디지털 트랜스포메이션(Digital Transformation)으로 인해 소프트웨어에 대한 의존성이 강화되면서 소프트웨어 공급망의 역할이 커지고 있다. 그러나 안전한 소프트웨어 개발 및 이용을 위한 소프트웨어 공급망 보안 관리는 사실상 어려운 실정이다. 공급망이 복잡해질수록 공급망 공격의 유형은 다각화되는 반면 공급망을 구성하는 공급업체 및 구성요소에 대한 식별 및 취약점 분석은 어려워지기 때문이다. 이에 저자는 국내외 소프트웨어 공급망 보안 관리를 위한 기술 동향에 대한 조사 분석을 수행하고 이를 기반으로 향후 적용할 수 있는 공급망 보안 관리 체계의 발전 방향에 대해 작성하였다.

This paper proposes a new concept of inter-organizational systems (IOS) visibility, considering the key role of IOS in IT-enabled supply chain (SC) cooperation. Further, antecedents and consequences IOS visibility have been studied. Antecedents of IOS visibility are identified from the two conflicting theories of inter-organizational relationships, i.e., RDT(resource dependence theory) and RV(relational view). Investigating SC cooperation from the perspectives of both partners (buyers and suppliers) is important, especially when channel partners depend on each other and when asymmetries in IOS visibility can exist. Hence, this study attempts to accommodate both partners' perspectives in IOS visibility and to look into the consequences of IOS visibility from each participant's perspective.

Recently, firms confront to rapid environmental changes due to scientific development and demand change. Firms are trying to improve supply chain capability to react these environmental changes. Being in these improvement processes, it is important to collaborate with other partners in the supply chain. Firms have tried to outsource their in-house activity to other partners and have eliminated wasteful factors in their process and the supply chain is getting leaner. This study investigates the effect of waste factor degree on supply chain performance under external risks. Test results in this paper show that waste level has negative relationship with supply chain performance. The effect of waste level on the supply chain performance is influenced by external risk. As waste level increases, risk has moderating effect between waste level and supply chain performance. That means it is important to focus on utilization, productivity or integration properly for managing the external risk in order to improve the supply chain performance.

Recently, many firms have been more interested in how the competitiveness of the supply chain can be enhanced, rather than that of the respective company. The purpose of this study is not only to investigate the relationships among the trust between companies, the supply chain integration, and the supply chain performance, but also to demonstrate how the firm size and the absorptive capacity can moderate these relationships. To conduct the hypothesis test including the causal relations between two factors and the moderating effects, 111 data were collected through a survey. As a result, the supply chain performance was positively affected by the supply chain integration as well as the trust between the companies. In addition, the trust had a significant effect on the supply chain performance. The result of the moderating effect of firm size indicates that, compared with a larger group, a smaller group has a stronger relationship between the trust and the supply chain performance, while the relationship between the supply chain integration and the supply chain performance is much stronger in the large group than the small group. As for the moderating effect of absorptive capacity, a higher absorptive group has stronger relationships between the trust and supply chain integration, and supply chain integration and supply chain performance than a lower absorptive group. The findings would provide significant implications for supply chain partners with different sizes and absorptive capacity.

This study was conducted to empirically examine the impact of fit between project radicalness and innovativeness of the supply chain on the degree of supply chain integration. In order to test the research hypotheses, a survey was employed. The results show that the degree of supply chain integration varies on the fit between project radicalness and innovativeness of the supply chain. Specifically, when a supply chain consists of two morphogenetic organizations and the supply chain integration project is radical, we see very highly integrated supply chain. We also find high-level integration of supply chain when project is radical even though both a morphogenetic and a homeostatic organization compose a supply chain. However, we find opposite result, which is low integration, if a project is incremental rather than radical and a supply chain is composed of same types of the organizations mentioned above. Interestingly, degree of integration seems to be always low when a supply chain is composed of two homeostatic organizations, regardless of project radicalness. With these findings, this study concludes that a project whose radicalness is match with the supply chain's innovativeness should be chosen for successful supply chain integration.

