Problems solved by technology

[0009] ③[Reasonable] The cause of failure should be reasonable, regardless of extreme events (such as falling rocks on the road, power outage in the manufacturing plant, etc.)
Failures due to deliberate misuse (e.g. deliberate handling and sabotage) are not considered
[0010] ④ [Complete] No concealment of foreseeable potential failures should be made
[0016] In the above-mentioned risk assessment method, there is no problem with the understanding of the risk itself, but the problem lies in the assessment of how to take risk control measures or the priority of risk control measures.
The root cause of this problem is that the evaluation of the risk factors themselves and the evaluation of the risk control measures to be adopted are not clear. The existing evaluation methods confuse the above two problems into one problem, so they are confused and not well understood. Form a solution to this problem

Embodiment 1

[0041] Embodiment 1: Risk assessment of design FMEA, facility and equipment FMEA. The FMEA risk assessment form consists of three parts: risk assessment, risk control measure assessment, and comprehensive assessment of assessment results. The evaluation scoring criteria and the description of the corresponding situation in the evaluation form should be presented in a table to make it easy to understand. Of course, Quick Eat also has other auxiliary prompts to help understand the specific risk assessment process and assessment results.

[0042]Risk element assessment of design FMEA, facility and equipment FMEA mainly based on components and structural composition. ①Risk severity (S) assessment. Severity ratings are used to prioritize the scope of an FMEA and are determined without regard to frequency and detection. 10 means that it will cause death or serious injury to the relevant personnel. A score of 9 indicates that the requirements of a regulation are not met, and a sc...

Embodiment 2

[0045] Embodiment 2: Risk assessment of process FMEA. The FMEA risk assessment form consists of three parts: risk assessment, risk control measure assessment, and comprehensive assessment of assessment results. The evaluation scoring criteria and the description of the corresponding situation in the evaluation form should be presented in a table to make it easy to understand. Of course, Quick Eat also has other auxiliary prompts to help understand the specific risk assessment process and assessment results.

[0046] Risk element assessment of process FMEA. ①Risk severity (S) assessment. The severity assessment of process-related risk factors includes the impact on engineering, the impact of materials shipped to factories or the impact of products sent to distributors, and the impact of products on end users. The results of the assessment of the effects of failure shall be agreed between the customer and the organization. If the customer affected by the failure mode is the ...

Embodiment 3

[0049] Embodiment 3: Risk assessment of monitoring and feedback (FMEA-MSR). The FMEA risk assessment form consists of three parts: risk assessment, risk control measure assessment, and comprehensive assessment of assessment results. The evaluation scoring criteria and the description of the corresponding situation in the evaluation form should be presented in a table to make it easy to understand. Of course, Quick Eat also has other auxiliary prompts to help understand the specific risk assessment process and assessment results.

[0050] Risk element assessment for monitoring and feedback (FMEA-MSR). ①Risk severity (S) assessment. The severity of monitoring and feedback FMEA evaluation is similar to that of design FMEA and equipment FMEA, and the severity of its impact can be directly considered. ②Assessment of risk frequency (F). A measure of the likelihood of occurrence of a cause of failure in a monitoring or feedback related operation. If the cause of failure does not...

Abstract

The patent provides a reliable and stable risk assessment result for the improvement of the risk assessment of the FMEA method through the assessment of the severity, occurrence frequency, detection degree, risk control measures and cost and time factors of risk factors. Compared with existing FMEA method risk assessment, risk control measure assessment including risk control measure effect assessment, cost assessment and time assessment is added, and risk control measures which are high in severity, acceptable in control measure time and cost and definite in risk control effect are found, andkey prevention and control are carried out. The improved FMEA method risk assessment is suitable for design of FMEA (or equipment FMEA), technological process FMEA, monitoring and feedback FMEA assessment. The FMEA method risk assessment table can be designed and manufactured into a network database or a stand-alone database, can be designed into a table type table, and can also be a determinanttype risk assessment table.

Description

technical field [0001] This patent provides an improved FMEA risk assessment form. The FMEA risk assessment form of this patent can be designed and made into a network database or a stand-alone database. It can be designed as a tabular form or a determinant risk assessment form. . Background technique [0002] The product manufacturing industry is facing a variety of challenges with increasing customer quality requirements, cost-optimized products and processes, higher levels of complexity, and legal requirements for design providers and manufacturers to assume more product responsibility. Therefore, we adopt FMEA method to solve technical problems in order to reduce risks. Manufacturers consider many types of risk, including technical risk, financial risk, timing risk, and strategic risk. FMEA is only used to analyze technical risks, thereby reducing failures and improving product and process safety. [0003] Failure Mode and Effects Analysis is "Potential Failure Mode a...
