BERG, DAVID J.JONES, WALTER S.MARRON, HUGH W.David Berg
a native of Michigan received his Bachelor's Degree in Mechanical Engineering from the Michigan Technological University in 1951 after which he began his career with the Bureau of Ships in the Machinery Design Branch on noise shock and vibration problems. He was project engineer for the axial flow pumpjet development on USS Witek (DD848) and USS Glover (AGDE1) and received his Master of Engineering Degree in Naval Architecture in 1964 from the University of California Berkeley. Mr. Berg is currently acting head of the Ship Performance and Trials Section of the Propulsion Systems Analysis Branch in the Naval Ship Engineering Center. He received the Meritorious Civilian Service Award in 1962 for contributions to the design of the USS Thresher (SSN593) and was awarded the Superior Performance Award for Outstanding Performance in 1966. Hugh Marron
a native of Pennsylvania received his Bachelor of Science Degree in Civil Engineering from the Pennsylvania State University in 1939. Upon graduation he was employed for one year with the Pennsylvania Department of Highways as a construction engineer. In July 1940 he became a Marine Engineer at the Philadelphia Naval Shipyard where after a period of apprenticeship and special training in this new field he was assigned to the Machinery Scientific Group of the Design Division. Then in October 1945 he was transferred to the Design Division of the Bureau of Ships. Mr. Marron is now a Project Coordinator in the Propulsion Power and Auxiliary Systems Division of the Naval Ship Engineering Center. Walter S. Jones
a native of Virginia graduated from the George Washington University with a BME in June 1958. From July of that year through June 1965 he served with the Machinery Design Branch of the Bureau of Ships where he was Project Engineer for the Hydroneu-matic Ram Jet and Water jet Propulsion Systems. Mr. Jones is currently the Machinery Coordinator for the Computer Aided Ship Design Program in the Naval Ship Engineering Center.

During the early stages of pre-Contract Definition ship design, the use of computer models now allows the design to be manipulated on a total system basis. That is, a change to any component of the design is immediately and totally reflected in the physical characteristics of the overall ship design. The models that make this possible and the efforts to extend this capability into Concept Development are described. The implications of this for the subsystem designer, in particular the electronics designer, are explored.

RAWAT, Pwho began his education in his native India
received a Bachelor of Technology degree with honors from the Indian Institute of Technology in 1957. His subsequent education includes S. M.‘s in Industrial Management and Naval Architecture & Marine Engineering from M. I. T. in 1961 and a professional degree in Naval Architecture from the same institution in 1965. Rawat's career began as a Naval Architect in preliminary design with the Hamburg firm of Howladtswerke in 1958. A year later he performed as a research assistant in M. I. T.'s School of Industrial Management for a Ford Foundation Project for a top management training program for India. After this two-year period he acted as the head of the Department Head of Engineering at the Ghana Nautical College in West Africa until 1963. He returned to M. I. T. afterwards to work as a research assistant in Naval Architecture on structural optimization programs. From 1965 to 1966 he filled the capacity of Naval Architecture with M. Rosenblatt & Son in the area of structural design on such projects as MOHOLE AGOR 14 and Catamaran Hull. Since 1966 Rawat has been working in various capacities with Litton Industries: Senior Naval Architect on the FDL Project Section Manager of Hull Structures for the LHA and DD Projects
and his present position as Section Manager for Computer Aided Ship Design.

Many useful conclusions can be drawn if hull structural design is considered as a system. Proper definition of system objectives enables setting up of meaningful long range and intermediate goals. Current state-of-art in systems engineering is such that the system objectives can be denned in mathematical form. This provides meaningful scales for progress measurement. The engineering function is to meet the goals set by systems engineering. The state-of-art in engineering has a considerable impact on the definition of system objectives. In recent times we have made considerable progress in developing analytical techniques. Many interesting conclusions result from our experience in using the analytical tools in an iterative manner for design. By using relatively simple algorithms for iteration the analytical processes can be sequenced in such a manner that optimum solution is guaranteed even under a large and complex set of design constraints. Use of computers makes it possible to generate the scantlings using iterative approach with such speed that many important structural configuration decisions can be made by means of thorough parametric analyses. The system objectives therefore are very different in scope today and they should be further modified as technology advances. There are several problems that can be recognized and solved in the systems context. Smooth man-machine operation is an example of this.
