Description

[Technical Field]

[0001] The present invention relates to a production plan creation device, a production plan creation method, and a production plan creation program for creating a production plan for producing mounting boards. [Background technology]

[0002] When a factory having multiple mounting lines for producing mounted boards produces multiple board varieties, a method is known in which board varieties with high commonality in components are grouped together and the mounted boards are produced in groups, thereby reducing the number of setup changes and improving production efficiency (see, for example, Patent Document 1). Patent Document 1 discloses a production plan creation device that creates a production plan by creating multiple pre-registered groups in advance, each group containing multiple board varieties, and selecting a pattern whose evaluation value for production efficiency satisfies a predetermined condition from among the combination patterns of the pre-registered groups.

[0003] [Patent Document 1] Patent Publication No. 2021-44425 Summary of the Invention [Problem to be solved by the invention]

[0004] In factories that undertake the production of mounted boards for multiple customers, a production plan is created to create groups so that the multiple board varieties ordered by the multiple customers can be efficiently produced throughout the factory. However, with conventional technologies including Patent Document 1, although it is possible to create a production plan that allows the efficient production of multiple board varieties, there are cases where production is required that do not mix with mounted boards of other customers due to reasons such as the supply of components from one customer, and there is room for further improvement in order to achieve high mounting efficiency while preventing the mixed-in mounting boards of a specific customer with those of other customers.

[0005] Therefore, an object of the present invention is to provide a production plan creation apparatus, a production plan creation method, and a production plan creation program that can create a production plan in which specific substrate types are separated from other substrate types.

Means for Solving the Problems

[0006] The production plan creation apparatus of the present invention includes a display unit that displays information on a plurality of substrate types to be produced, a designated production group creation unit that groups the plurality of substrate types designated by a user among the plurality of substrate types displayed on the display unit as a designated production group, and a production order creation unit that creates a production order for the plurality of substrate types so that one designated production group is separated from other designated production groups.

[0007] The production plan creation method of the present invention displays information on a plurality of substrate types to be produced on a display unit, groups the plurality of substrate types designated by a user among the plurality of substrate types displayed on the display unit as a designated production group, and creates a production order for the plurality of substrate types so that one designated production group is separated from other designated production groups.

[0008] The production plan creation program of the present invention causes a computer to execute the production plan creation method according to claim 8.

Effects of the Invention

[0009] According to the present invention, a production plan in which specific substrate types are separated from other substrate types can be created.

[Figure 11] 1 is a flow diagram of a production plan creation method according to an embodiment of the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. The configurations, shapes, etc. described below are illustrative for explanation purposes and can be appropriately changed according to the specifications of the implementation system, implementation line, management computer (production plan creation device), component mounting device, etc. In the following, corresponding elements in all the drawings are denoted by the same reference numerals, and duplicate explanations are omitted. In FIG. 1 and in a part described later, as two axes orthogonal to each other in the horizontal plane, the X-axis in the substrate conveyance direction (the left-right direction in FIG. 1) and the Y-axis orthogonal to the substrate conveyance direction (the up-down direction in FIG. 1) are shown. In FIG. 2 and in a part described later, the Z-axis (the up-down direction in FIG. 2) is shown as the height direction orthogonal to the horizontal plane.

[0012] First, referring to FIG. 1, the configuration of the mounting system 1 will be described. The mounting system 1 is configured such that three mounting lines L1 to L3 arranged on the floor F are connected by a communication network 2, either wired or wireless, and are managed by a management computer 3. Each of the mounting lines L1 to L3 is configured by connecting a plurality of production devices including a printing device and a component mounting device, as will be described later, and has a function of producing a mounted substrate with components mounted on a substrate. Note that the number of mounting lines L1 to L3 provided in the mounting system 1 does not have to be three, and may be one, two, or four or more.

