OPTI - Smart Workforce Scheduling App

OPTI is an intelligent workforce scheduling application powered by genetic algorithms and AI. It optimizes shift planning for small to medium-sized businesses while ensuring fairness, cost efficiency, and employee satisfaction.

🚀 Key Features

Core Scheduling

• Genetic Algorithm Optimization: Uses evolutionary algorithms to find optimal schedules
• Multi-objective Optimization: Balances coverage, cost, fairness, and employee preferences
• Real-time Updates: Drag-and-drop interface with instant synchronization
• Constraint Satisfaction: Respects labor laws, overtime limits, and rest requirements

AI-Powered Assistant

• Natural Language Processing: "Generate next week's schedule with minimal overtime"
• Explainable AI: Understand why specific scheduling decisions were made
• Intelligent Conflict Resolution: Automatically suggests fixes for scheduling issues
• Voice Commands: Hands-free schedule adjustments

Employee Features

• Shift Swapping: Request and approve shift trades
• Availability Management: Set preferences and blackout dates
• GPS Clock-in/out: Location-based attendance verification
• In-app Chat: Team communication and notifications

📱 Getting Started

Prerequisites

• Flutter SDK (>=3.0.0)
• Dart SDK
• iOS/Android development environment

Installation

1. Clone the repository:

git clone https://github.com/yourusername/opti.git
cd opti

2. Install dependencies:

flutter pub get

3. Set up environment variables: Create a .env file in the root directory:

OPENAI_API_KEY=your_openai_api_key
SUPABASE_URL=your_supabase_url
SUPABASE_ANON_KEY=your_supabase_anon_key

4. Run the app:

flutter run

🧬 Genetic Algorithm Engine

OPTI's scheduling engine uses a genetic algorithm that:

1. Initializes a population of random schedules
2. Evaluates fitness based on multiple objectives:
   • Coverage (30%)
   • Fairness (25%)
   • Cost efficiency (20%)
   • Employee preference match (25%)
3. Evolves schedules through crossover and mutation
4. Converges on optimal solutions over 50 generations

📊 Performance Metrics

• Schedule generation: < 2 seconds for 100 employees
• Conflict detection: Real-time
• UI responsiveness: 60 FPS
• Memory usage: Optimized for mobile devices
