Business Model

Generally, e-commerce platforms provide exchange deals on smartphones to the users. They pick up the used phones from the users while providing the new one the user bought from them.

Those used mobiles are now sent to third-party retailers and now need to be stocked up in warehouses.

These mobiles are now supposed to become inventory in warehouses and available for sale to liquidators.

Problem Statements

1. Before the phone has arrived at the warehouse, only the original SKU of the phone (iPhoneX) that is about to arrive is known.
2. The problem is to assign a SKU depending upon its working functionality and quality.
3. To do this, it has to go thorough quality check and grading and then assignment of quality grade to the phone should happen.
