Semantic discovery and reuse of business process patterns

Aldin, Laden January 2010 (has links)
In modern organisations business process modelling has become fundamental due to the increasing rate of organisational change. As a consequence, an organisation needs to continuously redesign its business processes on a regular basis. One major problem associated with the way business process modelling (BPM) is carried out today is the lack of explicit and systematic reuse of previously developed models. Enabling the reuse of previously modelled behaviour can have a beneficial impact on the quality and efficiency of the overall information systems development process and also improve the effectiveness of an organisation’s business processes. In related disciplines, like software engineering, patterns have emerged as a widely accepted architectural mechanism for reusing solutions. In business process modelling the use of patterns is quite limited apart from few sporadic attempts proposed by the literature. Thus, pattern-based BPM is not commonplace. Business process patterns should ideally be discovered from the empirical analysis of organisational processes. Empiricism is currently not the basis for the discovery of patterns for business process modelling and no systematic methodology for collecting and analysing process models of business organisations currently exists. The purpose of the presented research project is to develop a methodological framework for achieving reuse in BPM via the discovery and adoption of patterns. The framework is called Semantic Discovery and Reuse of Business Process Patterns (SDR). SDR provides a systematic method for identifying patterns among organisational data assets representing business behaviour. The framework adopts ontologies (i.e., formalised conceptual models of real-world domains) in order to facilitate such discovery. The research has also produced an ontology of business processes that provides the underlying semantic definitions of processes and their constituent parts. The use of ontologies to model business processes represents a novel approach and combines advances achieved by the Semantic Web and BPM communities. The methodological framework also relates to a new line of research in BPM on declarative business processes in which the models specify what should be done rather than how to ‘prescriptively’ do it. The research follows a design science method for designing and evaluating SDR. Evaluation is carried out using real world sources and reuse scenarios taken from both the financial and educational domains.

Simulação do fluxo de peças durante a operação de torneamento em sistemas flexíveis de fabricação baseado em framework orientado a objetos / Simulation of the flow of work pieces during the turning operation on flexible manufacturing systems based on object oriented framework

Flávio Henrique Fernandes Volpon 02 April 2012 (has links)
A análise e construção de um sistema computacional utilizando conceitos de frameworks, para simulação do fluxo de peças em Sistemas Flexíveis de Fabricação são apresentados. A criação da estrutura de dados para descrição completa do Sistema Flexível de Fabricação e a simulação da etapa de torneamento, durante o fluxo da peça são implementados. O método de simulação no framework é baseado na modelagem geométrica e funcional da placa de fixação durante a operação de torneamento. Para a escolha da melhor fixação durante o torneamento, é utilizado um índice calculado pelo sistema computacional, de acordo com a qualidade da fixação. No processo de desenvolvimento do framework são utilizados conceitos de Reuso de Software, associações entre Frameworks e uma estrutura de persistência de dados utilizando um banco de dados relacional, com um modelo de armazenamento desvinculado dos tipos de dados e tabelas especificas, permitindo assim implementações de novos métodos para simulação de outros meios produtivos. / Analysis and construction of a computer system using concepts of frameworks, for simulation of the workflow pieces in flexible manufacturing systems are presented. The creation of a database to fully describe the flexible manufacturing system and the simulation of the turning stage, during the workflow pieces are implemented. The method of simulation in the framework is based on geometric modeling and functional of the mounting plate during the turning operation. To choose the best mounting during the turning operation, its assigned an index calculated by the computer system, according to the quality of mounting. In the process of development of the framework were used concepts of software reuse, frameworks and associations between a structure of data persistence using relational database, with a detached storage model data types and specific tables, allowing implementation of new methods to simulate other productive means.

Effects Of Spl Domain Engineering On Testing Cost And Maintainability

Senbayrak, Ziya 01 February 2013 (has links) (PDF)
A software product line (SPL) consists of a set of software-intensive systems sharing a common, managed set of features that satisfy the specific needs of a particular market segment or mission and that are developed from a common set of core assets in a prescribed way. Together with testing of final deliverable products developed within the SPL, called Integration Testing, particularly important in this context is the way individual hardware as well as software components in an SPL are tested and certified for usage within the SPL. This study investigates specific approaches and techniques proposed in the literature for unit testing in the SPL context. Problems inherent to this issue were studied and possible solutions aiming towards systematic and effective testing of hardware as well as software units in SPLs have been proposed. The specific problems of SPL testing in ASELSAN were investigated in the light of these possible solutions and their applicability as well as their benefits were quantitatively assessed.

