摘要
UML是软件工程中一种最常用的建模方法。由于UML是半形式化的,许多人致力于将UML转换成形式化方法(如Petri网)的研究。转换之后,对于定性的非功能参数的确认和验证就会更方便。鉴于现实世界中大部分信息的不确定性,系统分析师们提出了模糊UML的概念。尝试将模糊UML活动图转换成Petri网,从而能实现形式化验证以及性能评估。
UML is known as one of the most common methods in software engineering.Since this language is semi formed,many researches and effort have been performed to transform this language in to formal methods including Petri nets.Thus,the operation of verification and validation of the qualitative and non functional parameters could be achieved with more ability.Since the majority of the real world information are uncertain,there fore fuzzy UML diagram has been extensively used by system analyzer.This paper is attempted to transform activity diagrams created in fuzzy UML into fuzzy Petri net.So that the verification and performance evaluation operation could be performed formally,rather than exact visual analysis.
