【摘要】：受石油资源紧缺、价格上涨、全球气候变化的影响,世界各国都在大力推广生物能源的开发和利用,生物燃料是生物能源的重要内容,尤其是以谷物秸秆等非粮作物为原料的第二代生物燃料,其原料来源广泛、成本低廉、清洁环保,具有非常好的地域适应性、经济性和环境友好性。燃料乙醇可以直接替代车用燃油,引起了汽车消费大国以及农业大国的广泛兴趣,其市场潜力巨大。巴西、美国、欧盟等,在开发和利用燃料乙醇领域走在了世界前列,提供了许多有价值的经验。为了保证生物燃料能够持续供应,构建一个有效、稳定的生物燃料供应链网络是必不可少的。现有相关研究大多基于确定性环境,然而在实际运营中,除了供应、需求或价格等不确定性因素会给供应链网络带来运营风险外,诸如地震、飓风、爆炸、罢工等可能引发供应链失效的事件是普遍存在的,此类失效事件虽然发生的概率很小,可一旦发生,很可能对供应链系统造成重创。因此,为有效应对包括一般运营风险和失效风险在内的复杂风险环境,必须在生物能源供应链网络设计之初就充分考虑以上风险因素,使供应链网络既能够在常规状态下有效运作,又能够在面对失效事件的冲击时具有快速恢复到正常供应能力的弹性。本文秉承弹性供应链网络的设计理念,构建了一个主要由生物质产地、生物乙醇精炼厂和燃料乙醇需求中心组成的生物能源供应链网络,综合考虑了燃料乙醇需求不确定性的一般运营风险和生物质供应地及乙醇精炼厂的失效风险,对面向复杂风险环境的弹性生物能源供应链网络的设计与运作策略问题进行了研究,主要研究工作如下：(1)阐述了研究背景和研究意义,并给出了全文的逻辑思路、基本研究内容和结构框架。(2)对相关理论和文献进行了概述和总结。主要对生物能源相关概念、供应链风险和弹性供应链相关理论进行了介绍,又进一步对国内外生物能源供应链、供应链风险管理、弹性供应链以及供应链网络优化建模方法的相关研究进行了综述。(3)分别建立了不同优化目标下的生物燃料弹性供应链网络设计模型。首先,建立了面向复杂风险环境的弹性生物能源供应链网络优化设计模型,在此基础上,又进一步考虑了权衡系统服务水平与成本水平的弹性生物能源供应链网络设计模型。(4)算例分析。在前面有关内容研究的基础上,通过算例验证了模型的可行性与有效性,并证明了优化模型对弹性生物能源供应链构建的实际应用价值。(5)在文章的最后,总结全文内容,给出研究结论与不足,并提出下一步的研究展望。
[Abstract]:Affected by the shortage of petroleum resources, rising prices and global climate change, many countries in the world are vigorously promoting the development and utilization of bioenergy. Biofuel is an important part of bioenergy. Especially the second generation biofuel, which uses non-grain crops such as grain straw as raw material, has a wide range of raw materials, low cost, clean and environmental protection, and has a very good regional adaptability. Economy and environmental friendliness. Fuel ethanol can be used as a direct substitute for vehicle fuel, which has aroused widespread interest in large automobile consuming and agricultural countries, and has great market potential. Brazil, United States, European Union and so on. In the development and use of fuel ethanol in the field of the world's leading, providing a lot of valuable experience. In order to ensure a sustainable supply of biofuels, to build an effective. A stable biofuel supply chain network is essential. Most of the existing studies are based on deterministic environments, but in practice, in addition to supply. Uncertainties such as demand or price bring operational risks to supply chain networks, such as earthquakes, hurricanes, explosions, strikes and other events that may cause supply chain failures. Although the probability of such failure is very small, once it occurs, it is likely to cause heavy damage to the supply chain system. Therefore, to effectively deal with the complex risk environment, including general operational risk and failure risk. The above risk factors must be fully considered at the beginning of the design of bioenergy supply chain network, so that the supply chain network can operate effectively in the normal state. In the face of the impact of failure events can quickly restore to the normal supply capacity flexibility. This paper adheres to the design concept of elastic supply chain network and constructs a biomass production area. The bioenergy supply chain network composed of bioethanol refineries and fuel ethanol demand centers takes into account the general operational risks of fuel ethanol demand uncertainty and the failure risks of biomass suppliers and ethanol refineries. This paper studies the design and operation strategy of flexible bioenergy supply chain network facing complex risk environment. The main research work is as follows: 1) the research background and significance are expounded. At the same time, the logical thinking, basic research content and structure framework of the whole paper are given. The related theories and literatures are summarized and summarized. The related concepts of bioenergy are mainly discussed. Supply chain risk and elastic supply chain theory are introduced, and further domestic and foreign bio-energy supply chain, supply chain risk management. This paper summarizes the research of elastic supply chain and supply chain network optimization modeling methods. (3) establish different optimization objectives of biofuel elastic supply chain network design model. First of all. The optimal design model of elastic bioenergy supply chain for complex risk environment is established. Furthermore, an example analysis of flexible bioenergy supply chain network design model based on the balance between system service level and cost level is given. The feasibility and validity of the model are verified by an example, and the practical application value of the optimized model to the construction of elastic bioenergy supply chain is proved. 5) at the end of the article, the content of this paper is summarized. The conclusion and deficiency of the research are given, and the future research prospect is put forward.
