1. What is System Reliability Calculation?

System reliability calculation determines the overall reliability of a system composed of multiple components in series. It represents the probability that the entire system will function properly given the individual component reliabilities.

2. How Does the Calculator Work?

The calculator uses the series system reliability formula:

Where:

• \( R_s \) — System reliability (decimal)
• \( R_i \) — Reliability of individual components (decimal, 0-1)
• \( \prod \) — Product of all component reliabilities

Explanation: For components in series, the system fails if any single component fails. The overall reliability is the product of all individual component reliabilities.

3. Importance of System Reliability

Details: Calculating system reliability is crucial for engineering design, quality assurance, risk assessment, and maintenance planning. It helps identify weak points in systems and optimize component selection.

4. Using the Calculator

Tips: Enter component reliabilities as decimal values (0-1) separated by commas. All values must be valid probabilities between 0 and 1.

5. Frequently Asked Questions (FAQ)

Q1: What is the range of valid reliability values?
A: Reliability values must be between 0 and 1, where 0 means certain failure and 1 means certain success.

Q2: How does series configuration affect system reliability?
A: In series systems, the overall reliability is always less than or equal to the reliability of the least reliable component.

Q3: What about parallel systems?
A: This calculator is for series systems only. Parallel systems have different reliability calculation methods.

Q4: Can I use percentages instead of decimals?
A: No, the calculator requires decimal values. Convert percentages by dividing by 100 (e.g., 95% = 0.95).

Q5: What if my system has mixed configurations?
A: For complex systems with both series and parallel components, more advanced reliability block diagram analysis is needed.
