A. Embodiment 1 FIG. System Configuration FIG. 1 is a diagram showing a schematic configuration of a work procedure guidance system 10 (hereinafter also referred to as “guidance system 10”) according to an embodiment of the present invention. The guidance system 10 in this embodiment guides the work procedure of vehicle maintenance to an operator, and is installed, for example, in a vehicle maintenance factory. The guidance system 10 includes an input unit 12, a storage unit 14, a control unit 16, a work database 18 (hereinafter referred to as “work DB 18”), and a monitor 20.

  The input unit 12 includes a keyboard 22 and a mouse 24, and in accordance with the operation of the operator, a target maintenance operation (hereinafter also referred to as “target operation Ot”) and a part (hereinafter “the target operation Ot”). It is also possible to input “target part Pt”. In the present embodiment, the target operation Ot is a replacement operation, but inspection, adjustment, processing, removal (without replacement), attachment (without removal), or removal (without attachment) of parts. Can be set as the target operation Ot. Moreover, in this embodiment, it is comprised so that the target operation | work Ot may be input directly, and in the following description, description is expanded by the form which inputs the target operation | work Ot directly instead of the target component Pt.

  The storage unit 14 includes, for example, a non-volatile memory and a volatile memory, and stores a program (work procedure guide program) for guiding a work procedure for maintenance. The control unit 16 includes, for example, a central processing unit (CPU), and performs a work procedure {that is, a target work Ot and a work necessary for the target work Ot (hereinafter also referred to as “related work Or”)}. Guide the person. Specifically, the control unit 16 causes the monitor 20 to display a description of the related work Or and the target work Ot. The work DB 18 stores data necessary for the control unit 16 to guide work procedures.

2. Outline of Function Next, the function of the guidance system 10 will be briefly described, including a system operation procedure, as an example of the work of attaching and detaching the door portion of the vehicle.

  FIG. 2 shows a screen 30 as an example of a screen displayed on the monitor 20. As shown in FIG. 2, the screen 30 includes a LON input field 32, a target part name input field 34, and a tree diagram 36.

  The LON input field 32 is a field for inputting a work number (hereinafter referred to as “LON” (Labor Operation Number)), and the target part name input field 34 is a field for inputting the name of the target part Pt ( The method of use will be described later.)

  The dendrogram 36 shows the order of attaching and detaching each part. “14TEST01” on the most upstream side (left side in FIG. 2) of the tree diagram 36 is a number (model number) assigned to each model. Each row (for example, “COVER, DOOR GRIP LEFT FRONT -0.1-8431A5”) displayed on the downstream side of the model number “14TEST01” is information of the target work Ot certified for each part.

  FIG. 3 shows an example of information on the target work Ot of each part corresponding to the tree diagram 36. As shown in FIG. 3, the information of each target work Ot includes model number, LON, standard work man-hour (hereinafter referred to as “FRT” (Flat Rate Time)), work classification, part name, It has a work explanation text explaining the contents of the detachment work in the work section, and a work explanation image showing the detachment state of the parts including the balance with the peripheral parts for easy viewing.

  The LON is allocated for each part removal operation. The FRT is a standard man-hour for removing and replacing parts. The work classification indicates desorption (R & I), inspection, adjustment, processing, installation, removal, and the like.

  All the work actually performed is registered in advance. At that time, even if it is the same part, the work is different. For example, the work is removed from the front of the target part Pt and the back of the target part Pt. If the removal time of the target part Pt is different from the case where it is removed, or if the removal time of the target part Pt is different between the state where the entire unit is removed from the vehicle body and the state where the unit is attached, the same LON Add a branch number afterwards (add a hyphen and mark it as “XXX-X”), and mark that the same part is being removed but the work is different.

  Note that a dedicated addition man-hour, a shared addition man-hour, and an immediately preceding work number (hereinafter referred to as “immediately preceding LON”) described later are omitted here.

