In the constantly evolving transportation and mobility industry, objective and reliable decision‐support systems (DSS) are crucial for addressing complex issues such as transit planning, mode selection, and policy formulation. This paper presents multiactor multicriteria analysis plus agent‐based modeling (MAMCABM), a novel framework that combines multiactor multicriteria analysis (MAMCA) and agent‐based modeling (ABM) to provide a comprehensive DSS. MAMCA excels in facilitating stakeholder‐centric evaluations, while ABM, enhanced by data analytics, adeptly models intricate, interactive systems. The combination of MAMCA and ABM enhances adaptability and precision in decision making. This integration utilizes data analytics and optimization algorithms to provide solutions that consider multifaceted criteria and diverse stakeholder perspectives in dynamic and uncertain contexts. The study outlines the mathematical underpinnings of MAMCABM and offers a practical guide for its implementation. The framework's efficacy is demonstrated through an empirical investigation that addresses mobility challenges in the Brussels Capital Region of Belgium. Compared to the previous study, this approach leverages simulated quantitative data alongside qualitative judgments from stakeholders. The integration of a consensus‐reaching algorithm further enhances the robustness of outcomes and effectively addresses uncertainties.
在不断发展的交通和移动行业中,客观可靠的决策支持系统(DSS)对于解决公交规划、模式选择和政策制定等复杂问题至关重要。本文介绍了多部门多标准分析加基于代理的建模(MAMCABM),这是一种结合了多部门多标准分析(MAMCA)和基于代理的建模(ABM)的新型框架,可提供全面的 DSS。MAMCA 在促进以利益相关者为中心的评估方面表现出色,而通过数据分析增强的 ABM 则能对错综复杂的交互式系统进行出色的建模。MAMCA 和 ABM 的结合增强了决策的适应性和精确性。这种结合利用了数据分析和优化算法,在动态和不确定的环境中提供考虑多方面标准和不同利益相关者观点的解决方案。本研究概述了 MAMCABM 的数学基础,并为其实施提供了实用指南。通过对比利时布鲁塞尔首都地区交通挑战的实证调查,证明了该框架的有效性。与之前的研究相比,该方法利用了模拟定量数据和利益相关者的定性判断。整合达成共识的算法进一步增强了结果的稳健性,并有效解决了不确定性问题。

This study examines how smart food‐sharing platforms (SFSP) can help reduce food waste and suggests a method for using smart contracts to share extra food among different partners effectively. For smart contracts to work automatically and prevent food wastage, artificial intelligence systems can recognize how smart clauses should be executed. This will involve analyzing several factors like the selling price, expiration dates, offers from other partners, transport costs, wholesale price, shelf life, donation rates, and demand rates. The findings indicate that adopting an SFSP is an efficient solution for preemptively adopting redistribution strategies and improving social outcomes through donations as well as achieving positive environmental outcomes through reduced waste. However, we also identify cases in which reducing food waste to achieve social sustainability may negatively impact economic performance.
本研究探讨了智能食物共享平台(SFSP)如何帮助减少食物浪费,并提出了一种利用智能合约在不同合作伙伴之间有效共享多余食物的方法。为使智能合约自动运行并防止食物浪费,人工智能系统可以识别应如何执行智能条款。这将涉及分析几个因素,如销售价格、过期日期、其他合作伙伴的报价、运输成本、批发价格、保质期、捐赠率和需求率。研究结果表明,采用 SFSP 是一种有效的解决方案,可以预先采取再分配策略,通过捐赠改善社会成果,并通过减少浪费实现积极的环境成果。不过,我们也发现,在一些情况下,为实现社会可持续性而减少食物浪费可能会对经济绩效产生负面影响。

