The Bayesian approach is a stochastic method, allowing to establish trend studies on the
behavior of materials between two periods or after a break in the life of these materials.
It naturally integrates the inclusion of the information partially uncertain to support in
modeling problem. The method is therefore particularly suitable for the analysis of the
reliability tests, especially for equipment and organs whose different tests are costly.
Bayesian techniques are used to reduce the size of estimation tests, improving the
evaluation of the parameters of product reliability by the integration of the past (data
available on the product concerned) and process, the case “zero” failure observed,
difficult to treat with conventional statistical approach. This study will concern the
reduction in the number of tests on electronic or mechanical components installed in a
mechanical lift knowing their a priori behavior in order to determine their a posteriori
behavior.
