Code smells are indicators of software design shortcomings that can decrease software maintainability. An advantage of code smells over traditional software measures is that the former are associated with an explicit set of refactoring strategies to improve the existing design. As such, code smell analysis is a promising approach to address both the assessment and the improvement of maintainabi...

According to IEEE Standard Glossary of Software Engineering Terminology: maintainability is the ease with which a software system or component can be modified to correct faults, improve performance or other attributes, or adapt to a changed environment. [1]. Maintainability can also be defined as the probability that a specified maintenance action on a specified item can be successfully perform...

One of the main cost of maintenance is continual retesting. Testing will be characterized as the construction of pathways that reach from inputs to some interesting zone of a program. This zone could be a bug or a desired feature. In this reachability view, the goal of testing is to show that a test set uncovers no bugs while reaching all desired features. A system is hard to maintain if it is ...

In this position paper, we describe the research we have just initiated. We will investigate how the “maintainability” of a piece of software changes as time passes and it is being maintained by performing measurements on industrial systems. We present the notion of “maintainability”, our hypotheses, and our approach.

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...

A large number of software products enter the maintenance phase due to the growing application of information systems. Software maintenance is the modification of a software product after delivery to correct faults and improve its overall performance and quality. Easily maintainable software saves large costs and effort involved in developing the software. Hence maintainability assessment is an...

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...
