The purpose of this bachelor's degree project is to address the problem of automation of a storing system complex enough to be able to understand and manage the most important and critical aspects of the storage plant. The plant has been designed and built in a simulation program called Simumatik due to its obvious simplicity in comparison to what it would take to assemble it in the real plant.Therefore, some technical aspects have been integrated in connection with OPC-UA and with programming of CODESYS. Thus, a system with a variety of components has been proposed in aim to get as close as possible to a storing plant and a real distribution. The system includes ten conveyors. The bags are moved from the filling station to a door where the next operator take each bag.In turn, the resolution of the problem has been tackled from a realistic and general point of view so that all the final objectives of automation systems are achieved, such as the design and organization of a plant, control, and supervision.In general terms, the outcome of the final degree project is a deep analysis of current production, and a new storing processes with an automation solution and leveled production line as well. This automation would increase the flexibility of the operator as well as decrease the number of tasks of the operator and therefore it would be more efficient. The project begins by facing a problem in which the limitations are defined beforehand, which meets a complex and new requirement according to the development of a final degree project. This is equivalent to designing a storing plant with all the transport and distribution equipment in combination with sensors that provide information on the system.

The goal of the project was to create independent system, which is able to supervise remote site using Ethernet network. It can measure temperature and check state of door magnetic contact. Gained information are sent over network to the cenral node, which is able to present them on web page. In the project are also discussed important network protocols needed for implementation of the system, hardware used for implementation and software of the system.

Syfte: Syftet med studien var att undersöka vilka styrkor och svagheter som medarbetare upplever i svenska Försvarsmakten utifrån konceptet lärande organisationer. Metod: Studien har genomförts med en kvantitativ ansats genom en tvärsnittsstudie som innehåller dels OSI-enkät som är uppbyggd på en likertskala och dels en innehållsanalys av en fritextfråga. Totalt har 100 medarbetare inom den svenska Försvarsmakten svarat på enkäten. Resultatet för surveyundersökningen har analyserats genom deskriptiv statistik och ANOVA medan innehållsanalysen har genomförts genom att svaren på en fritextfråga har delats in i olika kategorier. Resultat och slutsats: Studiens resultat visade på att svaren för faktorn positiv attityd avviker med ett lägre medelvärde jämfört med de andra faktorerna. Resultatet visade även på att anställningstid har påverkan för hur man upplever organisationen där personal anställd längre än 10 år tenderar svara med lägre poäng på enkäten som helhet med en viss variation mellan olika faktorer. Vi fann också att resultatet från innehållsanalysen styrker att faktorn positiv attityd är ett stort förbättringsområde och att den svenska Försvarsmakten står inför en rad utmaningar kopplat till personalfrågor så som arbetsmiljön och en hög arbetsbelastning. Respondenterna efterlyser ett helhetstänk över organisationen, systemförståelse och moderniserade kommunikationsfunktioner. Examensarbetets bidrag: Studien har gett ett teoretiskt bidrag genom att testa och validera mätverktyget OSI i en militär kontext samt ett praktiskt bidrag i form av en ökad förståelse för vilka utmaningar den svenska Försvarsmakten står inför. Den har även bidragit till en djupare förståelse för vilka åtgärder som behöver vidtas för att den svenska Försvarsmakten ska vara flexibel och modern i sin struktur. Förslag till fortsatta studier: Studien har väckt flera idéer för framtida studier inom lärande organisationer. Det skulle vara intressant att jämföra olika förbandsdelar inom den svenska Försvarsmakten mot varandra vilket skulle ställa högre krav på större underlag. Ett annat förslag är att jämföra resultaten mellan de som sitter i chefsbefattning och icke-chefsbefattning. / Aim: The purpose of this study was to investigate which strengths and weaknesses employees experience in the Swedish Armed Forces based on the concept of learning organizations. Method: The study has been carried out with a quantitative approach through a cross-sectional study which contains both a survey, structured on a Likert scale, and a content analysis where information has been collected via a questionnaire survey. A total of 100 employees within the Swedish Armed Forces responded to the survey. The results of the survey have been analysed using descriptive statistics and ANOVA, while the content analysis has been carried out by dividing the answers to a free text question into different categories. Results and conclusions: In summary, the study shows that the responses for the positive attitude factor stand out with a lower mean value compared to the other factors. Our data also shows that length of employment has an impact on how one experiences the organization, where staff employed for longer than 10 years tend to answer with lower scores on the survey as a whole with a certain variation between different factors. We also find that the results from the content analysis confirm that the positive attitude factor is a major area for improvement and that the Swedish Armed Forces are facing a series of challenges linked to personnel issues such as the work environment and the high workload that is currently present. The employees are calling for a holistic approach to the organization, system understanding and modernized communication functions. Contribution of the thesis: The study has made a theoretical contribution by testing and validating the measurement tool OSI in a military context as well as a practical contribution in the form of an increased understanding of the challenges the Swedish Armed Forces are facing. It has also contributed to a deeper understanding of what measures need to be taken in order for the Swedish Armed Forces to be flexible and modern in its structure. Suggestions for future research: The study has raised several ideas for future studies in learning organizations. We believe it would be interesting to compare different units within the Swedish Armed Forces against each other, which would place higher demands on a larger basis. In the background questions, we had also found it interesting to add and compare between those in managerial positions and non-managerial positions.

