The classical algorithm for solving liner network flow problems are primal cost improvement method, including simplex method, which iteratively improve the primal cost by moving flow around simple cycles, which iteratively improve the dual cost by changing the prices of a subset of nodes by equal amounts. Typical iteration/shortest path algorithm is used to improve flow problem of liner network structure. In this paper we stdudied about the implemental method of shortest path which is a practical computational aspects. This method can minimize the best neighbor node and also implement the typical iteration which is $\varepsilon$-CS satisfaction using the auction algorithm of linear network flow problem

This study analyzed the structure of pricing in the automobile auction market by using real trade data. We focused on the bidding behavior of bidders and the contract price of exhibits. First, we proposed a relational framework among exhibits, number of bidders, and the contract price. Next, we utilized a neural network model to estimate the number of bidders and the contract price. Subsequently, we investigated the relationship between the number of bidders and the contact price, and evaluated our method through an analysis that employed verifying data. Lastly, we listed our suggestions for bidding in auction markets.

This research Investigates the determinants of customer Intention to participate In Internet auction. Based on technology acceptance and trust related studies, our research proposes a theoretical model consisting of factors such as perceived usefulness, perceived ease of use, institution based trust, beliefs on sellers, trusting beliefs, and participation Intention. For examining the relationships implied by the research model, a field study using a survey methodology for data collection was conducted. The data were analyzed using AMOS based on the structural equation modeling, a second-generation multivariate technique, which has gained distinct advantages over other technique. After some model modification according to model generating strategy approach, this study shows that trusting beliefs have significant effects on the participating intention in Internet auction site. In conclusion, Implications are discussed along with limitations and further research direction.

The purpose of this study Is to analyze the homepage contents of an auction site on the Internet. This study collected 459 cases of purchasing and selling notes, and classified them into three types. The finding showed that some of the most frequently-occurring consumer problems are concerned with delivery and return, and sellers manner. On the other hand, consumers' manner is important to sellers. The auction site itself has problems with consultation and its own system.

In an electricity market, the spot market is normally integrated with a forward or future market. The advantage of the forward market is to allow the market participants to deal in a part or the whole trading portfolio at a fix price in advance and to avoid risk associated to the uncertain price of the spot market. Japan has introduced a continuous auction base forward market from April 2005. This paper analyzes the Japanese forward market rules and operations, and introduces a new algorithm that may improve the efficiency of the market itself. The proposed algorithm enables us to give consideration to the specific characteristics of the power system and to integrate them in the auction mechanism. The benefits of the proposed algorithm are verified on an electronic simulation platform and the results described in this paper.

As the importance of time-based competition is increasing, information systems for supporting the immediate decision making is strongly required. Especially high -tech product firms are under extreme pressure of rapid response to the demand side due to relatively short life cycle of the product. Therefore, the objective of our research is proposing a framework of estimating demand curve based on e-auction data, which is extremely easy to access and well reflect the limited demand curve in that channel. Firstly, we identify the advantages of using e-auction data for full demand curve estimation and then verify it using Agent-Eased-Modeling and Tobin's censored regression model.

We compare impacts of different $CO_2$ abatement mechanisms using a CGE model. Focus is on the way the tradable permits are initially distributed for emissions trading, namely auction and grandfathering. For three major energy consuming industries (basic chemical, iron & steel and electricity) in Korea, emissions trading is clearly superior to individual $CO_2$ abatement, but auction and grandfathering show somewhat different patterns of impact. We show that depending on how the government uses the revenue from permit auction, auction may be preferable to grandfathering.

We propose a new auction protocol scheme that uses the publicly verifiable secret sharing (PVSS) scheme. Unlike the existing scheme where a verifiable encryption scheme is employed when there is a dispute between a bidder and the auctioneer, the proposed scheme essentially removes the potential of a dispute. In addition, it has a robust registration phase and any entities participating in or observing the auction can verify the correctness of the auction process. The manager does not directly chooses the private key for the bidders, but only verifies the correctness between the private key and the public key, thereby improving the security, such as a bid submission of a malicious manager using the private key of a bidder.

In this paper, we survey the auction on the art and the art price index in the international and Korea art market. The auction plays a role on the art market from art creators to art collectors. The auction will grow because it utilizes the open art market. The art price index which is developed to give a guide in art investment. However, the history of art index is short and the developed art index is not well widely used. Since, the art price is opened in the auction, so it provides the necessary condition to develop art price index. In this study, we compare the foreign art price index with the domestic one and we examine the properties and utilization of the art price index in Korea.

This study was intended to identify the problem of the lien in relation to the real estate auction and present its improvements in terms of procedural laws. To resolve the problem of the lien in the real estate auction, it is valid that the Vollstreckungsgericht needs to set the certain standard in relation to the possession of real estate and notify it at the first date of sale by judging whether the lien can be established. And the institutional improvement is required to obligate one to report the lien in the procedures of the real estate auction and reinforce the survey of the present condition of the lien. And it is necessary to impose the more public confidence on the statement of sale by including the matter of the lien in it. In addition, it is necessary to reinforce legal punishment to the false and fictitious lienholder and establish the legal stability of the lien in the process of the real estate auction.
