Description

Device and method for generating a common asset management shell template

[0001] The following examples relate to techniques for managing custom templates, which are non-standard asset templates, in a company or organization.

[0002] The Asset Administration Shell (AAS) is a key concept used in Industry 4.0 and the Internet of Things (IoT). It provides a framework for representing and sharing information about various assets in a standardized format in manufacturing and industrial environments. AAS aims to enhance interoperability, transparency, and efficiency by supporting the digital representation of assets—machines, equipment, products, etc.—in industrial ecosystems.

[0003] AAS can be applied in various industrial fields and has the following main characteristics:

[0004] 1) Digital representation of assets

[0005] AAS digitally represents assets (machines, equipment, products, etc.) to create a virtual representation of real-world objects. This digital representation includes the asset's status, characteristics, operation, and related information.

[0006] 2) Standardized data model

[0007] AAS represents asset information based on international standards. This helps ensure interoperability among various assets without relying on specific platforms or manufacturers.

[0008] 3) Interconnectivity and transparency

[0009] AAS promotes interconnectivity and transparency by providing a standardized method for exchanging and sharing asset information across various systems and processes. This enhances data consistency and reliability across the entire ecosystem.

[0010] 4) Lifecycle Management

[0011] AAS can manage and monitor the asset lifecycle. This means tracking the condition and history of an asset throughout its various stages, including design, manufacturing, operation, and maintenance.

[0012] 5) Diversity of use cases

[0013] AAS can be applied to a variety of use cases, including smart manufacturing, flexible production systems, predictive maintenance, and the implementation of digital twins (digital replicas of assets).

[0014] AAS is being developed by the International Electrotechnical Commission (IEC), an international standards body, and other standards organizations, enabling the adoption of standards-based digital representations across various industries and businesses.

[0015] However, as industries become more sophisticated and each company's assets become more specific, managing corporate assets using standard AAS alone becomes difficult. Therefore, each company is creating and using templates (custom templates) tailored to its needs. This has led to the need for each company to manage its own custom templates.

[0016] The present invention aims to provide a device and method for generating a common asset management shell template.

[0017] A method for generating a common asset management shell template according to an embodiment of the present invention may include the steps of: receiving standard templates and customized templates; converting each of the standard templates and the customized templates into a tree form; generating a standardized customized template tree by changing each of the customized template trees into the form of the standard template tree; generating a master template including all of the standardized customized template trees; assigning a bit vector index to a leaf node included in the master template and assigning a bit value; verifying a bit vector of each of the customized templates; calculating a bit vector distance between the customized templates using the bit vector of each of the customized templates; and generating a common asset management shell template by clustering the customized templates based on the bit vector distance between the customized templates.

[0018] At this time, the step of changing each of the above custom template trees into the form of the standard template tree and generating a standardized custom template tree may include changing each of the above custom template trees into the form of the standard template tree by deleting an attribute from the standard template tree, adding an attribute to the standard template tree, and changing an attribute included in the standard template tree, thereby generating the standardized custom template tree.

[0019] At this time, the step of converting each of the standard templates and the customized templates into a tree form may be performed such that when converting each of the standard templates and the customized templates into a tree form, they can be converted into an ordered tree form.

[0020] At this time, the step of changing each of the above custom template trees into the form of the standard template tree to create a standardized custom template tree may include the step of calculating a compliance score of the plurality of standardized custom template trees when the above custom template trees are changed into a plurality of standardized custom template trees; and the step of removing all but the standardized custom template tree with the lowest compliance score from among the plurality of standardized custom template trees.

[0021] At this time, the step of calculating the above compliance score can be calculated using <Mathematical Formula 1> below.

[0022] [Mathematical Formula 1]

[0023]

[0024] Here, CMS() is the compliance score and AAST i is the ith standard template, TED() is the tree edit distance indicating how much the standard template tree has changed, and SMT ij is the jth submodel template included in the ith standard template.

[0025] At this time, the step of calculating the bit vector distance between the customized templates using the bit vector of each of the customized templates can be performed by performing an exclusive OR on the bit vectors between the customized templates, assigning a bit value to the bit vector, and calculating the added value as the bit vector distance.

[0026] According to one embodiment of the present invention, a device for generating a common asset management shell template comprises: a memory; and a processor, wherein the processor receives standard templates and customized templates, converts each of the standard templates and the customized templates into a tree form, changes each of the customized template trees into the form of the standard template tree to generate a standardized customized template tree, generates a master template including all of the standardized customized template trees, assigns a bit vector index to a leaf node included in the master template, assigns a bit value, verifies a bit vector of each of the customized templates, calculates a bit vector distance between the customized templates using the bit vector of each of the customized templates, and clusters the customized templates based on the bit vector distance between the customized templates to generate a common asset management shell template.

