提出了一种有效和通用的模型——投影寻踪分类模型。采用基于实码的加速遗传算法寻找最优的投影方向,同时用投影方向信息研究了各因子对我国造纸工业经济效益评价的影响水平,取得了符合客观实际的分类结果。
In order to increase the distinguishability of the model for integrative evaluation of economic benefits of Chiua's paper industry, an effective and general model-PP(Projeetion Pursuit)model was presented. The Accelerating Genetic Algorithm based on Real Coding was adopted to find the optimum projective direction, at the same time, the data of the optimum projective direction were used to study the level of the influence of various factors on the evaluation of economic benefits of Claim's paper industry. The classification results which accord with the fact were gained, which provide the decision base for further raising the economic benefit of Chiua's paper industry.
