【Abstract】 Tabu Search (TS) method is used for the optimization of cylindrical latticed doublelayer shell. Grid size, vault thickness and risetospan ratio of the shell are optimized under the condition of the minimized cost of the shell based on binary system or on decimal system. Simulation results show that the shell cost optimized with the TS method is cheaper than the one with the Genetic Algorithm (GA) method, and TS method will be a good candidate for the shell optimization in the future.更多还原
