Adaptive Smart Queue System (Behavior-Aware Cloud Service)

Overview

Adaptive Smart Queue System is a cloud-native application that monitors real-time queue data, predicts waiting times, and dynamically optimizes service allocation.

The system demonstrates how cloud computing enables:

• Real-time data processing
• Scalable architecture
• Intelligent decision-making

Methodology

1. Data Simulation
   Queue events are generated via scripts or user input.

2. Data Processing
   Backend ingests and stores queue data in DynamoDB.

3. Prediction
   ML model estimates waiting time based on:

   • queue length
   • service rate
   • arrival patterns

4. Decision Engine
   System evaluates load and suggests:

   • opening new counters
   • redistributing queues

5. Visualization
   Frontend displays real-time queue insights.

---

Setup (High-Level)

1. Clone repository
2. Configure environment variables
3. Run backend (Docker)
4. Run frontend
5. Deploy to cloud (EC2)

Future Improvements

• Real-time streaming (Kafka/Kinesis)
• Advanced ML (time-series forecasting)
• Auto-scaling integration
• Multi-location queue optimization
