【摘要】：近年来,水泥企业集团化以及国家鼓励散装水泥的使用,使得散装水泥运输需求不断增长。然而,散装水泥运输业务固定资产投入大,运输需求具有季节波动性,导致水泥企业面临着散装水泥运输成本过高、服务水平较低等问题。基于这一背景,本文站在水泥企业的角度,以降低运输成本、合理利用外协车辆资源和保证服务水平为目标,围绕水泥企业的散装水泥车辆优化配置问题做了相关研究：首先,从散装水泥物流发展的政策环境、配送车辆的特点和常见的车辆配置方式3个方面对散装水泥车辆配置现状进行分析,在此基础上运用“自制／外购”决策分析矩阵,分析水泥企业采用“自有车辆+外协车辆”混合的车辆配置方式的形成和优势。其次,结合散装水泥运输的特点和车辆优化配置的实际情况,分析散装水泥车辆优化配置的3个主要影响因素,包括散装水泥运输需求量、外协车辆市场情况及自有车辆和外协车辆的运营成本等,这些因素共同影响着散装水泥车辆的优化配置。最后,根据散装水泥车辆优化配置的影响因素分析分别建立了无合同约束下和战略合作协议下总运输成本最小的散装水泥车辆优化配置模型。最后使用实际案例“JD水泥的散装水泥车辆优化配置”进行了模型的验证和分析,为水泥企业的散装水泥车辆优化配置提供指导。
[Abstract]:In recent years, the group of cement enterprises and the state encourage the use of bulk cement, the demand for bulk cement transportation is increasing. However, due to the large investment in fixed assets and seasonal fluctuation of transportation demand in bulk cement transportation, cement enterprises are faced with problems such as high transportation cost and low service level of bulk cement. Based on this background, the purpose of this paper is to reduce the transportation cost, make reasonable use of the vehicle resources and guarantee the service level from the angle of cement enterprises. This paper focuses on the optimal configuration of bulk cement vehicles in cement enterprises. Firstly, from the policy environment of bulk cement logistics development, The present situation of bulk cement vehicle configuration is analyzed in three aspects: the characteristics of distribution vehicles and the common vehicle configuration methods. On this basis, the "self-made / purchased" decision-making analysis matrix is used. This paper analyzes the formation and advantages of the mixed vehicle configuration of "self-owned vehicles" in cement enterprises. Secondly, according to the characteristics of bulk cement transportation and the actual situation of vehicle optimal allocation, the three main influencing factors, including bulk cement transportation demand, are analyzed. The market conditions and operating costs of both self-owned and self-employed vehicles affect the optimal allocation of bulk cement vehicles together. Finally, based on the analysis of the influencing factors of the optimal allocation of bulk cement vehicles, the optimal allocation models of bulk cement vehicles with the minimum total transportation cost under non-contractual constraints and strategic cooperation agreements are established respectively. Finally, the model is verified and analyzed by the actual case of "optimal configuration of bulk cement vehicles for JD cement", which provides guidance for the optimal configuration of bulk cement vehicles in cement enterprises.
