REQUIREMENTS COUPLING TO REDUCE THE IMPACT OF REQUIREMENTS CHANGES ON THE DEVELOPMENT SOFTWARE-INTENSIVE SYSTEMS R.Subhashni Research Scholar, Research & Development Centre, Bharathiar University, Coimbatore, India subha_shnir@yahoo.co.in Dr. R. Latha Professor & Head, Department of Computer Science and Applications, St. Peter’s Institute of Higher Education and Research, Chennai, India ABSTRACT In recent years, complex software program-intensive systems have resulted from the combination of various unbiased systems, thus leading to a new sophistication of systems known as systems of system (SoS). Software model-based development, software version- based development assurance and the integration of static and dynamic best assurance activities are getting increasingly more relevant within the development of software-intensive systems. Thus, we always concentrate more on experimental learning viewed at examining the secure regarding improvements on quality and cost effective in software development. Reducing the impact of requirements changes on the development software intensive systems helps to provide the smart product by improving the Quality of Service (QoS) with reduction in the cost also. This paper provides the concept of semantic coupling genetic optimization system that can be applicable for software intensive system to improve the QoS during the software International Journal of Pure and Applied Mathematics Volume 119 No. 12 2018, 16155-16168 ISSN: 1314-3395 (on-line version) url: http://www.ijpam.eu Special Issue ijpam.eu 16155
