The Covid-19 pandemic has had a significant impact on global logistics and supply chains, leading to major discrepancies in logistics performance across countries worldwide. Through an examination of logistics performance index and supply chain tracking data, this study aimed to identify the changes in global supply chains and logistics environments during the pandemic. The analysis of the logistics performance index showed that overall, countries around the world, especially developed nations, showed improvements in metrics such as customs and border management efficiency, the quality of trade and transport infrastructure, capability and quality of logistics services, and cargo tracking abilities. However, the competitive pricing feasibility of international transportation and the on-time delivery frequency of goods saw a decline due to the pandemic's effects. The supply chain tracking data revealed that ports in Asian countries demonstrated high processing efficiency. In contrast, the U.S. and European countries took comparatively more time. Particularly for air cargo, parcels, and express shipments, the U.S. showed relatively longer processing times, leading to logistical delays. In conclusion, during the Covid-19 pandemic, Asian countries maintained relatively high efficiency in their logistics and trade environments. Conversely, the U.S. and some European countries showed delays and decreased efficiency in various metrics. In the future, efforts should be made to address delays and congestion, namely, the deceleration of logistics processes.

Little attention has been given to semiconductor manufacturing in the chemical engineering and process systems engineering perspective in spite of the fact that it consists of numerous chemical processes. This paper particularly investigates the issues in semiconductor manufacturing supply chain management. From the personal industrial experience and research progresses, relevant research and information will be introduced to address the key issues and challenges. Some remarks for future research challenges are made in the end.

Reference modeling for Collaborative Networked Organizations(CNOs) has just started, and Enterprise Architecture Modeling Languages(EAMLs) for CNOs are very few. Lack of reference models makes it difficult for people to communicate with each other and lack of EAMLs also makes it difficult to implement information systems for CNOs. We propose an EAML for CNO called CAML. It supports (1) multi-level modeling based on Model- Driven Architecture of OMG's for expressive power and efficiency of implementations, and (2) multi-focus modeling based on Zachman Framework for completeness of modeling The effectiveness of the CAML is investigated through modeling of a supply chain and execution of change impact analysis.

The trend of business work that is related to supply chain changed into e-business using the electronic document However, the small and medium enterprise organizations still use huge volume of paper document, especially in private sector. Recently, the need for eco-friendly and low cost logistics becomes increasing. For this, it has expanded to exchange or to use e-document rather than the paper or manual processing in supply chain business. Therefore, this paper proposed the electronic access system for supply chain by business process modeling. If it is using the proposed system, it can be saving the exchanged or the scanned document to system, and user can utilize that document on just accessing system whenever they need the document. We believe it might reduce the burden of each organization because they don't need to save large volume data to their system or place. Furthermore, the benefits will effect across the national as well as global.

Recently, the aim of cold storage warehouse is not only to provide preservation of the quality of perishable foods but also to use state-of-the-art information systems to rapidly move products across the cold chain. An RFID (Radio Frequency Identification) is an automatic identification method that detects signals from mobile objects, and tracks and traces movement of the objects. RFID can be used to turn a cold storage warehouses into a real-time system. In this paper, we develop an cold storage management system to support the optimized business processes with RFID system. First of all, business processes in the cold storage warehouse are analyzed. Then design factors which should be considered for incorporating RFID are defined. Design values which set to the design factors can be extracted from using RFID deployment simulator. as a result, the design values make RFID to be efficiently integrated to existing business processes.

최근들어 RFID 기반의 SCM에 대한 연구는 많이 진행되고 있다. 그러나 공급망상에서 이동중인 물류정보의 오류를 동기화하고, 장치기반 인프라의 상태정보를 모니터링하여 활성화해주는 연구와 기술은 아직 미흡하다. "물류정보동기화 기반의 Smart SCM 모델"은 실시간으로 각 물류 거점에 설치된 RFID 인프라 장치 및 물류 프로세스 동기화 현황을 Dashboard를 통하여 모니터링하고, 예외상황 발생시에 다양한 의사결정 지원정보 제공을 통해 즉각적인 상황 조치가 가능한 지능형 공급망 통합관제 서비스 모델이다. 본 연구 모델은 물류국제 표준, RFID관련 국제 표준 규격, EPCIS 표준, SSI 미들웨어 플랫폼을 준용하여 표준화 하므로써 관련 기술 국내 표준 규격을 제시하고자 하였다.

Recently, interests for SRM have been increasing rapidly to automate the whole processes of supply chain from sourcing to procurement and improve the whole efficiency of supply chain by strategically managing the relationship with external partners (suppliers). The national procurement service of Korea is trying to build new paradigms by introducing SRM for improving the competitiveness of national public procurement service. For this, a new assessment model for evaluating and selecting suppliers with fairness and objectivity should be developed. In this paper, we propose a new SRM solution including a model that evaluates and grades of suppliers' capabilities of performing the contracts. We also explain the innovation of national public procurement system through this SRM solution.

The curtain wall engineering of local high-rise buildings consists of many phases such as design, curtain wail design, manufacture, procurement, construction and facility management, each of which also involves many' actors such as architect, curtain wall consultants, manufacturers, contractors, and facility managers. Moreover, the method for controlling the C/W process of each participant is needed. Eliminating wastes and problems existed in the C/W process can be more effective. What is more, it is necessary to improve the efficiency of the current process and to strengthen the competence through application of SCM to the C/W life-cycle. In addition, it is important that a ]ot of information transfer smoothly and share through information system. Therefore, this study aimed to propose the scope of application and the improvement directions in applying Supply Chain Management concept.

IT system in supply chain management(hereafter, SCM) has been regarded as one of competitive advantage to win over competing supply chain. SCM participants rush to adopt IT system to be agile for changing environment. Companies expect the improvement of the process integration over the supply chain, which enhance the overall SCM performance. IT system has been considered to influence on effective communication over the wall of firm boundaries. But, the profitability or the effectiveness of IT investment are controversial. This study try to reemphasize the importance of IT system considering the differences of processes, and the influences on the collaboration of supply chain participants. We want to know the perception level of functional managers for the importances, usages, and contributions of IT system in manufacturing sector. Also, we compare the different perception for collaborative SCM among supplier, buyer, and employees of buyer, and try to understand the context in which the IT investment acceptance occurs. We collected 297 responses(199 from line process and 98 from project process respectively). Results show that the importances, usages, and contributions of IT system are higher in the line process than in the project process.
