[0056] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0057] With the rapid development of modern industry, the complexity of contemporary equipment such as aircraft, ships, and large machinery is constantly increasing, and the importance of maintainability design and maintenance management is also growing. Therefore, in order to better evaluate maintenance efficiency during the maintenance process, evaluation methods for maintenance efficiency have emerged. Existing maintenance efficiency evaluation methods generally involve conducting protective design based on equipment structure simulation, and then evaluating maintenance efficiency based on this protective design.

[0058] However, using existing maintenance efficiency evaluation methods to evaluate maintenance efficiency solely from the perspective of overall protection design will reduce the reliability of maintenance efficiency evaluation.

[0059] Based on this, in an exemplary embodiment, a method for evaluating maintenance efficiency is provided. The method is illustrated using an application to a server as an example. Figure 1 As shown, the specific steps include:

[0060] S101, in response to a maintenance efficiency evaluation request for the target equipment, determines each field replaceable unit in the target equipment, as well as the maintenance steps and operation and maintenance configuration information for each field replaceable unit.

[0061] The target equipment refers to equipment that requires maintenance efficiency evaluation; maintenance efficiency refers to the efficiency of maintenance work, a comprehensive concept that measures the input-output ratio or resource utilization effect of maintenance activities (including maintenance, upkeep, and repair). Furthermore, a maintenance efficiency evaluation request is a request to evaluate the efficiency of maintenance work.

[0062] The term "Line Replaceable Unit" (LRU) refers to a modular component in the equipment that can be quickly disassembled and replaced; "maintenance procedure" refers to the specific steps required to replace or repair an LRU; and "maintenance configuration information" refers to the document information on which equipment maintenance is based, such as, but not limited to, the equipment maintenance manual.

[0063] Optionally, upon detecting a maintenance efficiency evaluation request for the target equipment issued by the maintenance provider, the equipment structure information of the target equipment can be retrieved based on the equipment identifier; subsequently, the replaceable units within the target equipment can be obtained from the equipment structure information. Here, the maintenance provider can be maintenance personnel.

[0064] Furthermore, for each field replaceable unit, the maintenance steps for the field replaceable unit can be determined based on its installation status in the target device, and the operation and maintenance configuration information of the field replaceable unit can be obtained from the maintenance files associated with the target device.

[0065] For example, the maintenance steps of the LRU can be presented in tabular form. Table 1 is a list of LRU maintenance steps.

[0066] Table 1 LRU Maintenance Procedures List

[0067]

[0068] S102, for each field replaceable unit, based on the operation and maintenance configuration information of the field replaceable unit, determine the maintenance evaluation value of the maintenance steps of the field replaceable unit under the preset dimension.

[0069] The preset dimensions include at least one of the following: workload analysis, safety analysis, accessibility analysis, activity space analysis, and visibility analysis. Specifically, workload analysis examines whether maintenance personnel, under specific operating space and posture, can provide sufficient strength to continuously complete the prescribed tasks; safety analysis primarily analyzes the impact of high pressure, high temperature, corrosion, and radiation on the health and safety of maintenance personnel, and should also include the safety analysis of the equipment; accessibility analysis primarily analyzes whether maintenance personnel can reach test points, repair points, and operating points, including both manual and tool-based operations; activity space analysis primarily analyzes whether the equipment provides sufficient and continuous operating and movement space for maintenance personnel and disassembled parts; and visibility analysis primarily analyzes whether maintenance personnel can see the workpiece during maintenance operations and whether sufficient lighting conditions are provided.

[0070] The so-called maintenance evaluation value is the numerical value used to evaluate the efficiency of standard maintenance work.

[0071] Optionally, for each field replaceable unit, the maintenance steps of the field replaceable unit can be analyzed under pre-selected preset dimensions based on the operation and maintenance configuration information of the field replaceable unit to obtain the maintenance evaluation value of the maintenance steps of the field replaceable unit.

[0072] For example, the operation and maintenance configuration information and maintenance steps of the field replaceable unit can be input into a trained evaluation model, and the evaluation model can output the maintenance evaluation value corresponding to the maintenance steps of the field replaceable unit based on the operation and maintenance configuration information, maintenance steps and model parameters.

[0073] It is worth noting that preset dimensions can be adaptively adjusted according to the specificity of the replaceable unit. For example, for maintenance work involving the disassembly and assembly of mechanical parts in a separate dedicated room, if the replacement process does not involve the handling of heavy objects and the maintenance process is relatively simple, then safety analysis is not required.

