Resource allocation and scheduling optimization program developed by the US Forest Service.

Planning And Decision Process Phases/Steps Served

Developed and maintained by the US Forest Service, the primary role of Spectrum is to model alternative resource management scenarios applied to landscapes through time in support of strategic and tactical planning. Spectrum models optimize resource allocation and scheduling in the context of achieving defined management objectives for any area over a specified time horizon. This includes scheduling vegetation manipulation activities to achieve ecosystem management objectives; modeling resource effects and interactions within management scenarios; and exploring tradeoffs between alternative management scenarios in support of informed decision making. Model highlights include: flexible spatial and temporal problem dimensions; multiple mathematical programming options; flexible objective function specification; ecological simulation and natural disturbance modeling; and nonlinear approximation.
