  • Publication number: 20110188404
    Abstract: A method, and system employing the method, for service channel reconfiguration at a service outlet includes generating service transaction data of a service outlet, generating queue management system (QMS) data of the service outlet, and generating cost and profit data for the service outlet. Data is extracted from the service transaction data and the QMS data relating to specified parameters including customer experience data, and customer demand data. The service transaction data and the QMS data is integrated with the cost and profit data providing a unified objective function. Stochastic service processes and customer behavior data are modeled. The unified objective function is evaluated using the stochastic service processes and customer behavior data model, and the service channel function of the service outlet is reconfigured using the unified objective function.

  • Publication number: 20100228858
    Abstract: A method and structure for dynamic allocation of servers to customers in a server farm which supports a flexible contract structure such that the total revenue of the farm is maximized. The invention creates a resource allocation plan based on a long term forecast for the server farm, taking into account traffic, number of servers, customers' contracts and revenue optimization algorithms. The plan is then modified as indicated by short term forecasting using currently monitored load metrics to reallocate to maximize revenue for particular time periods.

  • Publication number: 20090281869
    Abstract: A method and system for integrating multiple factors into a unified optimization model for retail network configuration, in one aspect, obtains input data for modeling store configuration. The input data may include demand of each merchandise category from each customer segment in each facility, geographic distribution of stores in an area, current revenue of stores, and physical cost of reconfiguring stores. A trade area is generated as a function of store location, store format, and store capacity. The method and system also generates trade area demand summation representing predicted total demand of all stores for all merchandise categories for all customer segments in the trade area, as a function of store location, store format, store capacity, merchandise category, and customer segment associated with the trade area. An objective function is constructed as a function of said trade area demand summation, current revenue of stores, and physical cost of reconfiguring stores.

  • Publication number: 20090112954
    Abstract: A method of analyzing a spectrum of one-dimensional or multi-dimensional signal X(t) requires a number of steps including deriving coefficients [AN(?), BN(?)] of an Lp-norm harmonic regression of tie signal with 0<p?? and p?2, squaring the coefficients, summing the squared coefficients, and scaling the summed, squared coefficients with a constant c to realize a periodogram of X(t) as LN(?)=c{[AN(?)]+[BN(?)]2}. The method may include receiving the signal X(t), storing the received signal X(t), and outputting the periodogram LN(?). The method may still further include scanning to maximize the periodogram LN(?) by identifying its largest peak(s) and comparing the amplitude of the identified largest peak(s) with a threshold to determine if the largest peak(s) is(are) attributable to a presence of a periodic signal. The coefficients are preferable derived from a time series signal X(t), t=1, 2, . . . , N, but may include receiving a continuous-time signal and converting it to the time series signal.
