Load Optimization Scenarios
Carton, pallet and vehicle optimization can add value to many areas in a business. Below are example scenarios where companies have used these technologies to reduce costs and gain a competitive edge. When looking at optimization, consider that where it is implemented can support subsequent processes.
Intercompany, Demand-Based and FTL Planning
Optimizing truck utilization upstream, before order creation can bring substantial savings. When you are not limited to planning based on predefined orders a high degree of utilization can be achieved. Consider using an optimizer to maximize transports based on demand, need-by-date, VMI or other priorities.
In the following example, the optimization algorithm was given a list of products that needed to be shipped over the course of a few days with varying priorities. The challenge for this company is that they have a high variance in weight through a broad product range. Think about heavy peanut butter and canned soups being loaded together with pasta and cereals. The algorithm can balance these factors achieving high volume and weight utilization, across multiple transports and assuring that the transports are within legal limits.
In the graphic, all priority 1 items (turquoise) are loaded in the first transport and priority 1 + 2 items (green) are loaded in the second transport. The first transport has a 98.2% weight utilization and 87.5 volume utilization. The second transport has a 99.4% weight utilization and a 90.3% volume utilization! The result was calculated in just a few seconds.

Order Management
Implementing pallet and load optimization at order entry can help businesses in several areas. First, it enables sales teams and customers to take decisions on order quantities based on accurate utilization. Truck and pallet utilization can be visualized to provide a clear view of capacity. Shipping quantity can be decreased if a transport is overloaded or increased to maximize utilization. ORTEC’s loading algorithm can even suggest additional product quantities to fill remaining space/weight on a transport.
This can lead to improved customer service and improved efficiencies in subsequent processes.
Additionally, having a clear view on transportation requirements at order entry can be used to support capacity planning for transportation, transportation procurement, and warehouse processes.

Transportation Planning
Consolidation of multiple deliveries on a transport accurately can be a difficult task. There are many goal conflicts that need to be considered to find the most optimal solution. Can all products be stacked on one another? What about individual customer requirements? Do certain products need to be held together or separated on a load? How about the delivery sequence in multi-stop trips? Is the optimal truck size and type being used for the load and customer? Will the truck or axles be overloaded? Can more products fit on the truck? Are the products staged efficiently for loading?
A pallet and load optimization solution can automate this planning process taking into account business rules and best practices from your seasoned professionals.

Warehouse
Using an optimizer for pallet and load optimization provides a sustainable way to produce optimal results in the Warehouse. We’ve been on warehouse walk-throughs before. In non-automated warehouses we are introduced to a veteran picker who shuffles through aisles placing products on pallets like a Tetris game. Forklift drivers zip around placing pallets in a pre-stage area before reorganizing products for proper loading. In most cases however the picking and loading quality is not consistent and quality can vary from employee to employee.
With an optimizer the planning process can be automated so that there are clear plans for pickers, forklift drivers and AWSs. Products can be staged correctly the first time, leading to fewer product movements. New and seasonal hires will have tools to build pallets and load trucks optimally based on predefined business rules.
Pallet and Loading optimizers can automate the planning process to produce optimal, standardized and sustainable results.
Picking
How to pick optimized pallets? Using an optimal pick sequence of course... For several customers, we have developed strategies to build optimal pallets based on their unique warehouse attributes. This includes things like sending layer build sequencing to automated layer pickers and building pallets in an optimal way based on the warehouse layout.
As mentioned in the previous section, having clear pallet and loading instructions for warehouse pickers and forklift drivers enables efficiencies in the warehouse for picking, staging and loading as well as standardization that is difficult to achieve without optimizers.
Carton Optimization
With more and more products being shipped with paper cartons, carton optimization has become a very important tool in reducing shipping costs as well as environmental impact caused by increased paper usage.
Given a set of different products, ORTEC’s 3D carton optimizer can select the most optimal size carton based on all available carton sizes. This capability can be implemented so that the selection is dynamic, with no user interaction. This will streamline the carton selection process and ensure that the most optimal carton is used for any shipment.

Reimagine Distribution
Companies use the power of our algorithms to achieve results that were difficult to imagine or were not able to be realized consistently in the past. We have numerous examples of how companies save substantially by using our algorithms in new ways. One example is the following case with 2 transports (before). In a new scenario, the company allowed the pallet algorithm to consider the trailer dimensions when optimizing pick pallets. The result is that pick pallets can be sized in an optimal way to fit into 1 transport (after optimization).
Image below: Before (colorized by product) & after (colorized by product).
A similar approach is used at another company. Instead of pick pallets however, the company allows the algorithm to depalletize full stock pallets (production pallets) so that certain products can be “loose loaded” on top of other pallets in their transports.
The first graphic illustrates the necessity of three transports without employing the top-loading technique. However, in the second graphic, the optimizer successfully condensed the same quantity of products into two transports. This was achieved by strategically depalletizing a minimal number of pallets and efficiently loading the products on top of the existing load.
Image below:Transportation of full “stock” pallets (before optimization)
Image below: Top loaded products: Optimizer depalletizes some full “stock” pallets so products can be top-loaded. The result is that all products can be loaded into 2 transports.
These are only some example of how optimizers have been implemented at companies. There are many more. Do you see other ways that a pallet and loading solution can add value to a business?
