Description

  The present invention relates to a parts management system, and more particularly, to a parts management system that manages maintenance timing such as replacement and inspection timing of parts constituting a device such as a computer device.

  Conventionally, during periodic inspections of computer devices, etc. used by users and companies, parts replacement and inspection cycle specification are the failure rates and components calculated at the time of development by the system development department of the above computer devices, etc. This is based on the life (MTBF). For example, a method is adopted in which the actual operating time of a component mounted on a computer device is compared with a preset threshold value representing a component life and it is determined that the component is to be replaced when the threshold value is exceeded. ing.

  However, devices such as computer devices differ in operating time and installation environment for each user to use. Also, depending on the operation time after replacement in parts replacement at the time of restoration work performed due to failure etc. or parts replacement performed in the improvement work aimed at improving product quality, it is better to replace it at this periodic inspection, There was a problem that it was not possible to determine whether it was a part that could be replaced at the next periodic inspection, and it was not possible to determine whether the inspection cycle was appropriate. In other words, the parts replacement and inspection cycle are presented based on information calculated at the time of development by the system development department, but the system operating time and installation environment for each user actually used is not reflected. . For this reason, parts that do not need to be replaced may be replaced, or periodic inspection may be performed in a shorter period than the presented cycle. Accordingly, there has been a problem that maintenance such as inspection and part replacement is not necessarily performed at an appropriate timing, and the cost consumed by inspection and part replacement increases.

  In order to solve the above-described problem, Patent Document 1 discloses a system in which a part is inspected and a replacement time is specified in consideration of a use state of a device such as a computer on which the part is mounted. Specifically, in this system, the parts replacement time is predicted using mining technology based on the installation environment for each apparatus, the past work situation, and the failure tendency.

At this time, by comparing the cumulative operation time and the estimated lifetime, the component information that is better exchanged with the periodic inspection for each computer device is output. In addition, it is judged whether it is better to carry out periodic inspections based on the output number of days for periodic inspections. When it is necessary to perform periodic inspection or replacement of parts, schedule of periodic inspection and information on replacement parts are transmitted to the mobile terminal 20 via the network (arrow Y11 in FIG. 15).

  Thereby, the maintenance worker who operates the mobile terminal 20 that has received the information proposes and executes a periodic inspection and replacement parts. Then, when a work such as periodic inspection or parts replacement is actually performed, information related to the work content is input from the portable terminal 20, and the same as in the case of the arrows Y1, Y2, Y3 shown in FIG. Then, the data in the user information management system 30 and the database in the operation quality management system 50 are updated (arrows Y12, Y13, Y14 in FIG. 15). Thereby, information at the time of parts replacement is further accumulated, and the accuracy of future mining is increased.

The component information management system 40 compares the system name and the system model number in the component database 43 from the received system name and system model number regarding the computer apparatus 10, and the component name configured from the matched system name and system model number. And information on the part number is output (step A7). Then, the part name and part number output from the component part database 43 are compared with the database in the part information database 44, and the part life (calculated at the time of development by the system development department regarding the matched part name and part number) MTBF) (H), periodic replacement interval (M), and information regarding parts information to be replaced by improvement work for the purpose of improving product quality are output and transmitted to the operation quality management system 50 (step A8, step B2 in FIG. 17). ).

  Thereafter, the operation quality management system 50 creates a data table 55 necessary for analyzing replacement parts related to the computer apparatus 10. The data table 55 uses the component parts of the computer apparatus 10 as keys, the part name and part number, the cumulative operating time and usage status and work history information, the part life (MTBF) (H), the periodic replacement interval (M), and the product. The component information to be replaced by the improvement work for the purpose of quality improvement is described (step A9, step B4 in FIG. 17). In addition, the operation quality management system 50 outputs information at the time of replacement indicating the situation at the time of replacement of all the same parts stored in the operation quality management database 54 from the information regarding the component parts of the computer apparatus 10 (step A10, Step B5 in FIG.

  Then, the operation quality management system 50 calculates the estimated lifetime of replacement parts related to the computer device 10 from the above information using a mining technique. The mining technique is a technique for analyzing a large amount of accumulated data, searching for a correlation pattern between items from the data, and outputting necessary information. As a method of using the mining technology in this system, there is a tool for calculating information on the estimated life time in which the replacement parts constituting the computer device 10 operate without causing a failure. , The actual accumulated operating time and usage status of the computer device 10, work days (improvement work and periodic inspections for the purpose of fault replacement and product quality improvement), fault trends, and the past of the same parts Based on the replacement status, an estimated life time analysis and failure analysis are performed for each replacement part used in the computer apparatus 10 (step A11, arrow Y8 in FIG. 15, step S6, B7 in FIG. 17).

  For example, if the cumulative operating time of a part is short and the usage status is low, it is determined that the installation environment is bad, and the estimated life time is calculated by subtracting a predetermined time from the life time set in advance. Calculate as Further, when there is a part that has been replaced in the past in the same operating time or usage situation, the estimated lifetime is calculated by increasing or decreasing the predetermined time in consideration of the actual lifetime. Further, the estimated lifetime is calculated by increasing or decreasing the predetermined time in consideration of the frequency of periodic inspections and the like. This calculation method is an example, and the estimated lifetime may be calculated by any method. Further, referring to past replacement examples of the same type of part, it is possible to determine a possible failure of the part that is the maintenance target, and to determine whether or not it should be replaced according to the result.

