Abstract(in English) The authors have been insisted on the importance of reliability management for IP networks constructed of commercial equipments, and studied the management technique using the actual failure data. Failure rate, unavailability, and maintainability are the typical measures for the reliability management of telecommunication networks. These reliability measures could not be exactly estimated using the previous reliability methods because the number of equipments and users change in communication networks. We have clarified that the service outage times have the mixed log-normal distribution and that the actions for repairs is related to the number of mixtures. However, the computation of maintainability is not established. In this paper, we study on the computation of maintainability with R: a freely available language and environment for statistical computing and graphics. The actual analysis is executed with concise R scripts.
