According to an embodiment of the application, a method of determining a risk of failure of an event is provided.
Fig. 1 is a flowchart of a method for determining a failure risk of an event according to an embodiment of the present application. As shown in fig. 1, the method comprises the steps of:
step S102, a process template corresponding to the target event and a plurality of failure mode information corresponding to the target event are obtained, wherein the process template comprises process information required for completing the target event, and the failure mode information is used for representing failure phenomenon information corresponding to the process of the target event.
Specifically, the target event may be production of a product a, where the product a needs to be produced by using a production line, each production line includes a plurality of processes, and each process may correspond to a plurality of failure mode information, for example, the product a may be a cup, and may include processes of producing a cup cover, producing a cup body, producing a handle, coloring, and the like, where a plurality of failure modes may exist in the process of producing the cup cover, for example, the cup cover is cracked, the cup cover is oversized, and the like.
It should be noted that the method for determining the failure risk of an event according to this embodiment may first obtain a process template corresponding to a target event, where the process template includes all process contents corresponding to the target event, for example, the process template corresponding to the product a may include processes of producing a cup lid, producing a cup body, producing a handle, coloring, and the like, and at the same time, may also obtain a plurality of failure mode information corresponding to the target event, for example, if the product a is a cup, obtain related failure mode information about the cup lid, the cup body, the handle, and the color.
And step S104, matching the plurality of failure mode information with the process information in the process template to obtain a target template, and determining a failure index value corresponding to each failure mode information.
Specifically, after a process template and a plurality of failure mode information corresponding to a target event are obtained, matching and connecting each failure mode information and a process corresponding to the failure mode information to generate a target template corresponding to the target event, wherein the target template can be used for judging failure risks of the target event. In each failure mode information, the failure cause and the failure index value of each failure mode are included, for example, one failure mode corresponding to the product a is: the cup cover cracks exceed 1cm, the failure index value is 450, which indicates that cracks exist on a certain cup cover, and when the cracks exceed 1cm, the cup cover is a defective product, namely, the cup cover is failed, and when the actual index value is greater than 450, the failure mode of the station has failure risk, namely, the defective product has higher risk in the aspects of production, outflow and the like, and corresponding improvement on product design and product production needs to be performed aiming at the failure mode of the station, so that the failure risk is avoided.
And step S106, acquiring characteristic values corresponding to failure mode information matched with each process in the target event, comparing each characteristic value with a failure index value corresponding to the failure mode information to obtain a plurality of comparison results, and determining a failure risk result of the target event according to the plurality of comparison results.

After the characteristic value is obtained, the characteristic value can be compared with a corresponding failure index value after being calculated, or the characteristic value can be compared with a corresponding failure index value, and a failure risk result corresponding to each process is obtained through different modes, so that a failure risk result corresponding to the target event is obtained.
For example, one failure mode for product a is: the cup cover crack is more than 1cm, the failure index value is 450, in the actual production process, the severity of the cup cover crack which is more than 1cm is 7, the occurrence frequency is 4, the detection degree is 4, the characteristic index value is 112 can be obtained in a multiplication mode, and the result is normal if the characteristic index value is less than 450, so that the current production mode and the inspection mode for the cup cover crack which is more than 1cm are proved to have no risk.
According to the method for determining the failure risk of the event, the process template corresponding to the target event is obtained, and the plurality of failure mode information corresponding to the target event are obtained, wherein the process template comprises the process information required for completing the target event, and the failure mode information is used for representing the failure phenomenon information corresponding to the process of the target event; matching the plurality of failure mode information with the process information in the process template to obtain a target template, and determining a failure index value corresponding to each failure mode information; and obtaining characteristic values corresponding to failure mode information matched with each process in the target event, comparing each characteristic value with a failure index value corresponding to the failure mode information to obtain a plurality of comparison results, and determining a failure risk result of the target event according to the plurality of comparison results. The problem of can't obtain the inefficacy risk in the product production process fast accurately among the correlation technique is solved. The template and the failure mode are automatically matched to generate a risk judgment template, failure risks are judged in a mode of automatically calculating and comparing the characteristic values, and a failure risk result is obtained, so that the failure risk result in the production process of the product can be quickly and accurately obtained, and the product design and the production mode can be rectified.

