It is to be understood that the data so used may be interchanged where appropriate in order to describe the embodiments of the application herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
According to an embodiment of the application, a method for determining failure risk of an event is provided.
Fig. 1 is a flowchart of a method for determining 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 a target event and a plurality of pieces 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 a process of the target event.
Specifically, the target event may be to produce an a product, where the a product needs to be produced using a production line, where each production line includes multiple processes, and each process may correspond to multiple failure mode information, for example, the a product may be a cup, where multiple failure modes may exist in a process of producing a cup lid, producing a cup body, producing a handle, coloring, and the like, for example, a cup lid cracking, a cup lid oversized, and the like.
It should be noted that, in the method for determining the failure risk of the event provided in this embodiment, the process template corresponding to the target event may be obtained first, where the process template includes all the process contents corresponding to the target event, for example, the process template corresponding to the product a may include the processes of producing the cup cover, producing the cup body, producing the handle, coloring, and the like, and meanwhile, multiple pieces of failure mode information corresponding to the target event may be obtained, for example, if the product a is a cup, relevant failure mode information about the cup cover, the cup body, the handle, and the color is obtained.
Step S104, matching the 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 corresponding to a target event and a plurality of failure mode information are obtained, each failure mode information and a process corresponding to the failure mode information are matched and connected to generate a target template corresponding to the target event, wherein the target template can be used for judging the failure risk of the target event. In each piece of failure mode information, failure reasons and failure index values of each failure mode are contained, for example, one failure mode corresponding to an A product is that a cup cover crack exceeds 1cm, the failure index value is 450, the cup cover is a bad product when the cup cover crack exceeds 1cm, namely the cup cover is failed, and in the case that the actual index value is greater than 450, the failure mode of the station is at failure risk, namely the bad product is at higher risk in terms of production, outflow and the like, and the failure mode of the station needs to be subjected to product design and corresponding improvement in product production, so that the failure risk is avoided.
Step S106, obtaining characteristic values corresponding to failure mode information matched by each procedure 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.
Specifically, the characteristic values corresponding to each failure mode of the target event in each process in actual production are obtained, wherein the characteristic values can include severity caused by failure occurrence, failure occurrence frequency and checked difficulty corresponding to failure phenomenon, namely detection degree. After the characteristic value is obtained, the characteristic value can be compared with the corresponding failure index value after being calculated, or the characteristic value can be compared with the corresponding failure index value, and the failure risk result corresponding to each process is obtained in different modes, so that the failure risk result corresponding to the target event is obtained.
For example, one failure mode corresponding to the product A is that the cup cover crack exceeds 1cm, the failure index value is 450, the severity of the cup cover crack exceeding 1cm is 7, the occurrence frequency is 4, the detection degree is 4, the characteristic index value is 112 through multiplication, and the characteristic index value is smaller than the failure index value 450, so that the current production mode and the inspection mode for the cup cover crack exceeding 1cm are proved to be normal.
The method for determining the failure risk of the event comprises the steps of obtaining a process template corresponding to a target event and a plurality of pieces of failure mode information corresponding to the target event, wherein the process template comprises process information required for completing the target event, the failure mode information is used for representing failure phenomenon information corresponding to a process of the target event, matching the plurality of pieces of failure mode information with the process information in the process template to obtain the target template, determining a failure index value corresponding to each piece of failure mode information, obtaining characteristic values corresponding to the failure mode information matched by each process in the target event, comparing each characteristic value with the failure index value corresponding to the failure mode information to obtain a plurality of comparison results, and determining the failure risk result of the target event according to the plurality of comparison results. The problem that failure risks in the production process of products cannot be obtained rapidly and accurately in the related technology is solved. The template is automatically matched with the failure mode to generate a risk judging template, and the failure risk is judged in a mode of automatically calculating and comparing the characteristic value to obtain a failure risk result, so that the failure risk result in the production process of the product is rapidly and accurately obtained, and the product design and production mode are modified.

Specifically, one or more keywords corresponding to the target event are input first, 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 to produce a cup, the keyword may be a cup including a cup cover and a handle, and then a process template corresponding to the process of producing the cup a may be obtained from a plurality of process templates in the first database, failure mode information corresponding to the process of producing the cup cover, producing the cup body, producing the handle and the like may be selected in the second database, failure mode information related to the cup cover in the failure mode information may be matched with the process of producing the cup cover in the process templates, and failure mode information related to the cup body in the failure mode information may be matched with the process of producing the cup body in the process templates, thereby obtaining the target template corresponding to the cup a.
Optionally, in the method for determining failure risk of an event provided by the embodiment of the application, each characteristic value comprises a plurality of sub-characteristic values, and comparing each characteristic value with a failure index value corresponding to failure mode information to obtain a plurality of comparison results, wherein the step of 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 piece of failure mode information is obtained, multiplication calculation can be performed on the sub-feature values in the feature values, a failure index value corresponding to each piece of failure mode information is obtained, and a calculation result is compared with the corresponding failure index value to obtain a comparison result, wherein the failure index value can be a preset RPN (Risk Priority Number risk coefficient value).
