Integration mellan system : En undersökning av olika framgångsfaktorer / Integration of systems : A review of different success factors

Pasic, Anel, Cetinkaya, Talat January 2013 (has links)
This paper exposes the problems and challenges organizations face when integrating aged systems, web based systems and web services. The paper focuses on how people with different titles in an organization experience systems integration and the factors that contribute to project failure or success. The research methodology used in this is Grounded Theory and the resulting theory of this paper has taken form through the coding of transcribed interviews, which have gone through a constant comparing to other theories in the area of interest, mostly articles about success factors in system integration. The resulting outcome is a success model aimed to describe the underlying indicators to achieve project success. The success model consists of three factors that contribute to success in integration projects. The factors are: globalization, governance and balance. Integration projects are very complex in nature, more so than normal projects as there are more stakeholders involved and more interests to take into consideration. Due to the complex nature of integration projects, the need for a holistic view arises. It's crucial for an integration project that stakeholders take the interests and needs of other projects taking place simultaneously into consideration. The governance aspect of systems integration deals with the planning of strategies, communication and cooperation with other stakeholders involved within the integration project. It's crucial for integration projects to shift focus from individual goals and individual interest to mutual goals and interests. The third and final factor contributing to success in integration projects is balance. The balance between technical issues and organizational issues is crucial for the success of projects. It's very common that organizations focus on technical issues and neglect the organizational issues.

Unterstützung von Integrationsdienstleistungen durch abstrakte Integrationsmuster

Pero, Martin 15 April 2013 (has links) (PDF)
Integration ist eine fortwährende Aufgabe in betrieblichen Informationssystemen. Durch den Einsatz verschiedener personeller und maschineller Aufgabenträger kommt es zu wiederkehrenden Integrationsproblemen, die vorrangig durch externe Dienstleister gelöst werden. Das zentrale Problem dieser Arbeit ist, dass in der Wissenschaft diskutiertes Lösungswissen in Form von Mustern existiert, aber keinen Eingang in die Praxis findet. Um dieses Problem zu untersuchen, wurde eine qualitative empirische Untersuchung durchgeführt, welche erstmals im deutschsprachigen Raum Wirkungszusammenhänge und Entscheidungsmechanismen in Integrationsprojekten analysiert. Als Ergebnis der qualitativen Erhebung kann festgehalten werden, dass dem Dienstleistungscharakter der Integration bisher zu wenig Beachtung geschenkt wurde und dass Integrationsmuster nicht eingesetzt werden, weil der Abstraktionsgrad des so konservierten Lösungswissens nicht zum Abstraktionsgrad der Problemstellungen passt. Deshalb definiert die Arbeit zunächst ein Dienstleistungsmodell der Integration, welches sich auf die empirische Untersuchung stützt. Danach wird auf der Grundla-ge einer eigenschaftsbasierten Definition von Integrationsmustern eine Grundmenge an Mustern aus der Literatur extrahiert, die weiter abstrahiert werden. Als Abstraktionsprinzipien werden die Klassifikation und die Generalisierung eingesetzt. Abstrakte Integrationsmuster können als Ressourcen in ein Dienstleistungsmodell eingehen. Für die Klassifikation wurde ein erweiterbares und flexibles Klassifikationsverfahren – die Facettenklassifikation – gewählt. Diese ermöglicht jederzeit das Hinzufügen weiterer Facetten. Die Einordnung eines Musters muss nur innerhalb einer Facette disjunkt sein, es kann aber in andere Facetten eingeordnet werden. Die verwendeten Facetten entstammen sowohl dem Problem als auch dem Lösungsbereich. Jeder Facette liegt eine umfassende Analyse zugrunde. Die Klassifikation bildet den Ausgangspunkt der erneuten Generalisierung. Muster mit ähnlichen bzw. identischen Ausprägungen werden erfasst und auf ein gemeinsames Konzept untersucht. Diese Generalisierung wurde exemplarisch für zwei Mustergruppen durchgeführt. Dabei wurden die beiden abstrakten Integrationsmuster „zusätzlicher Zugriffspunkt“ sowie „Vermittler“ identifiziert. Die entwickelten Konzepte flossen in eine umfangreiche Evaluation ein, welche am Beispiel einer konkreten Dienstleistung im Bereich der E-Procurement-Integration durchgeführt wurde. Die Unabhängigkeit der Bewertung konnte dadurch sichergestellt werden, dass weder der Dienstleister noch der Kunde an der zuvor durchgeführten empirischen Untersuchung beteiligt waren. Der erarbeitete Lösungsvorschlag wurde in einer Laborumgebung implementiert. Das vollständige Integrationsszenario ist dabei auf der Basis einer Virtualisierungsumgebung realitätsnah nachgebildet worden. Neben Instanzen der Kundensysteme mit identischem Versions- und Patch-Stand kamen auch Datenbestände aus Produktivsystemen zum Einsatz. Die Integrationshilfsmittel wurden ebenfalls in der Laborumgebung eingerichtet. Durch abstrakte Integrationsmuster verbessert sich die Dienstleistungserbringung. Auf der Kundenseite bewirkt dies eine Verbesserungen der Integrations- und Unternehmensarchitektur sowie die Erschließung weiteren Verbesserungspotenzials. Für den Dienstleister ergibt sich neben einem veränderten Dienstleistungsmodell vor allem die Möglichkeit, einmalige Angebote in ein konfigurierbares Standarddienstleistungsangebot zu überführen. Zusätzlich kann eine verbesserte Ressourcennutzung (vor allem der Humanressourcen) anhand des veränderten Dienstleistungsmodells nachgewiesen werden. Im Rahmen der Arbeit konnte so ein Ansatz entwickelt werden, der die empirisch belegten Abstraktionsprobleme behebt und die Einsetzbarkeit von bestehendem Lösungswissen verbessert. Gleichzeitig werden die Wirkungsmechanismen und Entscheidungszusammenhänge durch das Dienstleistungsmodell besser erfass-, erklär- und vor allem planbar.

