Furthermore, the video display section 65 will show both the improved video and the problematic video before the improvement for the improvement example shown in the improvement example details 69. 【0029】 (Calculation process for standard unit costs) Next, the standard unit cost setting process in the standard unit cost setting unit 31 of the data processing unit 30 will be explained with reference to the flowchart in Figure 8. Figure 8 shows the processing steps for calculating and setting standard unit costs for each piece of equipment, model, and operating state. First, in order to calculate the minimum, maximum, average, standard deviation, and standard value of the unit cost for each piece of equipment, model, and operating state, the measured values ​​and production quantities are analyzed. To do this, the user selects equipment from the equipment master database 23, sets the period and production quantity range that the user wants to analyze, obtains that period and production quantity range from the measured value database 21 and the production quantity database 22, and extracts the measured values ​​for the production quantity range of the set period (step S101). The distribution of unit costs for each measured value extracted from the extracted measured values ​​and the unit costs extracted from the unit cost database 24 is analyzed (step S102). In the analysis, the minimum and average values ​​in the distribution of unit costs are found, and it is determined whether the amount of distribution between the minimum and average values ​​of the unit costs is 70% or more of the total (step S103). If the distribution of the minimum and average unit values ​​accounts for 70% or more of the total (Step S103: Yes), it is determined that the system is operating stably, and the minimum unit value is set as the baseline (Step S104). If the distribution of the minimum and average unit values ​​accounts for less than 70% of the total (Step S103: No), it is determined whether the distribution of the minimum and average unit values ​​accounts for 40% or more of the total (Step S105). If the distribution of the minimum and average unit values ​​accounts for 40% or more of the total (Step S105: Yes), it is determined that the system is in the process of improvement, and 90% of the average unit value is set as the baseline (Step S106). If the distribution of the minimum and average unit values ​​accounts for less than 40% of the total (Step S105: No), it is determined that no improvement has been implemented, and the average unit value is set as the baseline (Step S107). The above percentages can be arbitrarily set by the user. The reference values ​​determined in steps S104, S106, and S107 are set as the reference unit values ​​(step S108). Next, the minimum, maximum, average, standard deviation, and reference unit values ​​for each piece of equipment, model, and type are calculated and recorded in the model unit value database 25 (step S109).Similarly, the minimum, maximum, average, standard deviation, and reference unit values ​​for each piece of equipment, type, and operating condition are calculated and recorded in the condition unit value database 26 (step S110). 【0030】 (Extraction process of reference work video) Next, the standard work video extraction process for each model and operating state in the standard work video extraction unit 32 of the data processing unit 30 will be explained with reference to the flowchart in Figure 9. In the standard work video extraction process, in order to extract standard work videos for each target model and operating state, the standard unit consumption and actual unit consumption are analyzed and videos are extracted. When the user selects equipment from the equipment master database 23 and sets the period that the user wants to analyze, the standard work video extraction unit 32 extracts the standard unit consumption for each model and operating state for that period from the model unit consumption database 25 and the state unit consumption database 26 (step S201). Next, based on the standard unit consumption for each model and operating state extracted in step S201, the standard work video extraction unit 32 extracts the actual unit consumption that is closest to that standard unit consumption from the model unit consumption database 25 and the state unit consumption database 26 (step S202). When the actual unit cost closest to the standard unit cost is extracted, the standard work video extraction unit 32 extracts videos within the range of the extracted actual unit cost from the video database 27 and records them in the video database 27 as standard work videos (step S203). 【0031】 (Calculation process for age-related deterioration) Next, the aging deterioration calculation process in the aging deterioration calculation unit 33 of the data processing unit 30 will be explained with reference to the flowchart in Figure 10. The aging deterioration calculation process analyzes the standard unit consumption for each piece of equipment, model, and operating state to calculate the aging deterioration of the target equipment, and calculates the difference between the past and present standard unit consumption. When the user selects equipment from the equipment master database 23 and sets the period that the user wants to analyze, the aging deterioration calculation unit 33 extracts the standard unit consumption for each model and operating state from the model unit consumption database 25 and the state unit consumption database 26 (step S301). Next, the aging deterioration calculation unit 33 extracts the standard unit consumption for each current model and operating state from the model unit consumption database 25 and the state unit consumption database 26 (step S302). For the standard unit consumption for each model and operating state extracted in steps S301 and S302, the aging deterioration calculation unit 33 calculates the difference between the two to determine the aging deterioration (step S303). 