【Abstract】 In present paper, we study the well posed problem of a system which is the standby, repairable, human and machine with two identical units, we prove by the semigroup theory that there exists unique a nonnegative solution of the system. Further, we show that 0 is an eigenvalue of the system and the corresponding eigenvector is nonnegative. Therefore the stead state of the system follows.更多还原
