Title: 	Simultaneous lotsizing and scheduling
Author: Prof. Herbert Meyr, Technical University of /Darmstadt/
Date: 	Tuesday, May 11th 2010, 13h00 (INESC Porto anfiteatro)
Abstract: 	 
	Simultaneous lotsizing and scheduling (SLS) is necessary in
       situations where deterministic dynamic demand of several
       products has to be met on one or several parallel, capacitated
       productions lines, underlying sequence-dependent setup costs
       or setup times. Such prerequisites are, for example, often
       predominant in consumer goods industries with make-to-stock
       production.

       The talk gives a brief overview of mixed-integer-programming
       models for SLS, but mainly concentrates on the General
       Lotsizing and Scheduling Problem for Parallel production Lines
       (GLSPPL). After explaining the "traditional" heuristic
       approach of combining local search with dual reoptimization
       some recent extensions and enhancements are discussed which
       were necessary to tackle a real world case in health care
       production. It is shown how dual reoptimization can be adapted
       to respect time-varying production coefficients. Furthermore,
       a decomposition approach to solve larger-scale problems is
       sketched.