[0013] Next, referring to FIG. 1, the detailed configuration of the mounting lines L1 to L3 will be described. The mounting lines L1 to L3 have the same configuration. Hereinafter, the mounting line L1 will be described. The mounting line L1 is configured by connecting production devices such as a printing device M1, component mounting devices M2 to M5, and a reflow device M6 in series in order from the upstream (left side of the paper surface) to the downstream (right side of the paper surface) in the substrate conveyance direction. The production devices are connected to the management computer 3 via the communication network 2. Note that the mounting line L1 is a group of production devices connected via the communication network 2, and the production devices do not have to be physically connected to each other.

[0014] In FIG. 1, the printing device M1 has a function of printing paste-like cream solder onto a substrate via a screen mask. The component mounting devices M2 to M5 have a function of picking up components supplied from a component supply unit by suction nozzles attached to a mounting head, transferring them to the mounting positions on the substrate onto which the cream solder has been printed, and mounting them. The reflow device M6 has a function of heating the substrate on which components are mounted, melting the cream solder, and then solidifying it to solder the components to the substrate.

[0015] The management computer 3 executes processes such as production management of the mounting substrates produced on the mounting lines L1 to L3, creation and transmission of programs and data necessary for the production of the mounting substrates for each production device. Further, the management computer 3 functions as a production plan creation device that creates a production plan for producing mounting substrates of a plurality of substrate types on the mounting lines L1 to L3.

[0016] Next, with reference to FIG. 2, the configuration of the component mounting devices M2 to M5 will be described. Component supply units 11 are provided on the front side and the rear side of the component mounting devices M2 to M5, respectively. A cart 14 with a feeder base 13 having a plurality of slots in parallel and with feeders 12 mounted in each slot is disposed on the upper part of the component supply unit 11. In the cart 14, a plurality of reels 15 for winding and storing a carrier tape for storing components are held in parallel below the feeder 12. The feeder 12 supplies the components stored in the carrier tape to the component mounting devices M2 to M5 in order while transporting the carrier tape drawn out from the reel 15 inside.

[0017] Inside the component mounting devices M2 to M5, a mounting head 16 with suction nozzles 17 for holding components is disposed. The mounting head 16 is moved between the component supply unit 11 and the substrate held at the mounting operation position by a lane for transporting the substrate by a head movement mechanism (not shown). In this way, a component mounting operation is performed in which the components taken out by the suction nozzles 17 from the feeder 12 of the component supply unit 11 are mounted at the mounting positions on the substrate.

[0018] In FIG. 1, when changing the setup for changing the substrate types produced on the mounting lines L1 to L3, in the printing apparatus M1, the mounted screen mask is replaced with a screen mask corresponding to the substrate type after the change, and a setup operation for replacing the cream solder is executed. Also, at the time of setup change, in the component mounting apparatuses M2 to M5, the feeders 12 and reels 15 are replaced so that the types of components supplied from the component supply unit 11 correspond to the substrate type after the change, and a setup operation for replacing the mounting head 16 and the suction nozzle 17 is executed.

[0019] Next, referring to FIG. 3, the configuration of the information processing system of the management computer 3 will be described. Here, among the plurality of functions provided in the management computer 3, the configuration related to the function as a production plan creation apparatus that creates a production plan for producing mounted substrates of a plurality of substrate types on the mounting lines L1 to L3 will be described. In particular, the function as a production plan creation apparatus that creates a production plan (reorganized production plan) that separates the substrate types of a specific customer from those of other customers will be described.

[0020] In FIG. 3, the management computer 3 includes a processing device 20, a storage unit 27 which is a storage device, an input unit 34, a display unit 35, and a communication unit 36. The processing device 20 is a data processing device such as a CPU, and includes an acquisition unit 21, a designated production group creation unit 22, a production order creation unit 23, a designated component setting unit 24, an extended production group creation unit 25, and a delivery date determination unit 26 as internal processing units.

[0021] The storage unit 27 stores production plan information 28, substrate type information 29, mounting line information 30, designated production group information 31, reorganized production plan information 32, extended production group information 33, and the like. Note that the management computer 3 does not necessarily have to be configured by a single computer, and may be configured by a plurality of devices. For example, all or part of the storage unit 27 and the processing device 20 may be provided in the cloud.

