In logistics, there's a lot of goods movement involved:

• Consolidating loose items into large boxes
• Moving consolidated large boxes to a storage warehouse
• Moving from the storage warehouse to a distribution center
• Consolidating from the distribution center for each store's direction
• Sorting by store from the consolidated directions
• Loading items onto carts for each store

And so on.

In such cases, kanban systems are often utilized, allowing each person in charge to simply transport items to designated locations.

However, factories and distribution centers are generally very large, and it's common for workers, especially temporary ones, to get lost when they don't know where "storage area #35" is, for example, causing them to wander around.

Even if the exact location isn't known, just knowing "it's to your left" or "it's behind you" can significantly reduce time and eliminate considerable waste.

Similarly, this can also be applied to picking and shelving in stores.

Current Costs

Based on the following assumptions, an estimated 9 million yen annually is incurred in costs:

• 5 inexperienced workers per day
• An average of 30 minutes lost per shift
• Labor costs, etc. of 1500 yen per hour
  
• 240 operating days per year
• 10 business sites

Operation Concept

Here's an example using smart glasses:

• A smartphone is kept on standby at all times.
  
• If a worker gets lost, they put on the glasses and say something like "Shelf 35," and an arrow indicates the direction of the shelf.
  
• Once nearby, they visually locate the shelf.

Assumed Operating Environment

• Smartphone
• Smart glasses that display directional arrows, etc.
• Mobile battery
• Cart-mounted stands, etc.
