At the textile plant of FEPV, products and raw materials are stored in and retrieved from the warehouse with manual operation and forklifts. Such operation is time and labor intensive. In 2021, the plant installed an automated warehouse system with sorting loop vehicle (SLV), which automatically delivers the raw materials into the warehouse, and from the warehouse to the unit with material requisition. At the end of the production process, SLV may also deliver the finished fabric products to the warehouse. With the previous manual warehouse operation, 40 metric tons of raw materials would require 6 hours to complete, but it takes only 4 hours with SLV. SLV routes can be programmed through smart systems, which drastically enhance energy and operational efficiency.
