Estimation of Variance of the time to recruitment under two sources of depletion

In this paper, the problem of time to recruitment is studied using a univariate policy of recruitment for a two grade manpower system in which attrition which leads to loss of manpower takes place due to two sources of depletion. A stochastic model is constructed and the variance of the time to recruitment is obtained when the inter-policy decision times for the two grades form same renewal processes but the inter-transfer decision times form the two different renewal processes. The results are illustrated and specific conclusions are given on the influence of parameters over the performance measures.
