Study on service deployment in C4ISR system integration

Abstract

Service deployment is an important phase of aligning business to IT systems in the Service-oriented Architecture (SOA)-based C4ISR system integration. Current methodologies of service deployment mostly focus on system-level service deployment as well as service composition, while the deployment of enterprise-level services to align business processes to IT systems is ignored. This paper deals with the service deployment for business/IT alignments in the perspective of architecture designing. First, we redefine the service deployment problem in C4ISR system integration, and then propose the process of service deployment based on DoDAF 2.0 to meet the business requirements and goals. Finally, we present a service deployment model based on the Quality of Service (QoS) and use the Immune Genetic Algorithm (IGA) to solve an optimal problem. Through a comprehensive case study, we find that IT systems can align with business by applying our process and model in service deployment.
