Description

  The present invention relates to a production management apparatus and a production management method for managing a wire harness arranged in a vehicle or the like to be produced with high productivity.

  The wire harnesses for connecting the various electrical components mounted in the vehicle are the same number of electric wires and parts according to the specifications (grade, presence or absence of optional equipment, etc.) of each vehicle, even in the same vehicle type The number of and the routing routes differ. Therefore, a plurality of types of sub-harnesses to be a part of the wire harness are prepared, and the sub-harnesses according to various specifications are appropriately selected and assembled to produce a wire harness.

  As a production control method of a wire harness, what was disclosed by patent document 1, for example is known. In Patent Document 1, a shared circuit common to each vehicle type and a dedicated circuit selected by a grade or an optional device are divided and created, and the shared circuit and the dedicated circuit can be connected by a branch connector. Then, a desired dedicated circuit is connected to the shared circuit to produce a wire harness conforming to the specification.

  For example, in the case where there are four selectable electrical components, the combination of the presence / absence of each electrical component and the connection with the common circuit requires sixteen harnesses. By using the above, it is only necessary to manage one common circuit and four types of dedicated circuits, and it is possible to reduce the production number and simplify management.

  However, in the conventional example disclosed in Patent Document 1 described above, there is a problem that productivity is reduced because a shared circuit is manufactured by combining a dedicated circuit. For example, in the case of producing a wire harness for connecting three dedicated circuits a, b and c to the shared circuit A, three assembly operations are required for the shared circuit A. Usually, when the assembly work of the wire harness is performed in a series of flow operations, the dedicated circuit a is first connected to the shared circuit A, the dedicated circuit b is connected in the downstream process, and then further downstream It is necessary to connect the dedicated circuit c in the process on the side. Since this assembly operation is usually performed manually, much labor is required, resulting in a decrease in productivity.

Description of the First Embodiment
FIG. 1 is a block diagram showing the configuration of a production control device for a wire harness according to an embodiment of the present invention. The production management device is a device that supports the production design of a wire harness that connects the respective electrical components mounted in the vehicle. As shown in FIG. 1, the production management apparatus 100 displays an input unit 11 to which order information of a wire harness is input, a control unit 12 that controls the entire apparatus, and a connection index calculated by the control unit 12. And a display unit 13 (information presentation unit) for notifying the worker. In the present embodiment, the display unit 13 such as a display is described as an example of the information presentation unit, but it is also possible to use a presentation device that presents the operator with information other than images such as voice. .

  The wire harness is formed by connecting a plurality of sub-harnesses to one another. That is, the wire harness is divided into a plurality of sub-harnesses, and is formed by connecting and assembling the respective sub-harnesses. At this time, the sub-harness is classified into a base sub-harness required regardless of the grade of the vehicle and the presence or absence of the optional device, and an optional sub-harness necessary according to the presence or absence of the grade or the optional device. Therefore, the wire harness is formed by connecting at least one optional sub harness to the base sub harness. In the following, the base sub harness is abbreviated as "base sub" and the option sub harness is abbreviated as "option sub".

  In the input unit 11 illustrated in FIG. 1, order information of a wire harness specified from an electrical component name or an electrical component name is input by an upstream device or a worker. The order information includes information of a base sub and a plurality of option subs connected to the base sub. The base sub is, for example, a common harness for each type of vehicle, and includes at least one electric wire and at least one connector. In addition, the optional sub is a harness that differs depending on the grade of the vehicle and optional equipment (electrical components mounted on the vehicle), for example, a navigation device, an audio device, etc., and includes at least one electric wire and at least one connector There is.

  In the production management apparatus 100 according to the present embodiment, when order information is input, a base sub based on the order information and a plurality of option subs are selected, and connectors selected by each selected option sub are connected. In consideration of commonality and commonality of routings, option subs having commonality are sorted into the same group. Then, information on the sorted groups is displayed on the display unit 13 and notified to the worker. By recognizing this information, the worker can create an indicator of the task of connecting the option subs of the sorted groups in advance and connecting the option sub after connection to the base sub, Improve the workability when connecting the sub to the base sub.

  The control unit 12 includes a connection information storage unit 121, a sorting calculation unit 122, a sorting data storage unit 123, a harness selection unit 124, and a connection information recognition unit 125. The control unit 12 is configured, for example, as an integrated computer including storage means such as a central processing unit (CPU), a RAM, a ROM, and a hard disk.

