摘要:

运输成本占物流成本的三分之一,因此运输系统对物流系统的性能有很大的影响。本文提出了一种自适应数据驱动的创新模块化方法,用于解决物流领域的车辆路径问题(VRP)。该工作包括两个基本单元:(i)一个创新的多步算法,成功和完全可行的解决物流中的VRP问题,(ii)一个自适应的方法来调整和设置所提出的算法的参数和常数。该算法结合了几种数据转换方法,算法和禁忌搜索。此外,由于算法的性能取决于控制参数和常数的设置,提出了一种预测模型,根据历史数据自适应地调整这些参数和常数。所获得的结果进行了比较,使用决策支持系统与预测模型:广义线性模型(GLM)和支持向量机(SVM)。该算法,随着控制参数,其中使用的预测方法获得,被纳入一个基于Web的企业系统,这是在波斯尼亚和黑塞哥维那的几个大的分销公司使用。将该算法的结果与一组基准实例进行了比较,并在真实基准实例上进行了验证。给出了在实际环境中的成功的可行性。

英文摘要:

Transportation occupies one-third of the amount in the logistics costs, and accordingly transportation systems largely influence the performance of the logistics system. This work presents an adaptive data-driven innovative modular approach for solving the real-world Vehicle Routing Problems (VRP) in the field of logistics. The work consists of two basic units: (i) an innovative multi-step algorithm for successful and entirely feasible solving of the VRP problems in logistics, (ii) an adaptive approach for adjusting and setting up parameters and constants of the proposed algorithm. The proposed algorithm combines several data transformation approaches, heuristics and Tabu search. Moreover, as the performance of the algorithm depends on the set of control parameters and constants, a predictive model that adaptively adjusts these parameters and constants according to historical data is proposed. A comparison of the acquired results has been made using the Decision Support System with predictive models: Generalized Linear Models (GLM) and Support Vector Machine (SVM). The algorithm, along with the control parameters, which using the prediction method were acquired, was incorporated into a web-based enterprise system, which is in use in several big distribution companies in Bosnia and Herzegovina. The results of the proposed algorithm were compared with a set of benchmark instances and validated over real benchmark instances as well. The successful feasibility of the given routes, in a real environment, is also presented.
