Complexity a Complexity is the degree to which the set of possible states of a system exceeds the set of desired states a Complexity can be measured V Information required to describe all the components, their interconnections and their interactions V Number of homogeneous/dissimilar elements homogeneous/dissimilar interconnections and ways components are organized
Complexity Complexity is the degree to which the set of possible states of a system exceeds the set of desired states Complexity can be measured È Information required to describe all the components, their interconnections and their interactions È Number of homogeneous/dissimilar elements, homogeneous/dissimilar interconnections, and ways components are organized
Complexity a Complexity is subjective V Influenced by user perception and presentation scheme N Ex: cruise control system in automobiles Low apparent complexity as presented to drivers: knobs buttons High apparent complexity if you include physical parts such as electromechanical components or logics such as control laws
Complexity Complexity is subjective È Influenced by user perception and presentation scheme È Ex: cruise control system in automobiles • Low apparent complexity as presented to drivers: knobs, buttons • High apparent complexity if you include physical parts such as electromechanical components or logics such as control laws
Complexity a Complexity can be decomposed V Essential complexity: minimum level of complexity that is essential to deliver system function V Gratuitous complexity: additional complexity beyond essential complexity