  The harness selection unit 124 selects, based on the order information input from the input unit 11, a base sub and an option sub to be used when producing a wire harness. The information on the option sub is determined by the grade of the vehicle and the electrical components set as options. Furthermore, the harness specified from the determined electrical component is determined.

  The connection information storage unit 121 stores connection information of electric wires included in each base sub and each option sub, and a “circuit list” which is routing information to be routed. Details will be described later.

  The connection information recognition unit 125 reads, from the connection information storage unit 121, the connection information of each connector and electric wire included in the base sub and option sub selected by the harness selection unit 124 and recognizes the connection information.

  The sorting calculation unit 122 refers to the connection information of each connector and wire recognized by the connection information recognition unit 125, and the information on the end of each wire included in the selected option sub (first end described later) , Information of the second end portion), extract the common part of the electric wire included in each option sub, and determine whether or not to sort as the same group.

  The sorting data storage unit 123 stores sorting data calculated by the sorting calculation unit 122 in the past. For example, when option subs a and c are sorted as the same group, this data is stored. When option subs a and c are input next time or later, these are recognized as the same group without performing the sorting operation.

  Next, connection information of each option sub stored in the connection information storage unit 121 will be described. 3 is an explanatory view showing the connection state of the option sub a and the circuit list, FIG. 4 is an explanatory view showing the connection state of the option sub c and the circuit list, and FIG. 5 is a connection state of the option sub e and the circuit list FIG. In the circuit list, information on one end (hereinafter referred to as "first end") of the electric wire included in each option sub, information on the other end (hereinafter referred to as "second end"), and electric wire Contains optional sub information to which

  Specifically, the electric wire L1 shown in FIG. 3 is wired from the connector HC1 to the connector HC3 and connected, and belongs to the option sub a. Further, the electric wire L6 shown in FIG. 4 is wired from the connector HC4 to the connector HC5 and connected, and belongs to the option sub c. The electric wire L10 shown in FIG. 5 is wired from the connector HC6 to the connector HC7 and connected, and belongs to the option sub e.

Next, an operation procedure of grouping of each option sub by the control unit 12 will be described with reference to a flowchart shown in FIG.
First, in step S11 of FIG. 7, the harness selection unit 124 waits for an order by the input unit 11. When order information is input from the input unit 11, in step S12, the harness selection unit 124 reads base sub and option sub information from the input order information (harness selection step). At this time, the information on the option sub is determined by the grade of the vehicle and the electrical components set as options. In the present embodiment, as shown in FIG. 2A, a case where a base sub A and three option subs a, c, and e are input will be described. For example, a harness for connecting to a navigation device, a keyless entry system, an audio device or the like can be mentioned as an optional sub.

  In step S13, the connection information recognition unit 125 reads the connection information of each option sub stored in the connection information storage unit 121 (connection information recognition step). In this process, the circuit list shown in FIGS. 3 to 5 is recognized. In the present embodiment, since three option subs a, c and e are set, the circuit list shown in FIGS. 3 to 5 is recognized. As shown in FIG. 3, the option sub-a includes three connectors HC1, HC2, HC3 and five electric wires L1 to L5. As shown in the circuit list, the electric wires L1 and L2 are wired between the connectors HC1 and HC3, and the electric wires L3 to L5 are wired between the connectors HC1 and HC2.

  As shown in FIG. 4, the option sub c includes two connectors HC4 and HC5 and four electric wires L6 to L9. Then, as shown in the circuit list, the wires L6 and L7 are wired between the connectors HC4 and HC5, the wire L8 is wired between the connectors HC4 and HC7, and the wire L9 is a connector It is routed between HC5 and HC3. At this time, since the connector HC7 is included in the option sub e shown in FIG. 5 and the connector HC3 is included in the option sub a shown in FIG. 3, the second end of the electric wire L8 is used as the connection terminal TB-8. The second end of the electric wire L9 is a connection terminal TB-9.

  As shown in FIG. 5, the option sub e includes two connectors HC6 and HC7 and four electric wires L10 to L13. Then, as shown in the circuit list, the electric wires L10 and L11 are arranged between the connectors HC6 and HC7, the electric wire L12 is arranged between the connectors HC6 and HC2, and the electric wire L13 is a connector It is routed between HC6 and HC3. At this time, since the connectors HC2 and HC3 are included in the optional sub-a shown in FIG. 3, the second end of the electric wire L12 is used as the connection terminal TB-12, and the second end of the electric wire L13 is connected Terminal TB-13.

