Description

Method for building a maintenance repair operating (MRO) data base (DB) and Method for numbering a MRO administrator number using approximately}

The present invention relates to a method for constructing a material information database and a method for assigning a material management number using the same, and in particular, a core word, a subject element, and an identification factor representing a common name, a characteristic, and a specification of a material for easy database construction and material management. And a method of assigning a material information database using the same as a material control number and using it as a material control number and a material control number assignment method using the same.

Maintenance Repair Operating (MRO) is a consumable material used by businesses. It encompasses simple office supplies such as ballpoint pens and copy paper in various office automation equipment. Since the above materials have already secured credit, most of the products are often known. The domestic MRO market is growing in size, and MRO is regarded as the best product for Internet e-commerce. Through such auctions, reverse auctions, bidding, and joint purchases through the Internet e-commerce, it is possible to reduce the cost of MRO materials to buyers and provide a smooth seller to sellers, which can be beneficial to all participating companies. With this system, buyers can free themselves from inventory burdens and significantly reduce the labor costs of purchasing departments. In addition to reducing marketing costs, suppliers can make long-term plans to ensure stable production.

The MRO database has such advantages, but the materials are managed by each company participating in the MRO business. In addition, by considering the number of item types in the MRO's database, the company's own uniform code is assigned and managed, which not only puts a lot of load on the database but also makes it possible to exchange the database with other companies. It is impossible, and each company performs redundant work due to the database and wastes time and manpower.

Accordingly, an object of the present invention is to assign a code of a material, a central word, a subject element, and an identifying factor indicating the common name, characteristics, and specifications of a material, for the purpose of unifying part numbers for materials, establishing a database for materials, and facilitating material management. At the same time, it provides a material information database construction method using this as a material control number and a material control number assignment method using the same.

In addition, another object of the present invention is to publicize the material information database on the Internet, and not only to disclose the material information database and electronic commerce, but also to manage various kinds of human resources, funds, etc. for all parts of the company such as production, sales, human resources, and accounting. It is to provide integrated solution of corporate and national management by integrating and managing resources as a system.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

EXAMPLE

First, terms to be described below are defined.

1. Material classification database group group: Means a broad group of database groups to which the material belongs by applying criteria classified by KS (Korean Industrial Standards), HS, government agencies (Public Procurement Service), and various authorized analysis agencies. For example, ① raw materials, ② machinery and equipment materials, ③ metal materials, ④ electrical and communication materials, ⑤ facility materials, ⑥ daily necessities materials, ⑦ chemical materials, ⑧ machine tool materials, ⑨ information industry materials, and ⑩ work and repair · Construction materials ··· etc. can be divided into.

2. Item classification database group group: A subgroup of the material classification database group group, which is the most basic word among the item name classification criteria of the material, and is a database group group classified based on the item-centered word of a higher concept for the item name. it means. For example, the above-mentioned ② machine and equipment materials can be classified into a roller, a valve, a bearing, a valve, a rack, a chain, a filter, a hose, and a heater.

3. Item classification database group group: A subgroup of the item classification database group group, which is a word of a specific item name center word for the item, and means a database group group classified based on a subject element for the item name center word. For example, ② for the belt belts of machinery and equipment materials, it can be divided into V-belt, 드 less belt, ㉢ Siegling belt, ㉣ belt, ㉤Zi belt, ㉥ ameral belt, ㉦ polymax belt. Can be. In this case, in the case of the belt belt, the main element is composed of a first main element and a second main element, and specifically, the first main element includes a dimension and a second main element is a reference number.

4. Part number classification database group group: means a group of database groups in which identification factors for each subject element of the item names are organized into tables and assigned codes corresponding to the identification factors to materials. It includes all the basic elements of the material classification, item classification, and product classification database.

Here, the terms of the item-centered words, the item-name center words, the subject elements, and the identifying factors will be described in detail.

a. Item-centered word: Refers to the general name of things that people can understand most easily about materials. The item classification database group group may be referred to as a name.

b. Product name center word: It means the specific name for the material. It may be referred to as a name for distinguishing the product name classification database group group.

c. Subject element: An element that distinguishes the characteristics of the material. That is, it can be defined as a term that selects only features that can be easily associated with materials. This subject element should only define non-overlapping features that distinguish other materials.

Ex) horizontal, vertical, height, shape, purity, form, voltage, ...

d. Identifier: A standard that specifically classifies a subject element that distinguishes the characteristics of the material, and the code length of the identifier is also determined by the type of the classified standard. In the case of the belt belt, for example, the dimension of the first main element and the identification number of the second main element may be represented as shown in Table 1 below. Table 1 shows some of the code parts but not the whole.

