[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the figures, as embodiments for carrying out the present invention.

[0010] Figure 1 shows a circuit board mounting system 10. The system 10 shown in Figure 1 is a system for mounting electronic components onto a circuit board. The circuit board mounting system 10 consists of four electronic component mounting devices (hereinafter sometimes abbreviated as "mounting devices") 12. The four mounting devices 12 are arranged in a row adjacent to each other. In the following description, the direction in which the mounting devices 12 are arranged will be referred to as the X-axis direction, and the horizontal direction perpendicular to that direction will be referred to as the Y-axis direction.

[0011] The four mounting devices 12 have substantially the same configuration as each other. Therefore, one of the four mounting devices 12 will be described as a representative. As shown in FIG. 2, the mounting device 12 has one system base 14 and two mounting machines 16 adjacent to each other on the system base 14. Each mounting machine 16 mainly includes a mounting machine body 20, a transfer device 22, a mounting head moving device (hereinafter sometimes abbreviated as "moving device") 24, a mounting head 26, and a supply device 28.

[0012] The mounting machine body 20 is composed of a frame 30 and a beam 32 mounted on the frame 30.

[0013] The transfer device 22 includes two conveyor devices 40 and 42. The two conveyor devices 40 and 42 are arranged on the frame 30 so as to be parallel to each other and extend in the X-axis direction. Each of the two conveyor devices 40 and 42 transports a circuit board supported by each conveyor device 40 and 42 in the X-axis direction by an electromagnetic motor (see FIG. 3) 44. The circuit board transported by each conveyor device 40 and 42 is held by a board holding device (see FIG. 3) 46 at a predetermined position.

[0014] The moving device 24 is an XY robot type moving device. The moving device 24 includes an electromagnetic motor (see FIG. 3) 52 that slides the slider 50 in the X-axis direction and an electromagnetic motor (see FIG. 3) 54 that slides the slider 50 in the Y-axis direction. The mounting head 26 is attached to the slider 50, and the mounting head 26 moves to an arbitrary position on the frame 30 by the operation of the two electromagnetic motors 52 and 54.

[0015] The mounting head 26 is used to mount electronic components onto a circuit board. The mounting head 26 has a suction nozzle 60 provided on its lower end surface. The suction nozzle 60 is connected to a positive / negative pressure supply device (see Figure 3) 66 via negative pressure air and positive pressure air passages. The suction nozzle 60 attracts and holds electronic components using negative pressure and releases the held electronic components using positive pressure. The mounting head 26 also has a nozzle lifting device (see Figure 3) 68 that raises and lowers the suction nozzle 60. The nozzle lifting device 68 allows the mounting head 26 to change the vertical position of the held electronic component. The suction nozzle 60 is detachable from the mounting head 26 and can be replaced according to the size of the electronic component.

[0016] The supply device 28 is a feeder-type supply device and is located at the end of the frame 30. The supply device 28 has multiple tape feeders 70. The tape feeders 70 house the tape components wound around them. The tape components are electronic components taped onto a carrier tape. The tape feeders 70 then feed out the tape components using a delivery device (see Figure 3) 76. In this way, the feeder-type supply device 28 supplies electronic components at the supply location by feeding out the tape components. The tape feeders 70 are detachable from the frame 30, allowing for replacement of electronic components, etc.

[0017] In addition, as shown in FIG. 3, the substrate processing system 10 includes a control device 80. The control device 80 includes a controller 82 and a plurality of drive circuits 86. The plurality of drive circuits 86 are connected to the electromagnetic motors 44, 52, 54, the substrate holding device 46, the positive / negative pressure supply device 66, the nozzle lifting device 68, and the feeding device 76. The controller 82 includes a CPU, a ROM, a RAM, etc., and is mainly a computer, and is connected to the plurality of drive circuits 86. Thereby, the operations of the transfer device 22, the moving device 24, etc. are controlled by the controller 82. Note that a production program 88 is stored in the controller 82, and the controller 82 produces a circuit board by controlling the operations of the transfer device 22, the moving device 24, etc. according to the production program 88.

