Description

  The present invention relates to a part repair work management apparatus, a part repair work management method, and a part repair work management program.

  An apparatus that requires regular maintenance is, for example, a gas turbine. In a gas turbine, it takes time to maintain hot parts such as a stationary blade, a moving blade, and a combustor. For this reason, there is a method of performing maintenance by preparing the same part as the part to be maintained as an alternative part during maintenance. In this method, the parts to be maintained can be removed from the gas turbine, the replacement parts can be attached, and the gas turbine can be operated. Therefore, the parts to be maintained can be maintained while the gas turbine is operating. Here, in the maintenance of the gas turbine, after removing the parts to be maintained from the gas turbine, the inspection is performed, the content of the repair to be performed is determined, and the repair is performed. Workers who perform repairs receive repair costs as compensation for repair work.

  Patent Document 1 describes a repair fee calculation system. In the repair fee calculation system, if the device is delivered from the manufacturer to the business owner and the repair is started after the repair contract is made, it will be necessary to repair the device from the time of operation by the operation time calculation processing unit. The operation time until the occurrence of the problem is calculated, and the required repair fee calculation processing unit calculates the required repair fee from the operation time and the repair unit price per operation time stored in the storage unit, and calculates the repair fee to be paid The paid repair fee is calculated by subtracting the paid repair fee stored in the storage unit from the necessary repair fee by the processing unit.

Further, the repair information 163 may hold information on the cost of the repair.

  The operation information 164 holds information related to the operation of each gas turbine.

Here, the degree of repair is the content of repair work performed on the part. The degree of repair in this embodiment is based on the cost of repair.

  FIG. 2 is a graph for explaining an example of the repair evaluation parameter. The repair evaluation parameter shown in FIG. 2 is a graph showing the relationship between the ratio of the degree of repair and the operation time. In FIG. 2, the degree of repair is divided into four stages of no repair, L repair, M repair, and H repair. FIG. 2 shows an evaluation value (predicted value) as to which ratio of parts to be repaired is generated, assuming that a set of all parts to be repaired of the gas turbine is 100%. In each operation time, the width from the ratio 0% to the point without repair corresponds to the proportion of parts without repair, the width from the point without repair to the point of L repair corresponds to the proportion of parts with L repair, The width from the L repair point to the M repair point corresponds to the ratio of the M repair parts, and the width from the M repair point to the H repair point corresponds to the ratio of the H repair parts. No repair is an evaluation that there is no need for repair and that it can be mounted on a gas turbine as it is. Further, the L repair is an evaluation that a light repair, specifically, a repair that requires more cost than no repair is necessary. M repair is an evaluation that middle repair, specifically, repair that requires more cost than L repair is necessary. The H repair is an evaluation that a heavy repair, specifically, a repair that is more expensive than an M repair is necessary. The repair evaluation parameter shown in FIG. 2 indicates a transition of the ratio of the degree of repair of the part, which varies depending on the operation time. The parts installed in the gas turbine are more expensive and require more repairs as the operating time becomes longer. In FIG. 2, only the correspondence relationship between the operation time and the degree of repair is shown, but the number of activations, the number of trips, and the load during operation may be taken into account. In this case, the repair evaluation parameter 165 may store the relationship between the operation information so that the correspondence relationship used in one operation information is specified and the other operation information can be converted and added. Further, a multidimensional map may be stored so that the ratio of the degree of repair that matches each operation information can be specified.

  The part repair work management program 169 provides a function for creating a suitable production plan. The part repair work management program 169 includes a repair degree prediction unit 169a, a predicted repair cost calculation unit 169b, an actual repair cost calculation unit 169c, and a repair work management unit 169d.

  The repair level prediction unit 169a provides a function of predicting the level of repair of components included in the gas turbine to be maintained. In this embodiment, the repair degree prediction unit 169a acquires the configuration, repair history, and past operation history of the parts of the gas turbine to be maintained based on the configuration information 161, the client information 162, the repair information 163, and the operation information 164. To do. In addition, the repair degree prediction unit 169a determines whether the target gas turbine is based on information received from the terminal 21 via the communication unit 13, information input to the input unit 12, or information read by the medium reading unit 14. Get operational information. The repair degree prediction unit 169a predicts the ratio of the repair degree of each component by analyzing the information acquired based on the repair evaluation parameter 165. The repair degree prediction unit 169a is not limited to the above method. Another example of a method for predicting the degree of repair of parts will be described later. The repair degree prediction unit 169a transmits information on the proportion of the predicted degree of repair of the component to the predicted repair cost calculation unit 169b.

