FIGURE 3-1 Overlay of tools that bridge design and manufacturing. Each ellipse within the chart represents a different tool category. Ellipse size connotes the comprehensiveness of the capabilities of those tools within the matrix, and color shading (or lack thereof) highlights the focus of the various tools’ strengths in design, manufacturing, business operations, or management. Blue shades indicate a concentration in design, while green trends into manufacturing. Yellow hues show a proclivity toward business operations. Orange indicates the prominence and importance of data management. Ellipses void of color detail project management functions.

design optimization software tools that bundle discrete tools in order to facilitate multiprocess optimization are being introduced. Examples of such software are Synaps/Epogy, Isight, and Heeds from Red Cedar Technology. While these software packages look attractive in principle, human input still becomes essential to bridge the gaps between various analytical tools.

This chapter covers in depth the state of affairs within each of five different tool categories:

  • The section titled "Systems Engineering Tools" explains how philosophies are expanding from narrow discrete-element minimization to design-trade-space optimization strategies and, while many tools exist within their own specialized field, recommends the need for supervisory control and common links between individual routines.

  • "Engineering Design Tools" discusses the current capabilities of engineering design methods and software and their general lack of interoperability. It makes recommendations to improve communication between design and manufacturing software so that engineering models can be exchanged and simulated in multiple
