CARE®:
Computer‑Aided Reliability Engineering Suite for RAMS
Build right from the start
​​​​​
Unified FME(C)A, FTA, RBD, allocation & testability for electronic systems
CARE® is BQR’s system‑level RAMS platform. It unifies FME(C)A, Fault Tree Analysis (FTA), Reliability Block Diagram (RBD), reliability allocation, Monte Carlo, and Testability Analysis into a single, traceable environment. Import assemblies, parts, and failure data from Synthelyzer® / fiXtress® or Excel / CSV; define environments, distributions, and repair policies; then compute reliability, availability, and safety KPIs with auditable models and reports.
CARE® is On-Prem (not cloud).

Key Modules
FMEA / FMECA / RPN
Identify critical failure modes with customizable risk matrices; supports MIL‑STD‑882E, MIL-STD 1629a, SAE J1739, IEC 60812.
​
-
Sub Module:
Testability Analysis (TA) - Evaluate detection / diagnostics coverage to improve maintenance and system safety.
Mean Time to Repair (MTTR)
Define assembly failure modes and repair policies; remove and replace time. MIL-HDBK-472 compliance. Calculate MTTR and Mct.
Fault Tree Analysis (FTA)
Analyze complex scenarios, perform cut‑set calculations; IEC 61025 compliant; integrates with FMECA for model seeding.
Supports nested common causes.
Reliability Block Diagram (RBD) & MTBF Allocation
Top‑down reliability/availability allocation and calculation; IEC 61078 / IEC 61165 / IEC 61508 compliant; multiple distributions (Exponential, Weibull, Normal, Log‑Normal).
Account for periodic preventive maintenance.
-

Advanced Analysis & Modeling
Mission Reliability
RBD calculates mission reliability accounting for redundancies, periodic maintenance and repair policies.
Fault Isolation
Identify fault signatures and calculate the possibility to isolate the fault to LRU / SRU level.
Common Causes
Account for common causes and nested common causes in fault tree models for safety analysis of systems with high inter-dependability.
Models
Fault Tree:
Used for analysis of safety event probability and key contributors.
Markov model:
Used for reliability / availability analysis of complex cases where items affect each other, e.g. load sharing.
RBD Network:
Calculate availability / Reliability of complex topologies e.g. telecom network.
Core Benefits
Unmatched accuracy
Analysis linked to latest board / product design; instant updates when designs change.
Streamlined V&V
MTBF, life expectancy, and critical component identification at a glance.
Seamless ECAD integration
Accelerate reviews and safety analyses by integration with ECAD Synthelyzer.
Efficiency at scale
Faster RAMS workflows than generic spreadsheets; consistent templates and reports.
Dependable insights
Gain insights from FMECA & Testability Analysis regarding Built In Test efficiency, preventive maintenance and fault isolation.
Superior design quality
proactively remove single points of failure and optimize redundancy and repair policies.
HOW It Works
Unified Data Import
Ingest product tree, components and failure modes by importing from BQR’s fiXtress® into the core CARE database.
Model & Analyze
Validate data quality; build RBD, FTA and FME(C)A models; set distributions and repair strategies; run allocations and Monte Carlo.
Iterate & Optimize
Test What‑Ifs on architectures, redundancies, mission profiles and maintenance concepts to hit targets and budgets.
Design feedback & traceability
Publish prioritized risks, cut‑sets, weak blocks and recommended mitigations; maintain full revision traceability to design baselines.
Integration with BQR's Toolchain
CARE® operates as part of BQR’s integrated
RAMS reliability ecosystem:
Extracts schematic/BOM and product structures directly from ECAD.
Provides electrical/thermal stress and realistic MTBF per part to seed CARE models.
Precise circuit simulation
Together, these tools provide a digital‑twin reliability workflow from schematic to system safety and reliability.
