  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[System configuration]
FIG. 1 is a block diagram illustrating a configuration of an information processing system S including a server 1 according to an embodiment of the information processing apparatus of the present invention.
The information processing system S illustrated in FIG. 1 is configured to include at least a server 1, an administrator terminal 2, and a site terminal 3. The server 1, the administrator terminal 2, and the site terminal 3 are mutually connected via a network N such as the Internet (Internet).

The server 1 manages the operations of the administrator 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”) described later.
The administrator terminal 2 is an information processing device operated by an administrator M who manages production of a product, and includes, for example, a smartphone or a tablet.
The site terminal 3 is an information processing device operated by a worker W at the production site, and is composed of, for example, a smartphone or a tablet.
Note that the number of the manager terminal 2 and the site terminal 3 shown in FIG. 1 are both one, but this is merely an example, and both may be plural.
The specific contents of the functions of each of the server 1, the administrator terminal 2, and the site terminal 3 shown in FIG. 1 will be described later with reference to FIG.

  Next, an outline 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 outline of the small lot scheduler.

The small lot scheduler is a tool that assists a service that enables efficient management of progress by sharing a production plan of a small lot product among products between the manager M and the worker W. It is.
Here, the production plan refers to a plan relating to a production quantity and a production time of a product. The product referred to here is a broad concept including not only a final product provided to a consumer but also a product produced in a predetermined process and provided to the next process (for example, a component or the like when viewed from the final product).
That is, the production plan refers to a plan for determining which products and how much are to be produced 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 a "large-schedule production plan"), and the other is a work plan for one or more machines and equipment required for production (hereinafter, "one or more personnel"). Equipment staff work plan ”).

As shown in FIG. 2, the small lot scheduler prepares a quotation, prepares a production plan, prepares a work instruction, and arranges a material, which is performed on the manager M side, and arranges a material. Support the processing, inspection, and shipping of products.
Specifically, for example, when information on a production plan or information on a work instruction is input based on an operation of the manager M, the input contents are shared by the worker W via the server 1. Further, information on production results is input based on an operation of the worker W, 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 be applied to all products. By introducing the small lot scheduler into 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 work, for example. Can be enjoyed.

(Create quote)
The conventional manager M, when preparing an estimate, first designs all the processes required to produce the product based on the drawing of the product, and writes this as a process plan on paper. Output. The output process plan was sequentially circulated to the worker W in charge of each processing step, and the delivery date for each step was entered by the worker W in charge of each processing step. When the circulation of the process plan was completed, the manager M created an estimate while looking at the process plan in which the delivery date of each processing step was entered.
As described above, the conventional manager circulates the process plan output on paper when preparing the quotation by the conventional method, and estimates based on the information such as the delivery date entered in each processing step at the time of circulation. The trouble of writing 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, an estimate is automatically created. Here, the worker W in each processing step can operate the site terminal 3 and input the delivery date of the process in charge of himself, so that the work of outputting the process plan on paper and circulating it can be abolished. . Thereby, the time cost required for the input operation of the manager M can be reduced.

(Preparation of work instructions)
In addition, when issuing a work instruction to the worker W, the conventional manager M determines specific work contents in each processing step while looking at the contents of the estimate written by himself / herself. Work instructions were created by entering the details.
As described above, when issuing a work instruction by the conventional method, the manager M has to perform the work of creating the work instruction by re-entering the contents described in the created estimate.
On the other hand, when the small lot scheduler is introduced, the contents described in the estimate are automatically reflected in the work order, so that the manager M can avoid duplicate input work. . If it is not necessary to prepare an estimate, a work instruction is automatically generated based on information such as order information and product information. Thereby, the time cost required for the input operation of the manager M can be reduced.

(Create production plan)
Further, conventionally, when creating a production plan for each process, the manager M has determined a specific production plan for each processing step while looking at the contents of the work instruction sheet. Specifically, the names of the production parts and the number of the production parts for the machinery and equipment operated in each processing step, the number of staff to be arranged, and the like have been determined as a production plan. The production plan is transmitted to the worker W by being written on a white board or the like installed at the production site, and the worker W works according to the production plan written on the white board or the like.
As described above, when a production plan is created by a conventional method, a work plan is created by filling in a production plan created based on the contents of the created work order on a whiteboard or the like installed at a production site. The trouble of transmitting it to the person W.
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 are output to the site terminal 3 in real time. For this reason, the worker W can easily acquire the contents of the created production plan via the site terminal 3. Thereby, the time cost required for the input (entry) operation of the manager M can be reduced.

