Issue background

  • The company has difficulty increasing the number of operators, and so aims to increase operator productivity and reduce shipping mistakes.
  • In light of the time it takes to respond to complaints about shipping mistakes, the company wants to prevent operators from inserting items into the wrong openings.
  • The company does not want to use separate racks for drink crates and milk crates; they want to use the same racks for both.
  • The company wants to use the racks wherever they are needed in the warehouse due to volume and timing. They also want to store the racks in a different place when they are not being used.

  2. Affixing a different color of LED tape to each row prevents operators from inserting items into the wrong row.
