BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[System configuration]
FIG. 1 is a block diagram showing the configuration of an information processing system S including a server 1 according to an embodiment of an information processing apparatus of the invention.
The information processing system S shown in FIG. 1 is configured to include at least a server 1 , an administrator terminal 2 and a field terminal 3 . The server 1, the administrator terminal 2, and the field terminal 3 are interconnected via a network N such as the Internet.

The server 1 is a server that manages each operation of the manager terminal 2 and the site terminal 3, and executes various processes for providing a process management service (hereinafter referred to as a "small lot scheduler"), which will be described later.
The administrator terminal 2 is an information processing device operated by an administrator M who manages the production of products, and is composed of, for example, a smart phone or a tablet.
The site terminal 3 is an information processing device operated by the worker W at the production site, and is configured by, for example, a smart phone or a tablet.
Note that the number of the administrator terminal 2 and the field terminal 3 shown in FIG.
Specific contents of the functions provided in each of the server 1, the administrator terminal 2, and the field terminal 3 shown in FIG. 1 will be described later with reference to FIG.

Next, an overview of the small lot scheduler provided by the information processing system S of FIG. 1 will be described with reference to FIG.

[Small lot scheduler]
FIG. 2 is a diagram showing an overview of the small lot scheduler.

The small lot scheduler is a tool that assists the service that enables efficient progress management by sharing production plans for small lot products, especially among products, between the manager M and the worker W. is.
Here, the production plan means a plan regarding the production quantity and production period of the product. The product here is a broad concept that includes not only final products to be provided to consumers, but also products produced in a given process to be provided to the next process (for example, parts in terms of final products).
That is, the production plan refers to a plan that determines which product and how much to produce within a predetermined period. The production plan can be roughly divided into two. One is a plan for the entire production period (hereinafter referred to as "long-range production schedule"), and the other is a work plan for one or more machines and equipment and one or more personnel required for production (hereinafter " (referred to as the equipment personnel work plan).

As shown in FIG. 2, the small lot scheduler includes the preparation of quotations, production plans, work instructions, and material arrangements performed by manager M, and performed by worker W at the production site. Assists in the processing, inspection, and shipment of products
Specifically, for example, when information about a production plan or information about work instructions is input based on the operation of the manager M, the input contents are shared with the worker W via the server 1 . Further, based on the operation of the worker W, information on production results is input, and information on progress management, information on delivery date management, and information on cost management are output based on the input contents.

The small lot scheduler has versatility that can handle all kinds of products. By introducing the small lot scheduler to the management department to which the manager M belongs and the manufacturing department to which the worker W belongs, the manager M and the worker W have advantageous effects in the following works, for example. can enjoy

(Creation of quotation)
Conventional manager M, when creating a quotation, first designs all the processes necessary to produce the product based on the product drawing, and then prepares this on paper as a process plan. was output. The output process plan is sequentially circulated to the worker W in charge of each processing step, and the delivery date for each process is entered by the worker W in charge of each processing step. After circulating the process plan, the manager M created an estimate sheet while looking at the process plan in which the delivery date of each processing process was entered.
In this way, when a conventional manager prepares an estimate by the conventional method, the process plan output on paper is circulated, and the estimate is made based on the information such as the delivery date entered in each processing process at the time of circulation. It was time consuming to write a book.
On the other hand, when a small lot scheduler is introduced, information on orders (hereinafter referred to as "order information") and information on processes and man-hours required for product production (hereinafter referred to as "product information") Based on such information, a quotation is automatically created. Here, the worker W in charge of each processing process can operate the site terminal 3 and input the delivery date of the process he/she is in charge of, so that the work of outputting and circulating the process plan on paper can be eliminated. . As a result, the time cost required for the manager M's input work can be reduced.

(Preparation of work instructions)
In addition, when the conventional manager M issues a work instruction to the worker W, the manager M decides the specific work content in each processing step while looking at the contents of the estimate written by him/herself. A work instruction was created by entering the contents.
In this way, when the work instruction is issued by the conventional method, the manager M has to create the work instruction by re-entering the contents described in the created estimate.
On the other hand, when a small lot scheduler is introduced, the contents described in the quotation are automatically reflected in the work instructions, so the manager M can avoid duplicate input work. . In addition, when there is no need to create an estimate sheet, a work instruction sheet is automatically created based on information such as order information and product information. As a result, the time cost required for the manager M's input work can be reduced.