(Create production results)
In addition, the conventional manager M creates the production results while observing the duplicated work results described in the two documents, the daily report and the work instruction sheet, respectively created in each processing step.
As described above, when the work results are created by the conventional method, it has been troublesome that the duplicate work results are described in two documents, the daily report and the work instruction sheet, in each processing step. Further, since the manager M needs to collect and total the reports of 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 the small lot scheduler is introduced, the work input (entry) work in each processing step is simplified, so that the work results having contents duplicated in two documents, the daily report and the work instruction sheet, are provided. Is not required. Further, the relationship between the production result and the delivery date for each processing step can be managed in real time. Thereby, the time cost required for the input operation can be reduced.

As described above, according to the small lot scheduler, the side that manages the production results and the production site side can share the production results in real time while simplifying the operation of inputting the production results on the production site side.
That is, it is possible to eliminate the duplication of input work by the manager M and the worker W in each processing step. By introducing a small lot scheduler, for example, in terms of time cost, two hours It is also possible to reduce the above. Further, in terms of cost, assuming that the number of processes is five and the labor cost per hour is 3,600 yen, it is possible to reduce 7,800 yen per project.
Further, the production plan is so-called “visualized”, and is shared between the manager M and the worker W in real time. Thereby, the operation rate can be improved according to the operation state. Furthermore, early response to the delivery deadline is possible, so that the delivery delay can be prevented.

  Next, the flow of the small lot scheduler of 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 for a certain product X, an estimate and a plan for combining one or more processing steps (hereinafter referred to as “process plan”) based on predetermined estimation conditions indicated in the inquiry. Is created. When the contents of the created estimate and the process plan are approved by the customer, the production of the product X is ordered.
On the other hand, if an order is placed immediately without an inquiry, the production of the product X is received as it is.

If the product X for which production has been ordered is a repeat part number (reordered part number), the presence or absence of stock is checked, and if there is stock, inspection before shipment is performed. On the other hand, when there is no stock of the product X, a process plan having a production result is called, and a work order is created in order units based on the called process plan. The work instruction is created through the creation of a two-stage plan: a large-schedule production plan and a work schedule for equipment personnel.
If the product X is not a repeat part number (re-order part number) but a new part 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, the stock of materials required in each processing step is checked. When there is a stock of the material in each processing step, the work in each processing step is executed. On the other hand, when the stock of the material in each processing step is insufficient, the work in each processing step is executed after the order of the material and the acceptance of the delivered material are performed.

  In each processing step, registration of production results and registration of progress are performed. An inspection before shipment is performed on the produced product X. In addition, for processes requiring outsourcing, inspections before shipment are performed after order placement and delivery of outsourced products are received.

  When the pre-shipment inspection is performed on the product X, the contents of the inspection are recorded. Thereafter, when the product X is shipped, the contents of the shipment are recorded.

  Next, in the flowchart of FIG. 3, details of “in-house processing steps” and “production result registration” surrounded by broken lines will be described with reference to FIG. 4.

  FIG. 4 is a diagram showing details of “in-house processing steps” and “production result registration” surrounded by broken lines in the flowchart of FIG. Note that “in-house processing steps” and “registration of production results” surrounded by broken lines correspond to the processing executed in step S4 in FIG. 8 described below.

The production plan created for producing the product X is composed of a combination of one or more processing steps. FIG. 4A shows an example in which a combination of one or more processing steps constituting a production plan is a combination of an NC lathe step, a 5-axis machining center step, and a carburizing and quenching step.
Here, as shown in FIG. 4B, the small lot scheduler performs (1) start of setup, (2) end of setup, (3) start of processing, and (4) ) The production results can be managed by the transition between the four states of the end of processing.
That is, in the case of the example shown in FIG. 4A, the small lot scheduler performs (1) setup start, (2) setup for each of the NC lathe process, the 5-axis machining center process, and the carburizing and quenching process. The production results can be managed by four state transitions of end, (3) processing start, and (4) processing end.
The transition between these four states can be used as a common concept in any machining process. For this reason, the small lot scheduler is a versatile service that can be used in the processing of all products regardless of the field.

