Description

  The present invention relates to a payout plan in which one or more torpedos that transport hot metal discharged from a blast furnace while passing through a plurality of steps and pay out at a payout place, and a payout start time are associated as charges. The present invention relates to a payout plan management apparatus, a payout plan management method, and a program.

  Conventionally, in factories such as integrated steelworks that have multiple blast furnaces and steel mills, the hot metal transported from the blast furnaces is transported in a form of a trolley called a topped car (hereinafter abbreviated as “toped”). Is called. Here, the flow of logistics between the blast furnace and the steelmaking factory in the factory will be described. First, the torpedo receives the output from the blast furnace (to receive), and the locomotive pulls it to each processing facility, and finally arrives at the dispensing place. Here, each torpedo is one or more each based on operating conditions (for example, preliminary processing for making hot metal into a component value required by a charge described later) until it arrives at the discharge station from the blast furnace. It passes through a process (that is, a processing facility that processes the process). Next, at the dispensing place, the hot metal is transferred from the topy to the pan. Then, the torpedo emptied by the payout is transported again under the blast furnace and waits for acceptance. On the other hand, in the pan where the hot metal has been transferred, the pan is transported to the converter (next step), where the hot metal is transferred to the converter. Here, one pot is counted as 1 charge (= 1 lot). The empty pot then waits for the next charge. In addition, the pot is operated while rotating several pieces, like Topid.

  In recent years, computerization has progressed, and the distribution of blast furnaces from the blast furnace to the steelmaking factory is carried out by computer simulations based on the process through which each toppe passes (hereinafter referred to as “passing process”). Technology has been developed to manage the hot metal discharge plan associated with dredging.

  For example, Patent Document 1 discloses a method for predicting supply of hot metal to a converter. In the technique of Patent Document 1, first, the prediction of the output of the blast furnace, the prediction of the amount discharged to the converter, the passage process, and the processing capacity of the equipment used are input. Then, the amount of molten steel produced per unit time estimated from the capacity of the equipment is predicted, and the amount of storage (the amount of molten iron retained between the blast furnace and the steelmaking plant) and its balance (the amount supplied before the converter) Predict.

JP 2003-82407 A

  In practice, however, the charge and the topies are linked as the operating conditions, and the predecessor of the topies is often performed. Moreover, in order to adjust the components of the molten steel that has been paid out, it is often the case that payouts are made from a plurality of topologies to one charge. Therefore, there is a problem that a phenomenon in which payout is delayed because a specific toppe has not arrived occurs. Due to delay in payout, once continuous casting occurs, the equipment is stopped for about 30 to 60 minutes, resulting in an opportunity loss for about one charge. Moreover, if the supply to continuous casting is not performed as planned, it will be difficult to perform efficient operations in the processes following continuous casting.

  The technique of Patent Document 1 aims to confirm the balance of storage amount before converter by performing simulation between the blast furnace and the steelmaking factory. Judgment of whether or not to pay out is based on only the pre-processed storage amount. Will do.

In addition, the arrow in a figure has shown the route of the process through which a toppe can pass.

First, the payout plan management apparatus according to the present embodiment will be described with reference to FIG. FIG. 1 is a block diagram showing a payout plan management apparatus according to the present embodiment.
As shown in FIG. 1, a payout plan management apparatus 1 according to the present embodiment includes a job information generation unit (job information storage unit) 10, a torpedo information storage unit (tope information storage unit) 11, and an equipment information storage unit. (Facility information storage means) 12, output amount prediction information storage section 13, simulation calculation section (payout arrival time prediction means) 20, guidance calculation section (payout delay detection means) 30, and payout plan information storage section (Payout plan registration unit) 31, guidance index storage unit 32, process change pattern information storage unit 33, guidance output unit (guidance display unit) 40, process change plan input unit (process change plan input unit) 50, And a result output unit 60.

  The torpedo information storage unit 11 is for storing the information on the torpedo that transports the molten iron as topped information. As the torpedo information, the hote information is given with information on the tope number, position, received amount (meaning the initial loading amount), and loading amount, and the process plan information is the scheduled passage process, processing equipment, standard processing time. Suppose that information on processing results is given. In this embodiment, it is assumed that there are 20 topies, and the hot metal information shown in Table 1 and the process plan shown in Table 2 are given to the topid numbers 1 to 20.

