| 摘 要： | 根据箱梁预制工艺的要求,模具的周转周期T2通常为3～5 d,而文献1]中制梁台座规模优化算法仅适合于模具的周转周期T2=1 d的情况。针对文献1]的局限性,试图通过作图、试算和归纳等一系列工作,找出适用于T2=1,T1]时计算最优制梁台座数和模具数的通用算法,进一步扩大了算法的适用性。同时,结合文献1]的工程实例,利用Matlab语言编程验证了改进算法的可行性。

| Abstract: | According to the requirements of box girder prefabrication process,the turnover cycle of mold is usually 3~5 days,but the optimization algorithm for the scale of girder-fabrication bed in the literature1] is only suitable for those modes with turnover cycle of 1 day.So,contrary to the limitations of the literature1],after a series of work including mapping,calculating,generalizing,this paper proposes universal algorithm for computing the optimal number of the girder-fabrication bed and its mold when the turnover cycle is the any integer at the interval 1 and T1,so as to further expand the applicability of the algorithm.Simultaneously,in combination with those project examples in literature1],the feasibility of this improved algorithm is verified by Matlab programming. |
