Description

The invention relates to a method for allocating calls of an elevator installation as well as an elevator installation with an allocation of calls according to this method according to the preamble of patent claim 1.

A method according to the preamble of claim 1 is, for example WO-A-9737922 known.

An elevator system with a group of elevators and a group control with instant allocation of calls in the form of destination calls, for example, from the Scriptures EP0356731A1 known. Thus, a passenger on a landing floor enters a destination call for a destination floor and receives from the group control an instant allocation of an elevator. The passenger climbs the cabin of the elevator and is moved from the input floor to the destination floor without the need to enter another cabin call in the cabin.

The destination floor is communicated to the group control early on by a destination call already on the input floor, and not only with the car call in the cabin. This allows the group control an allocation of elevators for the shortest possible waiting time and / or travel time of the individual passenger. In addition, with the same number of elevators, the capacity of the elevator system is increased.

The object of the present invention is to further increase the delivery rate of an elevator installation.

This object is solved by the invention according to the definition of the preamble of the independent claim.

The invention relates to a method for allocating calls of an elevator installation with at least one elevator and at least one cabin per elevator. At least one passenger enters at least one call on a destination floor. A plurality of passengers is moved according to input calls from the cabin in at least one drive from at least one input floor to at least one destination floor. For the entered calls of the journey, at least one start zone with one or more input floors is determined. For the entered calls of the journey, at least one destination zone with one or more destination storeys is determined. If at least a number of stops in the starting zone and / or in the target zone is greater than one, this number of stops is reduced.

The advantage of the invention is that not the waiting time and / or travel time of the individual passenger is optimized operation costs, but that the waiting time and / or travel time of the entire cabin is optimized operation costs. This is done by determining a start zone and / or a target zone and reducing the number of stops in the start zone and / or in the target zone. In contrast to the prior art, where each passenger is compelled to travel from his input floor to the destination floor indicated by him, there is thus a movement of the passengers from a start zone to a destination zone, where not every entry floor and / or destination floor is held. As a result, the capacity of the elevator system is further increased.

Advantageously, the start zone is formed by the entirety of the input floors. Advantageously, the target zone is formed by the totality of the destination floors.

This has the advantage that for each trip of the cabin, virtual zones can be formed, which can be specifically optimized.

For this purpose, at least one stopping floor in the starting zone and / or destination zone is advantageously determined. advantageously, If the input floors and / or the destination floors are compared with at least one selection criterion, and at least one input floor and / or destination floor, which best fulfills the selection criterion, is selected as the stopping floor.

This has the further advantage that any selection criteria, which further increase the delivery rate of the elevator installation, can be used. For specified calls, a stopping floor is selected as specific to the journey.

Advantageously, the operating costs of the journey from the starting zone to the destination zone are determined. Advantageously, the operating costs of the journey over the selected holding floor are determined.

This has the particular advantage that it is possible to determine variations of operating costs for a selected stopping floor. The operating costs are, for example, the travel costs of the elevator installation in the passenger's procedure. The minimization of the number of stops in the starting zone and / or in the target zone is thus quantified on the elevator installation side in variations of operating costs.

Advantageously, for each input floor and / or for each destination floor, which is not a selected stopping floor, substitution costs are determined from this input floor to the selected stopping floor of the starting zone and / or from this destination floor to the selected holding floor of the target zone. Advantageously, total substitution costs are determined for all input floors and / or for all destination floors which are not selected retaining floors.

This has the further particular advantage that it is possible to determine the costs of substitution incurred for a selected holding floor. Substitution costs are, for example, the travel costs which the passengers incur in order to switch from the input floor and / or destination floor to a selected one Haltestockwerk to arrive. The minimization of the number of stops in the start zone and / or in the destination zone is thus quantified in the passenger side in substitution costs.

Advantageously, differential costs are calculated from the difference between the operating costs of the journey from the starting zone to the destination zone and the operating costs of the journey via the selected stopping floor. Advantageously, the total substitution costs are compared with the difference costs. Advantageously, if the total substitution costs are greater than the difference costs, at least one further retaining floor is determined, otherwise the cabin is moved to the selected retaining floor.

