[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Figure 1 This is a flowchart illustrating a PFMEA-based MFMEA information visualization method according to the present invention. The PFMEA-based MFMEA information visualization method includes:

[0040] Step 101: Construct the following libraries: equipment function library, equipment characteristic library, equipment element library, equipment element function library, equipment element characteristic library, equipment failure mode library, equipment failure consequence library, equipment failure cause library, maintenance prevention measure library, maintenance detection measure library, and maintenance response measure library.

[0041] Step 102: Create a new MFMEA project. The MFMEA project includes the product number, name, and task time of the product to be designed.

[0042] Step 103: Call the equipment element library to construct the equipment structure tree of the product to be designed.

[0043] Each node in the device structure tree represents a combination of multiple devices that make up the product to be designed. Each device in a higher-level node includes the devices in the corresponding lower-level nodes.

[0044] Step 104: Call the equipment function library, the equipment characteristic library, the equipment element function library, the equipment element characteristic library, and the equipment element functions and equipment element characteristics of the PFMEA of the product to be designed, add equipment functions or equipment features to each node in the equipment structure tree, and output the equipment structure function tree.

[0045] Step 105: Call the device failure mode library, the device failure consequence library, and the device failure cause library to add device failure modes to each node on the device structure function tree and output the device function failure tree.

[0046] Specifically, step 105 includes: calling the device failure mode library, the device failure consequence library, and the device failure cause library to add device failure modes, device failure consequences, and device failure causes to each node on the device structure function tree, and outputting the device function failure tree.

[0047] Device Failure Tree Figure 2 As shown, Figure 2 In the middle section, FM represents the device failure mode, and FC represents the device failure consequence.

[0048] Step 106: For each failure mode identified from the equipment functional failure tree, output the equipment risk list by calling the maintenance prevention measure library, maintenance detection measure library, and maintenance response measure library.

[0049] Step 107: Based on the equipment risk list, call the maintenance prevention measures library, maintenance detection measures library, and maintenance response measures library to optimize the measures to be taken for the corresponding failure models, and output the equipment optimization measures table.

[0050] The equipment optimization measures table includes equipment elements, equipment failure modes, equipment failure causes, equipment failure consequences, optimized maintenance prevention measures, optimized maintenance detection measures, and optimized maintenance response measures.

[0051] Each optimization measure is assigned to a specific person in charge and a deadline for that person.

[0052] A PFMEA-based method for visualizing MFMEA information also includes:

[0053] Output an MFMEA report based on the equipment functional failure tree, equipment risk list, and equipment optimization action table. The MFMEA report document is as follows: Figure 3 As shown.

[0054] The equipment risk list corresponds one-to-one with each node in the equipment functional failure tree.

[0055] The equipment risk list includes the equipment name, equipment function, equipment failure mode, equipment failure cause, equipment failure consequences, and measures taken to address the equipment failure mode.

[0056] The following details a method for visualizing MFMEA information based on PFMEA according to the present invention.

[0057] This invention proposes a PFMEA-based MFMEA information visualization method through a software system.

[0058] Step 1: After logging into the system, open the system's knowledge base module and add relevant knowledge descriptions for the 10 sub-module knowledge bases required to support MFMEA analysis. The 10 sub-module knowledge bases are: Equipment Function Library, Equipment Characteristic Library, Equipment Element Library, Equipment Element Function Library, Equipment Element Characteristic Library, Equipment Failure Mode Library, Equipment Failure Consequence Library, Equipment Failure Cause Library, Maintenance Prevention Measures Library, Maintenance Detection Measures Library, and Maintenance Response Measures Library.

[0059] Step 2: After completing Step 1, switch to the MFMEA module and fill in the relevant information according to the requirements of the new form in this module to successfully create an MFMEA project. After opening this new project, you will enter the MFMEA structure tree module.

[0060] Step 3: Based on the structure tree module opened in Step 2, the person in charge and their team members can right-click to call up the contents of the equipment element library module in Step 1 to complete the structure building of the equipment of the current MFMEA analysis object and output the equipment structure tree.

[0061] Step 4: Based on the equipment structure tree content output in Step 3, switch to the process requirements module of the current MFMEA, and in the process requirements module, query the equipment code by condition and first import the equipment function or characteristic content and its corresponding failure content from the corresponding PFMEA library module, and output the equipment structure function tree.

[0062] Step 5: Based on the device function tree completed in Step 4, you can continue to identify device function failure modes and associated failure consequences and failure causes by right-clicking on the device function tree nodes and calling the device failure mode library, device failure consequence library, and device failure cause library from Step 1, and output the device function failure tree.

[0063] Step 6: Based on the equipment functional failure tree completed in Step 5, the identified failure causes are analyzed by right-clicking and calling the maintenance prevention measures library, maintenance detection measures library, and maintenance response measures library from Step 1 to complete the equipment failure risk analysis and output the equipment risk list table.

[0064] Step 7: Based on the equipment risk list output in Step 6, determine the risks that need to be optimized and reduced. For the failure causes that need to be optimized and reduced, right-click to call up the maintenance prevention measures library, maintenance detection measures library, and maintenance response measures library in Step 1 to complete the optimization measures analysis. Assign each optimization measure to a specific person and deadline, and output the equipment optimization measures table.

[0065] Step 8: Based on all the operations in Steps 2 to 7, finally output the MFMEA report file content that meets the process design requirements.

[0066] This invention transmits the equipment requirements identified during the process design to specialized equipment structure and maintenance designers through a system. It also refines and visualizes the equipment functions required by the process, considers equipment design from the perspective of actual production requirements, comprehensively analyzes equipment risks, and outputs equipment maintenance plans that better meet actual process production requirements, thereby improving equipment stability and reliability. At the same time, it can also save the company's equipment maintenance costs, thereby increasing the company's production revenue.
