Using modal decomposition method for solving vehicle-bridge coupling equation to analyze the dynamic response of the simply-supported beam bridge to different vehicle load and speed.The half car model was used as vehicle,and Euler-Bernoulli beam was used as the simply-supported beam bridge.Using the ANSYS software,the simply-supported beam bridge span deflection curve was obtained.The results show that vehicle load increase made the bridge span deflection increase;the beam’s span deflections were 0.028 m and 0.049 m respectively in the standard vehicle load and 100% vehicle overload.As the vehicle speed increased,the simply-supported beam bridge span deflection reached at its peak value at the vehicle speed of 60 km/h and vehicle-bridge resonance was resulted in.

An optimal distribution center location can not only improve the efficiency of the logistic system,but also reduce the cost of logistics system as well.In the current society,time has become a new resource of competitive advantage,so taking into account the time constraints on the distribution center location model is undoubtedly a breakthrough.A model of the logistics distribution center location is proposed.In the new model it is necessary to know the upper limit of the number of the required distribution center,thus the relaxation of the conditions to be determined in the previous model is achieved.Finally 0-1 programming cutting plane method,which is the optimization methods,is used for model solution.At last the results indicate that the model is reliable,and the methods reduce the computational complexity of the algorithm.
优化配送中心选址不仅可以提高物流系统的效率,还可以降低物流系统的成本。在当今社会,时间已经成为一种新的竞争优势资源,因此考虑到时间约束的配送中心选址模式无疑是一种突破。提出了物流配送中心选址模型。在新模型中,需要知道所需配送中心数量的上限,从而实现了对之前模型中需要确定的条件的放宽。最后采用最优化方法0-1规划切割平面法求解模型。结果表明,该模型是可靠的,并且该方法降低了算法的计算量。