American options are one of the most traded instruments in the financial markets. However, pricing them is challenging because of the early exercise possibility. We propose a robust pricing method based on nonlinear regression over a representative set of “exact” pricing instances obtained via a binomial lattice. Our “power approximation” approach is inspired from the literature on the well‐known periodic review inventory system. Our objective is to develop a closed‐form approximation for pricing American options that performs well on accuracy, computational efficiency (speed), and simplicity. Our results include developing a large set of “exact” American option premiums and critical stock price (indicating when to exercise the option) over a carefully designed grid with parameter values, which are common in practice. In addition, we compile the literature for existing American option pricing approximations and identify suitable ones. These approximations serve two purposes: (i) providing a starting point for our approximations and (ii) developing a benchmark for our work. We develop two closed‐form approximations for the critical stock price, and premium of an American put option, which perform very well with a median error below 0.45% for both.
美式期权是金融市场上交易量最大的工具之一。然而,由于美式期权可能提前行权,因此其定价具有挑战性。我们提出了一种稳健的定价方法,该方法基于对通过二叉网格获得的一组有代表性的 "精确 "定价实例的非线性回归。我们的 "幂近似 "方法受到了著名的定期审查库存系统文献的启发。我们的目标是为美式期权定价开发一种闭式近似方法,这种方法在准确性、计算效率(速度)和简便性方面都表现出色。我们的成果包括在精心设计的网格上,利用实践中常见的参数值,开发出一大套 "精确 "的美式期权权利金和临界股票价格(表明何时行使期权)。此外,我们还汇编了现有美式期权定价近似值的文献,并找出了合适的近似值。这些近似方法有两个目的:(i) 为我们的近似方法提供起点;(ii) 为我们的工作制定基准。我们为美式看跌期权的临界股价和期权金开发了两个闭式近似值,这两个近似值的表现都很好,中位误差都低于 0.45%。

Hybrid financing in a dual‐channel supply chain with asymmetric demand information 需求信息不对称的双渠道供应链中的混合融资

This study delves into the interaction between hybrid financing and asymmetric demand information within a dual‐channel supply chain. In this setup, the supplier directly sells to customers and also through a capital‐constrained retailer. We investigate a unique financing approach involving a blend of bank loans and supplier equity investment to support the retailer's operational (procurement and marketing) activities. Analyzing the equilibrium strategies under both symmetric and asymmetric information settings yields intriguing insights. In the case of symmetric information, we find that the retailer's equilibrium order quantity decreases with the potential market size under hybrid financing, contrary to traditional notions. When asymmetric information is present, a higher acceptance of supplier equity investment by the retailer tends to lead to order quantity distortion downward, increasing signaling costs. Furthermore, a greater proportion of supplier equity investment prompts the retailer to order more products, ultimately boosting profits for both the retailer and supplier. This suggests that supplier equity investment can enhance supply chain efficiency and alleviate the double marginalization effect.
本研究探讨了双渠道供应链中混合融资与需求信息不对称之间的相互作用。在这种情况下,供应商直接向客户销售,同时也通过资本受限的零售商销售。我们研究了一种独特的融资方法,其中涉及银行贷款和供应商股权投资的混合,以支持零售商的运营(采购和营销)活动。通过分析对称和非对称信息环境下的均衡策略,我们发现了一些耐人寻味的见解。在信息对称的情况下,我们发现在混合融资条件下,零售商的均衡订货量会随着潜在市场规模的扩大而减少,这与传统观念相反。当信息不对称时,零售商对供应商股权投资的接受度越高,往往会导致订货量向下扭曲,从而增加信号传递成本。此外,更大比例的供应商股权投资会促使零售商订购更多产品,最终提高零售商和供应商的利润。这表明,供应商股权投资可以提高供应链效率,缓解双重边缘化效应。

Online review sites play a crucial role in shaping consumer purchasing decisions, making the analysis of customer feedback essential for businesses. Given the complexity of these reviews, often including both quantitative and qualitative data, advanced analytical frameworks are necessary. To this end, this paper introduces an integrated framework for customer feedback analysis, combining aspect‐based sentiment analysis, multicriteria decision‐making, and a fuzzy rule‐based approach. The proposed system effectively processes both textual and numerical data from online reviews, enabling the extraction of actionable insights. To demonstrate its practical utility, we apply it to a real‐world dataset from a major European airline. The results illustrate the framework's effectiveness in identifying key factors influencing customer satisfaction and pinpointing areas needing improvement. Additionally, data‐driven recommendations are provided to support business decision‐making and enable the customization of products and services to better meet customer expectations.

