공급사슬의 구조가 복잡해지고 고객의 수요가 다양해지면서 공급사슬에서의 물류기능은 점점 중요시되고 있다. 지금까지의 생산자는 전체 물류의 60% 이상을 제 3자 물류 업체를 통하여 수행하였다. 택배 시스템은 자신의 서비스 능력과 상호보완관계에 있는 여타 서비스 제공업체와 연계하여 공급사슬 효율화를 효과적으로 지원할 수 있는 체계가 필요한데 공급사슬 전체에 대한 물류서비스를 여러 업체로부터 개별적으로 외부 위탁하는 경우보다 한 번의 계약으로 통합된 물류서비스를 제공받기를 원하는 경우가 많아지고 있다. 이에 협력택배시스템의 추진이 필요하고 있다. 타사에의 정보 누출을 꺼려 아직은 인식이 부족한 상황이나 보다 효율적이고 저렴한 물류비용을 위해서는 앞으로 제조업과의 다 자간 전략적 제휴는 필수적인 상황으로 전개될 것이다. 이에 현 3PL의 문제점을 살펴보고 제조업과의 협력 방안을 살펴보기로 하겠다.

Confronted with serious problems in nurturing IT engineers such as a mismatch in supply and demand of IT workers, shortage of globally competitive IT professionals, and insufficient education and training of university graduates, the Ministry of Information and Communication has decided to adopt a new approach in national IT engineering education, based on supply chain management (SCM) in manufacturing. SCM weighs improving competitiveness of the supply chain as a whole via a long-term commitment to supply chain relationships and a cooperative, integrated approach to business processes. These benefits of SCM are believed to provide useful insight into a more effective IT education and industry orientation. On the basis of the SCM literature, a framework for industry-oriented practical IT higher education is designed, and then applied in the field of computer-software engineering in Korea.

Recently the increased attention pays on the processing of multiple, relatively low quantity, high value-added products resulted in adoption of batch process in the chemical process industry such as pharmaceuticals, polymers, bio-chemicals and foods. As there are more possibilities of the improvement of operations in batch process than continuous processes, a lot of effort has been made to enhance the productivity and operability of batch processes. But the chemical process industry faces a range of uncertainties factors such as demands for products, prices of product, lead time for the supply of raw materials and in the production, and the distribution of product. And global competition has made it imperative for the process industries to manage their supply chains optimally. Supply chain management aims to integrate plants with their supplier and customers so that they can be managed as a single entity and coordinate all input/output flows (of materials, information) so that products are produced and distributed in the right quantities, to the right locations, and at the right time.The objective of this study is to solve the purchase, distribution, production planning and scheduling problem, which minimizes the total costs of production, inventory, and transportation under uncertainty. And development of SCM model in chemical industry including batch mode operations. Through that, the enterprise can respond to uncertainty. Also integrated process optimal planning and scheduling model for manufacturing supply chain. The result shows that, the advantage of supply chain integration are quality matters seen by customers and suppliers, order schedules, flexibility, cost reduction, and increase in sales and profits. Also, an integration of supply chain (production and distribution system) generates significant savings by trading off the costs associated with the whole, rather than minimizing supply chain costs separately.

Supply Chain Management(SCM) is getting important, because size of the company is getting bigger and the kinds of product are various. In the case of manufacturing corporation, for the optimization of SCM, we have to make production and distribution plan by considering the various fluctuation in the aspect of integration. In this paper, first, It proposed the reasonable operational way of the SCM about when the customer's demanding is various and demanding expectation fluctuates in capacity standardization of producer stage. Second, the paper proposed the management way for demanding by considering confirmed demanding information, related inventory expense and demanding shortage expense when we make production and distribution plan. The paper applied the genetic algorithm proved for current usefulness. it proposed the optimal operational way for SCM by dividing into 2 ways for dealing with the duration of confirmed demanding information and various fluctuation.

This study reviews previous studies about the effects of RFID capabilities on strategic supply chain competence and business performance in the Chinese context. This study introduces a new perspective that measures the degree to which RFID capability levels contribute to business performance. Such an assumption is based on the fact that companies build their own capabilities through RFID capabilities and that these capabilities provide a competitive advantage for enterprises. Data on all sorts of logistics, distribution, and manufacturing companies that introduced RFID system in China were collected for data analysis. This study analyzes the structural equation modeling using Smart-PLS 2.0 program. This study confirms that internal reliability, convergent validity, and discriminant validity are satisfied. The hypothesis test result on the relationship between RFID capacity and strategic supply chain competence and strategic supply chain competence and company results is partially adopted. This study aids in establishing a RFID system construction strategy to enhance supply chain competence by suggesting guidelines for the successful introduction of RFID system through identifying the causal relationship between RFID capacity and strategic supply chain competence. This study also suggests the influence of RFID competency on visibility, agility, flexibility, and collaborations.

This study analyzed both the effect small and medium-sized suppliers' SCM capacity on the performance and how the moderating effect of demand uncertainty as an environmental factor affects this relation. The study is based on the data collected from the survey of small and medium-sized suppliers operating in electronics, metal, machinery, automobile, and textile. It analyzed the results of survey targeting suppliers of these areas by using structure equation modeling. According to the analyzed result, the relation capital of small and medium-sized supplier affects the performance, but there is no relation between coordination capability and the performance. In case of the moderating effect of demand uncertainty, while there is a positive moderating effect of demand uncertainty between relation capital and performance, there is no any moderating effect between coordination capability and performance. It turns out that the relation capital keep having a positive effect on the performance even if there is a demand uncertainty.

고객 만족과 납기 충족율을 최대화하기 위하여, 정확하고 실용적인 납기회답 시스템(ATP)은 매우 중요한 역할을 한다. 그러나 복잡한 공급사슬관리 환경 하에서 조달, 제조, 분배 등을 모두 고려한 정확한 ATP 수량 할당은 매우 어려운 업무이고, 때문에 많은 연구들이 이루어져 왔다. 지금까지 기존의 선행 연구에서 시도되었던 ATP 모형들은 공통적으로 정수배의 시간 단위만 고려해 왔고, 이는 실제 산업 현장의 ATP 프로세스를 정확하게 반영하지 못하고 있는 비현실적인 가정이라 할 수 있다. 본 논문에서는 SCM을 위하여 비정수 타임 랙을 사용한 ATP 시스템을 고려한다. 기존 연구들에서 이산형의 무리한 가정으로 표현되어 왔던 시간 단위를 동적 생산 함수(dynamic production function) 개념을 통하여 비음의 실수 범위에서의 자유롭게 나누어 고려할 수 있도록 하였다. 이를 통하여 기존 ATP 연구들의 무리한 가정을 제거하였으며, 보다 더 현실에 가까운 ATP 모델을 제안한다. 본 논문에서는 특히 공급 사슬(Supply Chain) 전체의 재고와 생산, 운송을 모두 고려하며 고객 주문에 대응하는 통합 ATP 시스템을 설계하였고, 기존 연구들이 미처 고려하지 못한 시간 흐름의 연속성에 중점을 두고 선형 계획(LP) 문제의 형태로 비정수 타임랙(non-integer time lag)을 갖는 ATP 시스템을 모델링하였다.

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.
