Design Description
Complex Dependency Diagram (TheDailyWTF)
Core
XML Parser - Utilizes external libraries to efficiently process XML files.
Validator - Ensures XML project and input files conform to the RELAX NG schema. Validation is integral to initialization, and values passing this process are not re-validated by subsequent components.
Settings - Manages analysis configurations for each run.
Project - Oversees program configurations, analysis inputs, and settings derived from a project file.
Analysis Input - Represents constructs such as models, fault trees, event trees, components, and events, closely aligning with the Open-PSA Model Exchange Format (MEF) architecture. The API is structured as if automatically generated by XML data-binding from the MEF schema, with added functionalities for model manipulation, validation, invariant enforcement, and analysis.
Initializer - Processes input files to build models, fault trees, event trees, common cause failures (CCF), and other analysis constructs. This phase validates both the input data and logic. Initialization adheres to configurations specified in the project file and command line. After initialization, analysis constructs remain unchanged.
Model Container - Acts as the top-level entity that uniquely owns all objects within the model, either directly or indirectly. Analysis inputs and containers persist as long as the parent model remains active.
Risk Analyzer - Operates on validated models with initialized fault trees, event trees, and other constructs to generate results based on user-defined settings. This phase follows initialization.
Analyzers - Perform specialized tasks within the Risk Analyzer, focusing on fault trees, event trees, CCF, uncertainty, and other areas. Shared utilities and functionalities ensure code simplicity and flexibility, adhering to Design by Contract and policy-based design principles.
- Fault Tree Analyzer - Analyzes individual fault trees with a single top event. It identifies primary events, intermediate events, and outputs such as minimal cut sets or prime implicants. Specialized facilities enhance analysis speed and efficiency.
- Probability Calculator - Uses Fault Tree Analyzer results to compute total probabilities and support other quantitative analyzers.
- Importance Analyzer - Calculates the significance of basic events using Probability Calculator results.
- Uncertainty Analyzer - Samples basic event probabilities via the Probability Calculator to derive statistical insights, including mean, confidence intervals, and distributions.
Reporter - Outputs Risk Analyzer results to XML files or streams.
Support Components - Includes logging utilities, XML stream handlers, and library extensions within the ext namespace.
