Comparison of two tools for production availability analyses: MAROS and GRIF/BStok

TL;DR

This paper compares two widely used production availability analysis tools, MAROS and GRIF/BStok, highlighting their functionalities, differences, and case study results to guide industrial tool selection.

Contribution

It provides a detailed comparison of MAROS and GRIF/BStok functionalities and demonstrates their performance through a case study, aiding practitioners in choosing suitable tools.

Findings

Both tools meet industrial needs for availability analysis.

MAROS offers user-friendly interface but less modeling transparency.

GRIF/BStok provides flexible modeling via Petri nets, requiring more expertise.

Abstract

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.
