This research presented the use of the Differential Evolution (DE) method to solve the problems of finding location and routing logistics. Cases of oil palm bunch collection centers and palm logistics in Narathiwat province were studied. Oil palm extracting factories had to consider selection of the oil palm bunch collection centers opening in 77 sub-districts, Narathiwat province to minimize the capital costs of finding location and routing logistics. The factors considered were the location of the oil palm bunch collection centers and the distance from oil palm agricultures to the oil palm bunch collection centers. Then, the differential evolution method was applied to solve the problem of the capital cost. This method was used because the differential evolution method was popular and it was easy and fast to find the result. The mutation process which was the most important process was developed by using the 3 mutation process equations. The new mutation was obtained; the results were different from and better than the previous ones. Then, the swap process was used in order to gain more efficient results. The finding revealed that the Differential Evolution by using the process of mutation which offered the lowest cost was 3,786.50 baht per day. The research finding also showed the 39th oil palm bunch collection center within 675.10 kilometers. More importantly, there were 13 logistics routes.