MCAD - ECAD integration: constraint modeling and propagation

Chen, Kenway 14 October 2008 (has links)
Mechatronic systems encompass a wide range of disciplines, including mechanical and electrical engineering, and hence the development process for mechatronic system is collaborative in nature. Currently the collaborative development of mechatronic systems is inefficient and error-prone because contemporary design environments do not allow sufficient information flow of design and manufacturing data across different engineering domains. Mechatronic systems need to be designed in an integrated fashion allowing designers from multiple engineering domains to receive updates regarding design modifications throughout the design process. One approach to facilitate integrated design of mechatronic systems is to integrate mechanical with electrical engineering CAD systems. Currently there exist numerous techniques that were developed to support various levels of integration between CAD/CAE systems. Standardized data exchange formats, e.g., STEP and IGES, support information exchange between various different CAD and PDM systems. Multi-Representation Architecture (Peak et al.) supports the integration of geometric information in CAD tools with analysis information in CAE tools. Other integration techniques include the Core Product Model (developed at NIST), Active Semantic Networks (Roller et al.), Constraint Linking Bridge (Kleiner et al.), and others. All these techniques have their areas of focus as well as research gaps that need to be covered. One area that needs research attention is the information exchange between mechanical and electrical domains, which is the focus of this thesis. In this thesis, the information exchange between mechanical and electrical domains is explored from two perspectives: conceptual design perspective, in which constraint relationship between attributes of mechanical and electrical components is identified and classified based on the physical forms, functions, and behavior of the mechatronic system; system realization perspective, in which the identified constraints are modeled for propagation between MCAD and ECAD systems. SysML is used to model the constraints between mechanical and electrical components. By means of an illustrative example (a robot arm), the constraint modeling and propagation developed in my thesis are demonstrated and implemented utilizing a MCAD system (SolidWorks) and an ECAD system (EPLAN Electric P8).

