なる。2. Description of the Related Art In a production system, in order to perform a dynamic simulation for predicting the future from the current state, it is necessary to accurately grasp which product is in which process as an initial value. For this purpose, the FROM-TO information for moving the product based on the manufacturing process of the product and the moving method between the processes, and the timing information of the actual movement from the sensor attached to the manufacturing equipment are fetched to move the product. You need a tracking system to manage.

が多大になるという問題がある。On the other hand, as a method that does not depend on a program, there is a method of attaching an ID code such as a bar code to a product, attaching an ID recognition device to each manufacturing facility, and reading the product in each facility. However, this method requires data management using the ID code as a key, and also requires an ID recognition device for each manufacturing facility, resulting in a large cost.

状況や製品の仕掛り状態を把握することができる。In order to solve the above-mentioned problems, the production data management method according to claim 1 adds an ID card capable of writing data for each product to be assembled and processed. , The product name and the manufacturing process are written in advance on this ID card, and the data writing device provided in the manufacturing facility for assembling and processing makes the manufacturing facility name on the ID card of the product being processed by the manufacturing facility. ,
The work start time and the work end time are written. As a result, by reading the information on the ID card, it is possible to grasp the operating status of the equipment and the in-process status of the product.

書き込むことができる。In the production data management method according to the second aspect, an ID card capable of writing data is added to each product to be assembled and processed, and the product name and the manufacturing process are added to the ID card in advance. In addition to writing, the data writing device provided in the manufacturing facility for assembling and processing writes the manufacturing facility name, the work start time, and the work end time in the ID card of the product being processed by the manufacturing facility, and thereafter, If the product is placed under the control of a manufacturing facility that does not have a data writing device, the processing time at the current manufacturing facility is set to the work end time written on the ID card at the preceding manufacturing facility that has a data writing device. This is added to obtain the work end time at the current manufacturing facility. Thus, for a manufacturing facility without a data writing device, the work end time can be determined based on the standard processing time, and this time can be written in the ID card by the manufacturing facility having the subsequent data writing device. .

に構成されている。On the other hand, 31 and 41 are manufacturing facilities, and the product 10 to which the above-mentioned ID card 20 is attached moves between these manufacturing facilities 31, 41, .... The manufacturing facility 31 is provided with a data writing device 32, and the ID of the product 10 under the control of the manufacturing facility 31
The card 20 is configured to write the work start time and the work end time such as processing and assembly by the equipment 31 together with the equipment name.

れるものである。In the data writing area 21 of the ID card 20, the product name, manufacturing process (used equipment (used machine), processing time) and the like are written in advance as shown in the figure.
Each time 0 is placed under the control of each manufacturing facility, the facility name, the work start time, and the work end time are sequentially and additionally written.

To the work end time in 1, the known processing time in the manufacturing equipment 41 (including the moving time from the manufacturing equipment 31 to the manufacturing equipment 41) is added to obtain the work end time,
It suffices if the manufacturing facility having the subsequent data writing device writes this time on the ID card 20 using the data writing device. Further, if the movement time between the equipments 31 and 41 is known, the work end time of the manufacturing equipment 31 to which the above movement time is added may be further recorded as the work start time of the manufacturing equipment 41.

It is possible to grasp the operating status of equipment. Regarding the in-process status of products, only the work start time is recorded for a certain equipment, and the work for which the work end time has not been recorded is the product in process for that equipment. It can be judged that the difference between the two is the in-process time.
Therefore, it is suitable for performance management and real-time monitoring of the production system.

品）や搬送機器などの移動物に対応させている。By the way, a simulator based on a Petri net composed of a place, a transition, a token, and a timer is often used for the dynamic simulation of a production system. In this case, a place corresponds to a manufacturing facility, a transition corresponds to an operation, and a token corresponds to a moving object such as a product (part) or a carrier device.

You need to specify which place it is in. Therefore, according to the embodiments of the invention described in claims 1 and 2, the manufacturing facility and the in-process time for each product are obtained, and the token is generated in the place on the simulator corresponding to the manufacturing facility. Then, the clock of the timer is set to create the initial state of the simulation, and the future state of production prediction or the like may be simulated from the present state.
