Patent number: 11593739Abstract: Regardless of the production method applied, it is possible for a user to estimate a factor that causes trouble in one of the resources belonging to a resource type. A supporting system refers to management information indicating a production past record of the production system, and displays an overlay chart in which a diagram chart is relatively superimposed on a Gantt chart. The Gantt chart is a chart for a first resource type and has a resource axis and a time axis. The diagram chart is for a second resource type. In the overlay chart, a polygonal line connecting a plurality of points corresponding to a second resource, belonging to the second resource type, is on the Gantt chart, and each point is plotted at a position corresponding to an execution time of a step and a first resource, belonging to the first resource type, related to the step.Type: GrantFiled: July 9, 2019Date of Patent: February 28, 2023Assignee: HITACHI, LTD.Inventors: Kenichirou Kawakami, Shigeyasu Kubo, Kazuhiro Matsuya, Yusuke Yajima

Patent number: 11367032Abstract: As a plurality of resource types relating to production, there are two or more resource types including Money from among resource types of Man, Machine, Material, and Money. Execution past record information indicates, for each of one or more resource types other than Money and for each resource belonging to the resource type, a step performed on the resource and an execution time block of the step. Expense information indicates, for at least one of the above-mentioned one or more resource types and for each resource belonging to the resource type, an expense relating to the resource. The system displays a cost chart based on the result of the cost calculation process. The cost chart shows costs in management unit same as or different from those of the steps, and has a time axis and a management unit axis (axis perpendicular to the time axis).Type: GrantFiled: September 15, 2020Date of Patent: June 21, 2022Assignee: HITACHI, LTD.Inventors: Yoshihito Doi, Kenichirou Kawakami, Megumi Sakai, Yusuke Yajima, Shigeyasu Kubo, Kazuhiro Matsuya

Patent number: 8463302Abstract: In order to narrow down base stations within the tracking-area-based paging area to ones within a smaller area where the mobile unit may exist in a mobile communication system performing the paging on the tracking-area basis, the mobile communication system has a location registration information database memorizing tracking area information, a last location registration information and a N-th (N is an integer of one or more) location registration information from the last for each mobile unit, calculates statistical data on a movement distance for each mobile unit based on the location registration information memorized in the location registration information database, and performs the paging via base stations included both within an area whose radius is equal to the calculated statistical data on the movement distance and within the tracking area.Type: GrantFiled: June 29, 2010Date of Patent: June 11, 2013Assignee: Hitachi, Ltd.Inventors: Shigeyasu Kubo, Yosuke Takahashi, Akihiko Yoshida, Daigo Takayanagi

Patent number: 8185159Abstract: A wireless communication system including a wireless terminal, a plurality of base stations and a call processing control unit is disclosed. The wireless terminal, upon reception of the notification information from any of the base stations, judges whether the area included in the notification information is contained in the location registration area list stored in a storage unit, and in the case where the particular area is not so contained, sends a location registration request to the call processing control unit. On the other hand, the call processing control unit creates a new location registration area list based on the area included in the notification information and the neighboring areas, and sends the location registration area list to the wireless terminal thereby to execute the paging process.Type: GrantFiled: April 1, 2010Date of Patent: May 22, 2012Assignee: Hitachi, Ltd.Inventors: Takashi Itamiya, Shigeyasu Kubo, Akihiko Yoshida, Yosuke Takahashi, Nobuo Ito

Patent number: 8131299Abstract: A call processing control apparatus automatically detects that a lot of handover and location registration simultaneously occur, and notifies a monitor control server. The monitor control server receiving the notification from the call processing control apparatus transmits a TAI change request to a base station so that a tracking area identity (TAI) of a movement destination cell where congestion occurs and a tracking area identity of a movement origin cell have the same value. The base station receiving the TAI change request message from the monitor control server changes its own TAI value. After that, all mobile devices perform only handover when they move between the cells where the TAI values are changed, and does not perform location registration.Type: GrantFiled: November 18, 2010Date of Patent: March 6, 2012Assignee: Hitachi, Ltd.Inventors: Shigeyasu Kubo, Yosuke Takahashi, Akihiko Yoshida, Daigo Takayanagi

Publication number: 20110201330Abstract: A maintenance and administration device of a wireless communication system having for an object to enable the acquisition of accurate location information, even with respect to mobile handsets in the Idle state, sets a mobile handset subscriber identifier and a paging flag to be valid and transmits a visited cell information acquisition request with respect to a call processing control device. In the case where the paging flag is set to be valid, the call processing control device transmits a paging message to the mobile handset, with the mobile handset in the Idle state, and makes it return a reply message. The call processing control device reports, to the maintenance and administration device, the cell having progressively transmitted the paging message reply message as mobile handset visited cell information.Type: ApplicationFiled: January 24, 2011Publication date: August 18, 2011Inventors: Shigeyasu Kubo, Akihiko Yoshida

Publication number: 20100081436Abstract: In a conventional system, there is a possibility that human errors are generated in setting registration information because a maintenance engineer manually enters registration information into a session reference network controller which integrally controls access terminals and base stations. To improve the system, session reference network controller a session reference network controller stores the number of access terminals, N, in advance. And, when a “base distance” setting request is received from an access terminal via a base station, the session reference network controller or an OAM (Operation, Administration and Maintenance) server determines a base station, which is one of a plurality of controlled base stations and is Nth nearest from the base station that has transmitted the setting request, and sets the distance between the base station, which has transmitted the setting request, and the base station, which is Nth nearest, as the “base distance”.Type: ApplicationFiled: June 18, 2009Publication date: April 1, 2010Inventors: Shigeyasu KUBO, Yosuke Takahashi, Akihiko Yoshida, Daigo Takayanagi
