A Systematic Layout Planning and TOPSIS Application for the Design of a Power Generation Turbine Parts Repair Workshop

Objective: This paper presents a joint application of systematic layout planning (SLP) and TOPSIS methods for the facility layout design of a power generation turbine parts repair workshop. The SLP method is an easy-to-apply tool that can consider both qualitative and quantitative criteria. Materials and Methods: In this case study, the SLP method is adapted for a future plant project that is not currently in place. First, instead of a materials flow analysis, the definition of the process flow, as well as the department requirements, is carried out. Then, the closeness relationships between the process flow activities and the layout alternatives are determined. Finally, the TOPSIS method is applied to evaluate and select the best layout alternative according to the compliance with closeness relationships, the location of dangerous departments, the flow of operations, and the location of departments around a current electrical substation. Results and Discussion: The resulting facility design complies with the defined criteria, and its architectural and layout designs are presented using 3D software. Conclusion: The joint application of SLP and TOPSIS methods allowed us to obtain a proper facility layout design for the case of a power generation turbine parts repair workshop.
