This paper presents a classification of indicators the maintainability technical systems according to their economic characteristics. In study, all parameters are determined on basis probabilistic approaches assessing continuous random variables. It is also shown that quantitatively, can be assessed by laboriousness restoring operability device. And this, in turn, cost labor and funds for preve...

Maintainability is a measure of the ease with which a software system can be maintained. In this paper we propose a quantitative deenition of maintainability, and discuss means to estimate the maintainability of a software system on the basis of a static analysis of its deliverables. Such an estimation eeort is useful inasmuchas it allows us to predict the maintainability of a software system a...

Software maintainability is an important aspect for all software engineering paradigms. Considering the maintainability a factor influencing the software quality and reliability, the estimation can help to improve overall software quality. Maintainability is an indirect and derived measure which needs to predict using the other direct measures. Soft computing approaches have been used widely in...

Background: Despite the number of empirical studies that assess Aspect-Oriented Software Development (AOSD) techniques, more research is required to investigate, for example, how software maintainability is impacted when these techniques are employed. One way to minimize the effort and increase the reliability of results in further research is to systematize empirical studies in Aspect-Oriented...

Models are core artefacts in software development and maintenance. Consequently, quality of models, especially maintainability and extensibility, becomes a big concern for most non-trivial applications. For some reasons, software models usually contain some duplications. These duplications had better be detected and removed because the duplications may reduce maintainability, extensibility and ...

Software maintenance is a crucial phase of the software development life cycle. It is important to facilitate this stage, complying with both functional and non-functional requirements. However, very often the main focus is made on the functional features of the application, whereas fault tolerance mechanisms are neglected and as a result do not provide sufficient maintainability and reusabilit...

Context: Application of a refactoring operation creates a new set of dependency in the revised design as well as a new set of further refactoring candidates. In the studies of stepwise refactoring recommendation approaches, applying one refactoring at a time has been used, but is inefficient because the identification of the best candidate in each iteration of refactoring identification process...

Using model-to-model transformations to generate analysis models or code from architecture models is sought to promote compliance and reuse of components. The maintainability of transformations is influenced by various characteristics as with every programming language artifact. Code metrics are often used to estimate code maintainability. However, most of the established metrics do not apply t...
