In current practice, design documentation often fails
to support the activities of design understanding,
communication, and redesign. A Design History Tool has been
developed to improve current design documentation. This
tool is a computerized design history that represents and
plays back important information generated during the
process of designing a...
The concept of large-scale natural resources planning and
management is not new. The idea that resources and their human users occur as systems over large geographic areas has a long established tradition in forest, range, water, and air management sciences. Recent trends in this thinking concern the recognition of the...