We develop a method for modelling multi‐stage production using stochastic frontier analysis. This approach is suitable for the analysis of costs or output where intermediate outputs become inputs into a subsequent stage of the production process, either within an organisation or in the form of a supply chain. Our focus is on higher education institutions in England, and the purpose is to assess the performance of our novel methods using Markov Chain Monte Carlo methods. Without taking into full account of the complexity of the ‘network’, key decisions cannot be made regarding intake quality, student/staff ratios, per‐student spending or academic reputation (the last of which involves costly decisions in terms of academic openings and the profile of candidates desired for any given university).
我们开发了一种利用随机前沿分析建立多阶段生产模型的方法。这种方法适用于分析成本或产出,其中中间产出成为生产流程后续阶段的投入,无论是在组织内部还是以供应链的形式。我们的重点是英格兰的高等教育机构,目的是利用马尔可夫链蒙特卡罗方法评估我们的新方法的性能。如果不充分考虑 "网络 "的复杂性,就无法做出有关招生质量、学生/教职员工比例、学生人均支出或学术声誉的关键决策(最后一项决策涉及学术开放和任何特定大学所需的候选人情况等方面的代价高昂的决策)。

Oil‐to‐electricity retrofitting and deployment of rubber‐tyred gantry cranes considering low‐carbon policies 考虑到低碳政策,对橡胶轮胎龙门起重机进行油改电改造和部署

To address the high‐carbon emissions from port equipment, one of the most effective measures is to replace diesel‐powered rubber‐tyred gantry cranes (RTGs) with electric‐powered alternatives. However, the oil‐to‐electricity retrofitting for diesel‐driven RTGs may negatively impact port operation efficiency. Moreover, port enterprises typically do not initiate the retrofitting without the low‐carbon policies. Therefore, this study focuses on the retrofitting of RTGs in combination with their deployment under the carbon emissions trading (CET) and government subsidy policies. An integer programming model is developed to help port enterprises determine the multistage planning of RTGs' retrofitting and deployment. Based on the block‐diagonal structure of the proposed model, a column generation method employing Dantzig–Wolfe decomposition is developed. The optimal integer solution of the model is then further refined using a branch‐and‐price approach. The Shanghai Yangshan Deep Water Port is used for numerical experiments. Numerical results demonstrate that the implementation of CET and government subsidy policies can reduce approximately 17,630 tons of carbon emissions and $8,751,861 operating costs in container terminal yard. Meanwhile, increasing government subsidies and carbon trading prices, and reducing free carbon emission quotas can encourage port enterprises to reduce more emissions.
为解决港口设备的高碳排放问题,最有效的措施之一是用电力驱动的设备取代柴油驱动的橡胶轮胎龙门起重机(RTG)。然而,对柴油驱动的橡胶轮胎门式起重机进行油改电改造可能会对港口运营效率产生负面影响。此外,在没有低碳政策的情况下,港口企业通常不会主动进行改造。因此,本研究重点关注在碳排放交易(CET)和政府补贴政策下,结合 RTG 的部署对 RTG 进行改造。本文建立了一个整数编程模型,以帮助港口企业确定 RTG 改造和部署的多阶段规划。根据所提模型的对角分块结构,开发了一种采用 Dantzig-Wolfe 分解的列生成方法。然后采用分支-价格法进一步完善模型的最优整数解。数值实验以上海洋山深水港为对象。数值结果表明,实施 CET 和政府补贴政策可减少集装箱码头堆场约 17,630 吨的碳排放量和 8,751,861 美元的运营成本。同时,提高政府补贴和碳交易价格,减少免费碳排放配额,可以鼓励港口企业减少更多排放。

Planning in management: identifying alternative ways of improving performance toward best practices 管理规划:确定提高绩效的其他方法,实现最佳实践

Planning is an important part of the management of organizations, which deals with the setting of targets that guide the actions needed to improve performance. Decision making is at the essence of planning, as it involves the identification of alternative directions for improvement and the selection of a future course of action. Decision makers (DMs) appreciate information on different ways of improving performance toward best practices, so they can make a choice of the plan that is more closely aligned with management in an ex post evaluation of possibilities. This paper responds to the need of providing DMs with a few (manageable) alternatives when planning improvements. The proposed approach is developed within the framework of data envelopment analysis (DEA). Although DEA has been used for planning, there is a gap in the literature in the sense that we can find only a few papers that have the explicit aim of identifying alternatives. In order to deal with this issue, we explore the whole DEA strong efficient frontier through all of its maximal efficient faces, which allows us to handle targets determined by a broad range of reference sets, and then use location theory tools, namely a p‐median problem, for the selection of p representatives that define alternative directions for improvement. Eventually, DMs are provided with a decision‐support tool for planning improvements by learning from the best practices of others, without requiring prior information on preferences.
规划是组织管理的一个重要组成部分,它涉及设定目标,以指导提高绩效所需的行动。决策是规划的精髓所在,因为它涉及确定其他改进方向和选择未来的行动方案。决策制定者(DMs)需要了解有关提高绩效的最佳做法的各种方法的信息,以便在事后评估各种可能性时,选择与管理层更密切相关的计划。本文旨在满足管理者在制定改进计划时提供一些(可管理的)备选方案的需求。本文提出的方法是在数据包络分析(DEA)框架内开发的。尽管数据包络分析已被用于规划,但文献中仍存在空白,因为我们只能找到几篇明确以确定替代方案为目标的论文。为了解决这个问题,我们探索了整个 DEA 强有效边界的所有最大有效面,这使我们能够处理由广泛的参考集决定的目标,然后使用位置理论工具,即 p 中值问题,来选择 p 个代表,这些代表定义了可供选择的改进方向。最终,我们为管理者提供了一个决策支持工具,让他们通过学习他人的最佳实践来规划改进工作,而无需事先了解偏好信息。

