  • Publication number: 20170140403
    Abstract: The present invention aims at providing a technique of helping to quantitatively evaluate a purchasing preference of customers, and design the purchasing preference high in the degree of matching with an actual merchandise purchasing history. The customer analysis system according to the present invention calculates the degree of matching indicative of how much a purchasing preference type of the customer matches a merchandise group in a correspondence relationship on the basis of a merchandise purchasing history of the customer, and evaluates the purchasing preference type on the basis of the calculation result (refer to FIG. 3).

  • Patent number: 9319281
    Abstract: Requested processing time of each batch job is complied with. A resource-correction control server calculating an amount of a resource required for setup of a batch application includes an intermediate-process-unit-data acquiring unit that compiles data of completed batch processes as a single data set at a predetermined time point, a resource-correction determining unit that, using the intermediate process unit, determines a process progress rate that is a progress rate of a process at the current time point and whether the process progress rate has reached a required progress rate that is a progress rate required to terminate the batch process within the requested processing time, and an allocation-resource calculating unit that, as a result of the determination, if the required progress rate has not been reached, calculates the amount of the resource required for recovery of the delay based on a delay-recovery-object progress rate and resource information.

  • Patent number: 7689545
    Abstract: In registering operation of a document to be searched for, a document identifier management table for managing a range of a document identifier stored for each page and a page identifier of the page is created, and an individual-search-server's search range management table for managing the range of the document identifier in charge of each search server is created. In searching operation of each search server of the document to be searched for, the individual-search-server's search range management table is referred to acquire a range of the allocated document identifier. For each index key forming a query term specified as a query condition, the document identifier management table is referred to to acquire the page identifier storing the document identifier of the allocated range. The searching operation is carried out by referring to a page shown by the acquired page identifier.