(Preparation of production plan)
Further, conventionally, when creating a production plan for each process, the manager M determines a specific production plan for each processing process while looking at the contents of the work instructions. Specifically, the names of parts to be produced, the number of parts to be produced, the number of personnel to be assigned, and the like for each mechanical facility that operates in each machining process were determined as a production plan. The production plan is written on a whiteboard or the like installed at the production site and transmitted to the worker W, and the worker W performs the work according to the production plan written on the whiteboard or the like.
In this way, when creating a production plan using the conventional method, the production plan created based on the content of the created work instructions can be written on a whiteboard or the like installed at the production site. The trouble of notifying the person W had arisen.
On the other hand, when a small lot scheduler is introduced, a production plan is automatically created based on information such as order information and product information, and the contents thereof are output to the field terminal 3 in real time. Therefore, the worker W can easily acquire the content of the created production plan via the field terminal 3 . Thereby, the time cost required for the input (entry) work of the manager M can be reduced.

(Creation of production results)
Conventionally, the manager M created production results while looking at duplicated work results described in two documents, a daily report and a work instruction, which were created in each processing step.
In this way, when creating work results by the conventional method, in each processing step, the work results with overlapping contents are described in two documents, the daily report and the work instruction sheet. In addition, since the manager M needs to compile and tally reports on the work results for each processing step, it is impossible to manage the relationship between the production results and the delivery date for each processing step in real time.
On the other hand, when a small lot scheduler is introduced, the work results input (description) work in each processing process is simplified, so the work results with overlapping contents in the two documents, the daily report and the work instruction sheet is described. In addition, it is possible to manage in real time the relationship between the production results and the delivery date for each processing step. As a result, the time cost required for input work can be reduced.

In this way, according to the small lot scheduler, the side managing the production results and the production site can share the production results in real time while simplifying the work of inputting the production results on the production site side.
In other words, redundant input work by the manager M and the person W in charge of each processing process can be abolished. It is also possible to reduce it further. In terms of costs, assuming that the number of processes is 5 and the labor cost per hour is 3600 yen, it is possible to reduce 7800 yen per case.
In addition, the production plan is so-called "visualized" and shared between the manager M and the worker W in real time. As a result, the operating rate can be improved according to the operating status. Furthermore, since it is possible to deal with delays in delivery at an early stage, it is possible to prevent delays in delivery.

Next, the flow of the small lot scheduler in FIG. 2 will be described with reference to FIG.

FIG. 3 is a flow chat showing the flow of the small lot scheduler.

As shown in FIG. 3, when there is an inquiry about a certain product X, an estimate sheet and a plan for combining one or more processing processes (hereinafter referred to as a "process plan") are generated based on the predetermined quotation conditions indicated in the inquiry. ) is created. When the customer approves the contents of the written estimate and the process plan, an order for the production of the product X is received.
On the other hand, if there is no inquiry and the order is placed immediately, the order for production of the product X is accepted as it is.

If the product X for which production is ordered has a repeat product number (reordered product number), the presence or absence of inventory is confirmed, and if there is inventory, an inspection is performed before shipment. On the other hand, if there is no product X in stock, a process plan that has been created is called up, and a work instruction sheet is created for each order based on the called up process plan. A work instruction sheet is created through the creation of two stages of planning, namely, a long-term production schedule and an equipment personnel work plan.
If the product X has a new product number instead of a repeat product number (reordered product number), a new process plan is created, and a work instruction is created based on the created process plan.

When the work plan is created, inventory of materials required for each processing step is checked. If there is inventory of materials for each processing step, the work in each processing step is executed. On the other hand, if the stock of materials in each processing step is insufficient, the work in each processing step is executed after ordering the materials and receiving the delivered materials.

In each processing step, registration of actual production results and registration of progress are performed. The manufactured product X is inspected before shipment. For processes that require outsourcing, pre-shipment inspections are conducted after placing an order and receiving the delivered outsourced products.

When the product X is inspected before shipment, the contents of the inspection are recorded. After that, when the product X is shipped, the contents of the shipment are recorded.

Next, in the flowchart of FIG. 3, the details of the "internal manufacturing process" and "registration of actual production results" enclosed by dashed lines will be described with reference to FIG.

FIG. 4 is a diagram showing the details of the "in-house manufacturing process" and "registration of actual production results" enclosed by dashed lines in the flowchart of FIG. "In-house manufacturing process" and "registration of actual production results" enclosed by dashed lines correspond to processing executed in step S4 in FIG. 8, which will be described later.