All this has the advantage that the operating costs and the substitution costs are determined separately. The difference costs from the operating costs of the journey from the starting zone to the destination zone and the operating costs of the journey via the selected stopping floor correspond to a gross increase in the delivery rate. The subtraction of the total substitution costs from the difference costs provides a net increase in the delivery rate.

Advantageously, the calls are entered by the passengers in the form of destination calls on destination floors.

Advantageously, first calls are entered by the passengers on the input floors in the form of direction calls and further calls are entered by the passengers in the cabin in the form of car calls to destination floors.

This has the advantage that can be entered on the boarding floors both destination calls and direction calls, which makes the application area very wide.

Advantageously, the passenger is informed of the selected stopping floor. Advantageously, the passenger is the selected holding floor with at least one output device visually and / or acoustically communicated. Advantageously, the passenger is guided with the output device to the selected holding floor. Advantageously, status information of the elevator installation and / or route information for the selected retaining floor are output to the passenger on the output device.

This has the advantage that the passenger the way to the selected transfer floor is clearly and comprehensibly communicated. After all, it is the passenger who has to bear the substitution costs by walking down a staircase and / or escalator to the selected transfer floor.

Advantageously, the passenger input floors and / or destination floors, which are not selected holding floor, not or conditionally notified. Advantageously, the passenger input optics and / or destination floors, which are not selected holding floor, with at least one output device optically and / or acoustically not communicated.

This has the further advantage that the choice of floors is made easier for the passenger. Especially those floors that are not selected for the next ride of the cabin with relatively high probability as a holding floor or are not selected, the passenger is no longer or only partially communicated. A conditional message is, for example, a marking of the floor as <unselected landing floor>. The passenger thus does not even think of choosing such an unselected floor, but will choose a landing floor communicated to him. This simplifies and speeds up the call input, call allocation and call acknowledgment.

Advantageously, the method is iterative, that is, if the total substitution costs are greater than the differential costs, at least one further stopping floor is determined. Advantageously, for this purpose, each input floor and / or each destination floor, which is not a selected retaining floor is compared with at least one selection criterion. At least one input floor and / or at least one destination floor, which best fulfills the selection criterion, is selected as another retaining floor. The operating costs of the journey over the selected stopping floors are determined. For each input floor and / or for each destination floor, which is not a selected stopping floor, substitution costs are determined from this input floor to the at least one selected stopping floor of the starting zone and / or from this destination floor to the at least one selected holding floor of the target zone. For all input floors and / or for all destination floors, which are not a selected landing floor, total substitution costs are determined. Difference costs are determined from the difference between the operating costs of the journey from the starting zone to the destination zone and the operating costs of the journey via the selected stopping floors. The total substitution costs are compared with the difference costs. If the total substitution costs are greater than the difference costs, at least one additional stopping floor is determined, otherwise the car is moved to the selected stopping floors.

Advantageously, if a plurality of input floors and / or destination floors meet a selection criterion equally well, that of these input floors and / or destination floors selected as a holding floor and / or more holding floor, which meets at least one further selection criterion best.

Advantageously, a computer program product comprises at least one computer program means which is suitable for carrying out the method for allocating calls of an elevator installation and realizing that at least one method step is executed when it is present on at least one terminal and / or at least one mobile device and / or or at least one elevator control is executed. Advantageously, a computer-readable data memory comprises such a computer program product.

This is of particular advantage because it allows a simple and practical distribution of computer program resources to the various components of the elevator installation.

The elevator installation with at least one elevator and at least one cabin has according to Fig. 1 two elevators, each with a cabin 1, 1 'on. The cabins 1, 1 'are in elevator shafts of a building in the vertical direction, as indicated by directional arrows, movable. The building has a larger number of floors. According to Fig. 1 the cabins 1, 1 'serve forty-five floors S1 to S45. The passengers enter calls in input floors and are moved from the cars 1, 1 'in the building to individual destination floors. Other components of the elevators such as elevator drives of the cabins 1, 1 ', door drives of the cabins 1, 1', elevator doors, counterweights, propellant and suspension means, shaft information, etc. are not shown for the sake of clarity of illustration only.

