... is a design engineering environment in which computer-aided design technology is used to continually assess and improve the quality of a product during the active design phases as well as throughout its entire life cycle by integrating and optimizing design attributes for producibility and supportability as well as for performance, operability, cost, and schedule. The interest in the application of ULCE to the structural components of advanced weapons systems is prompted by the observation that in these systems the life-cycle cost is dominated by product support, with data for manned aircraft showing that 70 percent of lifecycle cost is associated with support after deployment.

... Accelerate the development of CAD-CAM systems that incorporate complete product descriptions material performance data, and manufacturing process information as well as features-based modeling for use with product and process modelers that support producibility, reliability, serviceability, etc. Expand the application of analytical methods.

... The committee concluded that because the development of ULCE requires a strong interdisciplinary research and development program involving a number of technologies; e.g., computer, materials, analytical modeling and simulation, decision theory as well as an equally strong educational commitment to support the program, the following general recommendations should be addressed prior to consideration of those identified under the critical issues: The overall scale of the ULCE effort should be defined; a detailed R&D plan and budget for a 10- to 15-year technology development program must be prepared. A demonstration project for ULCE should be established using a major subsystem or module of a current vehicle and then redesigning, reengineering or remanufacturing the subsystem or module.

... The committee believes that, even though the challenges are major, the benefits justify initiating a significant research program as soon as possible.