A production plan created to produce product X is composed of a combination of one or more processing steps. FIG. 4(A) shows an example of a combination of one or more machining processes forming a production plan that is a combination of an NC lathe process, a 5-axis machining center process, and a carburizing and quenching process.
Here, as shown in FIG. 4B, the small lot scheduler performs (1) setup start, (2) setup end, (3) machining start, and (4) for each of one or more machining processes. ) It is possible to manage the actual production results by transitioning between the four states of machining completion.
That is, in the example shown in FIG. 4A, the small lot scheduler performs (1) setup start, (2) setup The production performance can be managed by four state transitions of end, (3) start of processing, and (4) end of processing.
These four state transitions can be used as a common concept in any processing process. Therefore, the small lot scheduler is a versatile service that can be used in all product processing processes regardless of the field.

In summary, by introducing a small lot scheduler, it is possible to formulate work instructions in two stages: large schedule production planning and equipment personnel work planning.

In addition, as a supplement to FIG. 3, in manufacturing, it is necessary to associate the product with the information. The work order goes through the manufacturing process together with the material and the work in process. For outsourced items, a purchase order is issued based on the work instructions, and the product and delivery note are received together to go through the processing process. Regarding the movement of money, order items are checked against the work order → shipping list with the order list, ordered items are checked against the purchase order → delivery note, and each is linked to billing/payment. In the example of FIG. 3, the bill payment flow has been omitted.

Also, by introducing the small lot scheduler, the following effects can be obtained. In other words, in process control in manufacturing, it is important how to obtain real-time production results for a production plan and utilize them for progress management and problem detection. Conventionally, real-time process control has been implemented in some mass-production models, but it has not been standardized in small-lot models. In this respect, by introducing a small lot scheduler, confirmation of production plans and collection of results can be input/reflected in real time with a tablet or the like (administrator terminal 2 or site terminal 3) or the like.
Note that the administrator terminal 2 and the field terminal 3 do not need to be tablets or the like, and can be configured as IoT devices that do not require one-touch operation. In this case, it becomes possible to automatically collect results.

Although not shown, the administrator terminal 2 and the site terminal 3 in the information processing system of FIG. 1 also have the hardware configuration shown in FIG. However, the administrator terminal 2 and the field terminal 3 have touch panels as the output unit 16 and the input unit 17 when configured by a smart phone or a tablet.

[Functional configuration]
FIG. 6 is a functional block diagram showing an example of the functional configuration of the server 1 of FIG. 5 that implements the business support processing and its sub-processing.

Here, the business support process is a series of processes for realizing the above-described small lot scheduler, and is composed of various sub-processes such as basic information registration process, production plan creation process, and production result registration process. By executing the business support processing, it is possible to solve problems such as duplicate input and scattered information, so that it is possible to centrally manage information related to production in real time.

As shown in FIG. 6, in the CPU 11 of the server 1, the registration accepting unit 101 functions when the basic information registration process is executed among the sub-processes. Also, when the production plan creation process is executed, the plan creation unit 102 functions. Further, when the actual production record registration process is executed, the actual record management unit 103, the actual record calculation unit 104, and the display control unit 105 function.
In one area of the storage unit 18, a registration information DB 401, a production plan DB 402, and a production performance DB 403 are provided.

The registration accepting unit 101 accepts information (hereinafter referred to as “user information”) necessary for registering a user who intends to use the small lot scheduler. The received user information is stored and managed in the registration information DB 401 . User information is thereby registered in the small lot scheduler. Here, who the user is is not particularly limited. For example, company C to which manager M and worker W in FIG. 1 belong is an example of a user. Moreover, what information is included in the user information is not particularly limited. For example, the user information may include e-mail address, login ID and password, company name as contact information, address, telephone number, FAX number, name of person in charge, coupon code for using the small lot scheduler at a discount price, etc. can.

Further, the registration reception unit 101 receives basic information of users who use the small lot scheduler. The accepted basic information is stored and managed in the registration information DB 401 . The basic information is thereby registered in the small lot scheduler. Such registration processing is hereinafter referred to as “basic information registration processing”.
What information is included in the user's basic information is not particularly limited. For example, company information, factory information, department information, supplier information, process information, personnel information, etc. can be included.

Specifically, the company information includes information on operating hours and operating days for each company. By registering information on operating hours and working days for each company, when production plans are automatically created, manual work (such as setup work) can be kept within the operating days and regular hours for each company. be able to.

The factory information includes the name of the factory and information on operating hours and working days for each factory. By enabling registration on a factory-by-factory basis, it becomes possible to create and confirm a production plan for each factory.

The department information includes department name, affiliation, and information on operating hours and working days for each department. By enabling registration on a department-by-department basis, it becomes possible to create and confirm a production plan for each department.

