A real-coded genetic algorithm is proposed to solve the form evaluation of planes.According to the mathematical definition of dimensional and tolerancing principles
a mathematical model of flatness evaluation in accordance with the minimum zone condition is presented and the fitness function of genetic algorithm is given.Then the implementation steps of the algorithm are dwelt on. Based on the real-coded method
the genetic operation is composed of roulette wheel selection
real-valued simple crossover and uniform mutation.Finally the data in literature are verified by the proposed approach.The results show that the algorithm is superior to others in terms of efficiency and quality of solution in the field of dimension and tolerance evaluation.
