Class ProductionOptimizer.OptimizationObjective

java.lang.Object

neqsim.process.util.optimizer.ProductionOptimizer.OptimizationObjective

Enclosing class:

ProductionOptimizer

public static final class ProductionOptimizer.OptimizationObjective
extends Object

Container for optimization objective configuration.

An objective defines a quantity to optimize (maximize or minimize) during the optimization process. Multiple objectives can be combined with weights to form a composite score.

Java Example

OptimizationObjective throughput = new OptimizationObjective("throughput",
    proc -> proc.getUnit("outlet").getFlowRate("kg/hr"), 1.0, ObjectiveType.MAXIMIZE);

Python Example (via JPype)

from jpype import JImplements, JOverride

@JImplements("java.util.function.ToDoubleFunction")
class ThroughputEvaluator:
    @JOverride
    def applyAsDouble(self, proc):
        return proc.getUnit("outlet").getFlowRate("kg/hr")

throughput = OptimizationObjective("throughput", ThroughputEvaluator(), 1.0)