An elevator control 4 has at least one processor and at least one computer-readable data memory and at least one electrical power supply. From the computer-readable data memory, at least one control computer program means is loaded into the processor and executed. The control computer program means controls the process of the cabins 1, 1 'via elevator drives and the opening and closing of the elevator doors via door drives. From the shaft information, the elevator control 4 receives information about the current position of the cars 1, 1 'in the elevator shafts. The person skilled in the art may use the present invention in any elevators with significantly more elevators, such as a group of six or eight elevators; with double and triple cabins; with several stacked, independently movable cabins per elevator shaft; with elevators without counterweight, with hydraulic lifts; etc. realize.

FIGS. 2 and 3 show two embodiments of a located on the floors S1 to S45 and / or in the cabins 1, 1 ' terminal 8 with mobile device 83 for entering the calls. For example, at least one terminal 8 is stationarily arranged near an elevator door on each floor. The terminal 8 is for example mounted on a building wall or is isolated in a space in front of the elevator door. In the housing of the terminal 8 at least one electronic reading device 80 and at least one output device 82 is arranged. In addition, at least one call input device 81 may be arranged in the housing of the terminal 8. The terminal 8 has at least one processor and at least one computer-readable data memory and at least one electrical power supply. At least one input / output computer program means is loaded into the processor from the computer readable data memory and executed. The input / output computer program means drives the electronic reader 80, the output device 82, and the call input device 81.

According to Fig. 2 For example, the terminal 8 has as call input device 81 keys with which destination floors can be accessed via number sequences such as <4> and <4> for the destination floor <44> can be entered manually. Alternatively, the terminal 8 may have, as a call input device 81, keys with which first calls in the form of direction calls such as <up> or <down> can be manually input. After entering the first calls on the boarding floor give the passengers in the car 1, 1 'at a further terminal 8 with call input device 81 and keys further calls in the form of car calls via appropriate number sequences by hand on destination floors.

According to Fig. 3 It is also possible to use a keyless terminal 8, in which the input of the destination floor is effected contactlessly by reading out a data memory of the mobile device 83 carried by the passenger through a suitable electronic reading device 80 in the terminal 8. The mobile device 83 is, for example, a Radio Frequency Identification Device (RFID) and / or a mobile telephone. As Fig. 2 shows, the non-contact call input and the call input can be combined via keys.

The mobile device 83 is carried by the passenger and is for example a mobile telephone and / or a computer with at least one transceiver. The mobile device 83 has at least one processor and at least one computer-readable data memory and at least one electrical power supply. From the computer-readable data memory at least one communication computer program means is loaded into the processor and executed. The communication computer program means controls the transmission and reception of the transceiver.

The terminal 8 and the mobile device 83 is / are connected via data lines via landline or radio network with the elevator control 4 or connectable. According to Fig. 3 the elevator controller 4 and the terminal 8 communicate in the fixed network, while the elevator controller 4 and the mobile device 83 communicate in the radio network. The terminal 8 transmits call information such as the input floor and the destination floor of a call to the elevator control 4. When entering a destination call or a Combination of a direction call and a car call, the elevator control 4 is thus informed that a passenger is to be moved from the input floor to the destination floor or the car call corresponding destination floor. The elevator control 4 transmits at least one call acknowledgment signal to the terminal 8 and / or the mobile device 83. The transmitted call acknowledgment signal can be output on the output device 82. The passenger thus receives an optical and / or acoustic call acknowledgment on the output device 82; the passenger preferably receives an optical and / or acoustic destination call acknowledgment.

