Abstract  A parallel system is the most fundamental redundant system because multiple identical units are working concurrently to perform successfully an objective work. As one extended system, we define newly a parallel system with x (0 < x < ∞) units, and obtain its reliability measures such as MTTF, median and failure rate. In particular, we have an interesting result that the failure rate moves strangely to decrease initially, and after that, to increase strictly for a given x (0 < x < 1). Furthermore, we apply this definition to seriesparallel and parallelseries systems, and derive similar interesting results. It would be newly adapted to move uncertain and complex systems as information and technologies have rapidly developed.
