Q: What are the most important technical criteria for choosing a reliable product?

A: There are four main indicators:

• MTTF (Mean Time to First Failure):

This measures the lifespan of non-repairable components.
It is calculated as the average failure times of identical samples.
It is recommended to replace the component before reaching this average; a higher number is better.

• MTTR (Mean Time to Repair):

This is the time between fault detection and the system returning to normal operation, a shorter time is better.

• MTBF (Mean Time Between Failures):

This indicates reliability and a low frequency of failures that negatively impact performance, a higher number is better.

• MDT (Mean Time Downtime):

This indicates the duration of system downtime; a lower number is better.

Q: Why are these criteria important in product selection?

A: Frequent failures lead to significant losses, such as repeated brake failures in a car, prolonged downtime of a queue management system in a bank or call center, or even risks in medical devices.

Choosing a product with a high MTBF and a low MTTR ensures business continuity, customer satisfaction, and cost reduction.

Q: How does Q-Linker implement these conditions?

A: Q-Linker is committed to selecting high-quality components and spare parts from reliable sources, which extends service life, simplifies maintenance, and increases MTBF while minimizing downtime, providing reliable and efficient equipment.

Q: What is the main practical advice?

A: Don't buy a product based solely on price. Carefully evaluate MTTF, MTBF, and MTTR, and replace critical components before they reach the end of their service life to avoid unexpected failures and losses.