[0027] The above processor can generate the standardized custom template tree by changing each of the custom template trees into the form of the standard template tree by deleting an attribute from the standard template tree, adding an attribute to the standard template tree, and changing an attribute included in the standard template tree.

[0028] At this time, the processor can convert each of the standard templates and the custom templates into a tree form, and convert them into a sorted tree form.

[0029] At this time, when the processor generates the standardized custom template tree, if the custom template tree is changed into a plurality of standardized custom template trees, the processor can calculate the compliance scores of the plurality of standardized custom template trees and remove all but the standardized custom template tree with the lowest compliance score among the plurality of standardized custom template trees.

[0030] At this time, the processor can calculate the compliance score using the following <Mathematical Formula 1>.

[0031] [Mathematical Formula 1]

[0032]

[0033] Here, CMS() is the compliance score and AAST i is the ith standard template, TED() is the tree edit distance indicating how much the standard template tree has changed, and SMT ij is the jth submodel template included in the ith standard template.

[0034] At this time, the processor can calculate the bit vector distance between the customized templates by performing an exclusive OR on the bit vectors and adding the bit values ​​to the bit vectors.

[0035] The present invention relates to a device and method for generating a common asset management shell template, which implements a company's customized template in the form of a standard template and clusters similar templates to generate a common asset management shell template, thereby enabling efficient management of a company's assets.

Unless otherwise stated, the descriptions given in one embodiment may also apply to other embodiments, and detailed descriptions will be omitted to the extent of overlap.

[0053] Hereinafter, a device and method for generating a common asset management shell template according to an embodiment of the present invention will be described in detail with reference to the attached FIGS. 1 to 11.

[0054] FIG. 1 is a flowchart illustrating a process for creating a common asset management shell template according to one embodiment of the present invention.

[0055] Referring to FIG. 1, the method of the present invention can receive standard templates and customized templates (110).

[0056] And, the method of the present invention can convert each of the standard templates and the custom templates into a tree form (120).

[0057] In step 120, the method of the present invention can convert each of the standard templates and the custom templates into a tree form, and convert them into a sorted tree form. That is, for example, the tree's attributes can be organized by sorting them in alphabetical order.

[0058] In addition, the method of the present invention can generate a standardized custom template tree by changing each of the custom template trees into the form of a standard template tree (130).

[0059] In step 130, the method of the present invention can generate a standardized custom template tree by changing each of the custom template trees into the form of a standard template tree by deleting an attribute from the standard template tree, adding an attribute to the standard template tree, and changing an attribute included in the standard template tree.

[0060] And, the method of the present invention can generate a master template including all standardized custom template trees (140).

[0061] In step 140, the method of the present invention can generate a master template by sorting the standardized custom template tree in descending order of depth to the leaf node, and if the depth to the leaf node is the same, sorting it in alphabetical order and combining them.

[0062] And, the method of the present invention can assign a bit vector index to a leaf node included in a master template and assign a bit value (150).

[0063] And, the method of the present invention can check the bit vector of each customized template (160).

[0064] And, the method of the present invention can calculate the bit vector distance between the customized templates by using the bit vector of each of the customized templates (170).

[0065] In step 130, the method of the present invention can calculate the bit vector distance by performing an exclusive OR on the bit vectors between the customized templates and adding the bit values ​​to the bit vectors.

[0066] In addition, the method of the present invention can cluster customized templates based on bit vector distances between customized templates to generate a common asset management shell template (180).

[0067] At step 180, clustering can utilize K-Means Clustering. That is, K-Means Clustering is a clustering technique that attempts to form K user-specified clusters, repeatedly optimizing clusters by minimizing the distance between the center of each cluster and the bit vector, and then converges.

[0068]

[0069] FIG. 2 is a flowchart illustrating a process for determining a standardized custom template using a compliance score according to one embodiment of the present invention.

[0070] Referring to FIG. 2, the method of the present invention can check whether each of the customized template trees has been changed into a standard template tree, and whether a plurality of standardized customized template trees have been changed among the customized template trees (210).

[0071] If, as a result of the verification in step 210, there exists a custom template tree that has been changed into multiple standardized custom template trees, the method of the present invention can calculate a compliance score of the multiple standardized custom template trees (220).

[0072] Compliance scores at step 220 can be calculated using the following <Mathematical Formula 1>.

[0073] [Mathematical Formula 1]

[0074]

[0075] Here, CMS() is the compliance score and AAST i is the ith standard template, TED() is the tree edit distance indicating how much the standard template tree has changed, and SMT ijis the jth submodel template included in the ith standard template.

[0076] A lower compliance score indicates fewer changes from the standard template.

[0077] Therefore, the method of the present invention can remove only the standardized custom template tree with the lowest compliance score from among a plurality of standardized custom template trees (230).

[0078]
