Class SplitterCapacityStrategy

java.lang.Object
neqsim.process.equipment.capacity.SplitterCapacityStrategy
All Implemented Interfaces:
EquipmentCapacityStrategy
public class SplitterCapacityStrategy extends Object implements EquipmentCapacityStrategy
Capacity strategy for splitter equipment.

  • Method Details

    • supports

      public boolean supports(ProcessEquipmentInterface equipment)
      Checks if this strategy supports the given equipment.
      Specified by:
      supports in interface EquipmentCapacityStrategy
      Parameters:
      equipment - the equipment to check
      Returns:
      true if this strategy can evaluate the equipment

    • getPriority

      public int getPriority()
      Gets the priority of this strategy.

      When multiple strategies support the same equipment, the one with higher priority is used. Default priority is 0. Use positive values for more specific strategies.

      Specified by:
      getPriority in interface EquipmentCapacityStrategy
      Returns:
      the priority value (higher = more preferred)

    • getName

      public String getName()
      Gets a descriptive name for this strategy.
      Specified by:
      getName in interface EquipmentCapacityStrategy
      Returns:
      strategy name

    • getEquipmentClass

      public Class<? extends ProcessEquipmentInterface> getEquipmentClass()
      Gets the equipment class this strategy handles.
      Specified by:
      getEquipmentClass in interface EquipmentCapacityStrategy
      Returns:
      the equipment class

    • evaluateCapacity

      public double evaluateCapacity(ProcessEquipmentInterface equipment)
      Evaluates the current capacity utilization of the equipment.

      Returns a value between 0 and 1+ where:

      • 0.0 = no load
      • 1.0 = at design capacity
      • >1.0 = over capacity
      Specified by:
      evaluateCapacity in interface EquipmentCapacityStrategy
      Parameters:
      equipment - the equipment to evaluate
      Returns:
      capacity utilization as a fraction

    • evaluateBasicCapacity

      private double evaluateBasicCapacity(Splitter splitter)
      Evaluates basic capacity when splitter doesn't have constraint interface.
      Parameters:
      splitter - the splitter to evaluate
      Returns:
      utilization factor (0-1+)