The supplier information includes supplier name, management number, business relationship, and information on outsourced processes. Information on the supplier can be registered together with the preparation of the quotation or the preparation of the work order. It is also possible to automatically create a list of registered business partners.

The process information includes, as information on equipment and work, information on the factory to which the worker belongs, the department to which the worker belongs, the process classification, the process control number, the name of the process, the unit price per hour, and the representative for each process. If the process category (for example, "cutting") is the same between processes, the production plan may be distributed. The unit price per hour can be used in cost accounting based on production plans and actual production results.

The personnel information includes information on the person in charge W, the factory to which the worker belongs, the department to which the worker belongs, the unit price per hour, the process in charge, the presence or absence of administrator authority, the log-in history, and the like. Since the presence of personnel is a prerequisite for production, it is possible to prevent processes that are not associated with personnel from being reflected in the production plan. Since the information on personnel includes personal information, only the manager M may be allowed to view, edit, and create a production plan. The unit price per hour can be used in cost accounting based on production plans and actual production results.

The plan creating unit 102 creates a production plan consisting of a combination of one or more processing steps for producing a product. Hereinafter, such creation processing will be referred to as "production plan creation processing".
Specifically, the plan creation unit 102 creates a production plan that consists of a combination of one or more processing steps based on order information, product information, and various types of information (user information, basic information) stored in the registration information DB 401. create a plan; The created production plan is stored in the production plan DB 402 and managed.
Here, the order information includes information such as the product name, product number, quantity, order recipient, etc. of the ordered product. In addition, the product information includes information such as process classification, setup time, processing time, worker W, material, quantity, and delivery date.
It should be noted that the production plan created by the plan creating unit 102 can be edited by an input operation to the manager terminal 2 .

In addition, when the inventory quantity of the product is managed by the inventory management unit 106, which will be described later, the plan creation unit 102 creates a production plan for the product based on the inventory quantity managed by the inventory management unit 106. be able to.

In addition, when the order quantity of products is managed by the order management unit 107, which will be described later, the plan creation unit 102 creates a production plan for the product based on the order quantity managed by the order management unit 107. be able to.

In addition, the plan creation unit 102 can execute control to present one or more combinations that can be used in the short schedule corresponding to the large schedule of the manufacturing process. Specifically, the plan creation unit 102 registers in advance combinations of necessary mechanical equipment and workers W for all of one or more processing steps that are components of the production plan. After that, when a long schedule production plan is created with the name of the manufacturing process that is a constituent element of the production plan, a screen on which one or more machines and equipment and one or more personnel required for creating the equipment personnel work plan can be selected. is displayed on the field terminal 3.
As a result, the manager M can create a long-term production plan without worrying about resource allocation in the equipment personnel work plan. In addition, the person in charge W (for example, the person in charge of the processing site) selects only one or more processing steps that are the target of the equipment personnel work plan to be planned by himself/herself, and concentrates on creating the equipment personnel work plan. be able to.

The information required when creating a production plan is not particularly limited. For example, as information about an order, the classification of whether it is an estimate or a work order, the management number of the order, the name of the business partner, the factory or department of the delivery destination, the number that distinguishes the product, the name that distinguishes the product, the delivery requested by the customer Information such as the number of pieces, scheduled production start date, final delivery date of the production plan, delivery date for each process, production factory, etc. can be included. In addition, as information about the product, the product number, product name, the order of the product production process, the classification of each processing process, the name of the equipment, the name of the person in charge of each process, the setup time of each processing process (time required for human work), Information such as the processing time of each processing step (the time the machine is running), the material and dimensions of the product, etc. can be included.

Moreover, the specific content of the production plan is not particularly limited. For example, as shown in FIG. 7, a production plan may be created so that the details of an order received, a product, one or more processes, materials, and one or more personnel are linked. A plurality of personnel (workers W) may be arranged for each process. As a result, it is possible to appropriately replace the workers W, so that it is possible to create a flexible production plan that conforms to reality. Also, the output format of the production plan is not particularly limited, and the production plan may be output for each month, week, date and time, for each process, for each person in charge, and the like.

The performance management unit 103 manages the production performance for each of one or more machining processes by changing four states: setup start, setup end, machining start, and machining end. Specifically, the performance management unit 103 receives an input operation to the field terminal 3 in each of the four states of the start of setup, the end of setup, the start of machining, and the end of machining for each machining process. Triggered by the reception of this input operation, the result management unit 103 acquires information about the date and time of each of these four states. The acquired date and time information is stored and managed in the production performance DB 403 . As a result, information on the dates and times of the four states is registered in the small lot scheduler. Hereinafter, such registration processing will be referred to as "production result registration processing".
Here, the specific mode of the input operation to the field terminal 3 is not particularly limited, but in this embodiment, as shown in FIG. making it possible to obtain
As a result, it is possible to simplify the work of inputting the actual production results on the production site side.

