Complex systems engineering problems require robust modeling early in the design process in order to analyze crucial design requirements and interactions. This thesis emphasizes the need for such modeling through multiple model-based systems engineering techniques as they apply to the execution of search and rescue. Through the development of a design reference mission, this thesis illustrates how a search and rescue architecture can undergo multiple levels of model-based analysis in order to ascertain critical system behaviors. This way, design aspects can be assessed and modified before incurring the costs associated with incorrect implementation. Furthermore, the study seeks to identify which particular modeling techniques are most conducive to the search and rescue domain. Then, other modelers can build upon the work presented here in order to assess any architecture aspect from different operating procedures to emerging technologies. Ultimately, this study demonstrates that complex systems require multiple iterations across different models. Since each technique has strengths and limitations, it is not feasible to encapsulate every interaction without constructing multiple models. Systems engineering is constantly iterating and seeking to improve designs. Model-based systems engineering can help designers improve not only a search and rescue architecture but also any system today and in the future.
