Enhancing classic transformation languages to support multi-level modeling

As practical tools for disciplined multi-level modeling have begun to mature, the problem of supporting simple and efficient transformations to-and-from multi-level models to facilitate interoperability has assumed growing importance. The challenge is not only to support efficient transformations between multi-level models, but also between multi-level and two-level model content represented in traditional modeling infrastructures such as the UML and programming languages. Multi-level model content can already be accessed by traditional transformation languages such as ATL and QVT, but in a way that is blind to the ontological classification information they contain. In this paper, we present an approach for making rule-based transformation languages "multi-level aware" so that the semantics of ontological classification as well as linguistic classification can be exploited when writing transformations.

Design and Implementation of Object-Oriented Teaching Aid System Based on UML Language

According to the characteristics of teaching materials diversity and intuitive man-machine communication, the object-oriented teaching aid system based on UML language is designed. Firstly, the principle of UML language is introduced, then the functions of this aid system are described, that is, student information management, operational subjects management, courseware management and system management, etc. On this basis, the system design is analyzed and described from the aspects of design process, application course, data structure and data sheet maintenance, focusing on the refining design of the system, pointing out that this system data can realize the management on the information about students, assessment, courseware and users. Finally the application process of the system is described, which can facilitate the teaching task.

Approaching the feasibility of SBVR as modeling language for ontology development: An exploratory experiment

Ontology development techniques still constitute an open research area despite its importance in semantic aware information systems. Until now, most methods have used UML in supporting ontology development process. Recent works propose the mapping of business rules expressions to ontology statements as a building technique by means of SBVR language. However, there is still no experimental research comparing such approaches.Aim of this work is to evaluate the feasibility of mapping business domain expressions to ontology statements. An exploratory experiment comparing performance of techniques based on UML and SBVR languages is presented. Comparison is rooted in the quality assessment of the ontologies developed by 10 equally sized groups randomly conformed by 30 undergraduate engineering students and applying such techniques.Developed ontologies largely outperform the minimally acceptable quality, according to the considered quality assessment framework. There is no statistical significant difference between the quality scores of the ontologies developed by means of UML and SBVR techniques, in any of the assessed quality dimensions.The feasibility of mapping business domain expressions to ontology statements is shown: ontologies developed by means of a SBVR based approach at least equate the quality of ontologies developed by using an UML based method. Results confirm previous research about the effectiveness of UML approaches for conceptualizing lightweight ontologies while stressing the potential of the SBVR language to express complex notions of a domain of interest. The potential of SBVR to OWL 2 mappings as an ontology development technique worthy of further study is highlighted.

Developing Integrated Performance Measurement System using Component Based Approach

In an industrial context defined by more acute competition, performance measurement becomes a control tool. The Business Intelligence module of Manufacturing Execution System (MES) software achieves Performances analysis function. However, the implementation of performance indicators in information system is a difficult problem. Indeed, the enterprises need methods to specify and to install their Performance Measurement System (PMS). In this paper, we propose a methodology of performance indicators implementation. We use the UML language to develop PMS model and Component Based Programming for its implementation. This method facilitates Performances Measurement System design and implementation.

Collaborative System Model for Dynamic Planning of Supply Chain

The business need to be structured as an integrated supply chain pushes companies to make use of a greater level of co-operation and coordination. As a means of coordination, negotiation has been chosen in this work. The object of this paper is to present formalism for negotiation in dynamic planning of a supply chain with the objective of maximizing the overall profit of each partner. To model the SC, we use the multi agent approach. Each enterprise is represented by its negotiator agent. The negotiations are formalized using UML language. The proposed negotiation process allows agents to develop a feasible production schedule.

Extensión del Diagrama de Secuencias UML para el Modelado orientado a Aspectos

The objective of this paper is to review the unified modeling language UML sequence diagrams, presenting STAIRS as an alternative way of formalizing UML interaction diagrams, especially sequence diagrams. STAIRS is a formal language for modeling interactive UML diagrams, especially sequence diagrams. The inherent problems of ambiguity that UML models have, including the production of models that are not necessarily corrected, are analyzed. It is demonstrated that STAIRS contributes to reducing this ambiguity. It is concluded that although there are new approaches for software development, such as aspect-oriented development, UML is capable of adapting to these developments. The review and analysis presented in this article could be especially useful for clarifying these aspects.

