Class AlarmTripScheduleGenerator

java.lang.Object

neqsim.process.mechanicaldesign.AlarmTripScheduleGenerator

All Implemented Interfaces:

Serializable

public class AlarmTripScheduleGenerator
extends Object
implements Serializable

Auto-generates alarm and trip setpoints from process design envelopes.

Walks all unit operations in a ProcessSystem and generates alarm/trip setpoints based on operating conditions and design margins per IEC 61511 and NORSOK I-001/I-002 practice. For each measurable variable (pressure, temperature, level, flow), the generator produces LO, HI, and HIHI/LOLO setpoints from operating values and equipment design limits.

Usage:

AlarmTripScheduleGenerator gen = new AlarmTripScheduleGenerator(process);
gen.generate();
String json = gen.toJson();
