  • As today's business environment has become more and more competitive, forward as well as backward flows of products among members belonging to a supply chain have been increased. The backward flows of products, which are common in most industries, result from increasing amount of products that are returned, recalled, or need to be repaired. Effective management for these backward flows of products has become an important issue for businesses because of opportunities for simultaneously enhancing profitability and customer satisfaction from returned products. Since third party logistics service providers (3PLs) are playing an important role in reverse logistics operations, the 3PLs should perform two simultaneous logistics operations for a number of different clients who want to improve their logistics operations for both forward and reverse flows. In this case, distribution networks have been independently designed with respect to either forward or backward flows so far. This paper proposes a mixed integer programming model for the design of network integrating both forward and reverse logistics. Since this network design problem belongs to a class of NP-hard problems, we present an efficient heuristic based on Lagrangean relaxation and apply it to numerical examples to test the validity of proposed heuristic.

  • Today, the problem of the logistics rationalization has significant meanings as one of the new strategies for improving the power in the international competition. In order to achieve the logistics rationalization, the enhanced recognition to logistics of each enterprise is essential. However, the complete arrangement of the logistics external environment, that is, logistics infrastructure is also one of the most important matters. In this respect, to rationalize the container logistics, this paper deals with the strategies for strengthening the function of Pusan port which is handling the 95% of the export and import container. Some suggestions for those are as follows : First, the coastal container transportation system must be strengthened to dissolute the preponderance of road transportation. Second, a new large port must be developed at Gadeok island to handle the increasing container traffic in the years of 2000. Third, the port authority must be established under the cooperation of the central government and local government to comply with the necessity of the synthetic control for city and port. Fourth, the Inland Clearance Depot in going must be promptly completed to establish the efficient and synthetic container logistics system.

  • In this paper, we implement an m-LIS(Mobile-Logistics Information System) for an effective logistics management in consideration of logistics process and work environment. The m-LIS could perform the entire business process every minute and promote the work efficiency by tying up with ERP and POS system. Moreover, this system could enhance the management level of service and supply chain. Due to the reason that the existing logistics business was not computerized and automated, most of operation was accomplished by means of workers experience and convention. This problem brought about both the ineffective management and logistics quality deterioration by weakening the control power of the logistics site. In order to solve this problem, we put focus on providing the real-time operation monitoring environment on the spot, the satisfaction of the efficiency on the spot, and the optimized system by building up the logistics information system. Furthermore, we attest that the new logistics system could properly cope with the increase of the quantity of goods transported owing to stable logistics information support and the market expansion and growth caused by the firm interface between the new ERP and its related system.

  • Recently, International commerce has continuously expanded with the development of logistics technology. However, the cost of international logistics is rising rapidly. The Korea International Trade Association (2021) proposes that the use of international commercial terms in Incoterms® could be an effective way against logistics costs. The purpose of this study is to verify the effect on the flexible operation of international commercial terms. For the detection of variables and data collection for empirical analysis based on previous studies and in-depth interviews. The questionnaires were distributed after pilot-study to a random sample of companies based on the list of members such as the Korea International Trade Association, the Korea Trade-Investment Promotion Agency, and the Global Small and Medium Business Association. A total of 800 questionnaires were distributed, and 166 were used for empirical analysis. The results of this study are as follows. First, mutual cooperation and Flexibly using of international commercial terms has a positive (+) effect on logistics efficiency. This is in line with the study of Yang (2021) and Stojanović et al. (2021) that logistics by using international commercial terms will increase the efficiency of logistics. Second, use of international commercial terms based on mutual understanding mediates the relationship between the logistics environment of the other country and the logistics efficiency. As in the study of Vidrova (2020), it is important to operate on international commercial terms mutually.

  • In this paper, we suggest the system analysis method that links IDEF0 and conceptual analysis. Based on the method, we propose the implementation methodology that can be used to build CALS/EC systems in logistics industry. This paper presents data characteristic derived using ICAM DEFinition(IDEF0) and conceptual data modeling. Modeling methodology has been widely used for analysis and design of an enterprise information system. Further IDEF has been considered appropriate for developing functional and database models for the logistics environment.

  • The article focuses on the need to deepen the issue of human resource management in logistics processes. It is noted that changes in market conditions and turbulence in the institutional environment require managers to form a highly effective human resources policy capable to ensure the innovative development of the enterprise. Functional strategies for human resource management in logistical processes are proposed, namely: adaptive, innovative, selective and exclusive. Innovative technologies that should be used in the adaptive human resources policy process are identified.

  • This study sought efficiency of collaboration between manufacturers and distributors by finding a way to improve logistics efficiency in order to save distribution cost and standardize packaging together with profit generation by way of simple-display packaging in discount stores. For the study purpose, the impact of products with RRP (Retail Ready Packaging) by each discount store on the collaboration achievement such as loading efficiency was observed. From this observation, an alternative packaging system that can improve logistics efficiency between manufacturers and distributors was sought and the role of distributors in distribution standardization was explored. The purpose of this study also includes suggesting some implications on future basic direction of environment-friendly management. If this study would induce distributors to have more interest in distribution standardization and if logistics efficiency would be enhanced by the operation of packaging system considered of compatibility with pallets, this study would have academic significance and create practical values.
