An approach for integrating quality management methods with CAD-systems in ship detail design

For the detailed modelling of ship structural components CAD-systems are applied to build a ship product data model. To ensure the correctness of the design data numerous quality criteria have to be observed. Neglecting those criteria deteriorates the production productivity. Nowadays, the final inspection of the design data is almost manual. In this paper quality criteria being addressed are those applied for an optimised ship structure production process like requirements with respect to the weldability in ship structure assembly processes. To support the efficient correction of deficient structural designs an approach is presented which allows the correction of faulty structures under visual guidance towards the identified problems applying the same CAD system as used for the product model data generation. The so-called error-feedback allows the engineers to detect and fix the automatically detected errors in the design data. This will result in significant time savings in the production phase.
