We consider the problem of dynamic admission control in a multi-class Markovian loss system receiving random batches, where each admitted class-i job demands an exponential service with rate μ, and brings a reward ri. We show that the optimal admission policy is a sequential threshold policy with monotone thresholds.

Abstract: In the paper we deal with a Markovian queueing system with two heterogeneous servers and constant retrial rate. The system operates under a threshold policy which prescribes the activation of the faster server whenever it is idle and a customer tries to occupy it. The slower server can be activated only when the number of waiting customers exceeds a threshold level. The dynamic behavi...

In this paper, we propose a closed-loop structure of intelligent policy system for wireless channels allocation of IA (information appliance). At first, an approximated mathematical model and optimality equations of dynamic programming is defined. Then, the optimal control policy for this model can be computed via the method of successive approximation. Based on this algorithm for computing opt...

We formulate the call admission control problem for a single link in an integrated service environment as a Markov Decision Problem. In principle , an optimal admission control policy can be computed using methods of Dynamic Programming. However, as the number of possible states of the underlying Markov Chain grows exponentially in the number of customer classes, Dynamic Programming algorithms ...

BACKGROUND Title VI of the 1964 Civil Rights Act prohibits federal funds recipients from providing care to limited English proficiency (LEP) persons more limited in scope or lower in quality than care provided to others. In 1999, the California Department of Mental Health implemented a "threshold language access policy" to meet its Title VI obligations. Under this policy, Medi-Cal agencies must...

In a number of service settings, customer waiting, admission control, and speedup of service rates can occur during periods of congestion. For example, in a healthcare setting, this means that patients who require care may be sent to other, less ideal service outlets or hospital units. As expected, this comes at a cost to patient outcomes. In this work, we examine a multi-server queueing system...

the study investigated challenges to soil erosion control measures among farmers in anambra state, nigeria. purposive, multistage and random sampling techniques were employed in selecting a sample size of two hundred and forty (240) respondents. structured interview schedule was used for data collection. frequency counts, percentage, mean scores and factor analysis were used for data analysis. ...

the ultimate goal of monetary policy is to achieve price stability and high output. in this regard, central banks usually change the interest rate, liquidity, and money base in order to apply monetary policies. the john b. taylor rule is one of the rules known in the transmission of monetary policy.[1] based on this rule and given the output gap and inflation gap, the central bank increases or ...
