摘要
针对建设项目投资方案决策问题,采用高维降维技术——投影寻踪分类模型(PPC),利用基于实数编码的加速遗传算法(RAGA)优化其投影方向,将多维数据指标(样本评价指标)转换到低维子空间,根据投影函数值的大小评价出方案的优劣,从而做出决策,取得了满意的效果,为建设项目投资方案决策及其它评判决策问题提供一条新的方法与思路。
Through applying PPC model base on RAGA in the investment plan of building project decision - making,the author turn multi - dimension data into low dimension space.So the optimum projection direction can stand for the best influence to the collectivity.Thus,the value of projection function can evalu- ate each item good or not,and obtain better result. The authors want to provide a new method and thought for readers who engaged in investment decision- making of investment plan of building project and other relation study.
