For an energy-efficient induction machine, the life-cycle cost (LCC) usually is the most important index to the consumer.
With this target, the optimization design of a motor is a complex nonlinear problem with constraints. To solve the problem,
the authors introduce a united random algorithm. At first, the problem is divided into two parts, the optimal rotor slots
and the optimization of other dimensions. Before optimizing the rotor slots with genetic algorithm (GA), the second part is
solved with TABU algorithm to simplify the problem. The numerical results showed that this method is better than the method
using a traditional algorithm.

对于报刊资料信息开发的见解与方案 总被引:1,自引:0,他引:1
一、总体设想 报刊部是我馆工作最繁杂的一个部,既有基础业务工作,也有信息开发工作.基础业务工作千头万绪,集采、编、阅、藏于一体,各种不同文献类型面临的问题也是千差万别.各个科组本身就是一个相对独立的小图书馆,业务复杂程度大大超出一般科组,繁重的创收任务更是各科组的沉重负担.这样的科组划分使得各个科组既无法专心研究业务,也不能一心一意地进行报刊信息的二次开发,实际操作中往往是顾此失彼,对报刊部整体的长远发展极为不利. 相似文献
