【摘要】：经济发展全球化不仅推动了国际工程市场繁荣,同时也带动国际工程物流的发展。国际工程物流是为大型的电力、石化、冶金等建设项目服务而产生的,以大宗货物跨国运输为主要平台的所有物流活动。国际工程项目物流是以满足大型建设项目的进度计划和控制过程为服务目的,为这些项目提供大型货物或成套设备的跨国物流方案。国际工程物流具有涉及的物流环节多、规模大、参与方多、技术水平要求高等特点。因此,国际工程物流对于国际工程能否顺利竣工起着关键的作用。物资的采购和库存管理是国际工程物流运作的关键,影响着国际工程的工期、质量和成本。首先,本文在对国际工程物流的特点及运作流程进行分析的基础上,对国际工程物资采购的特点和流程进行了论述。在对供应商管理库存、联合库存管理以及协同库存管理3种库存管理模进行了对比分析后,将联合库存管理应用于国际工程库存管理中。其次,针对国际工程采购模式、采购组织结构以及供应商管理的现状和存在的问题,提出了多源采购向单源采购转变、多向网络信息传递机制、建立动态采购中心以及对供应商进行分类管理等优化策略,有效提高了采购的效率。最后,应用遗传算法对国际工程联合库存优化模型进行求解。并将模型应用与国际工程实例中,通过与传统优化模型的对比,证明了优化模型可以有效降低供应商和施工方的库存成本。
[Abstract]:Economic globalization not only promotes the prosperity of international engineering market, but also promotes the development of international engineering logistics. International engineering logistics is for the large-scale electric power, petrochemical, metallurgical and other construction projects and services generated, with the bulk of the international transport of goods as the main platform for all logistics activities. International engineering project logistics is a transnational logistics scheme which provides large-scale goods or complete sets of equipment for these projects for the purpose of meeting the schedule and control process of large construction projects. International engineering logistics is characterized by many logistics links, large scale, many participants and high technical level. Therefore, international engineering logistics plays a key role in the successful completion of international projects. Material procurement and inventory management is the key to the operation of international engineering logistics, which affects the duration, quality and cost of international projects. Firstly, on the basis of analyzing the characteristics and operation process of international engineering logistics, this paper discusses the characteristics and flow of international engineering material procurement. After comparing and analyzing three kinds of inventory management models: supplier managed inventory, joint inventory management and collaborative inventory management, the joint inventory management is applied to international engineering inventory management. Secondly, aiming at the current situation and existing problems of international construction procurement mode, procurement organization structure and supplier management, the paper puts forward the transformation from multi-source procurement to single-source procurement, and the multi-direction network information transmission mechanism. The efficiency of purchasing is improved by establishing dynamic purchasing center and classifying suppliers. Finally, genetic algorithm is applied to solve the joint inventory optimization model of international engineering. By comparing the model with the traditional optimization model, it is proved that the optimization model can effectively reduce the inventory cost of suppliers and builders.
