The key to designing a real-time, large, complex system is to optimize the design to meet the requirements and desired measure of effectiveness. In order to achieve this, the system engineeranalyst must have the capability to specify the design goalscriteria, to quantify various aspects of the design, and to perform trade-offs among different design goals. One of the mechanisms that provides these capabilities is the System Design Factors. Whether the system design emphasis is on real-time, largeness, complexity, parallelism or any specific criteria, it requires a set of System Design Factors to describe the properties, attributes and characteristics of the system. Each System Design Factor must have its own metric to gauge every detail of that system. The metric describes the weaknesses and strengths of a specific area in the design. In turn, the correlation of the System Design Factor characterizes the completeness and robustness of the system. Whether the system is designed top-down, bottom-up, or middle-out, the System Design Factors have major influence in design capture and analysis, design structuring decisions, allocation decisions, and trade-off decisions between various design structures and resource allocation candidates. Systems design factors, Structure design, Resource allocation, Optimization, Trade-off analysis, Large complex real-time system.
