4flow, a provider of logistics consulting, logistics software and logistics management, has published the results of its new study on warehouse automation and volatile demand. In the study "Warehouse automation and volatile demand - a strategic fit?", 4flow answers key questions in the field of warehouse planning for supply chain decision-makers: Under what conditions is the automation of a warehouse profitable? Can the service level requirements be met in view of possible flexibility restrictions of automated warehouse technologies?

Striking a balance between free capacity and maximum warehouse efficiency is an ongoing challenge for supply chain management and logistics. A warehouse that is too large is not cost-efficient - at the same time, opting for a design that is too compact can lead to significant losses in service levels, for example due to stock shortages. The efficiency of a warehouse depends not only on its size but also on the degree of automation. High costs for automation technology also make it difficult to decide on the optimal size of the warehouse. Companies also need flexibility in their operational processes - a requirement that automation technology cannot always meet. "Ultimately, the business case for automation depends on good planning and forecasting future requirements as accurately as possible," explains Wendelin Gross, Head of Research at 4flow. "The study highlights the key factors that need to be considered to make a more informed decision about warehouse automation."

To this end, the study compared a manual warehouse concept with forklift trucks and shelving racks with an automated warehouse solution that combines automated guided vehicles (AGVs) and a high-bay warehouse with storage and retrieval machines. The objective was to analyze the cost and performance indicators, the service level and the payback period for the automation solution.

The 4flow team analyzed various cost and performance drivers in detail and came to the conclusion that different demand volatility and costs caused by out-of-stocks in the case study under consideration lead to a payback period of between two and six years for the automated solution.

Based on the findings of the study, 4flow provides specific recommendations for companies considering automating their warehouse. This includes paying close attention to demand volatility, taking into account the development of location-specific factors such as rent and labor costs, and applying a standardized planning approach with 3D layout planning and a sensitivity analysis that considers all important cost and performance-related factors.

Interested users can explore selected results of the study themselves in an interactive web-based model. A large number of adjustable parameters make it possible to generate different scenarios and assess whether an investment makes sense based on the cost and performance figures.
