The automotive industry is engaging in a global production strategy for simultaneous achievement of QCD (quality, cost and delivery) in an effort to prevail and survive in the worldwide quality competition. In an effort to realize this, the authors have proposed the high quality assurance system for simultaneous achievement of QCD by a change to super short period development designing, the Highly Reliable CAE (Computer-Aided Engineering) Model and demonstrated its effectiveness. To realize this, the rational integration of overall optimality and partial optimality needs to be achieved through the process of problem theory algorithm modeling calculator as a technical requirement to be included in Bolt Tightening Simulation System.

In this paper, the authors propose a model for a highly precise CAE analysis approach, which is intended to contribute to the regeneration of development and design. This model has been applied with significant results in making proposals for bolt tightening behavior analysis, which continues to be an area of concern.
