Unlike other mass production in small variety, shipbuilding process is a project-based method in single variety, which causesunpredictable volatility in the planning system. In shipyards, series of manufacturing processes from fabrication to erection issequentially carried out. In order to predict unfavorable changes such as overload or low load of working volume, computerizedsimulation has been being gradually adopted. The data used in the simulation are processed from the database of the main schedulingand planning system. Thus the quality of those data is very crucial for the meaningful results. Unfortunately, research on the verificationof data quality is very rare and hardly known to the authors. In this work, using the database of scheduling and product informationsystem of a large domestic shipyard, the data required for the simulation are qualitatively analyzed and verified.
