Abstract: In this paper, under some mild conditions, precise large deviations for partial sums of negatively associated random arrays in multi-risk models are investigated. The obtained results extend some known ones, and we find out the asymptotic behavior of precise large deviations is also insensitive to negatively associated structures in multi-risk models. \newcommand\fundinfoThis work was supported by the National Natural Science Foundation (10771070), Talents Youth Fund of Anhui Province Universities (2011SQRL012ZD) and the 211 Project of Anhui University (2009QN020B)