  In step S14, the sorting operation unit 122 determines the commonality of the connectors connected to the wires included in each of the option subs a, c, and e, and the commonality of the wiring routes, and the commonality among the connectors or the wiring routes. If there is a group, it is sorted as the same group (sorting operation process). In the present embodiment, as shown in FIGS. 3 to 5, since the option subs a, c, and e have common connectors to which the respective electric wires are connected, the sorting operation unit 122 includes the option subs a, c, and e. Sort c and e into the same group. Then, the sorting information is displayed on the display unit 13.

  FIG. 6 is an explanatory view showing a state in which three option subs a, c and e are connected. As shown in FIG. 6, the connection terminal TB-12 attached to the electric wire L12 of the harness e is connected to the connector HC2 of the harness a, and the connection terminal TB-13 attached to the electric wire L13 of the harness e is the connector of the harness a Connected to HC3. The connection terminal TB-8 attached to the electric wire L8 of the harness c is connected to the connector HC7 of the harness e, and the connection terminal TB-9 attached to the electric wire L9 of the harness c is connected to the connector HC3 of the harness a . That is, by sorting the three option subs a, c, and e into the same group, it is possible to perform the preceding connection at four places.

  In step S15, the sorting calculation unit 122 stores grouping information indicating that the three option subs a, c, and e are sorted into the same group in the sorting data storage unit 123. Moreover, it displays on the display part 13 (information presentation process). By using this grouping information, the operator can be made aware of the combination of optional subs. Further, when the same option sub a, c, e is selected next time or later, it is possible to recognize that these belong to the same group without performing the sorting operation again.

  As described above, in the three optional subs a, c, and e, after connecting the wires L8, L9, L12, and L13 to the connectors in advance, connecting them to the base sub A is more efficient in producing the wire harness. Good. That is, since the operation of connecting three option subs a, c and e in advance can be performed using an automation device using a machine, the labor of connecting the option subs is reduced. . On the other hand, when connecting three option subs a, c and e to the base sub A, the first worker connects the option sub a to the base sub A, and then As the second worker on the downstream side connects the option sub c, and the third worker on the downstream side connects the option sub e, a lot of manual work is required and the labor is excessive. It becomes.

  The production management apparatus 100 according to the present embodiment determines whether the three option subs a, c, e are to be sorted as the same group, and displays them on the display unit 13 as an index at the time of assembly (information presenting process) ). That is, since the connectors connected to the wires included in the three option subs a, c, e have a commonality, they are sorted into the same group. Then, the worker can recognize this information and perform work on the connection of the option sub, so that the labor of assembling the option sub can be significantly reduced. Specifically, as shown in FIG. 6, it is a task of preparing three option subs a, c and e connected in advance and assembling them to the base sub A, so that productivity can be improved. It becomes possible.

  Thus, in the wire harness production management device 100 according to the first embodiment, when the order information is input, the base sub and the plurality of option subs connected to the base sub are recognized based on the order information. Be done. Furthermore, it is determined whether or not each option sub is the same group, and the grouping information is displayed on the display unit 13. The worker can produce the wire harness in the procedure of connecting in advance the option subs determined to be in the same group, and then connecting to the base sub, so the productivity of the wire harness is remarkable. It is possible to improve.

  Also, by connecting three option subs a, c and e in advance, it is possible to prevent the connection terminal from being exposed. For example, in the case of option sub c, connection terminals TB-8 and TB-9 exist as shown in FIG. 4, and in option sub e, connection terminals TB-12 and TB as shown in FIG. There is -13. Therefore, when transporting to the production line where the flow operation is performed in this state, each connection terminal is transported in the bare state, which may cause problems of damage and detachment. On the other hand, in the present invention, since the three option subs a, c, and e are transported to the production line in a connected state in advance, it can be avoided as much as possible that the connection terminals are transported in the exposed state. The occurrence of problems such as damage to the connection terminals can be avoided.

Description of Second Embodiment
Next, a second embodiment of the present invention will be described. In the second embodiment, the case where the wire harness selected based on the order information is the base sub A and five optional subs a, c, e, x, y will be described. That is, as shown in FIG. 2B, a case where two optional subs x and y are added in addition to the optional subs a, c and e will be described. The apparatus configuration is the same as that shown in FIG.

