    Abstract: This research aimed to study the Improved Differential Evolution (IDE) for solving the Multi-floor
Facility Layout Problem (MFLP) with the target of minimize the transporting material costand maximize
adjacency requirement between the facilities. The IDE algorithm had been evaluated and compared with
MULTIPLE, SABLE and the basic DE algorithm by using DE/rand/1/bin and DE/rand/2/bin. For MFLP, the
IDE methods were tested with 6 data sets as following: 11-1, 11-2, 12, 21-1, 21-2, 21-3 which found that IDE
able to find the optimal solution better than the multiple is 52.67, 14.02, 15.89, 32.10, 20.01 and 36.92% for
problems 11-1, 11-2, 12, 21-1, 21-2 and 21-3, respectively and can generate the optimal solution that is better
than the sable is 6.75, 15.85, 2.76 and 27.56% for problems 11-1, 21-1, 21-2 and 21-3, respectively. The result
showed that the further performed IDE were effective methods comparing to the other algorithms and other
metaheuristic methods. Hence, they could be used to solve MFLP.
