Booking control focuses on the problem of deciding whether to accept or reject bookings to maximize revenue while considering limited capacity. For freight applications, computing the cost of fulfilling requests requires solving an operational decision-making problem which often corresponds to a mixed-integer linear program. We propose a two-phase learning-based approach that first learns to predict the objective of the operational problem, then leverages the prediction within reinforcement learning algorithms to compute the policies. The method is general and applies to different problems faced in practice. We show strong performance on two booking control problems in the literature: distributional logistics and airline cargo management.

预订控制的重点是决定是否接受或拒绝预订,以便在考虑有限容量的情况下实现收益最大化。对于货运应用来说,计算满足请求的成本需要解决一个运营决策问题,而这个问题通常与混合整数线性程序相对应。我们提出了一种基于两阶段学习的方法,首先学习预测运营问题的目标,然后利用强化学习算法中的预测来计算策略。该方法具有通用性,适用于实践中面临的不同问题。我们在文献中的两个预订控制问题上展示了强大的性能:配送物流和航空货运管理。

Single and small batch production is characterized by complex value-added processes and products. The transparent calculation of new offers and change requests is therefore a particular challenge. At the same time, the rising spread of product service systems (PSS) increases the complexity of costing, as additional intangible services have to be calculated precisely. In addition to the challenges posed by such precise calculation of intangible services, companies have to master another complexity driver in the form of PSS. Innovative information and communication technologies (ICT) offer new potential for effective and efficient design of the costing process for the entire life cycle. The rising availability of data along the entire product life cycle significantly increases transparency and, thanks to intelligent analysis algorithms, allows the identification of clear cause-and-effect relationships and forecasting options. The aim of the presented paper is thus to develop a model for calculation of PPS in single and small batch production that exploits the new potential of ICT.

单件和小批量生产的特点是复杂的增值工艺和产品。因此,以透明的方式计算新报价和变更要求是一项特殊挑战。同时,产品服务系统(PSS)的日益普及也增加了成本计算的复杂性,因为额外的无形服务必须精确计算。除了精确计算无形服务所带来的挑战外,企业还必须掌握以产品服务系统为形式的另一种复杂性驱动因素。创新的信息和通信技术(ICT)为有效和高效地设计整个生命周期的成本计算过程提供了新的潜力。整个产品生命周期数据的可用性不断提高,大大增加了透明度,而且由于采用了智能分析算法,还可以识别出明确的因果关系和预测方案。因此,本文的目的是利用信息和通信技术的新潜力,为单件和小批量生产开发一个 PPS 计算模型。

In the context of volatilities in the international markets in recent times, studies regarding the complexities of oil price fluctuations have focussed on analysing the special fluctuation characteristics of oil prices in different historical perspectives. This study examines the extent to which petroleum price fluctuations under the petroleum price deregulation regime impact on business cycles in Ghana. The study uses the autoregressive distributed lag (ARDL) model with a quarterly data spanning from the first quarter of 2005 to the fourth quarter of 2022. Our empirical results show that price stability impacts positively on economic growth, both in the short and the long run, while foreign direct investment also has a positive effect on economic growth in the short run. Again, we observe that increases in inflation rate and government petroleum revenue negatively affect economic growth both in the short and the long run. To the best of the authors’ belief and knowledge, the observations and recommendations made are consistent with theory and empirical studies and contribute immensely to the discussions about price asymmetry and business cycles. It also offers a nuanced perspective on how policy makers can enact policies that ensure efficient and effective deregulation and price stability.

在近期国际市场波动的背景下,有关石油价格波动复杂性的研究侧重于从不同的历史角度分析石油价格的特殊波动特征。本研究探讨了石油价格放松管制制度下的石油价格波动对加纳商业周期的影响程度。研究采用自回归分布滞后(ARDL)模型,使用 2005 年第一季度至 2022 年第四季度的季度数据。我们的实证结果表明,无论从短期还是长期来看,价格稳定都会对经济增长产生积极影响,而外国直接投资在短期内也会对经济增长产生积极影响。同样,我们发现通货膨胀率和政府石油收入的增加对经济增长在短期和长期都有负面影响。就作者的观点和知识而言,所提出的意见和建议与理论和实证研究是一致的,对有关价格不对称和商业周期的讨论做出了巨大贡献。它还提供了一个细致入微的视角,让我们了解政策制定者如何制定政策,确保有效率和有成效地放松管制和稳定物价。

Optimal pricing of subscription services in the restaurant industry 餐饮业订阅服务的最优定价
IF 1.6 Q3 BUSINESS, FINANCE Pub Date : 2024-02-13 DOI: 10.1057/s41272-023-00470-6

Abstract

Currently, the hospitality industry is experiencing an increase in the adoption of subscription-based business models among restaurants. Pricing is a critical factor to consider when deploying the subscription models. However, only a few studies in the literature talk of pricing the new subscriptions and even in these studies no algorithm is given for setting the prices. Consequently, this study aims to derive an optimal pricing strategy for subscription services in the restaurant industry through a two-step implementable framework. In the first step, we try to understand the preferences of the consumers and accordingly curate different subscription packages for them. In the second step, we propose a linear programming-based optimization model to price these packages in an optimal manner. The linear programming model is solved by CPLEX 12.7 solver software. Finally, the authors discuss the theoretical and managerial implications of their findings.

