The objective of this study is to develop a supply chain-based freight distribution channel choice model considering shippers' logistics behaviors which will be used for freight demand estimation. For this purpose, this study utilized the distribution channel data of the petrochemical and automobile industries collected by KTDB center. The distribution channel choice models for these industries were developed by including transport mode, time, cost, and shipment size. It was found that the multinomial logit model with transport cost, time and shipment size is the best, and as shipment increases, bigger transport mode is preferred. Generally direct distribution channel with small truck was preferred over the one using distribution center and/or big truck.

Supply chain management is a strategic thinking which enhances the value of supply chain and adapts more promptly for the changing environment. For the seamless partnership and value creation in supply chains, information and knowledge sharing and proper partner selection criteria must be applied. Thus, the partner selection criteria are critical to maintain product quality and reliability. Each part of a product is supplied by an appropriate supply partner. The criteria for selecting partners are technological capability, quality, price, consistency, etc. In reality, the criteria for partner selection may change according to the characteristics of the components. When the part is a core component, quality factor is the top priority compared to the price. For a standardized component, lower price has a higher priority. Sometimes, unexpected case occurs such as emergency order in which the preference may shift on the top. Thus, SCM partner selection criteria must be determined dynamically according to the characteristics of part and its context. The purpose of this research is to develop an OWL model for the supply chain partnership depending on its context and characteristics of the parts. The uncertainty of variable is tackled through fuzzy logic. The parts with preference of numerical value and context are represented using OWL. Part preference is converted into fuzzy membership function using fuzzy logic. For the ontology reasoning, SWRL (Semantic Web Rule Language) is applied. For the implementation of proposed model, starter motor of an automobile is adopted. After the fuzzy ontology is constructed, the process of selecting preference-based supply partner for each part is presented.

The main purpose of this paper is to propose a sophistication framework for a global manufacturing network (GMN) driven by a mother company to autonomously propagate and coordinate transaction data that are exchanged among manufacturing partners. The framework is based on conceptual fundamentals of previous research that provide a step toward ultimate successful collaboration in the supply chain and employs mobile agents for the coordination and propagation of transaction data. Maintaining the integrity of transaction data linked to a huge information web is difficult. With the sophistication functionalities of this framework, it becomes easy to effectively control the overall GMN operations and to accomplish the intended goals. The current level of sophistication focuses on the transaction data propagation. The sophistication level may be expanded up to business intelligence in the future.

The development of ICT has leaded the diversification and changes of supplies and demands in markets. It also caused the creations of a variety of values which are differentiated from those in the existing market. Therefore, a new-type market is created, which can include multi-value chains which are from ICT-based created markets as well as the existing markets. We defined the platform as the new-type market. In the platform, the multi-value chains can be coexisted with multi-values. In true market, when a new-type value chain entered into an existing market, it is general that it can be conflicted with the existing value chain in the market. The conflicted problem among multi-value chains in a market is caused by the sharing of limited market resources like suppliers, consumers, services or products among the value chains. In other words, if there are multi-value chains in the platform, then it is possible to have conflictions, overlapping, creations or losses of values among the value chains. To solve the problem, we introduce coexistence factors to reduce the conflictions to reach market equilibrium in the platform. In the other hand, it is possible to lead the creations of differentiated values from the existing market and to augment the total market values in the platform. In the early era of ICT development, ICT was introduced for improvement of efficiency and effectiveness of the value chains in the existing market. However, according to the changed role of ICT from the supporter to the promotor of the market, ICT became to lead the variations of the value chains and creations of various values in the markets. For instance, Uber Taxi created a new value chain with ICT-based new-type service or products with new resources like new suppliers and consumers. When Uber and Traditional Taxi services are playing at the same time in Taxi service platform, it is possible to create values or make conflictions among values between the new and old value chains. In this research, like Uber and traditional taxi services, if there are conflictions among the multi-value chains, then it is necessary to minimize the conflictions in the platform for the coexistence of multi-value chains which can create the value-added values in the platform. So, it is important to predict and discuss the possible conflicted problems between new and old value chains. The confliction should be solved to reach market equilibrium with multi-value chains in the platform. That is, we discuss the possibility of the coexistence of multi-value chains in the platform which are comprised of a variety of suppliers and customers. To do this, especially we are focusing on the healthcare markets. Nowadays healthcare markets are popularized in global market as well as domestic. Therefore, there are a lot of and a variety of healthcare services like Traditional-, Tele-, or Intelligent- healthcare services and so on. It shows that there are multi-suppliers, -consumers and -services as components of each different value chain in the same platform. The platform can be shared by different values that are created or overlapped by confliction and loss of values in the value chains. In this research, as was said, we focused on the healthcare services to show if a platform can be shared by different value chains like traditional-, tele-healthcare and intelligent-healthcare services and products. Additionally, we try to show if it is possible to increase the value of each value chain as well as the total value of the platform. As the result, it is possible to increase of each value of each value chain as well as the total value in the platform. Finally, we propose a coexistence model to overcome such problems and showed the possibility of coexistence between the value chains through experimentation.

