| Summary: | Software development life cycle maintenance has been advocated as the critical
part that consumes more time and resources. To understand the magnitude of the
task to maintain the software product, software metrics have been used to make
quantification based on their respective software features. To predict software
maintainace, the proper metrics need to be selected to avoid the duplication or the
outlying of the potential metrics. This is because on one hand, the individual
metrics deals with only a single feature of the object-oriented systems, while on the
other hand; the suites either contain duplicate metrics of the same goal or lack
some important metrics that match the common attributes in the software products.
The latest effort to solve this selection problem is the development of the metrics
selection model that uses genetic algorithm (GA). However, the process failed to
state clearly the encoding strategy in its initial stage.
This thesis clarifies the issue using the objective method to develop the GA metric
selection model for predicting the maintainability of object-oriented systems. The
study proposes the use of software metric thresholds in the classification process
during the GA representation. The software metric thresholds were used as
indication for identifying unsafe design in software engineering. To evaluate this
technique, an experiment was conducted on two geospatial systems developed
using Java programming language where the Chidamber and Kemerer (CK)
metrics were used. The proposed technique was also compared to the ranking
results from the experts. The comparison results obtained when compared with
those of Principal Component Analysis and the complete software metric suite
were very promising. Moreover, the three techniques show significant differences
in both treatments when compared using analysis of variance. |