According to Fig. 3 In addition, an output device 82 is arranged in the mobile device 83. The elevator control 4 transmits at least one holding floor signal to the terminal 8 and / or the mobile device 83. In the case of the mobile device 83, at least one input / output computer program means can be loaded and executed from the computer-readable data memory into the processor. The input / output computer program means controls the optical and / or acoustic output of the transmitted holding floor signal on the output device 82. The passenger is thus informed by the elevator control 4 about the selected stopping floor. The elevator control 4 transmits at least one state information signal via the elevator installation and / or at least one route information signal to the terminal 8 and / or the mobile device 83. The state information signal and / or the route information signal can be output optically and / or acoustically on the output device 82. Thus, the passenger receives from the elevator control 4 also status information about the elevator installation and / or route information, which lead him quickly and directly to the selected stopping floor. The state information also includes the display of input floors and / or destination floors which are not a selected landing floor. Such input floors and / or destination floors, which with relatively high probability are not holding floors during the next trip of the cabin, are not displayed on the output device 82 at all. The passenger will then do not enter such a non-displayed floor, so that he then also does not have to be notified that the floor entered is not a selected holding floor. The passenger can be informed on the occasion that he has to wait for a later trip of the cabin when he wants to be moved without substitution costs in a desired by him, not selected floor. Knowing the present invention, the person skilled in the art can also realize a lift system without a terminal, in which the mobile device 82, 83 with a call input device 81 integrated in the elevator control 4 or the elevator control 4 communicates directly with an output device 82 of the mobile device 83.

Known cellular telephone networks such as Global System for Mobile Communication (GSM) with frequencies of 900 to 1900 MHz can be used, but it is also possible to use near-field communication (NFC) radio networks. Known wireless networks are Wireless Local Area Network (WLAN) according to the standard IEEE802.11 or Worldwide Interoperability for Microwave Access (WIMAX) according to the standard IEEE802.16 with a range of several 100 meters to several 10 kilometers. The radio frequency used by the radio network is in a WLAN, for example, in the 2.4 GHz band or in the 5.0 GHz band and WIMAX in the 10 to 66 GHz band. Both the fixed network and the radio network allow bidirectional communication according to known and proven network protocols such as Transmission Control Protocol / Internet Protocol (TCP / IP) or Internet Packet Exchange (IPX). The landline has, for example, a plurality of electrical and / or optical data cables, which are laid in the building, for example, under plaster and so terminal 8 to connect the mobile device 83 and elevator control 4 with each other.

Fig. 4 shows a flowchart of a part of the method for allocating calls the elevator installation. In method step A , at least one start zone 9, 9 'with a plurality of input floors and at least one target zone 10, 10' with several are entered for the calls entered for a trip with the car 1, 1 ' Destination floors determined. According to Fig. 1 The car 1 moves a plurality of passengers from the starting zone 9, which is formed by the four input floors S41, S42, S44 and S45, into the destination zone 10, which is formed by the three destination floors S1, S2 and S3. And the car 1 'moves a plurality of passengers from the start zone 9', which is formed by the two input floors S1 and S2, into the destination zone 10 ', which is formed by the six destination floors S40, S41, S42, S43, S44 and S45. The entirety of the input stories form the start zone 9, 9 '. The totality of the destination floors form the target zone 10, 10 '.

From the computer-readable data memory of the elevator control 4 at least one operating cost computer program means is loaded and executed in the processor of the elevator control 4. The operating cost computer program means determines the operating costs of a trip with the car 1, 1 '. From the call information transmitted by the terminals, the service cost computer program means compiles a trip with the car 1, 1 'and lists for this trip the number of destination calls per destination floor as well as the number of destination calls or car calls per destination floor. According to Fig. 1 For the journey of the car 1, five passengers in the input floor S41 enter calls, a passenger enters a call in the input floor S42, two passengers enter calls in the input floor S44 and six passengers enter calls in the input floor S45. Of these fourteen passengers, eight passengers want the destination floor S1, one passenger wants to go to the destination floor S2 and five passengers want to go to the destination floor S3. Correspondingly, for the drive of the car 1 'eleven passengers in the input floor S1 enter calls and four passengers enter calls in the input floor S2. Of these fifteen passengers want two passengers in the destination floor S40, four passengers want to go to the destination floor S41, two passengers want to go to the destination floor S42, two passengers want to go to the destination floor S43, one passenger wants to get to the destination floor S44 and four passengers in the destination floor S45.

The operating costs of driving from the starting zone 9, 9 'in the target zone 10, 10' are minimized by reducing the number of stops in the starting zone 9, 9 'and / or in the target zone 10, 10'. At least one stopping floor in the starting zone 9, 9 'is determined and / or at least one stopping floor in the target zone 10, 10' is determined.

For this purpose, each input floor and / or each destination floor is compared with at least one selection criterion by the operating costs computer program means in method step B. The selection criteria are retrievable from a data store.

