[0011]
Hereinafter, an example of a manufacturing consignment process by the manufacturing consignment system will be described with reference to FIGS. In performing the manufacturing consignment process by the manufacturing consignment system, first, the member registration unit 11 that registers the contact information of the fabless 3 and the fab 4 in the database 18 will be described. FIG. 3 shows the registered contents. There is fabless member information 181 for registering fabless contact information and fabless member information 181 for registering fab contact information, such as member ID, company name, address, person in charge, password, telephone number, e-mail address, course number, etc. There are items. Here, the member ID is a dedicated code automatically issued by the member registration means 11 so as not to overlap with existing fabless 3 or fab 4 members, and is used to identify the other party when using the manufacturing consignment system thereafter. belongs to. Next, the screen of the member registration means 11 will be described with reference to FIG. First, a fabless contact information is entered on the fabless member registration screen 31. With the registration button, the input result is registered in the fabless member information 181, and at the same time, the membership registration result 32 such as a member ID and a password is notified to the input mail address. Note that the notification means may be a letter or a facsimile.
[0012]
Subsequently, information exchange performed between the registered fabless 3, the fab 4, and the server 1 of the manufacturing consignment system will be described.
[0013]
First, referring to FIG. 5, a processing procedure associated with the manufacturing consignment procedure will be described. The fabless 3 who wants to outsource manufacturing inputs the fabless member ID and password obtained by the member registration means 11 and logs in to the server 1 of the outsourced manufacturing system (1). The server 1 refers to the fabless member information 181 based on the fabless member ID and the password, performs an authentication process for deciding whether or not the result is acceptable (2), and notifies the fabless 3 of the authentication result (3). Here, if there is an error in the fabless member ID or password, the authentication is rejected, and the fabless 3 cannot perform the following procedure. If the authentication result is successful, the fabless 3 can use the specification registering means 12 to register the specification of the product to be outsourced (4). Main registration contents here are shown in the product specification 183 of FIG. It consists of the product name, the component name of the product, the quantity, and the drawing. Subsequently, the product manufacturing specification and the specification of the jig / equipment used in the manufacturing process are registered (5). Main registration contents here are shown in jig specification 184 and manufacturing specification information 185 in FIG. The jig specification 184 includes a jig name, a jig size, and power consumption. The manufacturing specification information 185 includes a product name, a work order, work contents, a standard work time, a part name, and a jig name. FIG. 7 shows an example of the definition screen of the manufacturing specification information 185. The manufacturing specification information definition screen 5 includes a work moving image reproducing unit 51 and a work procedure input unit 52. The work moving image reproducing unit 51 can reproduce and display a manufacturing method of a product photographed in advance. The work procedure input unit 52 is a part for inputting work contents in order. It is possible to input while confirming the manufacturing method in the work reproducing section 51. The input specifications are stored in the database 18 of the server 1. After the specification registration is completed, the fabless 3 can input an estimate request using the estimate request registration means 13 (6). As shown in the estimate request information 186 in FIG. 6, the input contents include a product name, a quantity, a minimum division quantity, a delivery date, a budget, a bid deadline, and a product delivery destination of the quote to be obtained. The quote request ID, the quote requester, and the time stamp are items that are automatically assigned by the quote request registration unit 13 in order to eliminate erroneous or incorrect inputs. The quote request ID is a code for distinguishing it from other quote requests and is not duplicated. In the item of the quote requester, the fabless member ID entered at the time of login is registered. The quote request registration unit 13 registers the quote request information 186 in the database 18 and, at the same time, notifies the fab 4 registered in the fab member information 182 of the contents of the quote request information 186 shown in FIG. 6 (7).
[0014]
Next, the fab 4 uses the manufacturing method output unit 14 to execute a simulation for inspecting the manufacturing method of the product and evaluating the influence on manufacturing time, work difficulty, and manufacturing cost due to a change in the number of personnel. Build a production line. Specifically, the fab 4 inputs the quotation request ID of the case to be viewed, the fab member ID of the fab 4, the password, and the number of workers, and logs in (8). Based on the fab member ID and the password, the manufacturing method output means 14 performs an authentication process for determining pass / fail with reference to the fab member information 182 (9). Here, if there is an error in the fab member ID or the password, the authentication fails, and the fab 4 cannot perform the following procedure. If the authentication result is successful, the fab 4 is notified of the contents of the product specification information 183, the jig specification information 184, and the manufacturing specification information 185 shown in FIG. Thus, the fab 4 can know a specific method of manufacturing the product. Subsequently, the fab 4 inputs items including the number of workers and the hourly unit price shown in the fab environment information 141 of FIG. 8 in order to simulate and evaluate the manufacturing time, the work difficulty, and the manufacturing cost. Here, the simulation contents when it is assumed that there is an estimation request of the contents shown in the estimation request information 186 of FIG. 8 will be described with reference to FIGS. FIG. 8 is a diagram showing input conditions in the current simulation. The meaning of the contents shown in the estimate request information 181 means that there is an estimate request for outsourcing the manufacture of 10 product names X with a budget of 325 within 75 hours. The component configuration for manufacturing one product X includes X1 and X2 as shown in the product specification information 183, the unit price (budget) is 1, and the manufacturing method is 1 as shown in the manufacturing specification information 185. It is assumed that the operation process is up to 6. A simulation method when a fab with the number of workers indicated in the fab environment information 141 indicating this commission request and the unit price per hour is 1 will be described with reference to FIGS. 9 and 10. FIG. FIG. 9 is a flowchart of the algorithm of the simulation method. FIG. 10 is a diagram (simulation calculation table 142) showing data in a calculation process when the algorithm in FIG. 9 is performed under the input conditions shown in FIG. Specifically, the