Description

The present invention relates to a work performance analysis server, a work performance analysis method, and a work performance analysis program.

At some manufacturing sites that handle made-to-order manufacturing, frequent specification changes and design changes occur due to customer circumstances after an order is received, making it impossible to create a process master that defines the work that divides the order and its work period. Therefore, there is a problem that a work plan cannot be created. Therefore, the design and manufacturing departments set production periods based on past production results of similar products and their own experience and intuition.

Since there is no process master at the manufacturing site, the site leader issues the day's work instructions to the workers every morning. Because workers perform the work they are instructed to do on the day based on their experience, there are variations in work time. After completing work, the worker self-reports the amount of work done by recording the day's work results on a paper work list.

Therefore, the site leader cannot grasp the true production capacity of the workers and cannot compare the work plan and actual results. Additionally, it is not possible to collect and record detailed work results such as when, who worked on which product, and how many hours of work was done, making it impossible to analyze the process. This causes problems such as loss of order opportunities, increased outsourcing costs, and an increase in overtime due to inability to level out work.

As conventional work management, there is an invention described in Patent Document 1. Patent Document 1 describes an invention that calculates a target time for each work process from the number of element works included in at least one work process and the basic time for element work determined as the basic time required for the element work. ing.

Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the respective figures.

《Issues at the production site in the comparative example》
The production site of the comparative example produces a wide variety of products in small quantities. At this site, the manager (site leader) sets a production period on a weekly basis, taking into account sufficient slack time and referring to the results and experience of similar products in the past. This operation relies on the experience of the manager, so there is a possibility that the margin time is set for a long time and that a highly accurate production planning process is not established. Additionally, since the work instructions are changed every morning, there is the problem that a process master cannot be created.

At the production site of the comparative example, the site leader regularly gives verbal work instructions to the workers. This operation has a problem in that it is not possible to compare work plans and actual results (process analysis).

The instructed work is left to the experience of the worker. If the product is produced within the production plan period, it is judged to be in an appropriate state. In this operation, the net work time for each work item is not known, and the interrupt work time cannot be known, so the problem is that the true production capacity of each worker is not known.

At the production site in the comparative example, workers self-report their daily output on a paper performance collection form, enter the results into a terminal, and create a daily report. This method has the problem of not being able to analyze product processes because it is not possible to collect and record work results such as when, who worked on which product, and how many hours of work was done.

《Work performance analysis system of this embodiment》
The work performance analysis system of this embodiment evaluates the ratio of standard time to the production period as a margin based on the process master and the performance, and attempts to optimize the margin time.
At a manufacturing site where there is no standard process master, the work content that the site leader instructs the workers every morning is defined as the "scheduled route."

Every morning, the site leader instructs the workers on the scheduled route, and the site workers perform the work assigned to them in accordance with the work instructions displayed on an electronic terminal such as a taplet. Register by operating the start, interrupt, resume, and end buttons on the work screen. At the time of suspension, the reason for suspension can also be registered.

The work performance collection system S is a system that automatically collects indirect time and lost time in addition to standard work time, and visualizes work progress. Work results automatically collected by the system can be used to analyze product processes using BI (Business Intelligence) tools. Note that conventionally, the ratio of slack time to standard time was analyzed as the slack rate.

FIG. 1 is a configuration diagram of a work performance analysis system in this embodiment.
The work performance analysis system S includes a site navigation server 1, an administrator terminal 3, a printer 4, and worker terminals 2A to 2C. The site navigation server 1, administrator terminal 3, and printer 4 are connected to a network N and can communicate with each other. This site navigation server 1 can be operated by an administrator such as a site leader using an administrator terminal 3 having login authority. The site leader assigns work details to each worker. The site navigation server 1 transmits the work details of each worker to the worker terminals 2A to 2C.

The worker terminals 2A to 2C are tablet terminals, for example, and can communicate with the site navigation server 1 via wireless access points 5A and 5B connected to the network N. Hereinafter, when the worker terminals 2A to 2C are not distinguished, they will simply be referred to as worker terminal 2. The worker has login authority for the worker terminal 2. The worker views the work details received from the site navigation server 1 on the worker terminal 2 and inputs the start, interruption, restart, and end of the work. The information registered by the worker is transmitted to the site navigation server 1. This allows the site navigation server 1 to collect work results.

FIG. 2 is a block diagram of the work performance analysis system.
The work execution analysis system S is configured by a site navigation server 1 and a worker terminal 2 that are communicably connected.

The site navigation server 1 is a computer equipped with a CPU (Central Processing Unit) and a memory, and includes a control section 11, a communication section 12, a database section 13, and a printer driver 14.

