2. Description of Related Art
A system for controlling facilities with various functions is known. For example, a system for controlling various functions of an airport is known.
In conjunction with the above description, an airport baggage processing system is disclosed in Japanese Laid Open Patent Application (JP-P2002-302259A). In this conventional example, there are a plurality of baggage claim fields in an airport of an arrival country. Which of the plurality of baggage claim fields in the airport of the arrival country is used is specified by a computer in a departure country. The specified baggage claim field is notified to passengers when an airplane takes off. Data showing the specified baggage claim field is notified to through a network. In the airport of the arrival country, the baggages of the passengers are unloaded from the airplane and transported to the specified baggage claim field.
Also, an apron control system is disclosed in Japanese Laid Open Patent Application (JP-P2001-167154A). In this conventional example, when a delay of an airplane is larger than a threshold, a detection control unit of the apron adjustment system determines whether a delay is caused in another airplane to be connected with the airplane. When the connection delay is caused, the detection control unit carries out an apron overlap detection process and a curfew out-of-time detection process. In the apron overlap detection process, whether an apron use time of the connection airplane overlaps that of the other airplane is determined. In the curfew out-of-time detection process, whether the arrival time of the connection airplane to the arrival airport and the departure scheduled time of a next connection airplane after a curfew finish time is determined. When the apron overlap is determined, the effect that the apron use times overlap is notified to the arrival airport. When it is determined to be curfew out-of-time, the effect that the arrival time or the departure time becomes curfew out-of-time is notified to the arrival airport.
Also, a security control system is disclosed in Japanese Laid Open Patent Application (JP-P2001-306659A). In the system of this conventional example, a passenger leaves a baggage to traffic transportation. An ID data for identifying a passenger is recorded to a storage media such as an. IC card and an IC tag at the time of reception of the baggage and the storage media are carried with the baggage and the passenger. Also, the location of the passenger is managed by using a non-contact type communication device with the storage media.

The simulation section 7 simulates a temporal flow of a target for every person (passenger) or for every baggage based on status data showing change of the person or baggage in position, i.e., movement by using an airport model showing a hardware configuration, an operation flow and a software configuration. Thus, the simulation section 7 simulates the congestion of persons or baggages left without being processed or transported, and the time change of the congestion and estimates future status data after several hours. Also, it is possible to simulate under assumption that the persons or baggages are fluid or fine particles. In such a case, the simulation is possible by applying the present invention to a simulator for fluid and the fine particles.
The evaluation section 9 detects a problem of the airport operation based on the future status data. A countermeasure for the estimated situation is selected. A situation after the countermeasure is applied is simulated by the simulation section 7 and the effectiveness of the countermeasure is verified. If there is not a problem, the evaluation section 9 outputs the countermeasure to the subsystems relating to the countermeasure.

The equipments and facilities shown with the above-mentioned node and link contain each equipment in each subsystem. Data from each equipment is stored in the airport control database 4 and is used by the airport simulation apparatus 6 according to the necessity.
As nodes (corresponding to 8b-1 and 8c-1), there are a lounge A41, a ticket issuing counter 42, a lounge B43, a check-in counter 44, a lounge C45, a carrying baggage checking counter 46, a security check 47, a departure immigration inspection 48, a lounge D49, a transit counter 52, a transfer baggage examination 53, a transit security check 54, restaurants A61-1 to D61-4, and powder rooms A62-1 to E62-5. On the other hand, as links (corresponding to 8d-1), there are main passages a1-1 to a1-n and a2 to a14, sub passages b1-l to b1-n, b2 to b9, c1-1 to c1-n, and c2 to c1. When this model is used for a simulation, the data stored in the node setting database 8b, the node setting database 8c, and the link setting database 8d of the simulation database 8 are used as the capabilities (throughputs) of each node and each link.
Next, an operation of the facilities control system according to the first embodiment of the present invention will be described with reference to the attached drawings.
(1) Step S21
The simulation section 7 reads out an airport model (
(2) Step S22
The simulation section 7 calculates an actual throughput at a current time at each node and each link in the airport. The calculation of the actual throughput of the node will be described, by using the check-in counter 44 as an example.
