The processing flow of the periodic maintenance scheduling system using the periodic maintenance scheduling device configured as described above will be described below with reference to FIG. Standard capacity data for each device 6, maintenance plan data for each device 6,
The reference information 3 such as the number of maintenance personnel and the operation time is input from the input device 4 in advance, stored in the disk 2, and can be taken out as needed. First, processing information 8 such as a processing start time, a processing completion time, a processing amount, and a processing number is collected from each device 6 by the processing information collection device 7 and transmitted to the computer 1 (processing information collection 11 of the device; step S1). ).
Based on the processing information 8 and the standard performance data of the reference information 3, the computer 1 verifies the processing performance to determine whether or not the processing performance of each device 6 satisfies the standard processing performance (processing capability of the device). Verification 12; Step S2).

After confirming the processing capacity of each device 6, based on the reference information 3 and the processing information 8, the computer 1 controls the work load time of the maintenance staff and the processing capacity of the device 6 so as to equalize.
Thus, a daily periodic maintenance schedule is created (daily periodic maintenance schedule creation 13; step S3). Based on the above-mentioned daily regular maintenance schedule, a regular maintenance time schedule per day is created (regular maintenance time schedule creation 14; step S4). Next, the periodic maintenance time schedule is displayed on the output device 9 to instruct maintenance personnel to perform maintenance work (display 15; step S).
5). Thereafter, after the periodic maintenance is performed, the performance report 5 is input from the input device 4 by the maintenance staff (the periodic maintenance performance report 16; step S6).

As described above, in the periodic maintenance scheduling according to the present embodiment, the reference information 3 is previously input from the input device 4 and stored in the disk 2, and the processing information collecting device 7 is used to collect the processing information of the device. 11, the computer 1 verifies the processing capacity of the equipment 12, and then creates a daily regular maintenance schedule 13, and further prepares a regular maintenance time schedule so as to equalize the workload of the maintenance staff and the processing capacity of the equipment 6. Creation 14 is performed, and it is displayed 15 on the output device 9 to instruct maintenance personnel to perform maintenance work. Thereafter, the regular maintenance result report 16 is performed from the input device 4. For this reason, even if the scale of the plant increases and the number of devices increases and the number of maintenance items becomes enormous, the periodic maintenance scheduling can be automatically performed in a short time. Further, since the work load time of the maintenance staff and the processing capacity of the equipment 6 can be leveled, each equipment can be operated stably and with high reliability, and the maintenance staff is not overloaded.

In this embodiment, the input of the reference information 3 and the periodic maintenance result report 16 are performed from the input device 4, and the periodic maintenance schedule is displayed 15 from the output device 9 as a display device. As a device capable of output, both the input of the periodic maintenance result report 16 and the display 15 of the periodic maintenance schedule may be performed by this display device, and the reference information 3 may be input from the input device 4.

Embodiment 2 Next, a process in which individual conditions are further added to the periodic maintenance scheduling system shown in the above-described first embodiment as a second embodiment will be described in detail below.

FIGS. 3 to 5 are flowcharts for explaining in detail steps S1 to S6 of the processing flow of the periodic maintenance scheduling system shown in FIG. First, as shown in FIG. 3, processing information 8 such as a processing start time, a processing completion time, a processing amount, and a processing number is collected from each device 6 by the processing information collecting device 7 (step S1).
1), and transmits it to the computer 1 (step S12). Thus, the processing information collection 11 of the device (step S1) is completed.

Next, the actual processing capacity 17 of each device 6 for a predetermined period up to the present time is derived from the processing information 8. The actual processing capacity 17 is derived from, for example, the total number of processes (step S21). Next, it is determined whether or not the actual processing capacity 17 satisfies the standard processing capacity 18 represented by, for example, the standard processing number in the reference information 3 (step S22), and the actual processing capacity 17 <the standard processing capacity 18 If the device 6
The standard processing capacity 18 in the reference information 3 is rewritten to the numerical value of the temporary actual processing capacity 17 (step S23), and the changed contents are displayed on the output device 9 and reported to the maintenance staff (step S24). Thus, the processing capability verification 12 (step S2) of the device is completed.