In method step C , the selection criterion is determined by the operating costs computer program means. Several selection criteria are explained in detail below:

Number of calls - This is how the number of calls entered per entry floor and / or destination floor serves as a selection criterion. At least one input floor and / or destination floor with the highest number of calls entered is selected as the landing floor. This selection criterion determines the smallest number of floor changes that passengers have to make. According to Fig. 1 For example, when the car 1 is traveling in the take-off zone 9, the six-call input floor S45 has the most calls, and in the destination zone 10, the eight-call destination floor S1 has the most calls, making these floors the landing floors. If a plurality of input floors and / or destination floors have the same number of calls entered, these input floors and / or destination floors are selected as holding floors. According to Fig. 1 When entering the car 1 'in the start zone 9', the input floor S1 with eleven calls has the most calls and in the destination zone 10 ', the two destination floors S41 and S45, with four calls, have the most calls, what these destination floors to stop floors in the target zone 10 '. If several input floors and / or destination floors enter an equal number of entries Having calls, so it is also possible to select those two input floors and / or two destination floors with the largest floor difference to each other as holding floors. According to Fig. 1 have in driving the car 1 'in the target zone 10', the three destination floors S40, S42 and S43 with two calls to the second highest number calls, the destination floors S40 and S44 have the largest floor difference to each other, what these destination floors to further stopping floors in the target zone 10 'makes. As already described, the calls can be both destination calls and direction calls of an input floor as well as destination calls or car calls of a destination floor.

Lowest absolute floor difference - The floor difference of the input floors to each other and / or the floor difference of the destination floors to each other serves as a selection criterion. In this case, the input floor with the lowest absolute floor difference to the other input floors and / or the destination floor with the lowest absolute floor difference to the other destination floors is selected as the landing floor. This selection criterion determines the shortest path that passengers have to overcome. According to Fig. 1 lie in the drive of the car 1 in the start zone 9, the two input floors S42 and S44 centrally between the input floors S41 and S45. To reach the input floor S44, six passengers must overcome a floor difference from the input floor S45, a passenger of the input floor S42 has to negotiate two floor differences, and five passengers of the input floor S41 have to negotiate three floor differences, resulting in a total of twenty-three absolute floor differences. To reach the input floor S42, the six passengers from the input floor S45 have to negotiate three floor differences, two passengers of the input floor S44 have to negotiate two floor differences and five passengers of the input floor S41 have to overcome a floor difference, giving a total of twenty-seven absolute floor differences. By which the input floor S44 is selected as a holding floor in the start zone 9.

Lowest relative floor difference - The floor difference of the input floors to each other and / or the destination floors to each other serves as a selection criterion. In this case, the input floor with the lowest floor difference to the other input floors and / or the destination floor with the lowest floor difference to the other destination floors is selected as the landing floor. This selection criterion determines the smallest increase in the building that passengers have to overcome. This takes into account that passengers prefer to go down stairs in the building (negative floor difference) than to go up (positive floor difference). According to Fig. 1 lie in the drive of the car 1 in the start zone 9, the two input floors S42 and S44 centrally between the input floors S41 and S45. To reach the input floor S44, six passengers of the input floor S45 must overcome a negative floor difference, a passenger of the input floor S42 must overcome two positive floor differences, and five passengers of the input floor S41 must overcome three positive floor differences, resulting in a total of eleven positive floor differences. To reach the input floor S42, the six passengers of the input floor S45 must overcome three negative floor differences, two passengers of the input floor S44 must overcome two negative floor differences and five passengers of the input floor S41 must overcome a positive floor difference, resulting in a total of seventeen negative floor differences. With which the input floor S42 is selected as a holding floor in the start zone 9.

Lowest or highest floor number - The floor number of the floors of the start zone 9, 9 'and / or in the target zone 10, 10' serves as a selection criterion. This selection criterion is based on the assumption that most passengers are on the floor with the lowest floor number and / or in the floor Floor with the highest floor number. Also, passengers prefer to walk down stairs in the building rather than climb up. When driving upwards, the floor with the lowest number of floors and / or the floor with the highest floor number is selected as the landing floor. When driving downhill, the floor with the highest number of floors and / or the floor with the lowest floor number is selected as the landing floor. According to Fig. 1 For example, when the car 1 is in the take-off zone 9, the highest-floor input floor S45 also has six calls, and in the destination zone 10, the lowest-floor destination floor S1 has the most calls, which makes these floors to landing floors.