  The option subs a, c, and e are the same as in the first embodiment described above, and the option subs a, c, and e are connected as shown in FIG. 6 described above. FIG. 8 is an explanatory view showing a connection state of the option subs x and y and a circuit list. As shown in the circuit list of FIG. 8, the option sub y includes two connectors HC8 and HC9 and five electric wires L21 to L25. The electric wires L21 to L25 are respectively wired to connect the connectors HC8 and HC9.

  Further, the option sub x includes two connectors HC10 and HC11 and four electric wires L26 to L29. Then, as shown in the circuit list, the electric wires L26 and L27 are wired so as to connect the connectors HC10 and HC11, respectively. Electric wires L28 and L29 are arranged to connect between the connector HC10 and the connector HC9 provided in the option sub y. Therefore, the connection terminal TB-28 is attached to the end of the electric wire L28, and the connection terminal TB-29 is attached to the end of the electric wire L29.

Next, the calculation procedure of grouping of each option sub by the control unit 12 will be described with reference to the flowchart shown in FIG.
First, in step S31 of FIG. 12, the harness selection unit 124 waits for an order by the input unit 11. When order information is input from the input unit 11, in step S32, the harness selection unit 124 reads base sub and option sub information from the input order information. At this time, the information on the optional sub is determined by the grade of the vehicle and the optional equipment.

  In step S33, the connection information recognition unit 125 reads the connection information of each option sub stored in the connection information storage unit 121. In this process, the circuit list for option subs a, c and e shown in FIGS. 3 to 5 is recognized, and the circuit list for option subs x and y shown in FIG. 8 is recognized.

  In step S34, the sorting operation unit 122 determines whether the connectors connected to the wires included in each of the option subs a, c, e, x, y have commonality and routing commonality. , If there is a commonality in connectors or routings, sort as the same group. In the present embodiment, as shown in FIG. 6, since the option subs a, c, and e have common connectors to which the respective electric wires are connected, the sorting operation unit 122 includes the option subs a, c, and e. Sort as the same group.

  Further, as shown in FIG. 8, since the option subs x and y have a common connector connected to each wire, the sorting operation unit 122 sorts the option subs x and y as the same group. . Therefore, as shown in FIG. 6, the connection terminal TB-12 attached to the electric wire L12 of the harness e is connected to the connector HC2 of the harness a, and the connection terminal TB-13 attached to the electric wire L13 of the harness e is the harness a Connected to the connector HC3. The connection terminal TB-8 attached to the electric wire L8 of the harness c is connected to the connector HC7 of the harness e, and the connection terminal TB-9 attached to the electric wire L9 of the harness c is connected to the connector HC3 of the harness a . As a result, the connection which precedes at four places becomes possible.

  On the other hand, as shown in FIG. 8, the connection terminal TB-28 attached to the electric wire L28 of the option sub x and the connection terminal TB-29 attached to the electric wire L29 are connected to the connector HC9 of the option sub y. As a result, the preceding connection can be made in two places. Here, there is no connection relation to a common connector between option subs a, c, e and option subs x, y. Therefore, the three option subs a, c and e are connected to form an integrated option sub. Furthermore, two optional subs x and y are connected to form an integrated optional sub.

  Then, by connecting three option subs a, c and e, an integrated option sub α as shown in FIG. 9 is formed, and by assembling two option subs x and y, as shown in FIG. An integrated optional sub-beta is formed.

  In step S35 in FIG. 12, the sorting operation unit 122 reads the route information of the integrated option sub α and β. Then, it is determined whether there is a wire passing through the common route. As shown in FIG. 11, when two integrated optional sub-alphas and betas pass in common in path P, it is possible to make the electric wire of this part common and combine two optional sub-alphas and betas It is. Therefore, in the path P, two option subs α and β are integrated to form an option sub. Then, the option sub combining α and β is connected to the base sub-A. By doing this, the operation of combining the base sub A and the option sub is performed only once, and the workability and productivity can be improved.

  In step S36, the sorting operation unit 122 sorts grouping information indicating that the three option subs a, c, and e are sorted into the same group, and the two options x and y are sorted into the same group, It is stored in the sorting data storage unit 123. By using this grouping information, when five option subs a, c, e, x, y are selected from the next time onward, it is possible that they belong to the same group without performing another sorting operation. It can be recognized.