Orientadores: Joao Mauricio Rosario, Carlos Alberto Mariotoni / Dissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Engenharia Mecanica / Made available in DSpace on 2018-08-10T18:38:42Z (GMT). No. of bitstreams: 1 Canato_DecioAlbino_M.pdf: 1316639 bytes, checksum: 03ff0dfdee3deb1d7b4e3db678e77539 (MD5) Previous issue date: 2007 / Resumo: A automação residencial é uma modernidade cada vez mais presente nas residências. As soluções tecnológicas disponíveis no mercado deixaram de ser vistas como um luxo para poucos e se tornaram sinônimo de conforto e segurança acessível a todos os usuários interessados. Para construtores e incorporadores, o diferencial é oferecer aos clientes uma infraestrutura de automação de modo a permitir que o morador possa adequar o conforto e a segurança às suas necessidades e orçamento. Programar as luzes e cortinas para criar um cenário agradável no ambiente, ou ainda acessar os sistemas de segurança de sua residência, seja por telefone ou através da internet, são algumas das soluções existentes e acessíveis no mundo da automação. Atualmente, para formar um mecanismo automático em uma residência basta ir a qualquer loja de construção civil e comprá-los sem muita dificuldade. A dúvida que gera quando se faz este tipo de automação, compradas em lojas faça você mesmo, ou seja, montadas em blocos e sem planejamento prévio, é a questão da integração entre os dispositivos automáticos, não existe uma comunicação entre eles, agindo de forma independente, criados sem uma modelagem pré-definida, gerando gastos e transtornos nos projetos atuais e futuros. Para que as diversas opções possam ser integradas de maneira única e pessoal, ou seja, de acordo com a escolha de quem irá utilizá-las, é necessária a criação de uma infra-estrutura adequada. Isto significa prever em projeto o cabeamento, a instalação elétrica e seus acessórios responsáveis pela distribuição de sinais de dados, voz e imagens pela residência O compromisso deste trabalho é a realização de uma integração de sistemas domésticos automatizados baseados na vasta experiência locada na indústria, visto através das modelagens e integrações de sistemas complexos, ou seja, transportar a tecnologia já dominada da automação industrial para uma tecnologia já não tão recente que é a automação doméstica / Abstract: Home autonomation is a modern feature that is becoming more common, nowadays technological solutions available are synonym of comfort and safety instead of being considered an expensive luxury. Different autonomation options are now acquirable for general costumers. For contractors and incorporate, the main issue is to offer an autonomation structure allowing the costumer to suit comfort and safety to the family budget. Programming light intensity and curtains for a nicer atmosphere, being able to reach home security system either using phone or internet are some of the solutions available for home autonomation. Nowadays, autonomation systems can be purchased in many different stores. The main issue related to this kind of commercially available autonomation is that the different parts of the system are not integrated and are not able to communicate, being a potential source of extra costs and problems. On the other hand, if the autonomation system is planned for a specific house, considering who is going to use the system, most problems could be avoided. Creating a specific autonomation project means plan the electric installation, the wires design and related accessories responsible for data distribution, voice and image storage. The aim of this work is to provide an integration of home systems based on the wide experience accumulated by industrial autonomation, exporting the well-known technology for home autonomation / Mestrado / Mecanica dos Sólidos e Projeto Mecanico / Mestre em Engenharia Mecânica

Condições de produção da tuberculose multirresistente: percepções do doente / Conditions of Multidrug-resistant tuberculosis production: perceptions of the sick

