In today's changing environment where the product life-cycle is becoming shorter, enterprises are forced to introduce new products as rapidly as possible and to score a success in a market. It is important to manage suppliers who supply parts of the new products to satisfy variable demands. We suggest performance measures of flexibility for suppliers in new products environments. We analyzed the measures from literatures, SCOR (Supply Chain Operations Reference) model and several scorecards. A simulation study was made with the measures in order to understand adaptability of a supply chain. It could help a manufacturer make a decision of purchasing and find a bottleneck supplier.

As globalization has been progressed, companies faced a situation in which it was difficult to secure global competitiveness only with their internal management systems. To overcome this, Supply Chain Management (SCM) emerged, which optimizes the whole supply chain process from suppliers to demand companies. In this study, it was analyzed that the effects of customer integration among the integration factors of SCM, and market orientation among the strategic orientations on management performances such as non-financial performance and financial performance through a mediating role of flexibility. At this time, it was analyzed whether CEO's support has a moderating effect on the influence of the market orientation. As a result of analysis, the customer integration was found to have an indirect effect on the non-financial performance and the financial performance through the flexibility. The market orientation was found to have a direct effect on the non-financial performance and at the same time, indirectly affected it through the flexibility. In addition, it was shown that more the level of CEO's support, higher the influence of the market orientation. This moderating effect had an indirect effect on the financial performance. Based on the above findings, various implications for improving management performance were proposed. This study suggests that investments in computerization such as ERP and smart factories can improve supply chain management performance and ultimately improve customer satisfaction and financial performance.

EPC 산업군에 속하는 기업들의 주요 업무에 대한 아웃소싱비율이 급격히 높아짐에 따라 프로젝트 공급망의 성격과 협력업체와의 협업구조도 더욱 복잡해져 가고 있다. 1, 2차 또는 그 이하 협력업체의 복잡한 공급망에의 참여는 지속적인 통합노력을 필요로 한다. 본 연구는 2차 협력업체를 중심으로 기업 성과와 거래기업에 대한 관계만족도에 영향을 미치는 선행요인 분석에 초점을 둔다. 네트워크 배태성, 협업, 정보공유 및 신축성 등을 선행요인으로 설정하고, 프로젝트 공급망에의 참여실적이 있는 2차 협력업체들로부터 설문조사를 실시하여 통계적 가설을 검증하였다. 분석결과, 2차 협력업체의 공급망 주도기업과 1차 협력업체와의 협업은 성과와 만족도에 유의한 영향을 미치며, 정보공유와 신축성은 네트워크 배태성과 협업에 긍정적 영향을 미친다는 것을 확인할 수 있었다. 또한 협업에 의한 역량제고는 네트워크 배태성에 의해서도 상당한 영향을 받는다는 결과도 도출하였다.

In spite of the increase of the necessity and the interest regarding the SCM in practical business, it is difficult to judge the whole situation of the SCM because the research remain fragmentary as compared with the huge and complicated concept of the SCM. So this study defines dimension of SCM practice and measurements of SCM performance. Through an extensive literature review, the study Identifies seven dimension of SCM practice(partnership, usage of IT tools, information sharing and information quality), five measurements of SCM performance(supply chain flexibility, supply chain integration, customer responsiveness, supplier performance, and partner relationship). Five hypotheses were formulated for the relationship between SCM practice and SCM performance. The important relationships to be tested include ; (1) the direct impact of usage of IT tools on the partnership (2) the direct impact of partnership on the information sharing and information quality (3) the direct impact of SCM practice on the performance of SCM, (4) A moderating effect of top management support on the relationship between SCM practice and SCM performance.

The aim of synchronization of production and transportation planning in the supply chain is to increase the flexibility and to decrease various costs. The suggested model in this study synchronizes the timing to supply to a downstream manufacturer directly after production and to be consumed in a downstream manufacturer right after receipt. This model deals with the frequent delivery in small amount which is a new trend of the transportation not governed the economy of scale principle. Moreover, various types of transportation governed by the economy of scale principle or not are considered. Then, the two-phase mathematical model is suggested to obtain optimal job sequence and production quantity for each tasks. But, it is difficult to gain optimal solutions if there is a transportation governed by the economy of scale principle in the supply chain, or the size of the problem is increased. Thus, heuristic algorithms based on simulated annealing and genetic algorithm are suggested to find good solutions in the reasonable time.

Globalization of market and diversification of customers' needs make enterprises to collaboration of participants in supply chain. To establish collaboration, supply chain must have the flexibility and reconfigurability, which are supported by fractal based supply chain management (FrSCM). In this paper, base on the FrSCM, formulation of trust model among the enterprises in the supply chain, and development of profit sharing strategies in the supply chain based on the trust model are investigated. To evaluate trust model, generation of enterprise's goal and its description, extraction and systematic composition of trust factors and trust evaluation are investigated. Based on the developed model, we developed the fuzzy inference engine to evaluate the trust value in terms of numerical value. And then revenue sharing strategies are developed based on the fractal concept and trust model for the collaborative SCM. The fractal concept is used to obtain the optimal production and transportation plans. In addition, the trust model will be integrated into the RS model. In such an RS model, the supply chain will obtain the maximum total profit and profit of each participant depends on its trust value.

As the global market becomes more competitive, manufacturing industries face relentless pressure caused by a growing tendency of greater varieties of products, shorter manufacturing cycles and more sophisticated customer requirements. Efficient and effective supplier selection and order allocation decisions are, therefore, important decisions for a manufacturer to ensure stable material flows in a highly competitive supply chain, in particular, when customers are willing to accept products with less desirable product attributes (e.g., color, delivery date) for economic reasons. This paper attempts to solve optimally the challenging problem of supplier selection and order allocation, taking into consideration the customer flexibility for a manufacturer producing multi-products to satisfy the customers' demands in a multi period planning horizon. A new mixed integer programming model is developed to describe the behavior of the supply chain. The objective is to maximize the manufacturer's total profit subject to various operating constraints of the supply chain. Due to the complexity and non-deterministic polynomial-time (NP)-hard nature of the problem, an improved genetic approach is proposed to solve the problem optimally. This approach differs from a canonical genetic algorithm in three aspects: a new selection method to reduce the chance of premature convergence and two problem-specific repair heuristics to guarantee feasibility of the solutions. The results of applying the proposed approach to solve a set of randomly generated test problems clearly demonstrate its excellent performance. When compared with applying the canonical genetic algorithm to locate optimal solutions, the average improvement in the solution quality amounts to as high as ten percent.