Next, as shown in FIG. 4, for the periodic maintenance based on the cycle determined by the elapsed period, a daily periodic maintenance schedule 19 for a predetermined period from the reference date is set in step S.
6, the data of the regular maintenance completion date of each device 6 based on the periodic maintenance result report 16 and the cycle of the periodic maintenance of each device 6 in the reference information 3, in this case, the data of the standard date.
In the case of the first regular maintenance in each device 6, the data of the regular maintenance completion date is set to the initial value (step S3).
01). Next, for the periodic maintenance by a cycle determined by the number of processes, the amount of processing, or the processing time other than the elapsed period, the daily periodic maintenance schedule 20 for a predetermined period from the reference date is obtained by the data from the periodic maintenance result report 16 in step S6. , The periodic maintenance cycle of each device 6 in the reference information 3, and the processing information 8 based on the reference information 3 of each device 6.
It is created by estimating from the standard processing capacity 18 within. Also in this case, in the case of the first regular maintenance in each device 6, the data based on the regular maintenance result report 16 is set to the initial value (step S302).

Next, the two daily periodic maintenance schedules 19 and 20 created in step S301 and step S302 are combined, and the daily periodic maintenance schedule 2 is synthesized.
1 is created (step S303), and the regular maintenance schedule 22 for each area is extracted from the combined regular maintenance schedule 21 for each day (step S304). Next, in the extracted periodic maintenance schedules for each area 22, the daily total time 23 of the periodic maintenance is calculated based on the cumulative maintenance time required for the periodic maintenance of each device 6 in the reference information 3 (step S 305). Further, in the extracted periodic maintenance schedule 22 for each area, as the total time for each periodic maintenance day for each device 6, the average cumulative time for daily maintenance 2 for each group of devices 6 that process the same type or the same process is used.
4 is calculated. At this time, a plurality of devices 6 in the device 6 group
In addition to averaging by numbers, for example, the total maintenance time required for periodic maintenance of a group of devices 6 for a predetermined period (for example, one week) including the target day is calculated by multiplying the number of days and the number of devices 6 in the predetermined period. The average is calculated by dividing, for example, even during a predetermined period (step S306).

Next, based on the number of maintenance personnel for each area in the reference information 3, the total maintenance work time 25 in which the maintenance personnel can work per day for each area is calculated (step S 307). The standard operating time 26 per day for each of the six groups of devices is calculated as the standard operating time for each device (step S308). Thereafter, whether the total maintenance work time 25 ≧ the cumulative total time 23 of the periodic maintenance is satisfied, that is, whether the cumulative time required for the periodic maintenance is within the workable time of the maintenance staff, and (operating time−equipment) The standard operation time 26 per group 6) ≧ the average cumulative time 24 of the periodic maintenance for each of the six groups of equipment, that is, the cumulative time required for the periodic maintenance for each of the six groups of equipment is within the operating hours of the day. It is determined whether the time falls within the non-operation time and the standard operation time is secured (step S309).
If this determination criterion is not satisfied, the periodic maintenance by the cycle determined by the elapsed period is moved forward with priority, and if not possible, the period is moved back within the range of the maximum allowable date, and the process returns to step S301. The process is repeated until the criterion of step S309 is satisfied (step S311).

At this time, if the criterion of step S309 is not satisfied, immediately after that, it is determined whether or not all cases have been considered (step S310). If the judgment criteria are not satisfied, the area-specific periodic maintenance schedule 22 of the optimal case is extracted (step S312), and the daily maintenance time 23 of the periodic maintenance is exceeded, or the periodic maintenance average cumulative time 24 for the six groups of devices 6 is exceeded. Is displayed on the output device 9, and
A report is sent to the maintenance staff (step S313). Thereby, the daily periodic maintenance schedule creation 13 (step S3) is completed.

Next, as shown in FIG. 5, in order to create the area-specific periodic maintenance schedule 22 for each time zone, the periodic maintenance according to the cycle determined by the number of processes, the amount of processing, or the processing time is preferentially performed for the estimated time. The periodic maintenance according to the cycle determined by the elapsed time is performed by allocating the maintenance time from the operation start time of the day (step S41), making adjustments, and creating the periodic maintenance time schedule 27 for each area (step S42). This completes the regular maintenance time schedule creation 14 (step S4). Next, the periodic maintenance time schedule 27 is displayed on the output device 9 before the scheduled maintenance time, and maintenance personnel are instructed to perform maintenance work. Thus, the display 15 (step S5) is completed.

