In this paper, we analyze the performance of call centers of financial serviceproviders with two levels of support and a time-dependent overflow mechanism.Waiting calls from the front-office queue flow over to the back office, if a waiting-timelimit is reached and at least one back-office agent...

This paper presents a linear programming approach to analyze and optimizeow lines with limited buer capacities and stochastic processing times. The basic ideais to solve a huge but simple linear program that models an entire simulation run of amulti-stage production process in discrete time, to...

Dieser Aufsatz analysiert das Standortplanungsproblem in der Ebene mit st¨uckweiselinearen bzw. st¨uckweise konstanten Transportkosten, die an praxisrelevanteFrachtsatztabellen angelehnt sind. F¨ur diese nicht-differenzierbarenTransportkostenfunktionen werden einstufige und dynamische...

This paper treats the problem of setting the inventory level of closed-loop owlines operating under the constant-work-in-process (CONWIP) protocol. We solve ahuge but simple linear program that models an entire simulation run of a closed-loopow line in discrete time to determine a production...

This paper analyzes the Steiner-Weber-Problem with piecewise linear or piecewise constant transportation costs. These non-differentiable cost functions are analyzed using different one-step and dynamic linearization methods, which are based on approximations via average and marginal costs. An...

This paper presents a linear programming approach to analyze and optimize flow lines with limited buffer capacities and stochastic processing times. The basic idea is to solve a huge but simple linear program that models an entire simulation run of a multi-stage production process in discrete...

In this paper, we analyze the performance of call centers of financial service providers with two levels of support and a time-dependent overflow mechanism. Waiting calls from the front-office queue flow over to the back office, if a waiting-time limit is reached and at least one back-office...