The actual result calculation unit 104 calculates the actual production result for the production plan based on the date and time of each of four states: the start of setup, the end of setup, the start of machining, and the end of machining. Specifically, the result calculation unit 104 calculates the date and time of each of the four states of the start of setup, the end of setup, the start of machining, and the end of machining of each process acquired by the result management unit 103. Then, the actual production results for the production plan for each process are calculated.
As a result, the date and time at the time of the input operation can be acquired by a simple input operation to the field terminal 3, so the actual result calculation unit 104 calculates the detailed production result by comparing with the number of production pieces that are continuously counted separately. can do.

The display control unit 105 executes control to display information related to the production plan and information related to the actual production results on the manager terminal 2 or the field terminal 3 . Specifically, for example, the display control unit 105 sends the production plan created by the plan creating unit 102 and the actual production results calculated by the actual result calculation unit 104 to the manager terminal 2 and the field terminal 3 according to the progress. In response, control for identification display is executed. In addition, the specific method of identifying and displaying according to the progress is not particularly limited. For example, when a delay in delivery occurs, the color of the Gantt chart automatically changes, and the manager M and the worker W may share this situation.
As a result, the manager M and the worker W can confirm and share the production results against the production plan in real time, so that any delay in the delivery date can be detected at an early stage. As a result, it becomes possible to prevent delays in the delivery date, so that reliability from customers can be improved.

The inventory management unit 106 manages the inventory quantity of products. Specifically, the inventory management unit 106 manages the inventory quantity of the product based on the actual production record stored in the production performance DB 403 and the quantity of the product actually shipped.
As a result, the plan creation unit 102 can create a production plan for the product, taking into consideration the inventory quantity managed by the inventory management unit 106 .

The order management unit 107 manages the order quantity of products. Specifically, the order management unit 107 manages the order quantity stored in the production planning DB 402 .
As a result, the plan creation unit 102 can create a production plan for the product, taking into consideration the order quantity managed by the order management unit 107 .

The reading unit 301 reads a predetermined identifier, and records the date and time when reading of the predetermined identifier being read becomes impossible. Specifically, for example, when the work instruction is placed at a readable position, the reading unit 301 immediately reads the QR code (registered trademark) attached to the work instruction, and the work instruction is placed. read the date and time as the date and time of the setup start. Then, when the reading unit 301 becomes unable to read the QR code (registered trademark) of the work instruction, the reading unit 301 acquires the date and time when it became unreadable as the processing end date and time. In other words, the worker W can obtain the date and time when the processing is finished simply by physically moving the work instruction sheet from a readable position to a position where it cannot be read.

Next, with reference to FIG. 8, the flow of various processes executed by the server 1 having the functional configuration of FIG. 6 will be described.
FIG. 8 is a flowchart for explaining the flow of business support processing executed by the server 1 of FIG.

As shown in FIG. 8, the server 1 executes the following series of processes.
In step S1, the registration reception unit 101 receives information of a user who intends to use the small lot scheduler.
In step S2, the registration reception unit 101 executes basic information registration processing, which is a sub-processing of the business support processing. A detailed flow of the basic information registration process will be described later with reference to FIG.
In step S3, the plan creation unit 102 executes production plan creation processing, which is a sub-process of the business support processing. A detailed flow of the production plan creation process will be described later with reference to FIG.
In step S4, the performance management unit 103 executes production performance registration processing. A detailed flow of the actual production record registration process will be described later with reference to FIG.
With this, the business support processing ends.

FIG. 9 is a flowchart for explaining the basic information registration process among the sub-processes that constitute the business support process executed by the server 1 in FIG.

In each of steps S21 to S26, the registration accepting unit 101 accepts input of user's company information, factory information, department information, supplier information, process information, and personnel information. Specifically, since user registration is performed on a company-by-company basis, an administrator M who serves as a point of contact for the user (company) operates the administrator terminal 2 to input such information, and the registration reception unit 101 receives the information. Accept input content.
In step S27, the registration reception unit 101 determines whether or not all of the essential information for registering the basic information has been received. Here, which information is essential information is not particularly limited. For example, three pieces of information, ie, the company information received in step S21, the process information received in step S25, and the staff information received in step S26, may be essential information.
If all the essential information has been received, it is determined as YES in step S27, and the process proceeds to step S28.
On the other hand, if all the essential information has not been received, it is determined as NO in step S27, and the process is returned to step S21. That is, the processes of steps S21 to S26 and the determination process of step S27 are repeatedly executed until YES is determined in step S27.
In step S28, the registration reception unit 101 registers the various information received in steps S21 to S26 as basic information.
This completes the basic information registration process, and the process returns to the flowchart of FIG.

