Description

Bidding management system for e-bidding {E-BIDDING MANAGEMENT SYSTEM}

The present invention relates to a bid management system for e-bidding, and more particularly, to a bid management system for e-bidding implemented so as to provide bidders with bidding information that can guarantee optimal profits.

In general, Electronic Bidding is a bidding method that allows you to participate in product procurement or facility construction bidding through the Internet without having to visit a bidding site and submit bidding documents. The government, local governments, public institutions, and other organizations In relation to facility construction, goods, services, etc., the Public Procurement Service or its own e-bidding system conducts bid announcements, bids, and open bids to finally determine and select a successful bidder.

'Nara Market', a national comprehensive electronic procurement system that was previously only available in the public sector such as public institutions, city/gun offices, and schools, has recently been opened to the private sector as well. It is designed to select contractors using the provincial market electronic bidding system.

Due to the expansion of the electronic bidding industry, many companies or organizations that want to participate in bidding collect information from bid announcements and analyze available bid announcements before placing a bid. There were difficulties in the analysis. In order to solve this difficulty, there are websites that provide bidding-related information to bidding participants, but only simple information such as bidding information and successful bid results are provided so that the bidding participants are unable to use them properly.

On the other hand, the above-mentioned background art is technical information that the inventor possessed for the derivation of the present invention or acquired in the process of derivation of the present invention, and it cannot necessarily be said to be a known technique disclosed to the general public before the filing of the present invention. .

The communication module 410 receives basic information necessary for calculating the performance score from the bidding management server 200 through the network (N).

The calculation module 420, when there is a deduction in the fulfillment ability score, the minimum bid rate at the minimum price score determined in consideration of the deduction of the fulfillment capacity score, and the minimum bid rate (a lower bid rate) when the fulfillment ability score is a perfect score determines the difference in the minimum bid rate, which is the difference between

The search module 430 searches past bidding information including bid rates of a plurality of companies.

The selection module 440 sorts the bid rates of a plurality of companies in descending order, and selects at least one or more candidate sections in which a difference between adjacent bid rates (adjacent bid rates) is greater than a minimum bid rate difference.

The determination module 450 selects the largest possible value among the values smaller than the past company evaluation rate corresponding to the large bidding rate among the two bidding rates corresponding to the candidate section, and uses this to determine the recommended firm evaluation rate. .

Accordingly, the public bidding terminal 400 will be able to provide a bidding price recommendation service that can obtain a negotiation advantage by excluding competition with other companies when there is a deduction in performance capability.

The braking plate 8233 is connected to the front surface of the seating plate 8231 and forms a close contact leg gear G having a shape corresponding to the braking rack gear 833 on the front surface opposite to the braking rack gear 833, , as the seating plate 8231 advances, it is in close contact with the braking rack gear 833 to brake the hexagonal frame 832 from further lowering.

The sliding groove 8234 is formed to extend in the vertical direction along the front surface of the seating plate 8231 so that the sliding bar 8236 is seated and slides in the vertical direction, and an elastic body 8235 is installed at the lower side.

The elastic body 8235 is installed under the sliding groove 8234 to support the sliding bar 8236 seated in the sliding groove 8234 by using an elastic force.

The sliding bar 8236 is installed on the rear surface of the braking plate 8233 opposite to the sliding groove 8234 , is seated in the sliding groove 8234 , slides in the vertical direction, and is supported by the elastic body 8235 .

The above-described embodiments are for illustration, and those of ordinary skill in the art to which the above-described embodiments pertain can easily transform into other specific forms without changing the technical idea or essential features of the above-described embodiments. You will understand. Therefore, it should be understood that the above-described embodiments are illustrative in all respects and not restrictive. For example, each component described as a single type may be implemented in a dispersed form, and likewise components described as distributed may be implemented in a combined form.

The scope to be protected through this specification is indicated by the claims described below rather than the above detailed description, and it should be construed to include all changes or modifications derived from the meaning and scope of the claims and their equivalents. .
