The Disaster Response Network Enabled Platform (DRNEP) is a system that integrates a set of independently developed infrastructure and disaster simulators. This paper describes some of the architectural choices that we made for DRNEP. The overall system uses a master-slave pattern, with one master simulator orchestrating all of the others, based on a central system clock. As the various simulators...
Tables are an important tool used by business analysts engaged in early requirements activities (in fact it is safe to say that tables appeal to many other types of user, in a variety of activities and domains). Business analysts typically use the tables provided by office tools. These tables offer great flexibility, but no underlying model, and hence no consistency management, multiple views or other...
This paper focuses on adapting the Granular Theories to system modelling for design and development of a service-oriented system. It highlights how to integrate Granular Computing Structures, development philosophy, methodology and UML for modelling, organising and addressing systems through a case study of Emergency Assistance Service System (EAS). The proposed approach to building software development...
We present a new approach for mutation analysis of security policies test cases. We propose a metamodel that provides a generic representation of security policies access control models and define a set of mutation operators at this generic level. We use Kermeta to build the metamodel and implement the mutation operators. We also illustrate our approach with two successful instantiation of this metamodel:...
The Open Distributed Processing Reference Model (ODP-RM) provides viewpoints and abstract infrastructure guidelines that can be used for a basis for enterprise architecture, especially for an inter-enterprise architecture. The ODP-RM does not prescribe methodology for modeling itself, but provides common vocabulary and focus for description. This paper performs a brief analysis of the ODP-RM (and...
