In many factories, production problems don’t start on the shop floor, but in the material flow.
Production stoppages due to supply shortages, operators waiting for raw materials, unrecorded manual movements, stock discrepancies, or incomplete traceability are common situations in industrial environments where production and warehouse operations work in a disconnected way.
The reality is that efficiency no longer depends solely on having a well-organized central warehouse, but on how materials flow to the exact point of consumption within the plant. And this is where in-plant logistics plays a strategic role.

- and benefits of integrating MES, ERP, and WMS.
What is in-plant logistics?
In-plant logistics is the set of processes responsible for managing the movement, storage, and supply of materials within a manufacturing facility.
Its goal is to ensure that each production line has the right material, at the right time, with full traceability.
Why in-plant logistics and production must work in sync
Traditionally, companies have managed warehouse operations, production, and industrial supply chains through separate systems.
On one side, the ERP system handles planning and business management. On the other, WMS systems manage advanced warehouse operations. However, neither of them typically provides full real-time visibility of what is actually happening inside the plant.
The result is often translated into operational issues such as:
- Production line stoppages due to material shortages.
- Outdated stock information.
- Operators waiting for material replenishment.
- Lack of synchronization between production and warehouse.
- Untracked manual movements.
- Loss of material traceability.
- Excess intermediate inventory.
- Difficulties managing batches and production locations.
In this context, material management in the plant requires more than inventory control: it needs coordination of real industrial execution.
Differences between ERP, WMS, and MES in industrial in-plant logistics
| System | Main function |
|---|---|
| ERP | Business planning, purchasing, production, costing, and financial management |
| WMS | Advanced logistics management, storage, locations, picking, and shipping operations |
| MES | Real-time production execution and control of production and in-plant logistics |
One of the most common mistakes is to assume that an MES system and a WMS solve the same problem. In reality, they are complementary.
While the WMS optimizes warehouse operations, the MES connects production with the material flow within the plant.
In other words: the WMS knows where the material is. The MES knows when, where, and how it should be used in production.
That is why more and more manufacturers are choosing to integrate MES and warehouse systems to automatically synchronize materials, production orders, stock movements, and line replenishment.
How to synchronize production, warehouse, and material flow in real time
In dynamic industrial environments, the material flow is constantly changing.
The plant needs real-time visibility into:
- Which material is being consumed.
- Which batch is being used.
- Which line requires replenishment.
- Which product must be moved to the next operation.
- Which containers are available.
- What stock actually remains on the shop floor.
All of this must happen seamlessly, without paper, and without relying on calls or manual communication between production and the warehouse.
This is where an MES system provides operational visibility and execution capability.
How an MES system optimizes in-plant logistics and material management
An MES system enables the connection between production, warehouse, and operations to automate the material flow within the plant.
In the case of Mapex, our MES platform includes specific functionalities related to industrial supply chain, logistics, and warehouse management.
These capabilities cover everything from raw material supply and receiving to shipping, industrial inventory control, and full material traceability.
Warehouse management in production and material traceability
Mapex enables warehouse and location management through a complete hierarchical structure adapted to the industrial environment.
Its functionalities include:
- Configuration of warehouses and silos within the plant.
- Receipt of raw material orders.
- Dispatch of outbound orders.
- Reclassification of containers between locations.
- Supplier management and supplier–product relationships.
- Operations from work centers configured for receiving, shipping, or reclassification.
In this way, the system enables synchronization between warehouse and production without the need for intermediate manual processes.
Industrial inventory control, batch stock, and SSCC traceability
One of the biggest challenges in in-plant logistics is maintaining accurate, real-time inventory control.
Mapex includes advanced industrial stock control functionalities, including batch-level management in addition to traditional material-level tracking.
This enables:
- Automatic stock movements when production is reported.
- Quantity adjustments or corrections.
- Batch status changes management.
- Label reprinting.
- Full traceability ensured through SSCC.
Material traceability is no longer dependent on manual records and becomes fully integrated with production operations.
Line replenishment and real-time material requests
One of the most critical processes in manufacturing is line replenishment.
When material replenishment depends on calls, manual notifications, or constant supervision, the risk of production stoppages increases significantly.
To address this issue, Mapex includes a real-time material request system that directly connects the shop floor and the warehouse.
Operators can request raw materials from their workstation when they detect that supplies are running low, preventing production interruptions.
In addition, the system also allows:
- Requests for production pickups.
- Management of spare parts requests for maintenance.
- Automatic coordination of internal logistics movements.
Real case: logistics automation with AGVs at Campofrío
Campofrío Food Group has automated the request of raw materials, semi-finished products, and auxiliary materials from the shop floor to the warehouse using AGVs and Mapex.
The MES system automatically generates requests based on the Bill of Materials (BOM) of the manufacturing orders in the master production schedule.
In addition, once an operation is completed, the MES automates the material pickup request, instructing the AGV on the next operation or the destination warehouse.
The result is a much more agile, synchronized, and traceable material flow.
Real case: automatic material synchronization at La Farga
La Farga has also integrated Mapex with AGVs to automate internal material movements.
During copper tube manufacturing, when a production phase is completed, the MES automatically notifies the AGVs that the material is ready to be moved to the next operation.
This eliminates downtime, reduces manual handling, and improves synchronization between production processes.
Spare parts warehouse management integrated with industrial maintenance
In-plant logistics does not only affect production.
Within the maintenance module, Mapex also includes specific functionalities in its CMMS for spare parts warehouse management.
These capabilities include:
- Spare parts warehouse management.
- Suppliers and purchasing.
- Inventory management.
- Automatic purchasing with best-price calculation.
All of this is integrated with maintenance operations and also available through MapexWeb, Mapex’s mobility interface.
MES and ERP integration and connectivity with WMS systems
When logistics operations require advanced storage or distribution capabilities, Mapex can be integrated with specialized WMS systems.
The goal is not to replace the WMS, but to synchronize materials, stock, and movements with real execution on the shop floor.
This MES–WMS integration enables automatic coordination of:
- Production orders.
- Consumption and material movements.
- Material preparation.
- Line replenishment.
- Inventory and stock levels.
- Full material traceability.
In addition, Mapex can be integrated with ERP systems such as SAP to import and export information related to materials, orders, BOMs, stock, or inventories.
Real case: MES, ERP, and WMS integration at Angulas Aguinaga
Angulas Aguinaga, a company specialized in modern seafood solutions and creator of brands such as La Gula del Norte and Krissia, has integrated Mapex’s MES platform with its ERP and WMS systems.
In this case:
- The ERP sends production orders to Mapex.
- When orders are released to production, the MES communicates the information to the WMS.
- The WMS automatically prepares the required materials.
- Materials are delivered directly to the selected locations at the production line.
Thanks to this production–warehouse synchronization, the company achieves faster replenishment and improved operational efficiency.
MES and industrial logistics integration: a key enabler for the connected factory
Industrial digital transformation is pushing factories to increasingly connect all operational areas.
Today, efficiency no longer depends solely on optimizing production or warehouse operations in isolation. The key lies in real-time coordination of production, in-plant logistics, materials, traceability, stock movements, and the industrial supply chain.
That is why more and more companies are integrating MES and WMS systems to gain a synchronized, end-to-end view of industrial operations.
