In the construction industry, bidding competitiveness is the most basic and important competence of the company. Bidding competitiveness comes from competitive advantage, but the strategy of the company to capture bidding competitiveness varies with the characteristics of the project. In particular, overseas construction is where uniqueness of the construction industry and the specificity of international business coexist. This study analyzes the bidding success ratio and the level of bidding difficulty by project characteristics with 12,952 overseas construction bidding cases. Consequently, it was found that the bidding success ratio of Middle East and North Africa (MENA) and civil engineering was the lowest in each group of project characteristics, and therefore the level of bidding difficulty is high, respectively. In addition, it was confirmed that the bidding success ratio of small size or short duration project was relatively high, and the bidding success ratio of both the negotiated bidding in the bidding method group and the private sector in the client type group was respectively high. However, Kruskal-Wallis test in contract type and period shows that there is no statistically significant difference in the bidding success ratio by group.

In 2009, the Korean international construction industry showed a great performance, totaling 49.1 billion of contract and then this achievement has been considered a key milestone presenting that the international construction industry is one of the primary export industries of Korea. However, because of the construction firms' equalized levels of technology and price competitiveness, the competition among bidders is becoming more intensive. Moreover, this changing market circumstance leads construction firms to apply for bidding with the lowest price that could not meet the expected profitability of a project. Therefore, to develop various strategies based on project characteristics becomes one of the critical capabilities that construction firms should possess. Based on these motives, this study is aimed to investigate associations among number of bidders, contract award rate, profitability on international projects. For the correlation analysis, a set of data is structured by collecting all projects ranging from 1993 to 2009, excluding projects funded by official development and domestic funds. The number of bidders were grouped depending on project characteristics such as market regions, project types, bidding types, and order organization types. As the result of correlation analysis, contract award rate increases as the number of bidders increase, but the relationship between the number of bidders and profitability is negative. Understanding the correlations among variables can be employed in developing strategies to improve construction firms' competitiveness in the international construction market.

생산자로부터 고객에 이르는 상품 공급 활동을 관리하는 경영기법인 공급사슬관리(SCM)는 기존의 폐쇄적이고 정적인 환경에서 개방적이고 동적인 환경으로 변화하고 있다. 이러한 변화에 대응하기 위한 실험이나 연구는 부족한 상황이다. TAC SCM은 동적인 SCM 환경에서 다른 경쟁자들과의 경쟁을 통하여 다양한 SCM 전략을 시험할 수 있다. 본 연구에서는 실시간 SCM 환경에서 능동적 할인 전략을 적용한 에이전트를 설계 및 구현하였다. 능동적 할인은 입찰 성공률에 따라 할인율을 변경하여 적용하여 항상 일정한 생산량을 보유할 수 있도록 한다. 본 연구의 실험 결과에서 제안한 에이전트가 서버에서 제시한 Dummy 에이전트보다도 높은 수익과 안정된 생산을 할 수 있음을 보였다.

Overseas construction orders of domestic companies had been increased significantly in a short period from $10.9 billion in 2005 to $64.9 billion in 2012. However experts are concerned that quality of growth will not support quantitative growth. This study suggest concentrate competencies for not only winning in bid but also successful execution of domestic companies. 4 Steps which are Pre-Marketing, Bid-Preparation, Bidding, Contract Phase are defined for competency assessment. After drawing specific tasks by phase, survey asking importance and capability of the tasks to the person in charge of bidding and site was conducted by utilizing Likert 7 point scale. According to the result of IPA analysis, domestic construction companies need to ensure internal competencies; Project risk review, Bid team organization, and external competencies; Client needs grasp, Localization strategy, Cooperation establishment. Hearafter domestic construction companies will be able to utilize the result of the study for setting bidding strategy for winning in bid and improving earning rate.

Recently, various information and data are efficiently used by the rapid growth of its Internet in our real life. But, users have spent lots of time finding necessary information for the increased amounts of information. To solve this problem, it can be provided the speed, accuracy of information search with development of intelligent search engines, agent system etc. In this paper, we propose the method of getting the best tender price in the analysis of the construction bid information that needs its professionalism by on the purpose to maximize users' satisfaction. Of course, if it is not under the unit of a results in the future, we put target of this paper on part to heighten supreme successful bid success rate. Therefore, this paper embodies offered system of web based on producing tender price of most suitable through techniques to produce tender price about successful bid that compare with bidder fare by statistical analysis incidental and value approaching successful bidder fare by frequency analysis method.

To develop a software, there is a relationship between development organization's productivity, effort, development schedule, and software size. It is software equation that motive these relations. Basically, relationship between size-effort and size-schedule is applied. If this relationship is not proper, there would be no effect of the cost-schedule tradeoff equation that is derived from software equation, and the manpower profile analysis, etc. To solve these unwanted problems, we presented a modified software equation and a cost-schedule tradeoff model based on the modified software equation. To improve software development success rate, applying proposed model will help in contract negotiation or bid.

Using bidding data collected from the World Bank's open database, this research performed a series of competitive analyses of the major countries that have participated in the Bank's engineering consulting services contracts in Vietnam. The goal of the analysis was to evaluate the performance of Korean engineering firms to date, and provide strategic recommendations for future projects. Results showed that Korean firms had a high bid acceptance rate, comparable to major developed countries. The success was attributed to the high technical scores in the selection process. Comparatively, financial scores were not competitive and inferior to developing countries such as China and India. Results of a 'Skitmore' analysis revealed that Korea was competitive in medium size projects and were situated between developed and developing countries. Korea thus needs to increase participation in basic and detailed design services, 2) improve labor costs through 'localization' and latest technologies, and 3) and venture into larger sized projects.
