본 연구에서는 조립산업의 공급망(Supply chain)에서의 발생할 수 있는 공급붕괴(Supply disruption)를 고려한 공급망 네트워크(Supply chain network: SCN) 모델이 제안된다. 공급붕괴를 위해 공급자 붕괴(Supplier disruption)와 경로 붕괴(Route disruption)가 함께 SCN 모델에서 고려되며, 이러한 두 가지의 붕괴 현상을 함께 고려한 SCN 모델은 유연성(Flexibility)과 효율성(Efficiency)을 성취할 수 있게 된다. SCN 모델은 수리모형으로 표현되며, 혼합유전알고리즘(Proposed hybrid genetic algorithm: pro-HGA) 접근법을 이용해 이행된다. 수치실험에서는 몇몇 상이한 규모를 가진 SCN 모델을 이용해 제안된 pro-HGA 접근법의 수행도와 기존 접근법의 수행도를 비교분석하였으며, 공급자 수와 백업경로(Backup route) 수의 변화를 통한 민감도 분석을 실시하였다. 실험 결과, 제안된 pro-HGA 접근법의 효율성을 입증하였고, SCN 모델의 유연성과 효용성을 검증하였다. 마지막으로 본 연구 수행의 의의 및 향후 개선방향에 대해 논하였다.

본 연구의 목적은 공급사슬유연성(운영유연성, 물류유연성)과 경쟁우위전략(저원가, 고품질, 납기신속성)간의 관계를 실증적으로 규명하는 것이다. 이를 위해 공급사슬유연성(운영유연성, 물류유연성)과 경쟁우위전략(저원가, 고품질, 납기신속성) 간의 관계에 대한 모형을 구축하였다. 관련된 자료를 수집하기 위해 구미에 위치한 제조 기업에 종사하는 종업원들에게 500부의 설문지를 배포하였다. 수집된 자료들은 SPSS 18.0을 사용하여 기술적 분석, 신뢰성 분석, 요인분석, 상관관계분석, 다중회귀분석 등의 통계적 기법을 활용하였다. 연구결과 운영유연성은 저원가, 고품질전략에 긍정적인 영향을 미치는 것으로 확인되었으며, 물류유연성은 납기신속성 전략에 긍정적인 영향을 미치나, 운영 유연성은 납기신속성에, 물류유연성은 저원가, 고품질 전략에 유의한 영향을 미치지 못하는 것으로 확인되었다. 따라서 기업은 적용하는 공급사슬유연성과 경쟁우위전략과 적절한 조화를 통해 기업전략을 극대화 할 수 있을 것으로 기대된다.

This paper examined the supply chain management partnerships factors and business performance in textile industry. To build a global network, we should consider the following critical factors such as lead-time reduction, information sharing, and inventory management. The purpose of this study is to focus on QR (Quick Response) of SCM in textile industries to clarify which of the SCM factors contribute to business performance for the SCM firms. Based on the analysis of eighth-six cases, the following results were found. First, partnerships factors of supply chain management have a positively significant influence on responsiveness of supply chain management. Second, partnerships factors of supply chain management have a positively significant influence on flexibility of supply chain management. This study suggests that partnerships are main factors for the business performance. Especially, our empirical evidence shows that capacity of firms practicing SCM, information techniques, and partnerships make the firms' business performance more responsive and flexible.

As the business environment becomes more rapid and unpredictable change, greater diversity, increased complexity, and intensified competitive pressures, supply chain risk management has been growing attention over the past several decades. However, little of known about how absorptive capacity can mitigate supply chain risk for improving operational performance despite its important role in responding to supply chain risk. Therefore, we aim to examine the role of organizational-level absorptive capacity on operational performance, and further identify how the interplay of individual-level and organizational-level absorptive capacity results in operational performance. Our results represent not only direct but also indirect effects of supply chain risk on operational performance, mediated by organizational-level absorptive capacity. Furthermore, this study reveals that individual-level absorptive capacity enhances the effect of organizational-level absorptive capacity on operational performance.