First, the equipment/staff-in-charge ID 4c-4 operating at the current time in the check-in counter 44 is acquired from the status database 4c. Subsequently, the throughput 4d-2 and the time function 4b-3 of the equipment/staff-in-charge ID 4d-1 corresponding to the equipment/staff-in-charge ID 4c-4 are acquired from the capability database 4d. The actual throughput is calculated from an equation of throughput 4d-2×time function 4b-3 (example: 0.5×f(t) persons/min., where f(t) is a function with respect to elapsed time t). In this case, evaluation with a higher precision can be carried out in accordance with the capability of a staff in charge, and the throughput contains a throughput of the staff in charge in addition to the throughput of the equipment. Moreover, further practical evaluation can be carried out because the change of capability with respect to time is contained as the time function.
The calculation of the actual throughput of the link will be described, using a passage after the procedure of the check-in counter 44 as an example. After the procedure of the check-in counter 44, the passenger goes to either of the following sections: the passage a5, the passage b5, and the passage c5. Therefore, the actual throughput of each passage is calculated. First, the processing speed 8d-2 and the speed function 8d-3 of each passage are acquired from the link setting database 8d. Subsequently, the actual throughput (m/sec.) is calculated from an equation of processing speed 8d-2×speed function 8d-3. In this case, because a deviation of passengers is contained in the function in addition to the throughput of the passage (the transportation capacity), evaluation with higher precision can be carried out. Also, which of the passages is used is set based on the selection probability 8d-4 of the node setting database 8c. Because the probability of the selection of the passage is introduced, the evaluation with higher precision can be carried out.
(3) Step S23
The status data showing the status of a target such as a passenger or baggage after a predetermined time is calculated. The predetermined time depends on the data processing capability of the apparatus and is 0.5 sec., for example.
When there are the targets aligned in a line before the check-in counter 44 of
(4) Step S24
The simulation section 7 outputs and stores the simulation result (the status data of the target) in a predetermined storage section (not shown). In accordance with the setting, the simulation result is displayed on the display unit 11. That is, the simulation is carried out every predetermined time and the simulation result is displayed.
(5) Step S25
Whether the simulation at the above steps S21 to S24 is carried out every predetermined time for a preset time (>predetermined time) is determined. When it is determined that the simulation is not carried out for the preset time, the control flow returns to the step S21. When it is determined that the simulation is not carried out for the preset time, the control flow advances to a step S26.
(6) Step S26
Whether the simulation of the above steps S21 to S25 is carried out to all the passengers in the airport while changing the target is determined. In this case, when the target arrives in the airport one after another from outside, these passengers who arrives in the airport for the preset time are contained in the targets. When the simulation is not carried out to all the passengers, the control flow returns to the step S21. When the simulation is carried out to all the passengers, the control flow ends. It should be noted that the number of passengers who enters the airport newly for the preset time is estimated from the quantity database 8a and is used for the simulation.
In the present invention, the movement of each target is simulated every predetermined time for the preset time. The movement of all the targets in the airport for the preset time can be simulated. Thus, the status of the airport after the preset time can be accurately grasped.
The evaluation with higher precision can be carried out to correspond to the actual situation because the capability (throughput 4d-2, time function 4b-3) of each of staffs in charge and equipments in each node is contained in the present invention. Also, the evaluation with higher precision can be carried out to correspond to the actual situation because a deviation in the movement of the target in each link is contained as the data (speed function 8d-3, selection probability 8d-4). This embodiment can be applied in the same way even if the object is the baggage.
As the nodes (corresponding to 8b-1 and 8c-1), there are the check-in counter 44, an explosive sensor field 80, a baggage transporting system A 81, a container A 82, a tag checking Field A 83, a transportation cart A 4, a transit transportation cart 88. On the other hand, as the links (corresponding to 8d-1), there are main transportation passages g1 to g6, and sub transportation passages g7 to g8. As the capability of each of nodes and links, the data stored in the node setting database 8b, the node setting database 8c, and the link setting database 8d of the simulation database 8 are used. The movement of the baggages unloaded from the arrival airplane can be simulated by using the airport model. In this case, the airport model is the same as that shown in
[Second Embodiment]
The facilities control system according to the second embodiment of the present invention will be described below.
As the nodes (corresponding to 8b-1 and 8c-1), there are an arrival immigration inspection field 71, a baggage claim field 72, a customs inspection field A73, a lounge E74, a restaurant E78, and powder rooms G79-1 to H79-2. On the other hand, as the links (corresponding to 8d-1), there are main passages d1 to d4, and d5-1 to d5-n, and subpassages f1 to f4 and e1 to e2. As the capability of each of nodes and links, the data stored in the node setting database 8b, the node setting database 8c, the link setting database 8d of the simulation data base 8 are used.
