CONCLUSION
framework, presented in a matrix format, offers
An initial framework has been established for
a straightforward method for describing and
evaluating operations and functions commonly
evaluating candidate automation measures in
occurring at navigation locks and dams that
terms that are useful for operational planning
may offer opportunities for automation. This
and management decision-making.