  In the process plan information in Table 2, information on processing facilities and start / end times is given for processes that have been processed, and information on candidate processing facilities and standard processing times is provided for unprocessed processes. Shall be registered.

  The equipment information storage unit 12 is for storing, as equipment information, processing equipment capable of processing each process of a physical distribution process using a torpedo between a blast furnace and a steelmaking factory and the capacity of each processing equipment. Here, it is assumed that a part of the processing equipment has an alternative relationship and can process the same process. In the present embodiment, the facility information shown in Table 3 is given.

  As shown in Table 3, in this embodiment, it is assumed that the processing capacity of each processing facility in each step is equal. In addition, since the time required for processing differs depending on the magnitude of component adjustment depending on the process, the processing capacity of the processing equipment in the process may be different. In such a case, information necessary for calculating the processing capacity may be provided in the facility information.

  The output amount prediction information storage unit 13 is for storing the output pitch (predicted value) of the blast furnace. In the present embodiment, both the blast furnace A and the blast furnace B have an output pitch of 30 minutes.

In the present embodiment, the schedule is created with the allocation priority as the equipment arrival order. The created schedule is shown in FIG. In creating the schedule, the transfer time between the processes was set to 5 minutes, and the upper limit of the number of torpedos that can be transferred at the same time was set to 10 due to the limitation of the number of topologies. In the present embodiment, the allocation priority is set to the equipment arrival order, but not limited to this, the order of steel output, the order of delivery date, etc. can be considered. Then, from the created schedule, the expected arrival time for each torpedo is calculated as shown in Table 6. The created schedule (see FIG. 3) is output to a result output unit 60 such as a display, a hard disk, or a printer via an output interface (not shown).

The payout plan information storage unit 31 is for storing a payout plan. Here, the payout plan is prepared in advance by another system or person, and is created within a range that satisfies the following rules.
・ The total amount paid out per charge does not exceed the pot capacity.
・ Select a combination of topologies that keeps the hot metal component value within the target charge value range.
In the present embodiment, it is assumed that the topped capacity is larger than the pan (charge) that receives hot metal in the dispensing step (step 6 in Table 3). In other words, if there is a difference in the capacity of the torpedo and if it is attempted to process without waste of hot metal, a state occurs in which a single charge is paid out from a plurality of topies. Therefore, in the present embodiment, it is assumed that payout is performed from one or two topies for one charge. In addition, it is assumed that a plurality of topies can be processed in parallel at the payout place (the number of topologies that can be processed simultaneously by other equipment is one). The payout plan in the present embodiment is shown in Table 5.

The guidance index storage unit 32 is for storing in advance a guidance reference value for outputting guidance as a guidance index. In the present embodiment, the guidance reference value is determined as follows.
-Guidance reference value of arrival delay torpedo A torpedo that arrives at the payout place is delayed by a certain time (15 minutes in this embodiment) or more.
-Guidance reference value exceeding the number of hot metal loaded toppeds When the number of hot metal loaded torpedo exceeds a certain number (10 in this embodiment) after a certain time (20 minutes in this embodiment), it arrives at the payout place. Specify the topped item that arrived at the earliest time among the unpaid topped items. However, if there is no unpaid toppedy that has arrived at the payout place, there is no target topped.

The process change pattern information storage unit 33 is for storing in advance, as process change pattern information, a process change proposal and its priority when outputting guidance. In the present embodiment, the above-mentioned guidance reference values stored in the guidance and notation part 32, that is, the guidance reference value for the arrival delay torpedo and the guidance reference value for the number of hot metal loaded topologies, and the priority thereof Is defined as follows.
-Process change plan of arrival delay topy If the process plan of arrival delay topy includes an omissible process (in this embodiment, only process 4), the omissible process is skipped. In the present embodiment, only the process 4 is specified as an omissible process, but when a plurality of omissible processes are set, the priority of each process is also set.
-Process change plan exceeding the number of hot metal loaded toppedes Disbursement is performed at a dispensing facility other than the normal dispensing site, and the torpedo is sent to the foundry to reduce the number of hot metal loaded torpedoes.

