优选法是利用数学方法以较少的试验次数,迅速地找到最优方案的方法。优选法分单因素和多因素两种方法。单因素法有平分法、0.618法、分数法、同时法和分批试验法(包括比例分割法和予给要求法)。多因素法有降维法(又叫折纸法,包括平行线法和纵横对折法)、调优法(包括矩形调优法和单纯形调优法)和瞎子爬山法等。优选法在汽车制造和汽车修理行业中也得到应用,并收到明显的效果。
The preferred method is the use of mathematical methods with fewer trials, quickly find the optimal solution. Optimization of the law of single-factor and multi-factor two methods. The single factor method is bisect, 0.618 method, fractional method, simultaneous method and batch test method (including the proportion of division method and give the request method). Multi-factor method has dimensionality reduction method (also called origami method, including the parallel line method and aspect ratio method), tuning method (including the rectangular tuning method and simplex tuning method) and the blind hill climbing method. The preferred method has also been applied in the automotive and automotive repair industries and has received significant results.
