  This comparison aims to present different functionalities provided by two
software tools among the most used for production availability analyses: MAROS
(developed by DNV) and GRIF/BStok (developed by Total). The different
functionalities are presented and compared through tables. Then, a case study
allows comparing the results obtained by the two tools. MAROS and GRIF/BStok
both provide production availability analyses that meet industrial needs. While
the use of MAROS brings to the user more "conviviality", a drawback is the
"black box" aspect that results from it. BStok, thanks to the underlying
exploitation of Petri nets, supplies more modeling flexibility in exchange of
higher expertise.
