The LHCb experiment is a fully instrumented forward spectrometer designed for
precision studies in the flavour sector of the standard model with proton-proton
collisions at the LHC. As part of its expanding physics programme, LHCb collected data also during the LHC proton-nucleus collisions in 2013 and 2016 and
during nucleus-nucleus collisions in 2015. All the collected datasets are unique,
due to the peculiar pseudo-rapidity range not covered by any other LHC experiment. Furthermore, in 2015 LHCb commissioned the internal gas target SMOG,
becoming the only LHC experiment with a programme of fixed target physics.
Any of these particular collision conditions required a different operational setup,
as well as dedicated simulation production based on heavy-ion Monte-Carlo event
generators and interface extensions of the standard LHCb simulation framework.
In this talk, we present the work done to implement such a variety of simulation
productions for heavy-ion collisions, and to validate the produced samples. The
future perspectives of the heavy-ion collision simulations at LHCb will also be
