Due to the active use of the internet currently, the transportation volume of logistics firms is dramatically increasing, but it is not easy to secure available vehicles and vehicle suppliers, so it is the most important for logistics companies to streamline transportations management and process. For such reason, there have been a number of studies to deal with VRP and VSP for efficient vehicle allocation planning of vehicle suppliers and vehicles. But it is hard to reflect traffic situations changing everyday and detailed geographic conditions, and it requires big scale of database and huge calculation time consumption as increase number of depots, which is very inefficient. For solving the vehicle allocation planning problems of 3PL firms with various constraints due to the transportation cost, this paper suggest new vehicle allocation information system and an algorithm based transportation cost/income. Also this paper presents actual results applied to a logistics company. As a result, the transportation profit of vehicle suppliers increased by 11 percent in average, when the developed transportation cost-based vehicle allocation system applied.

According to statistics, it is shown that domestic SMEs rely on bank loans for the majority of fund procurement. From financial information shortage (Thin file) that does not provide information necessary for credit evaluation from banks such as financial statements. In order to overcome these problems, recently, in alternative finance such as P2P, using differentiated information such as demographics, trading information and the like utilizing Fintech instead of existing financial information, small funds A new credit evaluation method has been expanding to provide SMEs with small amounts of money. In this paradigm of environmental change, in this research, credit evaluation which can expand fund supply to SMEs by utilizing big data based on trade area information such as sales fluctuation, location conditions etc. In this research, we try to find such a solution. By analyzing empirically the big data generated in the trade area, we verify the effectiveness as a credit evaluation factor and try to derive the main parameters necessary for the business performance evaluation of the founder of SMEs. In this research, for 17,116 material businesses in Seoul City that operate the service industry from 2009 to February 2018, we collect trade area information generated for each business location from Big Data specialized company NICE Zini Data Co., Ltd.. We collected and analyzed the data on the locations and commercial areas of the facilities that were difficult to obtain from SMEs and analyzed the data that affected the Corporate financial Distress. It is possible to refer to the variable of the existing unused big data and to confirm the possibility of utilizing it for efficient financial support for SMEs, This is to ensure that commercial lenders, even in general commercial banks, are made to be more prominent in one sector of the financing of SMEs. In this research, it is not the traditional financial information about raising fund of SMEs who have basically the problem of information asymmetry, but a trade area analysis variable is derived, and this variable is evaluated by credit evaluation There is differentiation of research in that it verified through analysis of big data from Trading-area whether or not there is an effect on.

Purpose: With the diversification of modern society, it is difficult to predict crime types, and the limitations of the state's functions, such as human limitations and lack of budget, are increasing. Method: However, as the number of private investigation companies that do not use illegal means to solve the request increased, attempts were made to introduce a public detective system that would manage and supervise it and compensate for the gap in public power. Result: However, due to the nature of the Private Investigator system, legislation has not progressed as the National Police Agency and the Ministry of Justice are at odds with existing laws that guarantee existing jobs such as lawyers and credit research. Conclusion: Therefore, this study analyzes the bills related to the authorized detective to the National Assembly, examines major issues such as the scope of work of the authorized detective business, the selection of management and supervisory authorities, and suggests ways to improve the successful settlement of the Private Investigator system.

무역거래의 패턴이 최근 크게 변화하고 있는데, 기존 무역거래방식에서 인터넷무역방식으로 그 비중이 확대되면서 인터넷 무역거래알선사이트에 관한 관심과 활용도가 점차 높아지고 있으며 특히 무역거래알선사이트의 구축 및 운영은 국내외의 무역 유관기관과 지방자치 단체, 대기업 종합무역상사 및 개별기업을 중심으로 활발히 진행되고 있다. 이에 실제 우리 나라 무역업체들의 사이트 이용 및 현황과 이용만족도 조사를 위해 설문조사를 한 결과, 현재까지 무역업체들이 가장 선호하는 사이트는 무역 유관기관이 운영하는 사이트들이다. 또한 실제 무역거래알선사이트를 이용한 결과와 관련하여 거래알선사이트 제공서비스에 대한 만족은 대상 업체 중 불과 17.9%의 낮은 수준으로서 이렇듯 낮은 만족도를 보이는데는 다음과 같은 문제점들이 있었다. 즉, 정보 인프라 측면에서의 관련정책의 분산, 보안 인프라의 우려, 오프라인 상의 결제 및 세금문제, 인터넷무역 관련 국제협력문제 등을 들 수 있으며, 무역업체의 측면에서는 전문인력의 부족, 최고경영자의 정보화 인프라에 대한 마인드 부족과 업체내의 웹 기반 환경 구축 미흡 등을 들 수 있다. 이상의 문제점들을 개선하기 위한 활성화방안을 살펴보면 첫째, 거래정보 보호기술의 육성 둘째, 무역거래알선사이트의 적극적인 국내외 홍보 셋째, 무역거래알선사이트 관련 분쟁 신용조회 등의 통합관리 넷째, 사이트관련 온라인과 오프라인상의 제반환경 개선 및 국제거래 규약 개선 다섯째, 무역거래알선시스템의 효율성제고를 위한 전문인력 양성 및 교육훈련 강화 등이 절실히 요망되고 있다.

Undecided inference could be regarded as a missing data problem such as MARand MNAR. Under the assumption of MAR, undecided inference make use of logistic regression model. The probability of default for the undecided group is obtained with regression coefficient vectors for the decided group and compare with the probability of default for the decided group. And under the assumption of MNAR, undecide dinference make use of logistic regression model with additional feature random vector. Simulation results based on two kinds of real data are obtained and compared. It is found that the misclassification rates are not much different from the rate of rawdata under the assumption of MAR. However the misclassification rates under the assumption of MNAR are less than those under the assumption of MAR, and as the ratio of the undecided group is increasing, the misclassification rates is decreasing.
