A system for adjusting a representation of a merchandise hierarchy associated with an entity such as a retailer or wholesaler of products. Product correlation information discovered in that entity's customers' shopping records are obtained and incorporated into an existing merchandise hierarchy with a constraint on the consistency with the existing hierarchy.

Merchandise hierarchy refinement by incorporation of product correlation

A data integration module is operable to integrate a plurality of data sources, a customer preference module builds a model representing preference to different channels in merchandise category for each customer segment. A customer satisfaction module creates a model representing customer satisfaction metrics. A joint multi-channel optimization module is operable to use an optimization model that utilizes the customer preference model and the customer satisfaction model and maximize retailer's profit and customer satisfaction.

Maximizing retailer profit and customer satisfaction using multi-channel optimization

A topology structure of a power system is acquired. At least one unification set in the power system is identified based on the topology structure. Devices belonging to the same unification set have the same outage state. The at least one unification set is recorded, so as to concurrently maintain devices belonging to the same unification set. Advantageously, one or more embodiments reduce number of outages caused by power system device maintenance.

Method and apparatus for processing power system topology structure information

A system for detecting conflicts between a power supply guarantee request (PSGR) and an outage request (OR) in a power grid. The system comprises: an accompanying outage analysis device for receiving a first outage device set including OR related devices, and using geographic information about devices in the power grid to determine a second outage device set, the second outage device set including devices in the first outage device set and accompanying outage devices that need to be in outage together with the devices in the first outage device set; an outage scale determination device for using topology information about the power grid to determine a power grid outage scale in which all of the devices in the second outage device set can be in outage; and a conflict detection device for receiving a power supply guarantee device set including PSGR related devices, and judging, for each device in the power supply guarantee device set, whether the device is included in the power grid outage scale.

System for detecting conflicts between outage requests and power supply guarantee requests in a power grid

A method detects conflicts between a power supply guarantee request (PSGR) and an outage request (OR) in a power grid. The method comprises receiving a first outage device set including OR related devices and a power supply guarantee device set including PSGR related devices. Geographic information about devices in the power grid is used to determine a second outage device set, which includes devices in the first outage device set and accompanying outage devices that need to be in outage together with devices in the first outage device set. Power grid topology information is used to determine a power grid outage scale in which all devices in the second outage device set can be in outage. For each device in the power supply guarantee device set, the method detects whether the device is included in the power grid outage scale, to determine any conflict between the PSGR and OR.

A system, method and computer program product for providing the ability for retailers to devise a current channel strategy (e.g., adaptive price setting) that considers competitors in a dynamic competing environment, and that enables computing a competitive advantage of a channel. To estimate a price for selling a product j in a commerce channel comprises: a) receiving, at a processor device, real market data including sales and price history data of a product j sold by one or more retailers over one or alternate sales channels t; generating, by the processor device, a competitive advantage parameter value based on the sales and price history data; and, computing, utilizing the competitive advantage parameter value, an optimum price for a particular product to be marketed in one of the one or alternate sales channel.
