This paper refers to the flow of products from supplier to discount retailers(DRs). Discount retailers prefer frequent delivery of small amount because of limited storage space, while suppliers prefer less frequent delivery of larger amount in order to save transportation cost. In this paper we propose a heuristic algorithm to determine the amount of order and the frequency of delivery which decreases the expected length of stockout. We also evaluate various order policies for Vendor Managed Inventory(VMI) system using simulation with real data.

RFID(Radio Frequency Identification)는 재고의 위치를 쉽게 파악할 수 있고, 적재하는 위치나 장소가 바뀌는 경우에 재고의 현황을 알 수 있다. 많은 정보를 태그에 보관할 수 있어 제품관리가 용이하다. 제품의 이력상태를 바로 알 수 있으며, 열이나 물 등의 이유로 인하여 바코드를 사용할 수 없는 곳이나 공정에서도 사용할 수 있다. RFID는 바코드 시스템의 장점을 포함하고 있고 제품개체에 대한 실시간 파악이 가능하다. 이러한 장점으로 인하여 RFID는 유통 및 생산시스템 사용이 크게 확대될 것이다. RFID를 이용하면 Just In Time 생산을 보다 효율적으로 운영할 수 있다. 본 연구에서는 RFID를 이용하여 간판생산방식의 도입에 적용하는 데 있다.

Big data in the supply chain mainly comes from four aspects. One is the relevant data inevitably generated in the process of product value transfer of enterprises in the supply chain, such as production equipment quality data, planned procurement data, product data, etc; On the other hand, it is derived from the ERP data of various companies in the supply chain; The third is e-commerce data from the customer, and the last is data from external or manually entered data. A third-party data service center analysis and mining the data to predict and control the inventory in the process of supply chain operation. It brings innovation and change of management technology and way of thinking to the whole supply chain in many aspects, and finally achieves the goal of coordinated inventory and zero inventory of the whole supply chain.

생산성 향상, 재고의 최소화, 납기일의 준수, 자원의 최대활용등을 위해 그동안 많은 생산관리 기법이 제시되어 왔으며 그중 GT, MRP, JIT 기법이 가장 많이 사용되고 있다. 각각의 시스템은 모두 장단점을 가지고 있기 때문에 이들 시스템을 혼합하면 상호간의 단점을 보완할 수 있을 것이다. GT 기법은 부품의 유사성을 이용한 기존자료의 검색 및 그룹가공을 통한 생산성 향상에 유용하며, MRP 기법은 기초자료를 이용하여 생산 및 자재계획을 동시에 수립할 수 있기 때문에 계획수립에 유용하며, JIT 기법은 낭비의 제거, 재고의 제로화, 간판을 이용한 현장관리 등을 할 수 있기 때문에 실시단계에 유용하다. 본 연구에서는 GT, MRP, JIT 기법을 비교 분석하고 이를 상호 보완할 수 있는 알고리즘을 개발하여 GT, MRP, JIT 혼합 생산시스템의 모델을 제시하고자 한다.

본 논문에서는 최초 제품의 생산에서부터 최종 소비자에 이르기까지의 전 과정에서 RFID 시스템을 이용하여 조달, 설계, 제조, 보수, 폐기의 각각의 단계별 u-Logistics 설계 및 DB통합을 통한 Integrated u-logistics 설계 방안을 제안한다. 제안한 시스템은 단계별 수집된 정보를 기초로 하여 제품 생산과정부터 소비자에게 전달되기까지의 전체 제품의 life cycle을 한곳에서 관리할 수 있기 때문에 능동적이며, 효과적인 재고 관리, 인력 관리, 수요 예측, 판매 성향 분석 등이 이루어 질수 있다. 이는 단순한 유통과정만을 관리하던 기존의 물류시스템과는 확연한 차이를 보여준다.

Vendor Managed Inventory(VMI) is a distribution channel system where the inventory at the retailer is monitored and managed by the manufacturer or vendor. By pushing the decision making responsibility further up the supply chain and centralizing the replenishment decision, the vendor can help the entire supply chain be more competitive. The purpose of this research is to explore the factors influencing the adoption of VMI by Korean manufacturers. This research proposes the IT readiness, operating cost, and information sharing as antecedents of burden for VMI, and collected the survey responses from the small-to-medium manufacturers. The statistical results indicate that only the operating cost has a significant impact on the adoption of VMI. However it has also been found that the IT readiness and information sharing have a significant effect on the operating cost. Thus indirectly influence the adoption of VMI. As a conclusion, the academic and practical implications of these findings are discussed.

The development history of China's big data is relatively short, and it has only been ten years so far. Although the application level of big data in real life is not high, some achievements have been made in the supply chain. Various kinds of data will be generated in the actual operation of the supply chain. If these data can be effectively classified and used, the "bullwhip effect" of the operation of the supply chain can be also effectively improved. Thus this paper proposes the development of a supply chain collaborative inventory management model and application framework using big data. In this study, we analyzed the supply chain of beer industry, which is the most prominent consumption industry with "bullwhip effect", and further established a big data collaborative inventory management model for the supply chain of beer industry based on system dynamics. We used the Vensim software for simulation and sensitivity test and after appling our model, we found that the inventory fluctuations of the participants in the beer industry supply chain became significantly smaller, which verified the effectiveness of the model. Our study can be also applied to the possible problems of the large data supply chain collaborative inventory management model, and gives certain countermeasures and suggestions.

RFID is rising as a means which recognizes products efficiently and correctly. The use of RFID technology can reduce the expense of excess stocktaking, forgery, labor and improve supply network. RFID technology uses RF to recognize the products. EPC, a small tag, is attached to each product, which includes specific product information. Each EPC is only one and can recognize each product. If EPC tag moves to a specific location, the reader reads the tag, the data of which get to be stored in EPC information service, a data storage system. All services can approach EPC information service through web and whenever users demand services, they are provided with the data they want. This study shows an inventory control system is implemented by EPC information service.
