Research On The Aapplication Of System Of Systems (SoS) In Software Engineering

The two concepts of SoS and emergent behaviors and their theory and applications for large-scale promote the developments of software systems and Internet application development, so in the field of computer software internationally widespread attention. With advances in technology and system requirements in various areas of the continuous development of applications in many areas difficult to support a single system, often in different stages of formation, using different techniques for different owners,different functional independence system,associated by some means of coordination,complex business to provide automated,end to end support. At present,the domestic software sector research in this area is still less.This research project is mainly for the large-scale software-intensive systems.According to the characteristics of these systems,the SoS and emergent methods are applied to their life cycle and engineering process.The research work is based on the track to the main research directions and applications of the current international SoS and emergent behaviors and the past research and application of framework methods,and illustrates the importance of framework,gives the abstract representation of SoS architecture,and the two direction of life-cycle in the development of SoS.This paper also proposes functionality architecture and map it to NGOSS.The functional analysis of CRM explores the application of SoS in software engineering,and proves the SoS can achive its expected results.The innovation of this paper is the integration of SoS and framework methods to explore the development direction of the life cycle of SoS,and provides the additional methods for the complex systems of software engineering.Taking these studies,this paper applies the SoS approach——framework approach,Petri net method,reachability graph method to analysis and evaluate the feature realization of―customer acceptance‖in Fujian Fujistu CRM system.
