Description

Rebar's e-commerce system {ELECTRONIC COMMERCE SYSTEM OF REBAR}

The present invention relates to an e-commerce system for rebar.

Rebar is a mechanical structure that is used very importantly in civil engineering and construction fields as a construction material mainly manufactured from carbon steel.

According to the KS regulations currently in use in Korea, general standards for reinforcing bars are D10, D13, D16, D19, D22, D25, D29, D32, and other special standards include D35, D38, D41, D43, D51, and D57. Here, D means the diameter.

Until now, the purchase of these various reinforcing bars has been implemented offline and has the following problems because it is structured as a system for the convenience of the seller.

The seller can be largely divided into imported rebar sellers and domestic rebar sellers, and the rebar sellers can also be roughly divided into producers and wholesalers. From the seller's point of view, since most of the rebar sales are performed in large quantities, there is a problem in that inventory is inevitably generated according to the remaining quantity, and it is impossible to accurately identify the inventory.

Therefore, in order to purchase a specific rebar, the buyer has no choice but to place an order after checking whether the rebar is in stock by phone or e-mail to the seller one by one, and there are many restrictions in purchasing a small amount of rebar. .

In addition, the purchase cost may be the sum of the price of the rebar and the transportation cost. Here, there is a problem in that e-commerce cannot be activated because the transportation cost occupies a large proportion due to the nature of the rebar purchase.

Specifically, since the buyer cannot comprehensively and quickly grasp the above transportation cost, that is, the transport rate by location or the tolerance fee according to the amount of rebar purchase, it is necessary to purchase rebar from a certain seller to accurately calculate the minimum cost for rational rebar purchase. It is difficult to determine whether this is the case.

In addition, due to the nature of the scale of rebar products, medium-to-large-scale purchases have been made through existing offline companies, not small ones, and accordingly, there were many difficulties and limitations in purchasing rebar products by small companies or individual operators.

Therefore, the problem of supply and demand and purchase unit price of rebar, which accounts for the largest proportion of construction materials currently used in buildings, requires a more difficult and difficult purchase process for smaller companies.

In other words, under the current transaction situation, it is not only difficult to supply and supply rebar products to small businesses or individual business owners, but even if they do, medium and large companies have no choice but to make high-priced purchases in a reverse-discriminatory manner, while receiving discounts according to the quantity purchased. have.

Compared to medium and large companies that purchase through steelmakers or primary distributors, which benefit from reduced purchase stages, priority allocation of supply and demand, and unit price discounts, small or individual business owners often have to purchase through several stages and purchase accordingly. unit price will rise.

The payment conditions for purchase are also in most cases where small-scale companies have no choice but to purchase with advance payment or immediate cash price.

The present invention has been devised to solve the above problems, and an object of the present invention is to provide the ease of inventory grasp and disposal from the seller's point of view, and the minimum cost for the purchase of rebar from the buyer's point of view. An object of the present invention is to provide an e-commerce system of rebar that can purchase quickly and accurately, and thus establish a sound commercial order.

Another object of the present invention is to provide an e-commerce system for rebar that enables pre-order (reflection of production) or small order of rebar that meets the needs of buyers.

In order to achieve the above object, the present invention provides at least two or more supplier terminals for providing reinforcing bar information including the type of rebar possessed, the price per type, the quantity per type, and the address of the store; at least one buyer terminal providing purchase information including a type of rebar to be purchased, a quantity by type, and an address of a drop-off point; The total purchase amount obtained by adding the rebar information input from the supplier terminal and the purchase information requested from the purchaser terminal to each of the supplier terminal and the buyer terminal connected to the network, and the transportation cost from the loading point to the disembarkation point. a server that calculates each; and a seller terminal connected to the server in a network to manage the server; provides an e-commerce system of rebar including.

In addition, the server, the reinforcing bar information input from each of the provider terminals is stored or changed, respectively, the rebar database; a transportation cost database in which information on transportation cost per weight of rebar determined by region and region from loading station to unloading station is stored or changed for each type of truck; and a price calculation unit for calculating the total purchase amount by using the information of the reinforcing bar database and the information of the transportation cost database according to the purchase information requested from the purchaser terminal.

In addition, when there is at least one supplier that simultaneously satisfies the type and quantity of rebar requested to be purchased, the price calculation unit selects a supplier that simultaneously satisfies the quantity and type of rebar requested to be purchased from the rebar database, and By calculating the transportation cost from the loading point of each supplier to the unloading location input by the buyer from the transportation cost database, the rebar purchase cost and the transportation cost are added up for each supplier to generate the total purchase amount in the order of lowest price or fastest delivery.

