The POS system has been developing into an co-operational information integration system, enlarging its range of application - from basic data collection to production information, inventory management and customer service. The POS system will increase operation efficiency. It is my suggestion that POS system should be adopted in domestic industries regardless of increasing adoption of the RFID. This paper was made studied of the POS system and the practical use of POS system in order to maximize the efficiency of inventory management for various companies.

To effectively maintain manufacturing collaboration, the development of effective performance measurements for the collaboration is required. Most existing key performance indicators however were developed to measure the performances of internal activities or outsourcing of a company. For that reason, it is necessary to devise new key performance indicators that the partners participating in the collaboration can arrange and compromise with each other to reflect their common goals. In this paper, we propose collaborative Key Performance Indicators(cKPIs), which is used to measure the collaboration work of multiple manufacturing partners on the basis of the Supply Chain Operations Reference(SCOR) model. Also, a modified Sigmoid function is devised as a desirability function to reflect the characteristics of Service Level Agreement(SLA) between two partners. The proposed indicators and the desirability functions can be utilized to perform and maintain the successful collaboration by providing a way to the quantitative measurement.

An RFID system has been widely applied in many areas over the initial SCM application. In the literature enormous RFID applications in healthcare are documented to improve patient safety, patient/provider logistics, and the efficiency of collecting data. Based on the proposed 4-layered RFID system architecture, we introduce a case that implemented an UHF passive RFID-based tracking system in an outpatient clinic. Particularly, we propose a method to process RFID data that contains noise and missing reads. The proposed method for processing unreliable RFID data is capable to locate the tag accurately and provide additional business information. We finally conclude the paper with identifying obstacles and what is necessary to ensure system reliability.

The development of RFID system is increasing rapidly by applying to variety fields recently. Especially, RFID system is used to the focus technology of the supply chain management in distribution field of the supplier. In distribution field, We have to grasp products quickly and correctly, but this has a problem to make an inventory of products in real-time because of products transfer. In this paper, to solve this problems. We grasp the state of inventory in real-time by using EPC-IS network becoming the organizational standard of RFID network. also, We offer an authentation of product service to grasp counterfeits and stolen goods in real-time. Therefore, in this paper, We show to be able to process an authentation of product service and inventory of products in distribution field in real-time.

As the information technology including Internet not only opened the cyber world but also has evolved as a platform that enables a new generation of businesses and remolds the shape of thinking and the rules of supply chain management (SCM). By using the Theory of Constraints, which seems simple but robust to review the traditional SCM context, the paper proposes a conceptual framework to handle the SCM issues. From the strategic perspective, this paper focuses on three policy constraints: supplier-manufacturer oriented constraints, manufacturer-distributor oriented constraints, and supply chain oriented constraints. To optimize the throughput and sustain the competitiveness of supply chain members in the dynamic business environment, the companies should utilize the potential competency of information technology and consistently perform the activities of removing and/or reinforcing the constraints.

물류/택배업계의 공급사슬관리에서 차량에 의한 고객의 요구 서비스 시간대 만족은 고객의 재고수준을 낮추고 또한 서비스 수준의 향상에 매우 중요한 제약조건이다. 최근에 소개된 메타휴리스틱인 개미해법(Ant Colony Optimization: ACO)은 NP-hard 문제의 해공간 탐색에 있어서 상당한 장점을 가지고 있으나, 시간대 제약이 있는 차량경로문제(Vehicle Routing Problems with Time Windows: VRPTW)에 대한 적용은 아주 미비한 실정이다. 따라서, 본 연구에서는 ACO 를 VRPTW에 적용하여 최선의 차량경로 해를 구하기 위한 여러 변형을 제시하고, 이들의 영향을 다양한 실험문제를 이용하여 분석하고자 한다. 계산실험 결과, 기본 ACO 에 여러 설계 요소들을 추가함에 따라 계산시간이 다소 증가하지만 보다 우수한 차량경로 해를 구할 수 있었다.

Supply Chain Management is a process-oriented concept, integrated approach to procuring, producing, and delivering products and services to customers. Supply Chain Management covers the management of material, information, and funds flows. A strategic supply chain management produces for value maker and the ultimate customer. One aim of this paper is to determine the effect of contract parameters on the quality of the end product of the supplier-producer chain. The supply chain management is viewed as a single entity rather fragmented. This research constructed model the relationship of supply chain management to quality management. The questionnaire were tested with survey of supplier's employee and the result were analyzed using SEM(Structural Equation Model). As a result, Quality performance positively depends on the communication, coordination, and process management between the supplier and the producer.

Third party logistics research is searching for increasing its logistics efficiency of organization. Perspective of resource-based theory, this study is to reveal the exploratory relation between integrated capabilities, organzaiton knowledge, and service performance. To develop the relational model, this study conducted a theoretical survey on Shang(2009)'s 3PL service providers research model and Synder & Cumming(1998)'s learning of organization knowledge. According to the result of correlation analysis, Integrated organization knowledge is positively correlated with service diversity advantage (correlation coefficient= .670, p-value= .000) and service quality advantage (correlation coefficient= .575, p-value= .000). The thesis argued that Korean companies try to apply integrated organization abilities and service performance for cutting their export expense.

This study addresses strategic issues related to the question of" how can a supply chain become more competivity\ulcorner" We examine several cases of manufacturing supply chains. Results show that each constituent firm is required to maintain different manufacturing capabilities and to play different roles by its position (up/mid/down-stream) in a chain. Furthermore, there are patterns of required capabilities by the positions in a chain. These findings imply that the "position in a chain" should be treated as one of the strategic factors when discussing the buyer-seller relationship. It is also shown that different action programs are required for building different manufacturing capabilities of individual firms in a supply chain. Additionally, we argue that some programs need to be done simultaneously, by all the members of the chain, while some need to be carried out by only a small group or an individual firm. Finally, we propose a direction for a theoretical framework for analyzing supply chain structures and strategies.ures and strategies.

We establish two models -'intermediate' role model and 'infra-structural' role model - to confirm what role the concepts of 'long-term orientation' and 'asset specificity' execute in the context of supply chain management practices affect on SCM performances. We confirm the model's statistical significance with empirical investigation about 167 manufacturing companies in all over the country. As a result, we find that real data fits to 'infra-structural' role model with added paths of concepts and variables rather to 'intermediate' role model. We prove these results with empirical method of confirmatory factor analysis and structural equation model with AMOS program.
