Purpose - The study investigates the impact of consignment on the economic performance in the supply chain with three stages. Through the analysis on distinct forms of consignment application, this study intends to answer to the question of how the consignment should be used in the multi-stage supply chain. Research design, data, and methodology - The proposed mathematical model represents the supply chain system with a manufacturer, a wholesaler, and a retailer. Three different forms of consignment application are considered depending on which stages adapt the consignment, and their system profits are compared with the traditional non-consignment system in numerical examples. Results - The numerical examples show that the serial consignment application performs better than any other forms of consignment as well as the non-consignment system. The additional analysis indicates that the system profit is significantly sensitive to the consignment rate. Conclusions - The outcome of this study implies the potential of consignment to improve the system performance even in the multi-stage supply chain system. Meanwhile, each supply chain member's preference to the specific form of consignment application could be different depending on which stage he has. All the supply chain members should jointly determine the appropriate consignment rates to obtain the best system performance.

This study empirically investigated the changes of performance evaluation systems under the environment of supply-chain e-commerce. The objectives of e-commerce include obtaining financial profit, internal innovation through processes integration, learning with information flow, and customer satisfaction through quick response. These objectives are generally consistent with the four evaluation measures of balanced scorecard(BSC). This study, first, demonstrated that perceived environmental uncertainty(PEU) has a significant effect on the adoptions of e-commerce and BSC, and severe competition positively influences the use of e-commerce. With cluster analysis and subgroup analysis, we also showed that under the high adoption levels of e-commerce, the high utilization of BSC can improve the supply-chain performance of a firm. In addition, it was found that the use of e-commerce indirectly and significantly affects supply-chain performance through inter-organizational information flow, and the supply-chain performance of a firm leads to the improvement of organizational performance.

We consider a two-tier supply chain with multiplicative random yield. We focus on the supply chain performance with respect to the control scheme of determining the production lot size. The profit loss due to distributed control is analyzed to give an insight for devising efficient supply contracts.

본 연구는 코로나19 이후 공급사슬 리스크에 대한 주요 이슈와 연구 동향을 살펴보기 위해 해외 및 국내 저널을 바탕으로 키워드 네트워크 분석을 수행하였고, 뉴스와 기사를 대상으로 네트워크 텍스트 분석을 실시하였다. 선행연구에서 상대적으로 부족했던 코로나19 이후에 대한 공급사슬 리스크를 분석한 결과, 코로나19 이후 해외 및 국내 저널, 나아가 뉴스 기사에서 이전 선행연구와는 다른 공급사슬 리스크 회복, 대응 및 민생 등과 같은 연구 동향을 알 수 있었고, 기업에 있어 공급사슬 리스크에 대한 실무적 전략 및 통찰력을 제안할 수 있었다.

In this paper, we consider a multi-factor, multi-cause decision making problem of supply chain. And we show how to measure the operational efficiency of the components in supply chain and also how to improve the efficiency of each component and whole supply chain. As a methodology, the data envelopment analysis (DEA) is adopted to measure the efficiency by considering weight factors such as flexibility, information sharing, logistics level, etc. The proposed algorithm allows whole supply chain to have the improved efficiency rate.

This study explored the impact of interactional justice on supply-chain collaboration and sustainable supply-chain performance. Accordingly, it classified interactional justice of supply-chain management (SCM) into interpersonal and informational justice, and empirically classified the effects of these subordinate concepts on supply-chain collaboration and sustainable supply-chain performance. To this end, 700 questionnaires were distributed, and 201 final valid responses were used for the statistical analysis which revealed the significant positive influence of interpersonal justice on informational justice. This indicates that courtesy, respect, and proper words are important in the relationship between buyers and sellers. Both interpersonal and informational justice had a significant positive relationship with supply-chain collaboration. The results suggest that a fair-trade environment should be cultivated to encourage and facilitate seller-buyer collaboration. Lastly, supply-chain collaboration had a positive influence on sustainable supply-chain performance. This implies that if justice is not perceived in the seller-buyer relationship, collaboration can be hindered, which negatively impacts corporate performance. These findings also helped to understand the importance of interactional justice and to propose a new relationship between interpersonal and informational justice.

