Computational Shipyard Dynamics

Early simulations focused mainly on virtualizing the shipyard itself and the approach in terms of production management that focuses on improving productivity was hardly sufficient. For systematically approaching shipyard production problems, to which the dynamics between various factors are applied, this study uses the shipyard simulation information model to explain the six factors, which are the input variables of the shipyard production system simulation. Then, the objective or output variable is set up as the key performance index (KPI) by aligning the interests from an enterprise perspective. The output variable, KPI, is generally expressed as a function of functions of the input variables, namely a functional. To evaluate the value of the functional, a computational method in the form of a simulation is used. The process-centric simulation is adopted as it is appropriate for the shipyard production system simulation, which is an engineered-to-order industry, and it is easy to implement the concept of dynamic resolution. According to this methodology, we present a simulation application that focuses on the fabrication shop of a shipyard.
