Optimised Multi-Stage Sampling Procedures (OMSP): Approaches for Reliability Analysis within Field Observation

This presentation shows "Optimised Multi-Stage Sampling Procedures" (OMSP) – and approaches of current research work. Integrating the new "Field Damage Analysis" (FDA) process that was developed by the Cologne University of Applied Sciences in cooperation with leading automotive companies and suppliers, the OMSP supports optimised sampling sizes and drawing-intervals within product field observation with the goal of: 1) detecting the major causes of damage through the technical analysis of the field damage components and 2) reducing costs of the reliability analysis

Besides the OMSP approach, the FDA process includes additional statistical methods, such as the "Differentiation of Complex Damage Causes" (DCD) algorithm and "Weighted Combined Function" (WCF) approaches, to identify potential damage causes before the technical analysis and thereby supporting the OMSP approach to select useful damaged field components.

Key Words: Reliability Analysis, Field Observation, Detecting Damage Causes
