This case study provides a comprehensive decision-making scenario that takes students through all three types of analytics—descriptive, predictive, and prescriptive—to provide recommendations to a decision maker. The scenario focuses on an individual investor who is purchasing LEGO sets from retailers with the goal of selling them for a higher price on the aftermarket in a few years once they retire from shelves. Students must create visualizations to generate insights from the data and develop a regression model to identify sets that represent value investment opportunities. In the extension case they must take their estimated values and optimize the decisions of which sets to purchase to meet the decision maker’s investment goals using an integer program. Students also have the opportunity to develop soft skills in problem solving and communicating results and dealing with missing data points in a data set that is larger than standard textbook data sets but is still a manageable size for introductory students. The open-ended instructions make the case appropriate for a wide range of students from the introductory undergraduate level to the advanced graduate level. Supplemental Material: Supplemental materials are available at https://doi.org/10.1287/ited.2023.0288ca . The Teaching Note and data files are available at https://www.informs.org/Publications/Subscribe/Access-Restricted-Materials .
本案例研究提供了一个全面的决策场景,带学生通过所有三种类型的分析——描述性、预测性和规定性——向决策者提供建议。该场景聚焦于一位个人投资者,他正在从零售商那里购买乐高玩具,目标是在几年后它们从货架上退役后,在售后市场上以更高的价格出售。学生必须创建可视化,以从数据中产生见解,并开发回归模型,以确定代表价值投资机会的集合。在扩展的情况下,他们必须采用他们的估计值,并使用整数程序优化购买哪些集合的决策,以满足决策者的投资目标。学生们还有机会发展解决问题和交流结果的软技能,以及处理数据集中缺失的数据点,该数据集比标准教科书数据集大,但对于入门学生来说仍然是一个可控的规模。开放式说明适用于从入门级本科生到高级研究生的广泛学生。补充材料:补充材料可在https://doi.org/10.1287/ited.2023.0288ca。教学笔记和数据文件可在https://www.informs.org/Publications/Subscribe/Access-Restricted-Materials。

Drake Matthew J. Drake Published Online:13 Jun 2023https://doi.org/10.1287/ited.2023.0288csbGreg McCullough has conducted a thorough analysis of the more than 600 LEGO sets released in 2018 and 2019 to gain a better understanding of the characteristics of the different themes and subthemes. His overall goal is to identify the sets in which he should invest. After the sets retire, he expects to use the proceeds from selling the sets to supplement his family’s collecting passion.Although the future value of a retired LEGO set is partially dependent on the desirability of the set itself and the theme (such as Harry Potter, Minecraft, Star Wars, etc.), another major determinant of the desirability of a set as an investment is the value potential, which is defined as the difference between the price that LEGO “should” be charging for the set based on its characteristics and the actual retail price. Sets with large value potential represent outsized investment opportunities in much the same way that a value mutual fund invests in securities that are potentially undervalued based on their fundamentals.In his prior analysis, Greg developed a model that determines the price that LEGO should be charging for sets and has used it to determine the value potential for all of the sets that were released in 2019. Some sets ending up having positive value potentials, whereas others had negative value potentials. He eliminated all the sets with negative value potential from further investment consideration. He also researched the resale prices for retired LEGO sets on the secondary market and narrowed his potential investment options to sets in the following themes: City, Creator, DC Super Heroes, Friends, Harry Potter, Hidden Side, Ideas, Marvel Super Heroes, Minecraft, Ninjago, Overwatch, Speed Champions, and Star Wars. This left him with the 109 sets listed in the data file provided.Greg’s task now is to determine which specific sets he should purchase as an investment.

