By using, as input, elevator specification information including at least sizes, quantity, and service floors of a plurality of elevators, a method for installing the plurality of elevators is calculated based on either the quantity of the plurality of elevators or the sizes of the plurality of elevators from arrangements including at least one or more of a planar arrangement where the plurality of elevators are aligned in a row on one side configuring an elevator boarding place, or an opposed arrangement where the elevators are divided and located on two opposite sides configuring the elevator boarding place; the shape of the elevator boarding place is determined by calculating the two sides configuring the elevator boarding place on the basis of the installation method and the sizes and quantity of the plurality of elevators; and furthermore, an elevator boarding place layout is generated by determining each floor where the elevator boarding place is to be installed according to the service floors.

In-building traffic prediction system and elevator boarding place layout generation method and non-transitory computer-readable recording medium for storing program for in-building traffic prediction system

An OD matrix estimation device includes: an extraction unit that, on the basis of intra-bank OD matrixes that show traffic flow information in respective elevator banks in plural elevator banks and transfer floor information about a transfer floor where transfers among the elevator banks is possible, extracts transfer-related intra-bank OD matrixes having a common transfer floor from among the intra-bank OD matrixes; a matching unit that, from among the transfer-related intra-bank OD matrixes extracted by the extraction unit, combines first transfer intra-bank OD matrixes each including OD data in which the transfer floor is defined as an arrival floor with second transfer intra-bank OD matrixes each including OD data in which the transfer floor is defined as a departure floor to create transfer-related OD data; and an estimation unit that estimates OD data for users who transfer and move among the banks.

Method for estimating intra-building traffic, and system for estimating intra-building traffic

In a building human flow estimation system having a building human flow simulation section which receives, as input values, building traffic data indicative of floors between which people move by using an elevator in a building, building layout data related to a layout of the building, and an elevator parameter value related to the elevator and estimates a flow of people, there are provided an evaluation section which calculates an evaluation value for evaluating a reproduction degree of the flow of people estimated by the building human flow simulation section based on a first evaluation index related to the flow of people estimated by the building human flow simulation section and a second evaluation index related to an actual flow of people in the building, and an output section which outputs the evaluation value calculated by the evaluation section.

Building human flow estimation system and estimation method

To make it possible to comprehensively predict the movement of people by associating an elevator control system in a facility such as a building and an external system other than this system with each other and thereby provide a new service that has not existed before. There is provided an elevator operation management system for controlling and managing multiple elevator devices in a facility, the system including: a reception unit that acquires information on the number of users to use the elevator devices and elevator car destination information; a learning unit that stores and learns, as past experience data, the information on the number of users and the elevator car destination information acquired from the reception unit; a per-floor number-of-people estimation unit that estimates the number of users getting off at each elevator hall floor using storage information of the learning unit; and a request information output unit that outputs the number of people getting off thus estimated in the facility to a system other than the elevator operation management system.

Elevator operation management system and elevator operation management method

An elevator group control system for controlling multiple elevators cars each of which serves a plurality of floors includes a route preparation section which, at a time of assigning a hall call to one of the elevator cars, calculates a future trajectory for each of the elevator cars. The future trajectory for each elevator is for a case in which the hall call is assigned to the elevator car. A selecting unit which determines a selected one of the elevator cars to which the hall call is to be assigned using the calculated future trajectories.

Elevator group supervisory control system with route preparation section

An elevator group control system includes a reference route generating portion, which for each elevator, generates a reference route which the elevator should follow with respect to the time axis and position axis; and an assignment portion which selects an elevator for assignment to a generated hall call so as to make the actual trajectory of each elevator closer to its reference route. Reference routes which guide the cage's trajectory into temporally equal interval condition are generated, and car assignment is executed to allow the cages to settle in temporally equal interval condition over a long period of time.

Elevator group supervisory control system using target route preparation

A method and a display for elevator allocation evaluating are provided. When an elevator allocated to a hall call is selected by employing two different view points such as a real and a future call evaluation index, an elevator allocation reason and a balance between the two view points can be easily grasped. An elevator allocated to a hall call is evaluated on orthogonal coordinates in which the real call evaluation index and the future call evaluation index are defined as an X and a Y coordinate axis. Evaluation indexes of first to fourth elevator cars are evaluated by employing contour lines of a synthetic evaluation function, which is represented as the real and the future call evaluation index. A weight for allocating is displayed visually.

Method, system, and display for elevator allocation using multi-dimensional coordinates

An elevator group control system is provided which stably keeps cage's position in temporally equal interval condition over a long period of time. The present invention provides a system comprising: reference route generating means, which for each elevator, generates a reference route which the elevator should follow with respect to the time axis and position axis; and assignment means which selects an elevator for assignment to a generated hall call so as to make the actual trajectory of each elevator closer to its reference route. Since reference routes which guides the cage's trajectory into temporally equal interval condition are generated and car assignment is executed so as to make the respective cages follow their reference routes, it is possible to allow the cages to settle in temporally equal interval condition over a long period of time.
