Feasibility Model of CASDAC Level IV/V Top-Down Analysis.
Abstract
This study defines the 'top-level' functional structure of CASDAC (Computer-Aided Ship Design and Construction) Level IV/V. The definition is accomplished by using a hierarchically structured modeling technique to examine the top levels of each of the six individual functional systems which have been identified as the principal components of CASDAC Level IV/V. These six functional systems address the following areas of ship design and construction: Hull (HULDAC); Machinery (CAMDAC); Piping (CAPDAC); Electrical/Electronic (ELXDAC); Heating, Ventilation, and Air-Conditioning (CAVDAC); and Handling (HANDAC). The study was restricted to the top three functional levels from a total potential of perhaps ten levels. The study identifies the areas of responsibility of the individual functional systems, identifies data within these systems, and examines the interfaces between the detail design functional systems and Level III subsystems. Data were gathered, organized, and presented for each of the functional systems using the Hierarchical Input Process Output (HIPO) methodology. These HIPO diagrams comprise the core of this study and were used in developing the findings and recommendations. (Author)
