A Method for Developing Model to Text Transformations

In the field of business process development, model transformations play a key role, for example for moving from business process models to either code or inputs for simulation systems, as well as to convert models expressed with notation A into equivalent models expressed with notation B. In the literature, many cases of useful transformations of business process models can be found. However, in general each transformation has been developed in an ad-hoc fashion, at a quite low-level, and its quality is often neglected. To ensure the quality of the transformations is important to apply to them all the well-known software engineering principles and practices, from the requirements definition to the testing activities. For this reason, we propose a method, MeDMoT, for developing non-trivial Model to Text Transformations, which prescribes how to: (1) capture and specify the transformation requirements; (2) design the transformation, (3) implement the transformation and (4) test the transformation. The method has been applied in several case studies, including a transformation of UML business processes into inputs for an agent-based simulator

Problem Frame Analysis of Weapon System of Systems Requirement

AbstractThe requirement of weapon system of systems(WSoS) plays a very important role in the development of WSoS,which is the basis of the design of WSoS and runs through the research of WSoS. Based on the requirement engineering method of problem frame, the problem frame of WSoS requirement(WSoSR) is built which is consisted of requirement, mission domain, task domain, operation domain and system of systems(SoS) domain. The phenomena between the domains is defined and the constraint set is given. The model of the WSoSR problem transformation is put forward including the transformation process and the transformation content. An example of combined firing employment to the enemy ship fleet is shown in the end

Lightweight Executability Analysis of Graph Transformation Rules

Proceedings of: IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC 2010). Leganés-Madrid, Spain 21-25 Septemeber 2010.Domain Specific Visual Languages (DSVLs) play a cornerstone role in Model-Driven Engineering (MDE), where (domain specific) models are used to automate the production of the final application. Graph Transformation is a formal, visual, rule-based technique, which is increasingly used in MDE to express in-place model transformations like refactorings, animations and simulations. However, there is currently a lack of methods able to perform static analysis of rules, taking into account the DSVL meta-model integrity constraints. In this paper we propose a lightweight, efficient technique that performs static analysis of the weak executability of rules. The method determines if there is some scenario in which the rule can be safely applied, without breaking the meta-model constraints. If no such scenario exists, the method returns meaningful feedback that helps repairing the detected inconsistencies.Work funded by the Spanish Ministry of Science and Innovation through mobility grants JC2009-00015 and PR2009-0019, projects TIN2008-02081 and TIN2008-00444 and the R&D programme of the Madrid Community, project S2009/TIC-1650.Publicad

Model-based enterprise framework for aerospace manufacturing engineering

In the context of aerospace digital transformation, gaining and maintaining competitive advantage has led aerospace manufacturers to change how product definition is communicated. Model-Based Definition (MBD) and Enterprise (MBE) are the next generations of product definition that aim to move from 2D drawings to a full 3D digital model. Even though traditional engineering drawings still play an essential role in product development, developing an MBE today, for an aerospace company, deals primarily with its fundamentals: how significant benefits are? This work focuses on defining the MBE value stream framework and evaluating the potential improvements that can be realised for MBE within an aerospace manufacturing engineering (ME) context. To achieve this aim, a methodological triangulation has been adopted through the framework. Based on a ME business case and value stream case study, findings suggest a significant reduction of manufacturing lead-time and cost as well as an improved quality of both the product and the process, resulting in less rework. The developed framework and analysis method have been successfully applied and validated to two different aerospace ME processes. Based on a data-driven approach, it proposes a reliable evaluation of potential improvements for MBE. Successful implementation of the MBE concept relies on maximising its potential benefits. Hence, this industrial research project and its key findings contribute to the development of a strategy for implementing MBE within the aerospace manufacturing company to enable a lean and efficient consumption of product definition

MDA-based ATL transformation to generate MVC 2 web models

Development and maintenance of Web application is still a complex and error-prone process. We need integrated techniques and tool support for automated generation of Web systems and a ready prescription for easy maintenance. The MDA approach proposes an architecture taking into account the development and maintenance of large and complex software. In this paper, we apply MDA approach for generating PSM from UML design to MVC 2Web implementation. That is why we have developed two meta-models handling UML class diagrams and MVC 2 Web applications, then we have to set up transformation rules. These last are expressed in ATL language. To specify the transformation rules (especially CRUD methods) we used a UML profiles. To clearly illustrate the result generated by this transformation, we converted the XMI file generated in an EMF (Eclipse Modeling Framework) model.Comment: International Journal of Computer Science & Information Technology-201

A constitutive model for analyzing martensite formation in austenitic steels deforming at high strain rates

This study presents a constitutive model for steels exhibiting SIMT, based on previous seminal works, and the corresponding methodology to estimate their parameters. The model includes temperature effects in the phase transformation kinetics, and in the softening of each solid phase through the use of a homogenization technique. The model was validated with experimental results of dynamic tensile tests on AISI 304 sheet steel specimens, and their predictions correlate well with the experimental evidence in terms of macroscopic stress–strain curves and martensite volume fraction formed at high strain rates. The work shows the value of considering temperature effects in the modeling of metastable austenitic steels submitted to impact conditions. Regarding most of the works reported in the literature on SIMT, modeling of the martensitic transformation at high strain rates is the distinctive feature of the present paper.The researchers of the University Carlos III of Madrid are indebted to the Comunidad Autónoma de Madrid (Project CCG10-UC3M/DPI-5596)) and to the Ministerio de Ciencia e Innovación de España (Project DPI/2008-06408) for the financial support received which allowed conducting part of this work. The authors express their thanks to Mr. Philippe and Mr. Tobisch from the company Zwick for the facilities provided to perform the tensile tests at high strain rates

Incorporating Security Behaviour into Business Models Using a Model Driven Approach

There has, in recent years, been growing interest in Model Driven Engineering (MDE), in which models are the primary design artifacts and transformations are applied to these models to generate refinements leading to usable implementations over specific platforms. There is also interest in factoring out a number of non-functional aspects, such as security, to provide reusable solutions applicable to a number of different applications. This paper brings these two approaches together, investigating, in particular, the way behaviour from the different sources can be combined and integrated into a single design model. Doing so involves transformations that weave together the constraints from the various aspects and are, as a result, more complex to specify than the linear pipelines of transformations used in most MDE work to date. The approach taken here involves using an aspect model as a template for refining particular patterns in the business model, and the transformations are expressed as graph rewriting rules for both static and behaviour elements of the models
