Abstract:

Work progressed on two major tasks 1 Modeling for multi-unit systems with units which undergo imperfect repairs before eventual fatal failure and 2 Modeling multivariate life distributions through multivariate conditional hazard rate functions. In the first task, the paper Multivariate imperfect repair, to appear in Operations Research Magazine deals with probabilistic properties four proposed models. In the second task several papers have been written regarding properties of conditional hazard rate functions.