The operation of the facilities control system according to the second embodiment of the present invention is the same as that of the first embodiment, excluding that the airport model has the configuration shown in
As the nodes (corresponding to 8b-1 and 8c-1), there are a transportation cart B92, a tag checking filed B93, a container B94, a customs inspection field B95, a baggage transportation system B96, and a baggage claim field B97. On the other hand, as the link (corresponding to 8d-1), there are main transportation passages h1 to h6. As the capability of each of nodes and links, the data stored in the node setting database 8b, the node setting database 8c, and the link setting database 8d of the simulation database 8 are used. In this case, the airport model is the same as that of the second embodiment, excluding that the object is baggage. The airport model is one shown in
[Third Embodiment]
The facilities control system according to the third embodiment of the present invention will be described below.
Next, an operation of the facilities control system according to the third embodiment of the present invention will be described below.
(1) Step S01
The simulation section 7 reads out an airport model (
(2) Step S02
The simulation section 7 carries out the simulation of the time change of the status data by using the airport model and the status data. The simulation is carried out for a desired time period. That is, the status data showing a state of the target at each of nodes and links in the airport after the predetermined time period is calculated. This simulation is the same as in the first embodiment.
(3) Step S03
The simulation section 7 displays the status data indicative of a future status after the predetermined time period on the display unit 11 and stores in the predetermined storage section (not shown). Also, the simulation section 7 outputs the status data to the evaluation section 9.
(4) Step S04
The evaluation section 9 compares the simulated status of the target at each of nodes and links and an extraordinary situation (the third condition) 10a-1. When the extraordinary situation 10a-1 occurs, the control flow advances to a step S05. For example, when the security level at the airport is strengthened, a congestion of the target passengers occurs in the carrying baggage inspection field 46 and the security check inspection field 47. In the present invention, it is possible to grasp the increase of the targets with the time in the carrying baggage inspection field 46 and the security check inspection field 47, through the simulation and the estimation based on numerical equations. The occurrence of the congestion can be determined based on whether the targets exceed the reception possible quantity 8b-2 of the node setting database 8b. When the congestion does not occur at each node and each link, the control flow advances to a step S06.
(5) Step S05
The evaluation section 9 selects the countermeasure 10a-2 corresponding to the extraordinary situation 10a-1 based on a priority level 10a-3. The settings of each node and each link of the airport model are changed based on the countermeasure 10a-2. The countermeasure 10a-2 is to increase the number of operating equipments in the carrying baggage inspection field 46 and the security check inspection field 47 when the extraordinary situation 10a-1 is occurrence of the congestion in the carrying baggage inspection field 46 and the security check inspection field 47. After the countermeasure 10a-2 is applied, the simulation is carried out once again at the step S02. It should be noted that the countermeasure may be inputted from outside.
(6) Step S06
When the simulation for the countermeasure is not carried out, a data indicative of no problem in the current situation is outputted. The data is displayed on the display unit 11. In this case, it is possible to determine that there is no problem in the current situation even if the special situation occurs. When the simulation for the countermeasure is carried out, the countermeasure 10a-2 and a data indicating that there is no problem in the countermeasure 10a-2 are outputted. These data are displayed on the display unit 11. Also, the countermeasure 10a-2 is outputted to the relating subsystems. In the above example, an instruction is outputted to the safety control subsystem 20 to increase the number of operation equipments for the carrying baggage inspection 46 and the security check inspection 47.
Through the above processes, it becomes possible to estimate what extraordinary situation occurs, immediately after a special situation, i.e., the current situation or the virtual situation occurs in the airport. In addition, it becomes possible to instruct how to measure to the extraordinary situation and prevent occurrence of the extraordinary situation.
This embodiment may be applied in the same way even if the object is baggage. For example, the same effect as in the third embodiment can be achieved even if the airport model is

As for the passenger, there are the priority check-in counter 44a, a priority carrying baggage inspection field 46a, a priority security check inspection field 47a, and a priority departure immigration inspection field 48a, subsequent to a lounge C43 as the nodes (corresponding to 8b-1). Finally, the passenger goes toward the airplane via the boarding gate 50. On the other hand, as the links (corresponding to 8d-1), there are priority passages a15 to a24. However, the priority passage a21 comes from the check-in counter 44 in
As for the baggage, there are a priority explosive sensor inspection field 80a, a priority baggage transportation system 81a, a priority tag check field 83a and a priority transportation cart 84a. On the other hand, as the links (corresponding to 8d-1), there are priority transportation passages g9 to g16. However, the priority transportation passages g14 comes from the explosive sensor inspection field 80 in
Next, an operation of the facilities control system according to the fifth embodiment of the present invention will be described.
