proper decisions play a crucial role in any software architecture design process. an important decision of design stage is the selection of a suitable software architecture style. lack of investigation on the quantitative impact of architecture styles on software quality attributes is the main problem in using such styles. consequently, the use of architecture styles in designing is based on th...

Maintainability is an important quality attribute for almost every quality model. Maintainability of the software is considered as most expensive phase in software development life cycle as it consumes almost major part of the total effort allocated to the software system. Maintainability evaluation is complex due to its imprecise output. This paper proposes a maintainability model by consideri...

The maintainability aspect of some complex products has a significant role during the life cycle; it is the design attribute determining the performance of various maintenance activities such as: inspection, diagnosis, repair, and replacement. If a product has poor maintainability, the maintenance activities which have to be performed on it during its life cycle are difficult, increasing the co...

This paper presents ongoing work on using data mining clustering to support the evaluation of software systems’ maintainability. As input for our analysis we employ software measurement data extracted from Java source code. We propose a two-steps clustering process which facilitates the assessment of a system’s maintainability at first, and subsequently an in-cluster analysis in order to study ...

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...

Software architecture evaluation methods aim at identifying potential maintainability problems for a given architecture. Several of these methods exist, which typically prescribe the structure of the evaluation process. Often left implicit, however, are the concrete system attributes that need to be studied in order to assess the maintainability of implemented architectures. To determine this s...

Maintainability is an internal quality characteristic that is contemplated by many users and developers, and therefore is deeply related to software architecture. It presents an organization of its components and relation which promote or obstruct different attributes like testability, changeability, and analyzability. As part of a research in progress, this article analyzes and organizes a set...

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...
