传感器网络
传感器网络由大量能量有限的微型传感器节点组成.因此,如何保证在足够覆盖监测区域的同时延长网络的寿命,是一个需要解决的重要问题.为了达到这一目标,一种广泛采用的策略是选出部分能够足够覆盖监测区域的节点作为工作节点,同时关闭其他冗余节点.提出了一个数学模型,使得只要已知监测范围和节点感知半径的比值,就可以计算出达到服务质量期望所需要的节点数量.需要指出的是:与大部分研究覆盖的文献不同,该研究不基于节点的位置信息,因此可以极大地降低硬件成本,并且减少节点获得和维护位置信息的开销.模拟实验结果表明:在随机部署条件下,服务质量期望与实验所得到的实际覆盖度的误差不大于服务质量期望的2％ 而对于相同的服务质量期望和实际覆盖度,计算所得的工作节点数量与实验所得的工作节点数量的误差小于计算数量的5％,这表明推导出的节点数量与服务质量期望之间的关系与模拟实验的结果相吻合.该结果可以广泛应用于传感器网络的节点部署、拓扑控制等领域中.()

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.)
