The National Shipbuilding Research Program. Proceedings of the IREAPS Technical Symposium, Paper No. 3: CASA: A System for Computer Aided Ship Accommodation
Abstract
The Computer Aided Ship Accommodation (CASA) system is very advanced in the field of automatic design. CASA has been planned for the production of drawings of high graphic quality, the relevant bill of material, and the preparation of the workship documentation. The system uses interactive graphic techniques to facilitate both the man-machine communication and to increase the throughput and flexibility of the programs. CASA has three main modules: (1) Description of standards is handled in batch mode. In this case the input concerns standard materials description and general selection rules. These data are stored into the database of the system; drawings and lists are also provided. (2) Description of ship design data. From structural drawings the main data are loaded into the computer for further processing. All the operations of this phase are considerably simplified (thanks to a particular "user-oriented" language) and do not require specific knowledge of EDP. Relevant output drawing will constitute the basic layout of accommodation. (3) Interactive automatic design. From description of construction data and standards with the aid of interactive functions of CASA, "automatic" and "interactive" design are developed. Automatic design, which foresees data processing for each constructive detail, is completely handled in its initial phase in batch mode. Interactive design allows corrections and modifications of data and programs with immediate feedback, thus giving the operator the possibility of a quick and easy communication with the computer.
