The primary purpose of this discussion is to introduce a new version of the REAPS Program. In 1971 a Maritime Administration (MarAd) Advisory Group recognized a void in the area of computer aided shipbuilding. In response, MarAd acquired rights to the AUTOKON-71 system, the most widely used system in Europe. MarAd and the participating shipyards recognized the need to provide maintenance and support for the AUTOKON system. That effort was sponsored and paid for jointly by the industrial users and the government. It soon became apparent to all concerned that there was much more to be gained from computer applications in the shipyard than just running the AUTOKON system. A total shipyard program for computer automation beyond AUTOKON was needed. It was this decision that gave birth to the Research and Engineering for Automation and Productivity in Shipbuilding (REAPS) program; a joint participation program involving five shipyards, MarAd, and IITRI. Its purpose was to identify and address common problems in ship construction. The advantages were obvious. Participants could pool both the technological know how in identifying and solving problems and their resources to solve a common problem only once not repetitively at every shipyard. The REAPS program, a new concept in cooperative developments among several shipyards, was working. One thing began to change--the objectives of our development projects. Originally, they were oriented to a specific computer system, AUTOKON; now they were becoming non-system oriented, standalone modules with no relationship to a specific computer system or software package. A new concept was needed. The "new" REAPS program as it has evolved to date is a non-systems oriented program with the separation of all AUTOKON related activities. The overall concept of the new REAPS Program consists of five basic elements: Advance Planning, Technology Assessment, Development Program, Technology Information Services and Discretionary Development.

What is the optimum organizational pattern in a shipyard for application of Numerical Control (NC)? A precise answer to this question does not exist. Many things influence a shipyard s operation: management attitudes, personnel availability, finances, and geographical limitations are but a few. Without consideration for any of these factors, a good NC structure for a shipyard should be as follows: A computer applications section to develop or procure the software necessary for a good NC program; A fairing group, established in a department, that has the ability to manually fair a ship, and the adaptability to learn computer fairing; A scientific section that uses the data base for hull calculation programs, and provides the basic information needed for fairing and hulload; A hull engineering department, producing accurate drawings by utilizing the data base for drafting purposes, and supplying detailed information for fairing and hulload; A hulload group initial loading comprised of engineering and NC loft people -- of the data base should be done by hull engineering, with the NC loft, taking responsibility for the maintenance of hulload when part generation begins; and An NC mold, under production management, whose duties include part generation and nesting programming, as well as data base control -- this group should have access to whatever equipment is necessary to accomplish their duties. A review of the NC operations of several successful shipyards will be an effective method of determining a suitable NC system. Such a study will enable management to decide what hardware, software, and organizational pattern would best suit their needs.

The Ship Production Committee is made up of representatives from approximately twenty-four shipbuilders plus the American Bureau of Shipping, U.S. Coast Guard, U.S. Navy Research and Development and, of course, the Maritime Administration whose budget is the backbone of this vital project. We poll the industries to see who would use the results of a research project. The more yards that would use, the higher the priority; the higher the potential saving, the higher the priority. We then list the projects in priority sequence, see how far the budget reaches for the year, and submit those to the Maritime Administration for approval. When approved and a shipyard agrees to act as sponsor, a suggested contract is worked out between the sponsor shipyard and the Maritime Administration. The most valuable result of this program is that the shipyards are talking to each other at the working level for the betterment of our industry.

The objective of this paper is to demonstrate to its readers that it is possible for a shipyard, the size of Zigler, to maintain a small but an effective engineering group provided it is supported by a powerful tool like PRELIKON. Further, an inhouse engineering department in a shipyard reduces communication gaps between engineering and production, thus giving rise to increased productivity.

NAVSEA's ongoing efforts to improve, standardize and integrate shipyard process instructions are outlined. This plan, will combine the best features of various DOD, Navy and Private programs including for example: (1) the navy technical information presentation programs, (2) DOD computer aided time standards, (3) Navshipyd/Ordnance Station EM & S automated support (NEAS), (4) the Carnegie Mellon/USS CARL VINSON CUN 70 ZOG program, (5) shipboard nontactical ADP system (SNAP), (6) NAVSHIPYD Norfolk - work planning and control systems - PROMPT, and (7) technical repair standards (TRS) program. Specific aspects of these programs will be discussed including computer aided authoring, group technology, and common vocabularies, and a status report of these efforts as well as future plans will be provided.

The Research and Engineering for Automation and Productivity in Shipbuilding (REAPS) program aims at increasing U.S. shipyard productivity. The organization, activities and current and planned development projects of the program are reviewed. The 1980 symposium focuses on developing a consensus on a format for long range facility plans, with an emphasis on cost effectiveness and environmental impacts.