  The predicted repair cost calculation unit 169b provides a function of calculating a predicted value of the cost of repair of a part that predicts the degree of repair of the target gas turbine, that is, a predicted repair cost. Specifically, the expected repair cost calculation unit 169b obtains the model number of the target gas turbine from the client information 162, and calculates the total number of repair target parts of the gas turbine and the repair cost for each degree of repair from the configuration information 161. get. The expected repair cost calculation unit 169b calculates the number of parts for each repair level based on the ratio of the repair level predicted by the repair level prediction unit 169a and the total number of repair target parts of the gas turbine, By multiplying the number of parts by the repair cost for each degree of repair, and summing them up, a predicted repair cost that is a predicted value of the total repair cost of the parts at the time of maintenance of the gas turbine is calculated.

  The actual repair cost calculation unit 169c provides a function of calculating an actual cost required for repair of a target gas turbine component, that is, an actual repair cost. Specifically, the actual repair cost calculation unit 169c acquires the repair cost for each degree of repair from the configuration information 161, and acquires the content of actual repair of the part from the repair information 163 or the outside. The actual repair cost calculation unit 169c multiplies the repair cost by the number of parts that have been repaired for the degree of each repair, and then adds up the actual repair costs that are the total repair costs for the maintenance of the gas turbine. Is calculated. When the actual repair cost calculation unit 169c acquires the actual repair content from the outside, the actual repair content is stored in the repair information 163. Thereby, the repair information 163 is updated.

  The repair work management unit 169d provides a function of managing information related to part repair work. The repair work management unit 169d stores various pieces of information acquired from the outside in the configuration information 161, the client information 162, the repair information 163, the operation information 164, and the repair evaluation parameter 165. In addition, the repair work management unit 169d deletes or updates the information of the configuration information 161, the client information 162, the repair information 163, the operation information 164, and the repair evaluation parameter 165 based on various information acquired from the outside. Or add.

  In addition, the repair work management unit 169d of the present embodiment detects a difference between the predicted repair cost calculated by the predicted repair cost calculation unit 169b and the actual repair cost calculated by the actual repair cost calculation unit 169c. The repair work management unit 169d stores the detected difference information in the repair information 163. In addition, the repair work management unit 169d detects a difference between the ratio of the repair level predicted by the repair level prediction unit 169a and the ratio of the actual repair level, and based on the detected difference, the repair evaluation parameter 165 Correct the information. For the correction, a difference between the predicted predicted repair cost and the actual repair cost may be used.

  With reference to FIGS. 3 to 8, a part repair work management processing procedure executed by the part repair work management apparatus 10 will be described. FIG. 3 is a flowchart showing a processing procedure of parts repair work. First, with reference to FIG. 3, a maintenance process for gas turbine parts, that is, a part repair work process will be described. Note that the process shown in FIG. 3 is performed by an operator in each process. The workers in each process may be the same or different.

  First, in step S10, the worker removes a part to be repaired from the apparatus, that is, the gas turbine. Here, as a part, there exist a moving blade, a stationary blade, and a combustor as mentioned above. When the worker removes the part from the gas turbine, he or she installs a replacement part (a repaired part, a part that does not require repair, a new part, etc.). Thereby, the time which stops a gas turbine can be shortened. When the gas turbine may be stopped for a long period of time, the removed parts may be repaired, and the repaired parts may be attached and restarted.

