Першин, А. Д., Pershin, A. D. January 2023 (has links)
Объектом настоящего исследования являются алгоритмы и методы машинного обучения, и их применение в задачах прогнозирования временных рядов и анализа текста. В данном исследовании предложено применить модифицированную архитектуру рекуррентной нейронной сети (LSTM) для предсказания цены закрытия криптовалютных котировок на следующий день от текущего, а также, применить алгоритмы классификации, такие как: логистическая регрессия, Linear SVC, Gradient Boosting, для определения эмоциональной метки новостной записи для разработки стратегии прогнозирования точек входа и выхода из торговых позиций на рынке криптовалют. Исследование фокусируется на доказательстве того, что применение методов и алгоритмов машинного обучения для создания торговой стратегии для определения точек входа и выхода из торговой позиции, повысит эффективность процесса торговли, а также, ускорит процесс сбора и обработки аналитических данных для технического анализа рынка. Для обучения используемых моделей, разработаны и использованы программные средства (парсеры), с помощью которых извлекаются данные с криптовалютной торговой биржи Binance, а также, криптовалютной социальной сети CryptoPanic. Экспериментальные результаты показывают, что среднем автоматизированный процесс определения точек входа и выхода из торговых позиций быстрее в 2 раза чем при ручном определении, а количество сделок увеличится примерно на 17.5%. В итоге можно сделать вывод о том, что, используя передовые технологии возможно разработать инструмент для повышения эффективности торговли криптовалютой. / The object of this study is the algorithms and methods of machine learning, and their application in the problems of time series forecasting and text analysis. In this study, it is proposed to apply a modified architecture of a recurrent neural network (LSTM) to predict the closing price of cryptocurrency quotes the next day from the current one, and also to apply classification algorithms, such as: logistic regression, Linear SVC, Gradient Boosting, to determine the emotional label of a news entry to develop a strategy for predicting entry and exit points for trading positions in the cryptocurrency market. The study focuses on proving that the use of machine learning methods and algorithms to create a trading strategy to determine entry and exit points from a trading position will increase the efficiency of the trading process, as well as speed up the process of collecting and processing analytical data for technical market analysis. To train the models used, software tools (parsers) were developed and used, with the help of which data is extracted from the Binance cryptocurrency trading exchange, as well as the CryptoPanic cryptocurrency social network. Experimental results show that, on average, the automated process of determining entry and exit points from trading positions is 2 times faster than with manual determination, and the number of transactions will increase by about 17.5%. As a result, we can conclude that, using advanced technologies, it is possible to develop a tool to improve the efficiency of cryptocurrency trading.

