recruitment model with tandem process

Recruitment process plays a vital role in an organization. This paper proposes a recruitment model with tandem processes which involves a pool of permanent & additional personnel for the recruitment of applicants to the various grades. Applicants arrive for the walk-in interview in a Poisson process and they are served exponentially by the recruitment board. The steady state distribution of the recruitment process is derived. Other performance measures such as the expected number of applicants, probabilities of the system states are obtained. Some special cases are discussed.
