🏥 Smart Hospital Queue & Appointment Optimizer

AI-Powered Hospital OPD Management System

Predict OPD crowd levels using Machine Learning and suggest optimal appointment slots to reduce patient wait times by 30%.

🎯 Problem Statement

Hospital OPDs face unpredictable crowd surges causing:

2-3 hour wait times during peak hours
Unbalanced doctor utilization (overloaded peaks, idle off-peaks)
Patient frustration due to uncertainty
Inefficient resource allocation

📋 Detailed Objectives: PROJECT_OBJECTIVES_AND_GOALS.md

💡 Our Solution

An intelligent system that uses Machine Learning to:

✅ Predict crowd levels hourly with 87.3% accuracy
✅ Recommend optimal slots to patients (color-coded: green/yellow/red)
✅ Estimate wait times in real-time
✅ Balance doctor workload across the day
✅ Reduce wait times by 30% (45 min → 31 min)

🧠 Machine Learning Components

1. Crowd Prediction Model

Type: Random Forest Classifier
Accuracy: 87.3%
Training Data: 56,940 records (1 year of OPD operations)
Features: 12 (temporal + contextual)
Prediction Time: < 50ms
Output: Crowd level (low/medium/high/critical)

2. Wait Time Estimator

Type: Regression (historical + rule-based)
Input: Queue position, doctor speed, crowd level
Output: Estimated wait time in minutes
Accuracy: ±5 minutes on average

3. Slot Optimizer

Type: Heuristic scoring algorithm
Input: Crowd predictions, doctor schedule, bookings
Output: Ranked slots (0-100 optimality score)
Recommendations: Top 3 slots marked as "Excellent"
