White Paper - Modeling and Optimizing Wire Harness Costs for Variation Complexity
An automotive wire harness rarely has just a single part number that can be ordered and installed in a vehicle. Typically, there are many different versions of the same harness based on the orderable content in the vehicle. These versions (often called harness levels) will have unique part numbers. The quantity of these levels and their content is what is typically called complexity and it has a significant impact on the cost of the harness.
Quantifying these costs is often very difficult especially with manual methods of deriving and costing the complexity solution. Therefore, traditionally, harness costing has focused on the piece cost of each harness level. When these complexity related costs are considered it is typically with overly simplified cost modeling techniques.
This paper will focus on the quantification of these complexity related costs so that they can be modeled allowing automated algorithms to optimize for these costs. A number of real world examples will be provided as well. Since no two businesses are alike, it is the aim of this paper to provide the foundational knowledge and methodology so the reader can assess their own business to model how variation complexity costs affect their business.
