The software community of the 1980s was abuzz with seemingly endless approaches to producing higher-quality software. At the forefront was software metrics and its corresponding techniques, tools, and process-improvement schemes. Cyclomatic complexity, Halstead metrics, source lines of code (SLOC), Fagan inspection, defect counting, number of defects prediction, reliability estimation and model...

Component-Based Software Development (CBSD) is becoming the trend for software development by using the existing component. The existing components may be black box in nature. There are many software complexity metrics proposed by various researchers which are based on the source code of the software. But these traditional metrics are not applicable for black box component because source code i...

While the need for software metrics to aid in the assessment of software complexity for both development and maintenance has been widely argued, little agreement has been reached on the appropriateness and value of any single metric. McCabe's cyclomatic complexity metric, a measure of the maximum number of linearly independent circuits in a program control graph has been widely used in research...

Cost of software maintenance is estimated based on the experience by some experts since the standard for objective measurement is not available currently. We proposed a metric for estimating maintenance effort in this paper. The metric is computed by applying the change impact analysis to source code. Through experiments, we confirmed that the proposed metric estimate the maintenance effort bet...

Among the software quality metrics, coupling and cohesion play an important role since they provide a clue about the structuring of the classes of the system. They are, therefore, computed at the level of the classes. However, when analyzing the architecture of a system, we are not only interested in the class level, but also in the higher levels of the system structure, for example the package...

This paper looks closely at each of the software metrics generated by the McCabe Object-Oriented ToolTM and its ability to convey timely information to developers. The metrics are examined for meaningfulness in terms of the scale assignable to the metric by the rules of measurement theory and the software dimension being measured. Recommendations are made as to the proper use of each metric and...

The automated prediction of qualitative attributes such as software complexity is a desirable software engineering goal. A potential technique is to use software metrics as quantitative predictors for these kinds of attributes. We describe a pattern classification method where a large collection of classifiers is presented with randomly selected subsets of software metrics describing modules fr...

in this paper, we propose a new definition of intuitionistic fuzzyquasi-metric and pseudo-metric spaces based on intuitionistic fuzzy points. weprove some properties of intuitionistic fuzzy quasi- metric and pseudo-metricspaces, and show that every intuitionistic fuzzy pseudo-metric space is intuitionisticfuzzy regular and intuitionistic fuzzy completely normal and henceintuitionistic fuzzy nor...
