摘要
多式联运作为广泛采用的快捷运输组织形式,其路径优化不仅要考虑总成本最小化问题,整个运输过程的时效性也至关重要。以用户规定的时间限制作为重要约束,建立了以运输总成本最小为目标的多式联运路径优化模型,并设计交叉熵算法(CE)对模型进行求解,最后通过算例分析,验证了模型的合理性和有效性。
Inter-modal transportation is a widely used form of shortcut organization. Time limit of Inter-modal transportation is crucial for path optimization, in addition to considering the total cost minimization problem, also need to consider the time requirements of the entire transportation process. This paper has established the minimum Inter-modal transportation cost as the total target of route optimization model, and has solved it with cross-entropy method （CE）, finally, and verified the validity and rationality of the model through the case analysis.
