Most researches on the corporate credit rating are generally classified into the area of bankruptcy prediction and bond rating. The studies on bankruptcy prediction have focused on improving the performance in binary classification problem, since the criterion variable is categorical, bankrupt or non-bankrupt. The other studies on bond rating have predicted the credit ratings, which was already evaluated by bond rating experts. The financial institute, however, should perform effective loan evaluation and risk management by employing the corporate credit rating model, which is able to determine the credit of corporations. Therefore, this study presents a corporate credit rating method using business failure probability map(BFPM) and AHP(Analytic Hierarchy Process). The BFPM enables us to rate the credit of corporations according to business failure probability and data distribution or frequency on each credit rating level. Also, we developed AHP model for credit rating using non-financial information. For the purpose of completed credit rating model, we integrated the BFPM and the AHP model using both financial and non-financial information. Finally, the credit ratings of each firm are assigned by our proposed method. This method will be helpful for the loan evaluators of financial institutes to decide more objective and effective credit ratings.

In this study, we analyzed the factors affecting the introduction of Smart Factory by domestic SMEs through AHP analysis and tried to provide implications for the introduction of Smart Factory. It was confirmed that the manufacturing and introduction group, the non-manufacturing introduction group, and the already introduced group had the highest weight in the cost reduction in the first hierarchy standard. At this time, it can be seen that the weight for cost reduction is relatively high in the manufacturing introduction group and the introduction group, and the weight for the productivity improvement is relatively high in the non-manufacturing introduction group. It can also be seen that the portion of marketing enhancement does not have a significant impact on smart factory choices. It was confirmed that image enhancement is the highest in the manufacturing introduction group and the non-manufacturing introduction group in the first hierarchy standard, and the marketing has the highest weight in the introduction group. In the two - tiered standard, customer - friendly and proper inventory maintenance weights were relatively high in all the introduced groups, except for the high rankings.

본 연구에서는 최근 꾸준한 성장세를 보이고 있는 의료산업의 국내벤처기업에 대한 신용 평가를 위해 먼저 기업의 재무 요인과 비재무 요인을 구분하여 평가지표를 개발한 다음 Saaty(1980)의 계층분석과정(Analytic Hierarchy Process; AHP)방법론을 적용하여 각 지표의 중요도(가중치)를 산출함으로써 의료벤처기업의 신용평가모형을 제시한다. 재무요인의 상위지표로는 수익성, 안전성, 활동성, 성장성, 생산성을 선택하였고, 각 상위지표에 대해서는 2개씩의 하위지표를 정하여 모두 10개의 지표를 설정하였다. 또 비재무적 요인의 상위지표로는 경영자 능력, 기술성, 시장성, 사업성, 신뢰성의 5개 영역을 정하고, 각 영역에 대해 2-5개의 하위지표를 정하여 모두 17개의 지표를 설정하였다. 신용평가지표에 대한 평가를 위해 원주의료기기클러스터 내 소재하고 있는 금융기관 및 보증기관의 심사역을 대상으로 설문조사를 한 후 이를 분석하여 평가지표에 대한 가중치를 산출하였다.

On the situation cooperating with business partners on the supply chain, systematic decision making process is a critical issue for them. The two major issues of purchasing strategy such as selecting vendors and managing them are important part of their overall business activities. This study mainly focus on the former issue of the vendor selection. Through the empirical study, analytical hierarchy process (AHP) method was applied to select vendors among supplier vendors based on four selection criteria such as the level of quality, product on management ability, delivery, and price. The results of study showed the main criteria of vender selection was the ability of quality management. The vender selected based on AHP and the current selection method was different, but implicitly projected the dilemma situation between quality and price which occurs in decision making process of real life.