[0018] Specifically, first, a circuit board is carried into the mounter 16 arranged at the most upstream among the eight mounters 16 constituting the substrate processing system 10. Then, in that mounter 16, the controller 82 outputs a command according to the production program 88, whereby the circuit board is transported to the working position and held at that position by the substrate holding device 46. Also, the tape feeder 70 feeds out the taped components and supplies the electronic components at the supply position according to the command of the controller 82 according to the production program 88. Then, the mounting head 26 moves above the supply position of the electronic components according to the command of the controller 82 according to the production program 88, and sucks and holds the electronic components by the suction nozzle 60. Subsequently, the mounting head 26 moves above the circuit board and mounts the held electronic components on the circuit board. When the operation of mounting the electronic components on the circuit board is completed, the circuit board is transported downstream and carried into the mounter 16 arranged on the downstream side. Then, by sequentially executing the above mounting operation in each mounter 16, a circuit board with electronic components mounted thereon is produced.

[0019] In this way, the controller 82 produces circuit boards by controlling the operation of the transport device 22, the moving device 24, etc., according to the production program 88. The controller 82 then stores production information for the produced circuit boards. The production information for the circuit boards includes the type of circuit board, the date and time of production, the number of circuit boards produced, the type of production program used for producing the circuit boards, and the status information of the circuit board work system 10 at the time of circuit board production. The status information of the circuit board work system 10 includes the planned production time, the actual production time, the dwell time of the circuit boards, and the setup changeover time. Incidentally, the planned production time is the planned production time for the circuit boards and is entered by the operator. The actual production time is the time during which the transport device 22, the moving device 24, the mounting head 26, etc. are actually operating in the circuit board work system 10 at the time of circuit board production and is measured at the time of circuit board production. In other words, the production time is the time when the circuit board work system 10 is stopped due to errors, parts replenishment, setup changes, etc., from the planned production time. Furthermore, the dwell time of a circuit board is the time it remains in the upstream mounting machine when the circuit board is being transported from the upstream mounting machine to the downstream mounting machine in the board handling system, while mounting work on another circuit board is being performed in the downstream mounting machine. The dwell time of the circuit board is also measured during the production of the circuit board. Additionally, the changeover time is the time required for a changeover that is performed when the type of circuit board being produced is changed, and the changeover time is also measured during the production of the circuit board.

[0020] Thus, the controller 82 stores production information of the manufactured circuit boards, and the manufacturer of the circuit board work system 10 uses this production information to evaluate the production line of the circuit board work system 10. Specifically, the worker, that is, the customer of the circuit board work system 10, sends production information for a predetermined period, for example, one week, to the manufacturer of the circuit board work system 10. The manufacturer of the circuit board work system 10 then evaluates the production line of the circuit board work system 10 based on the production information.

[0021] As part of the evaluation of the production line, the operating rate of the PCB work system 10 is assessed. The operating rate of the PCB work system 10 is the ratio of actual production time to planned production time, and is expressed as a percentage. Therefore, the operating rate of the PCB work system 10 is calculated based on the planned production time and actual production time included in the status information of the production information. The operating rate of the PCB work system 10 is calculated on a daily basis. The calculated operating rate is then evaluated, and the closer the operating rate is to 100%, that is, the higher the ratio, the higher the evaluation.

[0022] Furthermore, as part of the evaluation of the production line, the dwell time of circuit boards in the circuit board handling system 10 is evaluated. The dwell time of circuit boards is the ratio of the dwell time of circuit boards to the planned production time and is expressed as a percentage. Therefore, the dwell time of circuit boards is calculated based on the planned production time and the dwell time of circuit boards included in the status information of the production information. The dwell time of circuit boards is also calculated based on the operating rate on a daily basis. The calculated dwell time is then evaluated, with a dwell time closer to 0%, that is, a lower ratio, being evaluated more highly.

