Leverage the Power of Field Data

Liebherr-Aerospace repairs more than 40,000 pieces of equipment each year. Repair data contains a huge amount of information. High-value information is only available using smart tools, rigorous processes and advanced statistical methods. This presentation gives an overview of the data collection processes and tools. The main focus lies on statistical methods used to get relevant data. The performance and interest of the Weibull model, Monte-Carlo simulation and multivariate analysis is then shown in several case studies: failure prediction for production forecast, overhaul benefits and tailored maintenance cost. The presentation ends with next steps to increase the impact of field reliability to the company.

Key Words: Data Management, Life Data Analysis, Stress–Strength Analysis, Reliability Value