The control unit 11 embodies an application equipped with this site navigation function, and includes a production planning processing unit 111, a work progress processing unit 112, a requirements expansion unit 113, an instruction processing unit 114, a performance processing unit 115, and a work progress processing unit 112. A user management section 116 is provided.
The production planning processing unit 111 processes production planning at each site. The work progress processing unit 112 processes the progress of each worker.

The required amount development unit 113 develops the required amount of resources necessary for each task. This makes it possible to determine whether each task can be performed. The instruction processing unit 114 generates, registers, and confirms work instructions for the site leader, and transmits the work instructions to each worker terminal 2 through the communication unit 12. The performance processing unit 115 records the work performance of each worker in the performance database 133, and refers to this performance database 133 to total up the work performance of each worker. The worker management unit 116 manages the name, affiliation, attendance, etc. of each worker.

The communication unit 12 is, for example, an IIS (Internet Information Server), and performs communication with external devices including the worker terminal 2 operated by each worker.
The request reception processing unit 122 receives a request from an external device such as the worker terminal 2, and stores it in the request queue 123. The requests stored in the request queue 123 are output to the control unit 11. The control unit 11 performs various processes according to this request and generates a response.
The response transmission processing unit 121 transmits a response to the request to the external device.

The database unit 13 includes a database management system 131, a master database 132, a performance database 133, and a work plan database 134.
The database management system 131 is middleware that manages various databases described below. The master database 132 is a master file that stores information related to various tasks in advance. The track record database 133 is a database in which work records are registered. The track record database 133 records work information regarding the start, interruption, reason for interruption, restart, and end of work that the communication unit 12 receives from each worker terminal 2. The work plan database 134 is a database for registering and confirming the work selected by the site leader.

The work selected by the site leader is temporarily registered in the work plan database 134. When the selection of the work by the site leader is completed, the schedule is displayed as a list on the display unit (not shown) of the administrator terminal 3. Based on this schedule, the site leader finalizes the plan for the day. The instruction processing unit 114 transmits work instructions to each worker terminal 2 and registers the work plan in the performance database 133.
The printer driver 14 is a driver that outputs data to the printer 4 connected via the network N and causes the printer 4 to print.

The worker terminal 2 is configured to include a web browser section 21 that is realized by executing a browser program, and a print instruction section 25 that is realized by executing a print program. The web browser section 21 includes an operation display section 24, a request transmission processing section 22, and a response reception processing section 23.

The operation display unit 24 displays an operation screen on a touch panel display (not shown) of the worker terminal 2, and acquires user operation information, for example, operation information such as a tap or a swipe.
The request transmission processing unit 22 transmits a request generated in response to a user's operation to the site navigation server 1. The response reception processing unit 23 receives a response to this request from the on-site navigation server 1.

The print instruction unit 25 instructs the site navigation server 1 to print from the worker terminal 2 in response to a user's instruction. The printer driver 14 of the site navigation server 1 outputs print data to the printer 4 in response to this print instruction.

《Product process analysis method》
Before the morning meeting, the site leader selects today's work from the work list, creates a scheduled route, and assigns it to the workers. Each worker selects one of the assigned tasks, performs the task, and inputs the start, interruption, restart, and end of the task. Thereby, the site navigation server 1 can automatically collect work results and automatically create daily reports.

FIG. 3 is a diagram showing the configuration of the performance database 133.
Row type 0 (instruction) of the performance database 133 includes the instruction number column, status name column, item code column, item name column, planned production quantity column, unit name column, person in charge name column, overall progress column, and scheduled time ( It consists of fields (from start to end).

Row type 1 (major process) of the performance database 133 includes an instruction number column, a major process code column, a major process name column, a progress column, an actual work time column, and a standard work time column.

The row type 2 (medium process) of the performance database 133 is an instruction number column, a major process code column, a major process name column, a medium process code column, a medium process name column, a progress column, a scheduled process start date and time column, and a process start date and time. , a scheduled process end date and time field, a process end date and time field, an actual work time field, and a standard work time field.

Row type 3 (SOP) of the performance database 133 is the instruction number column, major process code column, major process name column, medium process code column, medium process name column, SOP code column, SOP name column, progress column, and actual work. It is composed of a time column, a standard work time column, a correction/absence column, a scheduled worker name column, a worker name column, an interruption time column, a restart time column, and an interruption reason column.

FIG. 4 is a diagram showing the suspension reason table 1322 stored in the master database 132.
The interruption reason table 1322 is a table that defines which of indirect man-hours, lost man-hours, and other man-hours the interruption period should be allocated to depending on the reason for interruption. This makes it possible to analyze the interruption period in more detail and use it to improve business operations.