[0023] Furthermore, the setup time in the circuit board handling system 10 is evaluated as part of the production line evaluation. The status information in the production information includes setup time, and the total setup time on a daily basis is calculated. The calculated setup time is then evaluated, with shorter setup times receiving higher evaluations.

[0024] Thus, the operating rate of the circuit board handling system 10, the dwell rate of circuit boards, and the changeover are evaluated. However, the operating rate of the circuit board handling system 10, the dwell rate of circuit boards, and the changeover differ greatly depending on the production operation when the circuit boards are produced. Specifically, the production operation is a production method in a circuit board handling system that produces circuit boards, indicated by the number of types of circuit boards produced over a predetermined period, for example, per day, and the number of circuit boards of each type produced, and is a production method that indicates the production volume of circuit boards. For example, when the number of types of circuit boards produced over a predetermined period is small and the number of circuit boards of each type produced is large, the circuit board production operation is small-variety, high-volume production (hereinafter referred to as "high-volume production"). In high-volume production, the number of types of circuit boards produced per day over a predetermined period is 1 to 2. Also, when the number of types of circuit boards produced over a predetermined period is large and the number of circuit boards of each type produced is small, the circuit board production operation is large-variety, low-volume production (hereinafter referred to as "low-volume production"). In low-volume production, the number of types of circuit boards produced per day over a predetermined period is 11 or more. Furthermore, production operations between mass production and small-scale production are classified as medium-scale production. In medium-scale production, the number of circuit board types produced per day is typically between 3 and 10.

[0025] In a circuit board assembly system, when circuit boards are produced in mass production, the number of setup changes is small because the work is performed on a limited number of circuit board types. On the other hand, when circuit boards are produced in small quantities, the number of setup changes is large because the work is performed on a wide variety of circuit board types. Thus, in small quantities, the number of setup changes is higher compared to mass production, resulting in longer setup times and shorter actual production times. In other words, the utilization rate in small quantities is lower than in mass production. Therefore, it is not possible to properly evaluate the utilization rate by using the same criteria for both small quantities and mass production. Thus, it is necessary to set the criteria for evaluating the utilization rate, that is, the evaluation threshold, higher for mass production and lower for small quantities.

[0026] Furthermore, in a board mounting system, when boards are produced in mass production, mounting work is performed on a small number of circuit board types, making it easier to equalize the working time of the multiple mounting machines that make up the board mounting system. On the other hand, when boards are produced in small quantities, mounting work is performed on many different types of circuit boards, making it difficult to equalize the working time of the multiple mounting machines that make up the board mounting system. This is because, in order to improve production efficiency, it is desirable to minimize the time required for setup changes, such as changing the tape feeder that supplies components to be mounted on the board or changing its supply position. Therefore, by standardizing the arrangement of tape feeders when producing each type of board, setup time can be shortened. Due to these constraints of standardization, it becomes difficult to equalize the working time of multiple mounting machines, and this becomes more difficult as the number of board types to be standardized increases. Thus, in small-volume production, compared to mass production, it is difficult to equalize the working time of the multiple mounting machines that make up the board mounting system, resulting in variations in the working time of each of the multiple mounting machines, which leads to longer dwell times for circuit boards. In other words, the retention rate of circuit boards in small-scale production is higher than that of circuit boards in mass production. Therefore, if the retention rate of circuit boards in small-scale production and mass production are evaluated using the same criteria, it will not be possible to properly evaluate the retention rate of circuit boards. Thus, it is necessary to set the criteria for evaluating the retention rate of circuit boards, that is, the evaluation threshold, higher for small-scale production and lower for mass production.

