Congested Storage Areas, Queues in the Aisles : 5 Military-Inspired Methods to Improve Material Flow in Industrial Logistics
During a military operation, a logistics staging area prepares a support convoy for departure to several units deployed on a mission. Packages arrive from different detachments. Some still need to be inspected, while others are ready to go and must be grouped by destination before being arranged in the correct loading sequence.
If pending packages, inspected items and loads ready for dispatch are placed in the same areas, teams end up moving materials several times. A pallet intended for a later departure may block access to priority loads, while forklifts and pedestrians cross paths in the aisles.
On an industrial site, storage and work areas must also be organised around the flow of materials: receiving, inspection, storage, order preparation and delivery to production workstations. Clearly defined areas and easy-to-follow routes help keep materials moving and reduce unnecessary handling.
Here are five methods inspired by military operations to improve storage organisation and material flow across an industrial site.
1. Start at the Point of Use
When a team prepares for an operation, resources must reach the people who need them at the right time. In a factory, the same principle means starting with the needs at the workstation and tracing the flow back to receiving. This is known as material flow mapping.
For each product family, identify:
Where it enters the site;
The inspection or preparation stages it goes through;
Its storage location;
Its picking point;
Its route to the workshop or production line.
This approach helps identify unnecessary movements, additional handling and waiting times. It also makes it possible to compare the planned route with what teams actually do, particularly when volumes increase or the organisation changes.
An effective storage layout should not be designed solely around the available space. It must support the actual flow of materials.
2. Give Each Area a Clear Purpose
An area used simultaneously for receiving, temporary storage, order preparation and returns quickly becomes difficult to manage. Products get mixed together, and teams may no longer know which items are available, awaiting processing or blocked.
Define clear purposes for the main warehouse and workshop areas:
Receiving and inspection;
Reserve storage;
Production order preparation;
Staging areas before delivery to production lines;
Returns and reusable packaging;
Non-conforming products or items awaiting a decision.
Each area's purpose should be visible on the shop floor through floor markings, signage or clearly identified storage locations. Teams should be able to understand quickly where to place an item and where to find the one they need.
When requirements change, temporary areas must also have clear rules: who can use them, for how long, and who is responsible for releasing them?
3. Reduce Cross-Traffic and Make Routes Safer
On an industrial site, pedestrian traffic, forklift movements, incoming materials and outgoing products can interfere with one another. A shorter route is not always safer or more efficient if several traffic flows cross it.
Observe actual movements on the shop floor:
Where do forklifts have to turn around?
Which passages are regularly obstructed?
Where do pedestrians and industrial vehicles cross paths?
Do drop-off areas block access to other locations?
Do material deliveries disrupt picking, dispatch, average travel times or operators' work, depending on the flow involved?
Based on these observations, clarify routes, traffic directions and designated drop-off areas. The rules must be easy to understand and consistent with the site's safety requirements.
Clearly defined routes reduce hesitation and improve coordination between warehouse teams, material handlers and production workshops.
4. Position Products According to How They Are Actually Used
Two items of the same size do not necessarily need to be stored in the same way. Their location may depend on picking frequency, destination, fragility or handling requirements.
Items used several times a day should be easy to access and, where appropriate, close to picking areas or points of use. Bulky, fragile or special-handling items require suitable storage locations. Slow-moving items can be stored elsewhere, provided they remain clearly identifiable and accessible.
Also consider the following:
High-value goods: Secure them and, where appropriate, store them in locations close to team leaders for easier oversight.
Fast- and slow-moving items: Place fast-moving items in easily accessible locations, using an appropriate layout to reduce picking time and improve productivity.
Products of similar value: Consider storing items of similar value near one another where appropriate, to reduce the potential financial impact of picking or identification errors.
Operators' movements: Take into account picking height, load weight, label visibility and the space needed to place or prepare products. A difficult-to-use location can lead to additional handling and increase the risk of errors.
The goal is to align the physical layout with actual usage patterns rather than keep a storage plan that no longer meets current operational needs.
5. Update the Layout Whenever Conditions Change
An area organised for a particular activity can quickly become unsuitable following an increase in volume, the introduction of a new product, seasonal demand, market or international developments, a production line modification or a change in packaging. If the layout remains unchanged, teams develop temporary workarounds that can eventually become permanent.
Plan major changes by assessing their impact on space requirements, routes and drop-off points. After making a change, update floor markings and location labels, then explain the new rules to the teams concerned.
Regular shop-floor checks can be based on a few simple questions:
Are aisles and access points clear?
Is each area being used for its intended purpose?
Are products in their designated locations?
Do observed routes match the planned layout?
Which problems keep recurring?
Repeated deviations are useful warning signs. They may indicate that a location is poorly chosen, an area lacks capacity or the planned operating model no longer matches the pace of production.
A Method You Can Apply Tomorrow
Choose one material flow, such as the journey of a raw material to a production line, and walk through it with the people responsible for carrying it out. Record the areas it passes through, waiting times, crossing points and temporary storage locations.
Flow stage | Area concerned | Problem observed | Action to test |
Receiving | Unloading area | Pallets block access to the inspection area | Mark out a dedicated staging area |
Storage | Reserve storage location | Products are difficult to identify | Improve location labelling |
Picking | Picking area | Orders being prepared are mixed with returns | Separate the areas |
Material supply | Aisle leading to the workshop | The route becomes congested during shift changes | Adjust the time slot or route |
Start by correcting one specific issue, then check how it affects movements and the teams' work. A useful improvement should simplify the flow without creating problems elsewhere.
A well-organised storage area makes materials easier to identify, move and deliver to production. Military-inspired methods can help guide this approach: define clear areas, plan routes and adapt the organisation as conditions change.
When storage areas become congested or internal material flows disrupt production supply, Task Force Logistics' operational consultants work alongside site management and logistics teams to strengthen day-to-day operations and help bring material flows back under control. Their presence on the shop floor helps stabilise routines and support production continuity.
