Patent number: 8341012Abstract: A working skill estimating program is provided for estimating working skills of each agent in the state of separating a disturbance factor from response records (incidents). A large category classifier is supplied with the incidents within a predetermined time and classifies the incidents according to classification rules, for creating the topic-classified incidents. A small category generator collects the analogous incidents for each task type of the topic-classified incidents and generates a small category. A disturbance distinguisher distinguishes if the incidents belonging to each small category are common response records that appear regularly over time or disturbances whose frequency exhibits a significant time dependency. Then, a skill estimator estimates the working skills of each agent for each task type by using only common incidents determined as the common information.Type: GrantFiled: July 27, 2005Date of Patent: December 25, 2012Assignee: Fujitsu LimitedInventors: Hideki Yamanaka, Takashi Yanase, Isao Namba

Publication number: 20100082948Abstract: In a CCW fetching section, for each input/output device being a control objective, a result prediction table in which prediction values of status values to be returned from an input/output device as execution results of CCW commands, is referred to. Then, based on the prediction values, commands being pre-fetching objectives are pre-fetched from a CCW program stored in a memory, and transmitted to a CCW executing section. On the other hand, in the CCW executing section, the pre-fetched commands are sequentially executed, and the actual status values as the execution results are received from the input/output device. Then, when the received actual status values are not same as the predicted status values, success or failure in prediction is notified to the CCW fetching section, and also, the result prediction table is updated in the CCW fetching section.Type: ApplicationFiled: June 29, 2009Publication date: April 1, 2010Applicant: FUJITSU LIMITEDInventors: Tsukasa Matsuda, Hideki Yamanaka
