Model generation device for life prediction, model generation method for life prediction, and model generation program for life prediction

摘要

The model generator 30 includesBased on the fault history information 301 of the subject to predict the life spanThe order statistic calculation method 310 is used.A result information generator 31 for generating the result information 311 representing the relationship between the use time and the reliability of the object andAfter setting the number of divisions to divide the usage time into one or more periodsFor each period that is divided into the number of partitions setThe probability distribution model generator 32 generates a probability distribution model 321 approximatingFor each divisionThe probability distribution model 321 of the probability distribution model 321 forA calculation part 33 to be calculated using the information quantity reference 330 andA decision unit 34 for determining the probability distribution model 321 at the number of divisions in which the degree of suitability is the highest isBy providingUsing probability distribution models for reliabilityTo predict the life expectancy of the objectImprove its prediction accuracy.
