N2 - This paper presents the main results of studies which include both the search for new observablessensitive to novel physical phenomena expected in the formation of baryon rich densematter formed in the collisions of heavy ions at NICA, and some practical solutions for selectionof events with given mean energy density relevant to the number of binary nucleon-nucleoncollisions. The behavior of strongly-intensive observables in the ranges of rapidity and momentaavailable for measurements at the MPD is presented, taking into account the response of theMPD experimental setup and reconstruction in the MpdRoot package. Methods of correctionon track losses and inaccurate identification of particle species are discussed. The applicabilityof the standard Glauber model for the selection of centrality classes at the energies of the NICAcollider is being critically reviewed. On the basis of MC simulated data and in accordancewith the criteria of the subsequent physical analysis, the possibilities of the efficient selection ofevents using the new fast detector system of beam-beam collisions monitoring are also brieflydiscussed
