This paper presents a profit-oriented shift scheduling approach for inbound contact centers. The focus is on systems in which multiple agent classes with different qualifications serve multiple customer classes with different needs. We assume that customers are impatient, abandon if they have to...

In stochastic lot sizing subject to dynamic and random demand, the minimization of operational costs is not the only conceivable objective. Minimizing the tardiness in customer demand satisfaction is no less important. Furthermore, the decision maker is interested in production plan stability....

Long-term throughput, as a key performance indicator of a stochastic flow line, is affected by numerous parameters describing the features of the flow line, such as processing time and buffer size. Fast and accurate evaluation methods for a given set of values for those parameters are a...

We study the problem to simultaneously decide on the structures and the schedules for an entire portfolio of flexible projects. The projects are flexible as alternative technologies and procedures can be used to achieve the respective project task. The choice between different technologies and...

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...

We present a stochastic version of the single-level, multi-product dynamic lotsizingproblem subject to a capacity constraint. A production schedule has tobe determined for random demand so that expected costs are minimized and aconstraint based on a new backlog-oriented Sigma-service-level...

We present a detailed analysis of the patient and resource scheduling problemin rehabilitation hospitals. In practice, the predominantly therapeutical treatmentsand activities which are prescribed for the patients are typically scheduled manually.This leads to rigid and inefficient schedules...
