• GENERAL MANPOWER –SCBZ MACHINE SYSTEM WITH MARKOVIAN PRODUCTION GENERAL SALES AND GENERAL RECRUITMENT

T wo Manpower planning models with different recruitment patterns are studied. During the operation time a machine produces random number of products.  After the operation time, the sale time starts, which has one among two distinct distributions depending on the magnitude of production is within or exceeding a random threshold.  In this paper, the operation times have SCBZ property, production time has exponential distribution and the man power system, operation time, sales and recruitment times have general distributions. Joint transforms of the variables, their means and the covariance of operation time and recruitment time with numerical results are presented
