The Bidding System of the public IT project in Korea is fallen behind, because of the ordering habitual practice based old system, overcompetition based sealed bid and subcontract practice. To innovate this old-fashioned practice for public IT project bidding, this paper wants to generate a proper improvement direction of the public IT project contract law and the related policy through the literature review about the ordering and receiving system in Korea, the practical survey about bidding marketplace in Korea, and competition between bidding system and/or policy of major countries: USA, UK, France and Japan. As a result of practical survey, many problems of the current public IT project bidding system came out and improvement ideas toward future situation turned up. These outputs implicate that the current law and system related public IT project demands better improvement work for the future ubiquitous Korea. Therefore, this paper, to solve these problems about bidding systems and practice, propose the new public IT project contract law and the related policy, reflecting these improvement ideas by the practical survey and the literature review, and benchmarking points from bidding system of other countries.

This paper offers a competitor analysis model for use by contractors as parts of more informed approach in identifying key competitors, and as a basis for formulating bidding strategies. Linear mixed model approach is used in measuring competitiveness between bids (by using bid competitiveness percentage) according to: (i) project size, (ii) work sector; (iii) work nature; and (iv) number of bidders. The model was tested empirically by application to a bidding dataset obtained from a large Hong Kong contractor. Allowing for heterogeneity across competing contractors (i.e. with the model parameters that varied across contractors), the results indicate that competitiveness in bidding of this contractor is generally greater than the majority of his competitors.

Design-bid-build (DBB) is the most common project delivery method among highway projects. State Highway Agencies (SHAs) usually apply a low-bid approach to select contractors for their DBB projects. In this approach, the Federal Highway Agency suggests SHAs heighten contractors' competition to lower bid prices. However, these attempts may become ineffective due to collusive bidding arrangements among certain contractors. One common strategy is the rotation of winning bidders of a group of contractors who bid on many of the same projects. These arrangements may also be specific to a particular region or vary in time. Despite the practices' adverse effects on bidding outcomes, an effective model to detect red-flag bidding patterns is lacking. This study fills the gap by proposing a novel framework that utilizes pattern mining techniques and statistical tests for unusual pattern detection. A case study with historical data from an SHA is conducted to illustrate the proposed framework.

Grid computing is a new technology which involves efforts to create a huge source of processing power by connecting computational resources throughout the world. The key issue of such environments is their resource allocation and the appropriate job scheduling strategy. Several approaches to scheduling in these environments have been proposed to date. Market driven scheduling as a decentralized solution for such complicated environments has introduced new challenges. In this paper the bidding problem with regard to resources in the reverse auction resource allocation model has been investigated and the new bidding strategies have been proposed and investigated.

Best value is the ultimate goal of the owner and can thus have diverse meanings according to the project characteristic, owner's purpose, user groups' payment capability, etc.. Recently, resettlement problems of the marginalized members in the urban regeneration area have been issued in Korea because they have no capability to purchase (or lease) redeveloped housing (or apartment). It means that a minimized production cost for reducing supply price of housing is a key factor in establishing the best value of the marginalized members. The lowest-price bidding system serves the purpose of ensuring a minimized production cost, but due to the low-cost investments, it creates various problems, such as sloppy construction, lowered quality, an increased LCC, and worsening profitability for builders. Thus, to help them resettle, it is necessary to supply affordable housing geared towards a certain appropriate quality and minimum construction costs. Towards this end, this study aimed to propose a cost reduction bidding system based on a technical proposal. The proposed technical-proposal-based cost reduction bidding system consists of the following components: work-unit-based, project-unit-based, and construction-period-reducing technical proposals. These components are evaluated to select the best bidder for a given project. The technical proposal based cost reduction bidding system proposed herein is expected to provide facilities with appropriate supply prices and appropriate quality levels, to bolster the technological competitiveness of builders.

In an electricity market with imperfect competition, participants devise bidding plans and transaction strategies to maximize their own profits. The market price and the quantity are concerned with the operation reserve as well as the bidding system and demand curves in an electricity market. This paper presents a market model combined by an energy market and an operating reserve market. The competition of the generation producers in the combined market is formulated as a gaming of selecting bid parameters such as intersections and slopes in bid functions. The Nash Equilibrium (NE) is analyzed by using bi-level optimization; maximization of Social Welfare (SW) and maximization of the producers' profits.

건설산업에 있어 입찰 경쟁력은 기업의 가장 기본적이며 중요한 역량이다. 입찰 경쟁력은 기업이 보유한 경쟁우위에 기인한 것이나, 입찰 경쟁력을 확보하기 위한 기업의 전략은 결국 프로젝트의 특성에 따라 달라질 수 있다. 특히 해외건설은 건설업의 고유성과 해외사업이라는 특수성이 공존하는 분야로, 본 연구는 국내기업들이 도급형 방식으로 실시한 12,952건의 해외 프로젝트 입찰 사례를 수집하여 프로젝트 특성에 따른 입찰 성공률을 분석하고 그 차이를 확인하여 상황별 입찰 난이도를 진단하였다. 분석 결과, 지역별로는 중동 지역에서, 공종별로는 토목 부문이 입찰 성공률이 낮아 입찰활동에 대한 난이도가 높음을 파악할 수 있었다. 또한 프로젝트 규모나 기간이 작은 그룹이 상대적으로 입찰 성공률이 높음을 확인하였고, 입찰방식에 따라서는 수의시담 방식이, 발주자 형태별로는 민간부문 발주 프로젝트의 입찰 성공률이 높은 것으로 분석됐다. 반면 계약방식이나 시대구분의 경우 Kruskal-Wallis test 결과, 그룹 간 기업별 입찰 성공률이 통계적으로 유의미한 차이가 없음을 확인하였다. 본 연구는 산업차원에서 해외건설 프로젝트 특성요인에 따른 입찰 성공률을 다각적으로 분석했을 뿐 아니라 해외건설 실무자에게 상황별 수주활동 난이도 진단 및 효과적인 입찰전략 수립을 위한 기초자료를 제공한다는 점에서 의의가 있다.

Turnkey project in construction which accounts for about $10\%$ of the total annual construction orders in the nation is expected to grow in size as an effort to strengthen international competitiveness and improve quality of construction work. However, problems of turnkey project in construction raise concern for many possible cases of possible claims. Based on the understanding that bidding guidelines which plays a critical role in turnkey project in construction actually contain some unequal clauses and causes for problems which undermine development of turnkey construction and further create possible cases of claims, the paper aims to identify and analyze the unequal clauses and problems contained in the guidelines in order to make suggestions for improvement. Among all the turnkey construction orders that has been placed since 2000 when domestic turnkey project in construction became relatively formulated, 13 constructions costing more than 50 billion won were selected for this study since their construction scale were large enough that the bidding guidelines for them were regarded as containing little difference among one another. In order to enhance construction technology and to prevent claims while trying to achieve the original purpose of Turnkey system, the parties involved in or schedule to take part in Turnkey project including ordering institution, Construction Company and Design Company should make an effort to have more reasonable bidding guidelines drawn up.
