An overall machine operational state (such as a problem state, field state, machine state, other non-problem state, etc.) is identified, and exit and entry conditions are monitored to determine whether the machine transitions into another operational state. When the machine transitions into a problem state, a multiple input, multiple output control system uses a state machine to identify the problem state and a solution is identified. The solution is indicative of machine settings that will return the machine to an acceptable, operational state. Control signals are generated to modify the machine settings based on the identified solution.

A machine subject to state and control input constraints is control, while the control policy is learned from data collected during an operation of the machine. To ensure satisfaction of the constraints, the state of machine is maintained within a constraint admissible invariant set (CAIS) satisfying the constraints and the machine is controlled with corresponding control policy mapping a state of the system within the CAIS to a control input satisfying the control input constraints. The machine is controlled using a constrained policy iteration, in which a constrained policy evaluation updates CAIS and value function and a constrained policy improvement updates control policy that improves the cost function of operation according to the updated CAIS and the corresponding updated value function.

A store is described, including an ordering interface, a storage area, automated vehicles, and a central processing system. The ordering interface accepts selections of items for purchase from a shopper. The storage area, stocking items for sale, is separate from the area containing the ordering interface. The automated vehicles retrieve items from the storage area. The central processing system is configured to: check-in the shopper; assign an order fulfilment module to the shopper; receive selections of items from the ordering interface in real-time, as the shopper selects the items for purchase; send the selections to the order fulfilment module for retrieval in real-time; check-out the shopper when the shopper is finished selecting items; and arrange delivery of the completed order to the shopper. The order fulfilment module assigns automated vehicles to retrieve the items for purchase in real-time. A method for operating a store is also described.
