Preceding the 4GD concept, designers were often constrained by working with a predetermined top-to-bottom assembly structure. 4GD provides a more flexible model for working with product data where you can integrate specific structural sets for each design task and concurrently change and work on them without locking the overall assembly structure.
Designing the products used in the marine industry is a very competitive cycle that calls for complex information management systems for survival. Safer, cleaner, and greener ships, marine structures, and new energy sources require a completely new approach.
Engineering redesign and production processes, automation, and lean production are meant for responding to the design requirements of large ships with unique capacities using PLM systems.