[0074] S103. Based on the maintenance evaluation values ​​of each replaceable unit at the site, determine the maintenance efficiency evaluation value of the target equipment.

[0075] Among them, the so-called maintenance efficiency evaluation value is used to characterize the numerical value that can evaluate the efficiency of the target equipment when it is being maintained.

[0076] Optionally, with only one preset dimension, after calculating the maintenance evaluation value of each field replaceable unit, the maintenance evaluation value of each field replaceable unit can be directly analyzed to obtain the maintenance efficiency evaluation value of the target equipment. For example, the maintenance evaluation value of each field replaceable unit can be input into a trained analysis model, which will then output the maintenance efficiency evaluation value of the target equipment based on the maintenance evaluation value of each field replaceable unit and the model parameters.

[0077] When multiple preset dimensions exist, after analyzing the maintenance efficiency evaluation value of the target equipment under each preset dimension, the final maintenance efficiency evaluation value of the target equipment can be obtained by weighting the maintenance efficiency evaluation values ​​of the target equipment under each preset dimension.

[0078] For example, if there are 5 preset dimensions, the following formula (1) can be used to weight the maintenance efficiency evaluation value of the target equipment under each preset dimension to obtain the overall maintenance efficiency evaluation value of the target equipment.

[0079] (1)

[0080] Among them, f1, f2, f3, f4, and f5 are the weights corresponding to each preset dimension, which can be determined by expert scoring; G1, G2, G3, G4, and G5 are the maintenance efficiency evaluation values ​​under each preset dimension; and G is the overall maintenance efficiency evaluation value of the target equipment.

[0081] Optionally, after calculating the maintenance efficiency evaluation value, the efficiency evaluation result of the target equipment can be determined by comparing the maintenance efficiency evaluation value with a preset evaluation threshold. For example, the preset evaluation threshold can be set to 2, where the score range is 0 to 4. If G≥2, the efficiency evaluation result of the target equipment is determined to be passed; if G<2, the efficiency evaluation result of the target equipment is determined to be failed.

[0082] In the aforementioned method for evaluating maintenance efficiency, in response to a request for evaluation of maintenance efficiency for the target equipment, each field replaceable unit in the target equipment, as well as the maintenance steps and operation and maintenance configuration information of each field replaceable unit, are determined. For each field replaceable unit, based on the operation and maintenance configuration information, the maintenance evaluation value of the maintenance steps of the field replaceable unit is determined under preset dimensions. The preset dimensions include at least one of the following: workload analysis dimension, safety analysis dimension, accessibility analysis dimension, activity space analysis dimension, and visibility analysis dimension. Then, based on the maintenance evaluation value of each field replaceable unit, the maintenance efficiency evaluation value of the target equipment is determined. This method allows for a more detailed analysis of the maintenance efficiency evaluation for each maintenance step, ensuring the reliability of the maintenance efficiency evaluation.

[0083] Based on the above embodiments, in this application embodiment, when the preset dimension includes a workload analysis dimension, an optional method for determining the maintenance evaluation value is provided, such as... Figure 2 As shown, the specific steps include:

[0084] S201: Obtain the human maintenance resource information corresponding to the field replaceable unit under the maintenance step from the operation and maintenance configuration information of the field replaceable unit, and determine the first labor intensity corresponding to the maintenance step based on the human maintenance resource information.

[0085] Among them, the so-called human maintenance resource information refers to the maintenance party information associated with the maintenance steps of the replaceable unit on site; the so-called first labor intensity refers to the maintenance party's labor intensity analyzed based on the human maintenance resource information.

[0086] Optionally, the maintenance steps can be used as an index to retrieve the corresponding human maintenance resource information for the field replaceable units under the maintenance steps. Then, based on information such as labor time rate, average energy metabolism rate, physical labor mode, and net working time per workday in the human maintenance resource information, the labor intensity value corresponding to the maintenance steps can be calculated.

[0087] For example, refer to the formula I=10×R t ·BMR·S·W, where I is the first labor intensity; R tThe percentage of working hours is 1%. BMR is the basal metabolic rate, reflecting the level of basal metabolism. It refers to the energy expenditure per kilogram of body weight (or per square meter of body surface area) per hour when the body is in a basal metabolic state. Common units are kJ / (kg·h) or kcal / (kg·h), kJ / (m2·h) or kcal / (m2·h). S is the gender coefficient: male = 1, female = 1.3; W is the physical labor mode coefficient: lifting = 1, carrying = 0.4, pushing / pulling = 0.05.

