第22届多国仪器仪表学术会议暨展览会见闻与观感

介绍了MICONEX2011概况,并就其主题、组织工作、受金融风暴的影响、交流平台、有新意或有特色的展品、环保与节能、"十二五"重点行业的需求、企业文化的重要性以及劳动密集型产品的无序经营共十个方面进行点评,最后发表了三点观感。即要重视基础理论的研究,产学研与用的结合和需要展开后DCS时代的讨论和云控系统CCS的可行性。

终端区进场流的路径选择研究

在实际运行中,通常依据管制员的经验对进场航班流的路径进行管理,缺乏科学性。针对终端区进场流的路径选择与进场排序的流量管理问题,以进场航班的总完成时间最短为目标,建立基于时间窗与位置约束的路径选择与排序的数学模型。采用先选择路径再排序的循环寻优的方法进行求解,将禁忌搜索(TS)与排序算法相结合,设计了TS-FCFS与TS-DP两种算法,着重建立了基于关键路径的邻域结构,并加入有效的重置(RESTAR)策略,使算法快速有效的收敛至最优解。最后借助SIMMOD仿真平台验证算法的可行性。以北京首都机场21架航班为例,仿真结果显示,TS-FCFS与TS-DP两种方法较原计划的进场路径总完成时间分别节约了149s与175s。该路径选择算法降低了进场时间,提高了终端区进场效率。通过合理优化进场航班流的路径选择与进场排序,平衡了跑道负荷,减少了航空器间潜在的冲突,同时为管制员调配进场航班流提供了合理有效的路径选择建议。

A Study of Power Sources Optimization in Guangdong

The main problem existing in Guangdong electric power sources is analyzed in this paper. Based on theanalysis on energy-supply features, power demand and the technical and economic performances of various powersources in Guangdong, the power sources construction scale and its structure are studied and analyzed in detail byusing Generation Expansion Software Package (GESP). The future development of Guangdong electric power sourcesunder the new situation of "Power from West to East" is studied as well.[
