Warehouse Consolidation & Slotting

Warehouse slotting is the process of organizing the inventory in a Warehouse Management System to maximize space and efficiency. It is a form of inventory management. A warehouse’s purpose is to act as a buffer between production and customer demand, thanks to Warehouse Management System (WMS) Software. This allows businesses to manufacture products and store them in a way that’s decoupled from immediate needs. 

With a need for a WMS System, businesses can fulfill customer orders faster and more efficiently, ultimately reducing costs.

WMS software uses a process called slotting to determine the optimal location for each item in the warehouse. Slotting takes into account various factors like item velocity (how often it’s picked), dimensions (cube size), weight, and product groupings. By strategically placing items, businesses can minimize picking times and optimize warehouse space utilization.

In essence, WMS software empowers businesses to leverage their warehouses as strategic assets, not just storage facilities. It’s all about bridging the gap between supply and demand smoothly and cost-effectively.

Warehouse Slotting Strategy

Warehouse slotting optimization strategies can help businesses reduce costs and improve efficiency in a number of ways, including:
  • Reduced replenishments: When products are placed in the most accessible locations, pickers can quickly and easily find and pick them, reducing the need for frequent replenishments.
  • More efficient travel paths: By grouping similar products together and placing them in easy-to-reach locations, businesses can minimize the distance that pickers have to travel, increasing their productivity.
  • Optimized space utilization and warehouse layouts: Slotting Warehouse can help businesses to make the most of their available warehouse space, reducing the need to expand or lease additional space..
Let’s see how warehouse management software (WMS) with slotting capabilities can truly supercharge your warehouse operations:

Boost order accuracy: Forget the mix-ups! WMS-powered slotting ensures the right items are always in the right places, minimizing picking errors and ensuring customers get exactly what they ordered.

Minimize product damage: Say goodbye to bumps and bruises! Slotting considers product dimensions and fragility, placing delicate items in secure, easily accessible locations, reducing the risk of damage during storage and retrieval.

Prioritize worker safety: Safety first! By strategically placing heavy or bulky items within easy reach, WMS (Warehouse Management System) slotting optimizes picking routes and minimizes awkward lifting, keeping your team safe and sound.

By incorporating these improvements, WMS systems empower businesses to not only store goods efficiently but also cultivate a warehouse that hums with accuracy, protection, and safety. It’s a win-win for business efficiency and employee well-being.

What Does Slotting Means in Warehouse Management?

Warehouse slotting is a complex process that requires careful planning and consideration. It is important to consider all of the factors that can impact slotting decisions, including:

  • Item velocities: This refers to the frequency at which an item is picked and shipped. Fast-moving items should be placed in the most accessible locations to minimize travel time and picking errors.
  • Dimensions (cube size): This concept refers to an item’s “cube size,” or the amount of space it occupies in the warehouse. Warehouse mgmt software and WMS software consider this crucial factor during slotting. They ensure larger items are placed in designated areas that can comfortably handle their size and weight, preventing potential damage or wasted space.
  • Weights: This refers to the weight of an item. Heavy items should be placed on lower shelves or on the floor to avoid accidents.
  • Product groupings: This refers to grouping similar items together. This can help to improve picking efficiency and reduce the risk of picking errors.
  • Warehouse layout: This refers to the overall layout of the warehouse, including the location of aisles, shelves, and other storage areas. The warehouse layout should be designed to minimize travel time and maximize picking efficiency.
  • Order picking and packing processes: This refers to the specific steps involved in picking and packing orders. The slotting strategy should be designed to support the order picking and packing processes in the most efficient way possible.

Importance of Warehouse Slotting

  1. Improved Product Handling
    • A critical consideration in a warehouse environment is preventing item damage during shipment or storage
    • Good inventory / items are stored correctly — perishable food is stored in refrigerated containers, for example.
    • This ensures that customers receive their items in good condition.
  2. Optimized Storage
    • Warehouse management systems requires businesses to spend money on storing items.
    • Businesses can store more products in the same amount of space, which can lead to lower warehouse storage costs and improved efficiency
  3. Seamless Fulfilment
    • Warehouse slotting makes it easier for employees to pick and pack items.
    • For example, you can reduce “traffic jams” by ensuring workers picking smaller items rarely have to wait while someone picks pallets using a forklift.
  4. Increased Safety
    • With warehouse slotting, facility managers can create an optimized pick order that places heavier items on the bottom of a pallet and lighter items on top.
    • That creates a safer pallet — one that’s not unbalanced or top-heavy — while minimizing the risk of product damage in transit.

