  • Publication number: 20200019922
    Abstract: System and method for omni-channel retailer operations that integrate a network of brick-and-mortar stores with their online channel. The system and method includes calibrating a demand model for both brick-and-mortar sales and on-line channels over which a product is sold, the calibrating based upon a cross-channel fulfillment-aware inventory effect. An omni-channel sales prediction and fulfillment model is then constructed based on the calibrated demand model. Using constructed linear demand and revenue models, a plan is generated to optimize one or more: allocating of the product across physical stores, partitioning of the product for sales, and pricing of the product. Customer choices are jointly modeled across channels to allow switching, and a ship-from-store (SFS) inventory effect feature only for brick choice is applied to capture asymmetry.

  • Patent number: 10282795
    Abstract: A streams platform is used. Multiple streams of electricity usage data are received, each from an electrical meter providing periodic updates to electrical usage for devices connected to the electrical meter. Weather information is received corresponding to locations where the electrical meters are. Real-time predictive modeling of electricity demand is performed based on the received multiple streams of electricity usage data and the received weather information, at least by performing: updating a state space model for electrical load curves using the usage data from the streams and the weather, wherein the updating uses current load observations for the multiple streams for a current time period; and creating forecast(s) for the electricity demand. The forecast(s) of the electricity demand are output. Appliance-level predictions may be made and used, and substitution effects and load management functions may be performed.

  • Publication number: 20180005319
    Abstract: Systems, methods, and computer-readable media are disclosed for optimizing terms of a long-term contract between a buyer and a seller for a product. Various types of forecasting models may be generated and used to determine the optimized terms such as an optimized price for the long-term contract. A risk model may be generated and evaluated to identify market disruptions that indicate that the optimized price should be re-negotiated to distribute the associated risk between the buyer and seller. An example of such a market disruption may be a market price fluctuation that causes a difference between a spot market price for the product and a contract price to meet or exceed a threshold value.

  • Patent number: 9626646
    Abstract: Embodiments are directed to a computer implemented method of generating inventory valuation data for an omnichannel (OC) retail operation. The method starts with an unsolvable OC nonlinear nonconvex problem, applies transformations to generate a mixed-integer program (MIP) that is a tractable linear nonconvex form, solves the MIP, fixes prices at optimal values to achieve dimensionality reduction and eliminate all non-convexity by eliminating the pricing dimension. The method further obtains inventory flow linear programming (LP) that is linear convex, and solves the LP to recover a dual solution as initial inventory valuations.

  • Publication number: 20160283882
    Abstract: In one embodiment, a computer-implemented method includes receiving historical transaction data related to a product. A demand model is calibrated to forecast demand for each of one or more zones and each of one or more channels over which the product is sold. A time-and-virtual-space (TVS) network is constructed, by a computer processor, to include one or more supply nodes and one or more sink nodes. Each of the supply nodes represents inventory of the product at a corresponding physical location, and each of the sink nodes represents a calibrated demand for the product. Based on the TVS network, a low-cost plan is determined for an omni-channel retail environment. The low-cost plan specifies at least one of allocation of the product across physical stores, partitioning of the inventory of the product for virtual sales, and pricing of the product.

  • Publication number: 20150317653
    Abstract: Predicting demand of a product offered in multiple channels for a seller that has a plurality of physical store channels and one or more virtual channels, may comprise obtaining transaction log data having records of sales transactions with location identifiers in the one or more virtual channels. The one or more virtual channels may be segmented by locations based on locations of the physical stores and the location identifiers in the transaction log data. A demand model may be estimated by location that incorporates demand for the multiple channels in that location and captures cross-effect of said multiple channels in the same location based on historic sales and transaction data. Integrated price optimization may be performed across all channels and locations that compute one or more prices for each virtual channel and one price for each location in the other channels while also satisfying a plurality of inter-channel and inter-locations constraints.

  • Publication number: 20150235239
    Abstract: Predicting demand of a newly launched product may comprise obtaining customer sentiment data associated with the newly launched product, the customer sentiment data obtained at least from social media. A mean sentiment lag associated with the customer sentiment data may be determined. A weight given to a predicted PLC effect of the newly launched product relative to customer sentiment identified in the customer sentiment data may be determined. Numerical prediction parameters from parameter values associated with a like-item that is determined to be similar to the newly launched product may be obtained. A product utility valuation may be computed as a weighted combination of the predicted PLC effect and a lagged social media sentiment determined from the customer sentiment data accounted by the mean sentiment lag. The product utility valuation provides an indication of the future demand of the newly launched product.