FIG. 10 is a flowchart for explaining the flow of the production plan creation process among the sub-processes constituting the business support process executed by the server 1 of FIG.

In step S31, the plan creation unit 102 receives order information.
In step S32, the planning unit 102 receives product information.
In step S33, the plan creation unit 102 determines whether or not all of the order information and product information have been received.
If all the order information and product information have been received, it is determined as YES in step S33, and the process proceeds to step S34.
On the other hand, if all the order information and product information have not been received, it is determined as NO in step S33, and the process is returned to step S31. That is, the processes of steps S31 and S32 and the determination process of step S33 are repeatedly executed until YES is determined in step S33.
In step S34, the plan creating unit 102 creates a monthly production plan.
In step S35, the plan creating unit 102 creates a weekly production plan.
As a result, the production planning process ends, and the process returns to the flow chart of FIG.

FIG. 11 is a flowchart for explaining the flow of the actual production record registration process among the sub-processes constituting the business support process executed by the server 1 of FIG.

In step S41, the performance management unit 103 accepts selection of a production plan. Specifically, the performance management unit 103 receives an operation of selecting one production plan from among one or more production plans displayed on the manager terminal 2 or the field terminal 3 .
In step S<b>42 , the display control unit 105 performs control to display the received process information of one production plan on the manager terminal 2 or the field terminal 3 .
In step S43, the performance management unit 103 receives input operations to the field terminal 3 in each of the four states of the machining process setup start, setup end, machining start, and machining end. Triggered by the reception of this input operation, the result management unit 103 acquires information about the dates and times of these four states.
In step S44, the actual result calculation unit 104 calculates each process based on the date and time of each of the acquired four states of the start of setup, the end of setup, the start of machining, and the end of machining of each machining process. Calculate the actual production against the production plan.
In step S<b>45 , the display control unit 105 executes control to display the calculated production performance on the manager terminal 2 or the field terminal 3 .
In step S46, the performance calculation unit 104 accepts editing of the production performance displayed on the manager terminal 2 or the field terminal 3 as necessary. The display control unit 105 executes control to display the edited production results on the manager terminal 2 or the field terminal 3 .
In step S47, the performance management unit 103 registers the calculated production performance or the production performance edited as necessary in the small lot scheduler. Specifically, the performance management unit 103 stores and manages the calculated production performance or the production performance edited as necessary in the production performance DB 403 .
As a result, the actual production record registration process ends, and the process returns to the flowchart of FIG.

Next, a specific example of input operation to the site terminal 3 in the production record registration process shown in FIG. 11 will be described with reference to FIG.
12A and 12B are diagrams showing a specific example of an operation for inputting production results to the field terminal 3. FIG.

FIG. 12(A) shows an example of a screen displayed on the site terminal 3 at the start of setup in one machining process. As shown in FIG. 12(A), detailed information of the process is displayed on the field terminal 3, and a setup work start button B1 is displayed in the display area F1. The worker W presses the setup work start button B1 at the timing of starting the setup work. The performance management unit 103 receives an operation of pressing the setup work start button B1. Then, the result management unit 103 acquires information about the date and time at that point in time by using the reception of this pressing operation as a trigger. The acquired date and time information is stored and managed in the production performance DB 403 . As a result, information about the date and time of starting the setup work is registered in the small lot scheduler.

FIG. 12(B) shows an example of a screen displayed on the field terminal 3 at the end of setup in one machining process. As shown in FIG. 12(B), detailed information of the process is displayed on the field terminal 3, and a setup work end button B2 is displayed in the display area F1. The worker W presses the setup work end button B2 at the timing of finishing the setup work. The performance management unit 103 receives an operation of pressing the setup work end button B2. Then, the result management unit 103 acquires information about the date and time at that point in time by using the reception of this pressing operation as a trigger. The acquired date and time information is stored and managed in the production performance DB 403 . As a result, the information on the date and time of completion of the setup work is registered in the small lot scheduler.

In this way, by pressing a predetermined button at the timing of the start of setup and the end of setup in one machining process, each date and time can be acquired. The date and time of the start of processing and the end of processing are also acquired in the same manner. That is, the worker W presses a machining operation start button (not shown) when starting the machining operation, and presses a machining operation end button (not shown) when finishing the machining operation.

