Description

  The present invention relates to a production management apparatus, a production management program, and a production management method, and particularly records a production management apparatus, a production management program, and a production management program that can suitably perform production management of a single product. The present invention relates to a computer-readable recording medium and a production management method.

  Large one-piece products still occupy an important part in Japanese industry. Conventionally, these single-product products are relatively expensive, so the cost awareness is low, and the period from order receipt to completion is generally long. However, as competition between companies intensifies in recent years, it has become necessary to complete in a shorter period. In addition, it is necessary to reduce costs in response to the decline in selling prices.

  In order to complete the product in a short time, it may be possible to place an order for parts, materials, etc. with a long delivery date when the basic design is completed. However, after the prior ordering, the customer's intention may change later, and the original specification may be changed. In addition, the parts ordered in advance may not always be manufactured as designed, and as a result of changing the parts so that they can be manufactured, the design of the related parts may have to be changed. In addition, the initial design may be poor and must be corrected after prior arrangement.

  In this case, for example, when 100 parts are arranged in advance with a product composed of 1000 parts, if several parts are changed, it is possible to deal with them by manpower. However, as the number of cases increases, it becomes very difficult to deal with them manually. As a result, it has a significant impact on the delivery date, quality and cost of the product. In particular, the cost is important. When the customer's intention changes, it is necessary to quickly and accurately grasp the changed parts, the parts that are no longer needed, and the parts that have been added. It is desirable to cancel parts that are no longer needed if you can contact the supplier immediately. If it cannot be cancelled, the cost of the parts will rise, and depending on the situation, there will be a significant deficit and will face a serious business crisis. In addition, if contact is made early, it was possible to cancel, but the contact was delayed (for example, when contact was made late, manufacturing was already completed at the supplier), it may not be possible to cancel. In this case, it is not desirable for the environment if the unnecessary parts are discarded.

  Further, if parts to be ordered additionally are decided promptly and are not ordered, in the case of a part with a long delivery date, all parts may not be assembled at the time of assembly, resulting in a delivery deadline. The company will be forced to respond to delays in delivery, leading to higher costs. As a result, employee morale also declines. If the morale of employees declines, orders won't increase, resulting in lower costs and higher costs. These vicious circles jeopardize corporate management.

With respect to this point, a method of providing an examination / approval section has already been introduced for generator production management (see Patent Document 1). However, it does not show an organizational response method when the customer's intention or the like changes as described above.
JP 2004-192352 A

  The following effects can be expected by using the production management apparatus according to the invention described in (1). First, in order to complete the product in a short time limit, even when parts are ordered in advance, at least the ordered parts ordered in association with the product number ordered in the storage means are stored. Thereafter, even when the design is changed due to a change in the customer's intention or the like, the changed parts table is created from the CAD data changed by the changed parts table creating means. Next, the canceled part and the additional ordered part are calculated by comparing the part included in the changed part table created by the changed part calculating unit with the ordered part stored in the storage unit. Is done. Next, the calculated cancel part and additional order part are displayed on the display means. By displaying, the user of the production management apparatus can accurately grasp the canceled parts and the additional ordered parts that need to be specifically dealt with even when the design is changed due to the customer's intention or the like. As a result, the user can quickly investigate whether or not the canceled part can be canceled by looking at the displayed content. As a result, even when there is a problem such as a change caused by a customer request, it can be appropriately handled.

  By using the production management apparatus according to the invention described in (2), in addition to the means described in (1) above, input of CAD data is received by the input receiving means. Thereafter, a production parts table is created from the CAD data received by the production parts table creation means, and an ordering part associated with the product number is calculated by the ordering part calculation means based on the created production parts table. As a result, in addition to the effect described in the above (1), the user can appropriately arrange the advance ordering parts.

  By using the production management device according to the invention described in (3), cancelability information is acquired for the canceled part displayed by the acquisition means. More specifically, the user can make an inquiry to a parts vendor or the like as to whether cancellation is possible, and the result can be input to the production management apparatus according to the present invention. Then, a cancel slip for parts that can be canceled and a slip for additional order parts are issued by the slip issuing means. As a result, in addition to the effects described in either (1) or (2) above, even when there is a problem such as a change due to a customer request, the user can cancel parts that can be canceled quickly and place additional orders. Parts can be arranged. If you contact early, you can cancel the problem, but you can't cancel it because it was delayed. Further, the user can recognize and order an additional part to be ordered from information automatically displayed immediately after the change input. As a result, in the case of a part with a long delivery time, there is a possibility that all parts may not be assembled at the time of assembly, and there is a high possibility of avoiding a problem that delays the delivery time. In addition, when the desirable configuration of the present invention is adopted, parts that can be diverted as parts that are canceled or canceled are cancelled, and inventory processing is performed, so that parts to be discarded can be reduced.

