Abstract
This paper proposes a simulation technique for the shipbuilding process based on a multi-agent system. In this paper, we propose a simulation technique for the construction process based on a multi-agent system. In this method, the worker is regarded as an agent and the virtual factory as an environment. Tasks are represented as a combination of more detailed elemental tasks. Three techniques, pathfinding with the A-star algorithm, placements of two-dimensional irregular shapes, and intersection with other equipment or occupied areas, were introduced to allow agents to take spatial constraints into account. It also simulates the manufacturing process by performing task selection through an evaluation function based on weight coefficients. The simulation results for sub-assembly and assembly process in a real shipyard confirmed that the task could be reproduced with high accuracy. It is possible to capture manufacturing features in simulation in advance, without manufacturing them.