[0088] Labor time rate R t The calculation method can be referred to the following formula (2). Wherein, Net working hours during the workday, in minutes; T k T represents the time spent on a single task, in minutes; T represents the total time spent on a workday, in minutes.

[0089] (2)

[0090] For example, the basal metabolic rate (BMR) can be calculated using any basal energy consumption equation. Here, the Harris-Benedict equation can be used as an example. When the repairman is female, BMR (kcal) = 655.1 + 9.56 × weight (kg) + 1.85 × height (cm) - 4.67 × age (years); when the repairman is male, BMR (kcal) = 66.47 + 13.75 × weight (kg) + 5.0 × height (cm) - 6.76 × age (years).

[0091] Furthermore, after calculating the labor intensity value, the first labor intensity corresponding to the maintenance step can be determined based on the correspondence between each candidate labor intensity value and each candidate first labor intensity.

[0092] For example, the correspondence between each candidate labor intensity value and each candidate first labor intensity can be presented in a table. Table 2 is the first labor intensity scoring table.

[0093] Table 2 First Labor Intensity Scoring Table

[0094]

[0095] S202, obtain the heart rate information of the maintenance party when actually performing maintenance steps, and determine the second labor intensity corresponding to the maintenance steps based on the heart rate information.

[0096] Among them, the so-called heart rate information refers to the instantaneous heart rate of the maintenance personnel during maintenance; the so-called second labor intensity represents the degree of fatigue of the maintenance personnel during actual maintenance.

[0097] Optionally, the heart rate sensor can be fixed to the maintenance personnel, and their instantaneous heart rate can be simultaneously monitored during the actual maintenance procedures. Then, based on the frequency of the instantaneous heart rate, the second workload corresponding to the maintenance procedure can be determined.

[0098] For example, if the maximum heart rate does not exceed 120 beats / min when performing the maintenance step, the second labor intensity is determined to be 2, which indicates that the test is qualified; if the above condition is not met, the second labor intensity is determined to be 0, which indicates that the test is unqualified.

[0099] S203, based on the first labor intensity and the second labor intensity, determine the maintenance evaluation value of the maintenance steps of the field replaceable unit under the work intensity analysis dimension.

[0100] Optionally, after determining the first labor intensity and the second labor intensity, the maintenance evaluation value of the maintenance steps of the field replaceable unit under the work intensity analysis dimension can be selected from the first labor intensity and the second labor intensity based on the magnitude of the second labor intensity.

[0101] For example, when multiple LRUs exist simultaneously, and each LRU corresponds to multiple maintenance steps, the first labor intensity E of the j-th maintenance step in the i-th LRU can be calculated by referring to step S201 above. 1ij Then, referring to the following formula (3), the first labor intensity E1 of the target equipment as a whole is calculated. Where, n is the number of LRUs; m is the total number of steps data corresponding to each LRU; mi is the total number of steps data in the i-th LRU.

[0102] (3)

[0103] Furthermore, referring to step S202 above, the second labor intensity F of the j-th maintenance step in the i-th LRU can be calculated. 1ij Then, referring to the following formula (4), the second labor intensity F1 of the target equipment as a whole is calculated.

[0104] (4)

[0105] Then, when F1=2, G1=E1; when 0≤F1<2, G1=F1. Here, G1 is the overall maintenance evaluation value of the target equipment under the working intensity analysis dimension.

[0106] In this embodiment of the application, by determining the first labor intensity based on human maintenance resource information and the second labor intensity based on heart rate information, the maintenance evaluation value of the maintenance steps of the field replaceable unit under the work intensity analysis dimension can be calculated, thus ensuring the reliability of the maintenance evaluation value calculation.

[0107] Based on the above embodiments, in this application embodiment, when the preset dimensions include a safety analysis dimension, an optional method for determining the maintenance evaluation value is provided, such as... Figure 3 As shown, the specific steps include:

[0108] S301 obtains the hazardous conditions that exist when performing maintenance procedures from the maintenance configuration information of the field replaceable unit, and determines the first safety score corresponding to the maintenance procedure based on the protection measures for the hazardous conditions.

[0109] The hazardous conditions present during maintenance procedures may include, but are not limited to, electrical or mechanical safety hazards such as high voltage, high temperature, corrosion, and radiation. The so-called first safety score is used to characterize the safety of maintenance protection.

