FIG.

First, the background of the present invention will be described.
In the manufacturing industry, there is a labor shortage these days, and it is difficult to secure enough workers. In addition, workers engaged in product manufacturing tend to have less job satisfaction because they are doing more repetitive work. In this situation, there have been many technologies that focus on either the job satisfaction of workers working at the production site or the productivity of the factory. However, in light of the above background, it is required to balance both the job satisfaction of workers and the productivity of the factory, and no means for solving such a problem have been provided. Therefore, the above circumstances have been taken into consideration to create an embodiment of the present invention. According to the embodiment of the present invention, it is possible to take action on workers working at the production site so that the job satisfaction of workers and the productivity of the factory are brought closer to the optimal state, and to support the improvement of the job satisfaction of workers.

The management server 2 may be a cloud server.

FIG. 3 is a diagram illustrating an example of the functional configuration of the management server 2.
As shown in FIG. 3, a site activation support program 22 is installed in the management server 2 of this embodiment.
The site revitalization support program 22 has a job satisfaction acquisition unit 220 , a productivity acquisition unit 222 , a site evaluation unit 224 , an output control unit 226 , a visualization unit 228 , an evaluation result distribution unit 230 , and a utilization evaluation unit 232 .
A part or the whole of the on-site activation support program 22 may be realized by hardware such as an ASIC. The on-site activation support program 22 is stored in a recording medium such as a CD-ROM, and is installed via the recording medium.

The job satisfaction acquisition unit 220 acquires job satisfaction evaluation information 11 indicating the job satisfaction of workers working at the production site, acquired from the job satisfaction acquisition device 3. The job satisfaction acquisition unit 220 acquires at least one of job satisfaction evaluation information 11A based on the so-called subjective job satisfaction of the worker and job satisfaction evaluation information 11B based on the so-called objective job satisfaction of the worker. Note that the job satisfaction evaluation information 11A and the job satisfaction evaluation information 11B are simply referred to as job satisfaction evaluation information 11 when there is no particular need to distinguish between them.
The job satisfaction acquisition unit 220 generates the job satisfaction evaluation information 11A based on, for example, a survey result or a report by a worker acquired by the client terminal 3A. The evaluation of the survey result or report by a worker corresponds to a so-called subjective evaluation of the worker's job satisfaction. The job satisfaction evaluation information 11A in this example is generated based on the results of a survey conducted on specific workers at weekly or monthly intervals and tabulated, and a report reporting feelings toward the work when performing each task.

The job satisfaction acquisition unit 220 also evaluates the movement of a specific part of the worker or the amount of communication between workers based on the image data captured by the image capture device 3B, and generates the evaluation result as job satisfaction evaluation information 11B. The evaluation of the movement of a specific part of the worker or the amount of communication between workers corresponds to the so-called objective evaluation of the worker's job satisfaction. Here, the movement of a specific part is, for example, a change in facial expression, eye movement, or the movement of the worker's skeleton. The job satisfaction evaluation information 11 in this example generates the evaluation result of the movement of a specific part of the worker and the amount of communication between workers as job satisfaction evaluation information 11. Specifically, the job satisfaction evaluation information 11 evaluates the change in facial expression and eye movement indicating the concentration level, sleepiness level, or fatigue level, the skeletal movement of the worker indicating the degree of work sharpness based on the skeletal movement distance and speed during work, and the amount of communication between workers indicating the closeness of the spatial distance between the workers and the length of conversation time, and generates the evaluation result as job satisfaction evaluation information 11B.

Further, the job satisfaction acquisition unit 220 evaluates the vital data measured by the vital data measurement device 3C and generates the evaluation result as job satisfaction evaluation information 11B. The evaluation of the vital data corresponds to an objective evaluation of the worker's job satisfaction. The job satisfaction acquisition unit 220 in this example acquires and evaluates emotions such as joy, anger, sorrow, happiness, sleepiness, etc. from the pulse rate and brain waves.
Furthermore, the job satisfaction acquisition unit 220 evaluates the voice of the worker during work or specific keywords acquired by the microphone 3D, and generates the evaluation result as job satisfaction evaluation information 11B. The evaluation of the voice of the worker during work and the specific keywords corresponds to a so-called objective evaluation of the worker's job satisfaction. In this example, the job satisfaction acquisition unit 220 evaluates the worker's job satisfaction based on emotion analysis of the worker's tone of voice during work, or specific keywords such as "okay" or "tired", and generates the evaluation result as job satisfaction evaluation information 11B.

