We consider a queueing loss system with heterogeneous skill based servers with arbitrary service distributions. We assume Poisson arrivals, with each arrival having a vector indicating which of the servers are eligible to serve it. An arrival can only be assigned to a server that is both idle and eligible. Assuming exchangeable eligibility vectors and an… (More)

The first significant objective of this study is that, for the ease of production and resource planning, the rework cycle has to have the same length as the other cycles. The other objective is that the number of rework cycles be as small as possible, because of changeover costs needed for going from normal production to rework as well as special attention… (More)

Intersymbol interference (ISI) of the radio propagation through multipath fading channels and nonlinear distortion are major factors that limit the performance of communication systems. In this paper we introduce a new blind adaptive per tone Hammerstein equalizer for OFDM systems. In this scheme, we compare the performance of the blind adaptive per tone… (More)

In this paper we consider an imperfect production system which produces good and defective items and assume that defective items can be reworked. Due to the nature of rework process we do not restrict the rework rate to be equal to normal production rate or constant and assume that it is a random variable with an arbitrary distribution function. We also… (More)

Abstract In this paper we consider a system consisting of a retailer, a supplier with a single processing unit, and a repair center. We assume that the retailer faces a Poisson demand, his ordering cost is zero or negligible, and for his inventory control he applies one-for-one ordering policy, that is, as soon as a demand arrives he orders one unit to the… (More)

We consider an M/G/∞ model with exponentially distributed setup times. Arrivals result in an off server starting a setup. Upon completing a setup, a server begins serving a waiting customer. Upon completing service, with probability p the server becomes eligible to serve another waiting customer. Among other things, we show, in steady state, that the number… (More)

In this paper we consider a two- echelon inventory system consisting of one supplier and a number of retailers with independent Poisson demand. Unsatisfied demands in retailers are lost and it is assumed that there is a constraint on total lost sales for the system. Each retailer applies a new ordering policy called one-for-one-period ordering policy for… (More)
