Warehouse Optimization Challenges

Most of the challenges that arise in warehouse optimization are related to errors, inefficiency, and lack of transparency. Many warehouse managers correct these challenges with warehouse management systems, automated material handling systems, barcoding, and automated data collection.

As Apptricity CEO Tim Garcia notes, there are five common warehouse problems that pose challenges to warehouse optimization: inventory accuracy, inventory location, space utilization and warehouse layout, redundant processes, and picking optimization.

Here’s a in-depth look at each challenge:

• Inventory accuracy – Companies often do not know what they have in stock and have too little visibility into their warehouses when they lack an automated system
• Inventory location – Without accurate insight into inventory location, pickers cannot work efficiently, which results in slower loading processes and backups in dock scheduling
• Space utilization and warehouse layout – If storage systems and warehouse racking is not optimized, space required to house inventory and labor needed inside the warehouse increase
• Redundant processes – Redundant processes and multiple touches hurt a company’s bottom line and are inefficient
• Picking optimization – Too many warehouses lack common routes for picking items for shipment because their manual processes are inefficient.
