ShipDoc User Guide, Richardson & Brown, October 1984 (0107)
This user's guide is for the Ship Design Optimization Code (SHIPDOC), a renamed extension of Mare Island Naval Shipyard computer program ARCJ6. SHIPDOC solves for a vehicle which is optimized subject to user defined optimization criteria and constraints. Any type of vehicle may be input to SHIPDOC, since the vehicle description is data to SHIPDOC. The vehicle description (data base) is provided by the user, and can vary in scope and detail as required by the user, since there are no built-in or hard-wired vehicle descriptions, constraints, or objective functions - all are provided by the user. The guide covers all versions of SHIPDOC since its inception in 1969, and includes the latest version, V409300, which runs in 1/3 to 1/15 of the time of previous versions while providing more user versatility. The guide briefly covers the rationale for treating the conceptual and preliminary design problem as that of minimization subject to constraints. The bulk of the guide shows the directives used to build the ship description (data base) files, the directives used to modify the data base and run the program, and discusses the output expected.
