摘要：In this paper, we study the
reliability and availability characteristics of a repairable system consisting
of two subsystems A and B in series. Subsystem A consists of two units A1 and A2 operating in active parallel while subsystem B is a single
unit. Failure and repair times are assumed exponential. The explicit
expressions of reliability and availability characteristics like mean time to
system failure (MTSF), system availability, busy period and profit function are
derived using Kolmogorov forward equations method. Various cases are analyzed
graphically to investigate the impacts of system parameters on MTSF, availability, busy
period and profit function.
