A framework for promoting interoperability in a global electronic market-space

Pather, Maree 30 June 2005 (has links)
The primary contributions to the area of electronic business integration, propounded by this thesis, are (in no particular order):  A novel examination of global Business-to-Business (B2B) interoperability in terms of a "multiplicity paradox" and of a "global electronic market-space" from a Complex Systems Science perspective.  A framework for an, integrated, global electronic market-space, which is based on a hierarchical, incremental, minimalist-business-pattern approach. A Web Services-SOA forms the basis of application-to-application integration within the framework. The framework is founded in a comprehensive study of existing technologies, standards and models for secure interoperability and the SOA paradigm. The Complex Systems Science concepts of "predictable structure" and "structural complexity" are used consistently throughout the progressive formulation of the framework.  A model for a global message handler (including a standards-based message-format) which obviates the common problems implicit in standard SOAP-RPC. It is formulated around the "standardized, common, abstract application interface" critical success factor, deduced from examining existing models. The model can be used in any collaboration context.  An open standards-based security model for the global message handler. Conceptually, the framework comprises the following:  An interoperable standardized message format: a standardized SOAP-envelope with standardized attachments (8-bit binary MIME-serialized XOP packages).  An interoperable standardized message-delivery infrastructure encompassing an RPC-invoked message-handler - a Web service, operating in synchronous and/or asynchronous mode, which relays attachments to service endpoints.  A business information processing infrastructure comprised of: a standardized generic minimalist-business-pattern (simple buying/selling), comprising global pre-specifications for business processes (for example, placing an order), standardized specific atomic business activities (e.g. completing an order-form), a standardized document-set (including, e.g. an order-form) based on standardized metadata (common nomenclature and common semantics used in XSD's, e.g. the order-form), the standardized corresponding choreography for atomic activities (e.g. acknowledgement of receipt of order-form) and service endpoints (based on standardized programming interfaces and virtual methods with customized implementations). / Theoretical Computing / PHD (INFORMATION SYSTEMS)

Vilken metod kan användas för att bredda IT-system mot nya marknader? : Framtagning av en utvecklingsprocess med tillämpning i en fallstudie. / What method can be used to broaden IT systems towards new markets? : Development of a development process with application in a case study.

Poyraz, Furkan, Sakalouski, Pavel January 2017 (has links)
Inom varje verksamhet förekommer det alltid någon form av projektplanering när man vill bedriva sin verksamhet på en ny marknad. Dessa typer av förberedelser görs på olika sätt och utmaningen för företagen blir att använda sig av rätt etableringsstrategi. För att lyckas med implementering av ett projekt, på respektive marknad som organisationer verkar på, är en utav framgångsfaktorerna att ha en tydlig och genomtänkt metod. Företaget Beta erbjuder molnbaserade tjänster inom tullhantering där man skapar lösningar som hjälper andra företag att hantera sina tullärenden. Aktören är etablerad på den svenska marknaden och vill prova att erbjuda sina IT-lösningar i Norge. Företaget har därför ett behov av att undersöka hur den norska marknaden ser ut, om det finns en möjlighet att bredda deras befintliga systemlösningar och i så fall hur de ska gå tillväga för att få ett fungerande system som kan kommunicera med norska tullverket. I rapporten föreslås en metod som kan användas som underlag vid utvidgning av en verksamhet till nya marknader. Utvecklingsprocessen som presenteras ska också kunna generaliseras, fungera som underlag och användas även av andra företag som ställs inför samma utmaning som Beta. Denna rapport innehåller även en analys av den norska marknaden. Det finns en jämförelse mellan delar av svenska och norska tullsystemet och en presentation av de ändringar som behöver göras utifrån skillnader som finns. Som resultat ger rapporten en tydlig bild av hur man möjligen kan gå tillväga för att ta sig an liknande problem. Författarna presenterar även ett resultat som beskriver en lösning till Betas problem. / Within each activity, there is always some kind of project planning when you want to do business in a new market. These types of preparation are done in different ways and the challenge for companies is to make use of the right establishment strategy. To succeed in implementing a project, on the respective market that organizations are working on, one of the success factors is to have a clear and thoughtful approach. The company Beta offers cloud-based customs management services, which provide solutions that help other companies handle their customs issues. Beta is established in the Swedish market and wants to try to offer their IT solutions in Norway. The company therefore has a need to investigate how the Norwegian market looks, if there is an opportunity to broaden their existing system solutions and, if so, how they should go about getting a working system that can communicate with the Norwegian customs office. The report proposes a method that can be used as a basis for expanding a business to new markets. The development process presented should also be generalized, serve as a basis, and used by other companies facing the same challenge as Beta. This report also contains an analysis of the Norwegian market. There is a comparison between parts of the Swedish and Norwegian customs system and a presentation of the changes that need to be made based on differences. As a result, the report provides a clear picture of how one might possibly be able to address similar problems. The project members also present a result describing a solution to Beta's problems.

