An organization with two grades subjected to loss of man-power due to the policy decisions taken by the organization is considered. Three mathematical models are constructed using an univariate recruitment policy, based on shock model approach involving optional and mandatory thresholds for the loss of man-power in each grade. The system performance measures namely mean and variance of time to recruitment are obtained for all the models when (i) the loss of man-hours form a sequence of independent and identically distributed exponential random variables (ii) the inter-decision times form an order statistics according as the optional thresholds follow exponential or extended exponential and the distribution of mandatory thresholds possess SCBZ property. The analytical results are numerical illustrated and the influence of nodal parameters on the performance measures is also reported.
