A Unified Framework for e-Commerce Systems Development : Business Process Pattern Perspective

Jayaweera, Prasad M. January 2004 (has links)
In electronic commerce, systems development is based on two fundamental types of models, business models and process models. A business model is concerned with value exchanges among business partners, while a process model focuses on operational and procedural aspects of business communication. Thus, a business model defines the what in an e-commerce system, while a process model defines the how. Business process design can be facilitated and improved by a method for systematically moving from a business model to a process model. Such a method would provide support for traceability, evaluation of design alternatives, and seamless transition from analysis to realization. This work proposes a unified framework that can be used as a basis to analyze, to interpret and to understand different concepts associated at different stages in e-Commerce system development. In this thesis, we illustrate how UN/CEFACT’s recommended metamodels for business and process design can be analyzed, extended and then integrated for the final solutions based on the proposed unified framework. Also, as an application of the framework, we demonstrate how process-modeling tasks can be facilitated in e-Commerce system design. The proposed methodology, called BP3 stands for Business Process Patterns Perspective. The BP3 methodology uses a question-answer interface to capture different business requirements from the designers. It is based on pre-defined process patterns, and the final solution is generated by applying the captured business requirements by means of a set of production rules to complete the inter-process communication among these patterns.

Esses modelos abrangem variadas informações sobre os recursos utilizados e interações entre diferentes setores e pessoas, evidenciando interdependências entre os processos. Contudo, esses modelos podem apresentar problemas de legibilidade e dificuldades de navegação à medida em que se tornam extensos. A representação do conhecimento implícito é complexa e não está padronizada; as interdependências nem sempre são fáceis de serem compreendidas. O uso de ontologias tem aberto uma perspectiva complementar para mitigar esses problemas e prover processos com semânticas acessíveis por máquina. As ontologias contribuem para a conceituação e organização da informação embutida e desestruturada que se encontra presente nos processos de negócio e que deve ser explorada. As ontologias são utilizadas para estruturar o conhecimento implícito que está presente nos processos de negócio, possibilitando a compreensão desse conhecimento por máquina. As ontologias também contribuem para o alinhamento das visões das equipes de negócio e de Tecnologia da Informação da organização. Nesse contexto, este trabalho apresenta um processo sistemático para gerar uma ontologia a partir de um modelo de processos de negócio em BPMN v2.0, permitindo consultar informações sobre o modelo. Uma ferramenta denominada PM2ONTO foi então desenvolvida, visando gerar a ontologia em OWL automaticamente e disponibilizar uma interface para consultas predefinidas, elaboradas na linguagem SPARQL. Os modelos de processos de negócio devem ser exportados para arquivos em XPDL v2.2, os quais serão as entradas do sistema PM2ONTO. As ontologias resultantes ficam disponíveis em um banco de dados para consultas e também podem ser manipuladas por outras diferentes ferramentas. A avaliação do processo sistemático apresentado neste trabalho foi feita com base em estudos de caso, usando modelos de processos de negócio de diferentes áreas e diferentes níveis de complexidade. / Aiming technical, managerial and strategic improvements, business process models have been used in organizational environments to understand the process chain. Although these models may present readability problems and navigation difficulties as they become extensive, they can cover many information about resources and interactions between different sectors and people, showing interdependencies among the processes. Interdependencies are not always easy to understand because of its complex and not standardized knowledge. The use of ontologies has opened a complementary perspective to mitigate these problems and to provide processes with machine-accessible semantics. Also, they contribute in the conceptualization and organization of the embedded and unstructured information that is present in the business processes and that must be explored. In order to ease machine knowledge, ontologies are used to structure the implicit knowledge in business processes. They also contribute to the alignment of the organization's business and IT teams. In this context, this work presents a systematic process to generate an ontology from a business process model in BPMN v2.0, allowing to query information about the model. In this way, PM2ONTO tool was developed aiming to generate the ontology in OWL automatically and to provide an interface for predefined queries elaborated in the SPARQL language. Business process models should be exported to files in XPDL v2.2, which will be the inputs of the PM2ONTO system. The resulting ontologies stay available in a database for queries and can also be manipulated by other different tools. The systematic process evaluation presented in this work was made based on case studies, using business process models of different areas and different levels of complexity.

However providing efficient business processes can demand high costs due to the need of software, hardware, and technical support. Cloud Computing emerged as a means for providing a fast and cheap way of acquiring computational resources in a pay-per-use manner, and can be employed for achieving efficient business processes with low costs. However, due to safety requirements, certain data or activities of a business process should be kept within the user premises, while others can be allocated to a cloud. This master dissertation presents a generic approach for decomposing business process taking into account costs, performance and safety requirements, thus granting greater reliability in the use of cloud resources. This approach is illustrated by means of a case study in the Healthcare domain. / Gerenciamento de Processos de Negócio emergiu como um meio para gerenciar e aperfeiçoar processos de negócio continuamente. Entretanto, fornecer tais processos de maneira eficiente pode demandar altos investimentos devido às necessidades de software, hardware e suporte técnico. Computação em Nuvem emergiu como um meio para prover uma forma rápida e barata de adquirir recursos computacionais com pagamento sob demanda, e pode ser aplicada para disponibilizar processos de negócio eficientes e com baixo custo. Entretanto, devido a requisitos de segurança, certos dados ou atividades de um processo de negócio devem ser mantidos na premissa do usuário, enquanto outros podem ser alocados em uma nuvem computacional. Esta dissertação de mestrado apresenta uma abordagem genérica para a decomposição de processos de negócio, que leva em conta custos, desempenho e requisitos de segurança, outorgando assim uma maior confiabilidade no uso de recursos de nuvens computacionais.

