Gaining Control Of The Warehouse

Pet food distributor reduces labor, improves productivity with WCS.


Eliminates islands of automation: The WCS provides the middleware to connect a firm's WMS/ERP to the material handling equipment via a single interface. This provides a single point of monitoring and control for the entire warehouse, eliminating islands of automation.

Dynamic pick allocation: Traditionally, the WMS allocates the pick location hours before the actual pick happens and therefore it cannot react to problems on the floor. If the WCS selects the pick location, it can a make a "last minute" determination based on the current activity and operational status. If a pick zone is full or unavailable due to equipment failure, the WCS can select another location. This dynamic pick allocation helps balance the load on the system and increases productivity.

Cartonization: By analyzing the make-up of each order, the WCS selects the smallest possible size container, reducing shipping and dunnage costs. Cartonization also helps eliminate overweight boxes that can cause problems on the conveyor system.

Quality control: Customers are highly frustrated when they open the long-awaited package and find the wrong product was shipped. Distributors incur the additional cost of the return, as well as (and more importantly) the wrath of the customer. A WCS can help eliminate this problem in some industries by providing real-time order verification ensuring that the carton contents are correct for that order using an in-line scale. The WCS knows the expected weight of each order based on the items picked. Boxes outside of a user-defined tolerance can be diverted for manual quality control inspection.

Reduce theft and fraud: The WCS can help manage not only the product in the warehouse to reduce theft, but also help uncover and eliminate fraud. One company discovered that 80 percent of complaints for missing items were coming from a small number of their sales agents. Suspecting fraud, the company routed the suspected agents' orders for 100 percent quality control inspection, eliminating the problem.

Tracking: The real-time aspect of the WCS provides order status so that a company like Central Pet can track a product anytime, anywhere in the system.

Shipping: With a WCS, companies can dynamically change the ship method at the time of shipping, ensuring the most cost-effective method is used. Perhaps an order originally scheduled for a small parcel carrier actually weighs less than a pound, allowing it to be shipped parcel post.

If an important customer needs their package sooner, customer service can upgrade the service level while the order is in the process of fulfillment. The WCS prevents double shipment of orders, verifies that the package is sent to correct address, and eliminates common shipping errors, such as trying to ship a package to a P.O. Box via UPS.

System diagnostics and problem resolution: The WCS can consolidate operational statistics and diagnostics across the entire warehouse and provide improved visibility of equipment status and order tracking. These diagnostic capabilities help to identify the root cause of problems, such as incorrect carton routing or excessive recirculation. By identifying inefficiencies in the warehouse system, the WCS helps increase productivity and throughput.

Gaining Competitive Advantages

Central Pet's May translates the benefit of the new WCS in real bottom-line metrics quantifying that "it helped us to reduce 35 pullers in supply to 10 pullers in supply. But the biggest advantage was in the area of increased productivity, going from 25 to 30 lines per hour up to 100 or more lines per hour.

"Workers who had been working 14 to 15 hour days are now doing four 10-hour shifts," says May.

Central Pet's internal mechanism for continuous process improvement, while less formal than a Six Sigma methodology or an official Lean initiative, actually drives the pursuit of competitive advantages within the branches of the company.

"We have six branches and we rate each other. It's a continuous project that can have you up to number-one on one day and down to number six on another. Our WCS has helped us keep a competitive edge, even when up against our other branches," says May.