product specification 183, the manufacturing specification information 185, and the fab environment information 141 of the product registered in the quote request information 186 are read (step 1). Subsequently, the processing of steps 3 and 4 described below is repeated in descending order by the maximum number of work orders (six times in this embodiment) (step 2). That is, when the production line of the fab 4 is a production line in which six operations are performed as six processes and six people perform a flow operation, when the production line is divided into five processes and a production operation of five people is performed, a final production process is performed. More specifically, simulations are respectively performed on the assumption that a single process is performed by a single production line, and the effects of the divided processes such as production time and production cost are evaluated. The data in the simulation process for each process corresponds to each column of the process division number shown in S2 of FIG. In step 2, the manufacturing time, the work difficulty, and the manufacturing cost for the number of process divisions are calculated. The calculation result is shown in S3 of FIG. For example, when the number of process divisions is 6, the manufacturing time y5 is 92, the work difficulty y1 is 6, and the cost y7 is 456. In step 4, one step is reduced while maintaining the balance of the standard operation time for each step. Specifically, one location where the sum of two consecutive processes is minimum is extracted, and the processes are consolidated into one. For example, when the number of process divisions in FIG. 10 is changed from 6 to 5, the sum of the standard operation times of the processes corresponding to the work orders 1 and 2 with circles is 6, which is the minimum. , Work orders 1 and 2 are combined into one as shown in S4. In step 5, the process is repeated until the number of process divisions becomes 1, and the process ends. The production method output unit 14 notifies the fab 4 of the simulation result (12). FIG. 11 shows the simulation result 143. It is a screen for comparing and displaying the simulation result including the manufacturing time y5, the work difficulty y1, and the cost y7, and the requested delivery date (remaining time), budget, and worker level for each number of process divisions. Simulation results from a production line in which six workers share work in six processes to a case in which six production lines are prepared by one person as one process can be compared and evaluated with one eye. If the number of workers is not divisible by the number of processes, the number is rounded down. For example, when six workers try to operate a manufacturing line of five processes, the cost is calculated by reducing the number of staff to five because there is one more worker. It can be seen that the number of process divisions of the production line that satisfies the budget and the delivery date is one or two. If the worker level of the fab is assumed to be 20, it is understood that it is better to select two process divisions. This makes it possible to evaluate in advance whether or not the fab can undertake manufacturing consignment.
[0015]
After the simulation is completed, the fab 4 can input an estimate using the estimate answer registering means 15 (13). As shown in the estimate information 187 in FIG. 6, the input contents include the contract term, price, quote respondent, and quantity of the quote request ID to be answered. The quote ID, the quote respondent, and the time stamp are items that are automatically assigned by the quote response registration unit 15 in order to eliminate erroneous or illegal inputs. The quote reply registering means 15 registers the contents of the quote reply information 187 in the database 18 and, at the same time, extracts the contact information of the fabless 3 corresponding to the quote request ID from the fabless member information 181 and returns the quote reply to the fabless 3 The contents of the information 187 are notified (14). The fabless 3 uses the contract registration means 16 to determine and register a manufacturing consignee (15). FIG. 12 shows a contract registration screen 33 for determining a manufacturing consignee, which is roughly classified into two types: a manufacturing consignment content 33a and a quote answer list 33b. The quote answer list 33b can be sorted in the order of earlier contract or price. This screen example is an example in which three fabs have provided quotation responses to a project scheduled to outsource production of 10 products X (minimum number of divisions: 2) by February 27. Note that the minimum division number indicates the minimum quantity that may be used to divide the order quantity. For a fab with an estimate ID of ddd, ten units can be entrusted in a lump, but circles are entered in the contract column so that two inexpensive quotation IDs are entrusted to a bbb fab and a ccc fab. The contract registration means 16 registers the contract ID, the estimate ID, and the contents of the contract date shown in the contract information 188 of FIG. The message is notified (16). After shipping the product, the fab 4 performs a shipping process (input of a shipping date) using the progress status registration means 17 (17). After updating the item of the shipment date in the contract information 188, the progress status registration means 17 notifies the fabless 3 of a message of the acceptance request (18). After acceptance, the fabless 3 performs an acceptance process (input of an acceptance date) using the progress status registration means 17 (19). After updating the item of the acceptance date in the contract information 188, the progress status registration unit 17 notifies the fabless 3 and the fabless 4 of a message of the completion of the consignment contract (20). As a result, business opportunities can be expanded even with small fabs that can be manufactured at low prices but cannot be mass-produced, and fabless can also trade with fabs with low prices.
[0016]
The progress status registration means 17 accepts complaint information from the fabless 3 or the fab 4 at any time by e-mail or WEB, and records the result in the database 18 as needed. As a result, it is possible to forcibly withdraw members who have many complaints or who have been notified of malicious acts.
[0017]
Lastly, an example of a business flow of the manufacturing consignment system will be described with reference to FIG. The fabless 3 and the fab 4 sign a confidentiality contract when the fabless 3 and the fab 4 register as members. However, it is not necessarily required. The fabless 3 and the fab 4 input business transaction data required for the consignment contract. The server 1 implements related services provided for the fabless 3 and the fab 4. The server 1 charges from the fab 4 as the information provision fee. The breakdown of the billing is a basic fee for periodically collecting a fixed fee and a service fee according to the transaction price at the time of contract establishment. Any of these may be free. In addition, the fab 4 that has contracted the manufacturing consignment delivers the product to the fabless 3. Fabless 3 pays Fab4 for the price. Further, as a charging method, when the estimated price is lower than the budget, the profit amount can be set within the range of the difference. This profit amount is added to the estimated price and presented to fabless. The profit amount obtained from the fabless is distributed between the fab 4 and the server 1.
