为解决铁路行包配送点的选址问题,在回顾总结物流节点选址问题的动态模型和概率模型的基础上,结合铁路行包运输实际,在一定的前提及假设条件下,建立不确定需求的铁路行包配送点选址问题的数学模型.针对模型求解需要输入的数据量较大、对数据的调整非常灵敏等增加求解困难程度的情况,通过求客户需求的分布函数,进行曲线拟合,对客户需求分布函数积分得出客户需求量,将不确定需求的选址问题转化为确定性选址问题.该方法使求解得到简化、切合实际.
In order to solve the problem of locating distribution points of railway parcels, on the basis of reviewing the dynamic model and probabilistic model of the logistics node location problems, combining with the actuality of railway parcel transportation, under certain conditions and assumptions, we establish the uncertain demand The mathematical model of the problem of locating distribution points of railway parcels is proposed.Aiming at the problem that the model needs to input a large amount of data and the data adjustment is very sensitive to increase the degree of difficulty of solving the problem, curve fitting is performed by finding the distribution function of customer demand , The customer demand distribution function is obtained by integrating the customer demand distribution function, and the problem of location with uncertain demand is transformed into the problem of deterministic location.This method makes the solution simple and practical.