全球運籌管理模式下資訊系統架構之研究-以國內筆記型電腦產業為例

許良誠 Unknown Date (has links)
近年來,速度已經成為企業全球化競爭的關鍵要素,但企業無法單憑一己之力,及時地突破技術或市場上的瓶頸,因此,企業需專注於對自身具競爭優勢之價值活動,並集中力量維持與強化企業生存之核心資源,建立不易被取代之優勢,再透過產業間的分工,將產品從研發、設計、製造、組裝、行銷、售後服務,藉由分佈全球不同區域與不同國家的公司分別進行,共同塑造出具備彈性、速度與競爭力的合作方式,而此也就是全球運籌模式(Global Logistics)。其中資訊系統更為全球運籌模式的中樞,擁有完整的資訊系統,才可將分散全球的銷售、生產、庫存、出貨等資訊加以蒐集及整合,並提供做為迅速分析、預測、反應的依據。   筆記型電腦產業是目前台灣最具發展潛力的產業之一,而且台灣筆記型電腦產業所面臨的是國際化的競爭,業者一定要具備優良之全球運籌管理能力才可能接獲國際系統大廠之訂單,所以全球運籌管理對於筆記型電腦代工業者而言是非常重要的課題。因此,本研究將先藉由相關文獻的深入探討,分析目前國內外學者已經提出來之全球運籌管理模式資訊系統架構,接著歸納整理出全球運籌管理運作模式,再針對國內筆記型電腦產業現存問題的分析、現況觀察後,提出符合國內筆記型電腦產業之一般性全球運籌模式(General Global Logistics Models),並將依循著此模式,提出一個可行的全球運籌管理模式之資訊系統架構,最後利用雛型系統之建置,驗證其可行性。希望透過此資訊系統架構,使資訊流能跨越組織藩籬順暢地在供應鏈中往返,使整個供應鏈就像是一個虛擬企業,縮短產品上市時間,以最少成本、最低存貨,提供顧客最大的滿意度。 / In recent years, ”Speed” is a critical factor determining the competitive edge of globalized enterprises. For this reason, a successful manufacturer must first carefully maintain its competitive edge and do its best to increase its core resources for existence before seeking for cooperation of other companies in different areas of different countries to carry out R&D activity, design, manufacturing, assembling, marketing and after-sales service. When these companies cooperatively achieved the complete process of production based on a world industrial labor division system, they created a cooperative method with features of flexibility, speediness and competitiveness. And this is a start of global logistics models. Among these global logistics models, information system is regarded as a hub. With a complete information system, the manufacturer may collect and systematize the information of its marketing, production, stock and delivery coming from different countries and may also make analyses, predictions and responses on this systematized information.   The notebook computer industry is now regarded as one of potential industries in Taiwan. What this industry is faced with is the fierce competition on the global market. A notebook computer manufacturer, who lacks the ability to manage global logistics, cannot obtain orders from world leading buyers of reputable systems. In other words, world logistics management is a very important issue to OEM manufacturers of notebook computers. In this research, the first focus is placed on discussion and analysis made, in accordance with related literature, on the framework of information system built on global logistics management models submitted by domestic and overseas modern scholars. From this discussion and analysis is drawn an operating model of global logistics management. Besides, accompanying an analysis given to the existing problem and an observation given to the present situation of this industry, general global logistics models that meet with the demand of domestic notebook computer industry and the framework of information system built on feasible global logistics management models is submitted. Finally, verification is given to this feasibility through the erection of a model system. This information system is expected to make information flow more easily run in the supply chain over structural barriers and the entire supply chain serve as a simulated enterprise so that products can be more quickly put on the market and customers are satisfied with the least cost and the lowest stock rate.

Ermittlung der Zukunftsfähigkeit unternehmensweiter Anwendungssysteme / A process model for determination of future suitability of business application systems

Gronau, Norbert January 2005 (has links)
Bei Entscheidungen über abzulösende oder neue Anwendungssysteme kann mit Hilfe funktionaler Anforderungen immer nur der gegenwärtige oder vorhersehbare Bedarf ermittelt werden. In einem turbulenten Umfeld sind die Anwendungssysteme jedoch häufig langere Zeit im Einsatz als die Anforderungen gültig sind, mit Hilfe derer sie ausgewählt wurden. An der Universität Potsdam wird im Rahmen des BMBF-Projektes CHANGE eine Vorgehensweise zur Ermittlung der Zukunftsfähigkeit unternehmensweiter Anwendungssysteme entwickelt, deren wesentliche Merkmale in diesem Beitrag beschrieben werden. / A process model for determination of future suitability of business application systems: <br><br> Before decisions concerning reinvestments or additional usage of business application systems can be made, functional requirements depending on the actual or foreseeable demand are collected. In turbulent circumstances business application systems like ERP systems are longer used than the requirements for their choice are valid. At the university of Potsdam within the german research project CHANGE a process model was developed which is able to determine the future suitability of business application systems investigating possible turbulences on the market and around the company. <br> ---------<br> © GITO mbH Berlin

