A number of descriptions of systems of performance measurement have been published, and more work has been carried out recently to develop their use for estimating purposes. One of the key problems is that most of the systems described rely on a systematic database which is built up from analysis of a stable production system. Currently such stability is the exception rather than the rule for most shipbuilding companies. The paper reviews the problem, focusing on global measures which can allow overall performance to be assessed, and also on work station performance. It considers the relationship between the global and local measures and proposes a method which would allow performance to be established readily. A method of planning for an improved performance in the future, but during the life of existing contracts is also proposed.

In this paper a human performance engineering approach to increased work productivity is outlined. Three applications are summarized by way of illustrating its major advantages and features, one in manufacturing, one in a service, and one in a sales setting. The ingredients of this approach start with a precise statement of desired company objectives in terms of behavior changes that may be required of individual workers. An accurate and reliable behavior counting system is needed next to learn exactly what workers are doing so that graduated steps toward the final behavioral adjustment can be planned. A feedback system in the form of individual, public charting is then to be introduced. Following a suitable period, a potent and relevant positive consequence consistently should be given for behavior increases or for maintenance of an acceptable performance. Various safeguards, tests for effectiveness, and implications are discussed.

Draft STEP application protocols, developed by the Navy Industry Digital Data Exchange Standards Committee (NIDDESC), have been issued to define the information content of a product model for a ship. The work reported in this paper combines the existing CAD models of the DDG51 Class design with a newly developed non-graphic database so that the overall information content complies with the STEP protocols. This work represents the first-time implementation of the application protocols and is a significant step in the Navy's plan to do the design of variants of the DDG51 Class totally in CAD. The combined graphic/non-graphic database is referred to as the DDG51 engineering product model. Emphasis has been placed on populating the non-graphic database with the information necessary to perform all required engineering analyses. The basic schema described in this paper may be extended to support other areas of interest, such as logistics support. technology. As a cost saving initiative and quality improvement measure, the Navy has implemented the use of 3-D Computer Aided Design (CAD). This effort required the development of leading edge CAD technology and the achievement of a cooperative (rather than competitive) success story by the two DDG51 Class shipbuilders and other industry participants. Over 2,500 drawings, many of which contain over 30 sheets per drawing, are required to build an AEGIS destroyer. Maintaining an error free design baseline defined by these drawings has proven to be a challenge in a 2-D manual environment. To improve efficiency, the entire design is being converted to 3-D CAD. The DDG51 design consists of 77 design zones. A 3-D computer generated representation of each of these zones is being developed. These models contain library parts defining equipment and machinery arrangements, structure, ventilation, electrical, and piping distributive systems.

The Twenty-Second Symposium on Naval Hydrodynamics was held in Washington, D.C., from August 9-14, 1998. It coincided with the 100th anniversary of the David Taylor Model Basin. This international symposium was organized jointly by the Office of Naval Research (Mechanics and Energy Conversion S&T Division), the National Research Council (Naval Studies Board), and the Naval Surface Warfare Center, Carderock Division (David Taylor Model Basin). This biennial symposium promotes the technical exchange of naval research developments of common interest to all the countries of the world. The forum encourages both formal and informal discussion of the presented papers, and the occasion provides an opportunity for direct communication between international peers.

Methods of improving the level of pre-contract design definition and the quality of information relating to steelwork are described. This information is combined with a comprehensive database of manufacturing process information to provide a system for estimating the work content of the main structural steelwork of ships such as ro-ro vessels. Procedures are described which facilitate consistent estimates to be made while minimizing data handling requirements and increasing the flexibility of the method at the concept design stage.