[0022] In FIG. 3, the input unit 34 is an input device such as a keyboard, a touch panel, or a mouse, and is used when an operation command or data is input. The display unit 35 is a display device such as a liquid crystal panel, and displays various data stored in the storage unit, as well as various information such as an operation screen and an input screen for the operation by the input unit 34. The communication unit 36 is a communication interface, and transmits and receives data to and from the printing device M1, the component mounting devices M2 to M5, and the reflow device M6 that constitute the mounting lines L1 to L3 via the communication network 2.

[0023] The production plan information 28 stores a production plan for producing mounting substrates of a plurality of substrate types on the mounting lines L1 to L3 for a predetermined period (for example, one month), which is created by a production plan creation unit or a production plan creation device provided in the management computer 3 (not shown). The production plan includes information for specifying the substrate types of the mounting substrates produced on the mounting lines L1 to L3, the production quantity of the mounting substrates for each substrate type, the production order of the plurality of substrate types, the production delivery date, and the like. In this embodiment, the production plan information 28 stores a production plan created so that mounting substrates of a plurality of substrate types can be efficiently produced on the plurality of mounting lines L1 to L3 without considering the differences in customers who are the order sources of the mounting substrates.

[0024] In FIG. 3, the substrate type information 29 stores, for each substrate type of the mounting substrates produced on the mounting lines L1 to L3, a mounting program used in each of the component mounting devices M2 to M5, which is created by a mounting program creation unit or a mounting program creation device provided in the management computer 3 (not shown). Each mounting program stores information such as the size of the substrate, the types of components mounted on the substrate, the mounting positions (XY coordinates) of the components, and the arrangement information (component arrangement) of the feeders 12 that supply the components arranged on the carriage 14 mounted on the component supply unit 11. Further, the substrate type information 29 stores information for specifying whether the components mounted on the substrate are the specified components described later.

[0025] The implementation line information 30 includes the configurations of implementation lines L1 to L3, and the specifications of the printing device M1, component mounting devices M2 to M5, and reflow device M6 that constitute the implementation lines L1 to L3. The specifications of the component mounting devices M2 to M5 include information regarding the configurations of the component mounting devices M2 to M5, such as the types and numbers of feeders 12 that can be mounted on the component supply unit 11, the types and numbers of mount heads 16 that can be mounted, and the number of lanes for transporting the substrate, and the production capacity (such as the number of components that can be mounted on the substrate per unit time).

[0026] In FIG. 3, the acquisition unit 21 acquires the production plan for the period (target period) for which the production plan is to be reorganized in consideration of a specific customer from the production plan information 28. The target period is specified, for example, by an administrator (user) who manages the production on the floor F where the implementation lines L1 to L3 are arranged, using a target period setting screen (not shown) displayed on the display unit 35. Further, the acquisition unit 21 acquires the substrate type information including the mounting program corresponding to the substrate type of the mounting substrate produced during the target period from the substrate type information 29.

[0027] The designated production group creation unit 22 groups a plurality of substrate types specified by the user (administrator) among the plurality of substrate types as a designated production group, and stores the information regarding the designated production group in the storage unit 27 as designated production group information 31. Hereinafter, the substrate type specified by the user is referred to as the "designated substrate type". For example, the designated substrate type is specified when it is necessary to avoid confusion with the mounting substrates of other customers, such as when dedicated components or dedicated cream solder are provided for the production of the mounting substrates of a specific customer.

[0028] In the present embodiment, the designated production group creation unit 22 will be described by an example in which the substrate type information addition screen (FIG. 4) and the designated production group setting screen (FIG. 5) are displayed on the display unit 35, and the administrator sets the designated substrate type while operating the input unit 34. That is, the designated production group creation unit 22 groups a plurality of designated substrate types specified by the administrator among the plurality of substrate types displayed on the display unit 35 as a designated production group.

