Demand forecasting lies at the heart of any revenue management system. It aims to estimate the quantity of a product or service that will be purchased in the future. In this paper, we perform railway demand forecasting for a major European railroad company by taking various contributing parameters into account. To have multipurpose results, the current problem is explored in two different aggregation levels. At the high level, the problem is defined as prediction of the total number of bookings for all trains departing on a specific departure date and within a certain time range. Moreover, in a more disaggregated level, the prediction models aim to compute the total number of bookings within each booking period for all trains leaving in a specific time range of a certain departure date. Using state-of-the-art machine learning methods and various heuristic feature construction techniques, remarkable results with high forecast accuracy and reasonable computational complexity are achieved in both aggregation levels. This paper aims to contribute to the application of ML techniques in RM by introducing new heuristic feature engineering techniques, exploring the importance of accurate clustering, and implementing state-of-the-art machine learning methods in the context of railway industry.
需求预测是任何收入管理系统的核心。它旨在估计未来将购买的产品或服务的数量。在本文中,我们通过考虑各种贡献参数来对欧洲一家主要铁路公司的铁路需求进行预测。为了获得多用途的结果,在两个不同的聚合级别上探讨了当前的问题。在高层,该问题被定义为预测在特定发车日期和特定时间范围内发车的所有列车的预订总数。此外,在更细分的层面上,预测模型旨在计算在某个出发日期的特定时间范围内出发的所有列车在每个预订期内的预订总数。使用最先进的机器学习方法和各种启发式特征构建技术,在两个聚合级别上都取得了预测精度高、计算复杂度合理的显著结果。本文旨在通过引入新的启发式特征工程技术,探索精确聚类的重要性,并在铁路行业中实现最先进的机器学习方法,为ML技术在RM中的应用做出贡献。

Indonesian mutual funds: performance determinants and interaction of macroeconomic factors 印度尼西亚共同基金:业绩决定因素和宏观经济因素的相互作用

We examine the determinants of fund returns of equity, fixed income, mixed, and money market mutual funds in Indonesia. Our empirical findings suggest that previous fund performances are significant determinants of current fund performances. On the other hand, fund age, management fee, and management period of the investment manager are not significant determinants of fund performances. Fund size is a significant determinant of fund performances only for equity funds. Furthermore, introducing the interest rate as a moderator variable weakens the effect of fund size on fund returns only for equity funds and it weakens the effect of the exchange rate on fund performances for equity and money market funds. For fixed income and mixed funds, the moderator variable does not change the effects of fund size and the exchange rate on fund performances. Overall, the robustness tests using three partitions of fund performances, namely bottom 20%, middle 60%, and top 20%, confirm our main findings. An interesting result is that returns of middle performers of fixed income funds are more sensitive to the changes of determinants than those of bottom and top performers.
我们研究了印尼股票基金、固定收益基金、混合基金和货币市场共同基金的基金回报决定因素。我们的实证结果表明,以前的基金业绩是当前基金业绩的重要决定因素。另一方面,基金年龄、管理费用和投资管理人的管理期限并不是影响基金业绩的重要因素。基金规模是基金业绩的重要决定因素,仅限股票基金。此外,引入利率作为调节变量,削弱了基金规模对基金回报的影响(仅适用于股票型基金),也削弱了汇率对股票型基金和货币市场基金基金业绩的影响。对于固定收益型和混合型基金,调节变量不会改变基金规模和汇率对基金业绩的影响。总体而言,使用基金业绩的三个分区(即底部20%、中间60%和顶部20%)进行的稳健性测试证实了我们的主要发现。一个有趣的结果是,固定收益基金中表现中等的回报率比表现最差和最优秀的回报率对决定因素的变化更敏感。

A closed-form approximation for pricing geometric Istanbul options 几何伊斯坦布尔期权定价的封闭近似

The concept of Istanbul options were first introduced by Michel Jacques in 1997. These derivatives products are considered as an extension of the Asian options. In this paper, we propose an analytical approximation formula for a geometric Istanbul call option (GIC) under the standard Black-Scholes model. Our approximate pricing formula is obtained in closed-form using a second-order Taylor expansion. We compare our theoretical results with those of Monte Carlo simulations using the control variates method. We also carry out a comparative price study with an arithmetic Istanbul call option. Finally, we study the effects of changes in the price of the underlying asset on the value of GIC.
1997年,米歇尔•雅克(Michel Jacques)首次提出了伊斯坦布尔选项的概念。这些衍生产品被认为是亚洲期权的延伸。本文提出了标准Black-Scholes模型下几何Istanbul看涨期权(GIC)的解析近似公式。我们的近似定价公式是用二阶泰勒展开的封闭形式得到的。我们用控制变量法将理论结果与蒙特卡罗模拟结果进行了比较。我们还与算术伊斯坦布尔看涨期权进行了价格比较研究。最后,我们研究了标的资产价格变动对政府投资债券价值的影响。

Pandemics such as COVID-19 can challenge many of the very well-established strategies of revenue management The purpose of this paper is to subject the four widely used strategies of revenue management in the hotel industry into an empirical analysis for their suitability at the time of crisis The data driven approach to modelling has been adopted in this research based on the real-life data obtained from the property management system of nine of the 5-star hotels in Qatar The results indicate that four of these hypotheses are supported This revelation has been the basis for drawing implications to the finance and marketing managers of hotels to enhance customer satisfaction and maximise hotel revenue during the COVID-19 or any such pandemic The results are based on real-life data and have the foundation of well-established pricing strategies in use at the hotels Copyright © 2021 Inderscience Enterprises Ltd