The efficient safety estimation for a business should analyze an accident data by considering every possible and potential factor. Thus, we consider several factors to build the safety estimation model to meet fairness and rationality. This paper present the yearly statistic data of accident from KOSHA analyze the data by industry, scale, year of service of a employee, age and other factors; build the safety estimation model for the business based on the accident report derived the analysis. The estimation model is established by the weights for accident type, degree, scale, industry, year of service, and age of the employee derived from AHP(Analytic Hierarchy Process).

본 논문에서는 국내 가상이동망 사업자(MVNO : Mobile Virtual Network Operator) 제도 도입에 대한 논의를 위해 MVNO의 개념, 국내외 사업자 현황, 규제 동향 및 제도 도입의 효과를 분석한다. 아울러 AHP(Analytical Hierarchy Process, 계층적 분석) 기법을 이용하여 정부의 정책개입에 따른 MVNO 사업자의 효율적인 비즈니스 모델을 도출한다. 이를 위하여 사업자의 주요평가기준으로 경쟁활성화, 투자요인증대 및 경제성을 선정하였으며 자율협상, 부분규제 및 전면 규제의 세 가지 대안을 상정하고 각각의 평가기준별 점수를 비교, 분석한다.

This study applies the Analytic Hierarchy Process (AHP) to evaluate service quality of Third-Party Logistics (3PL) service providers. For this, we first conceptualize five dimensions of 3PL service quality (i.e. tangibles, reliability, responsiveness, assurance and empathy). We then apply the AHP method to determining the relative weights of five service quality dimensions and eventually selecting the best 3PL service provider. To implement this idea in practice, we conduct an empirical study on four companies providing 3PL services in Korea.

Object-oriented databases (OODBs) canbe used for many non-traditional database application areas such as computer-aided design, etc. Usually those application areas require advanced modeling power for expressing complicated relationships among data sets. OODBs have more distinguished features than the traditional relational database systems. One of the distinguished characteristics of OODBs is class hierarchy (also called inheritance hierarchy). A class hierarchy in an OODB means that a class can hand down the definitions of the class to the subclass of the class. In other words, a class is allowed to inherit the definitions of the class from the superclass. In this paper, we present performance evaluation metrics for class hierarchy in OODBs from a concurrency control perspective. The proposed performance metrics are developed to determine which concurrency control scheme in OODBs can be used for a given class hierarchy. In this study, in order to develop performance metrics, we use class hierarchy structure (both of single inheritance and multiple inheritance), and data access frequency for each class. The proposed performance metrics will be also used to compare performance evaluation for various concurrency control techniques.

최근의 객체지향 소프트웨어개발에서는 설계 및 유지보수와 관련된 많은 문제점들을 해결하기 위하여 클래스를 재설계하거나 클래스계층구조를 재구성하는 등 객체지향 소프트웨어에 대한 일련의 재이용 및 재구성기법이 사용되고 있다. 본 논문에서는 클래스계층구조의 재구성에 관한 정형적인 이론을 제공함으로써 클래스계층구조의 재구성에 관하여 보다 수월하게 이해하고 적용할 수 있도록 하였다. 구체적으로 본 논문에서는 객체지향 소프트웨어의 개발에 있어서 주요 골격이 되는 클래스계층구조를 평탄화시킨 형태로 정의한 평탄화된 클래스계층구조를 소개하고, 임의의 클래스계층구조를 평탄화된 형태로 변형시키기 위한 알고리즘을 제안하였다. 클래스계층구조를 평탄화함으로써 클래스계층구조상의 계승 및 집약관계가 각 인스턴스들에게 어떻게 사상되는가를 수월하게 파악할 수 있으며, 주어진 클래스계층구조로부터 생성가능한 객체를 그대로 유지보존할 수 있는 평탄화된 형태의 새로운 클래스계층구조를 구축할 수 있다. 평탄화된 클래스계층구조는 클래스계층구조를 재구성하여 객체지향 소프트웨어를 점증적으로 변화 발전시키거나 재이용함에 있어서 기초를 제공하는 등 중요한 역할을 수행한다.