In addition, if there is no supplier that simultaneously satisfies the type and quantity of rebar requested to be purchased, but there is at least one supplier that satisfies the type or quantity of rebar requested to be purchased, the price calculation unit makes a purchase request from the rebar database Select a supplier that satisfies the type or quantity of rebar, and calculate the transportation cost from the loading location of each selected supplier to the unloading location entered by the purchaser via the loading station of another supplier from the transportation cost database. , the total purchase amount information can be generated in the order of lowest price or fastest delivery by adding up the rebar purchase cost and transportation cost for each case.

In addition, the reinforcing bar information provided from the supplier terminal and stored or changed in the reinforcing bar database may further include a type of rebar to be produced or stocked, a quantity for each type, and a scheduled production or stocking date.

In addition, if there is no supplier that satisfies the type and quantity of rebar requested to be purchased, either at the same time or separately, the price calculation unit is from the reinforcing bar database among suppliers who have entered the type of rebar to be produced or stocked, the quantity for each type, and the expected production or storage date. A supplier that satisfies the quantity and type of rebar requested to be purchased is selected, and the transportation cost from the loading point of each selected supplier to the unloading location input by the buyer is calculated from the transportation cost database, and the rebar purchase cost and transportation cost are calculated by each supplier They can be summed to create a total purchase in order of lowest price or fastest delivery.

In addition, the server transmits whether or not the provided rebar information is received, purchase information, purchase confirmation, pre-order purchase information, or whether stock is insufficient, to the seller's terminal, or whether purchase information is received, rebar information, and the price calculation unit calculates It may further include an information transmitter that transmits the total purchase amount and the expected delivery date to the terminal of the purchaser.

In addition, when there is no supplier that simultaneously or respectively satisfies the type and quantity of reinforcing bars requested to be purchased, the information transmitter may transmit pre-order purchase information to the supplier terminal.

In addition, the server may further include a member information database in which member information including the names, addresses, and account numbers of the supplier and the purchaser is stored.

In addition, the server may further include an electronic payment unit that transfers all or part of the amount paid from the purchaser terminal to the account of the seller.

The present invention can provide the ease of inventory grasp and disposal from the seller's point of view through the server's reinforcing bar database and information sending unit.

In addition, through the price calculation unit and the information transmission unit of the server of the present invention, the minimum cost for the purchase of reinforcing bars is provided from the point of view of the purchaser and can be purchased quickly and economically.

In addition, the present invention can provide a rebar e-commerce system that can establish a sound commerce order by enabling pre-orders or small orders for rebars that meet the needs of buyers by effectively connecting the seller and the buyer as described above.

In addition, the present invention can significantly reduce the problems of the purchase procedure and cost, secure transaction stability, simplify the procedure, make the payment system transparent, diversify product selection, and most importantly, stabilize the supply and demand of rebar, so small and medium-sized enterprises Or, it can be said that it is a system that is absolutely necessary for individual business owners.

Unless otherwise specified, all terms herein have the same general meaning as understood by those skilled in the art, and if a term used in this specification conflicts with the general meaning of the term, the definition used herein shall govern.

However, the invention to be described below is only for explaining the embodiments of the present invention, not for limiting the scope of the present invention, and the same reference numbers used throughout the specification indicate the same components.

1 is a conceptual diagram illustrating an e-commerce system of reinforcing bars according to an embodiment of the present invention.

Referring to FIG. 1 , the rebar e-commerce system according to an embodiment of the present invention may largely include a provider terminal 100 , a purchaser terminal 200 , a server 300 , and a seller terminal 400 .

Here, the terminal refers to a personal computer (PC), a cellular phone, a PCS phone (Personal Communication Service phone), a personal digital assistant (PDA; Personal Digital Assistant), a WAP phone; It may be a Wireless Application Protocao phone, a smart phone, or a tablet, but is not limited thereto.

The provider terminal 100 may provide reinforcing bar information including the type of rebar possessed, the price for each type, the quantity per type, and the address of the location of the reinforcing bar.

Here, the price for each type of reinforcing bar provided by the supplier may be different from the price of the reinforcing bar purchased by the buyer, which will be described later. That is, the seller, which will be described later, may calculate the rebar purchase cost that can be provided to the buyer by adding a predetermined fee to the price of the rebar provided by the supplier.

Such a supplier terminal 100 is provided for each supplier, and preferably two or more (two suppliers or more) may be provided for searching and selecting purchase information to be described later.