  In summary, by introducing the small lot scheduler, work instructions can be created in two stages: a large-schedule production plan and a facility staff work plan.

  In addition, as a supplement to FIG. 3, it is necessary that the product and the information are linked in manufacturing. The work instructions go through the processing steps together with the materials and work in process. Orders for outsourced products are issued based on work instructions, and are processed through the delivery of goods and delivery notes together. As for the movement of money, the order is matched with the work order → shipping list with the order list, and the ordered item is matched with the purchase order → delivery note. In the example of FIG. 3, the flow of bill payment is omitted.

The following effects can be obtained by introducing the small lot scheduler. In other words, in the process management in manufacturing, it is important how to obtain the production results with respect to the production plan in real time and use it for progress management and problem finding. Conventionally, real-time process control has been realized in some mass production models, but has not been standardized in small lot models. In this regard, by introducing the small lot scheduler, the confirmation of the production plan and the collection of the results can be input / reflected in one touch with a tablet or the like (the manager terminal 2 or the site terminal 3) in real time.
In addition, the administrator terminal 2 and the site terminal 3 do not need to be a tablet or the like in particular, and may be configured as an IoT device that does not require one-touch. In this case, the results can be automatically collected.

[Hardware configuration]

In the drive 20, a removable medium 30 made of a magnetic disk, an optical disk, a magneto-optical disk, a semiconductor memory, or the like is appropriately mounted. The program read from the removable medium 30 by the drive 20 is installed in the storage unit 18 as needed.
Further, the removable medium 30 can also store various data stored in the storage unit 18 in the same manner as the storage unit 18.

  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, when the administrator terminal 2 and the site terminal 3 are configured by a smartphone or a tablet, they have a touch panel as the output unit 16 and the input unit 17.

[Functional configuration]
FIG. 6 is a functional block diagram showing an example of a functional configuration for realizing the business support process and its sub-processes among the functional configurations of the server 1 in FIG.

  Here, the business support process is a series of processes for realizing the above-described small lot scheduler, and includes various sub-processes such as a basic information registration process, a production plan creation process, and a production result registration process. By executing the business support processing, problems such as redundant input and scattered information can be solved, so that information on production can be centrally managed in real time.

As shown in FIG. 6, in the CPU 11 of the server 1, when the basic information registration process is executed among the sub processes, the registration accepting unit 101 functions. Further, when the production plan creation process is executed, the plan creation unit 102 functions. When the production result registration process is executed, the result management unit 103, the result 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 result DB 403 are provided.

  The registration receiving unit 101 receives information (hereinafter, referred to as “user information”) required when 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. Thereby, the user information is registered in the small lot scheduler. Here, the user is not particularly limited. For example, the company C to which the manager M and the worker W belong in FIG. 1 is an example of a user. Further, what information is included in the user information is not particularly limited. For example, the user information may include a mail address, a login ID and a password, a company name as a contact, an address, a telephone number, a FAX number, a person in charge, a coupon code for using a small lot scheduler at a discount price, and the like. it can.

Further, the registration receiving unit 101 receives basic information of a user who uses the small lot scheduler. The received basic information is stored and managed in the registration information DB 401. Thus, the basic information is registered in the small lot scheduler. Hereinafter, such registration processing is referred to as “basic information registration processing”.
What information is included in the basic information of the user is not particularly limited. For example, it can include company information, factory information, department information, supplier information, process information, personnel information, and the like.

  Specifically, the company information includes information on operating hours and operating days for each company. By registering information on operating hours and operating days for each company, when a production plan is created automatically, the work (for example, setup work) by humans can be kept within the operating days and scheduled time for each company. be able to.

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

  The department information includes information on the department name, the affiliation, the operating hours and the operating days for each department. By enabling registration in units of departments, it is possible to create and confirm a production plan for each department.