TABLE 1

code size code Identification Number 01 A type 0020 20 (508mm) 02 Type B 0021 No. 21 (533 mm) 03 C type 0022 No. 22 (559 mm) 04 D type 0023 No. 23 (584 mm) 05 E type 0024 No. 24 (610 mm) 06 M type 0025 25 (635mm) 0026 No. 26 (660 mm)

1 is a view conceptually showing the structure of a database according to an embodiment of the present invention. Referring to FIG. 1, the database structure of the present invention forms the item classification database group group 100 as a material classification database group group 100 and a subgroup of the material classification database group group 100. The item classification database group group 300 is formed as a subgroup in each of the item classification database group groups 200, and the item classification database 400 as a subgroup in each of the item classification database group groups 300 is provided. It is forming.

The material classification database group group 100 classifies the database to which the material belongs by applying the criteria classified by Korean Industrial Standards (KS), HS, FAS, JIS, price information, distribution prices, PPS, government agencies and have. In this embodiment, materials are classified into ① raw materials ② machinery and equipment materials ③ metal materials ④ electrical and communication materials ⑤ facility materials ⑥ daily necessities materials ⑦ chemical materials ⑧ machine tool materials ⑨ information industry materials ⑩ work, repair and construction materials. Of course, in the classification of the material, it is presented only as an embodiment of the classification criteria, not presented in an absolute concept. The material classification database group group 100 is assigned a material code in consideration of the possibility of being classified later. In this embodiment, one material code is used, and a material code of "B" is assigned to the machine and equipment materials. This can also be seen through the program window shown in FIG. 2A. 2A to 2R are diagrams illustrating a program window for performing a search and numbering process of a built database. Specifically, FIG. 2A shows a program window for performing code management of a material classification database group group. 2b to 2d are diagrams showing material classification statuses. Item classification database group group is formed in each material classification database group group as a subgroup, and item classification database group group is also formed in the item classification database group group as a subgroup.

The item classification database group group 200 stores an item-centered word having a higher concept, which is the most basic among the classification criteria of the corresponding product name. An item-centered word database 210 for separately storing the item-centered words of this higher concept is prepared separately. Specifically, the item-centered keyword may be, for example, a? Roller, a? Valve,? A bearing,? A belt,? A lathe,? A chain, a? Filter, a? Hose, a? Heater, and the like for the machine and equipment materials. The item classification database group group 200 is given an item code in consideration of the possibility to be classified later, in the present embodiment consists of a single item code, the item code "A" to give the belt have. As a result, ② the belts have the code “BA” for machine and equipment materials. In addition, the item-centered word database is linked to the alias item-centered word database 220. This is to unify the item-centered words, which can be input differently considering the state that the concept of the item-centered words does not match one. This can also be seen through the program window shown in FIG. 2E. Specifically, FIG. 2E shows a program window for performing code management of the item classification database group group. 2F to 2H are diagrams showing the item status. In each item classification database group group, it can be seen that the item name database group group is formed as a subgroup.

The product name classification database group group 300 specifically classifies the product names corresponding to the item, and consists of specific product name center words for the item center word. A product name center database 310 for storing the product name center word separately is provided. In addition, the product-name core words have a subject element that distinguishes the characteristics of the material and are classified based on this. A subject element database 320 for separately storing the subject element is provided. Here, an alias product name center database (not shown) in which the aliases for the product name core words are separately databased, and an alias subject element database (not shown) in which the aliases for the subject elements are separately databased are provided. For example, when the registered product name center word is "V belt", "V belt", "V Belt", "V belt", "bu belt", etc. are registered as alias name item center words. In addition, when the registered core word is "TV", "TV", "TV", "Television", etc. are registered as the alias product name center words.

The above product name is, for example, (2) for a belt of machine and equipment materials, such as a belt belt, a beltless belt, a belt belt, a belt belt, a belt belt, a belt belt, a belt belt. It can be divided into The product name code is assigned to the product name classification database group group in consideration of the possibility of being classified later. In the present embodiment, two product name codes are assigned, and a product name code of "01" is assigned to the VW belt. . Because of this, the valve belt has code “BA01” for the belt belt of machinery and equipment materials.

In this case, in the case of the belt belt, the main element is composed of a first main element and a second main element, and specifically, the first main element includes a dimension and a second main element is a reference number. Each of these subject elements has a separate identifier database (not shown) that specifically classifies them. Each identification factor has identification factor codes that distinguish them, and the number of codes is given in consideration of the possibility that this identification factor can be classified. The above-mentioned dimensions give the number of identification factor codes of two digits, and the identification number gives the number of identification factor codes of four digits. For example, if the valve is B type 25 of the belt, it will have the code "BA01020025". This code corresponds to the article number described later.

This can also be seen through the program window shown in FIG. 2I. FIG. 2I shows a program window in which item name management is being performed, and FIG. 2J shows a program window in which identifier management for the item name is being performed. In addition, Figures 2k to 2l is a view showing the product name status. The program window showing the status of the product name displays the product name, the subject element, the code length, and the like. In addition, a search word input window is provided in the program window showing the product name status so that a search word can be searched by inputting a search word.

