Abstract:Considering the complex relationship between the various components of software components, not clear responsibilities, this paper introduces aspect-oriented programming technology and proposes a kind of reusable and hierarchical aspect-oriented software implementation framework—R-AoSAS (Real-time Aspect-oriented Software Architecture Style) for the facing of vending machine real-time system in software development. This framework can effectively separate functional components and non-functional components. In order to bind or combine functional components and non-functional components, this framework can call aspectual Join Point as their interface. When applying R-AoSAS to software development, we may use time-management model and task-scheduling model supplied by the core control layer of R-AoSAS, to meet non-functional requirements such as timing, task creation and task scheduling, thus improving quality and reusability of software. In order to validate the functions of R-AoSAS, this paper introduces this framework to the design of the money management system. This application of the system has fully reflected the prospect of application.

Abstract:Agent and Multi-Agent (MAS) system has gradually become mature, and has been widely used in system modeling, agile manufacturing, network monitoring and many other fields. In order to facilitate the development of MAS, a variety of Agent oriented infrastructure platform have been built, e.g. JADE which have been used widely.

Both diagrams are used as the input for the software reliability analysis method. This method utilizes a bottom-up way approach to evaluate the software reliability, which adapts to the evaluation of large scale systems with complex structures.
