摘要

The aim of system design is to define an optimal integration of components for the achievement of an overarching objective. As a result, engineering systems often cannot be designed with the disciplines meeting in isolation, but instead require collaboration for a synergism of goals, especially in aviation-based systems where tradeoffs are inherent to the design. Furthermore, defense-related projects require a strict acquisition process that requires companies to submit proposals for contracts. The system design method proposed here is geared towards the proposal stage of design and is aimed at enabling objective, informed design decisions. As such, the method uses the system's properties in a utility function-based evaluation to determine the best alternative. Towards these ends, the method defines criteria critical to the system's evaluation and functions to translate the system's properties related to these criteria into scores. The system's properties are derived from relationships with the components properties and between the components and their environment. As a result, the method translates component properties into system properties, which are then turned into scores.
