Supply chain management for complex project requires continuous integration activities with the suppliers and subcontractors. This study proposes the firm performances, trust, relational norms, interfirm conflict and cooperation as major research variables, and collected the survey responses from the suppliers and subcontractors having experiences with complex projects. The statistical results indicate that the cooperation and conflict influence the firm performances, and that the inter-firm trust have some impact on the level of cooperation and conflict. It was also found that the inter-firm cooperation is influenced by relational norm. But on the contrary to our expectation, the relational norm has no significant impact on the inter-firm conflict. These findings may offer the significant implications leading to successful implementation of collaborative supply chain management in the context of project engineering area.

External environment of enterprises are rapidly changing brought about mainly by global competition, cost and profitability pressures, and emerging new technology. In particular, frequent change of customer requirements is a tough challenge to manufacturing company. To cope with these challenges, a production planning and scheduling (PP&S) function might be established to provide accountability for both customer service and operational efficiency. PP&S deals with short-term decision making in the production process of whole supply chain. The task of PP&S is to seek a balance between customer orders and limited resources. At present, many PP&S software solutions have been utilized in many enterprises to generate a realistic production plan and schedule efficiently. The aim of this paper is to analyze the PP&S functionalities and its system architecture from the perspective of SCM (Supply Chain Management), and propose the PP&S solution classification framework to facilitate the comparison among various solutions.

Our military's cyberspace is under constant threat from the enemy. These cyber threats are targeted at the information service assets held by the military, and securing the security of the organization's information service assets is critical. However, since Information assets can not be 100% selt-sufficient in any organization as well as the military, acquisition of information assets by the supply chain is an inevitable. Therefor, after reviewing supply chain protection measures to secure the safety of the military supply chain, we proposed a method for securing supply chain companies through the citation of partnership based on the validated trust model.

Through COVID-19, the importance of supply chain management of raw material minerals has been maximized. In particular, supply chain management is important for rare metals, which are difficult to manage demand and supply, in order to secure raw materials for the parts and materials industry that Korea is actively promoting. In this study, a system was established and evaluated to select Critical minerals that need to respond to Korea's industrial structure and global risks by quantifying tangible and intangible risk factors. Global Supply Concentration, Supplying country risk, Policy Social Environment Regulation, Domestic Import Instability, Risk responsiveness, Market Scale, Demand Fluctuation and Economic Importance were evaluated as evaluation indicators. The degree of risk and risk impact were quantitatively measured using the criticality matrix-criticality level. After evaluating 40 types of minerals used in domestic new growth businesses, 15 types of Critical minerals(Li, Pt, Co, V, REE, Mg, Mo, Cr, Ti, W, C, Ni, Al, Mn, Si) in Korea were selected. The results are expected to be used to establish policies to strengthen resource security and to make decisions to form a company's raw material portfolio.

Supply chain management (SCM) has been drawn increasing attention in industries and academia. The attention is mainly due to a need to integrate the multiple activities in a process network from the overall perspective under the constantly varying economic environment. While many researchers have been addressing various issues of SCM, there is not much research explicitly handling the overall dynamics of supply chain entities from PSE literature. In this two-part series paper, it is investigated how the overall supply chain processing times vary in response to the variation of individual entities using Monte Carlo simulation. Instead of figuring out the operation levels of individual entities, the overall operation time called TAT(Turn-Around-Time) is proposed as a performance indicator. An example of 7 entity-supply chain is presented to illustrate the proposed methodology.

As development of the e-commerce, the distributing network for a logistics currency is more complicated. A management of the distributing network (DN) is important factor in distribution planning. The DN can be expressed to distribution center (DC) and the interaction of DC. An internal factor of DC and an external factor to occur by an interaction of DC have many influences on the DN. Therefore, for an efficient DN management plan, analysis of the DN that considered DC and an interaction of DC is required. Until now a study on a viewpoint of supply chain management as resources assignment was performed, but the study on analysis of the distribution network was not performed. This paper propose the distribution network analysis technique that considered DC and an interaction of DC. A proposed technique consists of two steps largely. First of all a DN is expressed with the graph that included an interaction of DC and DC. It uses a reachibility tree, and the following, a DN expressed with a graph is analyzed. Also we presented an example model, and show an usefulness of proposal technique with the analysis of this model.

글로벌 시장환경체제에서 유통구조가 복잡해짐에 따라 제조사에서 유통업체 및 소비자까지 아우르는 전체 공급망에서 제품에 대한 이력추적관리는 투명한 유통구조를 형성시킬 뿐만 아니라 더 나아가 소비자들의 안전에 지대한 영향을 미친다. 세계보건기구(WHO)에 따르면 선진국에서 부정 전문의약품의 유통비중은 전체 의약품의 1% 정도이며 이를 미국에 적용할 경우(2006년 기준), 미국에서 유통된 34억 개 전문의약품 중 3,400만 개의 전문의약품이 가짜일 가능성이 있는 것으로 보고되고 있다. 이로 인해 미국 캘리포니아주에서는 유통망의 투명성과 소비자의 안전을 보고하기 위하여 2D 바코드나 RFID(Radio Frequency IDentification)를 통해 의약품 제조에서 약국까지의 유통과정 계보를 추적할 수 있도록 제약기업에 2015년부터 제품에 시리얼번호를 부착한 이력장치(serialized e-pedigree)를 시행할 예정이다. 따라서 본 연구에서는 국내 외적으로 물류/유통과정에서 제품의 위 변조를 예방하기 위한 e-pedigree에 현황 및 동태를 파악하고 국내 e-pedigree에 대한 방향성을 고찰하는데 그 목적이 있다.

While individual enterprises with different objectives each other within supply chains require a variety of resources to achieve their own seeking goals and performances, it is necessary to form interdependent relationships among the enterprises to secure the resources what they need, as the individual enterprises are supposed to have limitations on such as time, space and cost to secure all the resources. In this process, conflict possibilities rise and opportunistic behaviors increase due to those environmental factors such as unbalanced information among enterprises, limited rationality, pursuit of interests, and risk aversion. Those existing studies on conflicts in the field of supply chains have limitations in that they failed to present specific conflict management strategies based on the conflict types from the perspective of the conflict resolution mechanism as the studies have made only focused on investigating the causes of conflicts and the impact of conflicts on performance. In this study, therefore, it used the TKI model of Kilmann and Thomas(1977) to subdivide the conflict management strategies in the process of transactions within supply chains by enterprises, and looked into the impact on partnership and performance according to each strategy. As the results, it showed that those types of conflict management strategies such as concession type and cooperation type had a positive(+) impact on the relationship commitment as a factor of partnership, and it was identified that the relationship commitment had a positive(+) impact on performance. In other words, it can be considered that the enterprises making use of the concession type & the cooperation type conflict management strategies under the situation of conflict would be able to have a very positive impact on their performances if they can make good relationship commitment such as investments in and efforts for the sustainable relationship along with the conflict management, while recognizing the importance of relationship. The most important meaning of this study lies on in terms of that it would be contributable to strengthening the partnership between enterprises and minimizing the risk of supply chains caused by conflicts through these results from the study.
