Description
The Shift receives a status change message.
The Shift sends a shift status change message to the Resource Manager.
The Resource Manager changes the status of all resources that use the Shift.
If any resources have transitioned to the idle status, the Resource Manager attempts to service waiting items that depend on those resources.
If items can be serviced, the Resource Manager notifies Queues with wait- ing items that the required resources are available.
The Queues check for being blocked. If they are not, they grant permission to the Resource Manager to allocate the idle resources to their items.
The Resource Manager allocates the resources and changes their status to busy.
The Queues release the items.
