The digital engineering is considered as a powerful technology for improving the competitive power of product. Especially optimal design is important technology in it. The product which has competitive power usually has a core technology in the design and manufacturing fields. The spot weld technology, positions and number of spot weld on white-body, indicates the technological level of automotive company. The technology is typical core technology. In this paper, Authors propose a meta-heuristic method, integer optimization method on discrete type, by using hybrid meta-heuristics for aiding engineering field. The proposed method is applied to some benchmark functions to check the performance, and is confirmed that it improves amount of computational cost and convergence of the optimal solution. Furthermore, Authors deal with the optimization of spot weld positions by the proposed method for aiding the core technology of the vehicle design. The effectiveness of the proposed method is discussed through the optimization of benchmark functions and spot weld positions.
