3. Computational results
We generate 5 test problems with 3, 5, 7, 10 and 15 departments. Input data include material flow matrix and parameters cost. For dynamic approach, we consider 4 periods. We solve model using CPLEX 10.1 in a PC with 1.00 GB RAM and 2.4 GHz CPU. Table 1 and Table 2 show solution for static and dynamic multi floor facility layout problem.
