摘要
运用传统方法进行工期-费用优化可以得到最优解,但工期与费用同时进行优化,其计算量很大,而启发式算法及各类智能算法能减小计算量,但不能保证是最优解。依据所分析的结合循环法与动态规划法的工期-费用优化原理,以青弋江特大四线客运专线桥1号块为研究对象,将工期与费用分别进行优化。
Duration and cost optimization for construction can get the optimal solution by using traditional methods, but need duration and cost optimization at the same time, a lot of calculation. Heuristic algorithm and various intelligent algorithms can reduce the amount of calculation, but can't guarantee to be the optimal solution. The principle of duration and cost optimization was analyzed from the cycle method and dynamic programming method. Based on the principle, duration and cost was optimized separately with the 1st block of Qingyi river bridge of large four-wire passenger as research object.