Eventually, DMs are provided with a decision‐support tool for planning improvements by learning from the best practices of others, without requiring prior information on preferences.","PeriodicalId":49176,"journal":{"name":"International Transactions in Operational Research","volume":"74 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142217004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Decentralized energy systems can be an alternative to stabilizing the power system in a rapidly changing power market environment. In this regard, it is very important to level the significant gap between electricity loads and power generation, which is caused by expanding renewable energy resources. This study investigates an electricity control strategy to encourage forming a microgrid and to level the load profile that the microgrid optimizes based on its individual objective. To address the problems encountered by two players at different decision levels, this study introduces a bilevel optimization model that considers two players’ objectives. In the proposed model, the first player is called the grid system operator, and the decisions of the player are subsidy rates for distributed generators and an energy storage system. The second player is called the community microgrid, and the major decisions of the player are the configuration and operation of the microgrid. To solve the problem, an efficient algorithm is developed based on Karush–Kuhn–Tucker (KKT) conditions and a decomposition approach. Numerical experiments show that the peak load can be reduced by setting an adequate subsidy rate.
在瞬息万变的电力市场环境中,分散式能源系统可以成为稳定电力系统的替代方案。在这方面,拉平电力负荷与发电量之间的巨大差距非常重要,这种差距是由可再生能源的不断扩大造成的。本研究探讨了一种电力控制策略,以鼓励组建微电网,并根据微电网的个体目标来平抑微电网优化的负荷曲线。为了解决两个参与者在不同决策层面遇到的问题,本研究引入了一个考虑两个参与者目标的双层优化模型。在提议的模型中,第一个参与者被称为电网系统运营商,其决策是对分布式发电机和储能系统的补贴率。第二个参与者称为社区微电网,其主要决策是微电网的配置和运行。为了解决这个问题,我们开发了一种基于卡氏-库恩-塔克(KKT)条件和分解方法的高效算法。数值实验表明,通过设定适当的补贴率,可以降低峰值负荷。

The logistics market represents a fundamental segment for the circulation of goods and greater economic activity. Logistics startups have been gaining great importance, being potential substitutes for traditional carriers. Given this context, there is a huge need for large carriers to develop digital and sustainable solutions, and especially to look at inorganic strategies such as mergers and acquisitions. However, the process by which carriers may acquire logistics startups is quite complex. This study sought to solve the problem of ranking logistics startups with the potential to be acquired by the carrier in a Brazilian company through a multi‐criteria approach. The Flexible and Interactive Tradeoff (FITradeoff) method was used to solve the case and a ranking of the startups was obtained. The whole process was quick and simple, so this study contributes to proposing a useful model for logistics problems, and demonstrates the practicality of how to solve them using FITradeoff.
物流市场是商品流通和扩大经济活动的重要环节。物流初创企业作为传统承运商的潜在替代者,其重要性日益凸显。在这种情况下,大型承运商亟需开发数字化和可持续的解决方案,特别是要考虑并购等无机战略。然而,承运商收购物流初创企业的过程相当复杂。本研究试图通过多标准方法,解决巴西一家公司对有可能被运营商收购的物流初创企业进行排序的问题。研究采用了灵活互动权衡法(FITradeoff)来解决这个问题,并得出了初创企业的排名。整个过程快速而简单,因此本研究有助于为物流问题提出一个有用的模型,并展示了如何使用 FITradeoff 解决这些问题的实用性。
