Description

Automated Order Decision Method Using On-site Specification Sheet {AUTOMATIC FIELDWORK ORDER DECISION SYSTEM USING BILL OF PROCESS}

The present invention relates to a method for on-site automatic order determination using a BOP. In particular, in a sequential number control system (SNS), a new order is generated from a customer using a BOP. The present invention relates to an on-site automatic order determination method that allows an order to be determined based on load information of each process, whether or not a received order is received.

Traditionally, enterprise resource planning (ERP) packages have been introduced as information system software used by manufacturers to determine new orders, and production inventory management uses material resource planning (MRP) modules. This MRP is a plan-driven module developed in the United States, developed around inventory, which has a problem in that the logic is complicated and the calculation time is not used effectively in the manufacturing site.

In order to solve this problem, a sequential numbering control system (SNS) developed in Japan is used, which accumulates in the MRP part development method (SN: cumulative number of consecutive numbers). This system was developed based on the progress management that dualized the planning and performance to simplify the information processing logic, and developed the parts of the Bill of Material (BOM) to calculate the requirements of the lower parts. Since it is possible to easily establish a plan for each production process and a plan for each subcontractor, it is used as a production inventory management module of the ERP.

A detailed description of the cumulative management system described above is as follows.

The SNS is divided into product plan, part plan, process plan, and load plan. First, product plan is for example A and B as shown in [Table 1]. Suppose the order of a company producing a product comes in and its product-specific plan is configured as shown in Table 2. To calculate the output of the day with only SN, you can subtract the previous day's SN from that day's SN.

Date ＼ Products One 2 3 4 5 6 7 8 9 10 A 5 0 10 10 0 15 0 0 20 0 B 0 10 0 5 0 15 0 0 0 5

Secondly, the part-specific plan is planned through the part development given the product-specific plan, and as shown in FIG. 1, if the part configuration of the product is shown (the values in parentheses in FIG. 1 indicate the unit requirements, The value in the arrow indicates the procurement time. The part-specific plan is as shown in [Table 3].

Date Part One 2 3 4 5 6 7 8 9 10 A 5 5 15 25 25 40 40 40 60 60 AA 30 50 50 80 80 80 120 120 AB 45 75 75 120 120 120 180 180 ABA 240 240 240 360 360 ABB 240 240 240 360 360

Third, the process-specific plan is planned by fitting the part-specific plan and through the part master information. When the part information is given as shown in [Table 4], the process of the part has the part code and the process code of the part information. In order, data is stored in each process by working date. At this time, the quantity made in the parts plan is added to the existing plan SN to maintain the total.

Finally, the fourth is a load plan, which is carried out simultaneously with the process plan, and the load amount is calculated based on the part code, the process code, and the labor of the parts master. That is, for example, if the process M2 load plan of [Table 4] is made as shown in [Table 5], the load is performed in all fields during the plan reflection period for each part (to be accumulated by the product of parts quantity and parts labor). ).

However, the above-described prior art uses the infinite capacity method first, and the infinite capacity method is a method that mechanically schedules all the new tasks that can be achieved within the delivery date, and is currently in progress or available. There is a problem that it is not suitable to plan because it does not consider at all (ie, it informs the load schedule that the load situation will be like this if it is to be produced according to the delivery date), and secondly, it is necessary to consider working time only considering lead time. The procurement time (consisting of setup time, processing time, travel time, and waiting time) is always used as a fixed value even though the data is not inherently fixed. Reports are generated that are out of line with the actual site, increasing inventory and making capacity planning impossible Third, when a new order occurs, the order is accepted without a pre-load review and the delivery time may be delayed, thereby degrading the reliability of the company.

Therefore, the present invention was devised to solve the above problems of the prior art, and when a new order is generated from a customer using airlift per part in a method of deducting time using an existing LeadTime using a BOP The purpose of the present invention is to provide a method for judging an order based on load information of each process, whether or not to receive a generated order.

On-site automatic order determination method using the present invention process specification (BOP) to achieve the above object, when a new order is entered from the customer to give the order number of the predetermined format for the order and store the operation numbering Steps; When the order number is assigned in the order numbering step, the parts information for the new order is stored as a list with the bill of material (BOM) information, unit quantity, process information, and production time information for each part based on the part code. BOP list generation step: Based on the BOP list in the BOP list generation step, considering the normal load and emergency load at the same time, the development of each load to aggregate the load information in each load database and the development of the performance load to generate the process progress information BOP deployment step of performing; A load review step of determining whether the order is received by examining the available capacity of the process according to the change of the existing load by the new order; If it is determined that the order is received in the load review step, the additional cost is calculated by negotiating the price with the orderer, characterized in that consisting of the order confirmation step to finally perform the work to confirm the order.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is an exemplary view briefly showing the configuration of the order determination system for applying the present invention, as shown in the SNS production management system server 10 and the web server 20 and the database server 30 The SNS production management system server 10 includes an SNS production / stock management module 11, an order determination module 12, and an information management module 13, and the database server 30 orders 31. , The load 32 and the management database 33, the web server 20 is connected to the production site 21, the subcontractor 22 and the customer 23, respectively.

The order judging system plans a production schedule by sharing basic information such as parts information, BOM information, and production site information from the SNS production management system server 10, and accumulates plan data for each process according to the production schedule. Real-time performance data from each department is input from the web server 20 to calculate the progress, inventory, and arrangement information.In addition, each department uses a personal digital assistant (PDA) to quickly perform performance at a long distance. Or enter bad information.