  Thus, in the wire harness production management apparatus 100 according to the second embodiment, when order information is input, a plurality of option subs connected to the base sub and the base sub are recognized based on the order information. Ru. Further, it is determined whether each option sub is the same group. The operator forms option subs by connecting in advance option subs determined to be in the same group. Furthermore, it is determined whether or not there are multiple integrated option subs that pass through the same route, and these are combined if they pass through the same route. Then connect to the base sub. Therefore, since the plurality of optional subs connected to the base sub are connected at the earliest possible stage and connected to the base sub, the labor of the operator can be reduced and the productivity of the wire harness can be remarkably improved. .

Description of Third Embodiment
Next, a third embodiment of the present invention will be described. FIG. 13 is a block diagram showing the configuration of a production control device 101 for a wire harness according to the third embodiment. The production management apparatus 101 shown in FIG. 13 includes the input unit 11, the control unit 12a, and the display unit 13 as in the first embodiment described above. The third embodiment is different from the first embodiment in that the control unit 12a includes a working time determination unit 126.

  The working time determination unit 126 stores the required time of work for combining optional subs, and calculates the required time required for the combination based on the combination information set by the sorting calculation unit 122. For example, when combining option subs B, C, D, E, and F, the required time required for combining any two connectable option subs is calculated. Specifically, the required time required for each combination of option subs B and C, a combination of C and D, a combination of D and E, a combination of E and F, a combination of B and D, etc. is calculated. Alternatively, the required time previously input is stored.

  Furthermore, when the number of divisions (this is n) when combining option subs is input from the input unit 11, a plurality of option subs are combined into n groups. That is, an option sub of n division is formed. At this time, the time required for the combination is set to be substantially uniform for each set. For example, if the division number n is “2” and the time required for the combination of option subs B and C and C and D is substantially the same as the time required for the combination of option subs E and F, 3 Set one option sub B, C, D as one group and two option sub E, F as one group to set a group of two divisions. The reason for dividing the option sub of one group into n is to share the option sub among multiple workers and combine them.

The processing procedure of the production management device 101 according to the third embodiment will be described below with reference to the flowchart shown in FIG.
The processes of steps S51 to S54 shown in FIG. 14 are the same as the processes of S11 to S14 shown in FIG.

  When the plurality of option subs are classified into groups in the process of step S54, the working time determination unit 126 sets the division number n input from the input unit 11 in step S55. For example, when there are many optional subs in one group, this is divided into n groups.

  In step S56, the working time determination unit 126 calculates the working time required for the combination of optional subs in the same group (connection work). The working time is stored, for example, in a memory or the like (not shown). Alternatively, the operation time may be determined by calculation based on the connection location between the wire and the connector, the length of the wire, the degree of difficulty of the connection operation, and the like.

  In step S57, the working time determination unit 126 sets a group of n divisions so that the total working time becomes uniform. For example, as described above, three option subs B, C, and D are set as one group, and two option subs E, F are set as one group, and a group of two divisions is set.

  In step S58, the grouping information and each set of information are stored in a memory or the like. Furthermore, each grouping information and information on gathering are displayed on the display unit 13.

  Thus, in the production management apparatus 101 according to the third embodiment, when there are a large number of option subs in the same group, the group is further divided into n groups. At this time, the work time required for the combination is set to be uniform for each set. Then, since each grouping information and each group information is displayed on the display unit 13, it is possible to make the operator recognize the grouping of each grouped option sub. As a result, since it is possible to carry out the combination work in substantially the same time for each group, when a plurality of workers share and carry out the work of the optional sub combination, the work efficiency is improved. It becomes possible.

Description of the Fourth Embodiment
Next, a fourth embodiment of the present invention will be described. FIG. 15 is a block diagram showing the configuration of a production control device 102 for a wire harness according to the fourth embodiment. The production management apparatus 102 illustrated in FIG. 15 includes the input unit 11, the control unit 12b, and the display unit 13 as in the first embodiment described above. The fourth embodiment is different from the first embodiment in that the control unit 12 b includes a circuit number determination unit 127.

  The circuit number determination unit 127 stores the number of circuits of each option sub (the number of connectors and the number of electric wires), and calculates the number of circuits based on the combination information set by the sorting calculation unit 122. For example, when option subs B, C, D, E, and F exist in the same group, the number of circuits of each of the option subs B, C, D, E, and F is calculated.

  Furthermore, when the number of divisions (this is n) when combining option subs is input from the input unit 11, a plurality of option subs are combined into n groups. That is, an option sub of n division is formed. At this time, the number of circuits is set to be substantially uniform for each set. For example, when the division number n is “2” and the number of circuits of the option sub B and C and the number of circuits of the option sub D, E, F are substantially the same, two option sub B , C as one group, three option sub D, E, F as one group, set a group of 2 division.

