提下,建立了整数规划模型用以确定在预售周期内的不同预售阶段中各种客舱类型的待售数量及其价格,以达到使邮轮公司收益最大化的目的。实验分析表明,该模型在实际应用中是有效的且呈现出显著的年增长趋势,可明显提高邮轮公司的收益。此外,设计了一种基于韦伯分布的EM算法用以解决模型中涉及到的需求量的无约束估计问题。数值算例研究表明,该算法收敛速度快且无约束估计过程可靠有效。 相似文献
