- W2955002868 abstract "Abstract This paper extends strategic safety stock placement models under the guaranteed service approach (GSA) to incorporate tactical production smoothing. We propose a model to jointly optimize production capacity, production smoothing, and service times between all stages in the supply chain. Analysis of the model leads to several interesting findings. First, for certain service times, production smoothing is desirable to reduce both capacity and inventory costs. Second, inventory cost at a production stage is non-monotonous in its net service time and consequently quoting a large service time may increase costs at both the production stage and its customers. Third, safety stocks can be pooled at downstream stages only when production is not smoothed, while production smoothing necessitates holding safety stocks. The formulated problem is solved using a dynamic program and numerical experiments are conducted based on a real-world instance from the literature. Through these experiments, we show that integrating production smoothing in GSA models results in considerable savings, especially when capacity costs are neither too high nor too low relative to holding costs." @default.
