UCM Scenarios Based Visual Modeling Research

Scenario-based modeling software requirement technology is proved to be one of the most effective and widely used modeling techniques in software requirements engineering.However, the vagueness and inconsistent issues of scenario modeling method affect its use results.The visual descriptions of scenarios can significantly reduce the ambiguity in software requirement descriptions.Based on the existing relationship between the level of abstraction scenario analysis and Use Case Maps,this paper researches the visualization description methods in software requirements.This paper analyzes the shortcomings of traditional use case modeling techniques and scenario modeling techniques.Firstly,this paper introduces the specific steps of the scenario visualization modeling technology based on UCM models.This method adopts use case technology to capture the requirement,then obtain scenario from use case models and uses the UCM models to describe the scenarios.Secondly, it uses the unified modeling language UML activity diagram to support and represent the UCM model, in order to address the usability issues of UCM model.Finally, through the case of mobile switch system,this paper illustrates the application of the scenario visualization modeling technology based on UCM models in requirement modeling process.This paper has theoretical and practical value in solve the usability problems of UCM models and the vagueness and inconsistent issues of scenario modeling method.
