Title: Within 100 characters Automating Weibull analysis of field vehicle claims under various trouble-free conditions using JMP Abstract: Within 500 characters Weibull analysis technique is used as a method to analyze the reliability of a vehicle. Weibull analysis requires time data. Basically, the time information included in claim data is the date of sale / repair date / mileage at the time of repair, so Weibull analysis is generally performed using date data with a start and end point. However, when Weibull analysis based on mileage is necessary for purposes such as the driving characteristics of the vehicle model, warranty, and whether development goals are achieved, the mileage of a trouble-free vehicle must be estimated through various assumptions. In this process, in order to understand the Weibull analysis results according to the trouble-free calculation method, JMP's Life distribution function / function to save the analysis results as a script / Weibull analysis according to various trouble-free mileage calculation methods set using JSL An automated technique was used to quickly compare results. Through this, it was confirmed that there was a significant difference in the Weibull analysis results based on date and mileage, and it was possible to select a Weibull shape parameter with a high probability using engineering knowledge under various conditions. It can be seen that not only Weibull analysis but also various preprocessing conditions to increase the accuracy of analysis can be performed using the highly flexible functions of JMP.
