中文摘要： 煤炭供应链的规划和运作是非常复杂的系统行为：系统的有效容量取决于各子系统的相互作用结果；作用于不同时间跨度的短期、中期、长期等规划和调度需要协调和衔接才能保证各阶段决策的正确和有效。最大效率地利用煤炭资源，需要动态配煤，即将正确的原材料在正确的时间送到正确的地点生成配煤产品，从而最大程度地满足客户需求。针对这些复杂性，本项目为煤炭供应链建立端到端的优化模型，将系统作为一个整体统一运作。本研究通过对时间粒度的控制，确定不同时间跨度下决策模型的充分必要精细度；基于对偶性理论和分解算法探索新的方法，将铁路等复杂子模块融入端对端的主系统模型以简化优化模型结构；设计和开发集中约束规划、数学规划和局部搜索等算法优势的混合优化算法，对模型求解。本项目的研究成果对煤炭供应链精益、高效地管理有重要的理论和实践意义。

英文摘要： Coal is one of the essential resource supply in China, and is responsible for up to 70% energy consumption of the nation. Our coal production is about 3.5 billion tonnes in 2011, which is more than 40% of the world's total production for that year. But, there are issues: tradinationally, coal producing companies are mostly small-scaled and scatterly located; coal logistics is difficult to manage and is lack of efficiency which is not only because of the lack of rail capacity but also because of the complexity of the underlying system; and coal product is not fully utilized and low quality coal is often wasted. These problems result in an unhealthy development of China's coal industry. Researchers from the coal chain area presented the idea of end-to-end coal chain, which is trying to connect all intermediate processes ranging from the production end to the consumption end of the coal. The end-to-end coal chain enbales allocation of resource and coordination between partners in a global and optimal way and makes the management to be service-oriented other than product-oriented. Early practitioners even received financial benefits from doing business by following this idea. Recently, the government also issued a series of polices and carried on a set of plans to show the national support of the development of coal supply chain in this direction. However, making decisions on coal chain operations is not easy. The system is large and complicated, and information is often fragmented and available only to its own section. Furthermore, procedures on the chain are interacted: optimizing one doesn't make the system succeed as a whole. In this project, we plan to optimize the integrated coal chain with mathematical methods which include modelling the coal chain operations from end-to-end either in a long term or whitin different time granularities, and developping advanced algorithms, especially the hybridized optimization methods to solve the models. We aim to develop intelligent computer based system to assist the management team in making better decisions on, for example, capital investment, collaboration polices or operaional plans; and we aim, for more important, to advance mathematical modelling and computing approaches in applications of coal supply chains.
