Turnkey and alternative-design contracts was introduced operation in the country from january 2004 to February 2010. this was introduced operation. The selecting method of contractor for turnkey projects has being operated by an open forum type that consists of technical committee and appraisal committee in an integrated design approach deliberations. But to improve the operation of the problems, the government is operating design review committee consisting of the central, local and special design advisory committee in march 2010. But this system has also been suggested as still problems, too many contracts by large companies, increasing of design cost and excessive competition. This study is intended to contribute that turnkey and alternative-design contracts can be well operated in domestic construction markets. In this paper suggests some improvement methods and operational problems caused from application of an open forum type for selecting contractor of turnkey project.

This study was conducted to provide basic data for a transparent and fair bidding system by identifying problems and suggesting improvement measures through an analysis of the bidding status for construction projects and service-related landscaping of multi-family housing. To this end, we used the data from the "Multi-Family Housing Management Information System (K-apt)" that provides the history of apartment maintenance, bidding information, and the electronic bidding system to examine the winning bid status and amount, along with the size and trends of the winning bids by year, and the results of the selection of operators by construction type. As a result, it was found that out of the total number of successful bids (36,831), 4.4% (16,631) were in the landscaping business, and the average winning bid value was found to be about 24 million won. According to the data, 73% of the landscaping cases were valued between 3 million won and 30 million won, and 58.6% of the cases were in the field of "pest prevention and maintenance". 36% of the total number of bids were awarded from February to April, with "general competitive bidding" accounting for 59.8% of the bidding methods. As for the method of selecting the winning bidder, 55% adopted the "lowest bid" and "electronic bidding method," and 45% adopted the "qualification screening system" and "direct bidding method." As an improvement to the problems derived from the bidding status data, the following are recommended: First, the exception clause to the current 'electronic bidding method' application regulations must be minimized to activate the electronic bidding method so that a fair bidding system can be operated. Second, landscaping management standards for green area environmental quality of multi-family housing must be prepared. Third, the provisions for preparing design books, such as detailed statements and drawings before the bidding announcement, and calculating the basic amount shall be prepared so that fair bidding can be made by specifying the details of the project concretely and objectively must be made. Fourth, for various bidding conditions in the 'business operator selection guidelines', detailed guidelines for each condition, not the selection, need to be prepared to maintain fairness and consistency. These measures are believed to beuseful in the fair selection of landscaping operators for multi-family housing projects and to prepare objective and reasonable standards for the maintenance of landscaping facilities and a green environment.

국민권익위원회는 지난 11월 1일 공공기관이 물품구매와 관련한 계약을 할 때 생길 수 있는 불합리한 관행을 개선하기 위해 '물품구매 계약의 합리성 제고 방안'을 마련하여 관계 부처인 기획재정부 및 행정안전부에 제도개선을 권고했다. 권익위는 '국가를 당사자로 하는 계약에 관한 법률 시행령'에 시설공사와 물품구매 등에 대한 정의 규정을 신설하는 등의 발주방식 판단기준을 마련할 것을 권고했다. 또한 시설공사를 물품제조나 구매로 발주하지 못하도록 입찰공고 시에 발주방식 준수의무를 '정부 입찰계약 집행기준'과 '지방자치단체 입찰 및 계약집행 기준'에 포함하는 방안도 제시했다. 아울러 공사나 물품, 용역 등 계약 목적이 겹치거나 혼합될 경우에는 주된 목적으로 발주방식을 결정하도록 하는 내용을 계약법에 신설하는 방안도 권고안에 포함했다. 국민권익위 관계자는 "이번 개선안이 수용되면 물품구매계약 과정에서 발생하는 불합리한 관행 및 제도가 개선되어 물품구매 계약의 합리성이 제고될 것"이라고 밝혔다.

The bidding program uses statistical analysis method of the collected bidding information and the accumulated bidding results from the public/private sector; however, it is not easy to predict the accurate bidding price by winning the bid method through multiple lottery. Therefore, this paper analyzes the accuracy of the current state data of the electric construction bid from January 2015 to August 2019 acquired from the electric net, which is an electronic bidding site, We use MLP and RNN method, and proposes a technique to predict the bidding amount necessary for the winning bid by predicting the amount between the first and the lowest bidder.

Traditional bidding process and activities in public construction area has many problems in terms of the clearness and fairness of administration. And, it causes many cost consumption to suppliers. As part of the efforts to solve these problems, some public institutions developed the electronic bidding systems. But these systems have still problems in diverse aspects. Therefore, the purpose of this study is to analyze current bidding systems through literature survey, case study and process mapping methodology, to compare the result of the analysis with the developed electronic bidding systems and to suggest the improvement for the coming bidding systems. As results of this study, key processes and classified contract types about public construction bidding were identified. These can be applied by means of guidelines when public institutions are planning new electronic bidding systems. The composition of unified driving organization, the database development for information share and the standardization of national level for the new electronic bidding systems were also suggested.

기존의 인터넷 경매시스템에서는 경매 대상 상품을 게시하고 경매참가자들이 입찰가격을 제시한 후 가장 높은 입찰가를 제시하는 경우에 거래가 낙찰되는 형식이 사용되고 있다. 이러한 방식은 사용자의 편의성을 고려하지 않을 뿐만 아니라 경매 참여자에게 지속적인 입찰제시와 확인 등을 요구하기 때문에 고객 편의를 위한 자동 일괄 처리를 만족시키지 못하고 있다. 본 논문에서는 경매 상품에 대한 입찰 히스토리와 경매시간, 경매방법, 낙찰가격 등을 계산하여 해당 상품에 대해 판매자가 어느 시기에 얼마의 초기 가격으로 경매를 시작하면 최대한의 마진을 남길 수 있는지에 대해 메일로 푸쉬해 주는 멀티에이전트 시스템을 제안한다.

수요자원은 전력수급 관리에 있어 중요한 위치를 차지할 것으로 보고 있다. 특히 일본 지진과 관련하여 원전사고는 신규 발전소의 입지 난과 환경문제들을 더욱 불거지게 하였으며 전력수급문제가 공급 측면에서만 해결될 수 없으며 수요측면에서도 적극적으로 관리할 필요성이 대두되었다. 본 논문에서는 수요자원이 시장에 연계하여 활용될 수 있도록 수요시장 입찰 참여방식에 대해 검토하였다.
