针对优化规划城市公交线路网络布局问题,提出了一种以公交线路可达性为原则并基于蚁群算法的城市公交路线网络布局优化模型.首先将公交线路分为快线、普线和支线,分别建立目标函数模型及约束条件,然后引入蚁群算法对目标函数进行优求解,最后利用实例对以上方案进行验证.结果 表明,构建的模型具有一定程度上的优化能力,可实现不同层面线路的优化.本研究的创新点在于从不同角度对公交线路进行优化,以此提高了线路的可达性,更好地提升了公交企业的服务水平.

Sampling-based path planning is a popular methodology for robot path planning. With a uniform sampling strategy to explore the state space, a feasible path can be found without the complex geometric modeling of the configuration space. However, the qualit
Nonlinear equations systems (NESs) are widely used in real-world problems and they are difficult to solve due to their nonlinearity and multiple roots. Evolutionary algorithms (EAs) are one of the methods for solving NESs, given their global search capabi

设备故障停机时长是影响企业生产运营和效率的关键技术指标.为了能一目了然地反映设备自身的运行状况,提出了一种设备故障时长评估新指标——设备故障工时损耗率,将因设备故障产生的时长转化为设备故障工时损耗率.以露天矿大型设备电铲车一年电气故障时长作为基础数据,建立均值差分GM(1,1)模型,掌握设备稳定性,为采矿优化调度、生产产能制定提供有效支撑;建立ARIMA模型,拟合时间序列并获取短期预测数据,将其转化为评估指标验证模型,有效缩短故障检测和维修准备的时间.

常规同步控制建模过程中,同步控制全从方案与约束事件触发机制不匹配,导致同步控制建模的控制触发时刻和间隔不理想,针对这一问题研究全新的非对称耦合网络,阵列信号传输过程同步控制建模方法.根据AIN框架组图,确定非对称耦合网络的混合相变;按照一定顺序性和规律性设计同步控制全从方案,建立模型同步控制算法;结合非对称耦合网络饱和状态,设置具有饱和约束的事件触发机制,建立阵列信号传输同步控制模型.仿真实验建立非对称程度不同的耦合网络,发现在模型同步控制过程中,所设计模型得到的信号传输轨迹更贴切,模型的同步控制触发时刻