[0029] 4, an example of the board variety information addition screen 40 that the designated production group creation unit 22 has displayed on the display unit 35 will be described. The board variety information addition screen 40 displays an additional setting frame 41, a cancel button 42, and a confirm button 43. The additional setting frame 41 displays a designated production group information cell and a designated part information cell for each board variety included in the production plan for the target period.

[0030] Operating (clicking) the button displayed in the designated production group information cell opens the designated production group setting screen (Figure 5), which is used to add information about the designated production group to the corresponding board variety. Operating (clicking) the button displayed in the designated component information cell opens the designated component setting screen (Figure 6), which is used to add information about the designated component to the corresponding board variety. Once the designated production group information has been set, the designated production group name will be displayed in the designated production group information cell. Also, once the designated component information has been set, "Yes" will be displayed in the designated component information cell.

[0031] In Figure 4, the seven board types included in the production plan for the target period are board type A1, board type A2, board type A3, board type B1, board type B2, board type X1, and board type X2. The additional setting frame 41 shown in Figure 4 shows a state in which the administrator is adding information, with board type A1 and board type A2 set to designated production group A. Furthermore, designated part information has been set for board type A2.

[0032] When the cancel button 42 is operated, the settings of the information about the designated production group and the information about the designated parts set in the additional setting frame 41 are canceled. When the confirm button 43 is operated, the information about the designated production group and the information about the designated parts are confirmed as the information set in the additional setting frame 41. In this manner, the display unit 35 displays information about the multiple board varieties to be produced. Note that for board varieties that contain the same parts as the set designated parts, the color of the text or frame of the board variety displayed in the additional setting frame 41 may be changed, for example, to provide visual assistance in determining whether or not to add the board variety to the designated production group.

[0033] Next, referring to FIG. 5, an example of the designated production group setting screen 44 displayed by the designated production group creation unit 22 on the display unit 35 will be described. This example shows the designated production group setting screen 44 displayed by operating the button 41a displayed in the designated production group information cell of the substrate type A3 in the additional setting frame 41 on the substrate type information addition screen 40 shown in FIG. 4.

[0034] On the designated production group setting screen 44, a substrate type name display frame 45, a designated production group designation frame 46, an add button 47, a cancel button 48, and a determination button 49 are displayed. In the substrate type name display frame 45, the substrate type name of the substrate type for which information regarding the designated production group is added (or changed) is displayed. Note that when a plurality of designated production group information cells are selected in the additional setting frame 41 of the substrate type information addition screen 40 to display the designated production group setting screen 44, information regarding the same designated production group can be added for the plurality of selected substrate types.

[0035] In FIG. 5, in the designated production group designation frame 46, the designated production group names of the designated production groups that can be designated for the substrate type (in this example, substrate type A3) displayed in the substrate type name display frame 45 are displayed as a list. When the designated production group name displayed in the designated production group designation frame 46 is operated (clicked), the designated production group to be designated is selected. In this example, "A" and "B" are displayed as the designated production group names, and "Designated Production Group A" is selected (indicated by hatching in the figure).

[0036] When the add button 47 is operated, a screen for adding a specified production group to the specified production group designation frame 46 is opened, and a specified production group that can be specified can be added to the specified production group designation frame 46. When the cancel button 48 is operated, the selection of the specified production group in the specified production group designation frame 46 is canceled. When the OK button 49 is operated, information regarding the specified production group (A) selected in the specified production group designation frame 46 is added to the substrate type (A3) displayed in the substrate type name display frame 45, and the specified production group setting screen 44 is closed.

[0037] Next, with reference to FIG. 7, an example of the specified production group information 31 will be described. Here, the specified production group information 31 set using the substrate type information addition screen 40 shown in FIG. 4 will be described as an example. In the specified production group information 31, information for specifying the specified production group is stored in the specified production group information column 56 corresponding to the substrate type in the substrate type column 55. In this example, "A" in the specified production group information column 56 indicates belonging to the "specified production group A", and "B" indicates belonging to the "specified production group B". A substrate type with a blank specified production group information column 56 indicates an unspecified substrate type that has not been specified as a specified substrate type.

