摘    要:Ⅰ.Intreduction It is Well known that series system is one of the most essential and important medels in reliability theory and application.A series system of twe units operates if and only if both units operate.However,in practice,unit 1 upon failure may shut off unit 2 but not vice versa.For example,failure of the power supply may shut down an electronic device but not vice versa.Barlow and Hudes first discussed the asymptotic measures of such a system performance.Next Khalil reviewed the results on availability of series systems with various shut-off rules,introduced combination concepts of shut-off rules,and extended the results