Next, a specific example of production results managed by pressing a predetermined button shown in FIG. 12 will be described with reference to FIGS. 13 and 14. FIG.
FIG. 13 is a diagram showing a specific example of production results displayed on the manager terminal 2 and the field terminal 3. As shown in FIG.

The administrator terminal 2 and the site terminal 3 can display detailed information on the production results registered by the production results registration process in real time. Specifically, as shown in FIG. 13, setup time (minutes), total processing time (minutes), material unit price (yen), number of pieces, number of defects, previous process completion date and time, setup start date and time, setup end The management terminal 2 and the field terminal 3 can display planned values and actual values for the date and time, setup stop time, machining start date and time, machining end date and time, machining stop time, and next process start date and time, and items to be transferred.

The production results displayed on the manager terminal 2 and the field terminal 3 are corrected and re-registered by pressing the "re-register result" button B3 and the "restore" button B4 displayed in the display area F2. You can also As a result, even if the setup work start button B1, the setup work end button B2, or the like is forgotten or pressed by mistake, it is possible to make appropriate corrections.

FIG. 14 is a diagram showing a specific example of the progress status of actual production displayed on the manager terminal 2 and the field terminal 3. As shown in FIG.

The manager terminal 2 and the field terminal 3 can display in real time the progress of the production record registered by the production record registration process. Specifically, as shown in FIG. 14A, it is possible to display in real time the production schedule for each item distinguished by order number, item number, and item name.

As in the example shown in FIG. 14(A), it is possible to identify and display according to the progress of the process, such as a completed process being indicated by a solid band and an unexecuted process being indicated by a hatched band. can. Furthermore, for example, a process indicated by a moving diagonal line is in progress, a process indicated by a stopped diagonal line is suspended, and a process with a blinking red edge is behind the production plan. Bands can also be identified. As a result, the manager M and the person in charge W can grasp the progress at a glance, so that delays in delivery can be prevented.

Also, detailed information on the production results for each project can be displayed on the manager terminal 2 and the field terminal 3 in real time. Specifically, as in the example shown in FIG. 14B, it is possible to display detailed information on actual production results in units of work instructions (that is, in units of orders received). Detailed information on production results includes, for example, order number, order recipient, destination, product number, product surface, setup time for each process, processing time, person in charge, material (material dimensions), material unit price, subcontract unit price, number of non-defective products, Information such as the number of defective products, cost, delivery date, total time required for processing, unit cost, and estimated cost can be included.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within the scope of achieving the object of the present invention are included in the present invention. be.

For example, in the above-described embodiments, it is described that the technology is intended for the production of small-lot products. It is nothing more than a special mention of Therefore, not only small-lot products but also medium-lot and large-lot products may be used.

Further, in the above-described embodiment, the performance management unit 103 receives input operations to the field terminal 3 in each of the four states described above, and uses this as a trigger to acquire information regarding the date and time of each of these four states. However, other methods can be used to obtain production results. For example, based on the reading state of the predetermined identifier by the reading unit 301, it is possible to acquire the date and time of the start of setup and the date and time of the end of machining.
Specifically, it is also possible to obtain the production results by the following procedure. That is, (1) the work instruction ID written in the QR code of the work instruction is written in the NFC tag attached to a clip, clear file, or the like via the QR reader and NFC writer. (2) Physically integrate the work instruction with the NFC tag by combining the work instruction with the clip or clear file. (3) Put work instructions and products together into the process. (4) At the start of the process work, when the work to list the work instruction in the process is performed, the IoT device reads the NFC tag tied to the work instruction. (5) Acquire the ID information of the read NFC tag and the process associated with the ID information of the IoT device. Note that the ID information of the IoT device and the registered process are linked in advance and stored. (6) By associating the work instruction ID with the process ID, the results such as the start of setup are acquired. (7) When the work of the process is completed, the work instructions are removed. (8) Triggered by the removal of the work instruction sheet, the IoT device notifies the server 1 that the NFC tag has been removed. (9) By transmitting to the server 1 that the NFC tag has been removed, a track record of completing processing of a certain process in the work order is obtained.
Since the production results can be acquired in real time by such a procedure, the person in charge of work W puts up the work instructions in the process before work as usual without being aware of the existence of the system, and removes it after completion to produce the product. It suffices to carry out the work of removing to the next process together with .
As a result, it is possible not only to reduce the number of man-hours for entering daily reports and to reduce entry errors, but also to omit the work of tabulating daily reports and inputting data into the system. In addition, it is possible to acquire and manage the progress of production performance against the production plan in real time, which has not been possible with conventional production management systems. As a result, improvement and quick customer service can be achieved.
Note that the reading unit 301 may read the date and time from the QR code (registered trademark) as described above, but it may also acquire the date and time using any sensing device such as reading by an RFID tag, surveillance camera, etc. . Also, using an IoT device, information such as date and time may be automatically acquired without any physical action by the worker W.

