ABSTRACT

본 논문은 근접 무선 통신 기술(NFC)을 적용하여 박람회 지원 시스템을 구축한 사례와 관람객 행동 데이터(POB: Point of Behaviors)의 분석을 수행한 사례를 소개한다. NFC 기술이 박람회 공간에 적용됨에 따라 관람객은 휴대폰을 통해 다양한 정보를 획득하고 저장, 관리함으로써, 새로운 경험을 하게 되고, 전시자는 NFC 시스템을 통해 획득한 관람객에 대한 데이터 수집 및 분석이 가능하게 되어 관람객과의 CRM 기회를 갖게 된다. 본 연구에서는 ‘2013 내나라 여행 박람회’에 적용된 근접 무선 통신 기반 박람회 지원 시스템의 구축 내용을 소개하고, 수집된 NFC 태그 터치 데이터를 기반으로 날짜 및 부스 별 관람객 수, 관람객의 박람회 체류시간, 관람객 방문 부스 등의 분석을 수행하고, 박람회 현장에서 설문 조사를 실시하여 인구통계학적 정보, 박람회 만족도 등의 데이터를 수집하여 터치 데이터와 교차 분석을 수행한다. 또한 연관 규칙 분석 기법을 이용하여 관람객들이 방문한 부스들 간의 연결 관계를 분석한다.

A Case of NFC-based Exhibition Support System for Analyzing Visitors’ POB(Point of Behaviors)

ABSTRACT

This research introduces a case of NFC (Near Field Communication) – based exhibition support system for analyzing visitors’ POB (Point of Behavior) data gathered from the system. The application of NFC technology to an exhibition space allows visitors new experiences of exposition and exhibitors to collect and analyze data about behaviors of visitors. The NFC-based exhibition support system is applied to the ‘Korea Travel Expo 2013.’ The visitors’ behaviors are analyzed based on collected NFC tag touch data and association rules among booths are extracted. Furthermore, the tag touch data are integrated with the survey data for catching the demographics-based implications.

ABSTRACT

Using the computer simulation method, we invest19ate the probability distribution of maximum eigenvalue of pair-wise comparison matrix, which has been used as a parameter for measuring the consistency of responses in analytic hierarchy process (AHP). We show that the shape of the distribution of the maximum eigenvalue is different according to the dimension of the matrix. In addition, we cannot find any evidence that the distribution of the Consistency Index is a Normal distribution, which has been claimed in the Previous literature. Accordingly, we suggest using so called K-index calcu1ated based on the concept of cumulative distribution function lather than based on that of arithmetic mean because the probabilistic distribution cannot be assumed to be a Normal distribution. We interpret the simulation results by comparing them with the suggestion of Saaty[11]. Our results show that using Saaty's value could be too generous when the dimension of the matrix is 3 and strict over 4. Finally, we propose new criteria for measuring the response consistency in AHP.

ABSTRACT

The sales activity of most of small manufacturing companies is based on orders of buyers. The process of promotion, negotiation, receipt and selection of orders of the manufacturers is closely coupled with the load status of the production lines. The decision on whether to accept an order or not, or the selection of optimal order set among excessive orders is entirely dependent on the schedule of production lines. However, in the real world, since the production scheduling activity is mainly performed by human experts, most of small manufacturers are suffer from being unable to meet due dates, lack of rapid decision on the acceptance of new order. Recently, Internet based Electronic Commerce is recognized as one of the alternatives for strengthening sales power of small and medium companies. However, small and medium manufacturers can’t adjust properly to the new environment because they are in short of money, personnel, and technology. To cope with this problem, this paper deals with development of part sales agent coupled with virtual manufacturing in Internet environment that consist of selection agent, advertisement agent, selection agent, negotiation agent, and virtual manufacturing system. This paper develops a time-bounded negotiation mechanism for small and medium manufacturers in agent-based automated negotiation between customers and negotiation agents. Furthermore, to select optimal order set maximized profit, we first formulate the order selection problem with mixed integer programming, but the computation time of IP is not acceptable for real world scale problem. To overcome this problem and dynamic nature of virtual manufacturing, we suggest a genetic algorithm approach, which shows a reasonable computation time for real world case and good incremental problem solving capability.

ABSTRACT

In an agent-based system, each agent has its own decision making capability and competes, cooperates, and communicates each other with an agent interface. Virtual manufacturing has characteristics as a typical application area of agent-based system: complex and time-bound decision making and negotiation. The time-boundness influences the choice of decision making models and design of protocols for internal and external negotiation. In this paper, we provide a case study which suggests a time-bound framework for external and internal negotiation between the agents for virtual manufacturing environment. We illustrate decision making model selection strategy and the system architecture of the agent-based system for the complex and time-bound environment.

ABSTRACT

국가 목표와 연계된 국가전략을 수립하기 위해서는 국가의 자원과 잠재력, 즉 국가의 자본을 핵심 요소로 고려해야하며, 물적 자본뿐만 아니라 무형 자본적인 측면을 같이 고려해야 한다. 본 논문에서는 국가의 자본 차원을 물적 자본, 인적 자본, 사회적 자본, 디지털 자본으로 분류하고, 이들이 국정운영체제와 주요정책 이라는 매개체를 통해 국가목표 달성에 연계되는 체제를 구상하였다. 이 과정에서 디지털 자본이라는 자본의 요소를 새롭게 정의하고, 이의 필요성을 논의하였 으며, 기존의 지적 자본이론, 무형자산이론, Bourdieu의 자본형태이론, 정보자본 이론 등을 검토하면서, 지적 자본의 구체화와 정보자본의 확장으로서 디지털 자 본 개념의 적실성을 검증하였다. 한국의 국가전략에 있어서 디지털 자본의 역할 을 국정운영과 주요정책 의제를 도출하는 과정에서 예시하여, 본 논문이 제시하는 틀의 유용성을 보였다.

ABSTRACT

Although online social network services widely used in human networking and recruiting industries, it is showing off its limitations in followings-it’s hard to reach the status of seamless connection between offline and online; the incompletion and low credibility of the information came from non-face-to-face profile exchange; and the restraint of user autonomy due to centralized control. This paper defines the ubiquitous social network management which enables the seamless real-time face-to-face social interactions of the users based on WPAN (Wireless Personal Area Network) who share the same interest in real word and deduces a ubiquitous social network management framework based on it. As an instance of ubiquitous social network management, u-Recruiting service model will be designed and analyzed. The Analysis using the business model will be followed by the possible scenario of service model. The role, value proposition and potential benefits of the each participants in this service model and will be given as well. In order to evaluate relative advantages of the model suggested by this study, 6 cases will be compared.
