Dear Kwitonda,

You want to compare the reliability of the biotic index with what?

Or wanted to assess the reliability of the biotic indicator. And there is a nuance between index and indicator. An index is independent of time. For the assessment of the reliability of the biotic index you exploit the criterion that holds the index of biotic subjected to random variations. Measurement of the index can be based on the use of virtual prototypes tested on a virtual test bench that reproduces, mainly using computer aided design (CAD) tools, tests traditionally performed on Prototypes and compares the measurement associated with the criterion with a permissible and predetermined tolerance threshold. First, the proposed reliability indicator is an index. Then, an extension could be proposed to take account of the duration of the mission of the product.

Thanks
