Embodiments of the present disclosure provide systems and methods for implementing a field supply chain logistics system for managing spare parts inventory. In one embodiment, the method comprises: identifying locations for field service locations (FSLs) field warehouses for the spare parts, based on time or distance windows to deliver the parts to the field locations each FSL serves; collecting and validating data to compute optimal field inventory levels and minimum inventory levels for non-field warehouse, the non-field warehouse including central stock; physically setting up FSLs so that the FSLs functions as field warehouses and receive plug requests; generating optimal inventory profiles; opening FSLs for service; conducting plug inventory to retrieve plug excess and deploy new levels; and conducting after implementation review to verify that processes are being followed as expected and document lessons learned.
