Abstract: A simulator is configured to simulate the fulfillment of orders by nodes. Each node has an inventory of products and is capable of shipping the products to destinations in response to receipt of a corresponding order. The simulator divides the nodes into groups and assigns a different priority to each group based on input provided by a user to the simulator to generate an ordered sequence of priorities. The simulator maintains safety stock data corresponding to each node that indicates minimum quantities of the products required to be present at the corresponding node. The simulator selects a current priority of the sequence and next simulates a first group among the groups having the current priority fulfilling the orders for a given product among the products while a quantity of the given product at each of the nodes in the first group is below the minimum quantity in the corresponding safety stock data.

Abstract: In some embodiments, methods and systems of managing overstock products at a retail sales facility include scanning a product at a stock room location of the retail sales facility using a hand-held electronic device including a processor. At least two of three functions are performed based on the scanning. First, the product may be audited by comparing data obtained by scanning the product to data contained in an inventory management database. Second, a determination of whether the scanned item is on a pick list may be made, which may include determining a demand for the scanned product to arrive at a decision whether to store the product in the stock room or place it on a shelf on the sales floor. Third, if the item is to be stored in the stock room, a determination of whether identical items are stored in bins in the stock room may be made.

Abstract: Performing a financial transaction via a mobile device and a point-of-sale (POS) system may include utilizing the POS system to generate a digital code, communicating the digital code from the POS system to the mobile device, connecting the mobile device to a wireless network using the digital code as a password, forwarding a mobile identifying code, forwarding a network identifying code, transmitting transaction data associated with information regarding the financial transaction, the digital code, the mobile identifying code, the network identifying code, and account information associated with the POS system from the POS system to a payment system via a first digital network path, and transmitting the digital code, the mobile identifying code, the network identifying code, and account information associated with a user of the mobile device from the mobile device to the payment system via a second digital network path.
