Description

Method, device and system for determining production equipment path, storage medium and terminal

Technical Field

The present application relates to the field of production control. In particular, the present application relates to methods, apparatuses, systems, storage media, processors and terminals for determining a production device path.

Background

Before the factory starts production, the production process needs to be determined to produce the product. Generally, a manufacturing process includes a plurality of manufacturing steps that are performed sequentially from a first step to a last step to complete the manufacturing. For example, if product P100 is to be produced, production steps 10, 20, 30, 40 and 50 need to be performed in order. Wherein step 10 is used for the pre-assembly of the product P100, both the apparatus M10 or M11 can be used for the pre-assembly of this step 10, with pre-assembly times of 10 minutes and 11 minutes, respectively; step 20 is used for the assembly of the product P100, and both the apparatus M20 or M21 can be used for the assembly of this step 20, with the time required for assembly being 12 minutes and 8 minutes, respectively; step 30 is used for testing product P100, and devices M30, M31 or M32 can be used for testing step 30, and the time required for testing is 15 minutes, 12 minutes and 20 minutes respectively; step 40 for the spray painting of the product P100, either the apparatus M40 or M41 can be used for the test of this step 40, the times required for the test being 11 minutes and 8 minutes, respectively; step 50 is used for packaging of product P100 and device M50 can be used for packaging of this step 50, the packaging time being 3 minutes. In a production process comprising these 5 production steps, a specific device is required to complete the corresponding production. Since in some steps more than two devices can be used for the corresponding production, a selection of the device for each production step needs to be made when performing this production step. After selecting these devices for production, the production sequence will proceed from the device selected in each production step to the device selected in the next production step, up to the device selected in the last production step. The sequence of equipment used in such a production process is referred to as a production equipment path. For example, one possible production equipment path is M10-M20-M30-M40-M50. In the above example, there may be 24 production equipment paths of 2 × 2 × 3 × 2.

For an operation team in a plant, an important task is to select which production equipment path to perform a production process. The selection of the correct production equipment path is critical to meeting business objectives such as reducing production costs, on-time delivery, and reducing inventory.

However, selecting an optimized production equipment path is challenging for the operations team. Typically, the selection of the production equipment path is made manually or with software support based on the highly simplified environment of the plant (e.g., all equipment is available). When performing production, the efficiency of the selected production equipment path is often not as desired due to the complexity in the actual operation.

Detailed Description

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or modules or elements is not necessarily limited to those steps or modules or elements expressly listed, but may include other steps or modules or elements not expressly listed or inherent to such process, method, article, or apparatus.

The calculation method of the production equipment path can adopt an equipment virtual model to carry out simulation. In the device virtual model, a plurality of virtual devices are provided corresponding to the actual production devices, each virtual device representing one actual production device, and in the virtual model, the virtual devices execute processing of the corresponding production device, thereby simulating the production device. Such simulation of production equipment may be used to provide simulation results for a production process to determine production-related data such as production time or production expense required to perform the production process for each production equipment path. However, in such simulation, the simulation result obtained by simulating the production equipment with the virtual equipment cannot truly reflect the production-related data of the actual production process, because the production equipment may not guarantee 100% of the availability rate because other products need to be produced, and thus the simulation result may deviate from the actual situation.

For example, the virtual model of the product P100 is configured to perform simulation of the production process, and the configuration of the equipment is as follows.

Name of the device	Availability ratio (percentage)
M10	100.00
M11	100.00
M20	100.00
M21	100.00
M30	100.00
M31	100.00
M32	100.00
M40	100.00
M41	100.00
M50	100.00

TABLE 1

By adopting the virtual model, an optimized production equipment path which meets the following production requirements is found out:

-a product quantity of 100;

the production time is minimal.

All production equipment paths (24 in total) are simulated, and the following simulation results (the result of 15 paths with the shortest production time) are obtained according to the production time:

pathname	Production time

……	……

TABLE 2

From the above table, the optimal production equipment path is path 10, as shown in line 2 of table 2, with a production time of 20:29:30.0000, i.e., 20 hours, 29 minutes, and 30 seconds. The plant route was M10-M21-M31-M41-M50.

