It is a figure which shows an example of the structure which concerns on the train operation management system by 1st Embodiment. It is a figure which shows an example of the process sequence which concerns on the operation evaluation preparation process by 1st Embodiment. It is a figure which shows an example of the man machine screen by 1st Embodiment.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

(1) 1st Embodiment In FIG. 1, 1 shows the train operation management system by 1st Embodiment as a whole. The train operation management system 1 includes a man-machine terminal 101, a central processing unit 102, and a station I / F device 103.

  The man-machine terminal 101 transmits a user request (for example, a request for operation evaluation of a train operation plan) to the own terminal, or allows the user to understand the state of the terminal (for example, operation evaluation of a train operation plan). It is a device that can transmit for. The man-machine terminal 101 includes, for example, a computer (computer), and is not shown. A CPU (Central Processing Unit), a storage unit (RAM (Random Access Memory), a ROM (Read Only Memory), an HDD (Hard Disk) Drive), etc.), communication unit, input unit, output unit and the like.

  Functions of the man-machine terminal 101 (a prediction unit 108, a suggestion unit 109, an evaluation unit 110, and a man-machine unit 111 which is an example of a control unit that performs various controls) are described in, for example, a program in which a CPU is stored in a ROM. May be realized by reading out to RAM and executing (software), may be realized by hardware such as a dedicated circuit, or may be realized by combining software and hardware. Further, some of the functions of the man-machine terminal 101 may be realized by another computer that can communicate with the man-machine terminal 101.

  The communication unit is composed of, for example, a NIC (Network Interface Card), and performs protocol control during communication with the central processing unit 102. The input unit is a pointing device, a keyboard, or the like. The output unit is a display device, a speaker, or the like. The output unit may be an output device that outputs information to the storage unit, the recording medium, a preset e-mail address, or the like. The input unit and the output unit may be an integrated device such as a display with a touch panel.

  The central processing unit 102 manages the schedule diagram 105 indicating a train operation plan (for example, a daily implementation plan), or changes the operation corresponding to a location that cannot be operated according to the plan diagram 105 with respect to the plan diagram 105. A trial diagram (n) 121 indicating an operation plan when it is performed is created. Similar to the man-machine terminal 101, the central processing unit 102 includes a computer (computer), and functions (for example, a trial unit 107 described later) of the central processing unit 102 are realized by software, hardware, and the like. .

  The station I / F device 103 is a device that is installed in each interlocking station and controls the operation of the train. Similarly to the man-machine terminal 101, the station I / F device 103 includes a computer (computer), and the functions of the station I / F device 103 are realized by software, hardware, and the like.

(Example of control related to operation change)
The station I / F device 103 receives from the field equipment 104 the field condition (the signal signal display state, the track circuit falling on the rail, etc.). The station I / F device 103 transmits the field situation received from the field facility 104 to the central processing unit 102.

  The central processing unit 102 collects the site conditions acquired from each interlocking station. The central processing unit 102 creates a performance diagram 106 indicating an actual train operation result (information from the train operation start to the current time) using the aggregated field situation. The central processing unit 102 transmits a plan diagram 105 and a performance diagram 106 to the man-machine terminal 101. The central processing unit 102 stores the plan diagram 105 in the storage unit.

  The man-machine terminal 101 stores the planned diagram 105 and the actual diagram 106 received from the central processing unit 102 as the planned diagram 112 and the actual diagram 113 in the storage unit. The man-machine terminal 101 receives an input of operation change (change of the schedule diagram 105, operation arrangement, etc.) from the commander (an example of a user) via an input unit or the like. The man-machine terminal 101 transmits operation change input information to the central processing unit 102. As will be described later, the man-machine terminal 101 may transmit the operation change input information to the central processing unit 102 without receiving an input from the commander.

  The central processing unit 102 reflects the operation change input information in the plan diagram 105, and updates the plan diagram 105 to the plan diagram after the operation change. The central processing unit 102 creates route control information reflecting operation change input information. The central processing unit 102 transmits route control information to the station I / F device 103.

  The station I / F device 103 issues a control instruction to the field facility 104 in accordance with the route control information.

(Example of control related to operation evaluation)
The central processing unit 102 includes a trial unit 107. The man machine terminal 101 includes a prediction unit 108, a suggestion unit 109, an evaluation unit 110, and a man machine unit 111.

