This article presents an experience report on using MERODE as the business modeling method for the development of a web application. MERODE has several advantages as improving the flexibility and maintainability of applications and the possibility of doing automated verification and validation on the internal consistency of the model. The application's main functionalities were managing the org...

Electroplating Industries are deploying various waste treatment methods, for reducing the waste discharge to the environment as well as for reuse of waste metals and oxides. Use of different methods of waste treatment and reducing the waste discharge, requires due consideration of various abilities – performance, reliability, environment ability, stability, maintainability, quality, etc. called...

Over the past years it has become evident that an evaluation system was necessary for the European Research and Competitive funded projects which are large and complex structures needing constant monitoring. This is especially so for e-Health projects. The race to complete assignments means that this area is usually neglected. A proposed framework for the evaluation of R & D project systems usi...

With the industrial products competition, reliability, maintainability and safety are key characteristics for availability improvement. This is mainly true in industries like automotive, aeronautic, or NC machines tools. Therefore, it is crucial to predict these characteristics as soon as possible before the manufacturing starts. This paper presents an approach to provide indicators for maintai...

This contribution presents a new approach, based on Fuzzy Prototypical Knowledge Discovery, to predict the maintainability of class diagrams done using the Unified Modelling Language (UML), which has great importance on the final quality of object-oriented information systems (OOIS). The prediction model is built from metrics values obtained at the early phases of OOIS life-cycle. We will start...

Families of applications are steadily emerging for distinct settings such as embedded systems, navigational systems, financial applications or even web applications. This moves the attention from single application development to Software Product Line (SPL) development where the focus is on constructing reusable artefacts of the assembly line from which final products are obtained. This paper p...

Estimating the risk of in-sourcing is key to the success of the project, but often the risks are hidden in the software being in-sourced. In this thesis I will explore, using measures on the source code, to evaluate the maintainability state of a project, by applying a proposed Maintainability Model. The model defines measures for each maintainability characteristic of ISO 9126, and grades them...

This paper proposes a model of successful maintenance that can represent how maintainability of each software module changes as it ages. We found that some of the metrics, measured from 20 years old system, fit our model; i.e., values of those metrics seem to be proportional to the degree of maintainability. We described each metric’s critical line – a value that can be used for deciding whethe...

Although the belief of utilizing design patterns to create better quality software is fairly widespread, there is relatively little research objectively indicating that their usage is indeed beneficial. In this paper we try to reveal the connection between design patterns and software maintainability. We analyzed more than 300 revisions of JHotDraw, a Java GUI framework whose design relies heav...

The usability of user interfaces is crucial for the success of an application. Model driven user interface (UI) development speeds up the production of UIs and improves the maintainability of UIs. However, the usability evaluation of UIs is usually conducted by end-users or experts after UIs are generated. Such a user centric evaluation is usually time consuming and expensive, especially when t...
