At least one microservice component is configured to be tightly designed, stateless and loosely coupled with said WEX and MAS. The VTS is the at least one microservice component.
A method and system for opportunistically picking order items during decant processes. An order management system determines which items required for a pending order are depleted within a decant function or storage system and orders replenishment, such as inbound vendor cases containing the depleted required items, to the decant function. Operators at decant workstations pick the required items from the inbound vendor cases into order containers while simultaneously decanting any remaining, non-required vendor items into inventory containers. The order containers and the inventory items are stored in a storage system until all required items for an order are present therein. Once all required items are present, the items are released to a downstream picking workstation, sorter, and/or packing station. The method with opportunistic decant may enable minimized facility space requirements, labor reductions, and resource reductions while improving facility throughput.

The storage buffer holds customer orders until the customer arrives to retrieve them and may store portions of orders at different temperatures. The dispensing system includes a confirmation sensor system to verify whether a customer has retrieved their entire order or whether the customer has rejected one or more of the order items. The dispensing system provides the order to the customer within about two minutes of the customer indicating that they are at the access portal and ready for their order.
Methods and systems are provided for verifying a pick/put operation within an order fulfilment workstation or a storage rack.

The control system determines a relative location of the indicia and then determines the location at which an item was picked from or put to relative to the workstation within a high degree of positional accuracy. The method verifies that the operator has completed the assigned pick/put operation at the required location. The methods and systems may be adapted to track or monitor relative positions of mobile and stationary equipment in an automated warehouse.