  The prediction unit 108 indicates the operation status of the train predicted from the plan diagram 112 and the result diagram 113 by taking into consideration the conditions (physical conditions, business conditions, etc.) on the operation of various trains based on the results. A prediction diagram 114 is calculated and transmitted to the man-machine unit 111.

  The proposing unit 109 detects a diagram disturbance and an unreasonable plan diagram 112 (a state in which the plan diagram 112 cannot actually operate), and creates a proposal for the diagram disorder or an unreasonable location.

  Regarding the diamond disturbance, the proposing unit 109 compares the planned diamond 112 and the predicted diamond 114, and detects the diamond disturbance from the difference in arrival and departure times. The proposing unit 109 determines that the schedule disturbance satisfies the proposal generation conditions (how much difference the diamond disturbance is determined may vary depending on the railway company, and the conditions for the diamond disturbance are provided). In this case, the disturbance occurrence location is stored as data of the proposal occurrence location 115. The proposing unit 109 also creates operation change method data (suggestion (n) 116) for recovering the diamond disturbance based on the diamond disturbance information indicating the diamond disturbance. In addition, since there may be a case where a plurality of types of proposals are created for one place where a proposal has occurred, it is represented as proposal (n) 116. Disturbance information includes turbulence patterns (the delay of the preceding direct train affects the subsequent direct train, the delay of the train before returning turns to the train after returning, etc.), and the equipment conditions of the station where the disturbance occurs (turnable station, retreatable station) Etc.) and the degree of disturbance (whether the delay time exceeded the threshold) or the like.

  For the irrational, the proposing unit 109 determines whether the planning diagram 112 is irrational. There are two types of irrational detection methods: arrival / departure order check and operation rule check. The order check is a method in which, in the planning diagram 112, when the arrival / departure order is reversed at a certain station, or when the arrival / departure order is reversed between stations, the presence / absence is “irrational”. The check of the operation rule is a method of making “unreasonable” when there is a schedule that is prohibited in operation, such as when the planning diagram 112 uses an entry prohibition number line. When the proposing unit 109 determines that there is an irrational part, the proposing part 109 stores it as data of the suggestion occurrence part 115. The proposing unit 109 also creates operation change method data (proposal (n) 116) for eliminating the unreasonableness based on the unreasonable information such as the train, station, and number line where the unreasonable occurrence occurs. For example, irrational information includes trains related to trains consisting of train operating sections, arrival / departure number / time of each station, type of train, number of trains, etc., whether passengers can return or evacuate, and passengers cannot pass This is a combination with a station / line related to whether it is a dedicated line or not. An unreasonable example of a combination of train information is that a plurality of trains use the same station / line at the same time. An example of an unreasonable combination of train information and station / number line information is to use a pass-only number line at a station where each station stops. A proposal that replaces an unreasonable combination with a combination that does not become unreasonable, such as by changing the arrival and departure times and use number lines, is an unreasonable proposal.

  When the proposing unit 109 detects a disorder or an irrational diagram, the proposing unit 109 transmits the proposing location 115 and the proposing (n) 116 to the man machine unit 111, and the man machine unit 111 transmits the proposing location 115 and the proposing (n). 116 is received. When the man machine unit 111 receives the information of the proposal occurrence location 115 from the proposal unit 109, the man machine unit 111 displays a proposal mark at the proposal occurrence location 115 on the display device (note that the proposal mark will be described later with reference to FIG. ). When the suggestion mark is selected by the commander via the input unit, the operation evaluation creation process is started.

  FIG. 2 is a diagram illustrating an example of a processing procedure related to the operation evaluation creation process.

  When the commander selects a proposal mark via the input unit, the man-machine unit 111 makes an operation evaluation creation request to the evaluation unit 110 (step S201).

  When the evaluation unit 110 receives the operation evaluation creation request from the man-machine unit 111, the evaluation unit 110 starts operation evaluation creation processing (step S202).

  Here, the operation evaluation includes an index value of one or a plurality of indices for evaluating a train operation plan, a cost of the index value, and the like. In the present embodiment, information of four types of indices (“average delay amount”, “power consumption”, “average boarding rate”, “average station congestion degree”) is stored in the storage unit as the index. Note that the index value of each index is calculated by acquiring data necessary for derivation of the index value (operation plan, current time, current train position, number of users appearing at the station, etc.).

