From buffer storage for fresh logistics and refrigerated logistics warehouses to automated AI high-bay warehouses and pallet warehouses

Modern logistics is faced with the challenge of making complex supply chains efficient while at the same time meeting the growing demands for speed, precision and sustainability. Innovative storage solutions play a key role. From simple buffer storage for fresh and refrigerated logistics to highly automated, AI-supported storage systems, these technologies offer a wide range of options to meet the individual requirements of companies.

Buffer storage: An essential component of fresh and refrigerated logistics

Buffer storage forms the backbone of fresh and refrigerated logistics. They are used to compensate for production surpluses or temporary delays in the supply chain. These warehouses are particularly important to keep the delicate products fresh and ensure that they reach the end customer in perfect condition.

Important aspects of fresh and refrigerated logistics:

• Temperature control: Frozen products such as ice cream or fish require a constant storage temperature between -25 and -28 °C.
• High turnover: Due to the short shelf life of many fresh products, a fast flow of goods is crucial.
• Digital monitoring: Smart sensor systems constantly check temperature, humidity and other storage conditions to minimize quality losses.
• Sustainability: The use of reusable boxes and energy-efficient cooling systems helps reduce waste and emissions.

Buffer warehouses also offer flexibility in picking, which is particularly advantageous during peak times or sudden spikes in demand.

Automatic pallet warehouses: efficiency through automation

Automatic pallet warehouses (APL) are ideal for companies that need to efficiently store large quantities of goods in a small space. These storage systems are characterized by their high storage density and speed, which is achieved through automated storage and retrieval systems.

Advantages of automated pallet warehouses:

• Optimum use of space: Vertical storage means even limited spaces can be used to the maximum.
• Precision and speed: Robot arms and storage and retrieval machines (RSG) move pallets with millimeter precision and at high speed.
• Reduced error rates: Automation minimizes human errors and ensures consistent quality.
• Relief for employees: Heavy, manual work is no longer necessary, which reduces the risk of accidents at work.

By integrating warehouse management systems (LVS), transparency within the warehouse is increased. Companies can access information such as inventory levels, storage space allocation or expiration dates in real time.

High-bay warehouse (HRL): Maximum storage capacity in a limited space

High-bay warehouses are the giants among storage solutions. With a height of up to 45 meters, they offer enormous capacity in a small footprint. These warehouses are particularly suitable for industries that need to store large quantities of standardized products, for example in the food, pharmaceutical or automotive industries.

Features and advantages of high bay warehouses:

• Space efficiency: High-bay warehouses maximize the vertical use of storage space, making them an ideal solution when space is limited.
• Flexibility: They can be designed as built-in storage or free-standing silo storage.
• Technological support: Storage and retrieval machines or shuttle systems transport goods efficiently and safely.
• Integrated software: Warehouse management systems coordinate all processes, from incoming goods inspection to outsourcing.

A high-bay warehouse is not only a logistical necessity, but also a strategic asset that helps companies reduce their storage costs and increase their competitiveness.

AI-driven automated warehouse systems: The future of logistics

Processes are being revolutionized with the integration of artificial intelligence into warehousing. AI-driven systems are not only faster and more efficient, but also able to learn and adapt independently from past data.

Important features of AI-controlled warehouse systems:

Choosing the right storage system

Choosing a specific storage system depends on numerous factors, including storage capacity, product specifications, throughput requirements and available space. From simple buffer storage to automatic pallet storage to highly complex, AI-controlled systems, modern storage solutions offer the right answer for every need. Companies that invest in innovative storage technologies can increase their efficiency, reduce costs and secure their long-term competitiveness.

Modern logistics has developed rapidly over the last few decades and today offers an impressive variety of storage solutions that go far beyond simple shelving systems. From pragmatic buffer storage for demanding fresh produce logistics to highly complex, AI-controlled automatic high-bay warehouses - the selection of storage types is as diverse as the requirements of the most diverse industries. Each type of storage has its specific advantages and disadvantages and is tailored to specific needs.

Buffer storage: The flexible backbone of fresh and refrigerated logistics

In the fast-moving world of fresh and refrigerated logistics, buffer storage plays a central role. They act as temporary buffers that serve to cushion the often unpredictable fluctuations within the supply chain. You can think of it as a kind of “catch basin” that ensures that the flow of goods between production, picking and final shipping runs smoothly and without unnecessary delays. Without buffer storage, the smallest disruptions in the production chain could quickly lead to significant bottlenecks or even the spoilage of sensitive goods.

Special features that make the difference

Fresh logistics places special demands on buffer storage. This is not just about storage, but rather about maintaining the quality and freshness of the products. Cold storage facilities specifically designed for this purpose maintain constant, often very low temperatures. For frozen foods, for example, temperatures of -25 to -28°C are common in order to optimally preserve the products.

