STK
针对STK（Satellite Tool Kit）软件在军事任务可视化仿真领域中的广泛应用，为充分挖掘
其显示潜能，重点解决了影响其三维场景构建的瓶颈问题，即三维场景数据格式的转换和数据的获取
优化。在分析构建STK 三维场景所需要素及其作用的基础上，分别对地形、地表纹理、三维模型和GIS
等四类数据格式进行分析，并利用多种辅助软件，系统地提出了由较通用格式数据向STK 所支持格式
数据的转换方法，以及在对各类原始数据的获取和转换过程中出现的问题进行处理的优化方法。最后通过实例验证表明该数据格式转换方法和数据优化方法行之有效，三维场景显示效果逼真。(STK (Satellite Tool Kit) software widely used in the field of military tasks, visual simulation, to fully tap its display potential, focus on resolving the bottlenecks that affect the construction of the three-dimensional scene, 3D scene data format conversion and data Get optimization. On the basis of the required elements and their role in the analysis of building STK three-dimensional scene analysis, respectively, of the four types of terrain, surface texture, three-dimensional model and GIS data format and use a variety of assistive software, the system proposed by the more common format The data support the format of the data to STK conversion method, as well as access to various types of raw data and conversion process issues deal with the optimization method. Finally, an example to show that the data format conversion method and data optimization method is effective, realistic three-dimensional scene display.)

煤矿节能减排多目标优化研究
针对传统煤矿节能减排优化模型选取的目标函数比较单一的问题,构建了涵盖经济效益、能源消耗、污染物排放量等目标函数的煤矿节能减排多目标优化模型,并应用基于改进的蝙蝠算法寻找3个目标函数之间的优化解,实现了经济效益最大化、能源消耗最低化、污染物排放量最少化的优化结果。仿真结果表明,相比于PSO-E、NSGA-II算法,改进的蝙蝠算法能够在较短的迭代步数内获取较高的个体适应度,且能够实现较佳的多目标优化结果,符合节能规划的目标需求。(Aiming at the problem that the objective function of the traditional coal mine energy saving and emission reduction optimization model is relatively simple, the multi-objective optimization model of coal mine energy saving and emission reduction is constructed, which covers economic benefit, energy consumption and pollutant emission. And the optimized solution is used to find the 3 target functions based on the improved bat algorithm, and the economy is realized. The optimization results of maximizing efficiency, minimizing energy consumption and minimizing pollutant emissions are achieved. The simulation results show that, compared with the PSO-E and NSGA-II algorithms, the improved bat algorithm can obtain higher individual fitness within a shorter iteration step, and can achieve better multi-objective optimization results, which is in line with the target demand of energy saving planning.)
