1 EINFÜHRUNG Der Beitrag diskutiert ein Vorgehensmodell zur Übertragung eines Vernetzungsansatzes für sehr kleine Wertschöpfungseinheiten, vornehmlich aus dem Maschinenbau, in die Domäne Dezentrale Energieversorgung. Es handelt sich dabei um den kompetenzzellenbasierten Vernetzungsansatz (KVA), ein Artefakt des DFG-Forschungsprojektes „Hierarchielose regionale Produktionsnetze“ (Sonderforschungsbereich 457). Das Lernen setzt die Analyse sowie das Erkennen und Verstehen des Forschungsgegenstandes KVA voraus. Von besonderem Interesse sind die Forschungsergebnisse zu den aufbau- und ablauforganisatorischen Grundbetrachtungen über die Zusammenarbeit von Kompetenzzellen. Können diese Ergebnisse einen wissenschaftlichen und praktischen Nutzen für die Organisation von Anbietergemeinschaften aus Stromerzeugern und -verbrauchern stiften? Dazu werden das Gestaltungskonzept Zwei-Ebenen-Kooperation und das Konzept der Kompetenzzelle untersucht. Für die Übertragung wird die Modellierungssprache Unified Modeling Language 2 (UML2) zur Beschreibung von Struktur, Funktion und Organisation vorgeschlagen.

Smart Card Packaging Process Control System

Siddiqi, Saad Ahmed January 2012 (has links)
The project focuses on the packaging process of the smart card manufacturing industry. The idea of the project concerns how to increase production packaging efficiency by introducing a control system. After taking an in-depth look at the current production environment, the following system goals were defined: packaging time reduction, cost reduction, decrease in human errors, and reducing the number of customer complaints. To achieve these goals, the thesis project was divided into the following tasks: discovering a feasible solution, actual system development, testing, and evaluation. The proposed system is based on hardware (i.e. barcode scanner, and barcode printer) integrated with customized control software. The barcode scanner acts as a bridge between the system and the production process by scanning a barcode printed on each product. The system prints the required information label for the product’s package according to the scanned product. This label is pasted on the product’s box and is used as a tracking tool during further production steps. The system is very flexible and suits any packaging model. Other functional properties maintained in the system include data security, product traceability, and real time production monitoring. Testing of the system was done in an actual production environment at an Oberthur Technologies manufacturing site. Two production lines were selected to test the system’s functionality, specifically the SIM card production packaging line and the Scratch card/ Bank Card production packaging line. The results obtained during the evaluation phase of the proposed system show that the proposed solution decreased the packaging processing time by (27.3%) over the previous values. Moreover, the resulting human error rate is close to (zero%). / Projektet fokuserar på förpackningen processen smartkortet tillverkningsindustrin. Tanken med projektet handlar om hur att öka effektiviteten produktionen förpackningar genom att införa ett styrsystem. Efter att ha tagit en fördjupad titt på den nuvarande produktionsmiljö, var följande systemkrav mål definieras: nedsättning förpackning tid, minskade kostnader, minskad mänskliga fel och minska antalet kundklagomål. För att uppnå dessa mål var examensarbetet indelad i följande uppgifter: att upptäcka en genomförbar lösning, faktisk systemutveckling, testning och utvärdering. Det föreslagna systemet bygger på hårdvara (dvs streckkodsläsare och streckkod skrivare) integreras med skräddarsydd styrprogram. Den streckkodsläsare fungerar som en bro mellan systemet och produktionsprocessen genom att läsa en streckkod tryckt på varje produkt. Systemet skriver den erforderliga informationen etiketten för produktens förpackning enligt den scannade produkten. Denna etikett klistras in på produktens ask och används som ett verktyg för spårning under ytterligare produktionssteg. Systemet är mycket flexibelt och passar varje förpackning modell. Andra funktionella egenskaper bibehålls i systemet inkluderar datasäkerhet, spårbarhet och i realtid övervakning av produktionen. Testning av systemet gjordes i en verklig produktionsmiljö i ett Oberthur Technologies tillverkningsanläggning. Två produktionslinjer valdes för att testa systemets funktionalitet, särskilt i SIM-kortet produktionen förpackning linje och skrapkort / Bank kortproduktion förpackningslinje. De resultat som erhållits under utvärderingsfasen av det föreslagna systemet visar att den föreslagna lösningen minskade tiden förpackningen behandling av (27,3 %) jämfört med föregående värden. Dessutom är den resulterande mänskliga fel som ligger nära (noll %).