Intensive competition among supply chains often forces trading partners to collaborate despite their conflict of interests. Supply chain contracts and collaboration theory is well established in the academic literature to align the interests but much less conveyed to students and industry professionals for a practical impact. Although the Beer Game captures the bullwhip effect and the value of information sharing, it ignores the conflict of interests, that is, price and quantity bargaining, among the trading partners. We describe a new online teaching game, the FloraPark simulation (“the flower game” at https://flower.gamespots.net/ ), based on real-life events in the international fresh-cut flower supply chains, for students to learn supply chain collaboration via contracts in a setting of multiple supply chains competing in the same market. Students play trading partners in the flower supply chains and experiment with the push, pull, and advanced purchasing discount contracts by negotiating wholesale prices and quantities to achieve the conflicting objectives of (1) collaboration to beat other supply chains, and (2) bargaining to protect their own interests from their trading partners.

供应链之间的激烈竞争往往迫使贸易伙伴在利益冲突的情况下进行合作。供应链合同和合作理论在学术文献中已经得到了很好的确立,以协调利益,但很少传达给学生和行业专业人士以产生实际影响。虽然啤酒游戏捕捉到了牛鞭效应和信息共享的价值,但它忽略了贸易伙伴之间的利益冲突,即价格和数量的讨价还价。我们描述了一个新的在线教学游戏,FloraPark模拟(“花游戏”https://flower.gamespots.net/),基于国际鲜切花供应链中的真实事件,让学生在多个供应链在同一市场竞争的环境中通过合同学习供应链协作。学生们在鲜花供应链中扮演贸易伙伴,通过谈判批发价格和数量来尝试推、拉和高级购买折扣合同,以实现(1)合作击败其他供应链和(2)讨价还价以保护自己的利益不受贸易伙伴的影响这两个相互冲突的目标。补充材料:电子公司可在https://doi.org/10.1287/ited.2022.0035。

Which Data Sets Are Preferred by University Students in Learning Analytics Dashboards? A Situated Learning Theory Perspective 大学生在学习分析仪表板时更喜欢哪些数据集?情境学习理论视角
Q3 Social Sciences Pub Date : 2023-05-11 DOI: 10.1287/ited.2023.0289

Scholarly interests in developing personalized learning analytics dashboards (LADs) in universities have been increasing. LADs are data visualization tools for both teachers and learners that allow them to support student success and improve teaching and learning. In most LADs, however, a teacher-centric, institutional view drives their designs, treating students only as passive end-users, which results in LADs being less useful to students. To address this limitation, we used a card-sorting technique and asked 42 students at a university in Northern Ireland to construct dashboards that reflect their priorities. Using a situated theory of learning as a lens and with the help of multiple qualitative methods, we collected data on what constitutes useful dashboards. Findings suggest that situated learning data sets, such as information on how students learn by talking and listening to others in their communities, need to be integrated into LADs. Students preferred to see the inclusion of qualitative narratives, self-directed learning data and financial information (money spent versus resources utilized) in LADs. As well as raising new questions on how such LADs could be designed, this study challenges institutional overreliance on measurable digital footprints as proxies for academic success. We call for recognizing the wider social learning that happens in landscapes of practice so that LADs become more useful to students.
在大学中开发个性化学习分析仪表板(LADs)的学术兴趣一直在增加。lad是为教师和学习者提供的数据可视化工具,使他们能够支持学生的成功并改善教学和学习。然而,在大多数教学辅助课程中,以教师为中心的制度观点驱动着他们的设计,将学生仅仅视为被动的最终用户,这导致教学辅助课程对学生的用处不大。为了解决这一限制,我们使用了卡片分类技术,并要求北爱尔兰一所大学的42名学生构建反映他们优先级的仪表板。以一种情境学习理论为视角,在多种定性方法的帮助下,我们收集了构成有用仪表板的数据。研究结果表明,需要将现有的学习数据集,例如关于学生如何通过与社区中的其他人交谈和倾听来学习的信息,整合到lad中。学生们更喜欢在学习报告中看到定性叙述、自主学习数据和财务信息(花费的资金与使用的资源)。这项研究不仅提出了如何设计这样的学习进度指标的新问题,还挑战了机构过度依赖可测量的数字足迹作为学业成功的代表。我们呼吁认识到在实践中发生的更广泛的社会学习,以便lad对学生更有用。