Another important feature is the short storage period. Fresh products naturally have a limited shelf life, which is why high turnover rates are essential. Long lying times are an absolute no-go in this area. To ensure this, permanent digital monitoring is essential. This monitoring makes it possible to track inventory levels in real time and ensure that products are processed or shipped as quickly as possible.

The means of transport used also play a role. Reusable boxes are often used in fresh produce logistics. These standardized containers not only make picking easier, but also help reduce packaging waste and optimize loading space utilization.

There are different types of buffer storage. Staging warehouses are used, for example, to prepare goods shortly before further processing or shipping. Consolidation warehouses, on the other hand, are used to consolidate shipments from different sources before they are transported together to their destination. The strategic placement and efficient management of buffer warehouses are crucial for the success of a smooth and cost-efficient fresh logistics chain. Well-organized buffer warehouses are becoming increasingly important, especially in booming e-commerce with its high demands on fast delivery times.

Automatic pallet warehouses: efficiency and space optimization for large quantities of goods

Automatic pallet warehouses provide a state-of-the-art solution for companies that need to store large quantities of goods efficiently. The key to their efficiency lies in the automation of numerous processes.

Features that are convincing

An outstanding feature is the high storage density. By using the room height to the maximum and using narrow aisles, the available space is optimally utilized. This is a decisive advantage, especially in urban areas or where space is limited.

Automated storage and retrieval is usually carried out using storage and retrieval machines (RBG). These robots move along the rack aisles and precisely transport the pallets to or pick them up from their storage locations. This automation leads to a significant reduction in error rates compared to manual storage because sources of human error are minimized. At the same time, throughput times are shortened because the processes run faster and without interruptions.

Another important aspect is the relief of employees. Handling heavy pallets is physically demanding and carries a risk of injury. By automating these activities, employees are freed from these burdens and can be used for more demanding tasks.

There are different types of RBGs used in automated pallet warehouses. Aisle-bound RBGs only move in a single rack aisle, while curved RBGs can also change gears. Modern systems are increasingly integrating shuttle systems that can operate even more flexibly and quickly. Choosing the right system depends on the specific requirements of each warehouse.

High-bay warehouse (HRL): The vertical as an efficiency factor

High-bay warehouses are a particularly impressive form of warehousing. With heights of up to 45 meters and more, they are true “cathedrals of logistics”. They are the ideal solution for companies faced with limited floor space and high storage volumes.

Vertical advantages

The most obvious advantage is the optimal use of the available storage space. Utilizing height maximizes warehouse capacity without requiring additional space.

High-bay warehouses can be designed either as built-in storage or as free-standing silo storage. Built-in warehouses are integrated into existing buildings, while silo warehouses are an independent construction in which the shelves also form the supporting structure of the building. Silo storage offers the advantage of particularly high space utilization and is often the most economical solution for very large storage volumes.

High-bay warehouses also usually use storage and retrieval machines (RBG) or modern shuttle systems to automate the storage and retrieval of goods. These systems are highly precise and operate at high speeds to ensure rapid goods turnover.

The efficiency of a high-bay warehouse depends largely on the integration of warehouse management systems (LVS). These intelligent software systems control and monitor all processes in the warehouse, from goods receipt and storage location management to picking and shipping. The LVS optimizes the storage strategies, minimizes empty trips of the RBGs and ensures an up-to-date inventory overview.

Various storage strategies can be used within high-bay warehouses. With fixed storage, each item has a dedicated storage location. Chaotic storage (also known as dynamic storage), on the other hand, allows for more flexible use of storage space because items are stored wherever there is space. However, this requires a sophisticated transceiver to keep track.

AI-driven automated warehouse systems: The future of logistics

The latest stage of evolution in warehouse logistics is AI-controlled automated storage systems. By integrating artificial intelligence, warehouse processes are raised to a new level of efficiency.

Intelligence for optimized processes

The core of these systems are AI-based algorithms that continuously monitor and optimize warehouse processes. You analyze large amounts of data, recognize patterns and make decisions independently to increase efficiency. This can include, for example, optimal route planning for the RBGs, predicting fluctuations in demand or dynamically adjusting storage strategies.

A key advantage of AI is the automatic adjustment and improvement of processes. The system continuously learns from the collected data and optimizes itself independently. It no longer needs to be programmed or adjusted manually, saving time and resources.

Another important aspect is predictive maintenance. AI algorithms can detect anomalies in the operation of the systems that indicate an impending failure. By identifying potential problems early, maintenance work can be planned and unplanned downtime can be avoided, significantly increasing system performance and redundancy.

AI is used in various areas of warehouse logistics. In inventory management, AI-supported systems help to determine the optimal order quantity and reduce storage costs. In order picking, AI-based robots can take on complex picking tasks and reduce the error rate. AI algorithms are also playing an increasingly important role in route optimization for internal transport or delivery to customers.

The development of AI-controlled warehouse systems is still in its early stages, but the potential for further efficiency improvements and cost reductions is enormous.