It is possible to automate some activities of business processes resorting to the use of Information Systems and accordingly decrease the execution time and increase the production. However, Information systems often suffer maintenance over time and become obsolete in their technologies and a reengineering process becomes necessary. In this case, the Business Knowledge, located more accurately the reality in information system source code, should be mantained. Thereof, in this work, we propose an Approach to support the Business Process Recovery from Source Code. The approach, entitled RPN, uses a static analysis technique of source code because it allows to analyze the source code without the need to modify and run the information system source code. Furthermore, the approach uses the Knowledge Discovery Metamodel (KDM) standard with a set of Heuristic rules to identify relevant code elements to the business layer. As result, Business Process Models are generated according to Business Process Model and Notation (BPMN) standard specification. This models, together with other software artifacts, provide more subsidies to the Software Reengineering process. To evaluate the proposed approach, a case study was performed in Academic Domain to measure the effectiveness of the approach compared to the other approaches and the manual process. The results exceeded expectations and prove that the approach is effective. / Ao longo do tempo, processos de negócio se tornaram um artefato chave para organizações, visto que esses processos permitem gerenciar o que acontece dentro de seus ambientes. É possível automatizar algumas atividades de processos de negócio recorrendo ao uso de sistemas de informação e, dessa forma, diminuir o tempo de execução dessas atividades e aumentar a produção. Entretanto, ao longo do tempo, sistemas de informação sofrem diversas manutenções e tornam-se obsoletos em suas tecnologias e um processo de reengenharia torna-se necessário. Nesse caso, o conhecimento do negócio, localizado mais precisamente à realidade no código fonte do sistema de informação, deve ser mantido. Por este motivo, este trabalho propõe uma abordagem para apoiar a recuperação de processos de negócio a partir do código fonte. A abordagem, nomeada RPN, recorre à técnica de análise estática do código fonte, uma vez que essa técnica permite analisar o código fonte de um sistema sem a necessidade de modificá-lo e executá-lo. Além disso, a abordagem utiliza o padrão Knowledge Discovery Metamodel (KDM) com um conjunto de regras de heurísticas para recuperar elementos de código relevantes à camada de negócio. Como resultado, são gerados modelos de processos de negócio de acordo com a especificação padrão Business Process Model and Notation (BPMN). Esses modelos, em conjunto com outros artefatos de software, fornecem maiores subsídios para o processo de reengenharia de software. Para avaliar a abordagem proposta, foi realizado um estudo de caso no domínio acadêmico para mensurar a eficácia da abordagem comparado às outras abordagens e ao processo manual. Os resultados obtidos foram satisfatórios e a abordagem RPN mostrou-se muito eficaz e eficiente para executar seu propósito.

Integração de modelos de processos de negócio com modelos de requisitos de software : um caso na área de saúde

Silva, Fernanda Gomes 23 August 2016 (has links)
The first steps in the software development life cycle are crucial for a successful software product. In this scenario, modeling activities play an important role in the requirements specification and other activities throughout the Project. Although the modeling activities of business processes and activities related to Requirements Engineering are recognized as important individually, some approaches have considered the integration of these activities. In this context, this master thesis proposes an approach and corresponding guidelines for integration of modeling software requirements with SysML and modeling of business processes and workflows with the support of BPMN. This relationship is represented with both graphical models and tabular format. Therefore, software developers can track business processes and software requirements already during the initial activities of the software development process. The proposed approach has been presented to a group of systems analysts, university professors and master students. These participants answered to a questionnaire based on TAM theory mostly agreeing that integrating BPMN and SysML will contribute positively for documentation , validation and tracking requirements. Despite their interest in learning more about the two languages, they declared di culty in performing integration and the cost to use this proposal in projects in industry. This work has also presented a report of the experience in HU / UFS and a guide to integration of BPMN and SysML to assist the development of a patient’s Electronic Health Record in a public hospital. / Os primeiros passos no ciclo de vida de desenvolvimento de software são cruciais para um produto de software bem sucedido. Neste cenário, as atividades de modelagem desempenham um papel importante na especificação de requisitos e demais atividades em todo o projeto. Embora as atividades de modelagem de processos de negócio e as atividades relacionadas com a Engenharia de Requisitos sejam reconhecidas como importantes individualmente, algumas abordagens têm considerado a integração destas atividades. Neste contexto, este trabalho propõe uma abordagem e orientações correspondentes à integração dos modelos de processos de negócio elaborados com BPMN e modelos de requisitos de software com SysML. Essa relação é representada tanto com modelos gráficos como em formato tabular. Portanto, os desenvolvedores de software podem rastrear os processos de negócio e requisitos de software já durante as atividades iniciais do processo de desenvolvimento de software. A abordagem proposta foi apresentada a um grupo de analistas de sistemas, professores universitários que lecionam a disciplina Engenharia de Software e estudantes de mestrado do curso de Ciência da Computação da Universidade Federal de Sergipe, e respondendo a um questionário baseado na teoria TAM afirmaram que a integração BPMN e SysML irá contribuir positivamente nas atividades de documentação, validação e rastreamento de requisitos. Apesar do interesse em aprender mais sobre as duas linguagens, os participantes na pesquisa declararam a dificuldade em realizar a integração e o custo em utilizar esta proposta em projetos reais. Neste trabalho foi ainda apresentado um relato da experiência no Hospital Universitário da Universidade Federal de Sergipe (HU/UFS) e um guia para integração de modelos elaborados com BPMN e SysML, para auxiliar o desenvolvimento de um prontuário eletrônico do paciente em um hospital público.