Different Methods of Slotting

Random Slotting
  • Random slotting means items are assigned to pick zones instead of permanent pick locations.
  • If inventory in one slot depletes, then pickers are assigned to pick those items from another location within that zone.
  • Any incoming receipts transfer directly into pick zones, with little to no reserve inventory kept on hand.
Fixed Slotting
  • Fixed slotting means every item in the warehouse has a permanent bin location.
  • The rating for each bin is for a minimum and a maximum quantity of its assigned item.
  • If the bin becomes empty, it triggers a replenishment order from the reserve storage.
Macro Slotting
  • In macro slotting, the warehouse manager considers the arrangement of their pick zones.
  • In an environment where customers demand two-day shipping, this layout is critical — warehouses must feature high throughput designs with little congestion at the receiving or loading areas.
Micro Slotting
  • Micro slotting concerns with the arrangement of items and pallets within picking zones.
  • Micro slotting can significantly affect the warehouse ecosystem, primarily relating to worker health and safety.
  • For example, consistently placing heavier items on lower shelves might force workers to bend to pick them up — exposing them to repetitive stress injuries.

Benefits of Slotting

Reorganizing zones, or even an entire warehouse management system, can seem like a daunting and time-consuming project because we need to determine how to store inventory in an optimal way and move large amounts of inventory to different locations correctly, so it does not cause any issues during the picking process.

While the slotting process can be a major project that takes time and continuous improvement, it ultimately can benefit your business and positively affect the bottom line.

Here are a few ways that slotting helps:-

  • Faster picking and fewer picking errors

Proper slotting can improve picking accuracy by eliminating any possible confusion for the picker. Storing products that make the most sense for the picker such as by type, size, weight, etc., allows for faster picking. Workers can always know the location of items and how to get there without ever hunting through shelves.

  • More Storage Capacity

Slotting processes can help identify opportunities to increase storage capacity. Taking the time to optimize the warehouse means one can delay expanding and/or spend extra costs on an additional warehouse.

  • Reduce carrying costs

By optimizing warehouse space and improving processes, one can keep one’s overall carrying costs down rather than hiring more help or renting out more warehouse space.

  • Minimize Damages

Besides avoiding damage during transit or packing, a warehouse slotting strategy can also help avoid damage to stored items during handling and processing.

  • Increase Visibility

Good slotting helps improve employee productivity by allowing them to locate items immediately. This process helps managers and employees immediately understand when an item is not in the right place, which reduces the possibility of errors.

What is a Consolidation Warehouse?

A consolidation warehouse is a third-party storage facility where several small shipments are gathered together and sorted into groups based on destination, so that  each group can be sent out as one larger, consolidated shipment.Consolidation warehouses are a valuable tool for businesses of all sizes, but they are especially beneficial for businesses that ship a large number of small orders or that need to ship to multiple destinations.

Consolidation in warehousing that is operated by a third-party logistics (3PL) company that is responsible for merging small loads into large-size shipments.

Inventory Consolidation

  • For businesses operating through warehouses, it may be common to store stock of the same item across multiple bins.
  • This is because if one bin fills up, the stock will be distributed to the next free bin location, resulting in various quantities of the same stock suddenly being stored across multiple bins in the warehouse.
  • Although this might not, necessarily cause problems if small quantities of stock are picked when there are larger quantities or full pallets required to fulfil an order, issues can start to arise.
  • This is because pickers end up needing to collect the stock from multiple bins spread throughout the warehouse, rather than just one location ultimately leading to lowered productivity, reduced picking speeds and longer dispatch times, as staff travel longer distances to collect stock.
  • Therefore, for businesses regularly fulfilling large quantity orders, this inefficient way to amalgamate a single order for dispatch can drastically affect the number of orders leaving the warehouse, in turn leaving the business unable to meet order SLA requirements and leading to poor customer service.

FAQ

One example of warehouse slotting is to place the fastest-moving items closest to the loading dock. This reduces the distance that pickers have to travel to pick these items, which can improve picking efficiency and reduce order fulfillment times. Another example of slotting in the warehouse is grouping similar items together. This can make it easier for pickers to find the items they need and can also help reduce picking errors. Warehouse slotting can also be used to take into account the weight and size of items. For example, heavier items may be stored on lower shelves, while lighter items may be stored on higher shelves. This can help reduce the risk of accidents and injuries.
