  System of systems engineering seeks to analyze, design and deploy collections
of systems that together can flexibly address an array of complex tasks. In the
Complex Adaptive System Composition and Design Environment program, we
developed "network operads" as a tool for designing and tasking systems of
systems, and applied them to domains including maritime search and rescue. The
network operad formalism offers new ways to handle changing levels of
abstraction in system-of-system design and tasking.