圖書流通業應用RFID資訊系統架構之探討

林家全, Lin, Chia-Chuan Unknown Date (has links)
圖書出版業,包含出版中外圖書、雜誌、有聲出版品與報紙等。近年來,圖書出版業快速發展,國內圖書產量遽增,各種外文書也大量進入台灣市場。這對圖書業者而言,圖書品項管理與流通複雜度也隨之增加。而圖書流通業者,負責圖書批發、運輸倉儲與零售等,上游有多家出版社,而下游面對更多的零售業者,其擁有圖書種類與數量豐富,所以圖書管理複雜度比其他上游出版業者、下游零售業者更複雜。 無線射頻識別系統(Radio Frequency Identity,RFID),以RFID標籤辨識物件(棧板、物流箱,單品)獨特的產品電子碼(Electronic Product Code,EPC),並由建置在各地的讀取器和RFID中介軟體,記錄和擷取對應的物件資訊,對於存貨及物流管理來說,RFID出現帶來新方法讓貨品管理與追蹤變得更有效率。把流動於供應鏈的物件貼上RFID標籤,再以共用EPC網絡服務平台(EPC Network Service Platform)作為資訊共享,則將使物件在供應鏈上下游的資訊能見度(Visibility)更加提昇。 本研究先蒐集RFID相關文獻,而後選定對於RFID有基本認識、知道RFID應用方式的圖書流通公司,了解公司對RFID需求及應用方式,再針對業者的需求與應用方式做分析,即完成業者的RFID需求資訊分析,而後對於業者需求,提出一套RFID資訊系統參考架構,以滿足其對RFID的需求。接著再與個案公司訪談,參酌業者意見,進行參考架構驗證與修正,最後圖書流通業者應用RFID資訊系統架構呈現。而結論部分,則為本研究作個總結,並為後繼的研究者提出相關研究建議。 / Publishers publish magazines, books, videotapes, newspapers etc. When it comes to publishing, it is recently developed very rapidly. Many kinds of books have popped up in book industry and have lead to complexity of books management and distribution. Book distributors play important roles in book distribution and retail. Distributors get the books from publishers and send the books to retailers. Distributors have more books than publishers and retailers, so they face much more management complexity. RFID can identify the object and learn its EPC by reading the object’s RFID tag. We can learn the object’s position by building RFID readers and RFID middlewares at the supply chain nodes. Due to RFID’s track and trace function materialflow and inventory management can enhance. Besides RFID, EPC Network Service Platform can strengthen information sharing between partners and lead to high visibility in the supply chain. We collected RFID references and selected book distributors. These book distributors have known RFID. We tried to understand the RFID requirements of the book distributors and then did the RFID requirements analysis of the book distributiors. Based on the RFID requirements analysis, we proposed a RFID system architecture to satisfy the RFID requirements of the book distributors. Following, we interviewed the book distributors and then verified, revised the RFID system architecture. At last the final RFID system architecture is presented and the architecture is offered to book distributors for reference. About the conclusion, we offered some research suggestions for other RFID researchers.

Implementace informačního modelu v prostředí systémové architektury / Information model implementation in systems architecture

Pořádek, Jiří January 2013 (has links)
This thesis deals with a field of information modeling and its relation to systems architecture. It is divided into two notional parts -- theoretical (first and second chapter) and practical (third and fourth chapter). First chapter explains the meaning of the term 'information model', compares it to the term 'data model' and then introduce its practical use in an enterprise modeling. It also defines the term of 'systems architecture' in its broad meaning and reduces it to three narrow meaning -- enterprise architecture, information architecture and information systems architecture, while it explains their relation to the information modeling. Finally this chapter provides the base for information model implementation methodology created later in the practical part of this thesis. Second chapter introduces architecture framework called TM Forum Frameworx specialized for a telecommunication services provider. It consists of three standards for business process, information and application architecture. The second one defines specific information model which is described partly in the second chapter and partly in the appendix B of this thesis. Third chapter describes the first of two contributions of this thesis - the information model implementation methodology. This methodology is applicable to any implementation of an information model. Three sections of this chapter contains diagrams and description of three phases of the methodology - pre-implementation phase, implementation phase and post-implementation phase. In the end of the chapter there is a table containing outputs of every single activity performed during all the phases. Fourth and last chapter then describes and evaluates real implementation of the information model from TM Forum Frameworx in the systems architecture department of an enterprise providing telecommunication services. This implementation based on the created methodology and its successful results then became the second contribution of this thesis.