[0110] Optionally, the maintenance configuration information of the replaceable unit on-site can be used to query for potential hazards during maintenance procedures. Then, based on whether protective measures are in place for these hazards during the maintenance procedure, a first safety score is determined for each procedure.

[0111] For example, if the hazard exists and corresponding protective design has been implemented, the first safety score is determined to be 2, indicating that the test is qualified; if the above conditions are not met, the first safety score is determined to be 0, indicating that the test is unqualified.

[0112] S302. Based on the actual number of times hazardous situations occur when the maintenance party actually performs maintenance procedures, determine the second safety score corresponding to the maintenance procedure.

[0113] The "actual occurrence count" refers to the actual number of times a hazardous situation occurs. The "second safety score" is used to characterize the level of safety regarding hazardous situations in actual operation and maintenance scenarios.

[0114] Optionally, a second safety score can be calculated based on the actual number of times each hazardous situation occurs during the actual execution of the maintenance steps by the maintenance party.

[0115] For example, safety issues such as high pressure, high temperature, corrosion, and radiation that occur when each LRU is carried out for maintenance can be recorded. If no such issues occur, the safety of that maintenance step for that LRU is qualified, i.e., the second safety score is 2. If the above conditions are not met, it is unqualified, i.e., the second safety score is 0.

[0116] S303, based on the first safety score and the second safety score, determine the maintenance evaluation value of the maintenance steps for field replaceable units under the safety analysis dimension.

[0117] Optionally, after determining the first safety score and the second safety score, the maintenance evaluation value of the maintenance steps of the field replaceable unit under the workload analysis dimension can be selected from the first safety score and the second safety score based on the magnitude of the second safety score.

[0118] For example, when multiple LRUs exist simultaneously, and each LRU corresponds to multiple maintenance steps, the first safety score E of the j-th maintenance step in the i-th LRU can be calculated by referring to step S301 above. 2ij Then, refer to the following formula (5) to calculate the first labor intensity E2 of the target equipment as a whole.

[0119] (5)

[0120] Furthermore, referring to step S302 above, the second safety score F for the j-th maintenance step in the i-th LRU can be calculated. 2ij Then, referring to the following formula (6), the second safety score F2 of the target equipment as a whole is calculated.

[0121] (6)

[0122] Then, when F2=2, G2=E2; when 0≤F2<2, G2=F2. Here, G2 is the overall maintenance evaluation value of the target equipment under the safety analysis dimension.

[0123] In this embodiment of the application, a first safety score is determined based on the protection against dangerous situations, and a second safety score is determined based on the actual number of times dangerous situations occur when the maintenance party actually performs maintenance steps. This allows for the calculation of the maintenance evaluation value of the field replaceable unit under the safety analysis dimension, ensuring the reliability of the maintenance evaluation value calculation.

[0124] Based on the above embodiments, in this application embodiment, when the preset dimension includes an accessibility analysis dimension, an optional method for determining the maintenance evaluation value is provided, such as... Figure 4 As shown, the specific steps include:

[0125] S401: Determine the unit deployment location associated with the maintenance step from the maintenance configuration information of the replaceable unit on site, and determine the first maintenance convenience score when the maintenance party performs the maintenance step based on the unit deployment location.

[0126] The so-called unit deployment location refers to the deployment location of the field replaceable unit associated with the maintenance procedure; the so-called first maintenance convenience score is used to characterize the ease of performing maintenance procedures for the field replaceable unit.

[0127] Optionally, the maintenance steps can be used as an index to search the maintenance configuration information of the field replaceable units to obtain the unit deployment locations of each field replaceable unit associated with the maintenance steps. Then, based on the accessibility of the unit deployment locations, a first maintenance convenience score can be determined for the maintenance team when performing the maintenance steps.

[0128] For example, the accessibility of the unit deployment location can be evaluated by referring to Table 3 below. Table 3 is the maintenance accessibility evaluation table. The score in Table 3 is the first maintenance accessibility score.

[0129] Table 3 Maintenance Accessibility Evaluation Table

[0130]

[0131] S402. The second maintenance convenience score is determined based on the equipment disassembly situation when the maintenance party actually performs maintenance procedures.

[0132] Among them, the so-called equipment disassembly situation refers to the disassembly of the equipment when the maintenance steps are actually performed; the so-called second maintenance convenience score is used to characterize the actual convenience of performing maintenance steps for replaceable units on site.

