Embodiment Construction
[0144] The present invention will be further described below in conjunction with the accompanying drawings.
[0145] Assume that the number of subsidiaries M of the logistics company is 3, the vehicle load C=100, the total order N is 150, the population size P is 100, and the mutation probability is p m is 0.1, the maximum iteration algebra g is 200, α=0.6, β=1.4.
[0146] Step 1: Order Redistribution
[0147] Step 1.1: let i=0;
[0148] Step 1.2: Calculate the distance ratio a of order i respectively 12 , a 13 , a 23 ;
[0149] Step 1.3: Judgment
[0150] if a 12 ≤0.6 and a 13 ≤0.6, the order i is assigned to subsidiary 1, and the order i is added to the set S 1 ;
[0151] if a 12 ≥1.4 and a 23 ≤0.6, the order i is assigned to subsidiary 2, and the order i is added to the set S 2 ;
[0152] if a 13 ≥1.4 and a 23 ≥1.4, then order i is allocated to subsidiary 3, and order i is added to set S 3 ;
[0153] If the above is not satisfied, add the order i to the fu...
