Professor Gyung-Jin Park's research lab specializes in advanced engineering design and optimization, focusing on multidisciplinary design optimization (MDO), robust design, and structural optimization for automotive and mechanical systems. The lab develops innovative methodologies such as MDO based on independent subspaces (MDOIS), meta-model-based crash optimization, and equivalent static load techniques to address complex, non-linear dynamic problems in vehicle safety and vibration control. Emphasis is placed on integrating axiomatic design, design structure matrix (DSM), and viscoelastic material modeling to enhance product performance, reliability, and manufacturability under uncertainty and real-world loading conditions. The lab’s work bridges theoretical optimization frameworks with practical engineering applications in the automotive and mechanical industries.

Robust design has been developed with the expectation that an insensitive design can be obtained. That is, a product designed by robust design should be insensitive to external noises or tolerances. An insensitive design has more probability to obtain a target value, although there are uncertain noises. Theories of robust design have been developed by adopting the theories of other fields. Based on the theories, robust design can be classified into three methods: 1) the Taguchi method, 2) robust
Optimization has been successfully applied to systems with a single discipline. Since many disciplines are involved in a coupled fashion in modern engineering, multidisciplinary design optimization (MDO) technology has been developed. MDO algorithms are designed to solve the coupled aspects generated from the interdisciplinary relationship. In a general MDO algorithm, a large design problem is decomposed into smaller ones which can be easily solved. Although various methods have been proposed fo
As the demands of customers in the modern industry increased, the number of products, and the variety of components has increased. These issues have led to difficulties in product development and production. Modularization of products has advantages such as cost reduction, product development time reduction, and production time reduction. Modular design of products has been studied in the design activities of the modern industry. In this study, a modular design method is proposed to design a mod
The vehicle performances for the side impact test and the roof crush test are dependent on the side structure design of a vehicle. Crash optimization can be employed to enhance the performances. A meta-model-based structural optimization technique is generally utilized in the optimization process since the technique is simple to use. However, the meta-model-based optimization is not suitable for problems with many design variables such as topology and topometry optimizations. A crash optimizatio
