SKU Identification and Location Identification

Filed under: Inventory Management, WMS Systems — Tags: , — Ryan Murray @ 7:12 am

IF you want to have a successful inventory management system there are certain factors that you need to take into consideration.  Identification is the cornerstone of proper inventory management.  You must be able to identify each SKU as ell as where that SKU lives whether it be in a slot, bin, rack, shelf, or an area.  This is very similar to the address on your house or your business.  It lets everyone know where you dwell.  If you move then you will have to notify the post office of your change of address.  Your inventory management system must also have this capability.  The system must also be capable of assigning multiple locations for a particular SKU.  There may be an instance where a SKU may have more than one home within the warehouse and the inventory management system must be able to  account for this.  Tracking movements needs to be a simple process that can be accomplished in a reasonable amount of time.  By taking the above items into consideration your inventory management system will reduce labor associated with searching for individual products, and their locations within your facility.    It will also reduce unnecessary purchases  do to products that may have been misplaced or lost amongst the other items that you store in your warehouse.  Improved accuracy, less wasted labor, and an overall more efficient work environments stem from implementing a finely tuned inventory management system.

Lets take a closer look at how we can develop an effective locator system.  It begins with clearly marking the products with SKU identifiers.  These identifiers should contain units of measure and where the item is located or its location address.  Think of the location address like your home address.  Street, city, state, and zip correspond to your to your specific geographic location on a map.  An example of a warehouse address could consist of case, position, rack, and wing.  Now that item been clearly marked with the SKU and its address the inventory management system has to tie the address to the SKU.  When an item is moved from one location to another the system must be updated as soon as possible in order to maintain accuracy.  This can be accomplished through the use of bar  coding or by using RFID technology.  Identification can be alpha, numeric, or a combination of the two.  It has been found that workers typically make less mistakes when a numeric system is used vs. an alpha system.  It seems to be easier to match up numbers than to read words.  Bar coding scanners also help with the accuracy of identifying an item during the pick process.

The items that you store are are not the only things that need to have identification.  Positions within the warehouse must also be identified and clearly marked so that your staff can quickly recognize where a particular item is located.  Again, I refer to this like the address on your house.  If is is clearly visible from the street then it will be easier for your  guests to find your house.  This position address must specify where the item is located within your warehouse.  Just tying the sku to the position is not enough for an inventory system to be accurate.  The system has to be able to account for adds, deletions, as well as product moves.  Some organizations require real time updates this would require the use of mobile scanners/computers connected to some type of wireless or cellular network or through the use of RFID technology.

RFID – What is it?

Radio Frequency Identification (RFID)


Radio Frequency information is a technology used today to control supply chain management. This technology focuses on tracking pallets, individual items, and cases from the supply chain manufacturer to the customer itself. As the technology has evolved more and more applications for the utilization have become present. RFID was primarily used to track movement of items within a company, but today the technology has matured into a more economical and reliable service of tracking the movement of products from supply chains that network all around the world. RFID is a technology that is based on several components. To understand how RFID works we need to understand the technology itself and the information the technology allows us to work with.

The components that are required for an RFID system to operate include RFID tags, scanners, and antennas.  The tags come in two configurations, active and passive.  Active tags transmit information about the product via radio frequency.  Being that these tags are self powered, they continuously send information to antennas with in your facility.  Passive tags, on the other hand, need to pass by a scanning device in order for the information to be read.  A common example of a passive RFID tag would be the security tags placed on clothing in a retail store.  As a tag passes through the exit scanners an alarm sounds alerting the staff of a potential shoplifter.  This is one of the many applications of RFID technology that impacts us in our every day lives.  Active and passive tags enable organizations to quickly gather information regarding inventory counts and product movement through the supply chain.  Accuracy and speed are some of the most attractive features of using RFID technology.  What information is on the tags?

RFID information is based on the descriptive information about the product and the tracking information that follows the movement of a product through a supply chain. To make the movement of data all around the world more clear and easier to understand, a company named GS1 has developed a standard which is used worldwide that is based on a 14 digit numbering scheme named Global Trade Item Number or GTIN.  GTIN is a numbering scheme that has introduced the Electronic Product Code or EPC. EPC is composed of a version code that tells what version of EPC is being used, it has the manager code that tells what organization created the EPC number, it has the object class that defines the type of item or service, and the serial number that identifies a specific individual instance of the item or service.
