K. Usha, A. C. Tamil Selvi*, R. Ramanarayanan

Abstract


Manpower system is getting much more attention these days due to the absolute neccessity of manpower for any business. A system in which employees leave the organization during busy period and new employees are recruited after the busy period. The project completion time is busy period. Two models are discussed. In Model A, the busy period has general distribution and the inter departure time of employees has exponential distribution and in Model B the busy period has exponential distribution and the inter departure time of employees has general distribution. The recruitments are made with inter-recruitment times in accordance with Geometric process. Joint Laplace transforms of busy period and recruitment time, their means and co-variance are obtained. Numerical results are presented.


Keywords


Manpower system, Loss of manpower and recruitment, Geometric process, Joint transform.
