FIFO-LIFO Controller

Overview

The FIFO-LIFO Controller is an automated skill that manages inventory rotation to ensure proper product flow based on expiration dates, production dates, or receipt dates. It enforces First-In-First-Out (FIFO), First-Expired-First-Out (FEFO), or Last-In-First-Out (LIFO) policies and manages lot tracking and shelf life compliance.

Capabilities

  • FIFO Enforcement at Pick Time: Ensure oldest inventory is picked first based on receipt or production date
  • FEFO (First Expired First Out) Management: Prioritize inventory with nearest expiration dates for picking
  • Lot and Batch Tracking: Maintain complete traceability of inventory by lot, batch, or serial number
  • Expiration Date Alerting: Generate alerts for inventory approaching expiration thresholds
  • Shelf Life Calculation: Calculate remaining shelf life and predict expiration risk
  • Product Hold Management: Manage inventory holds for quality, recall, or compliance reasons
  • Compliance Documentation: Generate documentation for regulatory compliance and audit requirements

Tools and Libraries

  • WMS APIs
  • Lot Tracking Systems
  • Shelf Life Databases
  • Compliance Management Tools

Used By Processes

  • FIFO-LIFO Inventory Control
  • Cycle Counting Program
  • Receiving and Putaway Optimization