Indirect man-hours are man-hours that indirectly contribute to work, including morning meetings, confirmation of work instructions, start-of-work inspections, meetings/meetings, education/training, 5S (sorting, tidying, cleaning, cleanliness, discipline), equipment inspections, It's cleaning. The period of indirect man-hours is included in the operating period.

Lost man-hours are man-hours that are lost and do not contribute to the work, and include machine/tool/computer failures, waiting for parts/materials, waiting for approval instructions, defect sorting (defective parts), incorrect instructions/processing (wrong drawings), customer This is a change in the circuit ordered (repair work). The period of lost man-hours is not included in the operating period and is a non-operating period.

"Other" refers to other man-hours, which is when the worker returns home or leaves the workplace for other reasons. For example, a worker may complete one work item in 2-3 days. In this case, the worker returns home after finishing the day's work even if the worker is in the middle of the work. The interruption in this case does not fall under indirect man-hours or lost man-hours, but is treated as other man-hours.

FIG. 5 is a diagram showing a current day resource table 1321 for determining whether each product can be manufactured based on the status of each task.
The current day's resource table 1321 is configured to include a current day's resource major category column, medium category column, status column, and each parts column. This day's resource table 1321 is included in the master database 132 (see FIG. 2) and is processed by the instruction processing unit 114.

The current day resource major classification column stores the name of the major resource classification required on the day of work. Here, the resource classification column for the day includes four items: parts, outsourcing partner companies, workers, and design drawing changes. The intermediate classification stores the name of the intermediate classification of resources required on the day of work.

The status column stores the presence/absence status of resources on the current day. Here, if there are resources, "0" is stored in the status column, and if there are no resources, it is blank.

The parts A column includes a parts 1 column and a parts 3 column. This indicates that in order to produce part A, parts 1 and 3 are required.
The part 1 column stores various resources necessary for producing part 1. Here, the part 1 column indicates that part 1, cooperating company A, and worker B are required, and that there is no change in the design drawing. Since all the corresponding status columns are "○", part 1 is marked with "●" and can be produced.

The same applies to the parts 3 column below. Since parts 1 and 3 included in part A can be produced, part A can also be produced.
The component B column includes a component 1 column and a component 4 column. This indicates that in order to produce part B, parts 1 and 4 are required. Since parts 1 and 4 included in part B can be produced, part B can also be produced.

The component C column includes a component 2 column and a component 3 column. This indicates that in order to produce part C, parts 2 and 3 are required. Here, the status column corresponding to part 2 is blank and cannot be produced, so part C cannot be produced. In other words, each task cannot be performed if the logical product of the situations related to each task is NG.
The instruction processing unit 114 excludes tasks that are impossible under the current resource situation from being instructed. This can prevent the site leader from erroneously instructing impossible work.

FIG. 6 is a diagram showing the work schedule content registration screen 61.
The work schedule content registration screen 61 displays a work table 611, a selection check box 614, and a work content list creation button 615. In the work table 611, a work is described in each row, and a major division column, a medium division column, and a small division column indicating the work contents are described in each column.

The selection check box 614 is, for example, a check box for the site leader to select the work to instruct each worker. Note that the selection checkbox 614 regarding component C is displayed as disabled and cannot be selected. This is because it has been determined that part C cannot be worked on based on the current day's resource table 1321 (see FIG. 5).

In the work table 611, selection checkboxes 614 relating to parts A and B in parts manufacturing, wiring and parts mounting in assembly are displayed as enabled. Furthermore, selection checkboxes 614 related to component A and component mounting are checked, indicating that these operations will be instructed to the operator.
When the work content list creation button 615 is clicked here, a scheduled route is created and this scheduled route is sent to each worker terminal 2.

FIG. 7 is a flowchart showing a process for determining whether each task can be selected.
First, the site leader inputs the status of each cause information via the administrator terminal 3 (S10). The status of each input cause information is stored in the status column of the current day's resource table 1321.

Next, the required amount expansion unit 113 of the site navigation server 1 repeats each process of steps S11 to S16 for each task in the current day's resource table 1321.
The required amount development unit 113 calculates the logical product of all the situations of all the elements constituting this work (S12). The required amount expansion unit 113 determines the logical product of all situations (S13).

In step S13, if the logical product of all the situations is NG, the requirement development unit 113 makes the work in question unselectable today (S14), and proceeds to step S16. If the logical product of all the situations is OK, the requirements expansion unit 113 makes the work in question available for selection today (S15), and proceeds to step S16.

