System integration is a key enabler to maximize information value in an engineering context. The valuable information is normally represented by information models which play a decisive role in the implementation of system integration. The information models are designed to efficiently and effectively capture, process and communicate information among different functional and business units. However, use of the information models in implementing system integration is challenged by insufficient support from current settings of modeling architectures. This situation calls for new strategies to ease the use of information models. To address this challenge, this study presents a new twofold solution: Model driven system integration. It includes 1) a modeling architecture to guide the development of information models and 2) an integrated implementation process to guide the use of information models. Thus, this work improves practical applicability of an information model in its entire modeling lifecycle. The results contribute not only to the performance of modeling practices but also to improved understanding of information modeling in system integration. Implementation contexts and implementation models are introduced to develop an implementation-oriented modeling architecture. Further, the potential of information models as a knowledge base to sup-port implementation practices is identified. To concretely discuss behaviors and structures of information models, this study adopts ISO 10303 and the related standards as major references of existing information models. Case studies on model driven system integration validate this research in scenarios concerning kinematic modeling, kinematic error modeling, cutting tools classification and product catalogue modeling. Model driven system integration exhibits high efficiency in implementation, enhanced interoperability and increased value of information models. / <p>QC 20170519</p> / MPQP - Model driven process and quality planning / FBOP - Feature Based Process Planning / DFBB - Digital factory building blocks

Since the use of social media has evolved, the ability of its users to bully others has increased. One of the prevalent forms of bullying is Cyberbullying, which occurs on the social media sites such as Facebook©, WhatsApp©, and Twitter©. The past decade has witnessed a growth in cyberbullying – is a form of bullying that occurs virtually by the use of electronic devices, such as messaging, e-mail, online gaming, social media, or through images or mails sent to a mobile. This bullying is not only limited to English language and occurs in other languages. Hence, it is of the utmost importance to detect cyberbullying in multiple languages. Since current approaches to identify cyberbullying are mostly focused on English language texts, this thesis proposes a new approach (called Multilingual Cyberbullying Detection System) for the detection of cyberbullying in multiple languages (English, Hindi, and Marathi). It uses two techniques, namely, Machine Learning-based and Lexicon-based, to classify the input data as bullying or non-bullying. The aim of this research is to not only detect cyberbullying but also provide a distributed infrastructure to detect bullying. We have developed multiple prototypes (standalone, collaborative, and cloud-based) and carried out experiments with them to detect cyberbullying on different datasets from multiple languages. The outcomes of our experiments show that the machine-learning model outperforms the lexicon-based model in all the languages. In addition, the results of our experiments show that collaboration techniques can help to improve the accuracy of a poor-performing node in the system. Finally, we show that the cloud-based configurations performed better than the local configurations.

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.

La reconfiguration dynamique d'un logiciel peut être un auxiliaire utile pour adapter et maintenir des systèmes informatiques. Dans la plupart des approches, le système doit être interrompu pour que la reconfiguration puisse être exécutée. Cette interruption ne peut convenir aux systèmes temps-réel : il est nécessaires que les contraintes temporelles soient respectées, même lorsque le système est en train d'être reconfiguré.<br />Notre approche se base sur OSA+, un middleware temps-réel. Notre objectif principal est d'être capable de reconfigurer un (ou plusieurs) service lorsque le système est en fonction, avec un temps de non-réponse prévisible et prédéfini, c'est-à-dire un temps pendant lequel le système ne réagit pas à cause de la reconfiguration.<br />Trois approches différentes concernant le blocage ou le non-blocage d'un service sont présentées. Ces approches peuvent être utilisées pour réaliser un compromis entre le temps de reconfiguration et le temps de non-réponse.

