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...