Next, the requirements expansion unit 113 determines whether all the tasks in the current day's resource table 1321 have been repeated (S16). If there is any work that has not yet been repeated, the required amount development unit 113 returns to the process of step S11, and if all the work has been repeated, the process of FIG. 7 ends.

After determining the scheduled route (S20), the site navigation server 1 transmits instruction information to each worker terminal 2A, 2B (S21). This instruction information refers to the determined scheduled route.

The worker operates the worker terminal 2A, selects a process (work) from the instruction list (S22), and registers the start of that process (work). Thereby, the worker terminal 2A transmits the start time information to the site navigation server 1 (S23). The site navigation server 1 records this process and start time in the performance database 133 (S24).

When interrupting work, the worker operates the worker terminal 2A to register the interruption and the reason. Thereby, the worker terminal 2A transmits the interruption time information and the reason to the site navigation server 1 (S25). The site navigation server 1 records the interruption time and reason for this process in the performance database 133 (S26).

When restarting work, the worker operates the worker terminal 2A to register the restart. Thereby, the worker terminal 2A transmits restart time information to the site navigation server 1 (S27). The site navigation server 1 records the restart time related to this process in the performance database 133 (S28).

When finishing the work, the worker operates the worker terminal 2A to register the completion. Thereby, the worker terminal 2A transmits end time information to the site navigation server 1 (S29). The site navigation server 1 records the end time of this process in the performance database 133 (S30).

The site navigation server 1 creates a daily work report based on the performance database 133, and prints the daily work report (S31). Furthermore, the on-site navigation server 1 aggregates the results from various viewpoints based on the results database 133 (S32).

FIG. 13 is a diagram showing a planned route 81 and a work record 82.
The scheduled route 81 includes a scheduled work order determined every morning and its work items. Currently, the site leader gives instructions to the workers before starting work every morning. This work instruction will be the latest and final route.
Since the scheduled route 81 is recorded every day, it is possible to know when and what instructions were given when the product is completed. This history is used as a process master for product process analysis.
The site navigation server 1 displays a scheduled route 81 as a work plan and a work record 82 so that they can be compared. This makes it possible to manage the manufacturing process on a product-by-product basis. Process analysis is possible by collecting and comparing work results according to the planned route created for each product work item.

FIG. 15 is a flowchart for displaying performance bars of work items in different colors.
The performance processing unit 115 of the site navigation server 1 repeats the processing of steps S50 to S55 from the start to the end of a certain item. Next, the performance processing unit 115 determines the period within this item (S51).

In step S51, if the period in this item is from start to interruption, restart to interruption, restart to end, or start to end, the performance processing unit 115 proceeds to step S53 and adds this period to the operating period. (S53). In step S51, if the period in this item is restarted from the interruption, the performance processing unit 115 proceeds to the process in step S52.
In step S52, the performance processing unit 115 determines the type of this interruption period (see FIG. 4). The type of period is determined depending on the reason for interruption.

In step S52, the performance processing unit 115 proceeds to step S53 if the type of interruption period is indirect man-hours, proceeds to step S54 if it is lost man-hours and adds it to the non-operating period, and if it is other man-hours, proceeds to step S55. .

In other words, the performance processing unit 115 determines the period of standard work man-hours from the work information related to each work item, and determines the interruption period as either indirect man-hours or lost man-hours depending on the reason for the interruption during the interruption period. do. This allows the site navigation server 1 to perform quantitative evaluation by analyzing the collected results.

In step S55, the performance processing unit 115 determines whether or not the item has been repeated from the start to the end. The performance processing unit 115 returns to step S50 if the process has not been repeated until the end, and proceeds to step S56 if the process has been repeated until the end.
The performance processing unit 115 displays the total results of the items on the performance bar 712 (FIG. 16) (S56), and ends the process of FIG. 15.

Using this work man-hour display screen 71, the site leader can compare the expected route, which is the work plan, with the work results, and can manage the manufacturing process on a product-by-product basis. Specifically, the site navigation server 1 automatically collects the results for each work item from the worker terminal 2, performs quantitative evaluation through product process analysis, and visualizes wasteful work. Thereby, the work execution analysis system S can grasp the true production capacity and improve productivity through appropriate working hours. Furthermore, the work execution analysis system S can reduce loss of order opportunities and improve profits by reducing production costs such as overtime and outsourcing expenses.

FIG. 17 is a flowchart for displaying worker performance bars in different colors.
The performance processing unit 115 of the site navigation server 1 repeats the processing of steps S70 to S75 for the period of each item for one day of the worker. Next, the performance processing unit 115 determines the period within this item (S71).