  As can be seen from FIG. 2, the tree diagram 36 shows the order in which the parts are removed (and the order in which they are attached thereafter). That is, in order to replace the door latch (front left) (LATCH FRONT INSIDE LEFT), it is necessary to remove the door glass sash (front left) (SASH, FRONT DOOR GLASS LEFT), and to remove the door glass sash. Before that, it is necessary to remove the inside handle (front left) (HANDLE, FRONT INSIDE LEFT). To remove the inside handle, it is necessary to remove the door lining (front left) (LINING, FRONT DOOR LEFT) before that. In order to remove the door lining, it is necessary to remove the door grip cover (front left) (COVER, DOOR GRIP LEFT FRONT) before that. Here, the removal of the door grip cover is the most upstream operation. In the following and FIGS. 3 to 9, “(left front)” is omitted.

  For example, when a door latch is selected as the target part Pt (when the cursor 24 is aligned with the row of the sixth door latch in the dendrogram 36 in FIG. 2 and the execution is performed after the mouse 24 is selected). ) The guidance system 10 searches for all work routes including registered branch numbers up to LON = 7481A5, and determines the route (work procedure) that minimizes the total man-hours. Then, as shown in FIG. 4, it is determined that the door grip cover removal, the door lining removal, the inside handle removal, and the door glass sash removal are required as the attachment / detachment procedure for replacing the door latch. Alternatively, the procedure after the door latch replacement, that is, the installation of the door glass sash, the installation of the inside handle, the installation of the door lining, and the installation of the door grip cover are also judged.

  Then, the guidance system 10 guides each detachment work as the related work Or and the target work Ot based on the determination result (here, by guiding the door latch detachment work, Guides you to replace the door latch.)

  As shown in FIG. 5, on the monitor 20 of the guidance system 10, an image and text for explaining the work for each detachment work are displayed in the order of the work. In FIG. 5, all the detachment work is displayed by scrolling the screen, but the screen may be switched for each part by operating the mouse 24.

  Also, when a door outer handle is selected as the target part Pt (the cursor 24 is aligned with the row of the eighth door outer handle in the dendrogram 36 in FIG. The guidance system 10 searches for all work routes including registered branch numbers up to LON = 818110, and determines the route with the minimum total man-hour. Then, as shown in FIG. 6, it is determined that the door grip cover must be removed, the door lining removed, and the plastic cover removed as the attachment / detachment procedure for exchanging the door outer handle. Then, as shown in FIG. 7, the guidance system 10 guides each detaching work as the related work Or and the target work Ot based on the determination result (here, guiding the detaching work of the door outer handle). (The guide guides the replacement of the door outer handle.)

  In the above description, the case where the door latch is selected as an individual part (FIGS. 4 and 5) and the case where the door outer handle is selected (FIGS. 6 and 7) have been described. However, in the guidance system 10, a plurality of parts are selected simultaneously. You can also.

  For example, when a door latch and a door outer handle are selected as the target part Pt (for example, after selecting the line by moving the cursor to the door latch line with the mouse 24 and selecting the line by moving the cursor to the outer handle line) When the execution is performed), the guidance system 10 guides a procedure for attaching and detaching the door latch and the door outer handle with the minimum standard man-hour of one operation. Specifically, as shown in FIG. 8, it is determined that it is necessary to remove the door grip cover, remove the door lining, remove the inside handle, and remove the door glass sash as an attachment / detachment procedure for exchanging the door latch. Further, it is determined that it is necessary to remove the door grip cover, remove the door lining, and remove the plastic cover as an attachment / detachment procedure for exchanging the door outer handle. In addition, by calculating the detaching procedure that minimizes the total man-hour of a series of operations, it is determined that there is a door grip cover removal and a door lining removal as overlapping related operations Or, as shown in FIG. As shown, the detaching operation with the minimum man-hour that can be performed in a series of work procedures is determined.

  Based on the determination result, the guidance system 10 guides each detachment work as the related work Or and the target work Ot as shown in FIG.

