1. Problem description:
optimize the target
- It is required that the higher the outbound frequency of the goods, the shorter the outbound time, that is, the cargo location is arranged closer to the outbound platform. For the goods with lower inbound and outbound frequency, the inbound and outbound time can be relatively long .
- The distributed storage of materials avoids the problem of uneven force of the cargo compartment caused by centralized storage. The heavy objects are on the bottom and the light objects are on the top, making the shelf more stable (minimum center of gravity).
- Targeted at the principle of relevance of classified goods, and the same kind of goods that are put into the warehouse first have priority when they are out of the warehouse.
The optimization objective function is constructed as follows:
