Research Areas

My research activities involve identifying and/or developing formal, repeatable approaches for design in the Systems of Systems (SoS) context. A significant challenge of design within an SoS is determining the appropriate mix of independent systems to meet a set of needs or provide a set of services. Comprehensive methods do not yet exist for allocation of resources that have variable properties. Because the constituent systems are capable of independent operation, they may collaborate or compete; design methods must incorporate aspects of game theory. Evolution of an SoS over time will be more efficient if design methods include making decisions about when to retire existing assets, when to add new assets, and when to upgrade assets with improved technologies; extensions of dynamic programming are needed for this. Systems of Systems are (and will be) designed and operate under uncertainties. This requires new, or greatly expanded, approaches for design under uncertainty and reliability-based design. Some additional details about these efforts are available at Prof. Crossley's personal web page: http://cobweb.ecn.purdue.edu/~crossley/