  Further, by causing the computer to read the production management program according to the inventions (4) to (6), a similar effect can be expected by causing the same means as those of the inventions (1) to (3) to function.

  Further, by causing a computer to read a computer-readable recording medium in which the production management program of the invention of (7) is recorded, the same means as those of the inventions of (1) to (3) are made to function in the same manner. The effect can be expected.

  Alternatively, the same effect can be expected by the production management method using the computers of the inventions of (8) to (10).

  Here, the product number refers to a production number, which is a number assigned for manufacturing management. Some companies may abbreviate the production number. Further, the release of the product number means that the relationship with the product number stored in the storage means in association with the part is separated from the product number. For example, the serial number stored in association with the part is changed to another symbol.

  According to the present invention, for example, in the case of a one-piece product, in order to shorten the time limit from start to completion, when ordering parts in advance, and then changing according to the customer's intention, etc., It is possible to accurately extract changed parts and unnecessary parts and reflect them in production management. As a result, it is possible to prevent the deadline from the start to the completion from being delayed due to the change. In addition, an increase in cost due to the change can be reasonably suppressed. Furthermore, since it is possible to minimize the disposal of unnecessary parts, it is also environmentally preferable.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. This is merely an example, and the technical scope of the present invention is not limited to this.

  FIG. 1 is a block diagram showing the configuration of a production management apparatus 1 according to the present invention. The production management apparatus of the present invention is preferably realized using a computer. The control means 11, the storage means 12, the display means 14, and the input receiving means 13 are connected via the bus 15, and the control means 11 controls the entire production management apparatus. For example, the program stored in the storage means 12 is stored. By reading and executing, various means described later are realized in cooperation with the hardware.

  The control means 11 calculates a parts table creation means 112 that creates a design parts table and a production parts table from the input CAD data, and calculates an ordered part in association with the product number based on the created production parts table. The ordered parts calculation means 113, the changed parts table creation means 114 from the CAD data of the changed design drawing, the parts included in the created changed design parts table and the ordered parts stored in the storage means 12 are compared. Changed part calculating means 116 for calculating the canceled parts and the additional ordered parts including the quantity, an acquiring means 117 for acquiring the cancelability of the displayed canceled parts, a cancelable part cancellation slip and an additional ordered part slip And a slip issuing means 118 for issuing

  The storage means 12 can be realized by a hard disk or a semiconductor memory, and stores ordered part information and other information necessary as a production management device. The input receiving unit 13 can be realized by a keyboard, a scanner, or an input receiving unit (for example, LAN) using a communication line. The display means can be realized by a liquid crystal display, a cathode ray tube CRT or the like.

FIG. 2 is a flowchart showing a conceptual operation of the production management apparatus 1 according to the present invention. 3 to 11 show the contents displayed by the display means 14 in the production management apparatus 1. FIG.
Basic design is usually performed for single-product products. The basic design is performed on the basic means and structure of the machine or equipment to be produced. In addition to the basic design, so-called long delivery parts and long delivery materials are selected that require a long delivery time from ordering to delivery. When the basic design is completed, the CAD data is input from the input receiving means 13 to the production management apparatus 1 (S110). A design parts table is created from the input CAD data (S120), and a production parts table incorporating production conditions is created from the design parts table (S130).

  FIG. 3 shows an example of a design part configuration, a production part configuration, and a production part table converted from CAD data. As shown in FIG. 3, the relationship between the part and the unit is clarified by graphically displaying the relationship between the design part configuration and the production part configuration on the display means 14. As shown in FIG. 3, the design part configuration and the production part configuration may be different due to production convenience. For example, in the design part configuration, the part V belongs to the C1 unit, but in the production part configuration, the part V belongs to the C2 unit. An example of the production parts table is shown in the lower part of FIG.

  In the next process, since it is the first process, the process of change “No” is performed (S140). If the change is “No”, the process of issuing an arrangement slip from the production parts list (S150) will be described. FIG. 4 is an input screen for inputting a new product number for the first time. As shown in FIG. 4, for example, the item code “C”, the product number “SEI01”, the quantity “1”, and the scheduled completion date “200505023” in the production parts table are input. When the execution button after confirmation is clicked, an arrangement parts list (before fetching) as shown in FIG. 5 is displayed. If there is no problem checking this screen, the user clicks another button (not shown), and a screen as shown in FIG. In FIG. 6, it is understood that the product number “SEI01” has been taken in by changing the status from “0” to “1”.

