Abstract: | Most manufacturing takes place in the context of a supply
chain. Each station in the supply chain must not only
manufacture a product but also decide how much to produce.
This decision is influenced by the supply of
materials/components from the next station down in the supply
chain and the demand from the next station up. With the
advent of increased customization, inventory management is
increasingly becoming a critical issue in the manufacturing
process. In this paper we model the decision logic at each
stage of a supply chain system through the use of system
identification and PID controllers. The goal is to investigate
and manage the costs of manufacturing a product in the context
of a supply chain. It is assumed that the supply chain has wellunderstood
interactions between individual positions, allowing
for a focus on the ordering decision logic. A review of
ordering strategies is presented, and a discussion of the
difficulties in determining PID gains for human decision
makers is included. The results show a range of correlation
between the PID simulation and measured supply chain
inventories. This stems from a number of factors, which are
discussed. Additionally, ordering strategies to optimize the
supply chain are investigated. |
