This study gathered the factors of supply chain risk through literature review, and measured the importance of risk factors recognized by domestic companies. The purpose and necessity of this study are as follows. First, supply risk factors were classified and explored through empirical studies about supply chain risk. Most of the previous studies concentrated on the meaning of supply chain risk, but only in terms of concept approach Second, to evaluate the importance of supply-chain risk recognized by the companies, AHP(Analytic Hierarchy Process} method was proposed in this paper. Finally, this study suggests implications for companies' efficient supply activity by measuring the importance of supply-chain through AHP(Analytic Hierarchy Process).

The purpose of the present study is to analyze how and to what degree multinational companies organize and operate their supply chains in accordance with the strategic resource of knowledge in their multinational management, and what kind of influence knowledge oriented global supply chain management has on the management performance of multinational corporations. For this purpose, the current research proposed a measurement model to provide specific shape to the concept of knowledge oriented global supply chain management by adopting the knowledge creation process proposed by Nonaka (1994), and conducted an empirical analysis of what kind of impact the knowledge management system and the knowledge creation process of companies have on the performance of their global supply chain management. The result of the empirical analysis of 113 multinational companies verified the validity and reliability of the measurement model proposed in this study. In addition, the comparative study of the sampled companies by grouping them according to the level of knowledge orientation in global supply chain management indicated that the enterprises that effectively manage the knowledge created within the global supply chain presented overall superiority on the performance of global supply chain management.

Supply chain management(SCM) has become an integral part in manufacturing management. And it is often discussed that the actual advantages of supply chain management can be exploited by its integrative management approach. Very often in this context scholars refer to the need of integrating the supply chain. However few examples of truly integrated supply chains are witnessed and it is not always clear what integration implies and how it is implemented. In this paper, it is empirically attempted to analyze the integrated supply chain management practices in a strategic perspective. Using the data gathered from Japanese manufacturers, a taxonomy of the SCM integration strategy is developed and the characteristics of each company group are investigated with a viewpoint of integrated supply chain management initiatives. Furthermore the relationships between the taxonomy and the manufacturing strategy process are also examined.

The paper examines the determinants factor and business performance of global supply chain management. Partnership and process innovation were used as proxy for the characteristics of determinants factor of global supply chain management. Agility of business performance was used as proxy for the business performance of global supply chain management. Based on the analysis of sixty eight global supply chain management cases in Oil and Chemical Industry, the following results were found. Firstly, it was found that the process partnership of determinants factor affects agility of improved business performance. Secondly, process innovation of determinants factor was not improved more agility of improved business performance. However, there were several limitations such as characteristics of process innovation and partnership, etc.

Coordination between supply chain partners is viewed critical to effective supply chain management. In many situations such as mutual investments or developing infrastructures for their operations related with each other, the coordination issue arises. Depending on the bargaining power balance between them, it is determined who will be able to exert more influence in making decisions related with such coordination. We consider two cases of the decision-making structure in the context of a simple supply chain consisting of two players, i.e., (1) the first case in which a supply chain partner dominates the decision-making process and the other passively follows the dominant player's decision, and (2) the other case in which the two players share the decision-making process equally. We examine which of the cases is better for the companies and where comes the value of the better case. To answer the research questions, we set up an optimal control theory model and derive an analytical solution. The analysis outcome indicates that the shared decision-making in general produces better results for both companies in the supply chain, and the value of the shared decision-making comes from more effective resource utilization than the dominated case.

An era of smart manufacturing is coming through the rapid development of information and communication technology. As a result, many companies have begun to utilize a variety of hardware and software for the efficient business of the manufacturing process. At this time, the hardware and software used are supplied through manufacturing and distribution processes. These supply processes are exposed to a variety of security threats. As the recent cases of supply chain attacks have increased, foreign countries are establishing supply chain management systems and managing supply chain risks. In Korea, on the other hand, there was research on supply chain risk management in some fields. In this paper, we emphasizes the necessity of supply chain risk management through supply chain attack cases. In addition, we analyze trends of foreign supply chain management system and explains the necessity of domestic supply chain security strategy.

This paper develops a model to predict the adoption and level of usage of network technology in a two-level supply chain with buyer-supplier relationships. A firm's adoption of a new technology depends not only on its own beliefs of the new technology's costs and benefits, but also on the adoption decisions of other firms in the supply chain. A model first analyzes an individual supplier's decision about a new technology adoption considering with multiple suppliers and buyers. Individual suppliers' decisions are aggregated with a population model to project how new technology diffuses across the supply chain and examine the pattern of diffusion process. This study found that as more firms adopt in initial periods, the total amount of information to the potential adopters in the population increases, and then the number of firms persuaded by the information increases as the process moves up the distribution of adoption process. We consider three factors influencing the diffusion speed of the new technology in a supply chain network : mean benefits, cost sharing, and information provision. This study examines how such factors affect the reduction of threshold levels, which implies that reductions in threshold levels have an aggregate effect by accelerating the rate of adoption. In particular, we explore relationship factors available in practice in a buyer-supplier relationship and numerically examines how these relationship factors contribute to increase the diffusion speed of the technology in a two-level supply chain.

As productions and deliveries of multiple products to multiple marketplaces have been increasingly popular, supply chain flexibility, which refers to an ability to deal with demand and capacity uncertainty, becomes an important issue in supply chain management. However, logistics costs have been largely neglected in the literature on supply chain flexibility structure. In this paper, we propose mathematical models to investigate the impact of the logistics costs on the optimal flexibility structure. We also conduct a simulation study and observe that logistics costs have a significant impact on the decision on supply chain flexibility structure. Such conclusion is also supported by the case study of a global car manufacturer, Honda Motors.

The purpose of this study is that analyzing the causal relationship between Infra, Process and Performance of companies which are executing the Supply Chain Quality Management(SCQM) with their subcontractors and partners. Korean Standards Association(KSA) provides the Supply Chain Quality Management Model and Quality Collaboration Index for 4 years, but a few study has investigated the critical variables and their causal relationship to organizational performance. Therefore we examine the SCQM model and related index and choose the quality, human resource and risk management processes for identifying the path to organizational performance. In addition, exploratory factor analysis is conducted for figuring out the major factors among the 3 processes. Structural Equation Model are successively used for determining which characteristics of the infra and processes are the most critical variables to performance. The data was collected from KSA and composed of 52 companies and 346 their partners. The result shows that risk management process has no significant effect on the organizational performance and pre-production process collaboration.
