摘要
研究了光网络流量工程优化计算中的适应度函数,其实质是为相互制约的多个单目标寻找一个合理的综合评价的数学表达式。使用了主分量分析的方法,该方法可以消除多个单目标之间的相互制约的关系、信息重叠以及量纲的差异,可以计算出综合评价的有效的数学表达式。仿真试验表明,该方法是可行的。
This paper focuses on the fitness function of traffic engineering optimum calculation in optical networks, whose essential is to find a reasonable mathematical expression of comprehensive estimation for many interrestrictive single objects. Principal Component Analysis is used, which can eliminate the interrestriction of the object, clear up the information superposition, and avoid the difference of dimension, to obtain the efficient mathematical expression of comprehensive estimation. Simulation testifies the feasibility of this novel method.
