    Abstract

    The proposed availability demonstration test (ADT) is an extension of the work of Usher and Taylor [Usher, J. S. and Taylor, G. D., “Availability Demonstration Testing,” Qual. Reliab. Eng. Int., Vol. 22, No. 4, 2006, pp. 473–472] and provides reduced testing time. The ratio of the cumulative repair times and the cumulative failure times are then compared to an upper and lower limit. Values of the ratio above the upper limit signal a reject decision. Values below a lower limit signal an accept decision. Values in between the limits signal a repeat of the test. The advantages of the proposed test are discussed over the test plan given by Usher and Taylor. This method should be of great value to consumers and producers who want to ensure that bad systems are rejected and good systems are accepted based on system availability.
