Abstract: The present invention proposes an information processing apparatus and an information processing method which are capable of efficiently acquiring site data by selecting an optimum data model from a plurality of data models according to a factory site. A processor receives site identifying information for identifying a site from an input/output unit, calculates a first cost which is a cost of the site identified by the site identifying information based on site information of the site identified by the site identifying information, selects a specific data model corresponding to a site having a second cost similar to the first cost from among the plurality of data models based on the first cost and related information, and outputs the selected specific data model to the input/output unit.

Abstract: A production system between processes is automatically determined using work performance data acquired at a production site, and a process model in which a flow shop and a job shop are mixed is automatically generated. A process model automatic generation system 210 reads work performance data from work performance data 120 and extracts a process flow for each product (130). Next, a synthesis flow obtained by combining a plurality of process flows is created, and a production system between processes corresponding to a closed path is changed to a job shop to automatically determine a production system (140). Finally, a process model in which a flow shop and a job shop are mixed is generated (150) and displayed on a display screen 160.

Abstract: To provide a technique for supporting generation of a process model suitable for a task generated on a site. A process model creation system creates a model used for managing, in a process including a plurality of tasks, site data acquired on a site of each task, and defining a flow of the tasks in the process. The process model creation system includes: a model accumulation unit configured to accumulate the model; a difference data creation unit configured to create, based on the site data acquired on the site, an instance indicating a flow of actually executed tasks, and extract differences between the instance and the model as difference data; and a model modification unit configured to create a modification proposal of the model based on the difference data.

Abstract: When a carrier aggregation using a macro cell of a legacy carrier as a primary cell and using a small cell of a new carrier type as a secondary cell is performed, transmission of a control channel (PUCCH) of an uplink is concentrated on an uplink of the macro cell and frequency efficiency is degraded. For this reason, in a state in which the macro cell is configured as the primary cell, a serving cell transmitting the PUCCH is configured to a terminal and the terminal transmits the PUCCH using the configured serving cell.

Abstract: Even when a downlink radio traffic volume is larger than an uplink radio traffic volume in a radio communication system, but uplink resources are redundant in a related art radio communication system, free uplink resources could not be sufficiently utilized. In a base station having a cellular unit that performs cellular communication with a terminal, and a D2D unit that performs communication with the terminal through a device-to-device communication system, when the downlink radio resources get tight, and the uplink radio resources are redundant, the D2D unit of the base station conducts transmission and reception with the terminal with the use of the uplink radio resources.

Abstract: In an environment in which a macro base station and a low transmission power base station exist, the ratio of the interference reduction time period of the macro base station is optimized, and the throughput of the low transmission power base station is improved, while minimizing a reduction in throughput. The macro base station causes a high interference to other base stations and one or a plurality of low power nodes (LPN) subjected to interference from the macro base station. The macro base station sets first and second data transmission time periods and then determines the ratio of the second time period and the pattern of the first time period and the second time period based on communication quality in the first time period and communication quality in the second time period of the macro base station and the LPN.
