This paper presents a generic modeling framework to simultaneously decide about production quantities and maintenance operations for a capacitated resource facing a dynamic demand for di erent types of products. As the resource needs to be setup for each speci c type of product, a lot-sizing...

This paper presents a new algorithm for the dynamic Multi-Level Ca-pacitated Lot Sizing Problem with Setup Carry-Overs (MLCLSP-L). TheMLCLSP-L is a big-bucket model that allows the production of any num-ber of products within a period, but it incorporates partial sequencing of theproduction...

This paper presents an optimization-based solution approach for the dynamicmulti-level capacitated lot sizing problem (MLCLSP) with positive leadtimes. The key idea is to solve a series of mixed-integer programs in an iterativefix-and-optimize algorithm. Each of these programs is optimized over...

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...

This paper presents a profit-oriented shift scheduling approachfor inbound contact centers. The focus is on systems in which multiple agentclasses with different qualifications serve multiple customer classes with differentneeds. We assume that customers are impatient, abandon if they haveto...