Automatisierung unscharfer Bewertungsverfahren - Modellierung und prototypische Umsetzung am Beispiel von Virtual Reality Projekten

Zilker, Michael 15 November 2001 (has links)
Die Konfrontation mit innovativen IT-Technologien und deren Beurteilung gehört heute zu den Kernaufgaben des Informationsmanagements. Es muss permanent entscheiden, ob neue IT-Technolgien im Unternehmen nutzenstiftend eingesetzt werden können. Zur Beurteilung von IT-Projekten liefert die Teildisziplin des IT-Controllings, die Elemente der Wirtschaftsinformatik und des Controllings vereint, diverse Methoden und Ansätze. Diese Ansätze bilden die Basis für die vorliegende Arbeit, in der insbesondere der Aspekt der Nutzenbewertung von IT-Innovationen diskutiert wird. Bei der Bewertung von IT-Innovationen treten spezifische Probleme auf, denen der Autor mit der Fortentwicklung der vorhandenen Instrumente begegnet. Der Einsatz von unscharfen Methoden (Fuzzy Logik) führt zu einer adäquaten Darstellung von vagen Größen in Form von Zugehörigkeitsfunktionen. Durch den Einsatz von Regelbasen wird ein Expertenwissen repräsentiert, das die Analysemethode nach außen hin vereinfacht und somit zu einer effizienteren Nutzenbetrachtung führt. Die Auswahl und Initiierung von innovativen IT-Projekten wird durch ein Vorgehensmodell gestützt, das bei der fundamentalen Fragestellung nach Schwachstellen und Verbesserungspotentialen im Unternehmen ansetzt. Für diese Analyse wird auf die Erfolgsfaktorenanalyse zurückgegriffen, die durch individuelle Faktoren angepasst wird. Aus den analysierten Schwachstellen werden innovative IT-Projekte abgeleitet und definiert. Die Aufstellung der Nutzenkriterien erfolgt aus einem allgemeinen Nutzenkatalog, der mit den analysierten Erfolgsfaktoren korrespondiert. Die konkrete Bewertung der Projekte erfolgt durch die fuzzybasierte Nutzenbewertung und liefert prägnante Empfehlungen zu den einzelnen Projekten. Die Integration des Vorgehensmodells in das IT-Controlling erfordert eine automatisierte Form, die aufgrund der UML Notation generiert werden kann. Die prototypische Umsetzung und Verwendung der unscharfen Nutzenanalyse haben gezeigt, dass die Methodik für den praktischen Einsatz tauglich ist.

Enterprise Business Alignment Using Quality Function Deployment, Multivariate Data Analysis And Business Modeling Tools

Gammoh, Diala 01 January 2010 (has links)
This dissertation proposes two novel ideas to enhance the business strategy alignment to customer needs. The proposed business alignment clock is a new illustration to the relationships between customer requirements, business strategies, capabilities and processes. To line up the clock and reach the needed alignment for the enterprise, a proposed clock mechanism is introduced. The mechanism integrates the Enterprise Business Architecture (EBA) with the House of Quality (HoQ). The relationship matrix inside the body of the house is defined using multivariate data analysis techniques to accurately measure the strength of the relationships rather than defining them subjectively. A statistical tool, multivariate data analysis, can be used to overcome the ambiguity in quantifying the relationships in the house of quality matrix. The framework is proposed in the basic conceptual model context of the EBA showing different levels of the enterprise architecture; the goals, the capabilities and the value stream architecture components. In the proposed framework, the goals and the capabilities are inputs to two houses of quality, in which the alignment between customer needs and business goals, and the alignment between business goals and capabilities are checked in the first house and the second house, respectively. The alignment between the business capabilities and the architecture components (workflows, events and environment) is checked in a third HoQ using the performance indicators of the value stream architecture components, which may result in infrastructure expansion, software development or process improvement to reach the needed alignment by the enterprise. The value of the model was demonstrated using the Accreditation Board of Engineering and Technology (ABET) process at the Industrial Engineering and Management Systems department at the University of Central Florida. The assessment of ABET criteria involves an evaluation of the extent to which the program outcomes are being achieved and results in decisions and actions to improve the Industrial Engineering program at the University of Central Florida. The proposed framework increases the accuracy of measuring the extent to which the program learning outcomes have been achieved at the department. The process of continuous alignment between the educational objectives and customer needs becomes more vital by the rapid change of customer requirements that are obtained from both internal and external constituents (students, faculty, alumni, and employers in the first place).