Jaqueline Garcia de Almeida 27 November 2012 (has links)
A tuberculose multirresistente (TBMR) - resistência simultânea a rifampicina e isoniazida, principais fármacos do esquema de tratamento da tuberculose (TB), gera mais ônus aos doentes e aos Serviços de Saúde, pois acarreta maiores custos, aumenta o tempo de tratamento e relaciona-se a prognósticos desfavoráveis. A TBMR ocorre devido à falha em algum princípio do tratamento, seja por parte dos profissionais e serviços de saúde, seja por questões ligadas ao doente. Frente a isso, o presente estudo objetivou identificar e analisar as condições de produção da TBMR relacionadas ao doente e seu entorno. Esta investigação foi realizada junto aos sujeitos em seguimento em um hospital de referência do interior paulista, entre janeiro de 2010 a janeiro de 2012. Foi utilizada a abordagem qualitativa. Por meio da análise dos prontuários médicos do serviço terciário, caracterizamos o universo do estudo - composto por todos os doentes já seguidos pela instituição, descrevendo e analisando dados sociodemográficos e clínicos correspondentes. Caracterizamos, também, a amostra estudada, formada por oito doentes de TBMR em seguimento, detalhando seu contexto de vida e trajetória com a doença, assim como a estruturação municipal para seu acompanhamento. A segunda etapa do trabalho constituiu na análise das percepções dos sujeitos a cerca do adoecimento por TB e pela forma MR. Os dados foram coletados por meio de entrevistas semi-estruturadas, gravadas e transcritas na íntegra. Os textos resultantes constituíram o corpus do estudo, organizado com recurso do software Atlas. Ti versão 7.0 e analisado sob o referencial teórico da Análise de Discurso, de matriz francesa. Os resultados da investigação baseiam-se na análise de três aspectos: percurso diagnóstico - em que é apontadas a percepção da doença e dos sintomas, as histórias pessoais e familiares do adoecimento por TB, o desenvolver até a obtenção do diagnóstico e as histórias de fracasso dos tratamentos convencionais; tratamento e acompanhamento dos casos MR - momento em que são discutidas questões ligadas a percepção do tratamento pelos doentes, as modalidades de supervisão empreendidas, os instrumentos e insumos fornecidos, além do apoio da rede familiar; coordenação da assistência - em que são analisadas as nuances da relação entre os diferentes serviços envolvidos na atenção ao doente, tanto dentro do mesmo nível assistencial quanto em sua intersecção com a atenção terciária, a fim de compreender suas fragilidades e promover as potencialidades para o tratamento dos sujeitos. Essas condições de produção mostraram-se complexas, ao passo que sofrem influência das peculiaridades da forma como os serviços locais de atenção organizando-se para atender esses doentes, além de questões relacionadas à trajetória de vida e doença desses sujeitos, apontando para a necessidade de ampliação do espaço de negociação dentro do sistema de saúde. / Multidrug-resistant tuberculosis - simultaneous resistance to rifampicin and isoniazid, the main drugs in the treatment for tuberculosis (TB), generates more onuses to patients and Health Services because it involves higher costs, increases the treatment time and relates to the unfavorable outcomes. MDR-TB occurs due to failure in some treatment principles, either by professionals and health services, or by patient issues. Concerning this, the present study aimed to identify and analyze the conditions of MDR-TB production related to the patients and their surroundings. This investigation was conducted with the subjects followed up in a referral hospital in São Paulo State, between January 2010 and January 2012. It was used a qualitative approach. By analyzing the medical records of the tertiary service, we characterized the universe of the study - consisting of all patients who were already followed by the institution, describing and analyzing the demographic and clinical data matching. We also characterized the sample, formed by eight MDR-TB patients in follow-up, detailing the context of their lives and the disease trajectory, as well as the municipal structure to monitor them. The second stage of the work consisted of analyzing the subjects\' perceptions about TB development and MR strain. Data was collected through semi-structured interviews which were recorded and fully transcribed. The resulting texts constituted the corpus of the study, organized using the Atlas.Ti software version 7.0 and analyzed from the theoretical framework of Discourse Analysis of French matrix. The results are based on analysis of three aspects: The first is diagnosis route - which shows the disease and symptoms perception of the patient, personal and family histories of TB development, the disease development until the diagnosis, and the failed conventional treatment stories. The second aspect was treatment and monitoring of MDR cases - when cases are discussed we focused on the following aspects: perceptions of treatment by patients, undertaken methods of supervision, instruments and inputs provided, and the familiar support network. The third is assistance coordination - where the nuances of the relationship between several departments involved in the patient care are analyzed, within the same care level as well as its intersection with tertiary care in order to understand their weaknesses and promote the potential treatments for the subjects. These production conditions proved to be complex whereas the local care services peculiarities influence the way they are organized to assist these patients, as well as aspects related to life and illness trajectory of these subjects, indicating the need of expanding the negotiation space within the health system

Integrationsplattformar inom hälso- och sjukvård : Avgörande egenskaper vid investering av integrationsplattform