3. More Detailed Configuration of Work DB 18 FIG. 10 is modeled for easy understanding of an example of the detailed structure of data stored in the work DB 18. As shown in FIG. 10, the work DB 18 includes model number data, LON (work number) data, FRT (standard work man-hour) data, dedicated addition man-hour data, shared addition man-hour data, It has work number data (hereinafter referred to as “immediately preceding LON”), part name data, and work description data.

  LON is a number assigned for each part removal operation. In the present embodiment, equivalent LONs are distinguished by adding hyphens and numbers as branching operations as described above (for example, 3, 3-1, 3-2). Here, the equivalent LON means that the same part is attached / detached, but the attaching / detaching procedure, FRT, dedicated addition man-hour or shared addition man-hour is different. For example, even if it is the same part, there is a case where the other part is removed from the front of the vehicle and the part is reached and a case where the other part is removed from the rear of the vehicle and the part is reached Equivalent LONs are used. Also, there are cases where both the case where the entire unit with a certain part attached is removed from the vehicle body and the part is removed, and the case where the whole unit is attached to the body and only the parts related to the part are removed in order, An equivalent LON is used.

  The FRT is a standard man-hour for removing and replacing parts. As described above, since the detachment of parts includes both the removal before the target operation Ot and the attachment after the target operation Ot, the FRT is a standard man-hour for the removal before the target operation Ot and the standard of the attachment after the target operation Ot. It is a combination of man-hours. However, when there is a target work Ot that requires only one of removal before the target work Ot and attachment after the target work Ot, the standard man-hours of both can be divided and only one of them can be used.

  The dedicated addition man-hours and the shared addition man-hours are a kind of addition man-hours. The additional man-hour is a standard man-hour required for ancillary work such as inspection and adjustment associated with component removal and replacement itself.

  The dedicated additional man-hour is a standard man-hour for ancillary work that occurs only when a specific part is replaced. Dedicated addition man-hours do not occur just by attaching / detaching the specific part (the act of attaching the removed part as it is without replacement), that is, by attaching / detaching as a step in the middle for attaching / detaching other parts. As an exchanging operation for generating the dedicated addition man-hour, for example, there is a replacement of the alternator belt, and the man-hour required for the inspection of the alternator belt required for the replacement of the alternator belt is the dedicated addition man-hour.

  The common additional man-hour is a standard man-hour for ancillary work required for each of the detaching work of a plurality of specific parts. Even if one of the specific parts is removed or attached, it is necessary to remove the specific part in the middle of the work process (that is, if the removal of the specific part is the related work Or). Will occur. However, when there are a plurality of shared addition man-hours of the same target in the selected work route, only one is added and the others are treated as “0”.

  Examples of the common work include adjustment of a clutch switch and replenishment of automatic transmission fluid (AT fluid). Examples of components that require adjustment of the clutch switch in association with attachment / detachment include a clutch pedal, a multi-plate clutch, and the clutch switch itself. In addition, examples of components that need to be replenished with AT fluid as they are attached and detached include a torque converter, or a turbine, a stator, and a pump provided therein. Note that, as will be described later, the shared addition man-hour may change depending on which specific part is attached or detached.

  The immediately preceding LON is a LON of a component (immediately preceding component) to be removed immediately before each operation. By using the immediately preceding LON, as shown in FIG. 11, each LON is associated with a tree structure. As a result, it is possible to perform display as shown in the tree diagram 36 of FIG.

  10 and 11, for example, LON3 (removal of part C) needs to be performed immediately before LON4 (removal of part D), and LON2 (part B) immediately before LON3 (removal of part C). It is necessary to perform LON1 (removal of part A) immediately before LON2 (removal of part B).