  The supplier information includes information on the supplier name, management number, transaction relationship, outsourcing process, and the like. Information on the business partner can be registered together with the creation of the quote or the work instruction. Registered business partners can be automatically listed.

  The process information includes information on a factory to which the device belongs, a department to which the process belongs, a process category, a process control number, a process name, a unit price per hour, and a representative for each process as information on equipment and work. As long as the process division (for example, “cutting”) is between the same processes, the production plan may be allocated. The unit price per hour can be used in costing based on production plans and production results.

  The staff information includes information on the worker W, the factory to which the user belongs, the department to which the user belongs, the unit price per hour, the process in charge, the presence or absence of administrator authority, and the log-in history. Since production is performed on the premise of personnel, it is possible to prevent processes that are not linked to personnel from being reflected in the production plan. Since the information on personnel includes personal information, only the manager M may be allowed to browse, edit, and create a production plan. The unit price per hour can be used in costing based on production plans and production results.

The plan creating unit 102 creates a production plan including a combination of one or more processing steps for producing a product. Hereinafter, such a creation process is referred to as a “production plan creation process”.
Specifically, the plan creation unit 102 performs a production process including a combination of one or more processing steps based on order information, product information, and various types of information (user information and basic information) stored in the registration information DB 401. Create a plan. The created production plan is stored and managed in the production plan DB 402.
Here, the order information includes information such as a product name, a product number, a quantity, and a recipient of the ordered product. Further, the product information includes information such as a process classification, a setup time, a processing time, a worker W, a material, a number, and a delivery date.
Note that the production plan created by the plan creation unit 102 can be edited by performing an input operation on the manager terminal 2.

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

  When the order quantity of a product is managed by an order management section 107 described later, the plan creation section 102 creates a product production plan based on the order quantity managed by the order management section 107. be able to.

In addition, the plan creation unit 102 can execute control for presenting one or more combinations usable in a small schedule corresponding to a large schedule of a machining process. Specifically, the plan creation unit 102 registers in advance the necessary combination of the mechanical equipment and the worker W for all of one or more processing steps that are components of the production plan. After that, when a large-schedule production plan is created with the name of the machining process that is a component of the production plan, a screen on which one or more mechanical equipment and one or more personnel required for creating the facility personnel work plan can be selected. Is displayed on the site terminal 3.
Thereby, the manager M can create the large-schedule production plan without worrying about the resource allocation of the facility staff work plan. Further, the worker W (for example, the person in charge of the processing site) concentrates on the preparation of the facility personnel work plan by completely selecting only one or more processing steps to be planned by the facility personnel work plan. be able to.

  Information required when creating a production plan is not particularly limited. For example, information on orders includes classification of quotations or work orders, order management numbers, business partner names, factories and departments of delivery destinations, numbers for distinguishing products, names for distinguishing products, delivery requested by customers Information such as the number, the scheduled production start date, the final delivery date of the production plan, the delivery date for each process, and the production factory can be included. In addition, information on the product includes product number, product name, order of the process of producing the product, classification of each processing step, equipment name, name of person in charge for each process, setup time of each processing step (time for human work), Information such as the processing time of each processing step (time during which the machine operates), material and dimensions of the product, and the like can be included.

  The specific contents of the production plan are not particularly limited. For example, as shown in FIG. 7, a production plan may be created such that the contents of an order received, a product, one or more processes, materials, and one or more personnel are linked. A plurality of personnel (work staff W) may be arranged for each process. As a result, it is possible to appropriately switch between the workers W, so that a flexible and realistic production plan can be created. Further, the output format of the production plan is not particularly limited, and a production plan for each month, week, date and time, each process, each person in charge, or the like may be output.

The performance management unit 103 manages the production performance for each of the one or more processing steps by transitioning between four states of setup start, setup end, processing start, and processing end. Specifically, the performance management unit 103 receives input operations to the site terminal 3 in each of the four states at the start of setup of each processing step, at the end of setup, at the start of processing, and at the end of processing. Then, the performance management unit 103 acquires information on the date and time of each of these four states, triggered by the reception of the input operation. Information on the obtained date and time is stored and managed in the production result DB 403. As a result, information on the date and time of each of the four states is registered in the small lot scheduler. Hereinafter, such registration processing is referred to as “production result registration processing”.
Here, the specific mode of the input operation to the site terminal 3 is not particularly limited. However, in the present embodiment, as shown in FIG. You can get it.
Thus, the operation of inputting the production results on the production site side can be simplified.

