The term maintenance, when accompanied to software, assumes a meaning profoundly different from the meaning it assumes in any other engineering discipline. In fact, many engineering disciplines intend maintenance as the process of keeping something in working order, in repair. The key concept is the deterioration of an engineering artifact due to the use and the passing of time; the aim of main...

Dr. Abdel-Moez Bayoumi is a professor of mechanical engineering and biomedical engineering and the Associate Dean of the College of Engineering and Computing at the University of South Carolina. The Center for Predictive Maintenance hosts a versatile facility for testing aircraft components and supports the adoption of the conditionbased maintenance (CBM) paradigm within the U.S. Army Aviation ...

1. MOTIVATION AND PROBLEM A feature can be defined as a prominent or distinctive user-visible aspect, quality or characteristic of a software system [5]. Feature mapping is one of the longest-standing problems in the broad spectrum of software engineering [1][2][3][4]. This activity is key to software maintenance as it consists of explicitly identifying all code elements responsible for realizi...

Software maintenance is responsible for approximately 80% of the total cost of software. In order to reduce maintenance costs by improving both software productivity and quality, several Software Engineering Environments have been built. In this paper, we present the main characteristics of the Adele system, showing how this system is able to take account of software maintenance problems. We co...

Prof. dr. ir. Tiedo Tinga is presently chairing the Dynamics based Maintenance group at the University of Twente and is also associate professor Maintenance Technology at the Netherlands Defence Academy. He is leading research programs at both institutes on predictive maintenance, reliability engineering and maintenance optimization. Prior to joining the universities, he has been working as a s...

A central problem in software maintenance is change propagation: given a set of primary changes that have been made to software, what additional secondary changes are needed? Although many approaches have been proposed, automated change propagation is still a significant technical challenge in software engineering. In this paper we report on an evaluation of an agent-based approach for change p...

A software maintenance methodology, The Software Service Bay, is introduced. This methodology is analogous to the automotive service bay which employs a number of experts for particular maintenance problems. Problems in maintenance are reformulated so they may be solved with current AI tools and technologies.

One of the most critical problems in software maintenance and evolution is propagating changes. Although many approaches have been proposed, automated change propagation is still a significant technical challenge in software engineering. In this paper we present an agent-oriented change propagation framework based on fixing inconsistencies when primary changes are made to design models. A core ...

A method for the prediction of software maintainability during software architecture design is presented. The method takes (1) the requirement specification, (2) the design of the architecture (3) expertise from software engineers and, possibly, (4) historical data as input and generates a prediction of the average effort for a maintenance task. Scenarios are used by the method to concretize th...