In addition, the reinforcing bar information that is provided from the provider terminal 100 and can be stored or changed in the rebar database 311 of the server 300 to be described later is the type of rebar to be produced or stocked, the quantity and expected production date of each type, the expected stocking date or It may further include a holiday, and may further include the type of reinforcing bar (pre-order) that can be produced to order.

The purchaser terminal 200 may provide purchase information including the type of rebar to be purchased, the quantity for each type, and an address of a disembarkation point.

Such purchaser terminals 200 are provided for each purchaser, and at least one or more may be provided.

In addition, the purchaser terminal 200 may selectively add or exclude a desired delivery date when providing the purchase information.

The seller terminal 400 is connected to the server 300 and the network 10 to manage the server 300 , and generates algorithms and programs that can be included in the control unit 320 of the server 300 to be described later. . Correction or deletion may be performed, or information that may be included in the database unit 310 to be described later may be created, corrected, or deleted.

For example, the seller may add a supplier-only program provided to the supplier terminal 100 or a buyer-only program provided to the buyer terminal 200 to the server 300 through the seller terminal 400 . .

The server 300 is connected to the network 10 with the provider terminal 100 and the purchaser terminal 200, respectively, and as the reinforcing bar information input from the provider terminal 100 and the purchase information requested from the purchaser terminal 200 It is possible to calculate the total purchase amount by adding up the rebar purchase cost for each supplier requested to be purchased and the transportation cost from the loading point to the unloading location.

As described above, the rebar purchase fee provided to the buyer may include the seller's fee.

Here, the network 10 refers to 5 ^th generation (5G), Bluetooth, long term evolution-advanced (LTE-A), long term evolution (LTE), wireless fidelity (Wi-Fi), NFC, Zigbee, Z- It may refer to a communication method such as wave or IrDA, but is not limited thereto.

The server 300 may largely include a database unit 310 and a control unit 320 , and the database unit 310 and the control unit 320 may perform functions by interworking with each other.

The database unit 310 includes a reinforcing bar database 311 in which reinforcing bar information input from each of the supplier terminals 100 is stored or changed, respectively, and the transportation cost per weight of rebar determined from the loading point to the discharging point by region and region. The information may include a transportation cost database 312 that is stored or changed for each type of freight vehicle.

In addition, the database unit 310 may further include a member information database 313 in which member information including names, addresses, and account numbers of suppliers and purchasers or business registration certificates is stored. Here, the address of the supplier may be different from the address of the reinforcing bar information provided by the supplier.

The control unit 320 includes a price calculation unit 321 that calculates the total purchase amount based on the information of the reinforcing bar database 311 and the information of the transportation cost database 312 according to the purchase information requested from the purchaser terminal 200. can

Under the rebar e-commerce system according to the embodiment of the present invention by the price calculation unit 321, a buyer can quickly and economically purchase rebar, which will be described in detail below.

The total purchase amount of rebar is the sum of the rebar purchase cost, which is the total price of rebar the buyer wants, and the transportation cost of shipping the rebar from the loading station to the unloading location.

Unlike other e-commerce systems including other courier services, in the case of rebar, the transportation cost caused by the weight of rebar accounts for a large portion of the total purchase amount.

Here, the transportation cost may be set as an amount obtained by multiplying the weight of the reinforcing bar by the transportation rate set for each region and region from a specific location.

For example, if the transport rate per ton (t) from the loading station A to the unloading station B is 12,000 won, if 26 tons of rebar is purchased, the transportation cost is 312,000 won.

However, the following variables should be taken into account for these transport costs.

First of all, the transportation cost may vary depending on the location of the location, and this may be determined depending on the accessibility of the location even in the same area.

In addition, transportation costs may vary depending on whether there is an empty freight charge.

For example, if you use a 26-ton truck with a transport rate of 12,000 won per ton (t) to transport 16 tons of rebar you want to purchase, you will incur an empty freight charge of 120000 won for 10 tons.

Also, transportation costs may vary depending on vehicle selection.

For example, to purchase 5 tons of rebar, there is no need to use a 26-ton freight vehicle. However, if the length of rebar you want to purchase exceeds the loading length of a 5-ton freight vehicle, select a large freight vehicle regardless of the maximum loading capacity. There is a problem that must be done.

In addition, the transportation cost may vary when purchasing a single rebar or different types of reinforcing bars from one storehouse, or purchasing a single rebar or different kinds of rebars from two or more storehouses.

For example, if you want to purchase different types of reinforcing bars at one location, transporting each type of rebar with a different truck may result in excessive transportation costs. It can be delivered with one suitable truck. This is generally referred to as mixed loading, and the purpose of mixed loading is to reduce or eliminate empty freight charges.

