Abstract
The productivity improvement is indispensible to shipbuilding industry for maintaining the world's No. 1. Simulation based production recently has been an issue as prat of efforts to high efficiency production and Korean shipyards requests simulation system tools specialized in a shipbuilding industry. IT convergence project between conventional shipbuilding industry and IT simulation technology has been carried out and integrated simulation framework was proposed as a way to overcome sporadic developments. The framework would provide reusability of kernels and modules and also ensure for expansibilities to other production simulations. The fact that production simulation system should reflect shipyard requirement would be most important. We suggest an analysis process of customer requirements and functional requirements for production simulations. It is partially based on concepts of software engineering and axiomatic design. The process is applied to a design of configuration for simulation framework.