  As described above, all work actually performed is performed by the creator (data input person) of the work DB 18 including the relationship with the immediately preceding LON. In other words, in FIG. 11, the left part indicates the entire upstream side (parts to be removed earlier), and the right part indicates the downstream side (parts to be removed later). Therefore, in the example of FIG. 11, LON1 (part A) and LON11 (part K) are parts that are first removed. In FIG. 11, in the parentheses on the right side of each LON, the part name, FRT, and shared addition man-hour (if present) or dedicated addition man-hour (if present) are shown from the left.

  The part name indicates the name of a part to be removed or replaced in the work. For example, if the part name is an engine, the part name indicates removal or replacement of the engine.

  The description of the work includes a work explanation text and a work explanation image as shown in FIG. For example, if the door panel is to be removed (removed), characters and images for explaining work procedures such as removing the inner handle fixing screw, removing the power window switch connector, and removing the screw from the grip base are included. In FIG. 10, the description of specific contents of the work description data and the work classification (see FIG. 3) are omitted.

4). Processing Performed by Work Procedure Guidance System Next, processing performed by the work procedure guidance system 10 of the present embodiment will be described. The processing described below is implemented by the control unit 16 executing the work procedure guidance program stored in the storage unit 14.

  FIG. 12 shows a flowchart of an outline of processing performed by the guidance system 10 of the present embodiment.

  In step S1, the target operation Ot (LON) of the target component Pt is selected. That is, in the state where the work procedure guidance program is activated, the control unit 16 causes the monitor 20 to display a screen such as the screen 30 of FIG. In the upper part of the screen 30, an LON input field 32 for inputting LON and a target part name input field 34 for inputting the name of the target part Pt are displayed. After the LON of the target work Ot is input to the LON input field 32, when the execution is performed with a click of an execution button (not shown) on the screen, the LON and various information corresponding thereto are displayed at the center of the screen. When the name of the target part Pt is input to the target part name input field 34 and executed, the target part Pt and various information corresponding thereto are displayed in the center of the screen. In addition, when the input name does not exist in the work DB, information about a component closest to the input name is displayed. The screen can be scrolled up and down.

  Various information displayed in the center of the screen includes model number, part name, FRT, shared addition man-hour (if any), dedicated addition man-hour (if any), and LON, which are displayed as a tree diagram ( (See FIG. 2). Note that information about each component on the downstream side is not displayed on the initial screen, but may be displayed by clicking the left button of the mouse 24 with the cursor positioned on the display of each component on the upstream side. . In this state, the worker uses the input unit 12 to select the target work Ot of the target part Pt. For example, the mouse 24 is operated to move the cursor to the line of the target work Ot and select the line. In the present embodiment, a plurality of target operations Ot can be input by repeating the above method. If the left button of the mouse 24 is double-clicked in the state where the input of the target work Ot is completed, a message asking the end of the selection and an OK button are displayed. If the OK button is pressed, the process proceeds to step S2 and work guidance is executed. .

  In step S <b> 2, the control unit 16 confirms work equivalent to the target work Ot selected in step S <b> 1 (hereinafter, collectively referred to as target work Ot), and is necessary along with the target work Ot. Confirm all combinations of related work Or. For example, in the example of FIG. 11, when the detaching operation (LON3) of the part C is selected, all the LONs of other detaching operations (that is, operations with branch numbers) of the same part C are selected. Next, based on all the selected LONs, all combination procedures that lead to these LONs are created. In the present embodiment, two combinations are created, and the first combination is a combination having LON3 as the target work Ot and LON1 and LON2 as the related work Or. The second combination is a combination having LON 3-1 as the target work Ot and LON 1 and LON 7 as the related work Or.

  When a plurality of target tasks Ot are selected in step S1, the control unit 16 confirms all the combinations of the related tasks Or and the target tasks Ot that are necessary for each target task Ot. For example, in the example of FIG. 11, when LON3 and LON10 are selected, LON3 is equivalent to LON3-1, and LON10 is equivalent to LON10-1. Therefore, the control unit 16 determines that there are the following four combinations as the combinations of the target work Ot and the related work Or.

