medini analyze supports an Aviation/Aerospace safety domain profile that implements the recommended practices SAE ARP 4754A and ARP4761. This comprises currently the following tool aspects:
Functional Hazard Assessment (FHA)
Safety Requirements have a Development Assurance Level (DAL)
SysML Functions/Activities support a Function Development Assurance Level (FDAL)
SysML parts/blocks/ports receive a Item Development Assurance Level (IDAL)
Risk time model for FTA
Further additions and refinements will follow in subsequent releases.
The default Aviation project template consist of the following package structure:
Function Design
This package supports the functional architecture and high-level design using SysML to define the aircraft or system for subsequent analysis. Usually the functional dependencies should be modeled here and their Functional Failures (FF).
Functional Hazard Assessment
This package supports the creation of the FHA and Failure Conditions (FC). Sub-packages might be created for Aircraft FHA and System FHA in this scope to distinguish those assessment levels.
Safety Requirements
The safety requirements hierarchy of functional, technical, HW/SW requirements can be modeled in this package using DALs at safety requirements.
System Design
System Design models are managed in this package. They can be created or imported as needed. There are three default sub-packages which have the same capabilities:
Architecture Models
Hardware Models
Software Models
Safety Analysis
All safety analysis such as FMEA, FMES, and FTA are stored in this sub-structure:
FMEA
FMES
FTA
CCA
This folder is meant to manage the Common Cause Analysis (CCA) by checklists or other artifacts.