[0038] In this example, substrate types A1, A2, and A3 are grouped as the specified production group A. Also, substrate types B1 and B2 are grouped as the specified production group B. Further, substrate types X1 and X2 are unspecified substrate types.

[0039] In FIG. 3, the production order creation unit 23 creates a rearranged production plan in which the production order of a plurality of substrate types is created such that the substrate types of one specified production group included in the production plan for the specified period are separated from the substrate types of other specified production groups based on the substrate type information 29, the mounting line information 30, and the specified production group information 31. The created rearranged production plan is stored in the storage unit 27 as the rearranged production plan information 32.

[0040] Next, an example of a reorganized production plan created by the production sequence creation unit 23 will be described with reference to Fig. 9. Fig. 9 is an example of a reorganized production plan created by the production sequence creation unit 23 for board type A1, board type A2, board type B1, and board type B2 out of the board types included in the designated production group information 31 shown in Fig. 7.

[0041] 9(a) is an example of a reorganized production plan created under the condition that board types A1, A2, B1, and B2 are produced on a single-lane mounting line L1, which has one lane for transporting boards. The production sequence creation unit 23 creates a component arrangement for component mounting devices M2 to M5 based on the similarity of components between board type A1 and board type A2 of designated production group A. In this example, the production sequence creation unit 23 creates a production sequence in a common arrangement that enables mounted boards of board type A1 and mounted boards of board type A2 to be produced consecutively without performing setup change work such as replacing feeders 12.

[0042] Similarly, the production sequence creation unit 23 creates a component arrangement based on the similarity of components between board type B1 and board type B2 of designated production group B. In this example, a production sequence is created in which board type B1 and board type B2 are produced in a common arrangement. In addition, the production sequence creation unit 23 creates a production sequence in which mounted boards are produced in the order of designated production group A and then designated production group B. Then, the production sequence creation unit 23 creates a plan to execute a changeover operation to change the component arrangement of component mounting devices M2 to M5 between board type A2 and board type B1 to the common arrangement of designated production group B.

[0043] Furthermore, even when the same types of components are mounted on board types A1 and A2 and board types B1 and B2, if the common components are designated components (described later), the common components are replaced during the changeover work. In other words, the common components are changed from components exclusive to designated production group A to components exclusive to designated production group B.

[0044] In this way, a plurality of substrate types A1, A2, B1, and B2 are produced in one lane of the mounting line L1. The production order creation unit 23 executes a setup change operation between the substrate type A2 of one designated production group (designated production group A) and the substrate type B1 of another designated production group (designated production group B), and creates a production order that is separated so that there is no confusion of designated parts between one designated production group and another designated production group. Further, the production order creation unit 23 creates a group with a common arrangement within the designated production group based on the similarity of parts of a plurality of substrate types (for example, substrate types A1 to A3) belonging to the same designated production group (for example, designated production group A), and creates a production order.

[0045] Figure 9(b) is an example of a reorganized production plan created under the condition of producing substrate types A1, A2, B1, and B2 in a dual-lane mounting line L1 having two lanes for transporting substrates. The production order creation unit 23 creates a production order in which the substrate type A1 and the substrate type A2 of the designated production group A are produced in a common arrangement in lane 1, and the substrate type B1 and the substrate type B2 of the designated production group B are produced in a common arrangement in lane 2.

[0046] In this way, a plurality of substrate types A1, A2, B1, and B2 are produced in a plurality (two) of lanes (lane 1, lane 2) of the mounting line L1. The production order creation unit 23 creates a production order that is separated so that the substrate types A1 and A2 of one designated production group (designated production group A) are not produced in the same lane as the substrate types B1 and B2 of another designated production group (designated production group B).

