In this tutorial, a domain-agnostic framework, based on Design of Experiments, is presented which provides holistic performance evaluation of complex systems. This framework leverages systems engineering principles for identifying design variables in large design spaces which are then investigated by statistical methods (e.g., analysis of variance) for establishing statistical significance and quantifying their impact on end system performance. This tutorial will discuss theoretical foundations for performing design and analysis of experiments, followed by a hands-on application on an information fusion system example which can be easily transferred to domain-specific implementation of a complex system in the
participant’s area of interest (Information fusion systems are widely applicable in defense applications, self-driving cars, and autonomous systems). A refresher on Monte-Carlo simulations and hypothesis testing will also be provided. At the conclusion of the tutorial, participants will be able to formulate an experimental design for complex system performance evaluation, employ hypothesis testing for comparing uncertain data, perform analysis of variance (ANOVA) to establish statistical significance of design variables and interactions, and perform multiple comparison range tests to quantify the impact of design variables and obtain sensitivity analysis of interactions for system performance evaluation.
Dr. Ali K. Raz is a research scientist at Purdue University’s Center for Integrated Systems in Aerospace. His research interests are in Complex Systems, System-of-Systems Engineering, and Information Fusion System. He was the recipient of Alexander Kossiakoff fellowship awarded jointly by the John Hopkins University and the International Council on Systems Engineering (INCOSE) for developing performance evaluation methods for system-of-systems.