The performance calculation unit 104 calculates the production performance for the production plan based on the respective dates and times of the four states of the start of setup, the end of setup, the start of machining, and the end of machining for each process. More specifically, the performance calculation unit 104 determines the time of each of the four states acquired by the performance management unit 103 at the start of setup, at the end of setup, at the start of machining, and at the end of machining. Then, the 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 obtained by a simple input operation to the site terminal 3, and the result calculation unit 104 calculates a detailed production result by checking the production number that is separately and continuously counted. can do.

The display control unit 105 executes control for displaying information related to a production plan and information related to a production result on the manager terminal 2 or the site terminal 3. Specifically, for example, the display control unit 105 stores the production plan created by the plan creation unit 102 and the production result calculated by the result calculation unit 104 in the manager terminal 2 and the site terminal 3 in the progress status. Control for identifying and displaying is performed accordingly. In addition, the specific method of performing the identification display according to the progress is not particularly limited. For example, the color of the Gantt chart automatically changes when a delay to the delivery date occurs, and this situation may be shared by the manager M and the worker W.
Thereby, the manager M and the worker W can confirm and share the production results with respect to the production plan in real time, so that the delay with respect to the delivery date can be detected early. As a result, it is possible to prevent delays in the delivery date, thereby improving the reliability of customers.

The stock management unit 106 manages the stock quantity of a product. Specifically, the stock management unit 106 manages the stock quantity of the product based on the production result stored in the production result DB 403 and the quantity of the actually shipped product.
Thus, the plan creation unit 102 can create a product production plan in consideration of the stock quantity managed by the stock management unit 106.

The order management unit 107 manages the order quantity of a product. Specifically, the order management unit 107 manages the order quantity stored in the production plan DB 402.
Thus, the plan creation unit 102 can create a product production plan in consideration of the order quantity managed by the order management unit 107.

  The reading unit 301 reads a predetermined identifier, and when the reading of the predetermined identifier being read becomes impossible, records the date and time when the reading became impossible. Specifically, for example, when the work instruction is placed at a position where it can be read, 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 when the setup started. Then, when it becomes impossible to read the QR code (registered trademark) of the work instruction sheet, the reading unit 301 acquires the date and time when the reading became impossible as the processing end date and time. That is, the worker W can acquire the date and time of the processing end simply by physically moving the work instruction document at the readable position to the unreadable position.

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 illustrating the flow of the business support process executed by the server 1 of FIG.

As shown in FIG. 8, the server 1 executes a series of processes as described below.
In step S1, the registration receiving unit 101 receives user information for using the small lot scheduler.
In step S2, the registration receiving unit 101 executes a basic information registration process which is a sub-process of the business support process. The detailed flow of the basic information registration process will be described later with reference to FIG.
In step S3, the plan creating unit 102 executes a production plan creating process that is a sub process of the business support process. The detailed flow of the production plan creation process will be described later with reference to FIG.
In step S4, the result management unit 103 executes a production result registration process. The detailed flow of the production result registration process will be described later with reference to FIG.
Thus, the business support processing ends.

  FIG. 9 is a flowchart illustrating the flow of the basic information registration process among the sub-processes constituting the business support process executed by the server 1 of FIG.

In each of steps S21 to S26, the registration receiving unit 101 receives the input of the user's company information, factory information, department information, supplier information, process information, and personnel information, respectively. Specifically, since the user is registered in company units, the administrator M as a contact of the user (company) inputs these pieces of information by operating the administrator terminal 2 and the registration receiving unit 101 Accept input contents.
In step S27, the registration receiving unit 101 determines whether all the essential information for registering the basic information has been received. Here, there is no particular limitation on what information the essential information is. For example, three pieces of information of the company information received in step S21, the process information received in step S25, and the personnel information received in step S26 may be the 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 returns to step S21. That is, the processing of steps S21 to S26 and the determination processing of step S27 are repeatedly executed until it is determined to be YES in step S27.
In step S28, the registration receiving unit 101 registers the various information received in steps S21 to S26 as basic information.
Thus, the basic information registration process ends, and the process returns to the flowchart of FIG.

