Fundamental Models for Missions of Engineered Systems
Haifeng Zhu · 2019 IEEE International Systems Conference (SysCon) · 2019
Designing a system requires clear evaluations of the system's abilities in supporting missions/requirements, which can be subsequently used for evaluating a system's -ilities such as adaptability. In reality, the missions and requirements can be arbitrary, ambiguous, and contain overlapping contents, causing difficulties in clear understanding and quantifications. This paper studies these problems, provides fundamental insights to models on missions/requirements, using Dynamical Systems or Transition Systems. It generalizes the Missions/Requirements Evaluation Space, presents the fundamental and practical semantics to effectiveness functions of a mission and a set of missions. Based on our prior work of hierarchical task breakdown, using weights and probabilities, a top-down mission analysis process is mathematically shown. These allow them to be Measures of Effectiveness (MOE) in practice, and also generalize the adaptability theory. An HVAC example is used to demonstrate the generalized models that are backward compatible with existing adaptability theory. Copyright © 2019 United Technologies Corporation.
