It is a figure which shows an example of the processing procedure which concerns on the operation evaluation creation processing by 1st Embodiment. It is a figure which shows an example of the man machine screen by 1st Embodiment.

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

(1) First Embodiment In FIG. 1, 1 indicates a train operation management system according to the first 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's request (for example, a request for operation evaluation of a train operation plan) to the own terminal, and makes the user understand the state of the own terminal (for example, an operation evaluation of a train operation plan). It is a device that can be transmitted for the purpose. The man-machine terminal 101 includes, for example, a computer, and is not shown. A CPU (Central Processing Unit), a storage unit (RAM (Random Access Memory), a ROM (Read Only Memory), and an HDD (Hard Disk). Drive), etc.), communication unit, input unit, output unit, etc.

The functions of the man-machine terminal 101 (prediction unit 108, proposal unit 109, evaluation unit 110, man-machine unit 111, which is an example of a control unit that performs various controls, etc., which will be described later) are, for example, programs in which the CPU is stored in ROM. It may be realized by reading the above into a RAM and executing it (software), it may be realized by hardware such as a dedicated circuit, or it may be realized by combining software and hardware. Further, a part of the functions of the man-machine terminal 101 may be realized by another computer capable of communicating 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, a recording medium, a preset e-mail address, or the like. Further, the input unit and the output unit may be an integrated device such as a display with a touch panel.

The central processing device 102 manages a plan timetable 105 showing a train operation plan (for example, a one-day implementation plan), or changes the operation of the plan timetable 105 corresponding to a part that cannot be operated according to the plan timetable 105. A trial timetable (n) 121 showing an operation plan at the time of the trip is created. Similar to the man-machine terminal 101, the central processing unit 102 is configured to include a computer (computer), and the functions of the central processing unit 102 (for example, the trial unit 107 described later) are realized by software, hardware, and the like. ..

The station I / F device 103 is a device installed at each interlocking station to control train operation. The station I / F device 103 is configured to include a computer (computer) like the man-machine terminal 101, 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 the on-site status (display state of the traffic light, falling of the track circuit, etc.) from the on-site equipment 104. The station I / F device 103 transmits the site status received from the site equipment 104 to the central processing unit 102.

The central processing unit 102 aggregates the site conditions acquired from each interlocking station. The central processing unit 102 creates an actual timetable 106 showing an actual train operation result (information from the start of train operation to the current time) using the aggregated on-site conditions. The central processing unit 102 transmits the planned timetable 105 and the actual timetable 106 to the man-machine terminal 101. The central processing unit 102 stores the planning timetable 105 in the storage unit.

The man-machine terminal 101 stores the plan timetable 105 and the result timetable 106 received from the central processing unit 102 in the storage unit as the plan timetable 112 and the result timetable 113. The man-machine terminal 101 receives an input of an operation change (change of a plan timetable 105, operation arrangement, etc.) from a commander (an example of a user) via an input unit or the like. The man-machine terminal 101 transmits the 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 the input from the commander.

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

The station I / F device 103 gives a control instruction to the on-site equipment 104 according to the course 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 proposal unit 109, an evaluation unit 110, and a man-machine unit 111.

The prediction unit 108 shows the train operation status predicted from the plan timetable 112 and the actual timetable 113, taking into account the operational conditions (physical conditions, business conditions, etc.) of various trains based on the actual results. The prediction timetable 114 is calculated and transmitted to the man-machine unit 111.

The proposal unit 109 detects the timetable disorder and the irrationality of the plan timetable 112 (a state in which the operation cannot actually be performed according to the plan timetable 112), and creates a proposal for the timetable disorder or the irrational part.

