Definitions

• the invention relates to a method and a device for carrying out an electronic auction in a communication network according to the preamble of claim 1.
• the invention relates to an interactive reverse auction, which is held via the Internet, and in which a large number of bidders submit their bids for a Submit an order that involves the procurement of required products, such as goods or services, to a buyer.
• An auction is usually understood to mean the sale of an object in which several people meet in one place, usually the auction house, in order to submit their bids for the object to be auctioned.
• the objects to be auctioned are presented to the interested parties one after the other and the highest bid for an object is awarded, i.e. the buyer with the highest bid becomes the buyer of the object currently being auctioned.
• Such auctions have the disadvantage that the bidder must be physically present at the location of the auction and, if necessary, have enough time because the exact time of the auction of a certain object is generally not known.
• each bidder makes his bid without knowing the bids of the other bidders, with the highest bid winning the bid.
• Vickrey auction which can also be a closed auction
• the item is sold to the highest bidder at the price of the second highest bid, provided that the selling price is higher than or equal to a predetermined minimum price.
• Another important auction procedure is the English auction, in which an auction opens at a predetermined minimum price and only bids above the minimum price are taken into account and the highest bid wins.
• a Dutch auction the auction with a high offer price opened for the property offered, which is lowered until a bidder agrees to the current price.
• the auctions at which prices increase due to the demand of the bidders are called increasing auctions. This is in contrast to the falling or reverse auction, in which the price decreases as a result of the interest of the bidders.
• a system and a method for carrying out an electronic auction via a communication network is known from EP-0 987 644.
• the system comprises a number of bidder devices which are connected to one or more auctioneer devices, and various auction methods can be carried out.
• Purchasing for example, defines the need, the product and any other boundary conditions in the form of an invitation to tender or a specification, and thus addresses the internet auctioneer.
• This provides an online auction room at a specific time and notifies potential suppliers, including the tender or the specification.
• the maximum price for the product is determined by the buyer.
• the suppliers interested in the auction are trained by the internet auctioneer.
• the auction with the interested suppliers then takes place during the specified period, whereby the auction is limited to a predetermined period. Only during this period can suppliers submit bids for the tendered order online.
• a bidder sees the bids of the other bidders anonymously, whereby generally only the best anonymized bid is displayed.
• the bidder can undercut this best bid at any time during the auction period.
• the purchase is awarded to a bidder, who does not necessarily have to be the cheapest, unless this has been explicitly specified in the auction rules.
• the price will be the decisive criterion for the surcharge, but the cheapest supplier is not always the best for the buyer, since other characteristics such as quality and quality of the goods, production capacity of the supplier for large-scale orders are sufficient Delivery options for certain dates, etc., play an important role.
• the cheapest price cannot be decisive for placing an order if the supplier offering this price cannot deliver on the necessary delivery date due to other delivery obligations, but only at a later point in time.
• a so-called total cost function is introduced in the "eBreviate" reverse auction system, which evaluates the other factors mentioned and sets a fictitious total price from the bid and the evaluated boundary conditions in order to make a more realistic comparison between to allow the commandments.
• reverse auctions on the Internet are already being used for the faster and cheaper procurement of required parts and articles.
• the auction forms used do not yet provide optimal results for the buyer with regard to bidding behavior and the selection of the most suitable bidder for a required product.
• the invention is therefore based on the issue of creating an improved auction process, in particular a reverse auction process, and a corresponding auction device.
• a first method according to the invention for carrying out an electronic online auction between a number of bidders and a buyer via a communication network has the following steps:
• each bidder can submit his bids during the permitted period, which is formed by the specified first period, each bidder is shown at least the lowest bid by competitors in anonymized form and the remaining auction time, and for comparison the bids of the individual bidders are calculated online for each bid, a comparative total cost as a function of the respective price and other suitable criteria, the permissible
• the duration of the auction is extended by an extension interval before it expires, so that a new permissible period results.
• a remaining time interval is preferably defined, with the bidders only being informed of this remaining time interval if the remaining auction time is less than or equal to the remaining time interval.
• An extension of the auction is preferably carried out in the remaining time interval, the duration of the extension interval or intervals being selectable for each extension.
• a second method according to the invention for carrying out an electronic auction with a number of bidders and a buyer for procuring the goods or services required by the buyer via a communication network, which also includes the possibility of extending the permissible auction duration, has the following steps:

• purchasing 1 checks in a preliminary decision 3 based on, for example, an invitation to tender that is sent to possible suppliers and returns, based on whether the product and the supplier offer the Meet buyer's requirements.
• the final bidding group for the online auction results from the group of possible suppliers.
• the selected bidders will be informed about the location, ie the online auction space, the time and the auction duration within the bidding group decision 3. Furthermore, training is carried out for the bidders before the actual auction to ensure that the bidders are familiar with the auction interface.
• the bidders selected in the bidding group decision 3 take part in the online auction 4 and as a result of this auction there is a preliminary decision on the award of the order for the delivery of the auctioned product.
• This online auction 4 can also be an online renegotiation, for example if it turns out during the auction that a subset of the originally selected bidders comes into question as suppliers. Then a bidding group decision 3 no longer has to be carried out, and the online renegotiation, which is also carried out in the form of an online auction, is initiated directly by purchasing 1.

• Every interested supplier 11 submits a first bid to the purchasing department 1 within a predetermined period of time. Furthermore, the bid of the potential supplier must contain statements on the other specifications mentioned in the tender, e.g. whether the supplier can deliver the desired delivery quantity at all or only a part, whether the required quality can be maintained, whether predetermined delivery dates are possible, etc. From the bids received, Purchasing 1 makes a selection from among the suppliers, whereby those suppliers who have been selected to participate in the online auction are referred to as bidders.