The productivity acquisition unit 222 acquires productivity evaluation information 12 indicating the productivity of the production site, acquired from the factory equipment information management device 5. The productivity acquisition unit 222 generates the productivity evaluation information 12 based on information indicating the operation status of production machines installed at the production site (hereinafter, production machine operation information), the defect rate of products produced at the production site (hereinafter, defect rate), or the work time at the production site (hereinafter, work time), acquired by a production management system, an IoT device, or the like. The productivity acquisition unit 222 in this example generates the productivity evaluation information 12 based on, for example, the indoor temperature, the indoor _CO2 concentration, the production machine operation information, the operation time, the defect rate, and the work time.

The site evaluation unit 224 generates site evaluation information 13 for evaluating the production site based on the job satisfaction evaluation information 11 acquired by the job satisfaction acquisition unit 220 and the productivity evaluation information 12 acquired by the productivity acquisition unit 222. The site evaluation unit 224 generates site evaluation information 13 for each individual worker, each group, or both of workers at the production site. Here, a group is, for example, a production line unit where line work is performed, or a work process unit. The site evaluation unit 224 also generates site evaluation information 13 for each time period. The site evaluation unit 224 also generates site evaluation information 13 for evaluating the production site by scoring.

The output control unit 226 controls the output device 9 installed at the production site based on the site evaluation information 13 generated by the site evaluation unit 224. As a result, the output device 9 outputs music, light, or content consisting of text or images according to the control by the output control unit 226. Specifically, the output control unit 226 controls the speaker 9A to output music, the lighting device 9B to output light, and the signage 9C and the client terminal 9D to output content consisting of text or images.
In addition, the output control unit 226 analyzes the change in the on-site evaluation information 13 by the on-site evaluation unit 224 when the output by the output device 9 is changed, and optimizes the content, timing, or output location of the output by the output device 9. For example, the output control unit 226 may output music with a relaxing effect from the speaker 9A at the timing of a break time, or output music from the speaker 9A at the timing of updating or paying attention to the signage 9C. In addition, the output control unit 226 may change the color temperature of the lighting device 9B between the break time and the work time after the break. Specifically, the lighting may be switched to a color temperature of warm white or white during the break time, and switched to a color temperature of daylight white or daylight during the work time after the break. In addition, the output control unit 226 may output to the signage 9C with display content or a display method that improves the worker's motivation when seen by the worker. In addition, the output control unit 226 in this example causes the signage 9C to output optimized information. For example, the output control unit 226 assigns a score based on the content output to the output device 9 and information on the workers viewing the output content (viewing time, emotion analysis based on facial expressions captured by a camera, etc.), and customizes and outputs the display method that has a high viewing score. This allows the output device 9 to output optimized information so that the worker's job satisfaction and the factory's productivity approach an optimal state.

The visualization unit 228 visualizes the on-site evaluation information 13 generated every hour in chronological order. The visualization unit 228 arranges the visualized on-site evaluation information 13 by day, week, month, or year, and visualizes it in chronological order. In this example, the visualization unit 228 assigns a score to the on-site evaluation information 13 for each individual or work group, and aggregates and visualizes it on a monthly basis. This allows the overall and individual scores to be grasped relatively, and also allows the items of the on-site evaluation information 13 that need to be improved to be grasped. Furthermore, while visualizing for each individual, the visualization unit 228 can also aggregate by age and years since joining the company, and data can be obtained to determine what age group has what awareness of issues.

The evaluation result distribution unit 230 distributes the on-site evaluation information 13 visualized by the visualization unit 228 to the output device 9. The evaluation result distribution unit 230 may distribute the on-site evaluation information 13 with a viewing range restriction so that a specific worker can view it, or may distribute the on-site evaluation information 13 with a viewing range determined according to the distribution destination. For example, when distributing the visualized on-site evaluation information 13 to the signage 9C or the client terminal 9D, when distributing the on-site evaluation information 13 with a viewing range restriction so that a specific worker can view it, the evaluation result distribution unit 230 may distribute the on-site evaluation information 13 with a viewing range restriction according to the job title or employment type of the worker. Also, when distributing the on-site evaluation information 13 with a viewing range determined according to the distribution destination, the on-site evaluation information 13 with a range that can be viewed by all workers may be distributed to the signage 9C, and the on-site evaluation information 13 with a viewing range restriction may be distributed to a portal site viewed on the client terminal 9D.

