Why is warehouse design so important?

80% of warehouse Building costs are in the floor slab and roof

In traditional rack storage systems 60% of the space is aisles

>60% of warehouse running costs are related to order picking

Why Automate?Drivers for warehouse automation

• Increasingly high customer service levels

• Difficulty to attract and retain qualified staff

• Scarcity of affordable warehouse space

• Pressure to reduce operational costs

• Increasing health, safety and ergonomics regulations

“Whilst both improved service and lower costs are significant reasons for companies to implement warehouse automation, it is the imperative of the need to accommodate growth that is found to be the main reason.”

Supply Chain Management: An International Journal, 2007, Vol 12(2) pp129-138Authors: Baker, P. & Halim, Z.An exploration of warehouse automation implementations: cost, service and flexibility issues

“In summary, it appears from industry figures that the adoption of warehouse automation is continuing to grow and, from this research, the main reasons are

associated with growth, cost and service.”

Why Automate?

Cross Docking• Cross Docking is a supply chain concept where

the DC does not keep stock.• All cases are distributed to the shops the same

day• Most applied in food, fashion & high tech• Automated cross docking based on sortation

gives many benefits– 50% reduction of manual labour– Triple throughput per m2 in the DC– Store-friendly delivery– 100% correct deliveries are ensured – Supply chain visibility (tracking and

tracing)
