ReShare uses a load balancing process to determine the order of suppliers in the rota for a given request. At this time, the load balancing process is only used with ReShare’s Shared Inventory integration, but it may be extended to other shared index integrations in the future.

...

For more information about working with load balancing for a specific ReShare tenant, seeLoad balancing configuration.

Load balancing algorithm

ReShare uses a ratio-based approach to load balancing. This approach allows each library to define its goal loan to borrow ratio. When libraries are considered as suppliers, ReShare assigns a load balancing score by comparing the library’s goal ratio to its current breakdown of loans.

...

A negative load balancing score indicates that the library has already loaned more than its target, so it will be assigned a lower place in the rota.

Load balancing examples

Example 1: In this example, the library has not lent as many items as it might, based on the goal ratio. It receives a load balancing score of 4 – in other words, it needs to lend 4 more items to reach the target ratio.

...

Example 2: In this example, the library has has lent more items than required according to its goal ratio. It receives a load balancing score of -12, meaning that it is 12 loans ahead of the target ratio. It would be ranked below the supplier with a positive score in the example above.

Configuring goal loan-to-borrow ratio

Each library can define its own loan-to-borrow ratio using the Directory app. By default, the goal ratio will be 1:1 unless changed.

To change the loan-to-borrow ratio:

...

Navigate to the Directory app.

...

Open your library’s institution-level directory entry. This will be the entry with a type of “Institution.”

...

Choose Actions>Edit.

...

Open the Custom properties accordion and scroll to the bottom of the page to view the “ILL loan to borrow ratio” field.

...

Enter a loan to borrow ratio in the format: x:x.