For another example, if the demand for reinforcing bars to be purchased cannot be met at a single loading station, it may be loaded via each loading station rather than being delivered separately from two or more loading stations. This is generally referred to as mobile loading (mobile lorry), and in the case of such mobile loading (dual lorry), the cost of mobile loading (dual lorry) is added, but it may be more economical to reduce or eliminate the tolerance freight cost.

As described above, the price calculation unit 321 according to the present invention can calculate the most economical total purchase amount by comparing the economical calculation of transportation cost and the price of reinforcing bars for each supplier or provide information for fast delivery to the buyer. .

First, if there is at least one supplier who simultaneously satisfies the type and quantity of reinforcing bars requested to be purchased, it is as follows.

The price calculation unit 321 selects a supplier that simultaneously satisfies the quantity and type of rebar requested to be purchased from the reinforcing bar database 311, and transport costs from the loading point of each selected supplier to the unloading point input by the buyer. may be provided from the transportation cost database 312 and calculated, and the total purchase amount may be generated in the order of lowest price or fastest delivery by adding up the rebar purchase cost and transportation cost for each supplier.

The first case is a situation in which moving loading is unnecessary, and the price calculation unit 321 adds up the rebar purchase cost according to the rebar supply price for each supplier and the transportation cost for each supplier, respectively, and calculates information in the order of lowest price or fastest delivery. can be sorted.

For example, if the buyer wants to purchase x reinforcing bars A and y rebar B, he inputs the type and quantity of rebars through the purchaser terminal 200, and purchases the desired delivery date, lowest price, fastest delivery, or other purchases. You can enter your request.

After that, according to this purchase information, the price calculation unit 321 searches for a supplier that simultaneously satisfies the quantity and type of rebar requested to be purchased from the reinforcing bar database 311, and provides each of the satisfied suppliers A and B. After calculating and sorting each total purchase cost, the server 300 may provide the information to the purchaser terminal 200 .

Second, if there is no supplier satisfying the type and quantity of rebar requested to be purchased, but there is at least one supplier each satisfying the type or quantity of rebar requested to be purchased, as follows.

The price calculation unit 321 selects a supplier that satisfies the type or quantity of the reinforcing bar requested to be purchased from the reinforcing bar database 311, and selects a supplier from each of the selected suppliers via the store occupancy of another supplier. The total purchase amount information can be generated in the order of lowest price or fastest delivery by calculating the transportation cost to the destination entered by the buyer from the transportation cost database 312, adding up the rebar purchase cost and the transportation cost for each case.

In the second case above, mobile loading (double loading) is required, and the price calculation unit 321 calculates the rebar purchase cost according to the rebar supply price for each supplier and the mobile loading (dual loading) cost for each supplier. You can sort the calculation information in the order of lowest price or fastest delivery by summing up the included shipping cost for each case.

For example, if the buyer wants to purchase x reinforcing bars A and y rebar B, he inputs the type and quantity of rebars through the purchaser terminal 200, and purchases the desired delivery date, lowest price, fastest delivery, or other purchases. You can enter your request.

Thereafter, according to the purchase information, the price calculation unit 321 searches the reinforcing bar database 311 to see if there is a supplier that simultaneously satisfies the quantity and type of rebar requested to be purchased, and a supplier that satisfies all of the purchase information. 1) Supplier A with xa A rebar, 2) Supplier B with y rebar B, 3) Supplier Jeong with more than a A rebar, 4) Supplier A with x rebar After calculating the most economical total purchase amount or arranging the bottles in the order of fastest delivery, the server 300 may provide the bottles to the purchaser terminal 200 .

Third, if there is no supplier that satisfies the type and quantity of rebar requested for purchase at the same time or separately, it is as follows.

The price calculation unit 321 has no suppliers satisfying the current purchase request from the reinforcing bar database 311, but the type of rebar to be produced or stocked, the quantity for each type, and the reinforcing bar requested to be purchased from among the suppliers who have entered the expected production or stock date. A supplier is selected that simultaneously satisfies the quantity and type of You can generate total purchases in order of lowest price or fastest delivery.

For example, if the buyer wants to purchase x rebar A and y rebar B, he inputs the type and quantity of the rebar through the purchaser terminal 200, and purchases the desired delivery date, lowest price, fastest delivery, or other purchases. You can enter your request.

