A Modeling Methodology for Automotive Embedded System¡GAn MDA Approach with UML

Lin, Chia-Chun 11 July 2012 (has links)
Automotive embedded systems used much in the main body control system. Also because the system needs to meet functional requirement, environment requirement, timing requirement, interface requirement and Failure Mode and Effects Analysis (FMEA) so it is necessary to have an automotive embedded systems modeling methodology. Therefore, this study proposes an automotive embedded systems modeling methodology which combines MDA and UML, and detailed description of the model diagram used by each modeling phase and the diagram modeling method and steps. System development team can be clearly implemented in accordance with the methods and steps for automotive embedded system modeling. The methodology also can be used as the communication standard of the system development team. Systems modeling during system modular can promote module reuse rate in order to enhance the efficiency of system development. The methodology of this study is based on design science research methods, usability evaluation of the modeling methodology is implemented for the modeling of demand for Parking aid control unit, the PIM modeling and code conversion. With prove the availability of this modeling methodology. From the results of the assessment system development team can be based on the methodology of modeling methods and procedures to express the results in line with the needs and systems analysis and design of automotive embedded systems and convert the system operating platform and code.

Specifying Class constraint and operation using Object Constraint Lanugage

Liu, Chi-liang 03 February 2006 (has links)
Today, modeling the software with unified modeling language (UML), model driven architecture (MDA) concept, and computer-aided software engineering (CASE) tool are the main trend for the objected-oriented systems analysis and design. Furthermore, to enhance the degree of transformation automation and design reuse in the system development process, object constraint language (OCL) is used in UML modeling to specify the navigation, constraint, operation specification, and so forth. However, the guideline for using OCL in class diagram specification and its transformation to JAVA code is lacking. This research presents an approach utilizing the OCL to specify the constraint and operation specification for the class diagram when modeling the platform independent model (PIM), which can then be transformed into the JAVA platform specific model (PSM) and code using a CASE tool. A real-world case using the integrated techniques is presented and a CASE tool is used to illustrate the concepts, application, and the advantages of using the proposed approach. With this approach, the system developer can transform PIM into PSM and code automatically and thereby enhance the efficiency of system development.

Modeling the User Interface of Web Application with UML For MDA Transformation

Jhan, Yin-Yun 21 June 2006 (has links)
This study presents a systematic methodology which integrated the model driven architecture with object-oriented technique to transform the user interface (UI) platform independent model (PIM) into Web-based UI platform specific model (PSM), and then into code model. A real-world case using the integrated techniques is presented and the Rational Rose is used to illustrate the concepts, application, and the advantages of using the proposed methodology. With this approach, the system developer can transform UI PIM into Web-based UI PSM and code automatically and thereby enhance the efficiency of system development.

Specifying Design Patterns with Object Constraint Language

Hsieh, Kun-Ta 19 July 2007 (has links)
Today, unified modeling language (UML) has become a standard modeling language in object-oriented systems analysis and design. Over the past few years a considerable effort has been made in synthesizing UML, MDA (model driven architecture), design patterns and CASE tool to increase the productivity of the system development. Specifying the design patterns with object constraint language (OCL) has become a main trend in this area. This study classifies the OCL expressions and design patterns and presents a method to specify each design pattern with the OCL and UML when modeling the platform independent model which can then be transformed into the platform dependent model, and to a code model. A real-world case using the integrated techniques is presented and a CASE tool is used to illustrate the concepts, application, and the advantages of using the proposed approach. With this approach, the system developer can transform PIM into code automatically and thereby enhance the efficiency and reusability of system development.

Modeliavimu grindžiamas J2EE platformos trijų sluoksnių informacinių sistemų kūrimas / Model-driven development of 3-tier JEE platform applications

Mikuckas, Modestas 20 June 2012 (has links)
Viena iš technologinių sričių, kur galima pritaikyti modeliavimu grindžiamą architektūrą (MGA) yra Java Enterprise Edition (J2EE) informacinių sistemų kūrimas. Nors generuoti pilną programinį kodą taikant MGA metodus nėra įprasta, tačiau egzistuoja abstraktūs metodai, bei daliniai sprendimai leidžiantys daryti prielaidą, kad tai yra įmanoma. Remiantis egzistuojančiais abstrakčiais metodais ir daliniais sprendimais buvo sukurtas MGA metodas ir kodo generatorius, leidžiantis sugeneruoti visą programinį kodą pagal modelio duomenis. Sukurtas metodas buvo išbandytas su realia informacine MagicTest žinių testavimo sistema. Bandymas su realia sistema parodė, kad pasiūlytas MGA metodas gali būti sėkmingai taikomas JEE platformos informacinių sistemų kūrimui. / One of the technological areas where can be used model driven architecture (MDA) is Java Enterprise Edition (J2EE) development of information systems. Although to generate a complete program using MDA is not common, but there are some abstract methods, and partial solutions suggesting that this is possible. Based on existing methods of abstract and partial solutions new MDA method and code generator was created. Generator allows to generate software code based on the model data. The method and generator was tested with the real information MagicTest knowledge testing system. The test of the real system showed that the proposed MDA method can be successfully applied to J2EE platform for developing information systems.

Transformation of UML Activity Diagrams into Business Process Execution Language

Mustafa, Nasser Mousa Faleh 19 July 2011 (has links)
Researchers in software engineering proposed design method for distributed applications to construct a set of communicating system components from a global behavior. The joint behaviors of these components must precisely satisfy the specified global behavior. The next concern is to transform the constructed models of these components into executable business processes by ensuring the exchange of asynchronous messages among the generated business processes. The introduction of Service-Oriented Architecture (SOA) has helped to achieve this goal. SOA provides high flexibility in composing loosely-integrated services that can be used among business domains to carry out business transactions; this composition is known as service orchestration. Moreover, SOA supports Model Driven Architecture (MDA) such that services modeled as UML Activity Diagrams (AD) can be transformed into a set of Business Execution Language (BPEL) processes. Many researchers discussed the transformation of UML AD and the Business Process Modeling Notation (BPMN) into BPEL. However, they did not discuss the practical limitations that some of these transformations impose. This thesis addresses the imitations of the transformation from UML AD to BPEL processes using the IBM Rational Software Architect (RSA). We showed here that the tool is unable to create the correct BPEL artifacts from UML AD components in certain cases, for instance when the behavior includes the alternative for receiving single or concurrent messages, a weak loop, or certain choice activities. Furthermore, we provided novel solutions to the transformations in these cases in order to facilitate the transformation from UML AD to BPEL.

In addition the higher level of abstraction that this adaptive library is having will give a speed up in developing the application and higher quality solution because of the maintainability and reusability.
