Round 12

Spare-Parts Replenishment Model

A distributed operations network supports several service sites that rely on a shared inventory of critical spare parts. Stockouts can cause extended downtime, while excess inventory ties up storage space and risks obsolescence. Demand is uneven, supplier lead times vary, and site managers currently use inconsistent ordering practices. The goal is to improve equipment availability without creating excessive inventory, administrative effort, or dependence on a single central warehouse. The decision should account for forecast uncertainty, emergency responsiveness, transportation workload, storage limits, and the ability to scale as the network grows.

E Use centralized replenishment: one planning team owns forecasts, sets reorder points, and ships parts to sites according to standardized service targets.
