Abstract: The invention relates to a group-control elevator system for controlling an operation of elevators a group by control data. The group-control elevator system stores a plurality of improvement measures corresponding to plural inconvenience phenomenon including a long average wait time for the plurality of elevators. The inconvenience phenomenon is detected from actual data of the elevators, and the actual data is obtained by actual elevator operation and one improvement measure is selected from the improvement measures in accordance with the detected inconvenience phenomenon.

Abstract: In a group-management control apparatus for an elevator system with plural elevators capable of serving plural floors, hall calls are allotted to adaptive elevators in accordance with a predetermined hall call allotment algorithm, for the purpose of achieving desired control targets. Plural kinds of the hall call allotment algorithm with different schemes are provided in advance, and the predetermined hall call allotment algorithm is selected therefrom by a reasoning operation, which is executed in accordance with a reasoning rule selected from among a plurality of reasoning rules empirically provided in advance on the basis of the desired control targets and an operating state of the elevators.

Abstract: A control system for an elevator has a plurality of elevator information generation devices each of which has an information output unit which outputs elevator information to an elevator controller and also to at least one display controller which generates one or more on elevator displays. There are a plurality of display controllers, these are preferably connected to the information output units by a common transmission path. There may be a plurality of elevator controllers, when there are a plurality of elevator cabs, and those elevator controllers may all be connected to the common transmission path. There is then a supervisor controller for controlling the elevator controllers.

Abstract: A customer participatory elevator control system includes a device for setting and storing information necessary to operate a plurality of elevators on trial and a device for operating the elevators on the basis of the trial operation information. When the customer inputs into the control system a request which is unexpected to the elevator maker in the course of design of operation specifications, the control system enables the customer to carry out a trial of elevator call assignment control and guide control in accordance with the customer's request and changes the designed elevator operation specifications in accordance with results of the trial.

Abstract: The present invention relates to a display guide apparatus of elevator facilitating alteration of display format and to its display method. A display guide apparatus according to the present invention comprises an elevator control unit, an information producing unit, and an information display control unit. The information display control unit is so configured that an auxiliary memory medium, which has stored therein information required for displaying the running information of the elevator, may be mounted thereon. At least information required for displaying the running information of the elevator is supplied from the auxiliary memory medium. Information required for displaying general information is supplied from the information producing unit. On the basis of information relating to the running situation of the elevator supplied from the elevator contorl unit, the running information of the elevator and the general information are displayed by display units disposed at least at halls to perform guidance.

Abstract: An elevator control system comprises an elevator controller for controlling the running of a cage and a plurality of input/output terminal equipments for controlling devices provided at a landing place on each floor and/or in the cage, each of the elevator controller and the plurality of input/output terminal equipments including a transmission controller provided with a transmission circuit and a reception circuit so that the elevator controller and the plurality of input/output terminal equipments are connected to each other through transmission lines, wherein each of the elevator controller and the plurality of input/output terminal equipments is provided with an abnormality detector for detecting an abnormality and a transmission stopping device for inhibiting transmission through the transmission circuit of its own transmission controller upon detection of occurrence of an abnormality by the abnormality detector.

Abstract: In a group-control for an elevator system with plural elevator cages, when a hall call is generated, evaluation values of all of group-controlled cages with respect to the generated hall call are calculated by a predetermined evaluation function, as expressed by the following formula:.phi..sub.n =(WT-k.sub.p Z.sub.p +k.sub.c T.sub.c +k.sub.L L.sub.L -K.sub.z Z.sub.Z -k.sub.s Z.sub.s).sub.nn=1, 2, . . ., Nwherein N denotes the total number of group-controlled elevator cages, WT, Z.sub.p, T.sub.c, L.sub.L, and Z.sub.s represent evaluation indexes of a waiting time, an equal time-interval operation preferential zone, a riding time, a cage-load factor, a first-arriving cage preferential zone and a stop call, and k.sub.p, k.sub.c, k.sub.L, k.sub.z and k.sub.s represent control parameters for the last five of the evaluation indexes above, respectively. The generated hall call is allotted to a cage having a minimal evaluation value calculated by the aforesaid evaluation function.
