Due to the high land costs and limited areas, the use of multi-storey facilities is quite common today. However, considering the total transport costs, the multiplied distance and the workers’ movements, the importance of which floor of the parts within the facility will be assigned and the locations within the floor. The problem in which sections will be assigned and their locations within the floor are defined as the multi-storey facility settlement problem (CKTYP). The number of elevators, the location of the elevators, the number of floors, the number of sections, etc. The decision variables increase the complexity of the CKTYP and make it more difficult to resolve. In this study, a method is proposed consisting of two stages for the solution of CKTYP. In the first phase of the suggested algorithm, sections are assigned to layers, while in the second phase, the Benders separation algorithm is used to determine the locations within the layers to minimize the total transport costs between the sections. The contribution of the study to literature is that the Benders separation algorithm was first used in this study for the solution of CKTYP. The suggested Benders separation algorithm has been tested on 4 issues taken from literature. In this study, three large-scale problems adapted to CKTYP have also been solved. When the results were examined, the suggested Benders separation algorithm found that costs improved by 0.1234 to 5.3385 per cent for the 4 issues derived from literature.
