MEAN TIME TO RECRUITMENT FOR A MULTIGRADE MANPOWER SYSTEM WITH SINGLE THRESHOLD, SINGLE SOURCE OF DEPLETION WHEN WASTAGES FORM AN ORDER STATISTICS

In this paper a multi graded organization in which depletion of man powers occur due to its policy decisions taken by the organization is considered. Four cases are constructed by taking exponential thresholds for the loss of man powers in each grade, where the loss of man powers (wastages) form an order statistics and inter decision times form i) an ordinary renewal process ii) an order statistics iii) a geometric process iv) correlated. Mean time to recruitment is obtained using an univariate CUM policy of recruitment (i.e) “The organization survives iff atleast out of n-grades survives in the sense that threshold crossing has not take place in these grades”. The influence of the nodal parameters on the system characteristics is studied and relevant conclusions are presented