Ceder, Jasmine January 2018 (has links)
Den här studien syftar till att undersöka och skapa en större förståelse för bakgrunden till val av integrationsplattform inom regionerna i Sverige. Integrationsplattformar inom hälso- och sjukvården är ett komplext område, delvis på grund av den politiska styrningen men även för att IT-hanteringen idag är decentraliserad. Författaren har tittat på valet som de olika regionerna har gjort utifrån strategiska, ekonomiska, tekniska, verksamhetsmässiga och kulturella egenskaper. Studien tittar även på skillnader beroende på om det är ett större respektive mindre landsting.   En integrationsplattform kan underlätta och agera en mellanhand samt låter systemen kommunicera med varandra utan att behöva en point-to-point koppling. Många av regionerna har en budget att förhålla sig till och vill bedriva sin verksamhet till så låg kostnad som möjlig utan att behöva påverka organisationen och deras processer. I dagsläget finns det ingen integrationsplattform som ligger i framkant till att stödja alla de olika behoven som de olika regionerna har och därav kommer varje region finna den lösning som är bäst för regionen.   I jämförelse med tidigare studier där de strategiska egenskaperna visas det att i den här studien att det främst de ekonomiska egenskaperna inom den offentliga verksamheten som är av störst betydelse. / This study aims to investigate and create a better understanding of why the different regions of Sweden have chosen their integration platform within the healthcare sector. Due to the decentralisation and political governance there is a complexity within the healthcare sector various integration platforms. The author has looked at the choices that the different regions have made based on strategic, economical, technical, operational and cultural characteristics. The various regions size is also investigated as a factor, making a distinction between higher and lower populated regions.   An integration platform acts as an intermediary, allowing the various systems to communicate with each other without having a point-to-point connection. At present there is no integration platform at the forefront of supporting all the different needs of the different regions, each region finds the solution that is best for itself.

A framework for successful SOA adoption in selected South African universities

Jacobs, Carmen 26 July 2013 (has links)
The demand for systems i·ntegration has become more and more significant in higher education as institutions want systems that provide coherent information with data that is up to date and not redundant and can seamlessly support the end user experience. Institutions have become more reliant on information systems to support both administrative functions and those involved in teaching, learning and research, but because each department supports a diverse array of computing platforms and applications, it becomes very difficult to integrate these systems. SOA is classified as an innovative approach to integrating existing systems involving the use of independent services that can be accessed without knowledge of the underlying platform implementation. Unfortunately, the SOA initiative will not be success if it is not understood and used correctly by various applications and systems throughout the organisation. SOA introduces complexity and challenges in systems integration, acceptance, governance, data, development planning, security and external opportunities. If an organisation does not embrace or enable change in each of these areas, it is not ready for the adoption of SOA. This research investigates the systems integration challenge in selected South African universities and explores factors for SOA adoption. The framework for the adoption of SOA comprises seven factors, of which Systems Integration is the most significant and represents an efficient starting point for institutions considering SOA adoption. Acceptance, Governance, Data, Development Planning, Security and External Opportunities are other factors of SOA adoption that require careful and thorough consideration before an institution can successfully adopt SOA. The results of this research emphasise the importance of being able to embrace change and innovation and modify strategies in order to reflect the constant changes required for the adoption of SOA. / KMBT_363 / Adobe Acrobat 9.54 Paper Capture Plug-in

Into the Black Box: Designing for Transparency in Artificial Intelligence

Vorm, Eric Stephen 11 1900 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / The rapid infusion of artificial intelligence into everyday technologies means that consumers are likely to interact with intelligent systems that provide suggestions and recommendations on a daily basis in the very near future. While these technologies promise much, current issues in low transparency create high potential to confuse end-users, limiting the market viability of these technologies. While efforts are underway to make machine learning models more transparent, HCI currently lacks an understanding of how these model-generated explanations should best translate into the practicalities of system design. To address this gap, my research took a pragmatic approach to improving system transparency for end-users. Through a series of three studies, I investigated the need and value of transparency to end-users, and explored methods to improve system designs to accomplish greater transparency in intelligent systems offering recommendations. My research resulted in a summarized taxonomy that outlines a variety of motivations for why users ask questions of intelligent systems; useful for considering the type and category of information users might appreciate when interacting with AI-based recommendations. I also developed a categorization of explanation types, known as explanation vectors, that is organized into groups that correspond to user knowledge goals. Explanation vectors provide system designers options for delivering explanations of system processes beyond those of basic explainability. I developed a detailed user typology, which is a four-factor categorization of the predominant attitudes and opinion schemes of everyday users interacting with AI-based recommendations; useful to understand the range of user sentiment towards AI-based recommender features, and possibly useful for tailoring interface design by user type. Lastly, I developed and tested an evaluation method known as the System Transparency Evaluation Method (STEv), which allows for real-world systems and prototypes to be evaluated and improved through a low-cost query method. Results from this dissertation offer concrete direction to interaction designers as to how these results might manifest in the design of interfaces that are more transparent to end users. These studies provide a framework and methodology that is complementary to existing HCI evaluation methods, and lay the groundwork upon which other research into improving system transparency might build.