  The average delay amount is the difference between the arrival time (in the schedule diagram 112) determined in the operation plan and the arrival time (in the prediction diagram 114) predicted from the current train position in each train and station to be proposed. That is, the average value of the delay is taken. The power consumption is a calculated value of the power required for the operation of all trains in each of the planning diagram 112 and the prediction diagram 114, and the power consumption of the prediction diagram 114 in which the traveling pattern of each train has changed is the planning diagram 112. Increase / decrease with respect to power consumption. The average boarding rate is calculated based on OD (Origin and Destination) data surveyed in advance, the number of users appearing at the station, etc., and the boarding rate of each section in each of the planned diamond 112 and the predicted diamond 114 Like the power consumption, the average boarding rate of the prediction diagram 114 increases or decreases with respect to the average boarding rate of the plan diagram 112. The average station congestion degree is calculated based on the OD data surveyed in advance, the number of users appearing at the station, and the like. Similarly to the power consumption, the average station congestion degree of the prediction diagram 114 increases or decreases with respect to the average station congestion degree of the plan diagram 112.

  Further, information on a cost conversion function for converting the index value of the index into a cost is stored in the storage unit. The man-machine unit 111 accepts addition, change, and deletion of the index and the cost conversion function stored in the storage unit through the operation of the input unit by the user. The cost conversion function for calculating the cost of each index value will be described later.

  The evaluation unit 110 acquires the plan diagram 112 and calculates (creates) operation evaluation (plan) 117 for all trains for the plan diagram 112 (step S203). For example, the evaluation unit 110 calculates the cost of the index value of one or more indexes for all trains for the plan diagram 112 according to the cost conversion function corresponding to each index, and calculates the total cost.

  The evaluation unit 110 acquires the performance diagram 113 and the prediction diagram 114, and calculates (creates) the operation evaluation (prediction) 118 for all trains for the performance diagram 113 and the prediction diagram 114 (step S204). For example, the evaluation unit 110 calculates the cost of the index value of one or more indexes for all trains for the performance diagram 113 and the prediction diagram 114 according to the cost conversion function corresponding to each index, and calculates the total cost.

  The evaluation unit 110 creates trial diagrams (n) 121 and the like for each type of proposal for a plurality of types of proposals (n) 116 related to the selected proposal mark. 107 is activated (step S205).

  The evaluation unit 110 transmits the proposal (n) 116 to the trial unit 107. The trial unit 107 creates a trial diagram (n) 121 as an operation plan (plan diagram 112) when the operation is changed from the plan diagram 105 and the proposal (n) 116 (step S206). The central processing unit 102 transmits a trial diagram (n) 121 to the man-machine terminal 101. The man-machine terminal 101 stores the trial diagram (n) 121 received from the central processing unit 102 as a trial diagram (n) 122 in the storage unit.

  The prediction unit 108 creates a trial prediction diagram (n) 123 from the performance diagram 113 and the trial diagram (n) 122 (step S207).

  The evaluation unit 110 acquires the trial diagram (n) 122 and calculates (creates) operation evaluations (trials) 119 for all trains for the trial diagram (n) 122 (step S208). For example, the evaluation unit 110 calculates the cost of the index value of one or more indices for all trains for the trial diagram (n) 122 according to the cost conversion function corresponding to each index, and calculates the total cost.

  The evaluation unit 110 acquires the performance diagram 113 and the trial prediction diagram (n) 123, and calculates the operation evaluation (trial prediction) 120 for all trains with respect to the performance diagram 113 and the trial prediction diagram (n) 123 (step S209). ). For example, the evaluation unit 110 calculates the cost of the index value of one or more indices for all trains for the performance diagram 113 and the trial prediction diagram (n) 123 according to the cost conversion function corresponding to each index, and calculates the total cost. calculate.

  The evaluation unit 110 finishes executing the processing from step S206 to step S209 for the number of proposals, and then evaluates operation evaluations 117 to 120 (operation evaluation (plan) 117, operation calculated in step S203, step S204, step S208, and step S209, The operation evaluation (prediction) 118, the operation evaluation (trial) 119, and the operation evaluation (trial prediction) 120) are transmitted to the man-machine unit 111 (step S210), and the operation evaluation creation process ends (step S211).

  Here, an example is given and demonstrated about a cost conversion function.

(A) Cost conversion function of average delay amount The cost caused by the delay is the “crew personnel cost” generated by the increase in crew due to operation changes for the purpose of delay recovery, and when transferring buses etc. when there is a significant delay There are two types of “transfer expense” generated in the example.