[0133] Optionally, a second maintenance convenience score can be determined based on the specific information of the relevant units that need to be disassembled when the maintenance party actually performs the maintenance steps. For example, Table 3 above can be used to evaluate the convenience of actual equipment disassembly.

[0134] S403. Based on the first maintenance convenience score and the second maintenance convenience score, determine the maintenance evaluation value of the maintenance steps of the field replaceable unit under the accessibility analysis dimension.

[0135] Optionally, a score can be selected from the first maintenance convenience score and the second maintenance convenience score as the maintenance evaluation value of the maintenance steps of the field replaceable unit under the accessibility analysis dimension. For example, the smaller score between the first maintenance convenience score and the second maintenance convenience score can be directly used as the maintenance evaluation value of the maintenance steps of the field replaceable unit under the accessibility analysis dimension.

[0136] For example, when multiple LRUs exist simultaneously, and each LRU corresponds to multiple maintenance steps, the first maintenance convenience score E for the j-th maintenance step in the i-th LRU can be calculated by referring to step S401 above. 3ij Then, refer to the following formula (7) to calculate the first maintenance convenience score E3 of the target equipment as a whole.

[0137] (7)

[0138] Furthermore, referring to step S402 above, the second maintenance convenience score F for the j-th maintenance step in the i-th LRU can be calculated. 3ij Then, refer to the following formula (8) to calculate the overall second maintenance convenience score F3 of the target equipment.

[0139] (8)

[0140] Then, G3 can be determined by referring to the formula G3=min{E3,F3}. Here, G3 is the overall maintenance evaluation value of the target equipment under the reachability analysis dimension.

[0141] In this embodiment, a first maintenance convenience score is determined by the unit deployment location, and a second maintenance convenience score is determined based on the equipment disassembly situation when the maintenance party actually performs maintenance steps. This allows for the calculation of the maintenance evaluation value of the maintenance steps for replaceable units on-site under the accessibility analysis dimension, ensuring the reliability of the maintenance evaluation value calculation.

[0142] Based on the above embodiments, in this application embodiment, when the preset dimension includes the activity space analysis dimension, an optional method for determining the maintenance evaluation value is provided, such as... Figure 5 As shown, the specific steps include:

[0143] S501 determines the standard maintenance space for the maintenance party to perform maintenance steps from the maintenance configuration information of the replaceable unit on site, and determines the first space score corresponding to the maintenance step based on the space area of ​​the standard maintenance space.

[0144] The so-called standard operation and maintenance space refers to the standardized operating space required to perform maintenance procedures; the so-called first space score is used to characterize the rationality of the standard operation and maintenance space corresponding to the performance of maintenance procedures.

[0145] Optionally, the maintenance steps can be used as an index to search the maintenance configuration information of the replaceable units in the field to obtain the standard maintenance space associated with the maintenance steps. Then, a space evaluation table can be consulted to determine the first space score corresponding to the maintenance step based on the area of ​​the standard maintenance space.

[0146] For example, the evaluation criteria for the maintenance space can be referenced in Table 4 below. Table 4 is the evaluation table for maintenance operation space. The score in Table 4 is the first space score.

[0147] Table 4 Evaluation Table of Maintenance Operation Space

[0148]

[0149] S502, determine the second space score corresponding to the maintenance step based on the actual operating space area when the maintenance party performs the maintenance step.

[0150] The so-called operating space area refers to the space area when the maintenance steps are actually performed; the so-called second space score is used to characterize the rationality of the actual operation and maintenance space when the maintenance steps are actually performed.

[0151] Optionally, a second space score can be determined based on the reasonableness of the operating space area when the maintenance party actually performs the maintenance steps. For example, Table 4 above can be used to evaluate the reasonableness of the actual operating space area.

[0152] S503, based on the first space score and the second space score, determine the maintenance evaluation value of the maintenance steps of the field replaceable unit under the activity space analysis dimension.

[0153] Optionally, a score can be selected from the first spatial score and the second spatial score as the maintenance evaluation value of the field replaceable unit maintenance steps under the activity space analysis dimension. For example, the smaller score between the first spatial score and the second spatial score can be directly used as the maintenance evaluation value of the field replaceable unit maintenance steps under the activity space analysis dimension.

[0154] For example, when multiple LRUs exist simultaneously, and each LRU corresponds to multiple maintenance steps, the first spatial score E of the j-th maintenance step in the i-th LRU can be calculated by referring to step S501 above. 4ij Then, refer to the following formula (9) to calculate the first spatial score E4 of the target equipment as a whole.