  Thereafter, the operation quality management system 50 calculates the operation time per day for the computer device 10 from the accumulated operation time, and identifies the periodic inspection date by dividing the estimated life time by the operation time per day (step A12). , Step B10 in FIG. Then, the operation quality management system 50 transmits the calculated periodic inspection date to the user information management system 30 via the network 100 (step A13, step B11 in FIG. 17). The user information management system 30 records the calculated periodic inspection date in the user information database 33 and ends (step A14).

  In addition, the operation quality management system 50 accumulates each replacement part from the date of the periodic inspection performed previously and the date of replacement of the part due to the improvement work for improving the quality of the fault or product to the date on which the periodic inspection is to be performed. Comparison between the scheduled periodic inspection date calculated from the operating time (steps B8 and B9 in FIG. 17) and the periodic inspection date calculated from the estimated lifetime for the replacement part configured by the computer device 10 using the mining technology. Implement (Step A15, arrow B12 in FIG. 17). That is, the cumulative operation time of the parts is compared with the estimated life time.

  At this time, if the scheduled periodic inspection date (cumulative operation time) is smaller than the calculated periodic inspection date (estimated lifetime) (Yes in step A15, No in step B13 in FIG. 17), it is necessary to carry out the scheduled periodic inspection date. The calculated periodic inspection information is transmitted to the mobile terminal 20 via the network 100, and the process proceeds to step A16 (step B15 in FIG. 17). Then, the operation quality management system 50 transmits only the calculated periodic inspection date information to the mobile terminal 20 via the network 100 (step A16, step B15 in FIG. 17). Then, the portable terminal 20 displays the periodic inspection information (for example, refer to FIG. 12) received from the operation quality system management system 50 via the network 100, and ends (Step A15). Thereby, the maintenance staff grasps the scheduled periodic inspection.

  On the other hand, if the scheduled periodic inspection date is greater than the calculated periodic inspection date (No in step A15, Yes in step B13 in FIG. 17), it is determined that the parts need to be replaced, and step A17 (step in FIG. 17). Go to B14). Then, the operation quality management system 50 transmits the calculated periodic inspection date and replacement part information to the mobile terminal 20 via the network 100 (step A17, step B16 in FIG. 17). Then, the portable terminal 20 displays the periodic inspection information and replacement part information (for example, see FIG. 13) received from the operation quality system management system 50 via the network 100 (step A18), and the maintenance staff performs the periodic inspection. And parts replacement work is performed (step A19).

  Thereafter, the maintenance staff transmits the work content from the portable terminal 20 to the user information management system 30 via the network 100 after carrying out the periodic inspection and the parts replacement (step A20). The user information management system 30 updates the work content received from the mobile terminal 20 via the network 100 to the work history information database 34 (step A21). Further, the user information management system 30 transmits the update data to the operation quality management system 50 via the network 100 after the database update of the work history information database 34 (step A22). Then, the operation quality management system 50 adds the data regarding the reason for component replacement, the accumulated operation time, and the usage status received from the user information management system 30 via the network 100, and updates the operation quality management database 54 (step A23). . Note that the mobile terminal 20 may directly transmit the reason for component replacement to the operation quality management system 50 and register it in the operation quality management database 54.

  As a result, by adding information to the operating quality specifying database and increasing the number of stored information, it is possible to improve the calculation accuracy of the estimated lifetime of replacement parts related to the computer device 10.

  As described above, according to the present embodiment, the operation status and work status of the part, the replacement status of other identical parts, and the development department have been set in advance for the part to be maintained. Based on the lifetime, specify the parts maintenance time. As described above, since the maintenance timing is calculated based on a large amount of information for each component, it is possible to calculate a more appropriate maintenance timing in consideration of the situation for each component. As a result, useless inspection and parts replacement can be suppressed, the reliability of the apparatus can be improved, and the part cost can be reduced. In particular, by calculating an estimated lifetime, a failure tendency, and the like, it is possible to calculate a more clear maintenance timing such as an inspection time or a parts replacement time. Further, by accumulating and increasing information indicating the replacement status of replacement parts, it is possible to improve periodic inspection and the accuracy of specifying replacement parts.

  Here, the operation quality management system 50 has exemplified the case where the estimated life time of the component is calculated. However, the operation quality management system 50 is not limited to the calculation, and represents the maintenance timing of the component to notify the maintenance staff and the user. It is configured to calculate information.

  In the above, the operation time and usage status of the parts subject to maintenance, the reason for replacement of the same parts, the operation time until the replacement, etc., and the lifetime of the preset parts, etc. Although it is configured to calculate the estimated lifetime, etc., the information to be referred to is not limited to these. For example, the estimated lifetime etc. may be calculated without referring to the preset lifetime of the parts, and at least the operating status and working status for each component to be maintained, and also the replacement status of the same component The estimated lifetime is calculated based on the information to be expressed.