첨단산업의 기업들은 환경의 변화에 효과적으로 대응하는 것을 기업 성패에 중요한 요인으로 여기고 있다. 하지만 첨단산업의 환경 동태성이 공급체인 구성원 간 관계 결속에 미치는 영향에 관한 연구가 부족하여, 환경 변화에 효과적인 대응을 어렵게 하고 있다. 본 연구는 첨단산업에서 환경 동태성이 공급체인의 결속에 영향을 미치는 메커니즘에 대해 규명하고 있다. 좀 더 구체적으로 말하면, 첫째, 첨단산업의 고객, 경쟁, 기술 동태성이 공급체인의 결속에 어떠한 영향을 미치는지, 둘째, 공급체인의 유연성과 의존성이 이러한 영향에 어떠한 조절효과를 가지는 지 실증하고 있다. 구조방정식 모형에 의한 가설검정 결과 첨단산업의 고객 동태성은 공급체인의 결속을 약화시켰지만 경쟁 동태성은 강화시키는 역할을 하였다. 한편 유연성과 의존성은 고객과 경쟁 동태성에 유의적인 조절 효과를 가졌다.

Firms have reexamined and restructured their supply chain based on a long-term and partnership perspective as a firm's competitive advantage increasingly relies on its supply chain capability. A number of scholar works has provided evidence to support the positive effects of supply chain collaboration; however, the relationship between collaboration and performance is still inconclusive. This study refuses to have blinded faith on supply chain collaboration, but rather this paper suggests that the contribution of collaboration to supply chain performance improvement can be limited and vary along the contextual characteristics of a buyer-supplier relationship. Moreover, we argue that the relationship between supply chain collaboration and performance can be curvilinear. This paper provides and test hypotheses regarding the relationship between supply chain collaboration and performance. By using data of the Manufacturing Panel Survey (MPS), this study empirically validates the hypotheses. Overall, the results of the study support our hypotheses about a limited contribution of supply chain collaboration to manufacturing performance, which is opposite to a conventional expectation. Particularly, the effects of supply chain collaboration differ depending on the dimensions of performance such as customer satisfaction, quality, cost, delivery, and flexibility as well as the dependency in the buyer-supplier relationship. Moreover, the results of the study indicate that supply chain collaboration and performance may have curvilinear relationships in a certain context. Through a comprehensive model and empirical evidence, this study presents a better understanding of supply chain collaboration and provokes an open discussion about the effects of collaboration. This study also provides insightful implications for managers of buyers as well as suppliers who wish to foster stronger supply chain performance via a deep buyer-supplier relationship and collaboration.

본 연구는 하나의 공급자와 하나의 소매자가 구성된 분산화된 공급사슬에서 도매가 계약과 수익공유 계약, 수량유연 계약, 판매환급 계약을 비교·분석한다. 선행 연구의 결과에 따라 공급사슬 조정(coordination)이 이루어지는 각 조정 계약의 모수를 설정하였다. 이들 모수의 조합에 대해 @RISK를 활용하여 시뮬레이션을 수행하고 공급사슬 조정을 이루는 상태 하에서 계약의 성사율과 각 계약에 유리한 참여자를 평가한다. 결과적으로 수량 유연 계약은 소매자 쪽에 가장 유리하고 판매환급 계약은 공급자 쪽에 가장 유리하다. 수익공유 계약은 공급자와 소매자의 이익 재배분에 가장 넓은 범위에서 선택할 수 있어 더 유연하게 사용할 수 있음을 밝혔다.

This research aimed to understand the relationship between comparative superiority elements of the supply chain activities for food supplies in the hotel industry. The samples are obtained from exclusive hotels located in the Seoul area. A statistic package program called SPSS was employed to conduct reliability analysis, factor analysis, t-test, correlation analysis, and multiple regression analysis. Results of a multiple regression analysis between supply chain management and food production strategies were as follows; company's characters and cooperative relations with suppliers had a significant impact on cost while quality was significantly affected by company's characters, information system, cooperative relations with suppliers, and supply chain activities. It was revealed that all factors had a significant impact on flexibility and delivery date.

Purpose: The Covid-19 pandemic has had excessively severe impacts on all the nodes and edges of any supply chain due to changes in consumer behaviours and lockdown restrictions from governments among countries. This article aims to provide a simulating experiment on how a supply chain deals with supply disruption risks by flexibility in the inventory level of each sector as a buffer considering the overall cost to fulfil demand in the market. Research design, data and methodology: Agent-based simulation techniques are used to determine the cost-efficiency and customer waiting time related to varying inventory levels of each member in the supply chain when using inventory buffers. Findings: This study has shown that any sudden changes in the inventory level of each sector are likely to impact the rest of the supply chain. Among all sectors, the wholesaler will be impacted more severely than others. Also, the manufacturing sector is the most suitable node to adjust inventory depending on its manufacturing ability. Conclusion: The findings of the study provide insightful implications for decision-makers to adjust inventory levels and policymakers to maintain manufacturing activities in the context of the pandemic restrictions to deal with the excessive demand and potential supply disruption risks.

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.