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

L'Internet des Objets (IdO) et les Environnements Intelligents (EI) ont attiré beaucoup d'activités de recherche et développement au cours de la dernière décennie. Pourtant, de nombreuses applications IdO/EI d'aujourd'hui sont encore limitées à l'acquisition et au traitement des données de capteurs et de leur contexte, avec un contrôle, le cas échéant, utilisant soit des solutions de base ou demandant l'intervention humaine, loin du contrôle automatique qui est un facteur essentiel de promouvoir ces technologies. Cette thèse vise à apporter le savoir-faire de la théorie du contrôle et des systèmes réactifs dans le domaine IdO/EI pour arriver à une solution avec une méthode formelle pour l'aspect de contrôle qui fait défaut. Nous proposons l'extension d'un canevas logiciel pour une infrastructure générique et partagée IdO/EI qui offre des interfaces de haut niveau pour réduire l'effort de conception, et qui permet l'auto-configuration et l'adaptation des applications de contrôle sur des propriétés génériques de l'environnement sans intervention humaine en utilisant les connaissances générales sur le domaine qui s'appliquent à chaque instance cible de système IdO/EI. Dans cette infrastructure étendue, les entités physiques individuelles (y compris toutes les "choses", appareils électriques et sous-ensembles de l'espace) peuvent être regroupées comme des entités virtuelles par des propriétés communes afin de fournir un niveau d'abstraction plus élevé pour le contrôle et d'autres applications, ainsi qu'une meilleure adaptation aux changements des configurations au niveau inférieur. Sur le requis d'une solution générique et commun dénominateur partagée par toutes les applications de l'IdO/EI dans un environnement donné, nous proposons pour cette infrastructure, de modéliser les entités cibles supervisées et contrôlées, y compris les entités individuelles et de leurs regroupements, ainsi que les choses et les entités spatiales, par des automates à états finis, pour être en mesure d'appliquer la technique de la synthèse des contrôleur discrets (SCD) aux différents niveaux d'abstraction et de granularité. SCD est une méthode formelle qui construit automatiquement un contrôleur, s'il existe, en assurant les objectifs de contrôle exigés concernant le modèle de comportement du système donné en termes d'automates parallèles synchrones. Les langages de programmation BZR et les outils Sigali existants sont utilisés pour effectuer la SCD et de générer un contrôleur de manière automatique. Les modules logiciels nécessaires sont proposés dans l'implémentation tels que le module de maintenance de relation qui garde une association correcte entre les instances d'entités individuelles et les groupes, et répercute des commandes d'action du contrôle de haut niveau aux actionneurs correspondants. Ce module est destiné à évoluer plus tard vers une solution plus générique comme une base de données graphes comprenant à la fois la base de connaissances générales et relations spécifiques d'instance environnement. La résolution des conflits entre les objectifs de contrôle venant de contrôleurs concurrent est également indispensable en raison des objectifs de l'ouverture de la plateforme. Un simulateur de contexte basé sur Java a été développé pour simuler l'environnement de la maison au sein de plusieurs scénarios proposés pour la validation, tels que le contrôle de la charge électrique et l'adaptation au contexte de l'activité. / The Internet of Things (IoT) and Smart Environments (SE) have attracted a lot of research and development activities during the last decade. Yet many present-day IoT/SE applications are still limited to the acquisition and processing of sensor data and its context, with control, if any, using either basic solutions or requiring human intervention, far away from the automatic control which is an essential factor to promote the technologies. This thesis targets to bring knowhow from control theory and reactive systems to the IoT/SE domain to achieve a solution with a formal method for the missing control aspect. We propose the extension of a framework in order to build a shared generic IoT/SE infrastructure offering high-level interfaces to reduce design effort, and enabling the self-configuration and adaptation of control applications over generic properties of the environment without human interaction by using general knowledge over the domain that applies to each target instance of IoT/SE system. In this extended framework, individual physical entities (including all relevant "things", appliances and subsets of space) may be grouped as virtual entities by shared properties to provide a higher level abstraction for control and other applications and better adaptation to lower level configuration changes. Requiring a generic common denominator solution shared by all IoT/SE applications in a given environment, we propose for this infrastructure, to model by finite state automata the target entities to be monitored and controlled, including both individual entities and their groupings, as well as things and space entities, to be able to apply discrete controller synthesis (DCS) technique over any of these at different levels of abstraction and granularity. DCS is a formal method which constructs automatically a controller, if it exists, guaranteeing the required control objectives regarding to the given system behavior model in terms of synchronous parallel automata. The existing BZR programming language and Sigali tools are employed to perform DCS and generate a controller in an automatic way. Necessary supporting software modules are proposed in the implementation such as the relation maintenance module keeping the correct association between individual entity instances and groups, and dispatching the action orders from the high level control to corresponding actuators. This module would evolve later to a more generic solution such as a graph data base including both the general knowledge base and specific environment instance relations. Conflict resolution between objectives of control coming from concurrent controllers is also indispensable due to the intended openness of the platform. A java based context simulator has been developed to simulate the home environment within several scenarios proposed for the validation, such as electrical load control and activity context adaptation.

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.