2M and 2N show a program window to give an article number as one of the features of the present invention. Figure 2m is to prepare and configure the identification factor for each subject element to select the identification factor of the subject element for the item name, forming the part number generation key in the program window to generate the product number by selecting the identification factor corresponding to the material I'm making it. Selecting an identification factor corresponding to the material and pressing the part number generation key generates the part number as shown in FIG. 2N.

The article number classification database group group is assigned to the article number for the material and stored by classifying it by product name, article number, standard and unit, and is provided to provide a separate electronic catalog database 410 to provide an image. 2O to 2R are program windows showing an item number inquiry and an item number status. As shown in Figure 2o and 2p, during the article number search, you can input the article number, article name, standard, unit, etc. through the search word input window, it is also possible to output an image for the article number selected from the output output through the search. have. In addition, as shown in Figures 2q to 2r, it can be seen that each article number status is databased with the image.

These databases are basically configured to output the items, item names, item numbers, etc. associated with the core words, subject elements and identifiers by executing mapping to the core words, subject elements and identifiers. This may be performed by the above mapping process, or by receiving a specific code when stored in a database, executing a specific execution code associated with the specific code, and searching for a corresponding address to output specific data associated with it. It may be.

Let's take a look at the construction process of the database configured as described above and the part numbering method using the same.

3 is a flowchart illustrating an item numbering process and a database construction process according to an embodiment of the present invention.

Prior to the description of the drawings, it is assumed that both the user who builds the database for any material or the user who searches for the material before the present process has general knowledge, and the database construction and search is started through the product name core word. That is, the present embodiment will be described from the process of building and searching the database through the product name core word.

In addition, the database does not exist at all, but the database has already been established to some extent by applying the criteria classified by KS, HS, FAS, JIS, price information, distribution price, PPS, and government agencies. Assume that the construction of

Referring to the above assumptions, as shown in FIG. 3, when data on materials is first collected (S100), a search is performed by inputting a product name center word (S200). Thereafter, the product name classification database group group is searched to determine whether there is an item name that matches the product name center word (S300). As a result of determining whether there is a product name center word, a subject element related to the central word is output (S400). At this time, it is determined whether the output subject element is an element for distinguishing the characteristics of the material (S500). As a result of the subject element determination, if it is determined that the subject element is an accurate element for distinguishing the characteristics of the material, an identification factor for each subject element is output (S600). Then, it is determined whether there is an identification factor for each subject element (S700). If it is determined that there is an identification factor for each subject element, the identification number is selected from the identification factor and an item number is assigned (S800).

On the other hand, in step S300, if it is determined that there is no name-centered word, as a result of determining whether there is no name-centered word, the search is performed by inputting an item-centered word which is a higher concept of the name-centered word (S310). The item classification database group group is searched to determine whether there is an item-centered word (S320). The reason for searching for the item-centered word of higher concept for the item-named key word is that the items of the material to be searched may be classified into other items. At this time, if it is determined that there is an item-centered word, as a result of the item-centered word search, the process after step S400 for outputting the item-named center word of the subgroup related to the item-centered word and its subject element is performed.

Here, in step S320, if it is determined that there is no item-centered word search result, the search is performed by inputting an alias (another name) of the item-centered word (S330). In this case, it is determined whether there is an alias by searching an alias item center word database associated with an alias of the item center word (S340). In step S310, if it is determined that there is an alias, the item item center word of the alias is output, that is, the registered item center word is output to the user, and the item item center word of a higher concept is input and searched by inputting the item item center word. Proceed to On the other hand, if it is determined that there is no alias in the step S340, the corresponding item-centered word is newly registered (S350). In addition, the product name center word and its subject elements are determined (S360), and identification factors for each subject element are also prepared and newly registered (S370). After that, the process returns to step S200 to perform the search again.

On the other hand, if it is determined in step S500 that the subject element is not the correct element to distinguish the features of the material, the alias of the subject element is input and searched for (S510). At this time, it is determined whether the subject element is aliased (S520). If it is determined that there is an alias for the subject element, the alias subject element database is searched and the correct original subject element corresponding to the subject element, that is, the registered subject element is output. (S530). At this time, if it is determined that there is no alias in step S520, if there is no alias, a subject element for the corresponding product name is registered (S540), and an identifier for each subject element is also registered (S550). After that, the process returns to step S200 to perform the search again.

On the other hand, if it is determined in step S700 that there is no identification factor corresponding to the material in the identification factor for each subject element, it is determined whether the standard is registered in an authorized institution (S710). At this time, if it is determined that it is not registered in an authorized institution, it performs a defect processing for the material (S710), and if registered in the authorized institution registers a new identifier (S720), and outputs the identifier for each subject element Proceed to step S600.