However, since the actual production equipment may not have the availability of 100%, the optimal production equipment path obtained according to the simulation result may be different from the actual optimal production equipment path.

According to an embodiment of the present application, a method of determining a production device path is provided. FIG. 1 is a flow chart of a method of determining a production device path according to an embodiment of the present application. The method for determining the production equipment path according to the embodiment of the application comprises the following steps:

step S101, configuring the availability rates of one or more virtual devices corresponding to one or more production devices as the availability rates of the corresponding production devices, and simulating the corresponding production devices by the virtual devices. In the embodiment of the application, the virtual device simulating the corresponding production device is configured as the availability of the production device, and in the simulation process, the virtual device runs according to the state conforming to the actual availability of the production device so as to accurately simulate the production process.

For example, the table below configures the availability of virtual devices according to the availability of production devices.

Name of the device	Availability ratio (percentage)
M10	50.00

M11	40.00
M20	50.00
M21	55.00
M30	50.00
M31	30.00
M32	40.00
M40	30.00
M41	35.00
M50	60.00

TABLE 3

After the availability ratios of the virtual devices are configured as shown in table 3, the virtual devices in the virtual model conform to the states of the actual Production devices, and the virtual model becomes a Production Digital Twin (Production Digital Twin) of the Production devices of the Production process.

Step S103, a plurality of production equipment paths are calculated according to one or more virtual equipment, and each production equipment path represents the sequence of the production equipment adopted by the production process. According to all available devices in the production process, a plurality of production device paths are calculated from the device used in the first production step to the device used in the next production step to the device used in the last production step according to the production steps. For example, in the first production step, M10 or M11 may be used, and M10 is set to be in one fab path and M11 is set to be in the other fab path. In the production facility path of M10, its next path point may be M20 or M21, yet another next path point may be M30, M31 or M32, yet another next path point may be M40 or M41, and the final path point is M50. The selection of each waypoint will result in a different production facility path.

Step S105, generating a simulation result according to the availability of one or more virtual devices and based on each production device path, wherein the simulation result represents production related data of each production device path. After the virtual equipment is configured according to the availability of the production equipment, the simulation of the production process is performed, the virtual equipment operates according to the configured availability, and a simulation result is generated for each production equipment path, wherein the simulation result comprises production related data of production time required by each production equipment path to perform the production process. For example, an optimized production equipment path that meets the following production requirements is still found:

-a product quantity of 100;

the production time is minimal.

The simulation process will generate the production time required to produce 100 products per production equipment path.

And S107, sequencing the paths of the plurality of production equipment according to the sequencing conditions and the simulation result. After the simulation result of each production equipment path is obtained as described above, in order to find out the production equipment path with the shortest production time, the production time is used as a sorting condition, and the production time data in the simulation result is used to sort the production equipment paths as shown in the following table (showing the results of the 15 paths with the shortest production time).

Pathname	Production time
8	2:06:14:31.4647
20	2:06:37:06.5387
2	2:07:06:32.3767

TABLE 4

As can be seen from table 4, after the availability ratios of the virtual devices are configured according to the availability ratios of the production devices, the obtained sorting result of the production time is different from the result of the unconfigured availability ratio.

And step S109, determining an optimized production equipment path according to the sequence. For the production requirement with the shortest production time, it can be seen that the path of the production equipment with the shortest production time can be determined to be the path 8 after the production requirements are sorted according to the production time. The devices in path 8 are M10-M21-M30-M41-M50.

