Abstract: In any organization the exit of personnel occurs, especially once the policy decisions relating to pay, perquisites and targets are proclaimed. In real time, once the exit of personnel happens, the recruitment cannot be introduced as a result of its time overwhelming and costly. Frequent recruitments are also not fascinating. Thus, the recruitment is made solely once the additive loss of manpower on sequent occasions cross the level referred to as threshold. Applying shock model approach, many stochastic models with bivariate policy of recruitment are constructed. In this paper, the explicit expression for the long - run average cost per unit time is derived when (i) survival time process is a geometric process and (ii) the threshold for the loss of manpower contains two components namely the level of wastage which can be allowed and the manpower due to extra time work. Numerical illustrations are additionally provided.
