中文摘要: 服务网络设计是运输物流的核心问题,比车辆路径VRP模型更适合建模货物运输的中转、充实等增效策略,因此更适用于解决大规模运输网络优化问题。随着用户对服务质量和可靠性要求的不断提高,随机服务网络设计近年来成为一个研究热点,但国际上目前对于该问题的求解算法还远远达不到实际应用要求。为此,本项目创新性的从随机服务网络设计的场景树(Scenario Tree)入手,研究场景树在服务网络设计应用中的压缩方法,以减少随机规划两个阶段之间的迭代次数来达到提高算法效率的目的。项目拟分别研究动态场景聚类法和演化计算场景分类法,结合以场景类为基础的分割法、整数规划和最新的启发式领域搜索算法,从根本上提高随机网络优化算法性能,并采用国际标准问题集和宁波港内陆集卡运输真实数据加以测试验证。研究将大大提高现有随机服务网络设计算法效率,对国内外相关运输网络问题具有巨大经济价值和环境效益。

英文摘要: .Service network design is one of the core problems in freight logistics. Compared to vehicle routing problem, service network design can readily model freight transfers and consolidation and, therefore, is more suitable for large transportation network optimization. Due to an uncertain environment in which freight transportation operates and reliability requirements from users, stochastic service network design is becoming a focused research area recently. In contrast to the other relevant research which concentrates on optimization algorithms, this project mainly focuses on the scenario tree compression in the context of service network design. In this way, we can reduce the number of iterations between the two stages of stochastic programming. To achieve this, we will investigate both the dynamic scenario clustering methods and evolutionary based scenario classification approaches. These will be combined with decomposition based methods, integer programming approaches and latest meta-heuristics to improve the performance of algorithms for the stochastic service network design. These algorithms will be tested on the well-known international benchmark instances as well as the real world container transportation problem at Ningbo Port. The project will advance the state-of-the-art algorithms for stochastic service network design significantly. It will also significantly benefit relevant practical transportation network design applications both economically and environmentally.