After that, according to this purchase information, the price calculation unit 321 searches for a supplier that simultaneously satisfies the quantity and type of rebar requested to be purchased from the reinforcing bar database 311, and the supplier satisfying the purchase information is However, 1) Supplier A, who is planning to produce or receive more than x A rebar, 2) Supplier B, who is scheduled to produce or receive y or more B rebar, 3) Supplier Jeong, who has xa A rebar, 4) A rebar A After calculating the most economical total purchase amount or arranging in the order of fastest delivery during mobile loading (dual loading) for the supplier information you have, the server 300 may provide it to the purchaser terminal 200 .

The third case is a case in which some or all of the reinforcing bars in the purchase information are insufficient in the market. You can sort the output information in order.

In addition, the server 300 transmits whether the provided reinforcing bar information is received, purchase information, purchase confirmation, pre-order purchase information, or stock shortage to the supplier's terminal, or whether purchase information is received, rebar information, and the price calculation. It may further include an information transmitting unit 323 for transmitting the total purchase amount calculated in the unit 321 and the expected delivery date to the terminal of the purchaser.

By the information sending unit 323, the supplier can grasp the stock with the supplier terminal 100, and accordingly, the rebar information change for production control of rebar, stocking amount control or inventory exhaustion to the server 300 can provide

In addition, by the information transmitting unit 323, the purchaser can purchase the rebar to be purchased most economically or can be delivered quickly, and can effectively purchase the rebar without having to figure out the fluctuating transportation cost or rebar price by himself/herself.

In addition, as in the third example, when there is no supplier that simultaneously or respectively satisfies the type and quantity of reinforcing bars requested to be purchased, the information transmitting unit 323 transmits the information received from the purchaser terminal 200 to the supplier terminal 100 . Pre-order purchase information with purchase information as the purchase request content may be transmitted.

In addition, the server 300 may further include an electronic payment unit 322 that transfers all or part of the amount paid from the purchaser terminal 200 to the seller's account, thereby providing the purchaser with purchase information. At the same time, it can be promoted to conclude a quick transaction.

2 is a conceptual diagram illustrating an exchange between a buyer and a supplier or a buyer.

According to the reinforcing bar e-commerce system according to the embodiment of the present invention as described above, the present invention provides a supplier with an opportunity to quickly sell reinforcing bars, and provides sales information that enables buyers to purchase desired rebars economically. It can provide benefits to both parties.

In addition, since the seller can provide the buyer with reinforcing bar information from a number of suppliers, it can help to establish a sound commercial order.

In addition, since the seller can receive a fee for using the reinforcing bar e-commerce system of the present invention or a service fee from the buyer, it is possible to create a maintenance cost of the server 300 or a new profit structure.

First, the user can access the server 300 (S10).

Thereafter, the server 300 may check whether the user who has accessed through the member information database 313 is a member (S20).

If you are not a member, you can recommend membership registration (S21), and if you are a member, it is determined whether you are a supplier or a buyer (S30).

In the case of a supplier, after receiving the reinforcing bar information from the supplier terminal 100 described above (S31), determining whether there is a change in the reinforcing bar information (S32), and until there is a purchase by the buyer, the server 300 stores the reinforcing bar database ( 311) stores the reinforcing bar information (S33).

If the supplier is not the supplier, it is determined whether the supplier is a buyer (S40).

If neither a supplier nor a buyer, membership registration may be recommended (S21), and in the case of a buyer, purchase information is received (S41).

After that, the server 300 has the reinforcing bar information of each supplier stored in the reinforcing bar database 311 and calculates the total purchase amount satisfying the purchase information through the price calculation unit 321 (S42), the purchaser terminal The total purchase amount may be sent to ( 200 ) in the order of lowest price or fastest delivery ( S43 ).

Thereafter, upon receipt of a purchase payment from the purchaser terminal 200, trading information is transmitted to each supplier, seller, or purchaser (S50).

In short, the present invention can provide the ease of inventory grasp and disposal from the point of view of the supplier through the reinforcing bar database 311 and the information transmitter 323 of the server 300 .

In addition, through the price calculation unit 321 and the information transmission unit 323 of the server 300 of the present invention, the minimum cost for the purchase of the rebar is provided from the point of view of the purchaser, so that it can be purchased quickly and economically.

In addition, the present invention can provide an e-commerce system for rebar that can establish a sound commercial order by enabling pre-orders or small orders for rebars that meet the needs of buyers by effectively connecting the suppliers and buyers as described above.

Above, those skilled in the art from the above description will know that various changes and modifications are possible without departing from the technical spirit of the present invention. It should be determined by the scope and its equivalent scope.
