| Abstract: | The proportional expected inactivity time model(PEITM) is introduced and some of its properties are discussed.The results show that reversed hazard rate(RHR) ordering and expected inactivity time(EIT) ordering are preserved under PEITM.The random comparison between RHR and EIT ordering is given with the total variables in different PEITM. |

| Keywords: | reversed hazard rate expected inactivity time stochastic ordering |