  That is, the first combination is a combination including LON3 and LON10 as the target work Ot and LON1, LON2 and LON9 as the related work Or. The second combination is a combination having LON 3-1 and LON 10 as the target work Ot and LON 1, LON 7 and LON 9 as the related work Or. The third combination is a combination having LON3 and LON10-1 as the target work Ot and LON1, LON2, LON11 and LON12 as the related work Or. The fourth combination is a combination having LON 3-1 and LON 10-1 as the target work Ot and LON 1, LON 7, LON 11 and LON 12 as the related work Or.

  In step S3 of FIG. 12, the control unit 16 determines whether there are a plurality of combinations of the target work Ot and the related work Or confirmed in step S2. When there are a plurality of combinations of the target work Ot and the related work Or (S3: YES), the process proceeds to step S4. When there are not a plurality of combinations of the target work Ot and the related work Or (S3: NO), the process proceeds to step S5.

  In step S4, the control unit 16 selects an optimal combination from a plurality of combinations of the target work Ot and the related work Or. Here, the “optimal combination” refers to a combination that satisfies a predetermined condition such that the total man-hour MHtotal [minute], which will be described later, is minimum.

  FIG. 13 and FIG. 14 show a flowchart (S4 in FIG. 12) for selecting an optimum combination from among a plurality of combinations of the target work Ot and the related work Or. After selecting one of the plurality of combinations, in step S11, the control unit 16 determines a shared addition man-hour. More specifically, a search is performed for LONs of the target work Ot and the related work Or included in the selected combination of the target work Ot and the related work Or that have a shared addition man-hour. Then, when there are a plurality of LONs having a shared addition man-hour, it is determined whether or not each LON targets an equivalent part. Whether or not each LON is targeted for an equivalent part can be determined, for example, by attaching an identifier of a shared addition man-hour to each LON.

  When a plurality of LONs having a shared addition man-hour are targeted for an equivalent part, the largest common addition man-hour is valid, and the other common addition man-hours are set to zero [minutes]. When there are a plurality of LONs having the largest shared addition man-hours, one arbitrarily selected by the control unit 16 is valid, and the others are zero [minutes]. For example, in the example of FIGS. 10 and 11, the shared addition man-hour for LON2 is 5 [minutes], and the shared add-on manhour for LON3 and LON4 is 10 [minutes]. Therefore, the control unit 16 validates one common addition man-hour of LON3 and LON4, and sets the other of LON3 and LON4 and the common addition man-hour of LON2 to zero. Actually, the number of shared addition man-hours is often the same. When there are a plurality of common addition man-hours, in most cases, only one is added and then treated as “0”.

  In step S12 of FIG. 13, the control unit 16 determines whether or not the related work Or equivalent to the target work Ot exists in the combination of the selected target work Ot and the related work Or.

  When the related work Or equivalent to the target work Ot does not exist in the combination (S12: NO), the process proceeds to step S14. When the related work Or equivalent to the target work Ot exists in the combination (S12: YES), the FRT of the target work Ot is prioritized over the related work Or in step S13. In other words, the control unit 16 validates the FRT of the target work Ot and sets the FRT of the related work Or to zero [minutes]. Here, “validate FRT” means that the value of FRT (FIG. 10) is added to the total man-hour MHtotal as it is in step S19 described later.

  In step S <b> 14, the control unit 16 determines whether there are a plurality of related tasks Or that are equivalent to each other and that are not equivalent to the target task Ot in the combination of the selected target task Ot and the related task Or. . When a plurality of related work Or does not exist in the combination (S14: NO), the process proceeds to step S18. If there are a plurality of related tasks Or in the combination (S14: YES), the process proceeds to step S15. For example, in the example of FIGS. 10 and 11, when LON4 and LON8 are selected as the target work Ot, there are LON3 and LON3-1 that are equivalent to each other as the related work Or. In this case, step S14 is YES.