  The guidance calculation unit 30 compares the schedule created by the simulation calculation unit 20 (including the expected arrival time at each torpedo) with the payout plan information storage unit 31, and stores a guidance index storage unit 32 and process change pattern information storage. This is for calculating the guidance output from the unit 33. In the present embodiment, for the arrival delay tope, the expected payout arrival arrival time of each topic obtained from the schedule created by the simulation calculation unit 20 and the payout arrival target time obtained from the payout plan information storage unit 31 are compared. Then, the process change plan selected based on the priority stored in the process change pattern information storage unit 33 for the toppe designated based on the guidance reference value of the arrival delay topped stored in the guidance index storage unit 32. And output as guidance. For the hot metal loaded topped number, the hot metal loaded topped number after a certain time (20 minutes in the present embodiment) is calculated and stored in the guidance index storage unit 32 for the schedule created by the simulation calculation unit 20. The process change plan selected based on the priority stored in the process change pattern information storage unit 33 is output as guidance for the toppe designated based on the guidance reference value exceeding the hot metal loaded topped number. The payout place arrival target time is calculated from the payout plan information storage unit 31. That is, for each topic, the scheduled start time of the earliest charge paid out by that toppe is set as the payout arrival target time. However, when a plurality of topies pays out for the charge, the payout arrival target time is decremented according to the number. The carry-down time is assumed to be the charge processing scheduled time × (n−1) / n, where n is the number of topies to be paid out. For example, if the number of toppedies to be paid out is 3, payout place arrival target time = scheduled start time of charge + (scheduled end time of charge−scheduled start time of charge) × 2/3.

  The guidance output unit 40 is for outputting the guidance calculated by the guidance calculation unit 30. In the present embodiment, as shown in FIG. 3, the payout place A pays out almost as planned, but at the payout place B, the arrival of the topies 5 and 9 is delayed by 15 minutes or more, and the payout delay is delayed. You can see that it has occurred. Here, the Δ mark under each payout place shown in FIG. 3 indicates the payout place arrival target time. In addition, the arrow in the figure (marked with ← →) indicates the payout delay time of the difference between the payout arrival target time and the expected payout arrival time (those that exceed the guidance reference value of 15 minutes) (Shown with a thick arrow). That is, in this embodiment, guidance as shown in Table 7 is output.

  In the guidance of Table 7, the type of alarm (either the arrival delay toppe or the number of hot metal loaded topologies), the warning content (payout delay time or the number of hot metal loaded topologies), and the toppe specified by the guidance calculation unit 30 The selected plan change plan is displayed. If the alarm is an arrival delay topic, a charge causing a payout delay may be displayed during the guidance.

  The process change plan input unit 50 is for inputting a process change plan for the passing process with respect to the toppe displayed in the guidance output by the guidance output unit 40. Here, the input process change plan may be the process change plan displayed in the guidance output by the guidance output unit 40 or may be a process change plan that is uniquely considered. The input process change plan is stored as topped information (more specifically, process plan information) in the topped information storage unit 11. Then, based on the job generated by the job information generation unit 10 as a new process plan, a simulation is performed based on the simulation calculation unit 20, and the guidance calculated by the guidance calculation unit 30 is output again by the guidance output unit 40. Is done. In the present embodiment, based on the guidance shown in Table 7, FIG. 4 shows a simulation result when the process plans for topped 5 and topped 9 are changed (process 4 is omitted). As shown in FIG. 4, the payout delay of the topped 5 and the topped 9 is eliminated.

Next, the processing procedure of the payout plan management method using the payout plan management apparatus 1 according to the present embodiment will be described with reference to FIG. FIG. 5 is a flowchart illustrating the processing procedure of the payout plan management method according to the present embodiment.
Note that the processing of the payout plan management method according to the present embodiment described below can be read and executed by the CPU as a program in the computer as well. In addition, this program can be installed in various computer storage devices by recording it in a removable storage medium such as a CD-ROM, FD, or MO.

  As shown in FIG. 5, first, the torpedo information, the facility information, and the output amount prediction information are registered in the torpedo information storage unit 11, the facility information storage unit 12, and the output amount prediction information storage unit 13, respectively (step S1). : Topic information storage step, facility information storage step). Also, the payout plan information, the guidance index, and the process change pattern information are registered in the payout plan information storage unit 31, the guidance index storage unit 32, and the process change pattern information storage unit 33, respectively (step S2: payout plan registration step).