[0047] Figure 9(c) is an example of a reorganized production plan created under the condition of producing substrate types A1, A2, B1, and B2 in a single-lane mounting line L1 and a single-lane mounting line L2. The production order creation unit 23 creates a production order in which the substrate type A1 and the substrate type A2 of the designated production group A are produced in a common arrangement in the mounting line L1, and the substrate type B1 and the substrate type B2 of the designated production group B are produced in a common arrangement in the mounting line L2.

[0048] In this way, a plurality of substrate types A1, A2, B1, and B2 are produced on a plurality (two) of mounting lines L1 and L2, and the production order creation unit 23 creates a production order in which the substrate types A1 and A2 of one designated production group (designated production group A) are separated so as not to be produced on the same mounting lines L1 and L2 as the substrate types B1 and B2 of another designated production group (designated production group B).

[0049] In FIG. 3, the designated component setting unit 24 stores, in the substrate type information 29, as designated components, components that are prohibited from being used in substrate types outside the designated production group specified by the user (administrator) among the components used in the production of the substrate types (designated substrate types) of the designated production group. In this embodiment, the designated component setting unit 24 will be described by way of an example in which a designated component setting screen (FIG. 6) operated by the administrator is displayed on the display unit 35. That is, the designated component setting unit 24 sets, as designated components, the components specified by the administrator among the components used in the production of the substrate types displayed on the display unit 35 for the designated production group.

[0050] Next, with reference to FIG. 6, an example of the designated component setting screen 50 displayed by the designated component setting unit 24 on the display unit 35 will be described. This example shows the substrate type information addition screen 40 displayed by operating the button 41b displayed in the designated component information cell of the substrate type A3 in the addition setting frame 41 in the substrate type information addition screen 40 shown in FIG. 4.

[0051] The designated component setting screen 50 displays a substrate type name display frame 51, a designated component designation frame 52, a cancel button 53, and a determination button 54. The substrate type name display frame 51 displays the substrate type name of the substrate type for which information regarding the designated component is added (or changed). In the designated component designation frame 52, check buttons for selecting that they are designated components are displayed for each type of component used in the production of the substrate type displayed in the substrate type name display frame 51 (in this example, the substrate type A3). By operating the scroll bar, types of components not displayed in the substrate type name display frame 51 are displayed.

[0052] In FIG. 6, in this example, among the components used in the production of substrate type A3, component d and component e are selected as the designated components. When the cancel button 53 is operated, the selection of the designated components in the designated component designation frame 52 is canceled. When the decision button 54 is operated, the designated component setting unit 24 adds information regarding the designated components (d, e) to the substrate type information 29 of the substrate type (A3) displayed in the substrate type name display frame 51, and the designated component setting screen 50 is closed.

[0053] Next, referring to FIG. 8, an example of the information regarding the designated components included in the substrate type information 29 will be described. In FIG. 8, for each part name 57, part information 58 is displayed to identify whether it is used in the production of substrate type A3, substrate type X1, and substrate type X2, or is designated as a designated component. In this example, for substrate type A3 belonging to the designated production group A, parts a to e are used, and parts d and e are designated as designated components. Among the parts used in the production of substrate type X1, which is a non-designated substrate type, parts a and b are common to the parts used in the production of substrate type A3, while parts f and g are not. Among the parts used in the production of substrate type X2, which is a non-designated substrate type, parts c to e are common to the parts used in the production of substrate type A3, while part g is not.

[0054] In FIG. 3, the production order creation unit 23 creates a production order in which the number of parts commonly used in production increases when switching between the designated production group and the non-designated substrate types, which are the remaining substrate types excluding the substrate types of the plurality of designated production groups. Further, when switching between the designated production group and the non-designated substrate types, the production order creation unit 23 creates a production order that does not include designated components that prohibit the use outside the designated production group among the parts commonly used in production.

