1. 环境友好型商业物流系统模式的推荐我们调查了目前日本几家物流公司的环境友好型商业物流系统模式的行动，并推荐了环境友好型商业物流系统模式2。具有电弧容量约束的供应链网络设计问题的近似求解方法研究了具有电弧容量约束的供应链网络设计问题的最快近似求解方法。该方法采用强分解强迫约束，并结合柱生成法和容量标度法。结果表明，本文提出的近似解法是现有近似解法中最好的一种。考虑实际运输成本的供应链网络设计问题的近似求解方法研究了具有分段线性函数的实际运输成本的供应链网络设计问题的快速近似求解方法。这些分段线性函数对应于门到门包裹、低于卡车装载和卡车装载服务的成本函数。我们证明了我们的近似解法比其他近似解法要好。车辆路线/设施供应链网络设计模型综合地理信息系统的开发采用退火法和双上升法开发了车辆路线/设施网络设计模型的分析系统。通过将该分析系统与地理信息系统相结合，开发了用于车辆路线/设施网络设计模型的综合地理信息系统。针对日本某企业的企业重组问题，建立了以降低运输成本为目标的大规模产品到工厂分配/再分配模型，并采用禁忌搜索方法求解该模型的近似解。少

1. The recommendation of environmentally-friendly business logistics system modelsWe surveyed current actions of environmentally-friendly business logistics system models in several Japanese logistics companies, and recommend environmentally-friendly business logistics system models2. The development of approximate solution methods for the supply chain network design problem with arc capacity constraintsWe developed the fastest approximate solution method for the network design problem with arc capacity constraints. The strong disaggregated forcing constraints are used for our formulation and the column generation method and the capacity scaling method are combined for our method. We show that our approximate solution method is the best method among other developed approximate methods.3. The development of an approximate solution method for the supply chain network design problem with real transportation costsWe developed a fast approximate solution method for the network design proble … More m with real transportation costs, which have piecewise linear functions. These piecewise linear functions correspond to the cost functions of door-to-door parcel, Less-than-Truck-Load and Truck-Load services. We show that our approximate solution method is better than other approximate methods.4. The development of integrated geographical information systems for the vehicle routing / facility supply chain network design modelsWe developed the analyzing systems for the vehicle routing / facility network design models using annealing or dual ascent methods. By linking this analyzing system and geographical information systems, we developed the integrated geographical information systems for the vehicle routing / facility network design models.5. The development of a product-to-plant allocation/reallocation model and its approximate solution methodFor a corporate realignment of a Japanese company, we developed a large scale product-to-plant allocation/reallocation model to reduce transportation costs, and its approximate solution method by a tabu search method.
