Infrastructure Study in Shipbuilding: A Systems Analysis of U.S. Commercial Shipbuilding Practices.

摘要

This report documents the results of the first phase of the Infrastructure Study in Shipbuilding (ISIS). The purpose for the first phase was to accurately document the current processes used to build commercial ships in the United States. These results have provided an increased understanding of the commercial shipbuilding process and have also provided a strategic planning tool capable of determining the length of time required to market, design, build and deliver a typical merchant ship in the united states. The methodology used to document the shipbuilding process was IDEF. The resulting product was an IDEF function model composed of 272 interrelated activities. A subset of seventy of these functions were analyzed with critical path methodology to produce a Gantt chart representing an atypical merchant ship acquisition program. Data was taken from a recently completed merchant ship program and used to establish an overall process duration for these seventy functions.
