Vendors of computer aided design (CAD) technology and tools have embraced the concept of Product Lifecycle Management (PLM), and now offer suites of software that cover most aspects of the design, build, use and maintenance of products. The Boeing 787 Dreamliner™ program is an example of PLM implementation on a very large scale. Human modeling technology is an important component of the PLM tools, and has been integrated into the 787 design process. In order to complete this integration, much work was done on identifying the key users and design processes that were most impacted by the use of human modeling. This paper will describe how processes and standards for human modeling were developed and applied throughout the 787 program.

The purpose of this paper is to provide a general process for human model analysis in the digital mock-up environment. It is also intended to provide some basic guidelines for the use and application of human models. This document is intended for anyone who will be performing human model analyses. It is assumed that the person performing the analysis has at least a minimal level of training in the use of the software involved. Note that this document is limited to anthropometric and ergonomic modeling.

Validation of a new reaching algorithm for the Boeing developed CATIA Human Model was conducted prior to production release of the software. The validation covered both normal and maximum reach capabilities. Human subject and computer generated reach data were compared. For normal reaching, both the subjects and human models reached to the targets that were within reach, but the final body positions were not the same. For the maximum reach validation, problems with both the software and the data collection technique were discovered. Despite the discrepancies and problems found, the CATIA human model was found suitable for its intended use.