For example, one failure mode corresponding to the product A is that the cup body height is smaller than 50cm, the preset RPN is 300, the severity of the cup body height is smaller than 50cm in the actual production process is 8, the occurrence frequency is 2, the detection degree is 5, the characteristic index value is 80 through multiplication, and the result is normal if the characteristic index value is smaller than the preset RPN, and the current production mode and the inspection mode for the cup body height smaller than 50cm are proved to be free of risks.
Optionally, in the method for determining failure risk of an event provided by the embodiment of the application, determining the failure index value corresponding to each failure mode information includes obtaining all failure mode information in a target template, obtaining a preset template containing at least all failure mode information from a third database, obtaining a standard template, wherein the third database stores a plurality of preset templates, each preset template comprises preset procedure information, preset failure mode information and failure index values corresponding to each preset failure mode information, each failure index value comprises a plurality of sub-index values, obtaining failure index values corresponding to all failure mode information in the target template from the standard template, each characteristic value comprises a plurality of sub-characteristic values, comparing each characteristic value with the failure index value corresponding to the failure mode information, and obtaining a plurality of comparison results comprises determining the sub-index value of each sub-characteristic value in each characteristic value under the corresponding failure index value, comparing each sub-characteristic value with the corresponding sub-index value, obtaining a group of sub-comparison results, and determining the group of sub-comparison results as one comparison result.
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, for example, 20 failure mode information in the target template, is obtained in the third database, at this time, a search is performed in the third database, and an attempt is made to obtain a preset template, where the preset template includes 20 failure mode information in the target template, for example, 30 failure mode information in the preset template, and where 20 failure mode information is the same as 20 failure mode information in the target template.
After the preset template corresponding to the target template is obtained, an AP (Active 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 values 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 failure mode information corresponding to the target template, thereby obtaining a failure risk result corresponding to each failure mode information.
For example, one piece of preset failure mode information in the preset template is that the cup height is smaller than 50cm, the severity is 7, the occurrence frequency is 1, the detection degree is 6, the corresponding piece of preset failure mode information in the target template is that the cup height is smaller 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 larger than the sub-index value can be judged to be a risk failure mode, and the failure mode information is judged to be a risk failure mode because the severity and the frequency of the cup height being smaller than 50cm are both higher than the corresponding sub-index value in the preset template. After each piece of failure mode information in the target template is matched, combining a plurality of matching results to obtain a failure risk judgment result of the target event.
Optionally, in the method for determining failure risk of an event provided by the embodiment of the present application, in a process of acquiring all failure mode information in the target template and acquiring a preset template including at least all failure mode information from the third database, if the preset template including at least all failure mode information cannot be acquired, alarm information is generated.
Specifically, when the preset template is obtained from the third database, when the preset template corresponding to the target template cannot be obtained, alarm information, such as popup information, is sent out to inform a user that the preset template cannot be obtained, a plurality of sub-feature values in the target template can be automatically calculated in a product mode, and a calculation result is compared with a corresponding preset RPN to obtain a comparison result.
Optionally, in the method for determining failure risk of event provided by the embodiment of the application, after a plurality of pieces of failure mode information are matched with the pieces of process information in the process template to obtain the target template, the method further comprises the steps of judging whether a matching result of each piece of process information and the matched failure mode information is correct, under the condition that the matching result is incorrect, obtaining the target process information and the target failure mode information corresponding to the matching result, deleting the target failure mode information, re-obtaining the failure mode information from the second database according to the target process information, and adding the obtained failure mode information into the target template to obtain the updated target template.
Specifically, after each failure mode information and the corresponding procedure of the failure mode information are matched and connected to generate a target template corresponding to a target event, whether the target template is correct or not is checked, when partial procedures in the target template and the failure mode information are checked to be matched with errors, the failure mode information of the matched errors is deleted, and whether the second database has the failure mode information corresponding to the matching error procedure of the target event or not is checked, when the corresponding failure mode information is still present, the failure mode information is acquired and matched with the procedures, and when the corresponding failure mode information is not present, the generation of the target template is completed.
When the corresponding failure mode information does not exist, new failure mode information can be manually added into the third database, and the new failure mode information is matched with the process template to obtain the target template.
Optionally, in the method for determining the failure risk of the event provided by the embodiment of the application, after determining the failure risk result of the target event according to the plurality of comparison results, the method further comprises the steps of determining that the failure risk exists when the failure risk result indicates that the target event exists, acquiring correction characteristic values corresponding to the steps of correcting the steps of having the failure risk, comparing each correction characteristic value with the failure index value corresponding to the failure mode information to obtain a plurality of updated comparison results, and determining the failure risk result of the target event according to the plurality of updated comparison results.

And judging whether the corrected production mode has failure risk or not according to the corrected characteristic value in the target template.
