A reliable advance planning and scheduling (APS) solution not only determines the assembly and erection of blocks but also the work schedule and spatial batch planning. The APS provides important information to support the management's decision-making process and drive the shipyard strategy. The quality of production planning determines the productivity of a shipyard. Using the right planning solution will enable shipyards to optimize ship delivery. Based on Dassault Systèmes' customer achievements, some of the largest shipyards experienced a 3% reduction in production buffer. This improvement helped the shipyards increase shipyard capacity, resulting in the ability to produce additional blocks of up to one ship annually for large shipyards. Additionally, planning efficiency increased by 30%.
