Validation Rule:	≥0
Key Property:	No
Description:	Maximum ramp down rate
Detail:

Facility Max Ramp Down sets a limit on the rate at which the facility can decrease Production from one interval to the next. The value is the maximum change in production per hour. This limit applies for Production ranges between the minimum operating level and Max Operating Level.

For multi-unit facilities the available ramp down is defined as:

Max Ramp Down (total) = Units Operating × Max Ramp Down

By default the ramping limit is a hard constraint meaning that no violation is allowed. To create soft constraints with a penalty price use the Max Ramp Down Penalty property.
