본 연구는 통계적 기법을 이용하여 2001년 이후 발주된 최저가낙찰제도 대상 조달청 시설 공사의 전체 투찰률과 공사 종류, 기업 규모, 투찰 금액, 공종별 투찰률 등을 분석함으로써 건설업체의 투찰 행태와 최저가낙찰제도의 문제점을 고찰하였다. 최저가낙찰제 하에서 건설공사의 투찰률이 하락하고, 투찰 행태가 저가와 고가의 유형으로 양극화되면서 최저가낙찰제도 시장이 건설업체들의 투찰 전략에 따라 왜곡될 가능성이 높은 것으로 분석되었다. 또한, 최저가낙찰제도의 문제점을 보완하기 위해 도입된 저가심의제도가 제대로 작동하지 못함에 따라 제도 개선이 필요한 것으로 나타났다. 따라서 보다 더 효과적으로 저가 투찰을 방지하기 위해서는 입찰자가 스스로 공사 물량과 단가를 산출하는 순수 내역입찰제도를 도입하는 것이 필요한 것으로 판단된다.

과거의 입찰방식은 행정의 투명성과 공정성에 대하여 많은 문제점을 가지고 있고, 조달업체들에게 딴은 비용을 소모시킨다. 이의 해결책으로 일부 공공기관에서 전자입찰을 위한 시스템을 구축하였거나 구축 중에 있다. 그러나 이러한 시스템이 여러 가지 측면에서 많은 문제점을 안고 있다. 따라서 본 논문의 목적은 문헌조사, 설문조사 및 만족도 평가, IDEF 방법론을 통하여 현행 입찰업무의 현황을 파악하고, 향후 구축될 시스템의 개선 방안을 제시하는 것이다. 본 논문의 연구결과 현행 입찰제도 하에서는 업무처리 절차가 불편하다는 지적이 가장 많았고, 현재 운영되고 있는 전자입찰 시스템은 대체적으로 만족하고 있었으며, 향후 진자조달 시스템 구현시 고려해야 할 사항은, 입찰$\cdot$계약 전자처리 표준화, 시스템의 보안, 법, 제도 정비 등이 중요하게 나타났다. 이러한 분석된 요구사항을 반영하여 입찰관리 개선모델을 제안하였고 개선효과를 분석하였다.

입찰프로그램은 민/관으로부터 고지되는 입찰 정보의 수집과 누적된 입찰결과의 통계적 분석방법을 사용하고 있지만 복수예가 추첨을 통한 낙찰방식으로 정확한 낙찰가를 예측하는 것은 쉽지 않다. 따라서 본 논문은 MLP, RNN 등의 방법을 이용하여 전자입찰 사이트인 전기넷에서 취득한 2015년 1월부터 2019년 8월까지 전기공사 낙찰현황 데이터의 정확도 등을 분석하고, 이를 통해 낙찰 하한가에 가장 근접하고 1순위 금액 사이의 금액을 예측하여 낙찰에 필요한 입찰금액을 예측하기 위한 기법을 제안한다.

Purpose While the popularity of C2C auction platforms such as eBay is gradually decreased, this domain is still undermined to explain online bidding behaviors. Online bidders sometimes engage in impulsive bidding due to some of the online auction characteristics. Therefore, this study develops and tests a model of the impulsive bidding exhibited by online bidders in C2C auction platforms. Based on S-O-R framework, our model posits that both perceived time-pressure and competition intensity affect cognitive absorption which ultimately influences the impulsive bidding. Design/methodology/approach This study collected survey data from 214 C2C auction participants, who have prior experience on impulsive bidding and tested both measurement model and structural model by using CB-SEM (covariate-based structural equation modelling) technique. In this study, by using AMOS 20.0, we tested the measurement model for its overall fit, item reliability, and validity and further conducted the structural model to test our proposed hypotheses. Findings Based on our results, we found that perceived tim-pressure and competition intensity were positively related to cognitive absorption. We also found that the cognitive absorption was positively associated with impulsive bidding behavior. In this study, by developing our research model in S-O-R framework, we provide an alternative theoretical mechanism to describe online impulsive bidding behavior.

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.

In a competitive electricity market, the transactions of the electric power can be accomplished through the bidding which is submitted by suppliers and consumers. It is essential that the optimal decision for the bidding is required to take a dominant position in the competition. Therefore, in this paper we presents bidding variables from bidding curves of suppliers and consumers and proposes the algorithm of an optimal bidding strategy using optimal power flow. Furthermore, the variation of the optimal bidding is investigated through numerical studies.

This paper proposes the cost analysis on the energy efficient equipment when this equipment is participated in the demand-side bidding. Conventional demand-side bidding is exercised through load re-distribution. However if this load reduction is exercised by the use of high efficient equipment, its effect will be assumed to be more economical. This paper analyses this cost-benefit effect of high efficient equipment in the demand-side bidding.

This paper presents a schematic process based on the method of eliminating dominated strategies to obtain the optimal bidding strategy Pursuing the Nash equilibrium Point. The Proposed approach is demonstrated for a bidding game in a generation competitive market with 2-dimensional bidding strategy vectors constituting a price-quantity strategy curve.

This paper shows the optimal bidding strategy determination method using Nash equilibrium concept by defining bidding strategy vector. This vector is 2-dimension vector whose components are generation amount and generation cost. Thereby we are able to make all possible strategies and their's payoff table. And then we erase dominated strategies one by one so that we obtain Nash equilibrium, the optimal bidding strategy of generation bidding game.
