ESTIMATION OF MEAN TIME TO RECRUITMENT FOR A TWO GRADED MANPOWER SYSTEM WITH TWO THRESHOLDS, DIFFERENT EPOCH FOR EXITS AND EXPONENTIAL INTER-DECISIONS UNDER CORRELATED WASTAGE.

In this paper, an organization with two grades, subjected to exit of personnel due to policy decisions taken by the organization is considered. As the exit of personnel is unpredictable a univariate recruitment policy involving two thresholds one is optional and other is mandatory is suggested to enable the organization to plan its decision on recruitment. Assuming that the policy decisions and exits occur at different epochs, a stochastic model is constructed and the mean time to recruitment is obtained when the loss of manpower at each decision epoch are identically distributed constantly correlated and exchangeable exponential random variables, thresholds follows independent and identically distributed exponential random variables , the inter-policy decision times form independent and identically distributed exponential random variable and inter-exit times form an ordinary renewal process.