Second lowest or second highest floor number - Again, the floor number of the floors serves as a selection criterion. This time, the selection criterion is based on the assumption that most passengers are on the second-lowest floor and / or on the second-highest-floor floor.

Lowest building floor difference - The floor difference between the input floors and the destination floors serves as a selection criterion. The input floor and the destination floor with the lowest floor difference are selected as landing floors. This selection criterion is based on the assumption that the lower the building floor difference, the faster the drive of the car 1, 1 'takes place. According to Fig. 1 For example, in the travel of the car 1 ', the input floor S2 has the highest floor number of the start zone 9', and the destination floor S40 has the lowest floor number, making these floors to landing floors.

Predefined input floor - According to this selection criterion, a predefined input floor and / or destination floor is selected as the floor.

Floor Substitution Costs - The amount of substitution costs of an input floor and / or destination floor, which is not a selected floor, serves as a selection criterion. For this purpose, either the input floor and / or destination floor with the greatest substitution costs per time unit is determined and / or the input floor and / or destination floor is determined whose substitution costs reach a threshold value. This selection criterion is based on the approach that all floors should receive the same as possible substitution costs. The time unit is freely selectable and is for example one week. The threshold is also freely definable, for example, one fifth of the floor number of the building.

Passenger license plate - Passenger license plate number of passengers is determined as a selection criterion. The determined passenger identifiers are compared with a value list. Passenger tags can be entered by the passenger at the terminal 8 by pressing keys of the call input device 81. Passenger license plates can also be detected without contact by reading the computer-readable data memory of the mobile device 82, 83. Other technical passenger tag detection capabilities, such as recognizing passenger biometric data and / or scanning a passenger's passport, are also applicable. A passenger license plate, which has the most value according to the value list, is determined. Thereupon, the input floor and / or the destination floor which selects the call of the passenger with the passenger number which has the most value as the stopping floor is selected. As a passenger license, for example, a VIP card and / or a disability card of a passenger is determined. According to the list of values, the presence of a VIP card and / or handicap card is given more value than the absence of a VIP card and / or handicap card. If several input floors and / or destination floors have a call from a passenger with a VIP card and / or handicapped ID card selects these input floors and / or destination floors as stopping floors.

Substitution costs - Passenger license plates are calculated as a sum of the passenger's substitution costs collected during a time unit. According to the list of values, the largest sum of the substitution costs of a passenger collected during a time unit is allocated the most value. This selection criterion is based on the approach that all passengers should bear as much as possible substitution costs. The time unit is freely selectable and is for example one week. Passengers who collect relatively high substitution costs in one week, ie travel a lot along stairs and / or escalators to selected stopping floors, will be compensated according to the list of values in a following week.

Random - According to this selection criterion, a random input floor and / or destination floor is selected as the retaining floor.

With knowledge of the present invention, it is up to the person skilled in the art to combine several of these selection criteria with one another to a selection criterion and / or to apply several of these selection criteria one after another in arbitrary sequences.

In method step D , at least one input floor and / or at least one destination floor, which best fulfills the selection criterion, is selected as the retaining floor. The operating costs computer program means processes at least one or more selection criteria in accordance with the predetermined calls on the input floors and / or destination floors and selects an optimal stopping floor in a specific way.

In method step E , the operating costs computer program means firstly determine the operating costs of the journey from the starting zone to the destination zone and, secondly, the operating costs of the journey via the selected holding floor determined. The operating costs are the travel costs of the elevator system in the process of passengers. The minimization of the stops in the starting zone and / or in the target zone is thus quantified on the elevator installation side.

In method step F , differential costs are determined by the operating costs computer program means, in which the difference between the operating costs of the journey from the starting zone to the destination zone and the operating costs of the journey via the selected holding floor are formed.