Introducing Prescriptive and Predictive Analytics to MBA Students with Microsoft Excel 使用Microsoft Excel向MBA学生介绍规定性和预测性分析
Q3 Social Sciences Pub Date : 2023-05-04 DOI: 10.1287/ited.2023.0286

Managers are increasingly being tasked with overseeing data-driven projects that incorporate prescriptive and predictive models. Furthermore, basic knowledge of the data analytics pipeline is a fundamental requirement in many modern organizations. Given the central importance of analytics in today’s business environment, there is a growing demand for educational pedagogies that give students the opportunity to learn the fundamentals while also familiarizing them with how such tools are applied. However, a tension exists between the introduction of real-world problems that students can analyze and extract insight from and the need for prerequisite knowledge of mathematical concepts and programming languages such as Python/R. As a consequence, this paper describes an application-focused course that uses Microsoft Excel and mathematical programming to introduce MBA students with nontechnical backgrounds to tools from both prescriptive and predictive analytics. While students’ gain proficiency in managing data and creating optimization and machine learning models, they are also exposed to broader business concepts. Teaching evaluations indicate that the course has helped students further develop their practical skills in Microsoft Excel, gain an appreciation of the real-world impact of data analytics, and has introduced them to a discipline they originally believed was best suited for more technically focused professionals.
管理人员越来越多地负责监督数据驱动的项目,这些项目包含规范性和预测性模型。此外,数据分析管道的基本知识是许多现代组织的基本要求。鉴于分析学在当今商业环境中的核心重要性,对教育教学法的需求日益增长,这种教学法既能让学生有机会学习基础知识,又能让他们熟悉这些工具的应用。然而,在引入学生可以分析和从中提取见解的现实问题与对数学概念和编程语言(如Python/R)的先决知识的需求之间存在紧张关系。因此,本文描述了一门以应用为中心的课程,该课程使用Microsoft Excel和数学编程向具有非技术背景的MBA学生介绍规范性和预测性分析的工具。在学生熟练掌握管理数据、创建优化和机器学习模型的同时,他们也接触到了更广泛的商业概念。教学评估表明,这门课程帮助学生进一步发展了他们在Microsoft Excel中的实践技能,了解了数据分析对现实世界的影响,并向他们介绍了一门他们原本认为最适合更专注于技术的专业人士的学科。

Improving Mathematical Exposition of an Industrial-Scale Linear Program 改进工业规模线性规划的数学表述
Q3 Social Sciences Pub Date : 2023-04-28 DOI: 10.1287/ited.2023.0283
Gus Greivel, A. Newman, Maxwell Brown, K. Eurek
Industrial-scale models require considerable setup time; hence, once built, they are used in myriad ways to consider closely related cases. In practice, the code for these models frequently evolves without appropriate notational choices, largely as a result of the lengthy development time of, and the number of individuals contributing to, their formulation. This leads to inefficiencies and obfuscates model structures that might be leveraged to expedite solutions. In this paper, we advocate for an emerging literature on model formulation “best practices” and present the reformulation of a widely used industrial-scale linear program. The efficient mathematical expression of this linear program, used to plan capacity expansion in the energy sector, allows for greater transparency of model structures and enhanced ability to identify computational performance improvements, as well as a lucid interpretation of its solutions. This type of formulation is employed in several mathematical programming courses at our university as an example of the advantages of best practices; the model more broadly is used widely to inform policy in the U.S. energy sector.

