双层

Finally,a simple simulation application was illustrated,by analyzing and comparing of the result,when subcontract supplier selection is long-term and it is carried out repetitiously,the method is good at inspiriting subcontract supplier to cut down price and improved service quality at the same time.

最后，利用一个简单的实例进行试验，结果分析和比较表明，当分包商选择是长期的且分阶段多次进行时，该双层规划模型能很好的激励分包商提高服务质量，降低分包价格。

In addition, the new Duplicate Page command gives users the flexibility to copy a page with all objects included or just the layer structure, making it easier to repurpose existing designs.

此外，新的重复页的命令使用户能够灵活地复制页面，所有对象包括或仅仅是双层结构，使其更容易重新利用现有设计。

A two-layer framework with particle swarms cooperative optimization and a mutation parameter is introduced by the QPSCO algorithm for larger searching scale and quicker convergence. Moreover I the residual sum of squares in least-square principle is introduced into the fitness function to enhance the fitting precision of the sensor position curve.

在QPSCO算法中，采用双层的多粒子群协同优化结构，同时引入参数变异策略，在扩大搜索范围的同时加快该算法收敛；将加权最小二乘法的误差平方和引入适应度函数中，以提高传感器位置曲线的拟合精度，从而实现传感器的优化配置。

The simulation result indicated that the double-layer spherical reticulated shell the active control effect is obvious.
