The establishment of a quay process plan for process efficiency is attracting attention as a major concern reflecting the changes of the times in the shipbuilding industry.

The dock/quay wall work plan for the shipyard is established according to the loading network schedule according to the ship list considering the various order lines and the block production plan for each line. .

In addition, as the production plan changes frequently due to numerous environmental variables in the shipyard yard, an integrated platform capable of deriving in advance the constraints and factors affecting the plan, and comprehensively analyzing and simulating the effective planning and actual field production performance. The need for is emerging. In addition, the dock/quay wall schedule management capability of mid-sized shipyards is dependent on schedule management using individual unit programs or spreadsheets due to the insufficient production information standardization system. there is a problem.