  In step S15, the control unit 16 determines whether or not there are a plurality of related tasks Or having the smallest FRT among the related tasks Or that are equivalent to each other and are not equivalent to the target task Ot. When there are a plurality of the related work Or (S15: YES), in step S16, the control unit 16 validates the FRT of the related work Or on the upstream side and sets the FRT of the other related work Or to zero [minutes]. . When there are not a plurality of related works Or (S15: NO), in step S17, the control unit 16 validates the FRT of the related work Or with the smallest FRT, and sets the FRTs of the other related works Or to zero [minutes]. To do. For example, in the example of FIGS. 10 and 11, when LON4 and LON8 are selected as the target work Ot, there are equivalent LON3 and LON3-1 as the related work Or, and the FRT of LON3 is 10 [minutes]. On the other hand, the FRT of LON3-1 is 5 [minutes]. In this case, since the FRTs of LON3 and LON3-1 are different, step S15 is NO. In step S17, the FRT of LON3-1 is validated and the FRT of LON3 is set to zero [minutes].

  In step S18, the control unit 16 determines the dedicated addition man-hour. Specifically, the LON of the related work Or included in the selected combination of the target work Ot and the related work Or is searched for one having a dedicated additional man-hour. Then, the dedicated additional man-hour corresponding to the LON of the related work Or is set to zero [minutes]. The dedicated addition man-hour corresponding to the LON of the target work Ot is valid as it is.

  In step S19, the control unit 16 calculates the total man-hour MHtotal using the results of steps S11 to S18. The total man-hour MHtotal is the sum of the FRT, the shared addition man-hour (valid) and the dedicated addition man-hour (valid).

  In step S20, the control unit 16 determines whether the total man-hour MHtotal has been calculated for all combinations of the target work Ot and the related work Or. If there is a combination for which the total man-hour MHtotal has not been calculated (S20: NO), the process returns to step S11, and the total man-hour MHtotal is calculated for one of the combinations for which the total man-hour MHtotal has not been calculated. When the total man-hour MHtotal is calculated for all the combinations (S20: YES), the process proceeds to step S21 in FIG.

  In step S21 of FIG. 14, the control unit 16 determines whether or not the combination of the target work Ot and the related work Or has the smallest total man-hour MHtotal. When there is one such combination (S21: YES), in step S22, the control unit 16 selects the combination as the optimal combination. When there are a plurality of combinations having the minimum total man-hour MHtotal (S21: NO), in step S23, it is determined whether or not there is a combination including more worker priority LONs than others. The worker priority LON is an LON actually selected by the worker using the mouse 24. For example, when the worker selects the LON 3-1 as the target work Ot, the LON 3-1 is the worker priority LON, and the LON 3 equivalent to the LON 3-1 is not the worker priority LON.

  When there is a combination including more worker priority LONs than others (S23: YES), the process proceeds to step S24, and when the combination does not exist (that is, when all combinations have the same number of worker priority LONs). (S23: NO), it progresses to step S26.

  In step S24, the control unit 16 determines whether or not an optimal combination can be selected from a plurality of combinations that minimize the total man-hour MHtotal based on the worker priority LON. The determination is performed as follows, for example. That is, it is determined whether or not only one of the plurality of combinations that minimizes the total man-hour MHtotal includes the worker priority LON. When there is one such combination, the combination can be selected as the optimal combination. In addition, when there are a plurality of combinations having the largest worker priority LON among a plurality of combinations having the minimum total man-hour MHtotal, there is one combination including the LON having the smallest branch number among the worker priority LONs. (No branch number is treated as if the branch number is 0). When there is one such combination, the combination can be selected as the optimal combination. Further, when there are a plurality of combinations including the LON having the smallest branch number among the worker priority LONs, the combination including the largest number of worker priority LONs positioned highest in the display screen of the monitor 20 (for example, FIG. 2). It is determined whether or not there is one. When there is one such combination, the combination can be selected as the optimal combination.