Regarding the timetable disorder, the proposal unit 109 compares the planned timetable 112 and the predicted timetable 114, and detects the timetable disorder from the difference in arrival and departure times. The proposal unit 109 has determined that the timetable disorder satisfies the proposal generation condition (note that the difference in the timetable disorder may differ depending on the railway company, and the condition for the timetable disorder is provided). In this case, the turbulence occurrence location is stored as the data of the proposal occurrence location 115. Further, the proposal unit 109 creates data (proposal (n) 116) of the operation change method for recovering the timetable disorder based on the timetable disorder information indicating the timetable disorder. Since there are cases where a plurality of types of proposals are created for one proposal occurrence location, the proposal (n) 116 is used. The timetable disturbance information includes the pattern of disturbance (the delay of the preceding direct train spreads to the following direct train, the delay of the train before turning back spreads to the train after turning back, etc.), and the equipment conditions of the station where the disturbance occurs (returnable station, evacuable station). Etc.), the degree of turbulence (whether the delay time exceeded the threshold), etc. are included.

Regarding irrationality, the proposal unit 109 determines whether or not there is irrationality with respect to the plan schedule 112. There are two types of irrational detection methods: checking the order of arrival and departure (or arrival and departure) and checking the operation rules. The order check is an unreasonable "yes" method in the planning timetable 112 when the arrival / departure order is reversed at a certain station or the departure / arrival order is reversed between stations. The check of the operation rule is a method of making it unreasonable "yes" when a timetable that is prohibited in operation is set, such as the plan timetable 112 using the entry prohibition line. When the proposal unit 109 determines that there is an irrational portion, it stores it as data of the proposal generation portion 115. Further, the proposal unit 109 creates data (proposal (n) 116) of the operation change method for eliminating the irrationality based on the irrational information such as the train, the station, and the track where the irrationality occurs. For example, irrational information is related to trains that consist of train operating sections, arrival / departure lines / times at each station, train types, number of trains, etc. It is a combination with stations and lines that consist of whether or not they are dedicated lines. An unreasonable example of a combination of train information is that multiple trains use the same station / line at the same time. An unreasonable example of the combination of train information and station / track information is to use a transit-only track at the station where the local train is located. A proposal to replace an unreasonable combination with a non-irrational combination by changing the arrival / departure time and the number of lines used is an unreasonable solution proposal.

When the proposal unit 109 detects the timetable disorder or irrationality, the proposal generation location 115 and the proposal (n) 116 are transmitted to the man machine unit 111, and the man machine unit 111 transmits the proposal generation location 115 and the proposal (n). 116 and is received. When the man-machine unit 111 receives the information of the proposal generation location 115 from the proposal unit 109, the man-machine unit 111 displays the proposal mark on the display device at the proposal generation location 115 (the proposal mark will be described later with reference to FIG. 3). ). When the proposal mark is selected by the commander via the input unit, the operation evaluation creation process is started.

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

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

Upon receiving the operation evaluation creation request from the man-machine unit 111, the evaluation unit 110 starts the operation evaluation creation process (step S202).

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

The average delay amount is the difference between the arrival / departure time (of the planned timetable 112) specified in the operation plan and the arrival / departure time (of the predicted timetable 114) predicted from the current train position at 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 electric energy required for the operation of all trains in each of the planned diamond 112 and the predicted diamond 114, and the power consumption of the predicted diamond 114 in which the traveling pattern of each train has changed is the planned diamond 112. Increases or decreases with respect to the power consumption of. The average occupancy rate is the occupancy rate of each section of each train in each of the planned timetable 112 and the predicted timetable 114, which is calculated based on the OD (Origin and Destination) data investigated in advance and the number of users appearing at the station. The average occupancy rate of the predicted timetable 114 increases or decreases with respect to the average occupancy rate of the planned timetable 112, as in the case of the electric energy consumption. The average station congestion is the average of the congestion of passengers waiting for trains at each station in each of the planned timetable 112 and the predicted timetable 114, which is calculated based on the OD data investigated in advance and the number of users appearing at the station. As with the power consumption, the average station congestion of the predicted timetable 114 increases or decreases with respect to the average station congestion of the planned timetable 112.

Further, the information of the cost conversion function for converting the index value of the index into the cost is stored in the storage unit. The man-machine unit 111 accepts additions, changes, and deletions 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 planned timetable 112 and calculates (creates) the operation evaluation (plan) 117 for all trains with respect to the planned timetable 112 (step S203). For example, the evaluation unit 110 calculates the cost of the index value of one or more indexes for all trains with respect to the planned timetable 112 according to the cost conversion function corresponding to each index, and calculates the total cost.

