Abstract: System analysis and modeling method based on lifecycle and various attributes of object is proposed in order to support system development and reuse. This method is intended to comprehend the life cycle of an object by grasping object information as an aggregate of information for an object's attribute and by integrating a state transition for each object's attributes. In this paper, we define (1) state, (2) attribute, (3) occurrence and merging of information and substance, propose an analysis method by Extended State Transitions Diagram (STD) (Lifecycle STD/Attribute STD/Attribute Integrated STD), and describe the results of its application for wholesale as an example.

Keywords: system analysis, extended state transitions diagram, lifecycle, attribute
