基于隐枚举的重载运输下桥梁结构加固方案优选

Optimization of Bridge Structure Reinforcement Methods Under Heavy Traffic Transport

为解决重载运输中的桥梁加固/重建方案选择困难问题,提出了采用线性规划中的0-1优化模型来选择最优的桥梁处理方案的方法,并在文中对该问题的变量、约束进行了详细的讨论。最后将该模型应用于一个重载物件在运输中遇到的加固方案选择中,利用lingo语言,采用隐枚举方法进行求解,得出了5座桥的最优处理方案。

In order to determine the difficulty in selecting the bridge reinforcement/reconstruction methods in heavy-haul transportation,the 0-1 optimization model in linear programming was proposed.This paper offered a scheme which conclude modeling method and solve method.The variables and constraints of the problem were detailly discussed.Finally,the model was applied to the selection of reinforcement schemes encountered in the transportation of a heavy-duty object.We use the Lingo language and the implicit enumeration method to solve the problem,and the optimal treatment scheme of the five bridges was obtained.
