Assembly Variation Analysis: Liberty's Process Driven Design Tool for Quality

The purpose of this paper is to describe the technical components that support the Assembly Variation Analysis group at the Liberty Development Center of Chrysler Motors. A short chronicle of these elements is presented, as well as a summary of the benefits afforded the user when these tools are properly utilized “up-front” in the advance engineering process.

This is followed by an example of a practical application of these tools to a major assembly process under development at Liberty. An analysis of the simulation results, and a brief outline of future developments is offered.

Also discussed is the development of a graphics program to enhance the simulation software presently used.