摘要 目前,餐饮业越来越多地采用订阅式商业模式。在部署订阅模式时,定价是一个需要考虑的关键因素。然而,文献中只有少数研究谈到了新订阅模式的定价问题,即使在这些研究中也没有给出定价算法。因此,本研究旨在通过一个分两步实施的框架,推导出餐饮业订阅服务的最优定价策略。第一步,我们试图了解消费者的偏好,并据此为他们策划不同的订阅套餐。第二步,我们提出一个基于线性规划的优化模型,以最优方式为这些套餐定价。线性规划模型由 CPLEX 12.7 求解软件求解。最后,作者讨论了研究结果的理论和管理意义。

This article aims to identify the measures to overcome the COVID-19 crisis proposed by revenue managers during the lockdown period. The comparison of such measures to others against previous crises and their development afterwards is valuable to future decision-making processes in the hospitality industry. A survey of 322 professionals linked to revenue management was undertaken. The holistic and innovative point of view, integrating RM implementation, operations, marketing, and communication following the Flywheel Model, led us to revenue managers’ viewpoints about the measures to overcome the lockdown phase of the COVID-19 crisis. It is, therefore, necessary to integrate them to improve the understanding of hospitality crisis management.

本文旨在确定收益经理在封锁期间提出的克服 COVID-19 危机的措施。将这些措施与以往危机中的其他措施进行比较,以及它们在危机后的发展情况,对酒店业未来的决策过程很有价值。对 322 名与收益管理相关的专业人员进行了调查。从整体和创新的角度出发,按照飞轮模型,将 RM 的实施、运营、营销和沟通整合在一起,我们得出了收益管理者对克服 COVID-19 危机锁定阶段的措施的看法。因此,有必要将它们整合起来,以提高对酒店危机管理的理解。

Price optimization for manufacturers in a competitive retail market: imported products and online crowdfunding option 竞争激烈的零售市场中制造商的价格优化:进口产品和在线众筹选择
IF 1.6 Q3 BUSINESS, FINANCE Pub Date : 2024-02-03 DOI: 10.1057/s41272-023-00471-5

Abstract

This study explores how manufacturers in the competitive supply chain can set prices and secure funding effectively. We use game theory to look at how competition between domestic and foreign manufacturers affects pricing decisions. Our research investigates how a domestic manufacturer can improve its market share by addressing financial challenges through modern financing methods. In this scenario, a domestic manufacturer competes with a foreign one to attract a retailer’s market share and profits. The retailer decides what products to buy and how to price them based on bid prices and demand. We also consider that the domestic manufacturer will use online crowdfunding platforms to tackle its financial problem. Hence, our study sets up a supply chain where competition revolves around both operational and financial decisions. Mathematical models are developed to analyze how costs, finances, market potential, and price sensitivity impact various parts of the supply chain. The results reveal that decisions made on the crowdfunding platform significantly influence other supply chain decisions. Manufacturers and retailers need to pay attention to the financial decisions made on this platform to maximize profits. Also, domestic and foreign manufacturers should consider customer preferences for their products when setting prices. Finally, the results demonstrate that a domestic manufacturer can gain a competitive edge in the retail market by carefully considering both product pricing and financial decisions, including those made on the lending platform.

摘要 本研究探讨了在竞争激烈的供应链中,制造商如何有效地制定价格和获得资金。我们运用博弈论来研究国内外制造商之间的竞争如何影响定价决策。我们的研究探讨了国内制造商如何通过现代融资方法应对财务挑战,从而提高市场份额。在这种情况下,国内制造商与国外制造商竞争,以吸引零售商的市场份额和利润。零售商根据投标价格和需求决定购买什么产品以及如何定价。我们还考虑到,国内制造商将利用在线众筹平台来解决资金问题。因此,我们的研究设定了一个供应链,其中的竞争围绕着运营和财务决策展开。我们建立了数学模型来分析成本、财务、市场潜力和价格敏感性如何影响供应链的各个环节。研究结果表明,众筹平台上的决策会极大地影响其他供应链决策。制造商和零售商需要关注在该平台上做出的财务决策,以实现利润最大化。此外,国内外制造商在制定价格时应考虑客户对产品的偏好。最后,研究结果表明,国内制造商可以通过仔细考虑产品定价和财务决策,包括在借贷平台上做出的决策,在零售市场上获得竞争优势。

