2. Limits of the analytical method
2.1 Taking probability density laws into account
If we examine the method presented above, it is clear that it is a variance propagation method. The problem of distribution arises at two levels: firstly, when the balance of sources of uncertainty is studied, and secondly, when the expanded uncertainty is determined.
For each component, either a Type A or Type B study is carried out.
For type B, the problem is particularly clear. We qualify a dispersion. Assuming a uniform probability density law, we pass to a variance by dividing the dispersion by . This division by
