Message: These are harvest scheduling models of hypothetical forest planning problems
where we maximize net timber revenues over a planning horizon subject to
four set of constraints: 
1. Each management unit can be harvested only once over the planning
horizon, 
2. Volume harvested in one planning period should not be less or more than
some portion of that in the preceding period,
3. Area-weighted average age of the forest by the end of the plan should not
be less than a certain target age.
4. Clearcut size in any planning period has to be below a specific limit.

Decision variable are management units and generalized management units
(group of management units with a combined area not exceeding the limit on
clearcut size) and can be either fully harvested or left untouched in any
planning period, therefore there is a binary restriction on the decision
variables.

I hope you find these examples useful. Please let me know if you have any
questions.