Traditional revenue management relies on long and stable historical data and predictable demand patterns. However, meeting those requirements is not always possible. Many industries face demand volatility on an ongoing basis, an example would be air cargo which has much shorter booking horizon with highly variable batch arrivals. Even for passenger airlines where revenue management (RM) is well-established, reacting to external shocks is a well-known challenge that requires user monitoring and manual intervention. Moreover, traditional RM comes with strict data requirements including historical bookings (or transactions) and pricing (or availability) even in the absence of any bookings, spanning multiple years. For companies that have not established a practice in RM, that type of extensive data is usually not available. We present a data-driven approach to RM which eliminates the need for demand forecasting and optimization techniques. We develop a methodology to generate bid prices using historical booking data only. Our approach is an ex-post greedy heuristic to estimate proxies for marginal opportunity costs as a function of remaining capacity and time-to-departure solely based on historical booking data. We utilize a neural network algorithm to project bid price estimations into the future. We conduct an extensive simulation study where we measure our methodology’s performance compared to that of an optimally generated bid price using dynamic programming (DP) and compare results in terms of both revenue and load factor. We also extend our simulations to measure performance of both data-driven and DP generated bid prices under the presence of demand misspecification. Our results show that our data-driven methodology stays near a theoretical optimum (< 1% revenue gap) for a wide-range of settings, whereas DP deviates more significantly from the optimal as the magnitude of misspecification is increased. This highlights the robustness of our data-driven approach.

传统的收益管理依赖于长期稳定的历史数据和可预测的需求模式。然而,满足这些要求并不总是可能的。许多行业都面临着持续的需求波动,例如,航空货运的预订期更短,批次到达量变化很大。即使是收益管理(RM)成熟的客运航空公司,对外部冲击做出反应也是一个众所周知的挑战,需要用户监控和人工干预。此外,传统的收益管理有严格的数据要求,包括历史预订量(或交易量)和定价(或可用性),即使在没有任何预订的情况下,也要跨越多年。对于尚未建立预订管理实践的公司来说,通常无法获得此类大量数据。我们提出了一种数据驱动的 RM 方法,无需需求预测和优化技术。我们开发了一种仅使用历史预订数据生成投标价格的方法。我们的方法是一种事后贪婪启发式方法,仅根据历史预订数据估算边际机会成本的替代值,作为剩余运力和出发时间的函数。我们利用神经网络算法来预测未来的投标价格。我们进行了广泛的模拟研究,测量了我们的方法与使用动态编程(DP)优化生成的投标价格相比的性能,并比较了收入和负载率方面的结果。我们还对模拟进行了扩展,以衡量数据驱动和 DP 生成的投标价格在需求不规范情况下的性能。我们的结果表明,我们的数据驱动方法在各种设置下都能保持在理论最优值(1% 的收入差距)附近,而 DP 则会随着错配幅度的增加而明显偏离最优值。这凸显了我们数据驱动方法的稳健性。

To investigate the demand for 5G in Germany, we applied the Van Westendorp Method (VWM) to measure willingness to pay (WTP) and price sensitivity (N = 504). The results show that more than half already own a 5G smartphone and these customers are less price sensitive. The accepted price range for the monthly 5G surcharge ranges between 10.00 and 15.40 Euros. Two thirds want more transparency in 5G pricing, while price is the most crucial factor (4.2/5.0), followed by data volume (4.1/5.0) and network operator/coverage (4.0/5.0). The results are particularly interesting for providers as the target group for 5G is quite diverse.

为了调查德国对 5G 的需求,我们采用 Van Westendorp 方法(VWM)来衡量支付意愿(WTP)和价格敏感性(N = 504)。结果显示,一半以上的用户已经拥有 5G 智能手机,这些用户对价格的敏感度较低。每月 5G 附加费的接受价格范围在 10.00 至 15.40 欧元之间。三分之二的用户希望 5G 价格更加透明,而价格是最关键的因素(4.2/5.0),其次是数据量(4.1/5.0)和网络运营商/覆盖范围(4.0/5.0)。由于 5G 的目标群体相当多样化,因此这些结果对提供商来说尤为重要。

