【摘要】：摘要：铁路燃油供应在铁路运输中起到重要的作用,高效、经济地组织铁路燃油供应,做好内燃机车燃油供应管理工作,对保证铁路运输安全正点、优质服务、降低运输生产成本、提高经济效益具有重要意义。本研究从我国铁路燃油供应实际出发,在对铁路燃油供应业务的运作流程和业务模式的研究基础上,结合对供应体系中库存及运输这两大成本的分析,采用库存-运输联合优化的方式来进行系统优化,优化目标为总成本最小化。首先,论文结合铁路燃油供应系统的现状分析,建立了基于VMI的铁路燃油库存-运输联合优化模型,利用该模型能够实现求解需求确定的库存和运输联合优化的问题。其次,论文采用了迭代遗传算法对模型进行求解,利用EOQ方法求解初始最优订货量,再将此订货量带入到运输成本部分应用遗传算法求解运输成本,之后代回优化模型中求得最优订货量。本文采用迭代算法和平均迭代算法,对最优订货量进行双重保障,以求得最终的最优订货量和总成本,以及运输路径。最后,本文针对模型开发了一个运算程序,结合具体的算例数据对模型的正确性和可行性进行验证,通过计算达到了对铁路燃油系统库存-运输联合优化的目的,求出了系统的最小成本,订货量,订货次数和运输路线。
[Abstract]:Abstract: railway fuel supply plays an important role in railway transportation. It is efficient and economical to organize railway fuel supply, to do well in diesel locomotive fuel supply management, to ensure the safety of railway transportation and to provide high quality service. It is of great significance to reduce the cost of transportation production and improve economic benefits. Based on the research of the operation process and business model of railway fuel supply business, this study combines the analysis of inventory and transportation costs in the supply system, which is based on the actual situation of railway fuel supply in China, and on the basis of the research on the operation process and business model of the railway fuel supply business. Inventory-transportation optimization is used to optimize the system. The optimization goal is to minimize the total cost. Firstly, based on the analysis of the current situation of railway fuel supply system, a railway fuel stock-transportation joint optimization model based on VMI is established, which can be used to solve the problem of joint optimization of inventory and transportation. Secondly, the iterative genetic algorithm is used to solve the model, the EOQ method is used to solve the initial optimal order quantity, and then the order quantity is brought into the transportation cost part. The genetic algorithm is used to solve the transportation cost. The optimal order quantity is obtained from the optimization model. In this paper, the iterative algorithm and the average iterative algorithm are used to guarantee the optimal order quantity, so as to obtain the final optimal order quantity and total cost, as well as the transportation path. Finally, this paper develops an operation program for the model, and verifies the correctness and feasibility of the model by combining the concrete example data. The purpose of the joint optimization of inventory and transportation in the railway fuel system is achieved by calculation. The minimum cost, order quantity, order number and transportation route of the system are calculated.