  The processing procedure of the production management device 102 according to the fourth embodiment will be described below with reference to the flowchart shown in FIG.

  The processes of steps S71 to S74 shown in FIG. 14 are the same as the processes of S11 to S14 shown in FIG.

  When the plurality of option subs are classified into groups in the process of step S74, the circuit number determination unit 127 sets the division number n input from the input unit 11 in step S75. For example, when there are many optional subs in one group, this is divided into n groups.

  In step S76, the circuit number determination unit 127 calculates the number of optional sub circuits in the same group. The number of circuits is stored, for example, in a memory or the like (not shown).

  In step S77, the circuit number determination unit 127 sets a group of n divisions so that the total number of circuits is uniform. For example, as described above, two option subs B and C are set as one group, and three option subs D, E, F as one group, and a group of two divisions is set.

  In step S78, the grouping information and each set of information are stored in a memory or the like. Further, grouping information and information of each group are displayed on the display unit 13.

  Thus, in the production management apparatus 102 according to the fourth embodiment, when there are many option subs in the same group, the group is further divided into n groups. At this time, the number of circuits is set to be uniform for each set. Then, since each grouping information and each group information is displayed on the display unit 13, it is possible to make the operator recognize the grouping of each grouped option sub. As a result, it is possible to carry out the combination work at almost the same time for each group. That is, if the number of circuits is approximately the same, it can be expected that the time required for the connection work of the connector and the electric wire is substantially the same, so that the work efficiency can be improved.

Description of Fifth Embodiment
Next, a fifth embodiment of the present invention will be described. FIG. 17 is a block diagram showing the configuration of a production control device 103 for a wire harness according to the fifth embodiment. The production management apparatus 103 shown in FIG. 17 includes an input unit 11, a control unit 12c, and a display unit 13, as in the first embodiment described above. The fifth embodiment is different from the first embodiment in that the control unit 12 c includes a harness amount determination unit 128.

  The harness amount determination unit 128 stores the amount of harness (total length or weight of electric wires) of each optional sub, and calculates the amount of harness based on the combination information set by the sorting calculation unit 122. For example, when option subs B, C, D, E, and F exist in the same group, the harness amount of each of the option subs B, C, D, E, and F is calculated.

  Furthermore, when the number of divisions (this is n) when combining option subs is input from the input unit 11, a plurality of option subs are combined into n groups. That is, an option sub of n division is formed. At this time, the amount of harness is set to be substantially uniform for each set. For example, when the division number n is “2” and the total harness amount of option subs B and C and the total harness amount of option subs D, E, F are substantially the same, two option sub B , C as one group, three option sub D, E, F as one group, set a group of 2 division.

  The processing procedure of the production management device 103 according to the fifth embodiment will be described below with reference to the flowchart shown in FIG.

  The processes of steps S91 to S94 shown in FIG. 18 are the same as the processes of S11 to S14 shown in FIG.

  When the plurality of option subs are classified into groups in the process of step S94, the harness amount determination unit 128 sets the division number n input from the input unit 11 in step S95. For example, when there are many optional subs in one group, this is divided into n groups.

  In step S96, the harness amount determination unit 128 calculates the amount of optional sub-harnesses in the same group. The harness amount is stored, for example, in a memory or the like (not shown).

  In step S97, the harness amount determination unit 128 sets a group of n divisions so that the total amount of harnesses becomes uniform. As described above, two option subs B and C are set as one group, and three option subs D, E, F as one group, and a group of two divisions is set.

  In step S98, each set of information is stored in a memory or the like. Further, the information on the collection is displayed on the display unit 13.

  As described above, in the production management apparatus 103 according to the fifth embodiment, when there are many option subs in the same group, the group is further divided into n groups. At this time, the amount of harness is set to be uniform for each set. Then, since each grouping information and each group information is displayed on the display unit 13, it is possible to make the operator recognize the grouping of each grouped option sub. As a result, it is possible to carry out the combination work at almost the same time for each group. That is, if the amount of harness is substantially the same, it can be expected that the time required for the connection work of the connector and the wire will be substantially the same, so that the work efficiency can be improved.

  As mentioned above, although the production control apparatus of the wire harness of this invention and the production control method of the wire harness were demonstrated based on embodiment of illustration, this invention is not limited to this, The structure of each part has the same function.
