halfbeak: Unscheduled maintenance actions for the U.S.S. Halfbeak

In Auburngrads/SMRD: Statistical Methods For Reliability Data

Description

Ascher and Feingold (1984) present a dataset containing unscheduled maintenance actions for the U.S.S. Halfbeak number 4 main propulsion diesel engine over 25,518 operating hours. For each observation, an event was recorded as either start (denotes the start of the observational period), end (denotes the end of the observational period), or report (denoting that an unscheduled maintenance action was reported). The data were analyzed to determine if the system was deteriorating (unscheduled maintenance actions were being reported more frequently as the system ages)

Format

A data.frame with 73 rows and 3 variables:

[, 1]	unit	Unit designator code	Categoric
[, 2]	hours	Accumulated time at event	Numeric
[, 3]	event	Event observed at hours (Start/Report/End)	Categoric
