Thesis (M.Eng.)--Chulalongkorn University, 2002

Due to the fact that aspect-oriented (AO) paradigm can solve the problem of crosscutting concerns in software development. And this kind of software cannot be solved properly by the object-oriented approach. Software requirements, which are the important artifacts in the development process, should be managed using a model for AO to fully support this paradigm at the later development stages. This thesis proposes a requirements model that extends the use-case driven approach. This model supports the unified process. It introduces a new parallel process to the requirements workflow of the unified process. This thesis presents a new requirements-level diagram called the Crosscutting Stack Model, including a set of notations for modeling the aspects that are extracted by the use-case purification and aspect extraction process. This thesis also presents a scenario descriptive diagram called the Object/Crosscutting/Use Case Maps, including a set of notations for use-case and aspect explanation in the aspects realization process. The modeling tool, named ASREM, is developed to support the CMS diagram. Teh modeling tool, named OCUM Vectra, is developed to support the OCUM diagram. Both modeling tools are developed as Rational Rose add-in.