  When the optimal combination can be selected based on the worker priority LON (S24: YES), in step S25, the control unit 16 selects the optimal combination according to the worker priority LON. If the optimum combination cannot be selected based on the worker priority LON (S24: NO), the process proceeds to step S26.

  In step S26, based on the system priority work number (hereinafter referred to as “system priority LON”), the control unit 16 can select an optimal combination from a plurality of combinations that minimize the total man-hour MHtotal. Determine. The system priority LON is stored in advance in the storage unit 14 as an LON used preferentially by the guidance system 10. The determination in step S26 can be performed in the same manner as in step S24 after replacing the operator priority LON with the system priority LON.

  When the optimal combination can be selected based on the system priority LON (S26: YES), in step S27, the control unit 16 selects the optimal combination according to the system priority LON. When the optimal combination cannot be selected based on the system priority LON (S26: NO), in step S28, the control unit 16 sets an arbitrary combination as the optimal combination from a plurality of combinations that minimize the total man-hour MHtotal. select.

  Returning to FIG. 12, in step S5, the control unit 16 performs work guidance using the combination of the target work Ot and the related work Or identified in steps S2 to S4. That is, when there is one combination of the target work Ot and the related work Or (S3: NO), work guidance is performed using the combination. For example, when the target work Ot is LON5 and LON7, part A (removal) → B (removal) → E (removal) → G (removal) → G (adjustment of replacement parts / dedicated addition man-hours, mounting) → E ( The target work Ot (parts E and G) and the related work Or (parts A and B) are guided in the order of attachment of replacement parts) → B (attachment) → A (attachment).

  If there are a plurality of combinations of the target work Ot and the related work Or (S3: YES), work guidance is performed using the optimum combination selected in step S4. For example, when the target work Ot is LON3 and LON7, there are the following two combinations of the target work Ot and the related work Or. The first combination is a combination having LON3 and LON7 as the target work Ot and LON1 and LON2 as the related work Or. The second combination is a combination having LON 3-1 and LON 7 as the target work Ot and only LON 1 as the related work Or.

  The total man-hour MHtotal of the first combination is 50 [minutes] (= FRT10 [minutes] of LON1 + FRT10 [minutes] of LON2 + FRT10 [minutes] of LON3 + 10 [minutes] of shared addition of LON3 + FRT5 [minutes] of LON7 + LON7 Dedicated additional man-hours 5 [minutes]). The total man-hour MHtotal of the second combination is 25 [minutes] (= FRT10 [minutes] of LON1 + FRT5 [minutes] of LON7 + dedicated additional manhours of LON7 + FRT5 [minutes] of LON3-1). Accordingly, the total man-hour MHtotal of the second combination is smaller than that of the first combination. In this case, use the second combination as the optimal combination, parts A (removal) → G (removal) → C (removal) → C (replacement part installation) → G (replacement part adjustment / dedicated additional man-hours, installation ) → A (attachment) in order of the target work Ot (LON3, LON7) and related work Or (LON1).

  As the work guidance, for example, the items of the related work Or and the target work Ot are displayed in the order of the work on the left side of the screen of the monitor 20, and the detailed explanation of each related work Or and the target work Ot is scroll-displayed together with images on the other screens. be able to. Alternatively, the detailed description can be displayed by switching the screen for each of the related work Or and the target work Ot. In either case, the total of FRTs up to each work and the total man-hour actually taken for each work are displayed. Further, the control unit 16 calculates a wage based on the total man-hour MHtotal and outputs it together with the total man-hour MHtotal.

5. As described above, according to the present embodiment, the combination of the work explanation data set in advance for each attachment / detachment procedure is not sequentially displayed, but in accordance with the selected attachment / detachment procedure. The work explanation data can be rearranged and displayed for each work. For this reason, even when there are a plurality of detachment procedures, it is not necessary to prepare a plurality of combinations of work commentary data, and it is possible to rearrange and display each time according to the selection, and high versatility can be obtained. .