[0055] Referring to FIG. 8, the substrate type X2, which is an off-specification substrate type, has more components in common with the substrate type A3 than the substrate type X1, which is also an off-specification substrate type. Therefore, if the components used in the production of the substrate type X2 do not include the specified components of the substrate type A3, the production order creation unit 23 executes a setup change operation after the production of the substrate type A3 in the specified production group A, and creates a reorganized production plan for switching to the substrate type X2 in the production order. Also, if the components used in the production of the substrate type X2 include the specified components of the substrate type A3 and do not include them in the substrate type X1 (example in FIG. 8), the production order creation unit 23 executes a setup change operation after the production of the substrate type A3 in the specified production group A, and creates a reorganized production plan for switching to the substrate type X1 in the production order.

[0056] In FIG. 3, the extended production group creation unit 25 groups the substrate types of the specified production group and the off-specification substrate types excluding the substrate types of the plurality of specified production groups, excluding the special off-specification substrate types that include the specified components prohibited from being used outside the specified production group, based on the similarity of the components mounted on the mounting substrate, and summarizes them as an extended production group, and stores them in the storage unit 27 as the extended production group information 33. Then, the production order creation unit 23 creates a reorganized production plan in which the production order of a plurality of substrate types is created so that one extended production group is separated from other specified groups and other extended production groups.

[0057] Next, referring to FIG. 10, a specific example of the creation of an extended production group by the extended production group creation unit 25 and the creation of a reorganized production plan based on the extended production group by the production order creation unit 23 will be described. FIG. 10 is an example of a reorganized production plan created under the conditions of producing the substrate types A1 to A3, B1 to B2, X1 to X2 based on the information regarding the specified components shown in FIG. 8 on the single-lane mounting line L1 and the single-lane mounting line L2.

[0058] Regarding the information on the specified parts shown in FIG. 8, for the substrate type X1 which is an unspecified substrate type, it does not include the specified parts used in the substrate types A1 to A3 of the specified production group A nor the specified parts used in the substrate types B1 to B2 of the specified production group B. On the other hand, for the substrate type X2 which is an unspecified substrate type, it includes the same parts d and e as the specified parts used in the substrate types A1 to A3 of the specified production group A, but does not include the specified parts used in the substrate types B1 to B2 of the specified production group B. That is, the substrate type X2 becomes a special unspecified substrate type for the specified production group A, but does not become a special unspecified substrate type for the specified production group B. Also, the substrate type X1 does not become a special unspecified substrate type for either the specified production group A or the specified production group B.

[0059] In FIG. 10, the extended production group creation unit 25 groups together the substrate types A1 to A3 of the specified production group A and the substrate type X1 which is an unspecified substrate type that is not a special unspecified substrate type as the extended production group Q based on the similarity of parts. Also, the extended production group creation unit 25 groups together the substrate types B1 to B2 of the specified production group B and the substrate type X2 which is an unspecified substrate type that is not a special unspecified substrate type as the extended production group R based on the similarity of parts.

[0060] In FIG. 10, the production order creation unit 23 assigns the extended production group Q to the mounting line L1 and assigns the extended production group R to the mounting line L2. Thereby, one specified production group (specified production group A) and another specified production group (specified production group B) and the special unspecified substrate type (substrate type X2) are separated so as not to be produced on the same mounting line (mounting line L1).

[0061] Furthermore, based on the similarity of the components of substrate types A1 to A3 and substrate type X1 in the extended production group Q, the production order creation unit 23 produces substrate types A1 and A2 in a common arrangement, produces substrate types A3 and X1 in a common arrangement, and creates a production order in which a setup change operation is executed between substrate types A2 and A3. Also, based on the similarity of the components of substrate types B1 to B2 and substrate type X2 in the extended production group R, the production order creation unit 23 creates a production order in which substrate types B1 to B2 and substrate type X2 are produced in a common arrangement. As a result, a production plan can be created in which specific substrate types A1 to A3 are separated from other substrate types B1 to B2 and X2.