[0027] Furthermore, production operation refers to a production method in a board-to-board work system that produces circuit boards, indicating whether to produce circuit boards for a predetermined period, for example, one day, without changing the tape feeder, or to produce circuit boards with the tape feeder changed, and indicating whether or not the tape feeder is changed. In other words, for example, if a board-to-board work system produces several types of circuit boards in one day, then if the components to be mounted on those several types of circuit boards are those components, then multiple tape feeders supplying those components can be mounted together on the mounting machine. In such cases, the board-to-board work system can produce circuit boards in one day without changing the tape feeder. The production method of producing circuit boards in one day without changing the tape feeder is referred to as the no-change production method. Also, for example, if a board-to-board work system produces 10 or more types of circuit boards in one day, the number of components to be mounted on those 10 or more types of circuit boards is very large, so it is not possible to mount multiple tape feeders supplying those components together on the mounting machine. In such cases, it is not possible to produce circuit boards in a circuit board handling system for a full day without changing the tape feeder. Therefore, when the type of circuit board being produced changes, the tape feeder is changed to produce the board. This production method, which involves changing the tape feeder to produce the board, is referred to as the exchange production method.

[0028] Furthermore, in a PCB production system where PCBs are produced using a no-exchange production method, the setup time is shortened because the tape feeder is not replaced during setup changes. However, during setup changes, there are generally tasks other than tape feeder replacement, such as setting up the production program and various tasks associated with changing the type of PCB being produced, so setup time will still be somewhat long even without tape feeder replacement. Also, in a PCB production system where PCBs are produced using an exchange production method, the tape feeder is replaced during setup changes, so the setup time in the exchange production method is naturally longer than in the no-exchange production method. For this reason, it is not possible to properly evaluate setup time by using the same criteria for both the exchange production method and the no-exchange production method. Therefore, it is necessary to set the criteria for evaluating setup time, that is, the evaluation threshold, lower for the no-exchange production method and higher for the exchange production method.

[0029] Thus, the operating rate of the board handling system 10, the dwell time of the circuit boards, and the changeover time vary greatly depending on the production operation when the circuit boards are produced. Therefore, manufacturers need to recognize the production operation of the boards and set evaluation thresholds according to that production operation. In this case, manufacturers have been contacting customers to inquire about their production operations or visiting customers to gather information on their production operations, but this process of confirming production operations takes time, resulting in delays in obtaining evaluation results.

[0030] Therefore, the manufacturer uses the information processing device 100 shown in Figure 4 to estimate the production operation of the substrate based on the data contained in the production information, and evaluates the production line of the substrate work system according to an evaluation threshold corresponding to the estimated production operation. The information processing device 100 includes a production operation estimation unit 102, an operating rate evaluation unit 104, a dwell rate evaluation unit 106, a setup change evaluation unit 108, and an evaluation result output unit 110.

[0031] The production operation estimation unit 102 is a functional unit for estimating the production operation of circuit boards based on the data included in the production information. As mentioned above, the production information includes the production date and time of the circuit board and the production program used to produce the circuit board. Therefore, the production operation estimation unit 102 calculates the number of times the production program to be evaluated is changed in a day based on the production date and time of the circuit board and the production program used to produce the circuit board included in the production information.

[0032] Furthermore, if the production operation of the circuit board is mass production, the number of types of circuit boards produced per day is 1 to 2, and the number of setup changes is 0 to 1. If the production operation of the circuit board is medium production, the number of types of circuit boards produced per day is 3 to 10, and the number of setup changes is 2 to 9. If the production operation of the circuit board is small production, the number of types of circuit boards produced per day is 11 or more, and the number of setup changes is 10 or more. Therefore, if the number of setup changes per day is known, the production operation can be estimated. When a setup change is performed, the production program is changed. Therefore, the number of times the production program is changed per day is the same as the number of setup changes per day. Accordingly, the production operation estimation unit 102 estimates the production operation of the circuit board to be evaluated for one day based on the number of times the production program is changed, which is calculated based on the production information.

