Fifo lifo controller

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

• Lot Tracking Systems
• Shelf Life Databases
