RYAN, JCJONS, OPJ. Christopher Ryan:earned his bachelor's and master's degrees in Naval Architecture from Webb Institute and MIT
respectively. He spent three years at the Advanced Marine Technology Division of Litton Industries working on the DD-963 class ship design and related computer aided design projects. he subsequently went to the Navy Department concentrating on early stage design of surface combatants for 12 years including work on the FFG-7 Sea Control Ship CSGN and CVV aircraft carrier projects. He then shifted focus and became the technical director for the Computer Supported Design Program in NavSea for five years. Mr. Ryan has served in several supervisory positions within the Ship Design Group in NavSea since that time. He is currently the project manager for the Ship Design Acquisition and Construction Process Improvement Project. Otto P. Jons:received a Diplom Ing. in shipbuilding from the Technical University of Hannover
W. Germany and an M.S. in naval architecture and marine engineering from the Massachusetts Institute of Technology in 1967. He then joined Litton Ship Systems where he was responsible for the preliminary design of the DD-963 hull structure and then for ship systems as manager LHA Ship Systems Engineering Department. From 1972 to 1974 he was principal research scientist at Hydronautics. In 1976 as technical director he helped establish the local office of Designers and Planners. Otto Jons was one of the co-founders of Advanced Marine Enterprises Inc. in 1976 where he is corporate vice president engineering.

In the spring of 1990, the NavSea Chief Engineer initiated a project to improve the design, acquisition and construction (DAC) of U.S. Navy ships. The project's objectives are to reduce the time and cost of acquiring and operating Navy ships while improving their quality, unlike previous studies on the subject, the project utilizes a rigorous process analysis approach and attempts to use quantitative measures as the basis for recommending improvements. The paper is, of necessity, a status report on the progress of this project. Topics covered include: the DAC process;a look at the current state of ship acquisition time, cost, and quality;the methodology for process improvements;and early findings.

The basis of a comprehensive real-time knowledge based system for control structure design and supervisory control is developed using the MUSE AT toolkit. Representation of control engineering knowledge as procedural code in an object-based structure ensures that the knowledge base is easily understood and modified by domain experts. The simple learning capability that has been implemented has proved to be extremely useful and is being developed further as part of continuing research in this area. It is also hoped to extend the capabilities of the supervisory modules particularly in dealing with loop interactions, the prediction and diagnosis of faults and the provision of an intelligent operator interface.< >

We consider the problem of a tandem cold rolling mill to achieve correct output gauge, and satisfactory shape, and surface finish. The essential process variables are roll force, shape and thermal roll crown. The formulation of the equations for these key variables is described. The scheduling problem is formulated as a constrained two point boundary value problem. This is solved using conjugate gradient and projection techniques developed for optimal control problems. Results showing the improvements which can be made in strip shape and general mill operating conditions, by optimising the schedules, are included and discussed.
