Zhu, Z. (author), La Rocca, G. (author), Van Tooren, M.J.L. (author)Harness 3D routing in aircraft Electrical Wiring Interconnection System (EWIS) design is very complex because of both the intrinsic complexity of EWIS and the increasing number of design constraints. The complexity hinders the improvement of the design efficiency and makes the design error prone. Considering that many harness components are...conference paper 2015

Zhu, Z. (author), Van Tooren, M.J.L. (author), La Rocca, G. (author)Wire harness design is an increasingly complex task. Knowledge Based Engineering (KBE) and optimization techniques can be used to support designers in handling this complexity. The wire harness design process can be divided in three main parts, namely electrical design, configuration design and geometrical routing. This paper describes the...conference paper 2012
