Description

Simulation Method of Shipyard Work Processes The present invention relates to a method for simulating a shipyard work process for simulating work time in a shipyard work process. Sub-assembly refers to the process of assembling small blocks before assembling the ship's large structural components at a shipyard. Shipbuilding at shipyards utilizes a modular construction method, where the ship's structure is manufactured by dividing it into multiple small blocks, which are then reassembled to complete the hull. Furthermore, sub-component work is part of the sub-assembly process, which involves fabricating and preparing small, detailed components before assembling the ship's large blocks or structures. The sub-components produced at this stage are individual parts required for assembling sub-blocks, serving as the small units that form the basis of shipbuilding. When introducing new welding techniques or automated welding equipment into shipyard processes, it is necessary to analyze not only the effectiveness of individual welding operations but also their impact on overall process productivity. Shipyard in-house workshops involve a complex interplay of diverse logistics flows via cranes and mobile workbenches, and it is common for multiple welders to perform various processes simultaneously. Therefore, it is essential to analyze the actual effectiveness of automation rates or improvements in individual welding operations from a factory-wide perspective. Analyzing productivity from a factory-wide view allows for the identification of return on investment in advance, thereby enabling the detection of investment risks.
