Flexible manufacturing is a multi-faceted term that has been used in the automotive industry to imply a multitude of manufacturing criteria. A prominent area of application for such criteria in the automotive industry is the body assembly process. The assembly process is, in turn, divided into a number of sub-processes which include fitting car doors to body openings. As these operations take place before the painting of the car body, they are commonly known as Body in White processes. The door fitting problem is ranked within the top issues of car-quality, since an inadequate door fit causes water leakage, wind noise, difficulties in closing and adversely affects the aesthetic value of the car. This thesis presents a novel computer aided method for fitting manufactured car doors to manufactured car body openings using measured points, by laser sensors, on the door and opening peripheries. The fitting process is modeled as an optimization problem where the door location and orientation parameters are the independent variables and the deviation from the nominal gap is the objective function to be minimized.
