EFFECTIVE DIAGRAMMATICAL SYSTEMS ANALYSISUSING THE INTERRELATIONSHIPSAMONG USE CASE DIAGRAMS, PETRI NETS AND IDEF0 DIAGRAMS

摘要

In the systems analysis, specifications are describedrnwith diagrammatical representations. Theserndiagrammatical representations are described byrninterviewing experts in the target system. Thernspecifications described with diagrammaticalrnrepresentations can be viewed as knowledge. In systemsrnanalysis and design, the diagrammatical representationrnwith one viewpoint may include some ambiguities.rnTherefore, it is necessary to perform systems analysis andrndesign by describing the several diagrammaticalrnrepresentations in two or more viewpoints. In this paper,rnwe provide an analysis process to obtain a well StructuredrnIDEF0 model. In our analysis process, in order to acquirernthe well-structured IDEF0, use case diagram and Petri netrnare used. The authors apply knowledge management tornthe analysis process. The diagrammatical representationsrnare described by knowledge representation. Therncomputer-aided tools have been implemented for semiautomaticrndiagrammatical transformation and systemsrnanalysis navigation. The entrance examinationrnmanagement system is analyzed as an example.
