Long-Term Planning Optimization System for Strategic Contracting in Shipyard

In this paper, we propose a long-term planning optimization system for determining strategic contracting in a shipyard. The planning system mainly consist of an optimization model and the integrated system. The optimal long-term plans are established by the Constraint Programming based optimization model that reflect various constraints and objective functions. The integrated system is developed for data management, optimization model execution and result visualization. Performance and accuracy of the proposed system has been verified by comparing with a previously established plan in a SHI shipyard.