  When the production number “SEI01” is taken in, next, the presence / absence of the arranged parts is checked (S160), and since it is “pear” at the beginning, the preceding part arrangement (S210) of the production management apparatus 1 is performed, and the storage means 12, arrangement part information is stored in association with the product number “SEI01” (S220).

  Next, when the detailed design is completed, CAD data is input in the same manner as in the basic design (S110). The input CAD data is processed in the same manner as in the basic design (S120, S130). After that, since there is no change (S140), the arrangement parts are taken from the production parts table (S150). Thereafter, the presence / absence of arranged parts with the same product number is checked (S160), and since it is “ant”, additional parts are arranged (S310), and the arranged part information is stored in the storage means 12 in association with the product number. (S320). If there is no change or the like, the production management of this production number is completed by this process.

  However, as stated above, the specification or design changes for various reasons. When a change occurs, change design is performed. When the change design is completed, CAD data is input from the input receiving means 13 (S110). Similarly to the above, a design parts table is created from CAD data (S120), a production parts table is created from the design parts table (S130), and a modified production parts table as shown in FIG. 7 is created. The sub-unit C1 of the diagram number C1 whose child diagram number is “V” before the change (FIG. 3) is “V2” in the example of FIG.

  Next, since there is a change (S140), processing of additional parts and unnecessary parts is performed (S410). As shown in FIG. 8, a change reflection screen is displayed on the display unit 14. When the execution button is clicked, an arrangement parts list (1 after change) as shown in FIG. 9 is displayed on the display means 14. In the example of FIG. 9, the status “9” is displayed to indicate that the part V of the branch number 5 is no longer necessary, and the part V2 of the branch number 7 may be an additional part that needs to be arranged. It becomes clear by displaying the status “0”. That is, the production management apparatus 1 automatically searches based on the information stored in the storage unit 12, and unnecessary parts and additional parts are displayed on the display unit 14.

  For the unnecessary part of branch number 5, information on whether or not the changed unnecessary part can be canceled is acquired from the acquisition unit 117 (S430). If the investigation result is not cancelled, it is investigated whether or not the part can be used for other purposes (S435). If the check result can be canceled, the status of branch number 5 is changed to “7” as shown in FIG. If cancellation is not possible and diversion is possible, the production number is released, and the status of branch number 5 is changed to “8” as shown in FIG. If cancellation is not possible and other diversion is not possible, the status of branch number 5 is changed to “6” (not shown).

  After the above processing is performed, slips necessary for cancel arrangement (S440), inventory processing (S450), and disposal processing (S460) are issued based on the status information for the unnecessary part V of branch number 5. Issued by the means 118 and the information is stored in the storage means 12.

  For the additional part of branch number 7, the additional part arrangement (S420) is made for the part V2 of branch number 7 with the status "0". That is, the order issuing slip is issued by the slip issuing means 118, and the information is stored in the storage means 12 in association with the product number.

As described above, even when there is a change from the customer by the production management device 1, it is possible to take a measure corresponding to the changed content quickly. As a result, it is possible to minimize inconveniences such as an increase in cost for the change and a delay in completion.
In particular, even in a single-product product, it is possible to reliably execute processing such as cancellation of a changed part, additional ordering, or inventory. As a result, it is possible to accurately estimate the change cost.
As a result, employee morality is improved. In addition, since it is possible to reduce the number of parts to be discarded as compared with a case where a so-called donburi account is used, it is possible to prevent environmental destruction due to waste disposal.

In the above example, the production management apparatus has been described. However, it can be realized by installing a production management program having the means described in the production management apparatus and causing the computer to function as the means.
It can also be realized by causing a computer to read a computer-readable recording medium in which such a production management program is recorded, installing the production management program, and causing the computer to function as a means.

  It can also be realized by installing a computer program having equivalent means in a computer having the same performance as the above production management apparatus and using it by the method as described above.

  As mentioned above, although demonstrated using embodiment of this invention, the technical scope of this invention is not limited to the range as described in the said embodiment. Various modifications or improvements can be added to the above embodiment. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention. For example, the production management apparatus has been described as an example of a computer, but a system employing a digital signal processor instead of a CPU may be used. In addition, although an example of management of single-product production has been described, it is applicable not only to single-product production but also to small-scale or medium-scale production management.
