This paper describes the development of a robust and efficient system for optimization of structural design of artifacts on the Grid, considering the following requirements: (1) Computation subtasks with less dependency are processed asynchronously, and (2) An optimal solution with specified accuracy is obtained in a robust and prompt manner. To satisfy Req. (1), evaluation calculations such as finite element (FE) structural analyses are asynchronously performed on the Grid. Each FE analysis is performed using an open source parallel FE system named ADVENTURE. To satisfy Req. (2), a robust and efficient optimization algorithm based on real-coded genetic algorithms is developed. In addition, robust processing mechanisms are implemented to perform a whole of computation on the Grid without interruption. In this study, we test the following two kinds of Grid environments: a group of PC clusters distributed in remote sites and one of Japanese national Grid projects named ITBL (IT-based Laboratory). Practical performances of the developed system are demonstrated through some examples.