System level modeling methodology of NoC design from UML-MARTE to VHDL

The evolution of the semiconductor technology caters for the increase in the System-on-Chip (SoC) complexity. In particular, this complexity appears in the communication infrastructures like the Network-on-Chips (NoCs). However many complex SoCs are becoming increasingly hard to manage. In fact, the design space, which represents all the concepts that need to be explored during the SoC design, is becoming dramatically large and difficult to explore. In addition, the manipulation of SoCs at low levels, like the Register Transfer Level (RTL), is based on manual approaches. This has resulted in the increase of both time-to-market and the development costs. Thus, there is a need for developing some automated high level modeling environments for computer aided design in order to handle the design complexity and meet tight time-to-market requirements. The extension of the UML language called UML profile for MARTE (Modeling and Analysis of Real-Time and Embedded systems) allows the modeling of repetitive structures such as the NoC topologies which are based on specific concepts. This paper presents a new methodology for modeling concepts of NoC-based architectures, especially the modeling of topology of the interconnections with the help of the repetitive structure modeling (RSM) package of MARTE profile. This work deals with the ways of improving the effectiveness of the MARTE standard by clarifying and extending some notations in order to model complex NoC topologies. Our contribution includes a description of how these concepts may be mapped into VHDL. The generated code has been successfully evaluated and validated for several NoC topologies.

This survey proposes Knowledge-Based MDA method which realizes MDA methodology and appends it with Knowledge-based validation of CIM model has been proposed in the article. This validation is performed against the formal criteria that are described in Enterprise meta-model (formal structure that defines how an organization should work in ideal case). Applications created using this method could ensure the provided functionality highly conforms to user needs. The proposed method will be realized by using the following technologies: modeling languages UML and SysML, Object Oriented programming languages (C#), Relational Database (SQL Server) and XML (XMI) as data transferring standard.DOI: http://dx.doi.org/10.5755/j01.eee.120.4.1192

Brainstorming 2.0: Toward collaborative tool based on social networks

Social networks are part of Web 2.0 collaborative tools that have a major impact in enriching the sharing and communication enabling a maximum of collaboration and innovation globally between web users. It is in this context that this article is positioned to be part of a series of scientific research conducted by our research team and that mixes social networks and collaborative decision making on the net. It aims to provide a new tool open source for solving various social problems posed by users in a collaborative 2.0 based on the technique for generating ideas, brainstorming method and social networks together for the maximum possible adequate profiles to the virtual brainstorming session. A tool is run by a user called expert accompanied by a number of users called validators to drive the process of extracting ideas to the loan of various users of the net. It offers then the solution to the problem of sending a satisfaction questionnaire administered by an expert ready for the affected user to measure the level of his satisfaction and also the success of the process launched. For its implementation, we propose a unified modeling using UML language, followed by a realization using the JAVA language.

Requirements management within a full model‐based engineering approach

AbstractIn this paper we show how the Property‐Based Requirements (PBR) theory can be used to fully integrate Requirements Engineering (RE) into a Model‐Based Systems Engineering (MBSE) method using OMG UML and its SysML profile. The objective is to avoid “in‐parallel” management of two distinct expressions of the same specification (or design): once in a set of textual requirements and once in a model, which must be maintained to be consistent. This is achieved by the identification, in common modeling concepts, of Requirement Tracker Artifacts (RTA) that match the pattern defined by the Property‐Based Requirement theory. An illustration is provided with both the UML and SysML modeling language. We also outline how relationships defined “by construction” in the model can be exploited to carry out requirements management activities without addition of dedicated and redundant data. © 2011 Wiley Periodicals, Inc.

UML-Based Two-Way Referral MIS Requirement Analysis

China’s community health services starts in 1997 and becomes the most important part of the urban health services system with the development of China’s social security system and community security. Two-way referral system in China came into being with the further development of community medical services. This paper studies the construction of two-way referral management information system based on the social security system platform using information management system and UML language based on the survey of the present implementation of two-way referral system. The two-way referral management information system includes the feasible analysis, the analysis of functional requirement, the on-stream analysis of two-way referral process, the on-stream analysis of two-way referral management information system, the design of functional configuration and functional module. The paper aims to reduce the cost of two-way referral and increase the visiting rate and medical care of community health service organization.

