vamseeachanta Risk Assessment
When to Use This Skill
Use this skill when you need to:
- Perform Monte Carlo simulations for uncertainty quantification
- Calculate system reliability and failure probabilities
- Conduct sensitivity analysis to identify critical parameters
- Create risk matrices for hazard assessment
- Perform probabilistic design and analysis
- Quantify uncertainties in marine operations
- Make decisions under uncertainty with risk metrics
- Validate designs against reliability targets
Core Knowledge Areas
1. Monte Carlo Simulation
Basic Monte Carlo framework:
import numpy as np
from scipy import stats
from dataclasses import dataclass
from typing import Callable, Dict, List, Tuple, Optional
import pandas as pd
@dataclass
*See sub-skills for full details.*
### 2. Reliability Analysis
Calculate reliability and failure probability:
```python
def calculate_reliability(
response_data: np.ndarray,
limit_state: float,
mode: str = 'less_than'
) -> dict:
"""
Calculate reliability from Monte Carlo results.
*See sub-skills for full details.*
### 3. Sensitivity Analysis
Identify critical parameters:
```python
def sensitivity_analysis_correlation(
inputs: Dict[str, np.ndarray],
output: np.ndarray
) -> pd.DataFrame:
"""
Sensitivity analysis using correlation coefficients.
*See sub-skills for full details.*
### 4. Risk Matrices and Hazard Assessment
```python
from enum import Enum
class Severity(Enum):
"""Consequence severity levels."""
NEGLIGIBLE = 1
MINOR = 2
MODERATE = 3
MAJOR = 4
CATASTROPHIC = 5
*See sub-skills for full details.*
### 5. Extreme Value Analysis
```python
from scipy.stats import genextreme
def fit_extreme_value_distribution(
data: np.ndarray,
method: str = 'gev'
) -> dict:
"""
Fit extreme value distribution to data.
*See sub-skills for full details.*