  FIG. 10 is a flowchart illustrating 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 plan creation unit 102 receives product information.
In step S33, the plan creating unit 102 determines whether all the order information and the product information have been received.
If all the order information and the 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 returns to step S31. That is, the processing of steps S31 and S32 and the determination processing of step S33 are repeatedly executed until it is determined to be YES 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.
Thus, the production plan creation processing ends, and the processing returns to the flowchart of FIG.

  FIG. 11 is a flowchart illustrating the flow of the production result 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 receives a selection of a production plan. Specifically, the performance management unit 103 receives an operation of selecting one production plan from one or more production plans displayed on the manager terminal 2 or the site terminal 3.
In step S <b> 42, the display control unit 105 executes control to display the received process information of the one production plan on the manager terminal 2 or the site terminal 3.
In step S43, the performance management unit 103 receives an input operation to the site terminal 3 in four states, ie, at the start of the setup of the machining process, at the end of the setup, at the start of the machining, and at the end of the machining. Then, the performance management unit 103 acquires information on the date and time of these four states, triggered by the reception of the input operation.
In step S44, the performance calculation unit 104 determines the process status of each process based on the obtained date and time of the four states of the setup start, setup end, machining start, and finish of each process. Calculate the actual production against the production plan.
In step S45, the display control unit 105 executes control to display the calculated production results on the manager terminal 2 or the site terminal 3.
In step S46, the performance calculation unit 104 accepts editing of the production performance displayed on the manager terminal 2 or the site terminal 3 as necessary. The display control unit 105 executes control for displaying the edited production results on the manager terminal 2 or the site 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 result management unit 103 stores the calculated production result or the production result edited as necessary in the production result DB 403 and manages the result.
Thus, the production result registration process ends, and the process returns to the flowchart of FIG.

Next, a specific example of an input operation to the site terminal 3 in the production result registration process shown in FIG. 11 will be described with reference to FIG.
FIG. 12 is a diagram illustrating a specific example of an operation of inputting a production result to the site terminal 3.

  FIG. 12A shows an example of a screen displayed on the site terminal 3 at the start of setup in one processing step. As shown in FIG. 12A, detailed information of the process is displayed on the site terminal 3, and a setup work start button B1 is displayed on the display area F1. The worker W presses the setup work start button B1 at the timing to start the setup work. The result management unit 103 receives an operation of pressing the setup work start button B1. Then, the performance management unit 103 acquires information on the date and time at that time, triggered by the reception of the pressing operation. Information on the obtained date and time is stored and managed in the production result DB 403. As a result, information on the date and time of the start of the setup operation is registered in the small lot scheduler.

  FIG. 12B shows an example of a screen displayed on the site terminal 3 at the end of the setup in one processing step. As shown in FIG. 12B, the site terminal 3 displays the detailed information of the process, and the display area F1 displays a setup work end button B2. The worker W presses the setup work end button B2 at the timing when the setup work has been completed. The result management unit 103 receives an operation of pressing the setup work end button B2. Then, the performance management unit 103 acquires information on the date and time at that time, triggered by the reception of the pressing operation. Information on the obtained date and time is stored and managed in the production result DB 403. Thereby, information on the date and time of the setup work end is registered in the small lot scheduler.

  As described above, when the predetermined button is pressed at each timing of the setup start and the setup end in one machining process, each date and time can be acquired. The date and time of the processing start and the processing end are obtained in the same manner. That is, the worker W presses a processing start button (not shown) at the start of the processing, and presses a processing end button (not shown) at the end of the processing.

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

  The manager terminal 2 and the site terminal 3 can display detailed information of the production result registered in the production result registration process in real time. Specifically, as shown in FIG. 13, the setup time (minute), the total processing time (minute), the material unit price (yen), the number, the number of defects, the previous process completion date and time, the setup start date and time, the setup end Date and time, setup stop time, processing start date and time, processing end date and time, processing stop time, and planned and actual values for the next process start date and time, and items to be sent can be displayed on the manager terminal 2 and the site terminal 3.