Die Industrie ist im Wandel. Die Grenzen zwischen Industrien, Anwendungsbereichen und Unternehmen verschwinden immer weiter, sind teils kaum noch in ihrer alten Ausprägung zu erkennen. Auch die industrielle Automation kann und sollte sich diesem Trend nicht entziehen. Immer mehr Technologien und Paradigmen anderer Bereiche gewinnen an Bedeutung. Hinzu kommt, dass die Anzahl und die Vielfalt an Geräten, Anwendungen, Anforderungen und Technologien stetig wächst. Diese Arbeit befasst sich mit Ansätzen, die es ermöglichen, einigen Aspekten der wachsenden Komplexität zu begegnen. Dabei handelt es sich um Technologien und Konzepte zum Thema Management, genauer zum Netzwerk-, System- und Dienste-Management. Ziel ist es nicht nur einen Ansatz zu finden, der gegenwärtigen Ansprüchen genügt, sondern auch noch für kommende Entwicklungen geeignet ist.

Este trabalho de pesquisa aprofunda o conhecimento associado aos sistemas de automação modernos baseados em redes de controle LonWorks®, visando torná-los mais facilmente utilizáveis como meios de implementar ambientes pervasivos. Para tanto, foi proposto um modelo de relacionamento dinamicamente reconfigurável entre dispositivos de uma rede de controle, que permite conferir a um sistema de automação distribuído algumas características previstas na computação pervasiva. É proposta uma extensão do modelo de objetos na tecnologia LonWorks®, utilizando conceitos de middleware, de forma a conferir aos módulos da rede a capacidade de auto-gerenciamento dinâmico, de modo a modificar os seus comportamentos à medida que novas situações sejam identificadas. A extensão proposta foi aplicada experimentalmente, visando a sua validação e refinamento, como o sistema de comunicação interno de uma empresa, substituindo os PABXs convencionais, considerado em maiores detalhes. Constatou-se a impossibilidade de sua implementação com a tecnologia LonWorks® atual, que utiliza conexões estáticas, necessitando de um operador ou integrador para configurá-las, caso não seja adotada a extensão proposta. Como estudo de caso o projeto de um PABX baseado na tecnologia LonWorks® foi avaliado e discutido, contribuindo para a geração de uma nova metodologia de concepção de sistemas de automação que possam atender algumas propostas previstas na computação pervasiva. É proposto integrar a Tecnologia da Informação e Comunicação, com as ações e os comportamentos convencionais que as pessoas apresentam. Essa metodologia proposta supera os desafios de projetistas de sistemas de automação de ambientes, em especial os prediais, e obtém integração entre processos de forma que as pessoas não percebam que estão interagindo com um computador, cuja presença deverá cada vez mais se tornar onipresente. Além de facultar interfaces fáceis e naturais, tem-se também a incorporação dos conceitos da computação sensível a contexto nos sistemas de automação. / Pervasive or ubiquitous computing, proposes the integration between the information and communication technology with the actions and common behaviors presented by people. One of the challenges that it imposes to the environmental automation systems developers, specially building automation developers, is that this integration is processed in such a way that people do not realize they are interacting with a computer, thus its presence becomes omnipresent. Besides the need of an easy and natural interface, there is also the need to incorporate the sensitive computing context to the automation systems. The current control networks utilized in automation systems, building, home and industrial control do not show resources that support the requirements of pervasive computing. This research intend to improve the knowledge associated to modern automation systems, based on LonWorks® control networks, viewing to make them more easily usable as ways to implement pervasive environments. For that, a dynamically settable relationship model was proposed between the intelligent devices of a control network, which allows providing some foreseen characteristics on pervasive computing in a distributed automation system. A LonWorks® technology object model extension is proposed, using middleware concepts, in a dynamic way, to modify behaviors when new situations are identified. The proposed extension was experimentally applied to a few use cases, aiming at its validation and refinement, such as the internal communication of a company, which replaces the usual PABX, which was considered in greater detail. The impossibility of its implementation was found with the current technology, without the use of the proposed extension. Those cases were evaluated and discussed, contributing to a new automation system concept technology that can support provided proposals on pervasive computing.