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

The evaluation unit 110 creates trial diamonds (n) 121 and the like when each proposal is executed for a plurality of types of proposals (n) 116 related to the selected proposal mark. Therefore, the evaluation unit 110 has as many trial units as the number of proposal types. 107 is started (step S205).

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

The prediction unit 108 creates a trial prediction diamond (n) 123 from the actual timetable 113 and the trial timetable (n) 122 (step S207).

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

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

After completing the processes from step S206 to step S209 for the number of proposals, the evaluation unit 110 calculates the operation evaluations 117 to 120 (operation evaluation (plan) 117, 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 is completed (step S211).

Here, the cost conversion function will be described with an example.

(A) Cost conversion function for average delay amount The costs incurred due to delay are the "labor cost of crew" incurred due to the increase in the number of crew members due to operational changes for the purpose of delay recovery, and the case of transferring buses, etc. when there is a significant delay. As an example, there are two types of "transfer destination costs" incurred in.

The maximum delay time that does not require the increase of crew members and transfer to other transportation means is t1 [h], the maximum delay time that can be recovered only by transferring crew members is t2 [h], and the average delay time is t [h]. Assuming that the total time during which the operation evaluation is calculated is T [h], the cost conversion function Ct of the cost generated 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 labor cost [k ¥ / h] x T [h]
(A3) t2 [h] ≤ t [h]
Ct = (crew personnel cost [k \ / h] x T [h]) + (transfer destination cost [k \ / h] x T [h])

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

(C) Cost conversion function of average occupancy rate An example of the cost generated by the average occupancy rate is a decrease in passenger satisfaction (service value) due to worsening congestion.

Assuming that the standard occupancy rate in the service plan is Ns [%], the occupancy rate that is the permissible limit in terms of service is Nmax [%], and the occupancy rate is N [%], the cost conversion function CN for the occupancy rate N [%] Is as follows.
(C1) 0 [%] ≤ N [%] <Ns [%]
CN = 0 [k ¥] (In the proposed operation evaluation, negative costs due to congestion below the standard (plus evaluation of passengers) are not considered.)
(C2) Ns [%] ≤ N [%] <Nmax [%]
CN = Congestion Utility Amount Conversion Factor [k ¥ /%] x (N-Ns) [%]
(C3) N [%] ≥ Nmax [%]
CN = ∞ [k ¥]

(D) Cost conversion function of average station congestion The cost generated by the average station congestion is, for example, one type of "labor cost" related to admission restrictions.

Assuming that the station congestion level where admission is restricted is 100 [%], the total time for calculating the operation evaluation is T [h], and the average station congestion level is n [%], the average station congestion level is n [%]. The cost conversion function Cn of the cost for is as follows.
(D1) 0 [%] ≤ n [%] <100 [%]
Cn = 0 [k ¥]
(D2) n [%] = 100 [%]
Cn = labor cost [k \ / h] x T [h]

Then, when the man-machine unit 111 receives the operation evaluations 117 to 120 from the evaluation unit 110, the man-machine unit 111 performs the operation evaluations 117 to 120 for each proposal based on the proposal (n) 116 and the operation evaluations 117 to 120 for each proposal. Display on the display device as a machine screen.

FIG. 3 is a diagram showing an example of a man-machine screen. As shown in FIG. 3, the man-machine unit 111 creates and displays the planned streaks 301 from the planned diamond 112, the actual streaks 302 from the actual diamond 113, and the predicted streaks 303 from the predicted diamond 114.

The plan streak 301 is displayed for all time zones of the streak display area 304. The actual streak 302 is displayed with respect to a time before the current time line 305 representing the current time. The prediction streak 303 is displayed for the actual streak 302 and later.