(1) Step S31
The simulation section 7 reads out the airport model (
(2) Step S32
The simulation section 7 carries out a simulation of the time change in the status data of passenger A and his baggage A by using the airport model based on the status data. The simulation is carried out until the passenger A arrives at the boarding gate and the baggage B is loaded into the airplane. That is, the status data of the passenger A when he arrives at the boarding gate and the status data of the baggage B when it is loaded into the airplane are calculated. This simulation is the same as in the first embodiment.
(3) Step S33
The simulation section 7 displays a future status of the passenger A when he arrives at the boarding gate and a future status of the baggage B when it is loaded into the airplane, on the display unit 11 and stores in the predetermined storage section (not shown). Then, the simulation section 7 outputs their status data to the evaluation section 9.
(4) Step S34
The evaluation section 9 compares the status data of the passenger A and the status data of the baggage A, and the departure time of the airplane on which the passenger A is going to board. When both of the passenger A and the baggage A are in the departure time of the flight, the control flow advances to a step S38. When either of the passenger A and the baggage A is not in departure time, the control flow advances to a step S35.
(5) Step S35
The evaluation section 9 checks whether or not there is a countermeasure to the situation, because either of the passenger A and the baggage A is not in the departure time. In this case, it is determined whether or not there is any priority procedure (
(6) Step S36
The evaluation section 9 adds an airport model shown in
(7) Step S37
When it is determined that either of passenger A and baggage A is not in the departure time of the flight even if all the priority procedures are used, a delay of the departure time of the flight is calculated based on the status data of the passenger A and the status data of the baggage A. The calculation result is displayed on the display unit 11, is stored in the predetermined storage section (not shown) and is displayed on a flight display unit.
(8) Step S38
When the priority procedures are carried out, the fact is displayed on the display unit 11 and outputted to each node and (portable phones of) concerned staffs such as a captain and flight attendants. When any priority procedure is not carried out, the effect is displayed on the display unit 11 and outputted to (the portable phones of) the concerned persons.
Through the above processes, it is possible to immediately determine what priority procedure should be taken in future, when the arrival of the passenger delays. In addition, when the arrival of the passenger A is not in the departure time of flight, the delay can be displayed to a flight display unit and notified to the concerned staffs. As a result, countermeasure can be speedily taken.
[Sixth Embodiment]
The facilities control system according to the sixth embodiment of the present invention will be described below.
Next, an operation of the facilities control system according to the sixth embodiment of the present invention will be described below.
(1) Step S41
The simulation section 7 reads out an airport model (
(2) Step S42
The simulation section 7 carries out a simulation of the time change in the status data by using the airport model based on the status data. The simulation is carried out for one year. That is, the status data is calculated to show the passengers and baggages at each link and each node in the airport for one year state. This simulation is the same as in the first embodiment.
(3) Step S43
The simulation section 7 displays the status data for one year on the display unit 11 and stores in the predetermined storage section (not shown). Also, the simulation section 7 outputs the status data to the evaluation section 9.
(4) Step S44
The evaluation section 9 determines whether any problem is in the statuses of each node and each link and the target passenger and baggage specified by the status data at each node and each link. The determination of presence of the problem is based on the following matters: an equipment operation percentage in each node is equal to or less than 70% and there is too large margin through the year, a congestion percentage of the target passenger and baggages at each link is equal to or less than 70% and there is too large margin through the year, an equipment operation percentage in each node is larger than 100% through the year, and a congestion percentage of the target persons and baggages at each link is larger than 100%. The control flow advances to a step S45 when there is too much margin or the congestion is easy to occur. The control flow ends when the state of too much margin or the congestion is not set at each node and each link.
(5) Step S45
The evaluation section 9 decreases the throughput of each link by a predetermined rate when the margin is too much. The evaluation section 9 increases the throughput of each link by a predetermined rate when the occurrence of congestion is predicted. The predetermined rate is stored in the storage section (not shown). After changing the throughput, the evaluation section 9 advances to the step S42 and carries out the simulation once again. It should be noted that the changed throughput may be inputted from outside.
Through the above processes, the field can be found where there is too much margin at the airport or the congestion is easy to occur. At the same time, it is possible to grasp how much the throughput should be changed to the field. Thus, the facilities and systems in the airport can be optimized.
