Case Study
High Rate Crossdocking at Variable Speeds
The Challenge JCPenney had two criteria for the Lathrop DC,” says Mike Harding with Dematic. “One, high throughput, capable of handling at least 150,000 – 200,000 cartons per day over two shifts; and two, it had to be built fast, within six months. Dematic was brought in to design and build out the entire material handling facility. Our Solution It was on this project that Dematic introduced JCPenney to its new high-rate sortation technology called Integrated Sortation System, or ISS for short. The philosophy behind ISS is to treat the entire sortation system – composed of separate components like the pre-merge, merge, gapping and sortation – as one machine fully integrated from a single point of control. The ISS system is constantly adjusting speeds based on: (a) how m
