Abstract System administrator deals with many problems, as computing environment becomes increasingly complex.

Systems with an ability to recognize system states and adapt to resolve these problems oﬀer a solution. Much experience

and knowledge are required to build a self-adaptive system. Self-adaptive systems have inherent diﬃculties. This paper

proposes a technique that automatically generates the code for the self-adaptive system. Thus the system is easier to build.

Self-adaptive systems of previous research required high system resource usage. Incorrect operation could be invoked by

external factors such as viruses. We propose an improved self-adaptive system approach and apply it to video conference

system and robot system. We compared the lines of code, the number of classes created by the developers. We have

conﬁrmed this enhanced approach to be eﬀective in reducing these development metrics.