Specifically, one or more keywords corresponding to a target event are input, a process template corresponding to the keywords is obtained in a first database through the keywords, and all failure mode information corresponding to the keywords is obtained in a second database. For example, if the target event is a cup production a, the keyword may be a cup including a cup cover and a handle, a process template corresponding to the process of producing the cup production a may be obtained from a plurality of process templates in the first database, failure mode information corresponding to the processes of producing the cup cover, producing the cup body, producing the handle and the like may be selected from the second database, failure mode information related to the cup cover in the failure mode information may be matched with a process of producing the cup cover in the process template, failure mode information related to the cup body in the failure mode information may be matched with a process of producing the cup body in the process template, and thus a target template corresponding to the cup production a may be obtained.
Optionally, in the method for determining a failure risk of an event provided in the embodiment of the present application, each feature value includes a plurality of sub-feature values, and comparing each feature value with a failure index value corresponding to failure mode information to obtain a plurality of comparison results includes: and multiplying all the sub-characteristic values in the same characteristic value to obtain a target characteristic value, and comparing the target characteristic value with the failure index value corresponding to the characteristic value to obtain a comparison result.
Specifically, after the feature value corresponding to each failure mode information is obtained, multiplication calculation may be performed on sub-feature values in the feature values, a failure index value corresponding to each failure mode information is obtained, and the calculation result is compared with the corresponding failure index value to obtain a comparison result, where the failure index value may be a preset RPN (Risk Number coefficient value).
For example, one failure mode for product a is: the cup height is less than 50cm, the preset RPN is 300, in the actual production process, the severity of the cup height less than 50cm is 8, the occurrence frequency is 2, the detection degree is 5, the characteristic index value can be obtained in a multiplication mode to be 80, if the detection degree is less than the preset RPN, the current production mode and the inspection mode of the cup height less than 50cm are proved to have no risk, and the result is normal.

Specifically, after the target template is obtained, all failure mode information in the target template may be obtained, and a preset template including all failure mode information in the target template is obtained in the third database, for example, 20 failure mode information in the target template, and at this time, a search is performed in the third database to attempt to obtain a certain preset template, where the preset template includes 20 failure mode information in the target template, for example, the preset template includes 30 failure mode information, and where 20 failure mode information is the same as 20 failure mode information in the target template.
It should be noted that after the preset template corresponding to the target template is obtained, an AP (Active Priority initiative Priority) value in the preset template is obtained and compared with a feature value in the target template, where the preset template may be an AP data table, and the AP value may be a plurality of sub-index values in the failure index value corresponding to each preset failure mode information. And comparing each sub index value with the sub characteristic value in the characteristic value corresponding to the corresponding failure mode information in the target template, thereby obtaining a failure risk result corresponding to each failure mode information.
For example, one preset failure mode information in the preset template is: the cup height is less than 50cm, the severity is 7, the occurrence frequency is 1, the detection degree is 6, and the corresponding preset failure mode information in the target template is as follows: the height of the cup body is less than 50cm, the severity is 8, the occurrence frequency is 2, the detection degree is 4, the sub-characteristic value of the target template is compared with the corresponding sub-index value in the preset template, the failure mode information with the sub-characteristic value greater than the sub-index value can be judged as a risk failure mode, and the failure mode information is judged as a risk failure mode because the severity and the frequency of the height of the cup body less than 50cm are both higher than the corresponding sub-index value in the preset template.

Specifically, after matching and connecting each failure mode information with a process corresponding to the failure mode information to generate a target template corresponding to a target event, whether the target template is correct needs to be checked, when a matching error between a part of processes in the target template and the failure mode information is checked, the failure mode information with the matching error is deleted, whether the second database has failure mode information corresponding to the matching error process of the target event or not is determined, when the corresponding failure mode information exists, the failure mode information is acquired and matched with the processes, and when the corresponding failure mode information does not exist, the generation of the target template is completed.
It should be noted that, when there is no corresponding failure mode information, new failure mode information may be manually added to the third database, and the new failure mode information is matched with the process template to obtain the target template.