새로운 IT 환경에서의 변화를 이해하고 경쟁력 있는 클라우드 생태계를 구축하며, 지속가능한 성장을 위한 경쟁정책을 수립하기 위해서는 먼저 우리나라 IT시장의 구조와 그 변화를 정확히 이해하는 것이 필요하다. IT시장의 구조를 이해하기 위한 과거의 선행연구들은 통신시장을 배경으로 수직적 가치사슬 구조를 중심으로 설명한 것이 대부분이었으나, 최근 들어 이슈로 부각하고 있는 클라우드 생태계에 관한 연구는 부족한 실정이다. 본 연구의 목적은 IT시장에서의 클라우드 서비스의 등장에 따른 가치사슬의 변화를 이해하는 것이다. 이를 위해 먼저 기존의 연구 문헌들을 통하여 기업 또는 산업의 공급 구조, 그리고 시장의 생태계를 설명하기 위해 사용하는 기본 틀인 가치사슬의 개념을 정의하고, 이를 통하여 우리나라 IT시장의 가치사슬에 대해, 특히 클라우드 서비스 도입이후의 우리나라 IT시장의 변화를 반영하여 그 구조의 변화를 설명하며, 이를 바탕으로 우리나라 IT시장을 진단하고 시장의 성장을 견인하는 요인들을 파악하도록 한다. 본 연구를 통해 가치사슬 관점에서 IT시장을 이해함으로써, 클라우드 서비스 산업의 경쟁력을 높이고, 향후 클라우드 기반으로 IT생태계를 구축하기 위한 이론적 근거로 활용되길 기대한다.

기업은 날이 갈수록 심화되는 경쟁 환경에 대비하기 위해 많은 공급업체들과의 협력관계를 점차 강화해나가고 있다. 정보기술이 발전함에 따라 기업들은 SCM (Supply Chain Management)을 도입하여 이를 실현해나가고 있는 추세이다. 이에 따라, 공급사슬상의 관련 기업간의 상호작용과 정보공유에 기반한 공급사슬 통합이 추진되고 있으며, 정교한 관리를 위해 프로세스 간의 통합을 통해 하나의 글로벌 프로세스로서 SCM을 관리할 필요가 대두되고 있다. 이러한 관점에서 프로세스를 하나의 객체로서 관리하는 BPM (Business Process Management)을 활용하여 SCM을 체계적으로 관리할 필요가 있다. 그러나, 지금까지의 BPM은 비즈니스 프로세스의 자동화 및 통제 등에 주력해왔기 때문에, 전체 프로세스 관점에서 이를 효율적으로 실행하는 기능을 제공하지 못하고 있다. 따라서, BPM을 통해 SCM 프로세스를 단순히 자동화하여 실행한다면, 각 참여 업체들이 글로벌 프로세스의 관점에서 효율적으로 업무를 수행하기 어렵다. 본 논문에서는, 각 공급업체들이 전체 프로세스 관점에서 효율적으로 업무를 수행하는 방법을 제안한다. 제안한 방법을 통해 각 업체들은 전체 프로세스 내 관련 경로의 긴급도 및 관련 업무의 우선처리순위 정보를 제공 받을 수 있다. 따라서, 관련 정보를 토대로 각자의 업무를 수행하기만 하면, 글로벌 SCM 프로세스의 효율성을 향상시킬 수 있을 것이다.

This Paper deals with a collaborative decision making procedure of web-based DSS for supply chain management (SCM). The seemingly autonomous DSS dedicated to each of mutually exclusive prob1em domains forms a communication network and cooperates each other for better SCM decision making. We a1so propose a hub-spoke information sharing model for the DSS network. In the hub-spoke model, an information hub at the center facilitates information exchange between DSS\\`s and controls the conversations defined by the series of XML messages between agents of DSS. A product ordering scenario where supply decision is triggered upon customer order is used to demonstrate the SCM decision procedure through a collaboration of the web-based DSS.
