Application of Layered Coding Genetic Algorithm in Optimization of Unequal Area Production Facilities Layout

Algorithm 1

Coding of facility population, splitting position and splitting mode layer.

	Input: Popu_size, n_f
	Output: F(facility population), Sp[Popu_size × n_f] (Splitting position string), Sm[1 × n_f − 1] (splitting mode string)
(1)	for I ⟵ 1 to Popu_size
(2)	F(i,:) ⟵ permutation of n_f integers valued from 1∼n_f;
(3)	Sp(i,:) ⟵ permutation of (n_f − 1) integer valued from 1∼(n_f − 1);
(4)	Sm(i,:) ⟵ permutation of (n_f − 1) number valued 1 or 0;
(5)	end for
(4)	Establishment of fitness function.
