I have activelly participated to the development of 3 software tools:
  • -MARS (Maintenance Assessment of Repairable Systems) is a freeware tool for Maintenance Assessment of Repairable Systems. MARS implements imperfect maintenance models and estimates jointly the effects of ageing and maintenance (preventive and/or corrective) efficiency on real data sets from field feedback. MARS has been developed in cooperation with EDF R&D.
  • -VAM (Virtual Age Models) is an R package for wear out and maintenance effect analysis. We are developing VAM since 2016 with R. Drouilhet. The package is available from github.
  • -VirtualAgeModels is a Julia package wich aims to replace VAM package. I have participated to the development of the package with R. Drouilhet.