  After removing the parts in step S10, the operator transports the removed parts to the repair site in step S12. That is, it is transported to a place where the parts are repaired, for example, a factory or a processing site. When the operator transports the part to the site in step S12, the worker processes the target part into a state where it can be inspected in step S14. For example, the worker removes a treatment applied to the surface of the component, for example, a heat resistant coating (TBC). When the worker processes the target part in a state where the target part can be inspected in step S14, the worker inspects the target part in step S16. Here, as the inspection, visual inspection VT (Visual Testing), fluorescent penetrant testing FPT (Fluorescent Penetrant Testing), and the like are performed to determine whether the part is cracked or damaged. When the worker inspects the target part in step S16, the content of repair to be performed for each target part is determined based on the result of the inspection in step S18. The repair contents include various repairs, and are classified into the above-described four repairs according to the degree of damage, for example. When the worker determines the repair contents in step S18, the worker calculates an estimate of the repair cost in step S20. When the operator makes an estimate in step S20, the operator negotiates with the user of the gas turbine, and determines the repair contents and repair cost in step S22. At this time, the contents and cost of repair may be changed by negotiation. When the worker determines the repair contents and the repair cost in step S22, the worker performs repair work in step S24 and delivers the repaired target part in step S26.

  The parts of the gas turbine to be maintained are repaired through the above-described processes. Here, the process shown in FIG. 3 is performed by inspecting a target part, calculating an estimate based on the result, negotiating repair contents based on the estimate, and performing repair based on the result. Yes. For this reason, it takes time to start the repair work after removing the part.

  Next, FIG. 4 is a flowchart showing a processing procedure of the component repair work management apparatus 10. The processing procedure shown in FIG. 4 is realized by the control unit 15 executing the component repair work management program 169.

  The control part 15 acquires the operation information of the target apparatus as step S30. That is, the control unit 15 acquires operation information of a gas turbine that performs maintenance, that is, a gas turbine from which a part to be repaired is removed. As described above, the control unit 15 can acquire operation information based on communication via the communication unit 13, input via the input unit 12, and data stored in the storage unit 16. That is, in the part repair work management apparatus 10, at least one of the communication unit 13, the input unit 12, and the storage unit 16 serves as an operation information acquisition unit.

  After acquiring the operation information in step S30, the control unit 15 predicts the repair level (the level of repair) as step S32. Specifically, the control unit 15 uses the repair evaluation parameter to calculate the degree of repair of the part corresponding to the acquired operation information, that is, the prediction of the ratio of the degree of each repair to the part to be repaired.

  After predicting the degree of repair in step S32, the control unit 15 calculates a predicted repair cost based on the predicted degree of repair in step S34. Specifically, the control unit 15 calculates the number of parts having the degree of each repair based on the predicted ratio of the degree of repair and the number of parts, and further adds the cost of the repairs to each and totals them. The estimated repair cost is calculated.

  After calculating the predicted repair cost in step S34, the control unit 15 outputs the calculated predicted repair cost in step S36. Note that the output destination of the predicted repair cost can be set at various positions depending on the setting. Examples of the output destination include the terminal 21 and the display unit 11. For example, the parts repair work management apparatus 10 is set to output to the terminal 21 when the predicted repair cost is presented to the user of the apparatus. The parts repair work management apparatus 10 is set to output to the display unit 11 when the predicted repair cost is presented to an operator who performs repair.

  After outputting the predicted repair cost in step S36, the control unit 15 acquires actual repair information as step S38. Specifically, the control unit 15 acquires the content of the repair work actually performed on the part from the repair information 163 in the outside or the storage unit 16. After acquiring the actual repair information in step S38, the control unit 15 calculates the actual repair cost as step S40. Specifically, the control unit 15 calculates the actual repair cost by adding the cost of repairs to the number of parts that are actually repaired and totaling them.

  After calculating the actual repair cost in step S40, the control unit 15 stores the difference between the calculated predicted repair cost and the actual repair cost in step S42. The control unit 15 calculates a difference between the calculated predicted repair cost and the actual repair cost, and stores the calculated difference in the repair information 163. When the control unit 15 stores the difference between the calculated predicted repair cost and the actual repair cost, the process ends. The control unit 15 may output the difference between the calculated predicted repair cost and the actual repair cost to the display unit 11.

