  Abstract

This paper suggests a technique for program segmentation and maintenance using PSDG(Post-State Dependency Graph) that improves the quality of a software by identifying and detecting defects in already fixed source code. A program segmentation is performed by utilizing source code analysis which combines the measures of static, dynamic and semantic slicing when we need understandability of defect in programs for corrective maintenance. It provides users with a segmental principle to split a program by tracing state dependency of a source code with the graph, and clustering and highlighting. Through a modeling of the PSDG, elimination of ineffective program deadcode and generalization of related program segments are possible. Additionally, it can be correlated with other design models as STD(State Transition Diagram), also be used as design documents.
