The Facility Layout Planning (FLP) is a fundamental problem strongly influencing the overall productivity in the medium and long term. In case of shipbuilding industry, material handling costs account for a large part in total production costs due to its heavy and massive intermediate products. An optimized shipyard layout is essential for minimizing total production costs and increasing productivity.
The aim of this study is to optimize shipyard layout based on minimizing material handling costs in the construction of ships, considering irregular shipyard shape and unequal department areas. Adjacency and alignment requirements among departments are also considered. The optimization process consists of two stages： Topology and Geometry optimizations. In the topology stage, we determine the optimal centroid location of each department using Genetic Algorithm (GA). In the geometry stage, each department gradually grows while filling unoccupied shipyard space from the optimal centroid until it reaches to its designated size and shape, using Stochastic Growth Algorithm (SGA).
The practicality and the reduction of material handling cost are identified comparing the optimized shipyard layout based on proposed approach with real shipyard layout suggested by human layout expert.
