Conceptual Design to cost: A New Systems Engineering Tool.

Abstract. Incorporating cost considerations in the system design is a critical part of the system development process. However, since current methods of incorporating cost considerations into the design need knowledge of the cost of the actual components to be used in the system; the technique known as Design to Cost (DTC) is not suitable for use in the conceptual or in the preliminary design phase where it is most needed.

This presentation introduces a methodology for performing DTC in the front - end design phase that has been used with some success to provide cost estimates. This methodology, Conceptual DTC (CDTC) fills a critical gap in the systems engineer’s toolbox.

This presentations begins with a short review of DTC, and then describes the CDTC methodology which allows cost factors to be treated in the same manner as the other system factors such as functional, performance, reliability and safety etc. as an integrated part of the design process, rather than as an external bolt-on.

Architecting a System of Systems Responding to Maritime Domain terrorism by Orthogonal Array Experiment

Abstract: In this talk we will discuss a solution to the problem of architecting a conceptual, cost-effective, near-term system of systems (SoS) to respond to terrorist threats to emanating from the maritime domain.  We will also discuss a systems approach to defining SoS architectures.  We formulate the SoS architecting problem as an assignment problem, which is then solved using the orthogonal array experiment (also known as the Taguchi method for quality control). The optimality of the resulting SoS architecture is validated against a heuristically developed architecture and an optimal effective, but not necessarily cost-effective, architecture obtained also with the orthogonal array experiment approach. The results of the orthogonal array experiment method underline this successful exploratory work in architecting systems of systems.