T1 [h] is the maximum delay time that does not require an increase in the number of crew members and transfers to other transportation facilities, t2 [h] is the maximum delay time that can be recovered only by the transfer of crew members, and t [h] is the average delay time If the total time during which the operation evaluation is calculated is T [h], the cost conversion function Ct of the cost caused by the delay is as follows.
(A1) 0 [h] ≦ t [h] <t1 [h]
Ct = 0 [k ¥]
(A2) t1 [h] ≦ t [h] <t2 [h]
Ct = Crew personnel cost [k ¥ / h] × T [h]
(A3) t2 [h] ≦ t [h]
Ct = (Crew personnel cost [k ¥ / h] × T [h]) + (Transfer destination cost [k ¥ / h] × T [h])

(B) Cost conversion function of power consumption The cost conversion function Cp of the cost with respect to the power consumption is as follows.
Cp = unit price of electricity bill [k ¥ / h] × power consumption [kWh]

(C) Cost conversion function of average boarding rate The cost generated by the average boarding rate is exemplified by a decrease in passenger satisfaction (service value) due to congestion deterioration.

A cost conversion function CN for the cost with respect to the boarding rate N [%], where Ns [%] is the reference boarding rate in the service plan, Nmax [%] is the boarding rate that is an allowable limit in service, and the boarding rate is N [%]. Is as follows.
(C1) 0 [%] ≦ N [%] <Ns [%]
CN = 0 [k ¥] (In the proposed operation evaluation, negative cost (passenger positive evaluation) due to congestion below the standard is excluded)
(C2) Ns [%] ≦ N [%] <Nmax [%]
CN = Congestion invalidity conversion factor [k ¥ /%] x (N-Ns) [%]
(C3) N [%] ≧ Nmax [%]
CN = ∞ [k ¥]

(D) Average Station Congestion Cost Conversion Function As an example of the cost generated by the average station congestion, one type of “personnel cost” related to admission control is given as an example.

Assuming that the station congestion level where entry restrictions occur is 100 [%], the total time during which the operation evaluation is calculated is T [h], and the average station congestion level is n [%], the average station congestion level n [%] The cost conversion function Cn for the cost is as follows.
(D1) 0 [%] ≦ n [%] <100 [%]
Cn = 0 [k ¥]
(D2) n [%] = 100 [%]
Cn = Labor cost [k ¥ / h] × T [h]

  And if the man-machine part 111 receives operation evaluation 117-120 from the evaluation part 110, based on the proposal (n) 116 and the operation evaluation 117-120 with respect to each proposal, the man-machine part 111 will evaluate the operation evaluation 117-120 with respect to each proposal. Display on the display device as a machine screen.

  FIG. 3 is a diagram illustrating an example of a man-machine screen. As shown in FIG. 3, the man machine unit 111 creates and displays a plan line 301 from the plan diagram 112, a result line 302 from the result diagram 113, and a prediction line 303 from the prediction diagram 114.

  The planned stripe 301 is displayed for the entire time zone of the stripe display area 304. The result line 302 is displayed for the time before the current time line 305 representing the current time. The prediction line 303 is displayed for the performance line 302 and the subsequent lines.

  When the man machine unit 111 receives the information of the proposal occurrence location 115 from the proposal unit 109, the man machine unit 111 displays the proposal mark 306 at the proposal occurrence location 115. When there are a plurality of proposal occurrence locations 115, a plurality of proposal marks 306 are displayed.

  The commander can select the proposal mark 306 via the input unit, and the man-machine unit 111 changes the proposal mark 306 to a mode (selection mark 307) in which numbers are added to the proposal mark 306 in order of selection. The proposal contents and the operation evaluation regarding the selection mark 307 are displayed in the proposal outline dialog 308. When there are a plurality of selection marks 307, switching display is performed with the proposal switching button 309 of the proposal overview dialog 308. FIG. 3 shows an example in which a proposal outline of the selection order “1” of the selection mark 307 is displayed.

  In FIG. 3, a display example 310 (“current state”) of the operation evaluation (prediction) 118 with respect to the performance diagram 113 and the prediction diagram 114, and proposals of the selection mark 307 (“order change”, “transfer change”, “canceling return”) A display example 311 of an operation evaluation (trial prediction) 120 for each of the trial prediction diagrams (n) 123 when each of the above is executed is shown.

