The recent real time systems have the needs of system expandability with heterogeneous functions and operations. High assurance system is very important for such systems. In order to realize the high assurance system, we research the autonomous step-by-step construction technique based on assurance evaluation. In this paper we propose the average functional reliability as the best index to indicate the assurance performance for system construction. We also propose the autonomous step-by-step construction technique to decide the construction sequence to maximize the assurance performance.