The utilization evaluation unit 232 evaluates the utilization of the on-site evaluation information 13 distributed by the evaluation result distribution unit 230. The utilization evaluation unit 232 evaluates the utilization of the on-site evaluation information 13 based on the number of accesses to the portal site or viewer information of the signage 9C (age, gender, viewing time, emotion, etc.).

Next, a state in which the on-site evaluation information 13 distributed by the evaluation result distribution unit 230 is displayed on the display screen of the digital signage 9C will be described. The display screen of the digital signage 9C is an example of a screen displayed when the thank-you card system is in operation.
FIG. 5 is a diagram illustrating an example of a display screen of the digital signage 9C.
As shown in FIG. 5, digital signage 9C displays the results of the count when the thank you card system is in operation. Signage 9C displays the monthly ranking of the total number of people who sent thank you cards, the total number of people who received thank you cards, and the total number of thank you cards submitted. For the total ranking of people who sent thank you cards, the "rank,""name of person who sent thank you cards," and "number of thank you cards sent" are displayed as an association table. For the total ranking of people who received thank you cards, the "rank,""name of person who received thank you cards," and "number of thank you cards sent" are displayed as an association table. For the total number of thank you cards submitted, the "monthly cumulative" and "monthly cumulative" are displayed as an association graph.

Next, the on-site activation support process (S10) in this embodiment will be described.
In describing this process, a case where output is made to a digital signage 9C will be described with reference to Figs. 4 and 5, taking an example of operation of a thank-you card system as a specific example.
FIG. 5 is a flow chart for explaining the on-site activation support process (S10).
5, in step S100 (S100), the client terminal 3A of the job satisfaction acquisition device 3 accepts a questionnaire result or a report from a worker describing the gratitude or praise for other workers, and transmits it to the management server 2. The job satisfaction acquisition unit 220 acquires job satisfaction evaluation information 11 from the questionnaire result and the report obtained from the worker working at the production site.

In step S102 (S102), the factory equipment information management device 5 transmits the indoor temperature of the factory, the _CO2 concentration in the factory, the production machine operation information, the operation time, the defect rate, and the work time to the management server 2. The productivity acquisition unit 222 acquires the productivity evaluation information 12 from the information indicating the productivity obtained from the production site.

In step S104 (S104), the on-site evaluation unit 224 generates on-site evaluation information 13 based on the job satisfaction evaluation information 11 acquired by the job satisfaction acquisition unit 220 and the productivity evaluation information 12 acquired by the productivity acquisition unit 222.

In step S106 (S106), the output control unit 226 determines whether the generated on-site evaluation information 13 is content consisting of text or images. If the output control unit 226 determines that the on-site evaluation information 13 is content consisting of text or images, it proceeds to processing of S108. If the output control unit 226 determines that the on-site evaluation information 13 is not content consisting of text or images, it proceeds to processing of S110.

In step S108 (S108), the visualization unit 228 visualizes the on-site evaluation information 13 generated by the on-site evaluation unit 224 in the form of a graph or table.

In step S110 (S110), the evaluation result distribution unit 230 distributes the visualized on-site evaluation information 13 to the signage 9C of the output device 9. Based on the distributed on-site evaluation information 13, the output control unit 226 outputs the on-site evaluation information 13 to the digital signage 9C as illustrated in FIG. 4, and the digital signage 9C displays the output on-site evaluation information 13 on the display screen.

In step S112 (S112), the output control unit 226 optimizes the display content of the site evaluation information 13 output to the signage 9C. The output control unit 226 assigns a score based on the display screen output to the signage 9C and information on the worker viewing the display screen (gazing time, emotion analysis based on facial expressions captured by a camera), and redisplays the information in a display method with a high viewing score. In other words, the information is output as information for revitalizing the production site.
In this way, according to this process, by displaying recommended contents to be output, it is possible to support improvement of worker job satisfaction.

As described above, the on-site revitalization support system 1 in this embodiment can take action on workers working at the production site to bring the job satisfaction of the workers working at the production site and the productivity of the factory closer to an optimal state, thereby supporting the improvement of the worker's job satisfaction.

(Modification)
In the above embodiment, the operation of the thank-you card system has been specifically explained, but it is also possible to score the evaluation of the on-site evaluation information 13 for each work group, and to display and advise work groups with low scores as areas to be improved, thereby supporting the improvement of job satisfaction as a work group.