According to an exemplary embodiment of the present application, a method of calculating an availability of a production device and then performing a determination of a production device path is also provided. FIG. 2 is a flow chart of a method of determining a production device path according to an exemplary embodiment of the present application. As shown in fig. 2, according to an exemplary embodiment of the present application, before determining the production equipment path, step S201 is performed to obtain operation data from existing data of the production equipment or through the internet of things. The existing data of the production facility may be operational data known to the production facility. The internet of things can be used to obtain its operational data directly from production equipment. Then, step S203 is performed to calculate the availability of one or more production devices according to the operation data, wherein the operation data represents the occupied or available information of one or more production devices. The production apparatus is occupied when producing other products, and cannot be used as a production apparatus for producing another product, and can be used when the production apparatus is idle. Alternatively, the production equipment may not be available for production of the product for some time due to failure, maintenance, or other reasons that may occur in a factory environment, such that it is only available for a portion of the time. The availability of a production facility may be the ratio (percentage) of the actual production time that the production facility is able to participate in the production of the product to the total production process time. Thus, based on this operation data, the availability rate at which the production equipment can be used can be calculated. In this manner, availability of virtual devices that simulate production device paths is provided.

Then, the following steps are carried out:

step S205 configures the availability rates of one or more virtual devices corresponding to one or more production devices as the availability rates of the corresponding production devices;

step S207, calculating a plurality of production equipment paths according to one or more virtual equipment, wherein each production equipment path represents the sequence of production equipment adopted by a production process;

step S209, generating a simulation result according to the availability of one or more virtual devices and based on each production device path, wherein the simulation result represents production related data of each production device path;

and step S211, sequencing the paths of the plurality of production equipment according to the sequencing conditions and the simulation result.

The above steps are consistent with steps S101 to S107 shown in fig. 1, and are used for configuring virtual devices using the available rate, performing simulation of a production process, and sequencing production device paths (for example, in an order of short production time to long production time or less production cost to much production cost), which are not described herein again.

After sorting, a list of production related data corresponding to the production equipment paths sorted according to a predetermined order can be visually seen. Step S213 is then performed to determine an optimized production device path according to the ranking. The order of the devices in the production device path may be displayed on a display for human reference.

The optimized production equipment path may be determined from the above ordering in different ways for different production needs.

For production demands where the time required to produce a certain number of products is the shortest, the production time may be used as a sorting condition. After step S209 is completed, a simulation result is obtained, the simulation result shows the production time corresponding to each production equipment path, and in step S211, based on the production time shown by the simulation result, the production equipment paths may be sorted in the order from short to long production time, and the highest-ranked production equipment path shown in the sorting of the production equipment paths is determined to be the production equipment path with the shortest production time, that is, the optimized production equipment path meeting the production requirement.

As another example, for a production demand that requires the least expense to produce a certain number of products, the production expense may be adopted as the sorting condition. After step S209 is completed, a simulation result is obtained, the production cost corresponding to each production equipment path is displayed in the simulation result, and in step S211, based on the production cost shown in the simulation result, the production equipment paths may be sorted in the order of the production cost from a few to a large number, and the production equipment path with the highest sorting shown in the sorting of the production equipment paths is determined to be the production equipment path with the shortest production cost, that is, the optimized production equipment path meeting the production requirement.

According to an exemplary embodiment of the present application, the production related data includes production time and/or production cost, and may also include data related to other production processes, it will be understood that other production related data may also be used as a sorting condition for sorting the production equipment paths, and only data concerned in the production processes need to be used as a sorting condition, so that a required optimized production equipment path may be determined after sorting.

In addition, according to the embodiment of the application, the optimized production equipment path can be further screened by adopting the constraint condition. For example, only a portion of all production equipment paths are selected, while the unselected portions do not meet production requirements. A method of further screening the optimized production device paths is shown below by way of example, screening a plurality of production device paths that meet the constraints as a basis for determining the optimized production device paths before determining the optimized production device paths according to the ranking.

The production requirements are:

-completing production 8 hours before a predetermined time to guarantee delivery of the product;

not completing production 24 hours before the predetermined time to reduce inventory and inventory costs.

After simulating the production process, the production equipment paths are sorted in order of the remaining time to the predetermined time from short to long (sorting conditions) while showing other production related data (e.g., production time and production cost), for example, as shown in the following table:

pathname	Production time	Time remaining until predetermined time	Cost of production