【0032】 (Calculation process for individual equipment differences) Next, the equipment individual difference calculation process in the equipment individual difference calculation unit 34 of the data processing unit 30 will be explained with reference to the flowchart in Figure 11. The equipment individual difference calculation process analyzes the standard unit consumption for each piece of equipment, model, and operating state to calculate the difference in the standard unit consumption for each piece of equipment. When the user selects equipment from the equipment master database 23 and sets the period that the user wants to analyze, the equipment individual difference calculation unit 34 extracts the standard unit consumption for each piece of equipment, model, and operating state from the model unit consumption database 25 and the state unit consumption database 26 (step S401). Then, the equipment individual difference calculation unit 34 calculates the difference in the standard unit consumption for each piece of equipment for each extracted model and operating state to determine the individual difference of the equipment (step S402). 【0033】 (Process for calculating room for improvement) Next, the improvement potential calculation process in the improvement potential calculation unit 35 of the data processing unit 30 will be explained with reference to the flowchart in Figure 12. The improvement potential calculation process calculates the unit cost that differs from the average unit cost and the reference unit cost, and extracts the video footage taken during that period. The system extracts the machine models and operating conditions that had a difference in unit cost during the target period, and calculates the improvement potential by checking the video footage and the reference video footage at that time. The user selects the equipment from the equipment master database 23 and sets the period and production quantity range that the user wants to analyze. The improvement potential calculation unit 35 then extracts the measured values ​​for that range from the measured value database 21 (step S501). Next, the improvement potential calculation unit 35 selects the reference unit cost for the period that the user wants to analyze from the machine unit cost database 25 and the state unit cost database 26 (step S502). The improvement potential calculation unit 35 also calculates the average unit cost for the period set by the user (step S503). The improvement area calculation unit 35 calculates the difference between the average unit cost for the set period calculated in step S503 and the standard unit cost selected in step S502 (step S504). Next, the improvement area calculation unit 35 extracts the models and operating conditions that had a difference in unit cost from the model unit cost database 25 and the condition unit cost database 26 (step S505). From the extracted models and operating conditions that had a difference in unit cost, the improvement area calculation unit 35 extracts the worst actual unit cost from the model unit cost database 25 and the condition unit cost database 26, extracts the video and standard video from the video database 27 at that time, and calculates the improvement area (step S506). 【0034】 (Process for extracting improvement examples) Next, the improvement case extraction process in the improvement case extraction unit 36 ​​of the data processing unit 30 will be explained with reference to the flowchart in Figure 13. The improvement case extraction process extracts the models and operating conditions that had differential unit consumption and extracts improvement cases to propose improvement cases to the user. The improvement case extraction unit 36 ​​extracts the models and operating conditions that had differential unit consumption from the model unit consumption database 25 and the state unit consumption database 26 (step S601). The improvement case extraction unit 36 ​​extracts improvement cases from the improvement case database 28 that correspond to the models and operating conditions that had differential unit consumption extracted in step S601 and proposes improvement cases to the user (step S602). 【0035】 (Process for calculating improvement effect) Next, the improvement effect calculation process in the improvement effect calculation unit 37 of the data processing unit 30 will be explained with reference to the flowchart in Figure 14. The improvement effect calculation process proposes an improvement effect to the user based on the difference in unit costs before and after improvement of the improvement target range. When the user selects an improvement example they would like to refer to, the improvement effect calculation unit 37 extracts the content of the selected improvement example from the improvement example database 28 (step S701). The user makes improvements based on the improvement example, extracts a video from the video database 27 showing the scope of the improvements implemented, checks the extracted video, and inputs whether the content of the improvement target range passed or failed. The improvement effect calculation unit 37 determines whether improvements were made based on the improvement example based on the user's input (step S702). If, based on the user's input, it is determined that the improvements implemented based on the improvement examples were effective (Step S702: Yes), the improvement effect calculation unit 37 calculates the improved unit cost for the improvement target range from the equipment master database 23, measurement value database 21, and production quantity database 22, and records it in the machine unit cost database 25 and the state unit cost database 26 (Step S703). On the other hand, if, based on the user's input, it is determined that the improvements implemented based on the improvement examples were not effective (Step S702: No), the process returns to Step S701, extracts the contents of other improvement examples, and presents them to the user. After the processing in Step S703 is completed, the improvement effect calculation unit 37 calculates the difference between the pre-improvement unit cost and the post-improvement unit cost for the improvement target range from the machine unit cost database 25 and the state unit cost database 26, and proposes the improvement effect to the user (Step S704). 【0036】 This disclosure allows for various embodiments and modifications without departing from the broad spirit and scope of this disclosure.