Srovnání standardů pro procesní modelování / Comparison of standards for process modeling

Kalina, Jaroslav January 2008 (has links)
The scope of this thesis is the field of business process modeling and additionally the usability of business process models in areas like conceptual analysis of IS/ICT, business process reengineering and business process management. For the purpose of evaluation of the usability of current standards for business process modeling, an framework for comparison of various characteristics of these standards is proposed. This thesis has two aims. Primarily, to develop an approach for evaluation of business process modeling standards, and as a secondary aim, to apply this evaluation model onto a set of selected standards for business process modeling and thus perform a comparison of these standards. The evaluation model has two main components. The first part is to create a set of characteristics which represent two existing points of view onto the exploitability business process modeling (e.g. during the development of IS/ICT and during BPR/BPM1). During the identification of particular characteristics, a research into the related literature and other sources has been performed to provide a sufficient basis for this activity. The second part of the developed approach is to the application of PEMM (Process & Enterprise Maturity Model), which was developed by Dr. M. Hammer for the purpose os auditing the maturity of business processes. Both of these parts are then put together into one evaluation framework. Based on information gathered from the respective specifications of particular standards, related literature and articles, we've performed an application of this evaluation framework on three standards for business process modeling: EPC, BPMN and IDEF3. The benefits of this thesis could be seen as a creation of a very own approach for evaluation of business process modeling standards. Additionally by performing the comparison of these three standards for business process modeling we've created a guideline which could be there fore applied by the potential reader during the decision making of what standard to use for business process modeling (in the context of expected purpose of this modeling).

This thesis deals with process modeling respectively application specific modeling methodology developed by prof. Ing. Václav Řepa Csc. for the selected company active in manufacturing. The main objective and part of the thesis forms creation of process model. It's preceded by introductory description of the selected company and its global long-term goals set by management, SWOT analysis revealing strengths, weaknesses, opportunities and threats, on the basis of which is elaborated a strategy to exploit opportunities for the development of strengths. Before analyzing the processes and the design of process model Balanced Scorecard analysis is realized. Within its four perspectives, I propose and summarize the identified targets, along with their metrics, current and desired state. Further it's followed by process analysis and elaboration of process models to global (Eriksson-Penker model) and detailed (BPMN notation) level. Models have added the descriptive tables and description and main points of the design are summarized in the end. The main objective of work is followed by others, represented by the comparison of designed model and current situation in company, where is implemented quality management system ISO 9001:2000 (comparing similarities and differences, problems of quality system, etc.) and assessment of enviromental maturity of the company and its functioning from process perspective, using the knowledge model Michael Hammer PEMM (Process & Enterprise Maturity Model). Information obtained from the analysis and designs are put into context with each other to ensure consistency of whole design and my thesis and summarized in Chapter Conclusion.

Dopad procesní a datové integrace na efektivitu reportingu / Impact of the process and data integration on reporting efficiency

Sys, Bohuslav January 2013 (has links)
Nowadays, when the difference between failure and success is amount of the available information combined with exponential growth of the available information on web leads to rising need to track the quality of the data. This worldwide trend is not only global, but it affects even individuals and companies in particular. In comparison with the past these companies produce higher amount of data, which are more complex at the same time, all to get a better idea about the real world. This leads us to the main problem, when we not only need to gather the data, but we have to present them in such way, so they can serve the purpose for which they have been gathered. Therefore the purpose of this thesis is to focus on processes following the data gathering -- data quality and transformation processes. In the first part of the thesis we will define a basic concept and issues, followed by methods necessary for acquiring requested data in expected quality, which includes the required infrastructure. In the second part of the thesis we will define real-life example and use the knowledge from previous part to design usable solution and deploy it into use. In conclusion we will evaluate the design compared to the result acquired from its real-life utilization.
