摘要:
Collectively predicting input operations for plural operation object items (subwindows) belonging to a same window. A proposal window PG stores in a statistics information database and manages information about the input entity and an operation object of an input operation accepted from a user, and a window to which the operation object belongs, along with transition information indicating the transition of active windows concerned in previous input operations. When an active window transitions because of an input operation accepted from the user, it searches the statistics information database for information that contains information about a new active window and is associated with transition information matching the transition of active windows concerned in previous input operations.

Estimation method for obtaining estimation results of meteorological quantities in a specified area during a specified future period, including steps of: provisionally creating a meteorological time-series model from historical data of the meteorological quantities observed in the specified area; adjusting parameters of the created time-series model on the basis of long-range weather forecast data for wider area, which contains future meteorological tendency relative to normal years, to adjust the created time-series model; and conducting simulation using the adjusted time-series model to obtain the estimation results.

An IT system is operated reflecting a management policy accurately. In a method for determining allocation of IT resources of an IT system shared by divisional operations of an organization based on management resources allocation among divisions in the organization, the method comprises a first and a second steps of resource allocation. In the first step, management resource allocation for each of the divisional operations is determined so as to optimize a value of an operational objective based on the assumption that IT resource allocation is equal among the divisional operations and based on the management resource allocation among the divisions of the organization. In the second step, IT resource allocation for each of the divisional operations is determined so as to optimize the operational objective value based on the management resource allocation for each of the divisional operations determined in the first step.

The amount of risk in weather derivatives is calculated properly by taking into account a correlation between weather observation sites and a correlation between meteorological elements. A weather prediction method by creating a weather scenario from historical weather data includes a first step of estimating parameters of a weather time-series model based on historical weather data including past plural meteorological elements, a meteorological element correlation between sites, and a correlation between meteorological elements, and a second step of converting random numbers into meteorological elements based on the estimated parameters. The second step is executed a given number of times to create a plurality of weather scenarios.

Provided is a method of measuring the effect of investment in an IT system by calculating the correlation between data on profit derived from an IT system. Various time-series data collected from a business system are classified into a profit indicator (104), a business process progress status indicator (105), and a system operation status indicator (106), and the correlation between those data is found. From the correlation, a contribution ratio indicative of the influence of the IT system operation status on the profit is calculated, and the effect of investment in the IT system is measured based on this contribution ratio.

When a parameter for a numerical computation library is required, an optimum parameter reflecting a user policy is provided. A program calculates, based on a preset objective function, an optimum tuning parameter for executing a numerical computation library. The program reads the numerical computation library; reads the objective function; sets a user policy regarding speed performance and computational accuracy of the numerical computation library as plural policy parameters; reads, from preset execution histories of numerical computation libraries, execution histories of the numerical computation library; calculates, in a domain where the policy parameters are met and based on the execution histories having been read in, a tuning parameter for the numerical computation library by using the objective function; and outputs a calculation result of the objective function.

A symptom state shifting from a low load state to a high load state is detected. A measured value collection unit 131 stores measured values of a queue length measured by a queue length measurement unit 31 of each server 3, into a measured value storage unit 14. A fluctuation calculation unit 132 calculates a fluctuation of measured values that have been measured in a given time for each server. A symptom state judgment unit 133 compares the calculated fluctuation with a threshold to judge whether the server 3 for which the fluctuation has been calculated is in the symptom state or the high load state.