  In the present embodiment, the control unit 16 selects a desorption procedure that minimizes the total man-hour MHtotal until the designated target operation Ot (removal or replacement of the target component Pt), and describes the work along the desorption procedure. Display data. Thereby, each work commentary data can be rearranged and displayed along the attachment / detachment procedure in which the total man-hour MHtotal is minimized. Therefore, the worker can perform efficient work without depending on experience and skill.

  In the present embodiment, when a plurality of target operations Ot are designated via the input unit 12, the control unit 16 minimizes the total man-hour MHtotal until reaching the plurality of target operations Ot among all combinations of the detachment procedures. The work explanation data is displayed along the desorption procedure. Thereby, even when a plurality of target tasks Ot are designated, it is possible to perform efficient tasks. In particular, in the case of a device such as a vehicle in which the number of parts included in the device is enormous, the effect is great.

  In the present embodiment, when a plurality of target tasks Ot are selected via the input unit 12, the control unit 16 determines the related task Or between the plurality of target tasks Ot using the immediately preceding LON, and the determined relationship A plurality of target tasks Ot are guided using the task Or. According to the present embodiment, it is possible to trace from each target work Ot to the first related work Or using the immediately preceding LON. As a result, it is possible to specify the related work Or and perform guidance to the target work Ot using the specified related work Or. Thereby, when a plurality of target tasks Ot are selected, guidance without overlapping related tasks Or can be performed, and guidance to each target task Ot can be efficiently performed.

However, the target component Pt is directly input by associating each component with the operation as data. You may do it. Moreover, although the guidance system 10 was installed in the vehicle maintenance factory, the present invention is not limited to this, and may be installed in other places such as a vehicle store or a vehicle maintenance educational institution. Furthermore, it may be configured as a network that collects data in a server, acquires the data from each terminal, and uses it for operation.

  In the above embodiment, the guidance of the target work Ot and the related work Or is displayed on the monitor 20, but the present invention is not limited to this, and sound may be output from a speaker.

  In the above-described embodiment, the control unit 16 selects the detachment procedure that minimizes the total man-hour MHtotal until the designated target operation Ot (removal of the target component Pt). In other words, the desorption procedure is selected based on the rule that selects the desorption procedure that minimizes the total man-hour MHtotal until the designated target operation Ot, but the desorption procedure may be selected based on another rule. it can. For example, the attachment / detachment procedure can be selected based on a rule of selecting an attachment / detachment procedure configured by an operation manually selected by the operator. In this case, the work commentary data can be rearranged and displayed as if it were handmade.

  In the above embodiment, the target work Ot and the related work Or are only removed or replaced, but other work (for example, inspection, adjustment, processing, attachment (without removal) of parts, or removal (with attachment) May be included in the target work Ot and the related work Or. In this case, for example, when a part (target work Ot) in the tree diagram displayed on the monitor 20 is double-clicked with the mouse 24, the work content {part replacement, inspection, adjustment, processing, detachment (without replacement) 1), attachment (without removal), and removal (without attachment)} are displayed, and the work content can be selected using the keyboard 22 or mouse 24. be able to. Further, the FRT, shared addition man-hour, and dedicated addition man-hour for each work content may be stored in the work DB 18 in advance.

  In the above-described embodiment, both the removal of the related part Pr before the target work Ot and the attachment of the related part Pr after the target work Ot are guided as the related work Or, but only the removal of the related part Pr before the target work Ot is guided. You may guide. Similarly, in the above-described embodiment, as the FRT of the related work Or, the common addition man-hour and the dedicated addition man-hour, both the man-hours for removing the related parts Pr before the target work Ot and the man-hours for mounting the related parts Pr after the target work Ot are used. However, only the man-hours for removing the related parts Pr before the target work Ot may be considered.

  In the above embodiment, the total man-hour MHtotal having the combination of the target part Pt and the related part Pr as a unit is used as a criterion. However, a combination of only the related part Pr may be used as a unit.
