Most research done to date on software maintenance has been focused mainly on the evolution of legacy systems based on obsolete technologies. However, the use of more recent yet evolving technologies, like component-based techniques, also raise various issues about software comprehension and evolution. In particular, current industrial-strength component models like COM are based on many techni...

Modern automotive control systems are incredibly intricate hybrids of software components and hardware mechanisms. Gaining a sufficient understanding of such a system in order to perform reliable maintenance with predictable results can be quite difficult. This paper discusses three specific challenges related to this task: (1) having tools that provide sufficiently robust analysis to support t...

This paper outlines a distinction between Distributed Truth Maintenance and Distributed Belief Revision. The latter has a more complex conceptualization than the former and it needs the evaluation of special features as the relationship between the Informant’s reliability and the Information’s credibility. We point out some criteria to judge the qualities of a Distributed Belief Revision strate...

maintenance is one of the systems which can play an essential role in the success of manufacturing and services systems. one of the most maintenance innovative approaches is agile maintenance. based on this approach, organizations integrate maintenance concepts with agility features such as: flexibility, agile and fast move, etc and also are trying to provide one hundred percent preparing equip...

Maintenance of component-based software platforms often has to face rapid evolution of software components. Component dependencies, conflicts, and package managers with dependency solving capabilities are the key ingredients of prevalent software maintenance technologies that have been proposed to keep software installations synchronized with evolving component repositories. We review state-of-...

In this paper we model knowledge dynamics in agents’ belief bases in a collaborative multiagent system. Four change operators are introduced: expansion, contraction, prioritized revision, and non-prioritized revision. For all of them, both constructive definitions and an axiomatic characterization by representation theorems are given. We formally justify minimal change, consistency maintenance,...

The fundamental knowledge container in case-based reasoning is the case base of prior experiences. An important focus of recent CBR research is on maintenance strategies for achieving compact, competent case bases, as a way to improve the performance of CBR systems. However, the actual tradeoos between competence, compactness, and performance may be complex. Consequently, this paper argues for ...

Aspect Oriented Programming (AOP) aims to ease maintenance and promote reuse of software components by separating core concerns from crosscutting concerns: aspects of a program that cannot be conned to a single program component. In AOP languages such as AspectJ, this kind of concern is encapsulated in an aspect and connected to main classes using pointcuts. This removes extraneous code from th...