  Next, in the job information generating unit 10, job information is generated based on the topped information, facility information, and output amount prediction information registered in the topped information storage unit 11, the facility information storage unit 12, and the output amount prediction information storage unit 13. Is generated (step S3: job information storage step).

  Then, based on the job generated by the job information generation unit 10, the simulation calculation unit 20 creates a schedule, and calculates the expected payout arrival time at which each topic arrives at the payout point (step S4: arrival at the payout point). Time prediction step). The schedule created in the simulation calculation unit 20 is output to a display or the like in the result output unit 60 (step S5).

  Next, the payout plan information storage unit 31, the guidance index storage unit 32, and the payout plan information registered in the process change pattern information storage unit 33, the guidance index, the process change pattern information, and the simulation calculation unit 20 create Based on the schedule and the estimated payout arrival arrival time of each toppe, the guidance calculation unit 30 calculates the guidance to be output (step S6: payout delay detection step).

  The guidance calculated by the guidance calculation unit 30 is output by the guidance output unit 40 (step S7: guidance display step).

  And when changing a process about the toppe designated by the guidance output by the guidance output part 40 (step S8: YES), the process change proposal according to the guidance displayed on the guidance display part 40, or uniquely The considered process change plan is input and registered in the process change plan input unit 50 (step S9: process change plan input step), and the process returns to step S3. In addition, when a process change is not performed about the toppe designated by the guidance output by the guidance output part 40, or when a tope is not designated by the guidance output by the guidance output part 40 (step S8: NO) The process is terminated.

  As described above, according to the payout plan management apparatus, the payout plan management method, and the program according to the present embodiment, the capacity of the processing equipment stored in the equipment information storage unit 12 is taken into consideration, and the topped information in the topped information storage unit 11 is used. It is possible to accurately predict the arrival time of each torpedo at the payout place by performing a simulation in the simulation calculation unit 20 in units of jobs in which the stored passage processes for each torpedo are developed by the job information generation unit 10. Become. Then, based on a pre-planned payout plan, by comparing the scheduled payout start time with the expected torpedo arrival time of the torpedo linked to the charge, It is possible to know in advance whether there is an arrival delay.

  In addition, based on the payout plan registered in advance in the payout plan information storage unit 31, the payout arrival target time of each torpedo linked to the charge obtained from the scheduled payout start time of the charge, and the payout place of each torpedo By comparing the estimated arrival time with the guidance calculation unit 30, it is possible to detect in advance whether there is an arrival delay of a topeido that does not satisfy the reference value preset in the guidance index storage unit 32.

  In addition, by displaying the process change plan set in advance in the process change pattern information storage unit 33 as guidance, it is possible to take measures to prevent a delay in paying out the torpedo in advance.

  Further, based on the process change plan displayed as guidance in the guidance output unit 40 or the process change plan uniquely thought by the operator, the process change plan input unit 50 performs the process change of the passing process, so that This makes it possible to prevent the payout delay.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various modifications can be made as long as they are described in the claims.

Even in cases it can be applied.

  Further, in the above-described embodiment, the simulation calculation unit 20 creates a schedule by allocating the job selected based on the preset allocation priority to the processing equipment, but further considers the locomotive capability. In addition, it is preferable to create a schedule by allocating a job selected based on a preset allocation priority to a processing facility. That is, in the logistics by the toppe between the blast furnace and the steelmaking factory, the locomotive is pulling the toppe, and therefore, the topped exceeding the number of locomotives cannot be moved simultaneously. Therefore, in order to reflect the restriction on the locomotive capability in the simulation calculation unit 20, the locomotive and its capability (number) are registered in the facility information storage unit 12 as facilities, and the job information generation unit 11 carries them between the facilities. Is added to the job as one process. In the creation of the schedule in the simulation calculation unit 20, when the number of torpedo transported at the same time is likely to exceed the number of locomotives, priority is given to a transport command with high priority (topes), and a transport command with low priority is given. Try to wait. In addition, priority is set according to the process, for example, priority is given to unloading in order to increase transfer efficiency, and priority is given to items with a long waiting time in each transfer classification (loading and unloading). Various methods are possible. If the locomotive capacity is insufficient, a schedule satisfying the restrictions on the locomotive capacity can be obtained by assigning jobs to resources while deferring conveyance based on the set priority. Therefore, in the simulation calculation unit 20, it is possible to avoid simultaneous assignment of conveyances exceeding the number of locomotives.
