Uncertainties, such as road restrictions at shipyards and the irregular shape of blocks, pose challenges for transporter scheduling. Efficient scheduling of multiple transporters is critical to ...improving transportation efficiency. The digital twin (DT) technology offers numerous benefits, enabling interactions between the virtual and real worlds, real-time mapping, and dynamic performance evaluation. Based on DT technology, this study proposes a dynamic scheduling approach for cooperative transportation utilizing multiple transporters. The scheduling problem for multiple transporters is addressed and modeled in this study, considering factors such as block size and transporter loading. To solve this problem, a framework of DT-based multiple transporters system is established in a virtual environment. By inputting block information into this system, a solution is generated using transporter scheduling rules and interference detection methods. Experimental comparisons are conducted in this paper, exploring various scenarios with different number of tasks and the application of DT. The results demonstrate that the proposed approach effectively enhances transportation efficiency and improves ship construction efficiency. Hence, this study expands the application of DT technology in dynamic scheduling of transportation in shipyards and provides new ideas for shipbuilding company managers.
Dieser Open-Access-Sammelband zeigt, wie innovative Forschung und Lehre in der Volkswirtschaftslehre zu einer besseren Gesellschaft beitragen können. Eine Wirtschaftspolitik mit Ziel und Plan sollte ...auf rigorosem theoretischem Fundament stehen und sich auf verlässliche empirische Evidenz stützen. Damit die Forschung Wirkung entfalten kann, müssen die Forscher die neuesten Erkenntnisse in eine populäre Sprache übersetzen, damit sie einer breiten und nicht spezialisierten Öffentlichkeit zugänglich werden. Wähler und Entscheidungsträger der Politik können von den Ergebnissen der Forschung nur profitieren, wenn diese in nicht-technischer Sprache zugänglich sind. Die Aufgaben der Universitäten sind Forschung, Lehre und Information der Öffentlichkeit. Im Projekt "Next Generation" fassen die besten Masterstudierenden der Universität St. Gallen politikrelevante Ergebnisse der volkswirtschaftlichen Forschung populär zusammen. Mit diesem "Readers Digest" der Ökonomie leisten sie einen wichtigenBeitrag zur dritten Mission der Universität.
A question of increasing interest to researchers in a variety of fields is whether the biases found in judgment and decision-making research remain present in contexts in which experienced ...participants face strong economic incentives. To investigate this question, we analyze the decision making of National Football League teams during their annual player draft. This is a domain in which monetary stakes are exceedingly high and the opportunities for learning are rich. It is also a domain in which multiple psychological factors suggest that teams may overvalue the chance to pick early in the draft. Using archival data on draft-day trades, player performance, and compensation, we compare the market value of draft picks with the surplus value to teams provided by the drafted players. We find that top draft picks are significantly overvalued in a manner that is inconsistent with rational expectations and efficient markets, and consistent with psychological research.

In 25 concise steps, you will learn the basics of blockchain technology. No mathematical formulas, program code, or computer science jargon are used. No previous knowledge in computer science, ...mathematics, programming, or cryptography is required. Terminology is explained through pictures, analogies, and metaphors.This book bridges the gap that exists between purely technical books about the blockchain and purely business-focused books. It does so by explaining both the technical concepts that make up the blockchain and their role in business-relevant applications.What You'll LearnWhat the blockchain isWhy it is needed and what problem it solvesWhy there is so much excitement about the blockchain and its potentialMajor components and their purposeHow various components of the blockchain work and interactLimitations, why they exist, and what has been done to overcome themMajor application scenariosWho This Book Is ForEveryone who wants to get a general idea of what blockchain technology is, how it works, and how it will potentially change the financial system as we know it
Using Economic Indicators in Analysing Financial Marketsis an invaluable resource for investors, strategists, policymakers, students, and private investors worldwide who want to understand the true ...meaning of the latest economic trends to make the best decisions for future profits on financial markets.
This paper uses NASDAQ order book data for the S&P 500 exchange traded fund (SPY) to examine the relationship between one-minute, informational market efficiency and high frequency trading (HFT). We ...find that the level of efficiency varies widely over time and appears to cluster. Periods of high efficiency are followed by periods of low efficiency and vice versa. Further, we find that HFT activity is higher during periods of low efficiency. This supports the argument that HFTs seek profits and risk reduction by actively processing information, through limit order additions and cancellations, during periods of lower efficiency and revert to more passive market-making and rebate-generation during periods of higher efficiency. These findings support the argument that the adaptive market hypothesis (AMH) is an appropriate description of how prices evolve to incorporate information.