  The production results displayed on the manager terminal 2 and the site terminal 3 are corrected and re-registered by pressing the "result re-registration" button B3 and the "restore" button B4 displayed in the display area F2. You can also. Accordingly, even when the setup work start button B1, the setup work end button B2, or the like is forgotten to be pressed or is erroneously pressed, it can be appropriately corrected.

  FIG. 14 is a diagram illustrating a specific example of the progress of the production results displayed on the manager terminal 2 and the site terminal 3.

  The progress status of the production result registered by the production result registration process can be displayed on the manager terminal 2 and the site terminal 3 in real time. More specifically, as shown in FIG. 14A, a production schedule for each case, which is distinguished by order number, product number, and product name, can be displayed in real time.

  As in the example shown in FIG. 14A, the completed process is indicated by a solid band, and the unexecuted process is indicated by a shaded band, and is identified and displayed according to the progress of the process. it can. Further, for example, a process indicated by a moving diagonal line indicates a process in progress, a process indicated by a stopped diagonal line is temporarily suspended, and a process with a blinking red edge indicates a process delay, etc. Bands can be identified and displayed. Accordingly, the manager M and the worker W can grasp the progress at a glance, and can prevent a delivery delay.

  Further, detailed information of production results for each case can be displayed on the manager terminal 2 and the site terminal 3 in real time. Specifically, as in the example shown in FIG. 14B, detailed information on the actual production results can be displayed in work instruction document units (ie, order units). Detailed information on production results includes, for example, order number, order receiver, destination, product number, surface, setup time for each process, processing time, person in charge, material (material dimensions), material unit price, subcontract unit price, number of conforming products, Information such as the number of defective products, cost, delivery date, total time required for processing, single item cost, estimated cost, and the like 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, and the like within a range that can achieve the object of the present invention are included in the present invention. is there.

  For example, in the above-described embodiment, it is described that the technology is directed to the production of small lot products, but this is a technology that is particularly effective when managing the production of small lot products. It is nothing special. Therefore, the products are not limited to small lot products, but may be middle lot or large lot products.

In the above-described embodiment, the result management unit 103 receives the input operation to the site terminal 3 in each of the above-described four states, and uses this as a trigger to acquire information on the date and time of each of these four states. However, the production results can be obtained by using other methods. For example, the date and time of the setup start and the date and time of the processing end can be acquired based on the state of the reading of the predetermined identifier by the reading unit 301.
Specifically, the production results can be obtained by the following procedure. That is, (1) the work instruction ID written in the QR code (registered trademark) of the work instruction is written to the NFC tag pasted on a clip, a clear file, or the like via the QR reader and the NFC writer. (2) By setting a work instruction sheet and a clip or a clear file as a set, the NFC tag of the work instruction sheet is physically integrated. (3) The work instruction and the product are put into the process together. (4) When the work in which the work instruction is listed in the process is performed at the start of the process work, the IoT device reads the NFC tag associated with 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. The ID information of the IoT device and the registered process are stored in association with each other in advance. (6) By linking the work instruction ID and the process ID, results such as start of setup are acquired. (7) When the work of the process is completed, the listed work instruction is removed. (8) With the removal of the work instruction as a trigger, the IoT device transmits to the server 1 that the NFC tag has been removed. (9) By transmitting the fact that the NFC tag has been removed to the server 1, the result of the completion of the processing of a certain step in the work instruction is acquired.
Since the production results can be obtained in real time by such a procedure, the worker W puts up the work instruction in the process as usual before the work without being aware of the existence of the system, and removes the product after completion and removes the product. And the work to be removed to the next step.
As a result, it is possible not only to reduce the man-hours and entry mistakes in the daily report entry, but also to omit the work of tabulating the daily report and inputting it to the system. Further, it is possible to obtain and manage in real time the progress of production results with respect to a production plan, which cannot be realized by a conventional production management system. As a result, improvement and quick customer response can be realized.
Note that the reading unit 301 may read the date and time from the QR code (registered trademark) as described above, but may obtain the date and time using any sensing device such as an RFID tag or a monitoring camera. . In addition, information such as the date and time may be automatically acquired using the IoT device without the worker W taking any physical action.

