Criticality analysis from maintainability point of view

Maintainability performance of a system depends on component's performance. Some components have more influence on the system maintainability, which can identify by use of importance measures. The aim of this paper is to develop the concept of maintainability importance measure, which is useful for maintainability improvement. Therefore, this paper will present the concept of maintainability importance measures for the criticality analysis of each component. The result of analysis will be useful for allocation of resources in order to improve maintainability of the system.
