5. Suggestions for improving the MBSA methodology

Various avenues for improvement were raised during the course of this article. First of all, fault trees are tools widely used by engineers in the field of operational safety. They are generated by MBSA tools, but in an order that escapes any human-understandable logic. Indeed, when a RAMS engineer constructs a fault tree, it must be ordered in a logical, comprehensible and verifiable way, which is still far from being the case for a tree generated by MBSA tools. For the future, we can only hope that the engineers in charge of developing these tools will focus on the way fault trees are constructed. The generation of trees from MBSA models would then be fast and verifiable, allowing reliability engineers to do away with the tedious step of tree construction: putting this into practice would make the MBSA methodology more mature.

There is a need for harmonization...