In addition, in the flowchart of the production plan creation process shown in FIG. 10, monthly and weekly production plans are created in steps S34 and S35. It is also possible to create a production plan such as

Also, for example, the series of processes described above can be executed by hardware or by software.
In other words, the functional configuration of FIG. 6 is merely an example and is not particularly limited.
That is, it is sufficient that the information processing system has a function capable of executing the above-described series of processes as a whole, and what kind of functional blocks are used to realize this function is not particularly limited to the example of FIG. Also, the locations of the functional blocks are not particularly limited to those shown in FIG. 6, and may be arbitrary.
Also, one functional block may be composed of hardware alone, software alone, or a combination thereof.

Further, for example, when a series of processes is executed by software, a program constituting the software is installed in a computer or the like from a network or a recording medium.
The computer may be a computer built into dedicated hardware.
Also, the computer may be a computer capable of executing various functions by installing various programs, such as a server, a general-purpose smart phone, or a personal computer.

Further, for example, a recording medium containing such a program is not only constituted by a removable medium (not shown) that is distributed separately from the device main body in order to provide the program to the user, but also is pre-installed in the device main body. It consists of a recording medium, etc. provided to the user in the

In this specification, the steps of writing a program recorded on a recording medium are not only processes that are performed chronologically in that order, but also processes that are not necessarily chronologically processed, and that are performed in parallel or individually. It also includes the processing to be executed.
For example, the order of "work plan for equipment personnel (work instructions)" and "issue of work instructions" in Fig. 3 may be reversed, or the order of "internal processing" and "outsourcing of processing" and vice versa. The order of steps S21 to S26 in FIG. 9 may be random, and the order of steps S31 and S32 in FIG. 10 may also be reversed.
Further, in this specification, the term "system" means an overall device composed of a plurality of devices, a plurality of means, or the like.

As described above, the information processing apparatus to which the present invention is applied can, for example, indicate the status of machines/equipment and personnel involved in all machining processes in a factory or the like, such as the start of setup, the end of setup, the start of machining, and the end of machining. It is possible to manage only four status transitions, and to manage the reflection of results on site to the machining plan based only on repetition of predetermined inputs (software buttons, etc.) at the timing of the above four statuses.
As a result, while minimizing the input work at the processing site, it is possible to grasp the situation in real time throughout the company with simple operations, and it is possible to automatically create daily reports.

Here, the information processing apparatus to which the present invention is applied may perform automatic performance input, for example.
That is, by arranging a work instruction printed at a processing site in a predetermined place by clipping it, (for example, by reading a QR code (registered trademark) printed on the work instruction) input information for starting setup is sent to an information processing device (for example, a server), and after the work is completed, the work instruction is removed from the clip and sent to the next step together with the processed product, so that the input information of the end of processing is transmitted to the server. .
As a result, the same effect as described above can be obtained while reducing the additional work at the machining site to zero.
The QR code (registered trademark) is merely an example, and can be replaced with any other sensing device such as an RFID (registered trademark) tag, reading by a surveillance camera, or the like.

Further, for example, the information processing apparatus to which the present invention is applied may execute process delay automatic notification on the shared dashboard.
In other words, the process management screen, which reflects the sequential status transitions, is shared by all sites, managers, clerks, etc., and when a delivery delay occurs, the color of the Gantt chart automatically changes, and everyone can see the situation on the same screen. can be shared.
As a result, there is no need to report the situation when a delay occurs, and it is possible to immediately talk about countermeasures among the processing site, manager, office worker, and the like.

Further, for example, the information processing apparatus to which the present invention is applied may execute processing that enables automatic coordination of large schedule>small schedule.
In other words, at the time of process planning, by registering the combination of necessary machines/equipment and persons in charge (persons who have skills and can be in charge) for all machining processes that will become parts, the administrator can manage the machining processes that will become parts. When a general schedule is entered by name, a screen may be displayed on which the machine/equipment necessary for the specific small schedule to be planned by the person in charge of the manufacturing site and the person in charge can be selected.
As a result, managers can set large schedules without worrying about resource allocation for small schedules, and shop floor managers can select only the machining processes that are subject to the small schedules that they themselves should set without omission. It is possible to concentrate on the setting of
