Lot sizing and scheduling — Survey and extensions <s> Case descriptions <s> An outline of the tire production process is given. A planning model is discussed and an application is made to the planning of tire production both long and short term. Planning for finished tires, green tires and for components is included as the model is developed. A multi-item production planning program is presented for finished tires and this is expanded to an assembly model with precedences for green tires and for components. <s> BIB001 </s> Lot sizing and scheduling — Survey and extensions <s> Case descriptions <s> SUMMARY This paper summarizes the development and implementation of a large-scale, multi-objective, lot-sizing model for scheduling tablet pharmaceuticals in a serial production system. The model places multiple resource capacity constraints on production at various stages of the manufacturing process and explicitly considers resource set-up times to ensure the generation of a feasible schedule. The multi-period model uniquely allows for variable lot sizes by stage and by period, subject to integrality restrictions arising from the technological nature of the multi-stage process. An integer goal programming approach is used for determining non-dominated solutions to the multi-item problem. The implementation and utilization of the model by an international manufacturer of pharmaceuticals is described, and model results are presented and discussed. <s> BIB002
To underscore the practical importance of (multilevel) lot sizing and scheduling, we enumerate some real-world reports demanding for methods to be applied. A case at Eastman Kodak Company and an elaborate analysis attached with results of a simulation of this case can be found in  . Another case at Owens-Corning Fiberglas Corporation is described in  . Mathematical models of cases can be found in BIB001 (tire production) and BIB002 (pharmaceutical industry).