[0033] In other words, the production operation estimation unit 102 estimates that if the number of production program changes is 1 or less, the number of setup changes will also be 1 or less, and therefore the production operation is mass production. Furthermore, if the number of production program changes is 2 to 9, the production operation estimation unit 102 estimates that the production operation is medium-volume production, and therefore the number of setup changes will also be 2 to 9. Furthermore, if the number of production program changes is 10 or more, the production operation estimation unit 102 estimates that the production operation is small-volume production, and therefore the number of setup changes will also be 10 or more.

[0034] Furthermore, the production program included in the production information stores information such as the type of supply component, mounting position, and identification number of the tape feeder installed on the mounting machine during the circuit board mounting operation, in order to appropriately supply components to the circuit board being manufactured. Therefore, by analyzing the production program executed on the day being evaluated, it is possible to determine whether or not the tape feeder was replaced on that day. Accordingly, the production operation estimation unit 102 analyzes the production program executed on the day being evaluated and determines whether or not there has been a change in the mounting position and identification number of the tape feeder installed on each of the mounting machines in the circuit board work system. If there is no change in the mounting position and identification number of the tape feeder, the production operation estimation unit 102 estimates that the circuit board was produced on the day being evaluated using the no-replacement production method. On the other hand, if there is a change in the mounting position and identification number of the tape feeder, the production operation estimation unit 102 estimates that the circuit board was produced on the day being evaluated using the replacement production method.

[0035] Furthermore, the operating rate evaluation unit 104 is a functional unit that identifies an evaluation threshold for the operating rate according to the production operation estimated by the production operation estimation unit 102, and evaluates the operating rate based on the identified evaluation threshold. In other words, the operating rate evaluation unit 104 changes the evaluation threshold for the operating rate based on the production operation estimated by the production operation estimation unit 102 and evaluates the operating rate. Specifically, the information processing device 100 stores map data as shown in Figure 5. In this map data, an evaluation threshold for the operating rate is set for each score from 0 to 20, and the higher the score, the higher the evaluation threshold for the operating rate. In addition, the map data is divided into three production operations: an evaluation threshold for the operating rate during mass production, an evaluation threshold for the operating rate during medium-volume production, and an evaluation threshold for the operating rate during small-volume production. The operating rate evaluation unit 104 then uses this map data to identify an evaluation threshold for the operating rate according to the production operation estimated by the production operation estimation unit 102, and evaluates the operating rate with a score corresponding to the identified evaluation threshold.

[0036] Specifically, the utilization rate evaluation unit 104 identifies an evaluation threshold for the utilization rate corresponding to the production operation estimated by the production operation estimation unit 102. In this case, for example, if the production operation estimation unit 102 estimates medium-volume production as the production operation, the utilization rate evaluation unit 104 identifies an evaluation threshold for the utilization rate corresponding to medium-volume production. Furthermore, as described above, the utilization rate evaluation unit 104 calculates the utilization rate for the day to be evaluated based on the planned production time and actual production time included in the status information of the production information. The utilization rate evaluation unit 104 then identifies the maximum score at which the calculated utilization rate is equal to or greater than the evaluation threshold corresponding to the estimated production operation. In other words, if the estimated production operation is medium-volume production and the calculated utilization rate is 71%, the utilization rate evaluation unit 104 evaluates the maximum score (17 points) at which a utilization rate of 71% is equal to or greater than the evaluation threshold corresponding to medium-volume production as the utilization rate evaluation score.

[0037] Furthermore, the retention rate evaluation unit 106 is a functional unit that identifies an evaluation threshold for the retention rate of circuit boards according to the production operation estimated by the production operation estimation unit 102, and evaluates the retention rate of circuit boards based on the identified evaluation threshold. In other words, the retention rate evaluation unit 106 changes the evaluation threshold for the retention rate based on the production operation estimated by the production operation estimation unit 102 and evaluates the retention rate. Specifically, the information processing device 100 stores map data as shown in Figure 6. In this map data, an evaluation threshold for the retention rate is set for every 0 to 20 points, and the higher the points, the lower the evaluation threshold for the retention rate. In addition, the map data is divided into two production operations: an evaluation threshold for the retention rate during mass production and an evaluation threshold for the retention rate during medium-volume and small-volume production. The retention rate evaluation unit 106 then uses this map data to identify an evaluation threshold for the retention rate corresponding to the production operation estimated by the production operation estimation unit 102, and evaluates the retention rate with points corresponding to the identified evaluation threshold.

