An Improvement on C&K Object-Oriented Software Metrics Suite

Based on the study of object-oriented software measurement and the characteristics of object-oriented technology, some improvements on C&K metrics suite are discussed in this paper. Some new metrics for class size and class hierarchy measurement are presented including complexity per class, number of methods, depth of multi-inheritance tree and number of father etc. Meanwhile, the applications of these improved metrics in software engineering are discussed. All the improvements can supplement C&K metrics and optimize the result of measurement.