As described above, the facilities control system using such a model of the airport ground facilities can be applied to the following cases.
(A) When the Congestion of the Passenger is Predicted.
It is predicted that the passengers are crowed in case of departure and arrival delays and strengthening a security. The prediction of the occurrence and change of congestion of the passengers is possible by changing the settings of the above nodes and the links and carrying out a simulation.
When a node or a link is found where the occurrence of congestion is predicted, it is possible to measure by applying appropriate countermeasures to equipments corresponding the nodes or links or equipments corresponding to the upstream or downstream of the node or link. For example, a node or link where the congestion of the passengers is predicted is assumed in the extraordinary situation 10a-1 of the countermeasure database 10a. The following countermeasusres 10a-2 are taken: the increase of throughput (operation percentage) of equipments at the node or link and equipments at the upstream or downstream of the node or link, increase of the number of equipments, operation start of spare equipments, increase of throughputs of staffs, increase of the number of staffs, and open of a spare space.
Thus, it is possible to achieve the avoidance of concentration of the passengers, improvement of satisfaction of passenger, the improvement of the safety of the passengers (avoidance of a panic), shortening of preparation time for departure, and increase of the number of taking-off and landing airplanes.
When a long-range simulation is carried out, it is possible to grasp problems of the facilities and equipments and to optimize the facilities and equipments.
(B) When the Non-Transported State of the Baggages is Predicted
The non-transported status of the baggage is predicted when a departure airplane and an arrival airplane are delayed and a security is strengthened. In this case, it is possible to predict change of non-transported status of the baggages by changing the settings of the above node and the link and by carrying out the simulation. When a node or link is found where the non-transported status of baggage is predicted, an appropriate countermeasure can be applied to equipments corresponding to the node or link or equipments corresponding to upstream or downstream of the node or link. For example, a node or link is found where the non-transported state of baggage is assumed in the extraordinary situation 10a-1 of the database 10-a. In this case, The following countermeasusres 10a-2 are taken: the increase of throughput (operation percentage) of equipments at the node or link and equipments at the upstream or downstream of the node or link, increase of the number of equipments, operation start of spare equipments, increase of throughputs of staffs, increase of the number of staffs, and open of a spare space. Thus, it becomes possible to achieve elimination of the non-transported state of the baggages, the shortening of boarding time for the baggages, earlier notification of departure predicted time, improvement of satisfaction of passengers, and increase of the number of taking-off and landing airplanes.

First, the facilities control system according to the seventh embodiment of the present invention will be described.
Next, an operation of the facilities control system according to the seventh embodiment of the present invention will be described.
(1) Step S11
The simulation section 7 acquires the settings of each node and each link from the node setting database 8b, the node setting database 8c, the link setting database 8d, and the capability database 8f. In addition, the flight data is acquired from the flight schedule database 8g.
(2) Step S12
The simulation section 7 reads out an airport model (e.g., shown in
(3) Step S13
The status data of the passenger and the baggage in case of the departure and the status data of the passenger and the baggage in case of the arrival are acquired from the quantity database 8a by the simulation section 7. In this case, the quantity database 8a shows a value estimated based on the flight schedule database 8g. A simulation is carried out for a future status data based on the current status data, by using the airport model. That is, the future status data is calculated to show statues of the target passenger and baggage at each node and each link in the airport after a predetermined time.
(4) Step S14
The simulation section 7 displays the future status data after the predetermined time on the display unit 11 and stores in the predetermined storage section (not shown). Also, the simulation section 7 outputs the status data to the evaluation section 9.
(5) Step S15
The evaluation section 9 compares the statues of the target person and baggage at each node and each link shown by the status data, and a state of an extraordinary situation (the third conditions) 10a-1. The control flow advances to a step S16 when the extraordinary situation 10a-1 occurs. The control flow advances to a step S17 when the extraordinary situation 10a-1 does not occur.
(6) Step S16
The evaluation section 9 selects one set of the countermeasures 10a-2 corresponding to the estimated situation 10a-1. The evaluation section 9 changes the settings of each node and each link of the airport model based on the countermeasures 10a-2 and stores in the storage section. The control flow advances to the step S12 and the simulation is carried out once again.
(7) Step S17
The simulation section 7 changes operation conditions and repeats the above steps S11 to S16. It should be noted that the simulation of step S13 is as described in the first embodiment.