  Further, in the flowchart of the production plan creating process shown in FIG. 10, it is assumed that monthly and weekly production plans are created in steps S34 and S35, but the present invention is not limited to this. Etc. can be created.

Further, for example, the above-described series of processing can be executed by hardware or can be executed by software.
In other words, the functional configuration in 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 processing as a whole, and what kind of functional block is used to realize this function is not particularly limited to the example of FIG. Further, the location of the functional block is not particularly limited to FIG. 6 and may be arbitrary.
In addition, one functional block may be constituted by hardware alone, software alone, or a combination thereof.

Further, for example, when a series of processing 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 embedded in dedicated hardware.
Further, the computer may be a computer that can execute various functions by installing various programs, for example, a general-purpose smartphone or a personal computer other than a server.

  Further, for example, a recording medium including such a program is not only constituted by a removable medium (not shown) distributed separately from the apparatus main body in order to provide the user with the program, but also a state in which the recording medium is pre-installed in the apparatus main body. And a recording medium provided to the user.

In the present specification, steps for describing a program recorded on a recording medium are not limited to processing performed in chronological order according to the order, but are not necessarily performed in chronological order, but are performed in parallel or individually. This includes the processing to be executed.
For example, in FIG. 3, the order of “equipment personnel work plan (work instruction)” and “work instruction issuance” may be reversed, or the order of “in-house processing” and “outsourcing of processing” may be reversed. And vice versa. Further, the order of the processes in steps S21 to S26 in FIG. 9 may be in any order, and the order of steps S31 and S32 in FIG. 10 may be reversed.
Also, in this specification, the term system refers to an entire device including a plurality of devices and a plurality of means.

As described above, the information processing apparatus to which the present invention is applied, for example, displays the status of machines / equipment and persons in charge of all processing steps, such as a factory, at the start of setup, at the end of setup, at the start of processing, and at the end of processing. Only the four status transitions can be managed, and the reflection of the actual results on the processing plan at the site can be managed based on only the repetition of a predetermined input (such as a software button) at the timing of the four statuses.
As a result, while minimizing input operations at the processing site, real-time status can be grasped company-wide with only simple operations, and daily reports can be created automatically.

Here, the information processing apparatus to which the present invention is applied may execute, for example, automatic result input.
That is, by arranging the work instruction printed at the processing site between the clips at a predetermined position, the input information of the start of setup (for example, by reading the QR code (registered trademark) printed on the work instruction) May be transmitted to an information processing apparatus (for example, a server), and after the work is completed, the work instruction may be removed from the clip and sent to the next process together with the processed product, so that the input information of the processing completion may be transmitted to the server. .
As a result, the same effect as described above can be obtained with zero additional work at the processing site.
It should be noted that the QR code (registered trademark) is merely an example, and any other sensing device such as an RFID (registered trademark) tag and reading by a surveillance camera can be used.

Further, for example, the information processing apparatus to which the present invention is applied may execute a process delay automatic notification in the shared dashboard.
In other words, the process management screen that reflects the sequential status transition is shared by all sites, managers, clerks, etc. If a delivery deadline occurs, the color of the Gantt chart automatically changes, and all the people are on the same screen. May be shared.
This eliminates the need for a situation report at the time of the occurrence of a delay, and allows the processing site, manager, clerk, and the like to immediately talk about measures.

Further, for example, the information processing apparatus to which the present invention is applied may execute a process that enables automatic coordination of large schedule> small schedule.
That is, at the time of process planning, a combination of necessary machines / equipment and a person in charge (a person who has skills and can be in charge) is registered for all the machining processes to be parts, so that the administrator can process the parts in the machining process. When a large schedule is input by name, a screen on which a machine / equipment and a person in charge necessary for a specific small schedule to be planned by a processing site manager may be displayed.
This allows the administrator to set a large schedule without worrying about resource allocation for small schedules, and the site manager can select only the machining processes for which the small schedule should be set by himself without fail. It is possible to concentrate on the setting.

  In addition, for example, the information processing apparatus to which the present invention is applied can reflect the results in the inventory management system and can cooperate with the order management system.

In other words, the information processing apparatus to which the present invention is applied can adopt various embodiments having the following configurations.
