“…However, a recent study on door assemblies shows that good assemblies, i.e. assemblies with high Cpk values, do not necessarily result in high customer satisfaction [14]. Conversely, assemblies with poor Cpk values do not always result in low customer satisfaction.…”

This paper introduces three auto body build concepts: net build (NB), functional build (FB) and integrated build (IB). Most manufacturers design and validate their vehicle launches using the NB concept. This concept is shown to be expensive, time consuming and not effective value added. Functional build has found growing acceptance as being preferable over NB. Functional build has tended to find the greatest acceptance as a die buyoff procedure for individual parts based on subassembly quality. Aspects of FB are shown in a case study where the manufacturer claimed to use FB for die development, but critical elements were omitted and opportunities lost. The integrated build (IB) process is an extension of the FB approach. It is a more inclusive process that considers the entire vehicle and requires closer coordination with product design. Aspects of IB are also shown in two case studies. In the first, IB concepts were included in the design process, which enabled the company to implement an effective material introduction strategy. The second is a comparison of the product development timelines of two companies and shows how IB concepts can shorten lead and production ramp time.

The Digital Body Development System (DBDS) is 4 year project to shorten the time to launch vehicles by improving the launch problem solving process. The project is based on two concepts: virtual functional build and an intelligent agent based decision support system. This paper presents a novel architecture for the decision support system that streamlines the launch process through the integration of a virtual assembly simulation, problem identification, and solution generation and evaluation. Following the virtual functional build process, the architecture deploys a number of multi-agent systems to provide system functionality, such as problem knowledge retrieval, solution generation, modification, and evaluation. The architecture has been implemented and will be explained on a simple 2-D door model and a casebase of 100 cases. Results show that the DBDS can find the correct solution much faster than a random search and can automatically implement and evaluate the solution.
