The maintainability of software systems is a crucial point in the software lifecycle. However, assessing the quality of the software’s architecture with respect to evolution is a challenging task. The evaluation of the maintainability of a system’s architecture is often made using scenario-based techniques. These techniques require a comprehensive anticipation of future adaptations of the syste...

The lifetime of a product is dependent on its maintainability. It is proved that a lot of cost spent towards maintainability. Researchers find it as a difficult task to measure and improve software maintainability. Here we proposed a risk based approach to improve software maintainability. Risk based approach accounts the probability of failure of a portion of code as determined by its complexi...

The software maintainability can be ensured by carefully control of its software development process. An early measurement of maintainability starting from design phase is always desirable to produce maintainable software. Some of the researchers have tried to use soft computing techniques to measure maintainability. In spite of their reported validations, these models are not calibrated and no...

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...

Nowadays, the products/systems project has demanded the inclusion of maintainability characteristics in order to facilitate support activities, and, so, to reduce the time of intervention used for repair, life cycle cost, and improvement of availability and operational regularity. This work develops a scale evaluation model of the maintainability indexes, using value functions acquired with the...