This study explores the relationship among perceived uncertainty, transaction characteristics, supplier capability, and supply chain performance through theoretical review in the context of increasing uncertainty such as COVID-19 in the supply chain. Based on comprehensive literature review, it was concluded that transaction characteristics and supplier capability affect perceived uncertainty, and supply chain performance can be affected by perceived uncertainty. These findings are meaningful in that we can estimate how to reduce uncertainty of the supply chain under the same pandemic situation.

현대 기업 경영환경의 가장 큰 변화는 개개의 기업들이 기업전체의 효율성과 이익의 향상을 위해서 공급망 (Supply Chain)에 대하여 많은 관심을 기울이기 시작했다는 것이다. 여기서 공급망이란 원료의 조달부터, 중간재로의 가공 및 유통, 최종제품의 생산 및 배송까지의 기능을 수행하기 위한 설비와 유통 채널의 네트워크를 말하며, 모든 기업들은 원자재에서 최종소비자의 형태로 공급망에 참여한다, 결국 공급망의 형태는 산업과 기업에 따라서 매우 복잡하고 다양할 수밖에 없는데, 원재료의 수급에서 고객에게 제품을 전달하는 자원과 정보등 일련의 흐름전체를 경쟁력 있는 업무의 흐름으로 관리하려는 관리 시스템이 공급망 관리(SCM :Supply Chain Management )인 것이다. 기업들의 공급망 관리에 대한 관심이 증대하는 반면에 고객 수요패턴의 불확실성이나 급변하는 기업환경 등 여러 외부 입력 값들의 변화에 따라 효율적인 공급망 구성을 위한 연구는 부족한 실정이다. 이러한 문제를 해결하기 위해 최근 시뮬레이션을 적용한 공급망 시뮬레이터(SCS : Supply Chain Simulator )에 많은 관심이 집중되고 있다. 본 연구에서는 SCS 의 일종인 Arena Professional Edition과 공급망 관리의 성과를 측정하고 개선분야를 직접적으로 파악할 수 있는 SCOR (Supply Chain Operations Reference Model)을 이용하여 제조기업의 효율적인 SCM 의사결정에 대해서 알아보고자 한다.

Notwithstanding the big potential benefits from interorganizational information systems (IOS), not very many companies have realized these benefits. In an attempt to explain this phenomenon, this study proposes a new construct of IOS asymmetry which refers to the asymmetry in information transparency between supply chain (SC) partners. When there is IOS asymmetry in SC relationships, IOS may not facilitate seamless information exchange among SC partners. Instead, IOS asymmetry may result in SC inefficiencies due to a lack of information sharing. The objective of this study is to empirically investigate whether IOS asymmetry exists in practice and whether it influences SC performance negatively. The data was collected from 130 matched pairs of upstream SC partners in manufacturing industries. The results show that IOS asymmetry indeed decreases overall SC performance. Also, the relationship between IOS asymmetry and SC performance is strengthened under the conditions of high environmental uncertainty.

This research is an application of game theory to developing the supplier selection and demand allocation mechanism, which are the essential and major research areas of supply chain planning and operation. In this research, the most popular and widely accepted mechanism, the progressive reverse auction is analyzed and compared with the other game theoretic approach, Kalai-Smorodinsky Bargaining Solution in the viewpoint of holistic efficiency of supply chain operation. To logically and exquisitely compare the efficiencies, a heuristic algorithm based on Genetic Algorithm is devised to find the other optimal demand allocation plan. A well known metric, profit-cost ratio, as well as profit functions for both suppliers and buyer has been designed for evaluating the overall profitability of supply chain. The experimental results with synthesis data and supply chain model which were made to mimic practical supply chain are illustrated and analyzed to show how the proposed approach can enhance the profitability of supply chain planning. Based on the result, it can be said that the proposed mechanism using bargainging solution mayguarantee the better profitability for the whole supply chin including both suppliers and buyer, even though quite small portion of buyer's profitability should be sacrified.
