Class ProductionImpactAnalyzer

java.lang.Object
neqsim.process.util.optimizer.ProductionImpactAnalyzer
All Implemented Interfaces:
Serializable
public class ProductionImpactAnalyzer extends Object implements Serializable
Analyzer for assessing production impact of equipment failures.

This class provides comprehensive analysis of how equipment failures affect production rates and helps determine optimal operating strategies during degraded conditions.

Key Capabilities

  • Analyze impact of single equipment failure
  • Compare degraded operation vs. full plant shutdown
  • Find optimized operating point with failed equipment
  • Rank equipment by criticality
  • Identify bottleneck shifts

Example Usage


// Create analyzer
ProductionImpactAnalyzer analyzer = new ProductionImpactAnalyzer(processSystem);
analyzer.setFeedStreamName("Well Feed");
analyzer.setProductStreamName("Export Gas");

// Analyze compressor failure
ProductionImpactResult result = analyzer.analyzeFailureImpact("HP Compressor");
System.out.println("Production loss: " + result.getPercentLoss() + "%");
System.out.println("Recommendation: " + result.getRecommendedAction());

// Get criticality ranking
List<ProductionImpactResult> ranking = analyzer.rankEquipmentByCriticality();