In addition, the process specification (BOP) (BOP) applied to the present invention as shown in Figure 4 is made of a combination of the individual workman and part processing process information in the component configuration information of the BOM and the component information of the component master, The parts that make up a product are made up of minutes in which process and when to produce them.

Referring to Figure 3 attached to the operation of the embodiment according to the present invention configured as described above are as follows.

3 is an exemplary view showing the overall operation flow of the method for determining the automatic order of the field using the process specification (BOP) of the present invention. The order number assignment method is a combination of a delivery date and a customer code. That is, for example, assuming that the delivery date is 2001.04.10 and the account code is 02, the order number assigned is given as 200104002.

In addition, several different orders can be assigned to the same order number, so that on the final delivery date, the delivery person can easily view the order number and know which date to deliver to which customer. The data can be managed.

When the order number is given in the above, as shown in [Table 6], the parts information for the new order is provided with the bill of material (BOM) information, the unit quantity, the process information and the production time information for each part based on the part code. Save as a list (TempFile).

In [Table 6], the load value is the minute plan value calculated by multiplying the production time per part by the production quantity, and the production quantity is the production quantity based on the unit quantity of BOM.

Based on the BOP list, BOP deployment is largely performed by process and performance load deployment. Among them, BOP deployment creates load list table by aggregating load information in each load database considering both normal load and emergency load. As shown in Table 7, the load list table considers the above two (normal load and emergency load) in consideration of the time phase of the load, and the cumulative planned load (SN) during the time reduction process is accumulated separately for each part. In addition, the total plan SN is accumulated separately from the types of parts to facilitate the management of each part in the target facility.

In other words, the load plan assuming normal operation assumes the amount of work for 8 hours a day, and the emergency work (overtime) is based on the option specified by the user by increasing the capacity of the process. In short, normal work refers to the amount of work performed by the process for eight hours, while overtime work is information that indicates the amount of work done by the process to its fullest extent, and the loads obtained from the BOP list are summarized as planned loads.

In addition, the performance load development is performed to input the performance load when the performance is input to determine the required load of each process, and this performance load is the number of minutes when the operator inputs the quantity compared to the production time per piece information of parts. Is converted. For example, assuming that the production time per part A is 2 minutes, if the operator inputs 200 pieces, the performance load is 2 × 200 = 400, and the performance load is 400. In addition, the performance load is calculated by accumulating the performance load SN and is made up of a bundle on a daily basis. When this performance load is input, the required load is created by [Equation 1] as compared with the planned load SN. The following equation shows the required load

Required Load = Performance Load SN-Planned Load SN1 --------------- [Equation 1]

The role of the demand load is information indicating the progress of the process. If the progress is slow, the demand load is represented as a negative value. If the progress is fast, the demand load is represented as a positive value and the manager identifies how much progress has been made in the process based on the demand load information. Can give appropriate staff appropriate instructions.

[Table 8] is an example of inputting the amount of performance until April 9, 2001. According to this, it can be seen that the progress is slowed due to the small amount of performance load. Made it possible.

Looking at the required load information for each process in Table 8, it can be seen that the performance load SN, the total performance load SN, and the total performance load SN1 exist. The performance load SN is a value accumulated for each part. These values indicate the progress of each part in the target installation. In addition, the total performance load SN is a value obtained by accumulating all the performances in the target equipment without classifying parts, and the total performance load SN1 is a cumulative graph without considering additional work load.

The reason why the total performance load SN1 is required is to prevent the amount of performance of the target equipment from being excessive when the quantity of performance of a specific part is large when additional orders are generated. The demand load described above is also classified into the demand load and the demand load 1, and the demand load is a value indicating the progress of parts in each target process, and the demand load 1 is a value indicating the progress of the equipment.

When the BOP development step is completed, it is determined whether the order is received by reviewing the available capacity of the process according to the change of the existing load by the new order. If it is not possible to make a delivery date, it is possible to specify a re-delivery date by presenting a due date to the customer, and then repeating the execution of the BOP list generation operation. However, if no re-delivery date is specified, the order will be considered canceled and the load list corrected and terminated.

In addition, when there is an additional order, as shown in FIG. 5, when the line indicating the normal plan load SN and the overtime plan load SN is located only below the line representing the maximum work, the additional order is accepted. Reschedule and due dates and order quantities.

If it is determined that the delivery date can be determined, the order is determined to receive the order, and if the additional order is accepted, the cost is calculated in consideration of the additional cost, and the price is finally negotiated with the orderer. Do the work.

However, if price negotiations are not made, the order will be considered canceled and the load list corrected and terminated.

Although the invention has been particularly shown and described with reference to the preferred embodiments, those skilled in the art will appreciate that various modifications are possible without departing from the spirit and scope of the invention. Accordingly, the invention is limited only by the claims.

As described above, the on-site automatic order determination method using the BOP of the present invention can reduce the unnecessary overtime or overtime by converting the infinite capacity method into a finite capacity method, and accurate inventory and Progress information can be secured so that accurate delivery dates can be presented to customers to improve reliability, and minute planning can be shown to on-site process personnel, thereby minimizing responsibilities and minimizing idle time. It is possible to monitor the load level of the process in real time, so that it is possible for the plan reflection person to re-plan according to the situation of each process.