[0038] Specifically, the retention rate evaluation unit 106 identifies an evaluation threshold for the retention rate corresponding to the production operation estimated by the production operation estimation unit 102. In this case, for example, if the production operation estimation unit 102 estimates medium-volume production as the production operation, the retention rate evaluation unit 106 identifies an evaluation threshold for the retention rate corresponding to medium-volume production. Furthermore, as described above, the retention rate evaluation unit 106 calculates the retention rate for the day to be evaluated based on the planned production time and retention time included in the status information of the production information. Then, the retention rate evaluation unit 106 identifies the maximum score at which the calculated retention rate is less than or equal to the evaluation threshold corresponding to the estimated production operation. In other words, if the estimated production operation is medium-volume production and the calculated retention rate is 22%, the retention rate evaluation unit 106 evaluates the maximum score (16 points) at which the retention rate of 22% is less than or equal to the evaluation threshold corresponding to medium-volume production as the evaluation score for the retention rate.

[0039] Furthermore, the setup change evaluation unit 108 is a functional unit that identifies an evaluation threshold for setup change time according to the production operation estimated by the production operation estimation unit 102, and evaluates the setup change based on the identified evaluation threshold. In other words, the setup change evaluation unit 108 evaluates the setup change by changing the evaluation threshold for setup change time based on the production operation estimated by the production operation estimation unit 102. Specifically, the information processing device 100 stores map data as shown in Figure 7. In this map data, an evaluation threshold for setup change time is set for every 0 to 20 points, and the higher the points, the lower the evaluation threshold for setup change time. In addition, the map data is divided into two production operations: an evaluation threshold for setup change time in a no-exchange production method and an evaluation threshold for setup change time in an exchange production method. The setup change evaluation unit 108 then uses this map data to identify an evaluation threshold for setup change time according to the production operation estimated by the production operation estimation unit 102, and evaluates the setup change with a score corresponding to the identified evaluation threshold.

[0040] Specifically, the setup evaluation unit 108 identifies an evaluation threshold for setup time corresponding to the production operation estimated by the production operation estimation unit 102. In this case, for example, if the production operation estimation unit 102 estimates a no-exchange production method as the production operation, the setup evaluation unit 108 identifies an evaluation threshold for setup time corresponding to the no-exchange production method. The setup evaluation unit 108 also calculates the total setup time for the day being evaluated based on the status information of the production information. Then, the setup evaluation unit 108 identifies the maximum score at which the calculated setup time falls below the evaluation threshold corresponding to the estimated production operation. In other words, if the estimated production operation is a no-exchange production method and the calculated setup time is 750 seconds, the setup evaluation unit 108 evaluates the maximum score (11 points) at which the setup time of 750 seconds falls below the evaluation threshold corresponding to the no-exchange production method as the evaluation score for the retention rate.

[0041] The evaluation result output unit 110 displays the evaluation results, i.e., the evaluation scores, from the utilization rate evaluation unit 104, the dwell rate evaluation unit 106, and the setup change evaluation unit 108. Specifically, for example, the evaluation result output unit 110 displays the evaluation result screen 120 shown in Figure 8 on the monitor 122 of the information processing device 100. On the evaluation result screen 120, the evaluation scores for utilization rate (17 points), dwell rate (16 points), and setup change (11 points) are displayed as triangles in a graph.

