National Academies Press, 2002. 198 p.

The goal of virtual analysis over the life cycle of a product or system — from lust to dust —is as lofty as it is difficult to attain. Before any capital expenditure is made, we seek to use modeling and simulation to aid in, among other things, concept formation and evaluation, architecture development, specification, detailed design (of both the product or system and the manufacturing process to create it), risk analysis, provision for support in the field, life-cycle costing, and disposal. Strong progress toward this difficult goal will provide increased effectiveness of the product or system in the field, reduced cost and risk, and reduced time to deployment—that is, the right product, better, cheaper, faster.
The National Research Council's Committee on Modeling and Simulation Enhancements for 21st Century Manufacturing and Acquisition was formed in response to a request from the Defense Modeling and Simulation Office (DMSO) of the Department of Defense. The committee was asked to do the following: (1) investigate next-generation evolutionary and revolutionary M&S capabilities that will support enhanced defense systems acquisition; (2) identify specific emerging design, testing, and manufacturing process technologies that can be enabled by advanced M&S capabilities; (3) relate these emerging technologies to long-term DOD requirements; (4) assess ongoing efforts to develop advanced M&S capabilities and identify gaps that must be filled to make the emerging technologies a reality; (5) identify lessons learned from industry; and (6) recommend specific government actions to expedite development and to enable maximum DOD and U.S. commercial benefit from these capabilities.
Private industry, universities, federally funded research and development centers, government laboratories, and university-affiliated research centers were all represented on the committee. (Biographical sketches of committee members appear in Appendix A). The committee met five times between June 2000 and June 2001 to review previous literature on acquisition-related M&S (see Appendix B), to hear briefings from national experts on relevant topics (see Appendix C), and to discuss and develop their conclusions and recommendations. On the basis of its statement of task, the committee focused on M&S in acquisition and its associated functional areas, especially manufacturing.
Such areas as M&S in training and logistics analysis, as well as detailed discussion of systems engineering, were considered as beyond the scope of the study.
The committee has identified steps for progress toward widespread, systemic use of modeling and simulation in manufacturing and acquisition of systems on four fronts: (1) enhancement of modeling and simulation technology, (2) enhancement of information technology infrastructure, (3) building experience in the use of modeling and simulation in large-scale enterprises, and (4) addressing cultural changes needed if modeling and simulation are to become truly important enablers for manufacturing and acquisition. Recommended steps involve the federal government, academia, and industry. They must be undertaken simultaneously in all communities for meaningful progress to be realized.
