Engineering Support Systems for Industrial Machines and Plants

In the business of industrial machines and plants, rapid and detailed estimates for planning installation, replacement of equipment, or maintenance work are key requirements for meeting the demands for greater reliability, lower costs and for maintaining safe and secure operation. These demands have been addressed by developing technology driven by IT. When replacing equipment at complex building or plants with high equipment density, the existing state of the installation locations and transportation routes for old and new equipment need to be properly measured. We have met this need by developing parts recognition technology based on 3D measurement, and by developing high-speed calculation technology of optimal routes for installation parts. This chapter provides an overview of these development projects with some real business application results.

Near optimal assembly sequence generation

Novel near optimal algorithm is proposed in order to compute assembly sequence with practical computation time. The proposed algorithm guarantees linear increase of computation time with regard to number of candidate assembly processes. Computation time and objective function values with respect to search space size are examined with a practical assembly product.
