초록
Outfittings of offshore plants and high value-added vessels, such as FPSO, drillship, are much more than outfittings of general ships. So the complexity of the outfittings is increased and the importance of outfittings has also increased. But, there is no clear method to define the installation sequence of outfittings, yet. In this study, we developed the algorithm to define the installation sequence of outfittings by applying variables and constraints related to outfitting, such as process parameters, weighting coefficients, installation constraints. Also, we developed the application that applied the algorithm and compared cases by changing the weighting coefficients of process parameters. We verified the practicality of the algorithm by developing the application. The results of this study are that the accuracy of the outfitting planning is improved and efficient lead time can be predicted by defining the installation sequence of outfittings.