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

The proposal mark 306 can be selected by a commander or the like via an input unit, and the man-machine unit 111 changes to a mode in which the proposal mark 306 is numbered in the order of selection of the proposal mark 306 (selection mark 307). The content of the proposal and the operation evaluation regarding the selection mark 307 are displayed in the proposal summary dialog 308. When there are a plurality of selection marks 307, switching display is performed by the proposal switching button 309 of the proposal summary dialog 308. Note that FIG. 3 shows an example in which the outline of the proposal 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 (forecast) 118 for the actual timetable 113 and the forecast timetable 114 and a proposal of the selection mark 307 (“order change”, “transfer change”, “discontinuation turnaround”” are shown. ) Is executed, the display example 311 of the operation evaluation (trial prediction) 120 for each of the trial prediction diamonds (n) 123 is shown.

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

In the display example 311 of the operation evaluation (trial prediction) 120 (for example, the trial prediction timetable showing the 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 "minutes" is "200k ¥", the cost of the index value "210kWh" of the index "power consumption" is "1050k ¥", and the cost of the index value "150%" of the index "average occupancy rate" is It is shown that the cost is "7.5k \", the cost of the index value "110%" of the index "average station congestion" is "110k \", and the total cost is "1367.5k \". There is.

Here, the man-machine unit 111 can define and display the priority of the proposal (n) 116 for each index. FIG. 3 shows a display example in which the content of the proposal (proposal (n) 116) is prioritized, focusing on the cost of the index “average delay amount” among the plurality of indexes. By selecting the priority order sorting button 312, the proposal that minimizes the cost of the index "average delay amount" is regarded as having the highest priority. The type of index of interest can be adjusted (added, changed, deleted) by the commander.

Further, the operation evaluation for the plan (planning timetable 112 and trial timetable (n) 122) and prediction (actual timetable 113 and prediction timetable 114, and actual timetable 113 and trial prediction timetable (n) 123) is displayed by the 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 having the highest priority (in the present embodiment, the operation change input information is centralized). (Send to processing device 102).

The execution of the proposal is not limited to the above configuration. For example, the man-machine unit 111 has a higher priority as the total cost calculated by the evaluation unit 110 is lower. The priority may be set in 116, and the operation change input information may be transmitted to the central processing unit 102 so as to execute the proposal having the highest priority among the proposals (n) 116.

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 with the plan timetable 105 before the operation change. As described above, the central processing unit 102 creates the course control information reflecting the operation change input information, and transmits the course control information to the station I / F device 103. The station I / F device 103 gives a control instruction to the on-site equipment 104 according to the course control information.

Further, after updating the planned timetable 105, the central processing unit 102 transmits the planned timetable 105 after the operation change and the latest actual timetable 106 to the man-machine terminal 101. The proposal unit 109, the prediction unit 108, the man-machine unit 111, the trial unit 107, and the evaluation unit 110 repeat the process based on the updated plan diamond 105 (plan schedule 112) and actual schedule 113.

According to the above configuration, for the operation change proposal created from the planning timetable, the index value of the planning timetable is cost-converted by the type of the index, the index value of the trial timetable is cost-converted by the type of the index, and the commander is informed. Since it is displayed toward the target, it is possible to grasp the cost before and after the execution of the operation change of the planned timetable. In addition, according to the above configuration, for the operation change proposal created from the planned timetable and the forecast timetable, the index values of the actual timetable and the forecast timetable are cost-converted for each type of the index, and the index values of the actual timetable and the trial forecast timetable are converted. Is converted into costs for each type of index and displayed to the commander, so it is possible to grasp the costs before and after the execution of the operation change of the forecast timetable. According to this configuration, the commander can grasp the cost before and after the change for a plurality of operation change proposals, so that the commander can quickly select the operation change proposal with less loss for the railway company.

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

Further, according to the above-described configuration, the priority is set based on the cost of the index desired by the commander, so that the commander can select the optimum proposal.

In addition, according to the above configuration, the total cost is calculated and the priority is set, so that the proposal for the operation change, which is the best comprehensive evaluation, can be automatically executed without waiting for the commander's selection. can.

According to this embodiment, it is possible to quickly change the operation with less loss.