工业规模的模型需要相当长的设置时间;因此,一旦建立起来,它们就以各种方式被用来考虑密切相关的案例。在实践中,这些模型的代码经常在没有适当的符号选择的情况下演变,这主要是由于其公式的开发时间长以及参与其公式的个人数量多。这会导致效率低下,并混淆可能用于加快解决方案的模型结构。在本文中,我们提倡一种关于模型制定的新兴文献“最佳实践”,并提出了一种广泛使用的工业规模线性规划的重新制定。该线性程序用于规划能源部门的产能扩张,其高效的数学表达式可以提高模型结构的透明度,增强识别计算性能改进的能力,并对其解决方案进行清晰的解释。这种类型的公式被用于我们大学的几个数学编程课程,作为最佳实践优势的一个例子;该模型被更广泛地用于为美国能源部门的政策提供信息。资助:这项工作得到了国家可再生能源实验室(实验室指导的研究和开发计划)的支持。

Managing the Hyflex Scheduling Activity Using Excel Dynamic Arrays 使用Excel动态数组管理Hyflex调度活动
Q3 Social Sciences Pub Date : 2023-04-21 DOI: 10.1287/ited.2023.0287
L. LeBlanc, Thomas A. Grossman, Michael R. Bartolacci
The COVID-19 pandemic has forced the rapid adoption of remote teaching modalities including “hyflex” where students attend some class sessions in person and some online. Managing the hyflex course requires faculty to quickly generate several reports and to update these reports rapidly when the authorities adjust the rules, students add/drop, or the number of course sessions is changed. The creation of these reports is tedious and error-prone, so they need to be automated. However, the nature of the task precludes traditional Excel programming approaches. We use Excel’s new “dynamic array” capabilities (which are available only in Excel 365) to automate the creation and updating of the reports needed to manage the hyflex course. We show how to program the reports, and we discuss the importance of taking an iterative approach to creating effective, error-free cell formulas. To help the reader acquire genuine access to the dynamic array functions, we provide a practical tutorial on the principles and new concepts of dynamic arrays, explain how they relate to legacy array functions, and present selected dynamic array functions including SEQUENCE, FILTER, and XLOOKUP.
2019冠状病毒病大流行迫使学校迅速采用远程教学模式,包括“hyflex”,学生可以亲自参加一些课程,也可以在线参加一些课程。管理hyflex课程需要教师快速生成多个报告,并在当局调整规则、增加/减少学生或更改课程课时数时快速更新这些报告。这些报告的创建是乏味且容易出错的,因此它们需要自动化。然而,任务的性质排除了传统的Excel编程方法。我们使用Excel的新“动态数组”功能(仅在Excel 365中可用)来自动创建和更新管理hyflex课程所需的报告。我们将展示如何编写报告,并讨论采用迭代方法创建有效、无错误的单元格公式的重要性。为了帮助读者获得对动态数组函数的真正访问,我们提供了关于动态数组的原理和新概念的实用教程,解释了它们如何与遗留数组函数相关联,并介绍了选定的动态数组函数,包括SEQUENCE、FILTER和XLOOKUP。

An OR Approach for WORdle WORD的OR方法
Q3 Social Sciences Pub Date : 2023-04-20 DOI: 10.1287/ited.2023.0285
Simran Lakhani, Mustafa Vora, Ashutosh Mahajan
Modeling exercises are designed around the popular game Wordle. These exercises can possibly be used in a computational or modeling laboratory course or in a course on modeling operations research (OR) problems. They assume some familiarity with modeling integer programs, a programming language like Python for basic text processing, and optimization software like AMPL or PYOMO. These exercises were tried in a master’s-level course on modeling OR problems. Two sessions of three hours each are ideal for the whole exercise.
建模练习是围绕流行游戏Wordle设计的。这些练习可以用于计算或建模实验室课程,也可以用于建模运筹学(or)问题的课程。他们假设对整数程序建模、用于基本文本处理的Python等编程语言以及AMPL或PYOMO等优化软件有一定的熟悉程度。这些练习在一门关于OR问题建模的硕士课程中进行了尝试。两次,每次三小时,是整个锻炼的理想选择。