In step S71, if the period in the item for this worker is from start to interruption, restart to interruption, restart to end, or start to end, the performance processing unit 115 proceeds to step S73 and sets this period to operation. It is added to the period (S73). In step S71, if the period within this item is resumed from the interruption, the performance processing unit 115 proceeds to the process of step S72.
In step S72, the performance processing unit 115 determines the type of this interruption period. The type of period is determined depending on the reason for interruption.

In step S72, the performance processing unit 115 proceeds to step S73 if the type of interruption period is indirect man-hours, proceeds to step S74 if it is lost man-hours and adds it to the non-operating period, and if it is other man-hours, proceeds to step S75. .
In other words, the performance processing unit 115 determines the period of standard work man-hours from the work information related to each worker, and determines this interruption period as either indirect man-hours or lost man-hours depending on the reason for interruption during the interruption period. do. This allows the site navigation server 1 to perform quantitative evaluation by analyzing the collected results.

The performance processing unit 115 determines whether the period of each item for one day of the worker has been repeated. If the performance processing unit 115 has not yet repeated all the steps, the process returns to step S70, and if all the steps have been repeated, the process proceeds to step S76.

In step S76, the performance processing unit 115 calculates the worker's operating rate. The performance processing unit 115 displays the total results of the items on the performance bar 722 (FIG. 18) (S77), and ends the process of FIG. 17.

FIG. 18 is a diagram showing worker A's performance bar 722.
On the left side of this work man-hour display screen 72, the worker's name is written as "Worker A", and further, "Operating rate = 70%" is written. Further, on the work man-hour display screen 72, a planned route bar 721, an actual result bar 722, and a legend 723 are displayed. The scheduled route bar 721 indicates a work period for worker A from 9:00 to 17:00 on a certain day. The performance bar 722 shows the performance of worker A in chronological order. A legend 723 indicates the meaning of the coloring of the performance bar 722.

A site leader or the like can refer to the work man-hour display screen 72 and compare the work results of each worker to manage the manufacturing process on a product-by-product basis. Furthermore, although the work man-hour display screen 72 displays the daily operating rate, the present invention is not limited to this, and the worker's operating rate can be displayed on a weekly or monthly basis.

FIG. 20 is a graph showing the operating rate of each site. The vertical axis of the graph indicates the operating rate of all workers belonging to the site (office). The horizontal axis indicates each site. By displaying the relationship between the operating rate and the worker and the relationship between the operating rate and the site in a graph in this way, it is possible to easily identify the worker or site that should be improved.

FIG. 21 is a graph showing the operating rate deviation of each worker in order. The vertical axis of the graph indicates the worker's operating rate deviation. The horizontal axis indicates each worker. Workers on the left side of the graph have a larger difference from the average. Workers on the right side of the graph have smaller differences from the average.

FIG. 22 is a graph showing the operating rates of all workers belonging to each site in order of deviation. The vertical axis of the graph indicates the operating rate deviation of all workers belonging to the site (business operator). The horizontal axis indicates each site. Sites on the left side of the graph have larger differences from the average. Sites on the right side of the graph have smaller differences from the average.

By displaying the relationship between the operating rate and the worker and the relationship between the operating rate and the site in order of deviation in this way, it is possible to more clearly identify the worker or site that should be improved.
Note that the graph output by the system is not limited to this, and may be a graph comparing the schedule and actual results for each work item for each product.

The horizontal axis indicates work items or products. In this graph, the planned route (time) for each work item or product is displayed in a bar graph, and the actual results are displayed in a bar graph superimposed on this.

The margin rate in the ME method is expressed as standard time/net working time. However, we would like to evaluate the margin of production period Tm with respect to standard time Ts. Therefore, the margin is defined as Y and defined in equation (1).

Below, the margin Y for the specification N of the device M will be calculated.
If the actual production period is 75 days and the working hours per day are 8 hours, the production time Tm is 600 hours.
Here, by totaling the working time from the common work list of the specification N of the device M, the total working time, that is, the standard time Ts can be calculated. Here, it is assumed that the production time Ts is 292 hours.
The margin is calculated using equation (2). The margin at this time is approximately 2.05 times.

FIG. 24 is a graph showing margins for each work item/product. The vertical axis of the graph shows the degree of margin. The horizontal axis of the graph indicates work items or products.
In this way, the margin Y of a work item or product can be calculated by setting the time of the scheduled route as the standard time Ts, and summing up the time related to the performance of the work item or product and setting it as the production time Tm. By displaying this in a graph, a site leader or the like can easily determine whether the margin of work item or product is appropriate.
