Decision Support Requirements in a Unified Life Cycle Engineering (ULCE) Environment. Volume 1. An Evaluation of Potential Research Directions

摘要

The goal of Unified Life Cycle Engineering is to develop an advanced environment that allows considerations of producibility and supportability to be integrated into the design process in a timely fashion, i.e., early in the design process, along with the usual considerations of performance, cost, and schedule. A key factor in being able to develop an ULCE design environment is the management of the design decision-making process in such a way as to ensure that designs, optimized among all the competing factors, both up front and downstream, can be produced. This report is the result of a study addressing the design decision support problem under ULCE. Volume I contains the results of the ULCE DSS Working Group efforts to outline a research and development plan for the design decision support for ULCE. Volume II is a review of the optimization techniques currently used or proposed to aid in the decision processes involved with competing requirements. The third volume of the report applies some of these optimization methods and other decision support techniques to actual design problems.