The goal of this research is to determine whether a local brick-and-mortar (B&M) business should implement an online-to-offline (O2O) strategy, as well as the conditions under which each mode is most effective. This research examines how an O2O platform and a B&M store's (like restaurants) decision-making processes interact in a two-echelon supply chain (SC). This research employs numerical experiments and a mathematical approach to address research issues with an online food ordering service "Snappfood" that delivers from over 1,500 eateries. We first look at five case studies in which the retail price of Snappfood is determined in both a normal situation (without a marketing mechanism) and one in which the store invests in local advertising to boost demand in the self-building channel. A growth in SC profits is predicted by numerical experiments conducted under this model. The findings of decentralized decision-making reveal that in self-building mode, the store decides on both retail channels and the level of local advertising investment. In turn, the O2O platform recommended a payment delay contract as a fixed operating method for working with B&M stores. This is one of the first studies to investigate at the online sales of a local B&M store, which has the unique characteristic of offering home delivery. Second, we suggest and evaluate that a B&M store can use either the self-building technique or implementing an O2O platform for online selling.

本研究的目标是确定本地实体(B&M)企业是否应该实施线上到线下(O2O)战略,以及在何种条件下每种模式最有效。本研究探讨了 O2O 平台与 B&M 商店(如餐馆)的决策过程如何在双螺旋供应链(SC)中相互作用。本研究采用数字实验和数学方法,通过在线订餐服务 "Snappfood "来解决研究问题。我们首先研究了五个案例,在这五个案例中,Snappfood 的零售价格是在正常情况下(没有营销机制)和商店投资本地广告以促进自建渠道需求的情况下确定的。在此模型下进行的数字实验预测了 Snappfood 利润的增长。分散决策的研究结果表明,在自建模式下,商店决定零售渠道和本地广告投资水平。而 O2O 平台则建议采用延迟付款合同作为与 B&M 门店合作的固定运营方式。这是首次对本地 B&M 门店的在线销售情况进行调查的研究之一,该门店具有提供送货上门服务的独特特点。其次,我们建议并评估 B&M 商店可以使用自建技术或实施 O2O 平台进行在线销售。

In this paper, we analyze the dynamic-pricing decisions of differentiated products for retailers operating in a competitive environment, for a finite-time horizon, limited initial inventory, and in the presence of the reference effect. Customers learn from the past prices of retailers and form their estimate of sales prices, called the reference price effect, and use it to make a decision on choosing a retailer to make a purchase. The demand is uncertain, and the customer choice behavior is modeled based on a Multinomial Logit model, modified to incorporate the reference effect. The complexity of the problem increases under conditions of competition and demand uncertainty and cannot be analyzed using conventional methods. Therefore, we have used a neural network-based algorithm called Revenue-Based Neural Network (RBNN) to dynamically calculate the competitive price in order to increase the retailer’s revenue. We have analyzed the effect of competition and the performance of RBNN algorithm under two scenarios: a monopolistic situation in which a retailer uses the RBNN policy to maximize its revenue, and a duopolistic situation in which one retailer uses the RBNN strategy and the other uses an adaptive policy called Derivative Following (DF). The results of the experiments show that the pricing policy under duopolistic conditions highly affects the income of retailers in the presence of reference price. The RBNN policy outperforms the DF policy due to the learning process on the customers’ reference price. By charging higher prices in the RBNN strategy, the seller trades off the current revenue with the long-term revenue resulting from formation of higher levels of the reference price in customers’ minds and earns more revenue than its competitor overall.

在本文中,我们分析了在有限时间跨度、有限初始库存和存在参考效应的竞争环境下,零售商对差异化产品的动态定价决策。顾客从零售商过去的价格中学习,形成他们对销售价格的估计,称为参考价格效应,并以此来决定选择哪家零售商进行购买。需求是不确定的,客户选择行为的模型是基于多叉 Logit 模型,并结合参考效应进行了修改。在竞争和需求不确定的条件下,问题的复杂性增加,无法用传统方法进行分析。因此,我们使用了一种基于神经网络的算法,即基于收入的神经网络(RBNN),来动态计算竞争价格,以增加零售商的收入。我们分析了两种情况下竞争的影响和 RBNN 算法的性能:一种是垄断情况,即零售商使用 RBNN 策略使其收入最大化;另一种是双头垄断情况,即一家零售商使用 RBNN 策略,另一家零售商使用名为 "衍生跟踪"(DF)的自适应策略。实验结果表明,在有参考价格的情况下,双头垄断条件下的定价政策对零售商的收入影响很大。由于对客户参考价格的学习过程,RBNN 政策优于 DF 政策。通过在 RBNN 策略中收取更高的价格,卖方将当前收入与在客户心目中形成更高水平的参考价格所带来的长期收入进行了权衡,并在总体上比其竞争对手获得了更多的收入。
