Abstract: [Object] It is an object of the present invention to provide a shipbuilding simulation method and a shipbuilding simulation program based on a unified database capable of simulating building of a ship at detailed operation level.

Abstract: The present invention is to simulate building of a ship at a detailed operation level by executing: a product model creating step S1 of creating a product model by obtaining basic design information 1 in which a coupling relation between a completed part and a component part of the ship is clarified; a facility model creating step S2 of obtaining equipment information 21 and worker information 22 of a factory and creating a facility model; a process model creating step S3 of clarifying assembling procedure and tasks to build the completed part and creating a process model based on the product model and the facility model; a simulation step S4 to carry out time evolution system simulation based on the process model; and a time series informatization step S5 of time series digitizing a result of the time evolution system simulation into building time series information 42.
