Other than this, automation and optimization of production engineering was attempted in various fields. Okumoto et al. (2005D) optimized the block allocation on the assembly area using simulated annealing method. Wibisono et al. (2007) optimized block division planning using genetic algorithm and product model. Universal Shipbuilding Corporation (2008) developed a high performance NC Printing Machine, which enables fast printing irrespective of the number of characters and lines to be printed. Information of hull and machinery outfitting can be printed as well as hull structure assembly information, and overall efficiency was substantially enhanced. .
