TEMPERATURE-DRIVEN DYNAMIC ORDER SEQUENCING IN ORDER FULFILLMENT
Systems and methods for temperature driven dynamic order sequencing in order fulfillment are provided herein. In some embodiments, a method of controlling two or more actively cooled totes includes: determining a first ordering of the two or more actively cooled totes; determining that an alert condition occurred for an alerted tote of the two or more actively cooled totes; and determining a second ordering of the two or more actively cooled totes based on the alert condition where the alerted tote is in a different position in the ordering than in the first ordering. Dynamic tote arrangement can therefore ensure that customer orders are sequences appropriately based on the temperature warnings the totes provide, minimizing spoilage in the tote queue process.
1 . A method of controlling two or more actively cooled totes, the method comprising:
determining a first ordering of the two or more actively cooled totes;
determining that an alert condition occurred for an alerted tote of the two or more actively cooled totes; and
determining a second ordering of the two or more actively cooled totes based on the alert condition where the alerted tote is in a different position in the ordering than in the first ordering.
2 . The method of claim 1 wherein the two or more actively cooled totes are controlled by one or more automated guided vehicles.
3 . The method of claim 1 wherein one or both of the first ordering and second ordering are determined by a Warehouse Execution Software.
4 . The method of claim 1 wherein determining that the alert condition occurred for the alerted tote comprises receiving a warning from the alerted tote.
5 . The method of claim 4 wherein the warning from the alerted tote indicates the alerted tote is getting close to its threshold temperature for product safety or integrity.
6 . The method of claim 1 wherein determining the second ordering comprises one or more of:
deprioritizing the alerted tote and/or sending the alerted tote back to a rack position or other charging location;
sending the alerted tote to an order buffer charging rack;
moving the alerted tote to the front of the line to be the next order processed; and
moving the alerted tote at least early enough to avoid negative repercussions for the product in the alerted tote.
7 . The method of claim 1 wherein one or more totes preceding the alerted tote are moved out of the way.
8 . The method of claim 1 wherein determining that an alert condition occurred for an alerted tote comprises determining that an amount of battery left for the alerted tote is insufficient for the amount of time needed to schedule the alerted tote.
9 . A system for controlling two or more actively cooled totes, the system comprising processing circuitry configured to:
determine a first ordering of the two or more actively cooled totes;
determine that an alert condition occurred for an alerted tote of the two or more actively cooled totes; and
determine a second ordering of the two or more actively cooled totes based on the alert condition where the alerted tote is in a different position in the ordering than in the first ordering.
10 . The system of claim 9 wherein the two or more actively cooled totes are controlled by one or more automated guided vehicles.
11 . The system of claim 9 wherein one or both of the first ordering and second ordering are determined by a Warehouse Execution Software.
12 . The system of claim 9 wherein determining that the alert condition occurred for the alerted tote comprises being configured to: receive a warning from the alerted tote.
13 . The system of claim 12 wherein the warning from the alerted tote indicates the alerted tote is getting close to its threshold temperature for product safety or integrity.
14 . The system of claim 9 wherein determining the second ordering comprises being configured to perform one or more of:
deprioritize the alerted tote and/or sending the alerted tote back to a rack position or other charging location;
send the alerted tote to an order buffer charging rack;
move the alerted tote to the front of the line to be the next order processed; and
move the alerted tote at least early enough to avoid negative repercussions for the product in the alerted tote.
15 . The system of claim 9 wherein one or more totes preceding the alerted tote are moved out of the way.
16 . The system of claim 9 wherein determining that an alert condition occurred for an alerted tote comprises being configured to: determine that an amount of battery left for the alerted tote is insufficient for the amount of time needed to schedule the alerted tote.