A framework for implementing the VMI model in an MRO partnership

Altabba, Abdulrahman, Karlsson, Lina January 2016 (has links)
Purpose - The purpose of this paper is to investigate the feasibility of implementing the Vendor Managed Inventory (VMI) model in an MRO (maintenance, repair, and operations) partnership, and highlight its potential economic, environmental, and organizational benefits, as well as limitations. Approach - First, a comprehensive literature review was conducted on fields relevant to VMI. Second, empirical data was gathered from a single exploratory case study with Momentum Industrial, and its customer Stora Enso. Semi-structured interviews were used to gather data from the case companies. Findings - Results suggest that VMI results in benefits for the supply chain in general, such as reduced administration and inventory costs, improved service levels, reduced information distortion, and improved relationship among partners. For the particular case of VMI in an MRO partnership, improved service levels can be obtained by a reduced risk of production downtime for the customer. Moreover, the implementation of VMI has potential environmental benefits, such as reduced paper use, and higher transportation fill rate. Limitations of implementing VMI include the difficulty in system integration, and information sharing. Trust could be a potential issue that limits information sharing amongst supply chain partners. Moreover, the difference in organizational cultures and policies of partners should be taken into consideration. Limitations - The study is limited to opinions from one MRO customer in the paper and packaging industry. Even though the questions asked to informants in Momentum and Stora Enso tackled benefits to MRO customers in general, a broader image could have been achieved by interviewing customers from different industries. Moreover, the case companies do not currently adopt VMI in their partnership, so the case study results are based on what they think would be the potential benefits and limitations of implementing VMI in an MRO partnership. Practical Implications - This paper can serve as a guideline for logistics managers who are considering VMI in an MRO partnership specifically, as it provides them with the benefits and limitations associated with VMI. More generally, any company considering VMI can also benefit from the theoretical framework presented.

Investigation of Pyrimidine Salvage Pathways to Categorize Indigenous Soil Bacteria of Agricultural and Medical Importance and Analysis of the Pyrimidine Biosynthetic Pathway's Enzyme Properties for Correlating Cell Morphology to Function in All Phases of Growth

Meixner, Jeffery Andrew 05 1900 (has links)
This dissertation comprises three parts and is presented in two chapters. Chapter 1 concerns Arthrobacter, a bacterium with an intriguing growth cycle. Whereas most bacteria exist as either a rod or coccus, this bacterium shares the rod/coccus lifestyle. It therefore seemed important to examine the growth regulatory pathways from the rod and coccus. The committed step, that catalyzed by aspartate transcarbamoylase (ATCase), in the pyrimidine biosynthetic pathway was chosen. The ATCase in Arthrobacter is like the well known Pseudomonas enzyme except that it has an active dihydroorotase (DHOase) associated. Included in Chapter 1 is the description of a microorganism, Burkholderia cepacia, whose ATCase has characteristics that are at once reminiscent of bacteria, mammals, and fungi. It differs in size or aggregation based on environmental conditions. In addition, it has an active DHOase associated with the ATCase, like Arthrobacter. B. cepacia is important both medically and for bioremediation. Since B. cepacia is resistant to most antibiotics, its unique ATCase is a prime target for inhibition. Whereas the first chapter deals with the de novo pathway to making pyrimidines, which is found mainly in the lag and log phase, Chapter 2 addresses the salvage pathway, which comes more into play during the stationary phase. This section focuses on the isolation, identification, and grouping of a number of natural soil bacteria from various soil locations. These organisms are important agriculturally, medically, and industrially. Addition of these soil isolates to poor soils has been found to improve the soil. In a previous study by D.A. Beck, the salvage schemes for a number of laboratory strains of microorganisms were determined. Nine separate classes of salvage were designated by determining the salvage enzymes present. In this study emphasis has been placed on soil bacteria, which had not previously been analyzed. A number of species of soil bacteria were identified using the MIDI. The salvage enzymes were then determined for these organisms and a comparison of these isolates to the previous study was performed in order to group the new organisms into 19 salvage schemes, that is 10 more than in the previous study.