[0155] (9)

[0156] Furthermore, referring to step S502 above, the second spatial score F of the j-th maintenance step in the i-th LRU can be calculated. 4ij Then, referring to the following formula (10), the second space score F4 of the target device as a whole is calculated.

[0157] (10)

[0158] Then, G4 can be determined by referring to the formula G4=min{E4,F4}. Here, G4 is the overall maintenance evaluation value of the target equipment under the activity space analysis dimension.

[0159] In this embodiment of the application, a first space score is determined based on the area of ​​the standard operation and maintenance space, and a second space score is determined based on the area of ​​the operation space when the operation and maintenance party actually performs the maintenance steps. This allows for the calculation of the maintenance evaluation value of the field replaceable unit under the activity space analysis dimension, ensuring the reliability of the maintenance evaluation value calculation.

[0160] Based on the above embodiments, in this application embodiment, when the preset dimensions include a visibility analysis dimension, an optional method for determining the maintenance evaluation value is provided, such as... Figure 6 As shown, the specific steps include:

[0161] S601 determines the standard obstruction status of the field replaceable unit when the maintenance party performs maintenance procedures based on the maintenance configuration information of the field replaceable unit, and determines the first visibility score corresponding to the maintenance procedure based on the standard obstruction status.

[0162] The so-called standard obstruction situation refers to the situation where the replaceable unit on site is obstructed when the maintenance party performs maintenance procedures; the so-called first visibility score is used to characterize the visibility of the replaceable unit on site when performing maintenance procedures.

[0163] Optionally, the maintenance steps can be used as an index to search the maintenance configuration information of the replaceable units in the field to obtain the standard occlusion conditions associated with the maintenance steps. Then, referring to the occlusion evaluation table, the first visibility score corresponding to the maintenance step can be determined based on the standard occlusion conditions.

[0164] For example, the occlusion status of the replaceable unit in the field can be evaluated with reference to Table 5 below. Table 5 is a reference occlusion evaluation table. The score in Table 5 is the first visibility score.

[0165] Table 5 Reference Occlusion Evaluation Table

[0166]

[0167] S602. Based on the actual obstruction of replaceable units on site when the maintenance party actually performs maintenance procedures, determine the second visibility score corresponding to the maintenance procedure.

[0168] The so-called actual obstruction situation refers to the obstruction situation of the replaceable unit on site when the maintenance procedure is actually performed; the so-called second visibility score is used to characterize the visibility of the replaceable unit on site when the maintenance procedure is actually performed.

[0169] Optionally, a second visibility score can be calculated based on the actual obstruction of the replaceable units on-site during the maintenance process. For example, Table 5 above can be used to evaluate the visibility of the replaceable units on-site.

[0170] S603, based on the first visibility score and the second visibility score, determine the maintenance evaluation value of the maintenance steps for the field replaceable unit under the visibility analysis dimension.

[0171] Optionally, a score can be selected from the first visibility score and the second visibility score as the maintenance evaluation value of the field replaceable unit maintenance steps under the visibility analysis dimension. For example, the smaller score between the first and second visibility scores can be directly used as the maintenance evaluation value of the field replaceable unit maintenance steps under the visibility analysis dimension.

[0172] For example, when multiple LRUs exist simultaneously, and each LRU corresponds to multiple maintenance steps, the first visibility score E of the j-th maintenance step in the i-th LRU can be calculated by referring to step S601 above. 5ij Then, refer to the following formula (11) to calculate the first visibility score E5 of the target device as a whole.

[0173] (11)

[0174] Furthermore, referring to step S602 above, the second visibility score F for the j-th maintenance step in the i-th LRU can be calculated. 5ij Then, referring to the following formula (12), the second space score F5 of the target equipment as a whole is calculated.

[0175] (12)

[0176] Then, G5 can be determined by referring to the formula G5=min{E5,F5}. Here, G5 is the overall maintenance evaluation value of the target equipment under the visibility analysis dimension.

[0177] In this embodiment of the application, by determining a first visibility score based on standard occlusion conditions and a second visibility score corresponding to the maintenance steps based on actual occlusion conditions, the maintenance evaluation value of the maintenance steps of the field replaceable unit under the visibility analysis dimension can be calculated, thus ensuring the reliability of the maintenance evaluation value calculation.
