Research on the Arranging and Patchwork Design for Storage Tank Bottom Based on Sinovation

In the paper, to solve the patchwork problem of large chemical storage tank bottom, theoretical researches on arranging special-shaped parts are carried out. The heuristic layout algorithm with dynamic decision layout order and based on graphics position strategy is proposed. According to the algorithm, basing on Sinovation platform, using the object- oriented programming language C++ and Visual Studio tools, the arranging and patchwork system is designed and developed. And the application researches are performed with the system. The results show that, comparing with the rectangular envelopment algorithm, the plate utilization ratio is increased with the patchwork algorithm as proposed in the paper.
