Abstract: Proposed are a standard time estimation device and a standard time estimation method capable of estimating the standard time accurately and quickly, which in turn can speed up and facilitate the planning work of a production plan. With this device and method, attributes of a product are grouped into a group that carries a meaning by the attributes being combined, and all combinations of values of each of the attributes configuring the group are extracted as a pattern from a past manufacture track record, for each of the patterns, a representative value of a real operating time is respectively calculated based on the past manufacture track record, a standard time is learned based on the representative value for each of the calculated patterns, and the standard time of the product is learned based on a learning result.

Abstract: A production management supporting system analyzes past record information including information showing, for each product loaded in a production line in which a plurality of steps are performed, an execution time of each of the steps on the basis of one or more attentional perspectives to detect, from among objects displayed on a diagram chart showing a production situation, display objects each satisfying one or more requirements associated with the one or more attentional perspectives. The production management supporting system performs accentuated display of at least one of the detected display objects.

Abstract: A production management supporting system specifies, for each of one or more times during a display target period and on a per inter-step and/or intra-step range basis, a retention number as the number of products present at the time on the basis of past record information, for each product loaded in a production line, an execution time of each of the steps and that serves as a basis for a diagram chart showing a production situation. The system determines whether or not one or more retention situations satisfies a predetermined requirement and performs, when there is the satisfying retention situation, accentuated display of a target portion that is a portion, of the diagram chart, which corresponds to an inter-step range and/or an intra-step range in which the satisfying retention situation has occurred and to a period having the satisfying retention situation.

Abstract: In a case where a switching source wireless communication system is a wireless communication system in which a transmission timing of a packet or data rate can be controlled in a wireless base station, the switching source wireless communication system, which notifies information on a timing when a wireless terminal communicates the switching destination wireless communication system with respect to the switching source wireless communication system in advance, starts time-division communication between switching destination and switching source wireless communication systems, and receives the timing information, controls a transmission timing or a data rate in accordance with the timing information.

Abstract: A call connection request from an access terminal is suppressed in a state in which the base station judges that the call connection is impossible, thereby suppressing a waste of the wireless band and the generation of noise. A BCMCS management block of an access point receives information indicating whether there is an allocable channel, from a channel management block of the access point, and information indicating whether the start of QoS can be accepted, from a QoS acceptance determination block of the access point, and the BCMCS management block distributes the information to the access terminal. Accordingly, the access point can inform the access terminal that it is not serviceable before channel allocation is attempted.

Abstract: If a wireless resource congestion occurs, the wireless resources of the entire system are used efficiently to reduce a disconnection of communication with a congested sector and a state in which a new call cannot be originated nor terminated. A base station control apparatus compares the wireless resource usage amount of each sector of each base station with values stored in a wireless resource threshold table. If a sector of a base station is in the light congestion state, the neighbor search window size of a sector specifying the congested sector as a neighbor is changed to restrict a soft hand-over to the congested sector. If a sector of a base station is in the heavy congestion state, a mobile station which is communicating in the congested sector and receiving radio waves of another sector with stability is subjected to a forced soft hand-over.