본 연구는 에너지기술개발사업의 과제 기획 결과 자료를 활용하여 정부의 기술개발사업의 과제 기획 과정에서 산업분석이 지원 대상 기술 개발 과제 선정에 미치는 영향과 의미를 알아보고, 효과적인 산업분석 방안을 제안하였다. 실증 분석 결과, 기획 과제 선정에서는 R&D 효율성과 R&D 지원 필요성이 감안되고 있는 것으로 분석되어 기획 과제의 선정 과정에서 산업의 요구를 상당히 반영되고 있었다. 그러나 Supply Chain 공백 정도나 Supply Chain 완성 기여도, 그리고 대외수지 개선 기여도는 과제선정에 잘 반영되지 못하였다. 즉, 지속적인 대외 교역 수지 개선과 에너지 산업의 수입 의존적 발전의 개선 필요성이 높음에도 불구하고 기획 과제의 선정 과정에서는 해당 기획 과제가 소속된 Supply Chain의 완성 상태에 대한 고려와 수입 대체 및 수출 산업화에 대한 고려가 부족하였다. 따라서 정부 기술개발사업에서는 R&D 지원이 보다 효율화될 수 있도록 보다 세밀한 산업 분석을 통해 산업의 R&D 수요를 정확히 파악하고 그 R&D 수요를 잘 충족시킬 수 있도록 기술 개발 기획이 이루어질 필요가 있으며, 더욱 체계화된 Supply chain 분석과 활용이 필요한 것으로 나타났다.

Supply Chain Management is the process of planning, implementing and controlling the operations of the supply chain to satisfy customer requirements as efficiently as possible. It spans all movements and storage of raw materials, work-in-process inventory, and finished goods from point-of-origin to point-of-consumption. Korean Standards Association claims the Supply Chain Quality Management(SCQM) as a win-win model of organizations among the supply chains for the best product/service quality to final customers. The SCQM is focused on quality of product/service and will do much for improving manufacturing performance between customer and suppliers. Consulting-teams make every effort to design suitable solution for constructing solutions and improving the performance. This study is to analyze the performance of SCQM consulting, from July of 2007 to June of 2008, and would provide some guidelines to design the optimal consulting models and develop guidebooks.

It is urgently-needed to construct a green supply chain (GSC) from collection of used products through recycling of them to sales of products using the recycled parts. Besides, it is necessary to consider the uncertainty in product demand as a risk in a GSC. This study proposes the optimal operations for a GSC with a retailer and a manufacturer. A retailer pays an incentive for collection of used products from customers and sells a single type of products in a market. A manufacturer produces the products ordered by the retailer, using recyclable parts with acceptable quality and compensates the collection cost of used products as to the recycled parts. This paper discusses the following risk attitudes: risk-neutral attitude, risk-averse attitude, and risk-prone attitude. Using mean-variance analysis, the optimal decisions for product order quantity, collection incentive, and lower limit of quality level, in the decentralized GSC (DGSC) and the integrated GSC (IGSC) are made. DGSC optimizes the utility function of each member. IGSC does that of the whole system. The analysis numerically investigates how (i) risk attitude and (ii) quality of recyclable parts affect the optimal operations. Supply chain coordination between GSC members to shift IGSC from DGSC is discussed.

공급망을 효율적으로 관리하기 위해서는 공급망의 특성과 구조에 대한 이해가 선행되어야 하는데, 이를 위해서는 공급망을 분석할 수 있는 프레임워크가 필요하다. 본 논문에서는 공급망을 관계유형의 관점에서 분석할 수 있는 프레임워크를 제시하고 있다. 이러한 프레임워크를 토대로 공급망 관계 유형을 분석함으로써 공급망 상에 놓여있는 각 주체들의 공급망 수준을 파악할 수 있다. 본 논문에서는 이러한 프레임워크를 항만물류산업에 적용함으로써 우리나라 항만물류산업의 공급망 수준이 어느 정도인지 파악하고 앞으로 발전적인 공급망을 형성하기 위해 고려해야 할 사항들을 도출하였다.
