For example, the special work is a special work required based on the result of the visual inspection work.

Next, an example of work frequency evaluation will be described with reference to FIG.
FIG. 3 is a diagram showing a work frequency in the work performance evaluation apparatus according to Embodiment 1 of the present invention.

  In FIG. 3, the work frequency of all the workers, the work frequency of worker A, and the work frequency of worker B are shown.

  The total number of operations is “500” for all of the plurality of workers. The target work number is “280”. In this case, the work frequency is “0.56”.

  For worker A, the total number of operations is “16”. The number of target tasks is “8”. In this case, the work frequency is “0.50”.

  For worker B, the total number of tasks is “15”. The number of target operations is “4”. In this case, the work frequency is “0.27”.

At this time, the work frequency evaluation unit 9 calculates a p value as a test result. For example, the p value corresponding to the worker A is “0.826”. For example, the p value corresponding to the worker B is “0.046”. The larger the p value, the more appropriate the p value.

Next, an example of work interval distribution evaluation will be described with reference to FIG.
FIG. 4 is a diagram showing work intervals in the work performance evaluation apparatus according to Embodiment 1 of the present invention.

  In FIG. 4, the work interval distribution of all the workers, the work interval distribution of worker A, and the work interval distribution of worker B are shown.

  The frequency of the work interval for one month is “10” for all of the plurality of workers. The frequency of the work interval of 2 months is “5”. The frequency of the work interval of 3 months is “20”. The frequency of the work interval of 4 months is “5”. The frequency of the work interval of 5 months is “40”.

  For example, the work interval distribution evaluation unit 10 performs a correlation test on the work frequencies of all of the plurality of workers and the work frequencies of the plurality of workers, and evaluates the work frequencies of the plurality of workers. At this time, the work interval distribution evaluation unit 10 calculates a p value as a test result. For example, the p value corresponding to the worker A is “0.0005”. For example, the p value corresponding to the worker B is “0.168”. The smaller the p value, the more appropriate the p value.

Next, an example of an identification method for determining whether or not the input of work results is appropriate will be described with reference to FIG.

  Regarding the worker B, the p value of the work frequency is “0.046”. The p value of the work interval distribution is “0.168”. In this case, the appropriate evaluation identifying unit 11 identifies that the input of the work result of the worker B is not appropriate.

  The boundary value is corrected so as to approach the coordinates corresponding to the newly identified worker if the work performance input is not appropriate. For example, the boundary value is corrected by a linear classifier. For example, the boundary value is corrected by a nonlinear classifier.

Next, the flow of processing by the evaluation apparatus 3 will be described with reference to FIG.
FIG. 6 is a flowchart for explaining the flow of processing by the work performance evaluation apparatus according to Embodiment 1 of the present invention.

  In step S1, the evaluation plane information storage unit 4 stores initial evaluation plane information based on an external input operation. Thereafter, the process of step S2 is performed.

  In step S <b> 2, the work frequency totaling unit 5 totals the number of work per fixed time from the information in the work performance database 1 as the work frequency. For example, the work frequency totaling unit 5 totals the number of work per year as the work frequency. Thereafter, the process of step S3 is performed.

  In step S3, the work frequency evaluation unit 9 compares the work frequencies of all of the plurality of workers with the work frequencies of the plurality of workers, and tests the difference in the population ratio for each of the plurality of workers. In this case, the p value is calculated as “p_a”. Thereafter, the process of step S4 is performed.

  In step S4, the work interval distribution totaling unit 6 totals the frequency for each work interval as the work interval distribution from the information in the work record database 1. Thereafter, the process of step S5 is performed.

  In step S5, the work interval distribution evaluation unit 10 compares the work interval distributions of all of the plurality of workers with the respective work interval distributions of the plurality of workers, and performs a correlation test for each of the plurality of workers. The p value in this case is calculated as “p_b”. Thereafter, the process of step S6 is performed.

  In step S6, the appropriate evaluation identifying unit 11 identifies whether “p_a” and “p_b” of each of a plurality of workers have been calculated for all the operations. When “p_a” and “p_b” of each of the plurality of workers are not calculated for any of the tasks in step S6, the processing from step S2 to step S5 is performed on the task. When “p_a” and “p_b” of each of the plurality of workers are calculated for all the operations in step S6, the process of step S7 is performed.

  In step S7, the appropriate evaluation identifying unit 11 determines whether or not the coordinates (p_a, p_b) corresponding to each of the plurality of workers exist in the appropriate range for each of the plurality of operations based on the information on the current evaluation plane. And whether or not the input of the work results of each of the plurality of workers is appropriate. Thereafter, the process of step S8 is performed.

  In step S <b> 8, the evaluation plane information correction unit 12 evaluates that the input of all the work records of the workers whose work ratios identified as the work record inputs are not appropriate is greater than or equal to the inappropriate exclusion threshold value. Thereafter, the process of step S9 is performed.

  In step S <b> 9, the evaluation plane information correction unit 12 uses coordinates corresponding to a worker who has been newly identified that the boundary value when determining whether or not the input of work results is appropriate is the input of work results is not appropriate. The information on the evaluation plane is corrected so as to approach. Then, the process of step S10 is performed.

  In step S10, the appropriate information extraction unit 13 determines whether or not the correction of the information on the evaluation plane has converged. If the correction of the evaluation plane information has not converged in step S10, the process of step S7 is performed. If the correction of the evaluation plane information has converged in step S10, the process of step S11 is performed.

  In step S <b> 11, the appropriate information extraction unit 13 extracts information on the work performance of the worker identified as having an appropriate work performance input. Thereafter, the process ends.

  According to Embodiment 1 demonstrated above, the information of the work performance of the worker identified as the input of work performance is appropriate is extracted. For this reason, high quality evaluation can be performed on the accumulated work performance.

  For example, information that can be automatically excluded can be excluded in advance even for information on work results that require some human judgment. For this reason, the range which should be judged by a person can be limited. As a result, high quality evaluation can be performed.

  For example, even when a measure for improving the input quality of work performance information is implemented, the information accumulated before the measure is implemented can be used. As a result, information accumulated over a long period of time can be used effectively.

  Further, whether or not the input of the work record is appropriate is identified in consideration of not only the work frequency but also the work interval distribution. For this reason, it is possible to more accurately extract information on proper work results.

  In addition, the evaluation criteria are updated while correcting the characteristics of ease of input of work results according to the type of work. For this reason, it is possible to more accurately extract information on proper work results.

  In addition, it is evaluated that the input of the work results is not appropriate for the worker whose ratio of the work results identified as not being appropriate for the plurality of types of work results is equal to or more than the inappropriate exclusion threshold. At this time, information corresponding to a worker whose work performance input is too small is excluded. Information corresponding to workers with excessive work results input is excluded. For this reason, it is possible to more accurately extract information on proper work results.

  The correction of the evaluation plane information may be terminated when it is repeated a preset number of times. In this case, it is possible to shorten the time until the work performance information is extracted.

  Further, the work performance database 1 and the proper work performance database 2 may be provided in the evaluation device 3. In this case, high-quality evaluation can be performed on the accumulated work performance without communication with other devices.

  Moreover, you may provide the work performance database 1 and the appropriate work performance database 2 in the computer of a building management company. In this case, if the evaluation apparatus 3 is automatically operated, the work management information of the worker who has been identified as appropriate in the work management company can be maintained in a new state.
