Improved PSO layout optimization model for saloon cabin driven by users' decision making

Based on the users' decision making, groups and sequences of facilities position optimization were determined approximately, and facilities optimized determine positions of which were not optimized. The PSO was adapted to develop a new method of saloon cabin layout optimization in 3D. To avoid obtaining partial optimal solutions, an improved PSO by adaptive inertia weight was used and the new method of layout optimization which might be adjusted according to different users' needs was proposed. The different optimized solutions were analyzed and compared to the original one by JACK, the results show the optimization method of the improved PSO is the best one and consistent with ergonomic principles. The method can solve the saloon cabin layout optimization problems effectively.
