An analytical approach to change for the design of reusable real-time software

We present an analytical method for incorporating knowledge about change into the design of reusable real time software components. We apply this method to the construction of algorithmic software solutions that minimize the effect of anticipated changes in the solution. The motivation for our research is based on two premises: software solutions that can easily be adapted to changes in the problem and solution domains are more readily reused; and the reuse of reliable software promotes the construction of high quality software systems and reduces development costs. The paper also briefly overviews our current research goals involving analysis and design methods to enable software engineers to rapidly adapt their real time software solutions to changing application requirements.