  In the display example 310 (prediction diagram 114) of the operation evaluation (prediction) 118, the cost of the index value “50 minutes” of the index “average delay amount” is “1000 k ¥”, and the index value of the index “power consumption” The cost of “400 kWh” is “2000 k ¥”, the index value “200%” of the index “average boarding rate” is “10 k ¥”, and the index value “150%” of the index “average station congestion” It is indicated that the cost of “150 k ¥” is “3160 k ¥” and the cost (total cost) of all the index values is “3160 k ¥”.

  In the display example 311 of the operation evaluation (trial prediction) 120 (for example, a trial prediction diagram indicating an operation plan when the operation change of the proposal content “order change” is performed), the index value “10” of the index “average delay amount” The cost of the “minute” is “200 k ¥”, the cost of the index value “210 kWh” of the index “power consumption” is “1050 k ¥”, and the cost of the index value “150%” of the index “average boarding rate” is It is “7.5 k ¥”, the cost of the index value “110%” of the index “average station congestion degree” is “110 k ¥”, and the total cost is “1367.5 k ¥”. Yes.

  Here, the man-machine unit 111 can define and display the priority order of the proposal (n) 116 for each index. FIG. 3 shows a display example in which priority is given to the contents of the proposal (suggestion (n) 116) by paying attention to the cost of the index “average delay amount” among a plurality of indices. A proposal that minimizes the cost of the index “average delay amount” by selecting the priority order rearrangement button 312 is regarded as having the highest priority. In addition, about the kind of parameter | index to which attention is paid, it can be adjusted by a commander (addition, change, deletion).

  The operation evaluation for the plan (plan diagram 112 and trial diagram (n) 122) and prediction (actual diagram 113 and prediction diagram 114, and actual diagram 113 and trial prediction diagram (n) 123) is performed by a display switching button 313. The display can be switched by.

  When the commander selects the execution button 314, the man-machine unit 111 instructs the station I / F device 103 to execute the proposal with the highest priority (in this embodiment, the operation change input information is displayed in the center). To the processing device 102).

  Note that execution of the proposal is not limited to the above-described configuration. For example, the man-machine unit 111 proposes (n) so that the priority is higher as the total cost calculated by the evaluation unit 110 is lower. A priority order may be set for 116, and the operation change input information may be transmitted to the central processing unit 102 so that the proposal with the highest priority among the proposals (n) 116 is executed.

  When the central processing unit 102 receives the operation change input information, the central processing unit 102 overwrites the operation plan after the operation change on the plan diagram 105 before the operation change. As described above, the central processing unit 102 creates route control information reflecting the operation change input information, and transmits the route control information to the station I / F device 103. The station I / F device 103 issues a control instruction to the field facility 104 in accordance with the route control information.

  Further, after updating the plan diagram 105, the central processing unit 102 transmits the plan diagram 105 after the operation change and the latest result diagram 106 to the man-machine terminal 101. The proposing unit 109, the predicting unit 108, the man-machine unit 111, the trial unit 107, and the evaluation unit 110 repeat the processing based on the updated plan diagram 105 (plan diagram 112) and actual result diagram 113.

  According to the above-described configuration, for the operation change proposal created from the plan diagram, the plan diagram index value is cost-converted for each index type, and the trial diagram index value is cost-converted for each index type, Because it is displayed, it is possible to grasp the cost before and after execution of the schedule change operation. Further, according to the above-described configuration, for the operation change proposal created from the plan diagram and the forecast diagram, the index value of the actual diagram and the forecast diagram is converted into a cost according to the type of the index, and the index value of the actual diagram and the trial forecast diagram Is converted into costs for each type of indicator and displayed to the commander, so that the costs before and after the execution of the operation change of the prediction diagram can be grasped. According to such a configuration, since the commander can grasp the costs before and after the change for the plurality of proposals for operation change, the commander can quickly select a proposal for operation change with less loss for the railway company.

  Further, according to the above-described configuration, since the priority order is set based on the cost, the commander can easily select the proposal with less loss for the railway company.

  Further, according to the configuration described above, since the priority order is set based on the cost of the index desired by the commander, the commander can select an optimal proposal.

  In addition, according to the configuration described above, since the priority is set by calculating the total cost, it is possible to automatically execute the proposal of the operation change that becomes the most excellent comprehensive evaluation without waiting for the selection of the instructor. it can.

  According to the present embodiment, it is possible to quickly change the operation with little loss.
