In response to the phenomenon of long transportation distances and high transportation costs due to the current workshop layout, this paper proposes a layout optimization scheme based on the System Layout Planning (SLP) method, which is verified for feasibility through Flexsim simulation.In the optimization process, focusing on the two important factors that affect the workshop layout, namely transportation distance and transportation cost, a qualitative solution is proposed using a real case study as the research scenario.The results show that the optimized layout scheme can significantly reduce transportation distance and transportation costs, when compared to the original layout scheme.This case study provides reference and inspiration for workshop layout optimization, and also provides guidance for ship equipment manufacturing enterprises to achieve efficient production processes and cost control.