[0042] For more details, an equilateral triangle (dotted line) is displayed with its vertex at the maximum score (20 points) for the three evaluation points: utilization rate, dwell rate, and setup changeover. Then, triangles (solid lines) are displayed with their vertices at positions corresponding to the evaluation points (17 points, 16 points, and 11 points) for utilization rate, dwell rate, and setup changeover, on the lines connecting the center of the equilateral triangle to each vertex. These solid-line triangles are graphs representing the evaluation points for utilization rate (17 points), dwell rate (16 points), and setup changeover (11 points). By displaying the evaluation results in graph form in this way, workers can visually understand the evaluation results.

[0043] Furthermore, on the evaluation results screen 120, next to the evaluation score displayed as a triangle graph, the scores for three evaluation categories (17 points, 16 points, and 11 points) for utilization rate, dwell rate, and setup changeover are displayed as percentages of the maximum score (20 points). In addition, as shown in Figures 5 to 7, the evaluation scores are divided into ranks A, B, C, D, and E in increments of 5 points, so the rank corresponding to the evaluation score is also displayed along with the percentage of the evaluation score. This allows the worker to understand the evaluation results numerically.

[0044] The evaluation results obtained in this manner are not only displayed on the monitor 122 but are also output to the customer. Specifically, if the evaluation result output unit 110 has transmission information such as the customer's address, it sends the image data of the evaluation result screen 120 to the customer. If the evaluation result output unit 110 does not have transmission information such as the customer's address, it prints the evaluation result screen 120 on paper, and the printed paper is sent to the customer.

[0045] In this way, by estimating production operations based on data included in production information, it becomes unnecessary to inquire about production operations from customers or to conduct on-site visits to customers to gather information on production operations, thus preventing delays in obtaining evaluation results. Furthermore, by changing the evaluation threshold according to the estimated production operations and evaluating the production line of the PCB work system, it becomes possible to appropriately evaluate the production line. In the evaluation of the production line, the operating rate of the PCB work system, the PCB retention rate, and the changeover are evaluated, allowing for an appropriate evaluation of the production line of the PCB work system.

[0046] Note that the substrate handling system 10 is an example of a work system. The information processing device 100 is an example of an information processing device.

[0047] Furthermore, the present invention is not limited to the above embodiments, and can be implemented in various forms with various modifications and improvements based on the knowledge of those skilled in the art. Specifically, for example, in the above embodiments, production operations are estimated based on production information of circuit boards produced in the board processing system, that is, information showing the production results of circuit boards in the board processing system. On the other hand, production operations may be estimated based on information showing the production schedule of circuit boards planned in the board processing system. It is also possible to evaluate the production schedule of circuit boards by changing the evaluation threshold according to the estimated production operations.

[0048] Furthermore, in the above embodiment, the evaluation threshold is changed according to the substrate production operation estimated based on production information, but the evaluation threshold may also be changed according to the substrate production operation obtained by another method. That is, for example, an operator may input the substrate production operation into the information processing device 100, and the evaluation threshold may be changed according to that production operation. Alternatively, for example, the information processing device 100 may acquire the substrate production operation from another device, and the evaluation threshold may be changed according to that production operation.

[0049] Furthermore, in the above embodiment, the production line of the circuit board handling system is evaluated using the operating rate, dwell time, and setup changeover time, but the production line may be evaluated by other evaluation methods. For example, the production line may be evaluated using the time that circuit boards dwell outside the circuit board handling system when they are brought into the system, the time that components are replenished, the time that the circuit board handling system is stopped due to errors, etc., and the component retention rate by the suction nozzle.

[0050] Furthermore, in the above embodiment, the production operation of the substrate is estimated based on the number of setup changes and whether or not the tape feeder is replaced, but the production operation of the substrate may also be estimated based on other information. For example, the production operation of the substrate may be estimated based on the utilization rate of component holders stored in the storage area, the ratio of supply devices that do not supply components during substrate production, the number of times component holders are replaced, etc. [Explanation of symbols]
