Influences of code cloning in software maintenance cost

Major portion of software cost will be occupied by software maintenance in a software project life cycle cost. Customer will be thinking that accommodating changes to the software even after product delivery is easy, but it enormously affects the maintenance cost. Unless we compare particular software with similar or different versions, we will not know that it has more copied fragments in it. But maintenance plays big role in improving software quality. Code clones or copied fragments make it difficult to modify the software. Different approaches proposed to overcome this problem. In this paper we present an analysis of a cost model which considers various parameters.