protoBOM : Framework that semi-automatically generates Decision Support Systems based on Software Product Lines

Gomez Lacruz, Maria January 2008 (has links)
This thesis presents the development of a prototype of the Baseline Oriented Modeling (BOM) approach, called protoBOM. BOM is a framework that semi-automatically generates Decision Support Systems in a specific domain, based on Software Product Lines. protoBOM semi-automatically generates applications as PRISMA architectural models by using Model-Driven Architecture and Software Product Line techniques. These models are automatically compiled and the object code (C#, in .NET) is generated obtaining an executable application. In protoBOM, the user constructs Decision Support Systems in a simpler way by using the ontologies of the diagnosis and the application domains by means of Domain Specific Languages. The interfaces will be closer to the problem domain, which will facilitate user interaction in a manner simple and intuitive.

Proposta de metodogia de engenharia de domínio para o desenvolvimento de sistemas de automação industrial

Kipper, Marcelo Mondadori January 2010 (has links)
Engenharia de domínio (do inglês: DE - Domain Engineering) é uma proposta surgida no âmbito da Engenharia de Software e que visa o aumento do reuso no desenvolvimento de sistemas, buscando uma redução dos custos e do tempo de desenvolvimento. A aplicação desta técnica em sistemas de automação industrial (produtos e plantas industriais) – os quais incluem múltiplas disciplinas (sistemas mecânicos, elétricos, pneumáticos, entre outros), diferentemente da engenharia de Software que trata basicamente do reuso de artefatos de Software – vem despertando o interesse de algumas instituições de pesquisa, como o IAS (Instituto de Automação Industrial e Engenharia de Software da Universidade de Stuttgart), e será abordada neste trabalho. A engenharia de plantas industriais é crescentemente realizada nas chamadas ferramentas de gerenciamento de ciclo de vida de plantas PLM (Plant ou "Production Lifecycle Management"), que se originou do conceito de "Product Lifecycle Management", cuja sigla também é PLM. A idéia destas ferramentas é o gerenciamento de ativos não somente durante o processo de engenharia, mas também durante a operação e manutenção até o descomissionamento das plantas. Muitas destas ferramentas PLM englobam o paradigma de orientação a objetos da Engenharia de Software, e baseadas neste paradigma, abordam a integração de dados entre os artefatos das várias disciplinas. Este trabalho apresenta o conceito de um artefato técnico reutilizável multidisciplinar, que foi a base para a elaboração de uma metodologia de engenharia de Domínio adaptada a ferramentas PLM, que se baseiam no paradigma de orientação a objetos. A metodologia proposta foi validada experimentalmente em um estudo de caso de uma Planta Modular de Produção (MPS – Modular Production System) em conjunto com a ferramenta PLM Comos da Siemens. Os resultados obtidos indicam a viabilidade da implementação da metodologia proposta em projetos na indústria, visando a redução de custo e tempo de desenvolvimento através do reuso de artefatos técnicos multidisciplinares em domínios com aplicações semelhantes. / Domain Engineering comes from the Software field and aims the increase of reuse to allow reduction of cost and time in the development of systems. The deployment of this methodology in automation systems (products and industrial plants) – in which more disciplines (mechanical, electrical, pneumatic, among others) are present and therefore differs from the Software engineering, that deals basically with the reuse of Software artifacts – has awakened the interest of some research institutes, like the IAS (Institute of Industrial Automation and Software Engineering of the University of Stuttgart), and will be analyzed during this work. The engineering of industrial plants is increasingly executed using the so called PLM Tools ("Plant or Production Lifecycle Management"), whose concept was originated from "Product Lifecycle Management", also abbreviated as PLM. The idea of these tools is to manage the assets not only in the engineering process, but also through operation and maintenance until the decommissioning of the industrial plants. Many of these PLM Tools support the object orientation principle from the Software engineering, and based upon this principle they address the integration of data from artifacts of the various disciplines. This work presents a concept for a multidisciplinary reusable technical artifact that was the base for the elaboration of an adapted DE Methodology for PLM Tools, in which the object oriented principle, is present. The presented ideas have been experimentally validated using as a case study a Modular Production System (MPS) together with the PLM Tool Comos from the company Siemens. The obtained results indicate a feasible implementation of the proposed methodology in the industry, aiming cost and time reduction through the reuse of multidisciplinary technical artifacts in domains with similar applications.
