Summary:总结中国原油采购-远洋运输业务流程,分析原油采购-远洋运输方案优化问题的特殊属性。原油采购-远洋运输方案优化是包含多种高维度变量的动态-模糊组合优化的大规模NP(non-deterministic polynomial)难问题,需要多个区域业务人员根据市场和需求的动态变化协作完成,超出现有方法的解决范畴。提出模糊聚类图优化法,通过实时挖掘和利用启发性优化信息以及全局视野拼接由启发式算法所搜索到的局部静态优化方案,实现大规模原油采购-远洋运输方案的全局优化。应用结果表明,模糊聚类图优化法弥补了传统建模求解的方法的不足,充分结合了人的灵活决策优势与计算机暴力计算特点,可辅助业务人员适应原油采购-远洋运输方案优化的动态-模糊特性,通过合理调整运输任务(即调整优化模型的目标函数和限制条件)实现原油采购-远洋运输方案优化,具有较强的决策支持作用。
Bibliography:The procedure of purchase & ocean shipping of crude oil in China was summarized,and the characteristics in opti-mizing the procedure were analyzed. The optimization can be categorized in a dynamic-fuzzy NP(non-deter^ninistic polynomi-al )hard problem involving the optimization of multidimensional variables,which needs to be dealt with by the cooperation of staffs coming from different areas,and is thus beyond the solving ability of existing optimizing algorithms. A vague cluster graphical method was put forward. By discovering and utilizing of heuristic optimization information in real time,and by utili-zing global view to joint local static optimized schemes searched by heuristic optimization algorithms, this method achieved the goal of global optimization. The vague cluster graphical method for optimizing of purchase & ocean shipping schemes of crude oil,coving the shortage of traditional model solving and taking the advantages of the combination of human interaction and computer's ability for brutal calcul
