Abstract:

This paper proposes a scenario-based early reliability prediction model. The operation profile of scenarios is built based on the use case diagram. A  simple communication diagram is used to get the parameters of the model. This model is integrated seamlessly with UML diagrams, and is applicable early in the software development lifecycle. We demonstrate the application in a case study of an automated personnel access control system. Compared with theprevious early reliability models, this model is more simple and easier to be implemented.

Key words: early reliability model, scenario, UML
