    This paper discusses the use of computers in calculating the unserviceable probability of a class of telecommunication networks. The unserviceable probability for a pair of terminals in the network is derived and is so complicated that it is not feasible to calculate without the use of a computer. Under the condition that every junctor in the network has a small ratio of mean service time to mean ... View full abstract»

    By using data on the failure rates of electronic components collected by a European Bank, we try to form an idea on the validity of the various models (Bazovsky model, MIL HDBK-217A standard model, exponential model, RADC TR-67 models) that represent the variations of the failure rate with respect to the thermal and electrical stresses. Two different approaches have been programmed on a computer: ... View full abstract»

    The error analysis problem is the resolving of a limited set of measurements in terms of a large set of possible but improbable physical errors. The relation between the measurements and the errors is modeled in part as a set of linear undetermined equations ¿v = A¿r, where ¿v is a vector of the measurements and ¿r is a vector of error parameters, and in part by specification of the relations ...

    This paper develops a cost-based procedure for allocating the availability parameters (repair times and failure rates) to the various components that make up a system. The allocation is handled as a cost minimization problem, subject to the constraint of meeting a system availability requirement.