Integration testing of object-oriented software

Skelton, Gordon William 08 1900 (has links)
This thesis examines integration testing of object-oriented software. The process of integrating and testing procedural programs is reviewed as foundation for testing object-oriented software. The complexity of object-oriented software is examined. The relationship of integration testing and the software development life cycle is presented. Scenarios are discussed which account for the introduction of defects into the software. The Unified Modeling Language (UML) is chosen for representing pre-implementation and post-implementation models of the software. A demonstration of the technique of using post-implementation models representing the logical and physical views as an aid in integration and system testing of the software is presented. The use of UML diagrams developed from the software is suggested as a technique for integration testing of object-oriented software. The need for automating the data collection and model building is recognized. The technique is integrated into the Revised Spiral Model for Object-Oriented Software Development developed by du Plessis and van der Walt. / Computing / D.Phil. (Computer Science)

具整合性與互通性會計與決策管理系統之資訊模式建立--以某全球化營運之高科技公司個案研究 / An Integral and Interoperable Information Model Design of Accounting and Decision Management System--A Global High-Tech Corp Case Study

石太基, Shih, Tai-chi Unknown Date (has links)
傳統會計與決策管理系統受限於現行財務會計報導的架構,並未儲存與財務無關,或不能以金額衡量的資訊,無法對非財務性決策提供有效的幫助。而資訊語意的差異更使得傳統會計與決策管理系統不易與企業內其他資訊系統互通,造成系統整合上的困擾,歷來不斷有學者探討會計與決策管理系統資訊模式建立之方法,以增進會計與決策管理系統資訊模式的有用性。 本研究提出會計與決策管理系統資訊模式建立之框架與方法,強調會計與決策管理系統之建構,應與企業策略發展整體考量,同時導入REA model整合企業整體資訊模式與財會專業資訊模式,並採用UML作為系統發展流程之塑模工具,編製系統發展有關文件,以利後續選擇解決方案的映對程序,確認解決方案符合使用者需求,及增進會計與決策管理系統在企業內的整合性與互通性。 / Traditional accounting and decision management information system cannot support non-financial decision making, because there is only stored financial information without non-financial information due to the current financial accounting reporting structure. The information semantic differences block interoperability between accounting and decision management information system within the organization. And it also has caused the challenge of enterprise information integration. Researchers strive to find viable information modeling process or method to help accounting and decision management information system to be constructed. This thesis presents accounting and decision management information system information modeling framework and process. The framework stresses the construction of accounting and decision management information system must connect with enterprise vision and strategy. It also adopts and expands REA model to integrate accounting information model and enterprise information model at information modeling process. UML is a high-level modeling tool to develop system processes. The goal is to provide a standard method to develop system blueprints beyond tool-specific system solutions and to apply UML modeling documents to map different system solutions and make sure the solution fit with user requirements, and improve the integration and interoperability for accounting and decision management information system design and development.

Domain Specific Modeling Support for ArCon / Stöd för domänspecifik modellering med ArCon

Azari, Leila January 2013 (has links)
One important phase in software development process is to create a design model of the system which follows all the architectural rules. Often the architectural rules are defined by the system architect and the system model is designed by the system designer. The architect defines the rules in a text file where no standard or pattern is followed. Therefore, there is always the risk of violating the architectural rules by the designer. So manual reviews on the system model should be done by the architect to ensure the system model is valid.In order to remove this manual checking which can be erroneous and time consuming ArCon (Architecture Conformance Checker) was developed by Combitech AB. ArCon is a tool which lets the architect define the architectural rules in the format of UML (Unified Modeling Language) models where the elements of the model have different meaning than the standard UML. ArCon can read this model and extract architectural rules from it and check the system model against those rules and then print all the rule violations.ArCon is an open source tool i.e. free for everyone to download and use. Currently, it supports Papyrus as the UML modeling tool. Papyrus is integrated to Eclipse platform and is a general purpose modeling tool. It supports users with all types of UML diagrams and elements.The idea for this thesis work was to implement a new feature for ArCon in order to facilitate the design process for system designers. The feature should provide the system designers only those types of elements which they are permitted to add to a specific fraction of the system model. The list of permitted element types should be extracted from the architecture model where all the architectural rules are defined in advance. This new support in ArCon was named Domain Specific Modeling (DSM) support.To evaluate the effect of DSM support on the system designers performance a few test sessions, called usability tests, were performed. The participants in the test sessions were a representative sample of software designers. After analyzing the data collected from the test sessions, the pros and cons of the new support were discovered. Furthermore, a few new ideas for enhancing DSM support were generated.
