At present, most scholars know the important of requirements evolution, however, efficient methods to guide are still lacked. The paper presents the modeling of reflection requirement based on the ??-calculus to capture the requirements evolution, and makes it carry out efficiently and controllable. Aimed at the evolution issues of OWL-S requirements specification, this paper proposes a ??-Calculus...
The process of traditional requirements acquisition and analysis is generally completed by domain experts and requirements analysts, which will greatly restrict the requirements modeling automatization degree and userpsilas participation degree in the requirements process. This paper presents a reflective mechanism for evolution of requirements specifications (RMERS) that supports OWL-S. In the phase...
The traditional Architectural Description Languages ADLs lack the ability to describe the crosscutting concerns and crosscutting interactions in the software architecture, which result in the design of the system difficulty in comprehension, evolution and reuse. This paper proposes a new Aspect-Oriented ADL-AC2-ADL to provide a formal basis for representation of the tangling and scattering concerns...
Crosscutting behaviors and features of architectural units have always been a tricky issue in software architecture design. If not well treated, they may cause some unnecessary coupling among architectural units and hamper maintenance, evolution and reusability of software products. Appropriate modeling approaches and expressions contribute to the solution of these problems. This paper proposes an...
MGCP is a very important protocol in SG, and the quality of design of MGC has a critical impact on the performance of 3G core network, this paper studies the mechanism of MGCP, and proposes a design scheme of MGC, according to our analysis, we propose an implementation prototype of MGC