[0062] In FIG. 3, the delivery date determination unit 26 determines whether the created reorganized production plan satisfies the production delivery date for each substrate type based on the production plan information 28, the substrate type information 29, the mounting line information 30, and the reorganized production plan information 32. For example, the delivery date determination unit 26 calculates the cycle time for each substrate type based on the mounting program included in the substrate type information 29, calculates the production time from the production quantity for each substrate type, and determines whether the expected production completion time of the substrate type satisfies the production delivery date.

[0063] Also, the delivery date determination unit 26 simulates the operation of the component mounting operation based on the specifications of the component mounting apparatuses M2 to M5 (such as the substrate transfer speed and the moving speed of the mounting head 16) included in the mounting line information 30 to calculate the production time, and determines whether the expected production completion time of the substrate type satisfies the production delivery date. When the delivery date determination unit 26 determines that the created reorganized production plan does not meet the delivery date, it causes the display unit 35 to notify of that fact.

[0064] Next, a production plan creation method (production plan creation program) for creating a production plan (reorganized production plan) that separates the substrate types of a specific customer from those of other customers will be described along the flow of FIG. 11. First, the acquisition unit 21 acquires the production plan for the target period from the production plan information 28 (ST1: production plan acquisition step). Next, the designated production group creation unit 22 causes the display unit 35 to display information on a plurality of substrate types to be produced included in the production plan for the target period (ST2: substrate type display step). For example, the designated production group creation unit 22 displays a plurality of substrate types on the substrate type information addition screen 40 (FIG. 4).

[0065] Next, the designated production group creation unit 22 causes the user (administrator) to designate, as a designated production group, the substrate type to be separated from other substrate types among the plurality of substrate types displayed on the display unit 35 (ST3: designated production group designation step). For example, the user designates the designated production group using the designated production group setting screen 44 (FIG. 5).

[0066] In FIG. 11, next, the designated component setting unit 24 sets, as designated components, the components that are used in the production of the substrate types of the designated production group displayed on the display unit 35 and are prohibited from being used in substrate types outside the designated production group designated by the user (ST4: designated component designation step). For example, the user designates the designated components using the designated component setting screen 50 (FIG. 6).

[0067] Next, the designated production group creation unit 22 creates a designated production group by grouping a plurality of substrate types designated by the user (administrator) among the plurality of substrate types displayed on the display unit 35 (ST5: designated production group creation step). Next, when designated components are set (Yes in ST6), the extended production group creation unit 25 groups the non-designated substrate types excluding the substrate types of the designated production group and the non-special-designated substrate types including the designated components based on the similarity of the components to create an extended production group (ST7: extended production group creation step). When designated components are not set (No in ST6), the extended production group creation step (ST7) is skipped.

[0068] In FIG. 11, next, the production order creation unit 23 creates a reorganized production plan in which the production order of a plurality of substrate types is created such that one designated production group is separated from other designated production groups and one extended production group is separated from other designated production groups and other extended production groups (ST8: reorganized production plan creation step). Next, the delivery date determination unit 26 determines whether the created reorganized production plan meets the production delivery date (ST9: delivery date determination step). When it is determined that the delivery date is not met (No in ST9), the delivery date determination unit 26 causes the display unit 35 to notify of this fact (ST10: notification step). When it is determined that the delivery date is met (Yes in ST9), the notification step (ST10) is skipped and the creation of the reorganized production plan is terminated.

[0069] Note that when it is determined that the delivery date is not met (No in ST9), the reorganized production plan creation step (ST8) may be repeatedly executed until a reorganized production plan that meets the delivery date is created.

[0070] As described above, the management computer 3 of the present embodiment includes a display unit 35 that displays information on a plurality of substrate types to be produced, and a designated production group creation unit 22 that groups a plurality of substrate types A1 to A3 and B1 to B2 designated by a user (administrator) among the plurality of substrate types displayed on the display unit 35 as designated production groups A and B, and a production order creation unit 23 that creates the production order of a plurality of substrate types A1 to A3 and B1 to B2 such that one designated production group A is separated from other designated production groups B. It is a production plan creation device. Thereby, a production plan in which a specific substrate type is separated from other substrate types can be created.