In method step G , the operating cost computer program means for each input floor and / or for each destination floor, which is not a selected holding floor, substitution costs of this input floor on the selected holding floor of the start zone 9, 9 'and / or from this destination floor to the selected Haltestockwerk the target zone 10, 10 'determined. For all input floors and / or for all destination floors, which are not a selected landing floor, total substitution costs are determined. Substitution costs are the travel costs incurred by the passengers in order to access a selected stopping floor from the input storey and / or destination storey. The minimization of the stops in the starting zone 9, 9 'and / or in the target zone 10, 10' is thus quantified on the passenger side.

In method step H , the total costs of substitution are compared with the difference costs by the operating costs computer program means. If the total substitution costs are greater than the difference costs, at least one further retaining floor is determined, otherwise the car 1, 1 'is moved to the selected retaining floor.

Method according to claim 3, characterised in that each input storey and/or each destination storey is or are compared with at least one selection criterion; and that at least one input storey and/or at least one destination storey, which best fulfils or fulfil the selection criterion, is or are selected as stopping storey.
5. Method according to claim 3 or 4, characterised in that the operating costs of the journey from the start zone (9, 9') to the destination zone (10, 10') are determined; and that the operating costs of the journey by way of the selected stopping storey are determined.
6. Method according to claim 5, characterised in that for each input storey and/or for each destination storey which is not a selected stopping storey substitute costs from this input storey to the selected stopping storey of the start zone (9, 9') and/or from this destination storey to the selected stopping storey of the destination zone (10, 10') are determined.
7. Method according to claim 6, characterised in that total substitute costs are determined for all input storeys and/or all destination storeys which are not selected stopping storeys.
8. Method according to claim 7, characterised in that difference costs are determined from the difference of the operating costs of the journey from the start zone to the destination zone (10, 10') and the operating costs of the journey by way of the selected stopping storey.
9. Method according to claim 8, characterised in that the total substitute costs are compared with the difference costs.
10. Method according to claim 9, characterised in that if the total substitute costs are greater than the difference costs at least one further stopping storey is determined; and that otherwise the cage (1, 1') is moved to the selected stopping storey.
11. Method according to claim 10, characterised in that each input storey and/or each destination storey which is or are not a selected stopping storey is or are compared with at least one selection criterion; that at least one input storey and/or at least one destination storey which best fulfils or fulfil the selection criterion is or are selected as further stopping storey; that the operating costs of the journey by way of the selected stopping storey are determined; that for each input storey and/or for each destination storey which is or are not a selected stopping storey substitute costs from this input storey to at least one selected stopping storey of the start zone (9, 9') and/or from this destination storey to at least one selected stopping storey of the destination zone (10, 10') are determined; that total substitute costs are determined for all input storeys and/or for all destination storeys which are not selected stopping storeys; that difference costs are determined from the difference of the operating costs of the journey from the start storey (9, 9') to the destination zone (10, 10') and the operating costs of the journey by way of the selected stopping storeys; that the total substitute costs are compared with the difference costs; that if the total substitute costs are greater than the difference costs at least one further stopping storey is determined; and that otherwise the cage (1, 1') is moved to the selected stopping storeys.
12. Method according to any one of claims 3 to 11, characterised in that the selected stopping storey is communicated to the passenger and/or input storeys and/or destination storeys which are not selected stopping storeys are not communicated to the passenger.
13. Method according to claim 4 or 11, characterised in that if several input storeys and/or destination storeys fulfil a selection criterion equally well that of these input storeys and/or destination storeys is selected as stopping storey and/or further stopping storey which best fulfils at least one further selection criterion.
14. Method according claim 4 or 11, characterised in that a storey number of the input storeys and/or destinations storeys is determined as selection criterion; and that the input storey with the second-lowest storey number and/or the destination storey with the second-highest storey number is or are selected as stopping storey.
15. Method according to claim 4 or 11, characterised in that the number of input calls per input storey and/or destination storey is determined as selection criterion; that a storey difference of the input storeys from one another and/or the destination storeys from one another is determined as selection criterion; that a storey number of the storeys in the start zone (9, 9') and/or in the destination zone (10, 10') is determined as selection criterion; that a level of the substitute costs of an input storey and/or destination storey which is or are not a selected stopping storey is determined as selection criterion; or that passenger identifications of the passengers are determined as selection criterion.