De gado a café: as ferrovias no sul de Minas Gerais (1874-1910) / From cattle to coffee: the railroads in the South of Minas Gerais state (1874-1910)

Silva, Marcel Pereira da 09 November 2012 (has links)
O presente trabalho tem como objetivo estudar três companhias férreas do sul da província e depois estado de Minas Gerais: E.F. Minas e Rio, Cia. Viação Férrea Sapucaí e Cia. E.F. Muzambinho, para entender, em termos de atividades econômicas, o que existia no Sul de Minas Gerais no advento de suas ferrovias, e o que mudou com a chegada e formação delas. Estas empresas serviram a maior parte do chamado Sul de Minas, uma região que possuía um quadro produtivo diversificado em nosso recorte cronológico. Os fluxos demonstravam uma forte tendência dos produtos sul mineiros ao comércio interprovincial/interestadual, principalmente com o Rio de Janeiro e São Paulo. As atividades relacionadas a agricultura e pecuária voltadas para o abastecimento ou consumo interno predominavam quando os trilhos são inaugurados, e a produção cafeeira ainda era incipiente, mas se expandia com consistência. Contudo, com o passar dos anos e o prolongamento dos trilhos, o perfil produtivo sul mineiro começa a se alterar. Não obstante o forte aumento da exportação de gado, o café caminha para se tornar o principal produto agrícola sul mineiro. Porém, os tradicionais produtos exportados pela região ainda continuam com forte presença até 1910, que é justamente o ano em que as três companhias são aglutinadas e forma-se a Companhia de Estradas Férreas Federais Brasileiras, CEFFB Rede Sul Mineira. Foi também muito importante a presença da Companhia Mogiana de Estradas de Ferro em alguns pontos da região, que captou boa parte da produção local e consequentemente desviou a exportação de localidades que utilizavam ou potencialmente poderiam utilizar os serviços das outras três companhias. / This research has the aim to study three Minas Gerais south railroads companies: E.F. Minas e Rio, Cia. Viação Férrea Sapucaí e Cia. Estrada de Ferro Muzambinho, to understand, in economics activities subjects, what existed in the south of Minas Gerais in outset of yours railroads, and what change their arrive and expansion. This enterprises served the great most south of Minas Gerais, a region that had a diversify production in later ninethy century. The outflow shown a strong tendence of south of Minas Gerais goods to the interprovincial interchange, Rio de Janeiro e São Paulo mainly. Agriculture and stock farming activities to the supply, predominated when the rails arrived, and the coffee production was still in the begin, but has expanded with force. However, along the years and with the rails expansion, the productive profile started change. Despite the strong growth of cattle exportation, the coffee walked to turn the main good of the south of Minas Gerais. However, the tradicionals exported goods still with great importance until 1910, the same year that the three companies are joined to creat the Companhia de Estradas de Ferro Federais Brasileiras, CEFFB Rede Sul Mineira. Too much important too was the presence of the Companhia Mogiana de Estradas de Ferro in some places of region, the captured a great part of local production and thereafter desviated the exportations of cities that used or potencialy could to use the services of the other ones companies.