Thereafter, after the periodic maintenance is performed, the performance report 5 is input from the input device 4 by the maintenance staff. At this time,
It is determined whether or not the performance report 5 has been input (step S
61) If the performance report 5 is not implemented, output device 9
Alarm to notify maintenance personnel (step S6)
2). Thereafter, if the performance report 5 is not performed on the scheduled maintenance date, the process returns to step S11 to perform scheduling again so that the date and time of the periodic maintenance can be postponed and performed with the highest priority (step S63). When the performance report 5 is input from the input device 4, the periodic maintenance cycle in the reference information 3 is reviewed as necessary based on the quality information of the device 6, and the process proceeds to step S11 to perform the next scheduling. Return (step S64). Thus, the periodic maintenance result report 16 (step S6) is completed.

As described above, in the periodic maintenance scheduling according to the present embodiment, in step S309, the total time of the maintenance work 25 ≧ the daily total time of the periodic maintenance 2
3, and (operating time−standard operating time 26 per group of equipment 6) ≧ average cumulative period of regular maintenance 24 per apparatus 6 group,
If the condition is not satisfied, or if it is not possible, an area-based periodic maintenance schedule 22 in an optimal case close to the condition is extracted. In this manner, the area-specific regular maintenance schedule 22 is created so that the total maintenance work time 25 does not exceed the total operation time 26 and the standard operation time 26 for each group of devices 6 can be secured. For this reason, the work load time of the maintenance staff and the processing capacity of the equipment 6 can be easily and effectively leveled, and each equipment 6 can be operated stably and with high reliability, and an excessive load is applied to the maintenance staff. Not even.

Further, in order to level the processing capacity of the equipment 6, the average daily maintenance time 24 is calculated for each group of equipment 6 which processes the same type or the same process. As described above, since the periodic maintenance is group-managed for each group of devices 6, the processing capability of the devices 6 can be effectively leveled. Furthermore, the average periodical maintenance time 24 per day is calculated by averaging even during a predetermined period including the target day. For this reason, even if there is a maintenance item that requires a long maintenance time, for example, most of the operation time of a day, the processing capacity of the device 6 can be secured on average over a predetermined period, and the processing capacity of the device 6 can be reduced. Leveling can be performed effectively.

Further, since the area information is input and the area-specific periodic maintenance schedule 22 is automatically created, it is possible to cope with a large-scale plant. Furthermore, after the area-specific periodic maintenance schedule 22 is created, the area-specific periodic maintenance time schedule 27 is automatically created and displayed, so that maintenance personnel are instructed. In addition, the instructions to the maintenance staff are accurate, and the maintenance work can be smoothly performed.

In this embodiment, in order to equalize the processing capacity of the equipment 6, the average periodical maintenance time 24 per day is calculated for each group of equipment 6 which processes the same type or the same process. It is not necessary to consider it as a group of devices 6, and it may be calculated for each device 6 according to the situation of the plant, or may be selected for each process or type. The average cumulative time 24 of the regular maintenance per day is calculated by averaging even during a predetermined period including the target day, but if there is no maintenance item that requires a long maintenance time depending on the condition of the plant, The calculation may be performed only on the target day.

Further, in this embodiment, the periodic maintenance schedule 22 for each area is created, but when the size of the plant is small and the maintenance staff is maintaining the whole plant,
Create daily maintenance schedules and maintenance time schedules for the entire plant. Further, in this embodiment, as the area divided in the plant, the work range of the maintenance staff in the plant is used. However, the present invention is not limited to this, and may be a geographical section in the plant.

Furthermore, in this embodiment, the periodic maintenance scheduling is all performed automatically. However, a person inputs from the input device 4 a change of the automatically created periodic maintenance schedule or a reservation of the date and time of the periodic maintenance. With the means,
The flexibility of scheduling is improved, and a highly reliable periodic maintenance scheduling system can be obtained.
