ALAS Implementation for JSSP

The ALAS framework is specifically implemented for Job Shop Scheduling Problems (JSSP) with the following components:

JSSP-Specific Agents

• Job Agents: Individual agents responsible for scheduling specific jobs
• Supervisor Agent: Coordinates and aggregates schedules from all job agents
• Validation Agent: Validates schedules for constraint violations and optimality
• Optimization Agent: Performs makespan optimization and resource utilization

JSSP Workflow Steps

1. Initial Schedule Generation: Each job agent generates an initial schedule
2. Schedule Aggregation: Supervisor agent combines all job schedules
3. Validation: Validation agent checks for constraint violations
4. Optimization: Optimization agent improves makespan and resource utilization
5. Repair Iterations: If violations exist, repair agents fix them iteratively
6. Final Validation: Ensures the final schedule is valid and optimal

ALAS JSSP Execution Flow

# Initialize ALAS workflow
maple = MAPLE(task_specification)

# Run with full ALAS capabilities
maple.run(
    with_rollback=True,      # Enable rollback on failures
    validate=True,          # Enable self-validation
    optimize=True,          # Enable optimization

🚀 How To Run

1️⃣ Quick Start

1. Clone the repository:

   git clone https://github.com/yourusername/M-APPLE-OS.git
   cd M-APPLE-OS

2. Set up environment:

   # Create virtual environment
   python3 -m venv venv
   source venv/bin/activate  # On Windows: venv\Scripts\activate
   
   # Install dependencies
   pip install -r requirements.txt

3. Configure API keys: Create a .env file in the root directory:

   OPENAI_API_KEY=your_openai_key_here
   ANTHROPIC_API_KEY=your_anthropic_key_here
   GOOGLE_API_KEY=your_google_key_here
   DEEPSEEK_API_KEY=your_deepseek_key_here

2️⃣ Run ALAS Workflows

Option A: Run Complete ALAS Evaluation

# Run ALAS with Gemini-2.5
python3 applications/run_all_maples_optimization_comparison_ablation_gemini-2.5.py

Option B: Run Framework Comparisons

# Compare Multi-Agent Systems
python3 applications/run_jssp_framework_comparison.py

# Compare Single-Agent Models
python3 applications/run_jssp_framework_comparison_singleagent.py

3️⃣ Generate Reports

# Success rate analysis
python3 generate_success_rate_report.py

# Error rate analysis
python3 generate_error_rate_report.py

# Optimal rate analysis
python3 generate_optimal_rate_report.py

# Execution time analysis
python3 generate_execution_time_report.py

# Token usage analysis
python3 generate_token_number_report.py

# Makespan analysis
python3 generate_makespan_report.py

# Repair iteration plots
python3 generate_repair_iteration_plots.py

# Scalability analysis
python3 generate_scalability_plot_report.py

4️⃣ ALAS Configuration Options

Workflow Types

• Full ALAS: Complete workflow with all features

  maple.run(with_rollback=True, validate=True, optimize=True, repair_iterations=5)

• No Repair: Disable repair iterations

  maple.run(with_rollback=True, validate=True, optimize=True, repair_iterations=0)

• No Validation: Skip validation steps

  maple.run(with_rollback=True, validate=False, optimize=True)

• No Optimization: Disable optimization

  maple.run(with_rollback=True, validate=True, optimize=False)

LLM Provider Selection

# Use specific LLM provider
maple = MAPLE(task_spec, model_type="gpt-4o")      # OpenAI
maple = MAPLE(task_spec, model_type="claude-4")    # Anthropic
maple = MAPLE(task_spec, model_type="gemini-2.5") # Google
maple = MAPLE(task_spec, model_type="deepseek-v3") # DeepSeek

5️⃣ Dataset Support

The system supports 5 dataset categories:

• DMU (Demirkol): 16 datasets with varying complexity
• TA (Real-world): 71 datasets from real manufacturing
• ABZ (Adams-Balas-Zawack): 10 classic job shop problems
• SWV (Swv): 20 benchmark datasets
• YN (Yamada-Nakano): 4 additional benchmark datasets

6️⃣ Expected Results

After running the experiments, you should see:

• ALAS Success Rate: 83.7% average across all datasets
• ALAS Optimal Rate: 100% for DMU/TA/ABZ/SWV/YN
• ALAS Execution Time: ~60 seconds per task
• ALAS Token Usage: Optimized efficiency

7️⃣ Troubleshooting

• API Key Issues: Ensure all API keys are correctly set in .env file
• Memory Issues: Use smaller batch sizes for large datasets
• Timeout Issues: Increase timeout values in configuration
• Dependency Issues: Ensure all packages are installed with pip install -r requirements.txt

✅ Final Thoughts

• If everything succeeds, all agents complete. ✅
• If any agent fails, local compensation or global replanning is attempted; if not possible, all completed agents roll back automatically, or by inputting a specific node. ✅
• Ensures multi-agent consistency in real-world applications (e.g., operating system, stock trading, planning, scheduling, transaction, or payments). ✅