Variability in UML language and semantics

Practitioners, who use UML as a sketching language are generally not too concerned about the precision of their models, but developers who build UML models to rigorously analyze software properties (e.g., to analyze the consistency of design constraints) or that can be mechanically transformed to implementations requiring tools and tool chains that are based on a precisely defined UML semantics (see this issue’s Expert Voice by Manfred Broy and Maria Victoria Cengarle as well as the regular paper on the many semantics of sequence diagrams by Zoltan Micskei and Helene Waeselynck). This needmotivatesmuchof thework ondefining appropriate formal semantics for the UML. There is a significantly large body of work on formalizing the UML—both syntactical appearance, internal representation and semantics (in terms of meaning), and the collective experience suggests that defining appropriate semantics for the UML has both a technical and a strong political/social aspect. This non-technical aspect is concerned primarilywith determiningwhat constitutes an “appropriate” language. The problem is that different stakeholders, including UML modelers fromdifferent domains, tool vendorswith specific ready to use solutions, have varying views of what constitutes an appropriate UML language and its semantics. It is not easily possible to support these sometimes competing views in a single language. This led to the view of UML as a “family of languages” and to the introduction of profile mechanisms and “semantic variation points” that can be used for specializing the syntax and semantics of UML.

Using the knowledge configuration model to manage knowledge in configuration for upstream phases of the design process

In this paper, we focus on industrial problem-solving in design and simulation processes, especially in the automotive and aerospace fields. In these fields, engineers handle a large range of expert models such as computed aided design (CAD) and computed aided engineering (CAE) models which encapsulate parameters and design rules, which are considered as knowledge. This knowledge has to be shared by different users and must remain coherent through the design and simulation activities. This means maintaining consistent parameter values, following design rules, etc.) during product development and especially in the early design stages. Nowadays, faced with the diversity and the increasing number of expert models used at the same time, there is a lack of parameters and design-rule management to keep the knowledge contained within them coherent throughout several design activities. To improve expert model inter-operability there are numerous product models (in UML language) which support the product lifecycle management approach through data and information management throughout the entire product lifecycle. However, these models are not focused on the management of knowledge embedded in CAD and CAE models. In this context we propose a model called the KCModel in UML, to manage the knowledge encapsulated and ensure the coherence, e.g. the same parameter value used in several expert models, through several product design activities in a collaborative engineering context. The KCModel is based on the MDA/MDE (model driven architecture/model driven engineering) approach to managing knowledge in configurations synchronized with CAD and CAE models. This research work and the KCModel come within the scope of a French national project called ADN: “Alliance des Donnees Numeriques” led by the company DPS (specialized in digital product simulation) with the participation of the following companies, amongst others: PSA-Peugeot Citroen, EADS and FAURECIA.

Modelling a maintenance management framework based on PAS 55 standard

This article shows the process of modelling a reference maintenance management framework (MMF) that represents the general requirements of the asset management specification PAS 55. The modelled MMF is expressed using the standardized and publicly available Business Process Modelling (BPM) languages UML 2.1 (Unified Modelling Language) and BPMN 1.0 (BPM Notation). The features of these notations allow to easily integrate the modelled processes into the general information system of an organization and to create a flexible structure that can be quickly and even automatically adapted to new necessities. This article presents a brief review about the usage of UML in maintenance projects, general characteristics of PAS 55, modelling concepts and their applications in the project of modelling the MMF. The arguments underlying the methodology and the choice of UML and BPMN are exposed. The general architecture of the suggested MMF is described and modelled through diagrams elucidating the general operation of PAS 55. From this development is appreciated the operation structure of a software tool that can incorporate MIMOSA standards and that can be made suitable for e‐maintenance functions, as an alternative to the commercial systems. Finally, some conclusions about the modelled framework are presented. Copyright © 2010 John Wiley & Sons, Ltd.

Integrating Textual and Graphical Modelling Languages

Graphical diagrams are the main modelling constructs offered by the popular modelling language UML. Because textual representations of models also have their benefits, we investigated the integration of textual and graphical modelling languages, by comparing two approaches. One approach uses grammarware and the other uses modelware. As a case study, we implemented two versions of a textual alternative for Activity Diagrams, which is an example of a surface language. This paper describes our surface language, the two approaches, and the two implementations that follow these approaches.