  As shown in FIG. 4, the part repair work management device 10 predicts the degree of repair of parts of a maintenance target device (in this embodiment, a gas turbine), calculates a predicted repair cost based on the prediction, By outputting, it is possible to output a predicted repair cost (provisional repair cost). Further, the part repair work management apparatus 10 can estimate the repair contents without waiting for the result of the inspection by specifying the degree of repair from the operation information, and can output the predicted repair cost. Further, since the part repair work management apparatus 10 calculates the repair level based on the operation information and the repair evaluation parameters, the repair level can be automatically calculated. For this reason, the worker who performs the repair can present the provisional repair cost to the user of the apparatus before performing the inspection shown in FIG. That is, the worker who performs the repair uses the predicted value, but can perform the processing from step S10 to step S18 and the processing from step S18 to step S22 shown in FIG. 3 in parallel. Moreover, the parts repair work management apparatus 10 can also present the content of the repair implemented based on the repair degree with a temporary repair expense.

  As a result, the worker who performs the repair can use the parts repair work management apparatus 10 to start negotiations on the cost of repair and the content of the repair to the user of the apparatus earlier, before the inspection. It is possible to obtain an agreement on the construction contents during the inspection or immediately after the inspection is completed, and the repair work can be started earlier. Thereby, the parts moved from the place where the apparatus is installed for maintenance can be returned to the place where the apparatus is installed in a shorter time. By shortening the time to return the parts to the place where the equipment is installed, the spare parts that can be installed in the equipment can be shortened. The number can be reduced. In addition, even when parts need to be replaced due to unforeseen circumstances, it is possible to increase the possibility that parts can be replaced quickly.

  Further, by calculating the actual repair information and the actual repair cost and storing the difference from each predicted value, it is possible to grasp the error between the predicted value and the actual value. In this way, for example, when settlement is made with predicted repair costs and there is a deviation from actual repair costs, the difference is added to, subtracted from, and output the estimated repair costs for the next and subsequent times. Correction can be made, repair costs can be reliably recovered, and the exchange of money can be suppressed from becoming complicated.

  The part repair work management device 10 preferably performs various feedback processes based on the error between the predicted value and the actual value to increase the accuracy of the prediction.

  FIG. 5 is a flowchart showing a processing procedure of the part repair work management apparatus 10. FIG. 5 shows a processing procedure for correcting the repair evaluation parameter. The processing procedure shown in FIG. 5 is realized by the control unit 15 executing the component repair work management program 169. In step S50, the control unit 15 reads the difference between the calculated predicted repair cost and the actual repair cost. In step S52, the control unit 15 reads the calculated repair level and the actual repair content. That is, information on the degree of repair that has been predicted to calculate the predicted repair cost and the content of the repair that has been performed, which is the basis for calculating the actual repair cost, is acquired. When the control unit 15 acquires information on the repair level predicted in step S52 and the actual repair content, in step S54, the control unit 15 corrects the repair evaluation parameter based on the difference between the calculated repair level and the actual repair content. This process is terminated. The control unit 15 preferably corrects the repair evaluation parameter using the difference between the predicted repair cost calculated in step S50 and the actual repair cost in addition to the classification of the repair level.

  As shown in FIG. 5, the part repair work management device 10 can improve the accuracy of the repair evaluation parameter by correcting the repair evaluation parameter based on the comparison between the prediction result and the actual result. Thereby, the parts repair work management apparatus 10 can reduce the difference between the predicted repair level and the repair level specified based on the inspection. Moreover, the parts repair work management apparatus 10 can further reduce the difference between the predicted repair cost and the actual repair cost. Thus, the part repair work management apparatus 10 can increase the reliability of the predicted repair cost calculated by the part repair work management apparatus 10 by increasing the prediction accuracy. In addition, since the difference between the predicted repair cost and the actual repair cost is reduced, the worker who performs the repair can smoothly proceed with the negotiation based on the predicted repair cost.

  It is preferable that the component repair work management device 10 creates the repair evaluation parameters by classifying them for each model of the target device, for each type of component, and for each operation mode. Note that the same type of component means that the shape and function are the same, and the component can be installed by exchanging the position when installed in the apparatus. The parts repair work management device 10 classifies and creates the repair evaluation parameters for each model of the target device, for each type of component, and for each operation mode, thereby creating a model for each model of the device, and for each type of component of that model, A repair evaluation parameter suitable for the characteristic can be set for each operation mode. Thereby, the accuracy of calculation of the degree of repair can be further increased.
