In this study, traditional treatment scenario of food wastes that collected and transported food waste is recycled in large treatment facilities and suggested treatment scenario of onsite zero discharge system that food waste is treated in housing complex were supposed. The scenarios were compared and analyzed by capital expenditure, oil consumption, $CO_2$ emission quantity, operating expenditure and management expenses. The capital expenditure, oil consumption and $CO_2$ emission quantity of small scale dispersion dealing method is the lowest compared to traditional treatment method. As a results, it is possible to obtain the effect that operating expenditure was reduced by 91% and management expenses was reduced by 40% with suggested treatment method. The treatment method that have low capital expenditure is tend to lower oil consumption and $CO_2$ emission quantity. The small scale dispersion dealing method have the lowest capital expenditure, oil consumption and $CO_2$ emission quantity and the linked method with sewage treatment have the highest expenditure and $CO_2$ emission quantity. Eventually, the optimal model of onsite zero discharge system in housing complex is small scale dispersion dealing method.

This study set out to develop a logistics rationalization model to reduce logistics costs including return route costs by using open information systems that overcame the limitations of the old closed logistics systems by the corporations and applying the principle of freight car sharing among them. In recent years, information infrastructure that can be easily shared by many such as information networks, however, One of the causes of rising logistics costs is high empty transfer rates on return routes after goods are transported from the distribution center of each company to consumption sites, It is propose to promote logistic efficiency and innovation. The study especially identified a logistics rationalization plan by examining and analyzing the stages of transportation on the circulation route of a distribution system from the distribution center of a corporation to consumption sites and the empty transfer rates and their current state.

The scale and operating conditions of logistical systems very sensitively varies according to the variation of traffic intensity that is affected by the arrival characteristics of trucks and the attributes of loading/unloading services in logistics facilities. More exactly, logistics costs are incurred according to variations of traffic intensity. which are intimately linked with in a given time period. Also. although traffic intensity changes minutely, the range of cost variation is wide. Nevertheless, with regard to operating logistics systems, the existing studies make no attempt to analyze these factors. Therefore, it was the purpose of this study to determine the optimal traffic intensity to minimize excessive logistics costs resulting from the generation of unnecessary costs such as waiting costs and overcosts in operating a facility. For the purposes of this analysis. a determination model of optimal traffic intensity was constructed according to queuing theory. The inflow/outflow conditions of trucks and the terminal operational conditions were collected from an off-dock container terminal in Busan. On the basis of this data. the optimal traffic intensity that could off-set excessive waiting and operating costs was determined quantitatively. Also. using the optimal traffic intensity to be determined. we consider the improvements of operating system in the logistics facilities.

Companies must strengthen core competencies by concentrating resources to secure a competitive edge and operate efficient processes from a company-wide perspective. To this end, it is seeking to concentrate its capabilities and reduce costs by pooling non-essential tasks or facilities that require a lot of time and capital at a strategic level. Therefore, logistics companies should actively utilize logistics coorperate system in order to maximize the use of logistics resources according to the limitations of human resources, physical resources, and time. This study is an empirical analysis of the strategy of logistics companies and the impact of logistics coorperate on corporate performance, and a survey and analysis was conducted on domestic logistics companies. The results of the empirical analysis showed that the cost·relationship·information-oriented strategy of logistics has a positive(+) effect on the financial·operation·strategic performance indicators of companies through logistics coorperate. The results derived from this paper will be used as an important determining factor in establishing a logistics strategy and logistics coorperate to improve the performance of logistics companies and logistics service companies.

상품을 만들어 소비자가 있는 곳에 보내기 위해서는 기차나 비행기, 배, 화물 자동차 등을 이용해 수송해야 한다. 또 적당히 안전하게 포장해야되고, 때에 따라서는 일정기간 보관해야 하며, 이런 일들을 위하여 하역해야 한다. 이러한 일련의 이들을 물류(물적유통의 줄임말)라고 하는데 우리나라의 경우 이 물류에 드는 비용-물류비가 외국에 비하여 더 많이 들고 있다.

현대 산업에 있어 그 비중이 급속히 증가하고 있는 물류산업의 효율적인 업무 처리와 국제 경쟁력 확보를 위하여 물류정보시스템 구축이 활발히 진행되고 있다. 이는 컴퓨터 기술의 발달과 함께 시간, 인력 및 비용이 많이 소요되던 종래의 거래서류 처리업무를 EDI 로 처리함으로써 가능해졌다고 볼 수 있다. 거의 30 여년간 기업간 온라인 상거래의 기본 수단으로 이용되어 온 EDI 의 동적인 변화 대응부족이나 고가의 네트워크 유지비용 등의 문제점을 극복하기 위해 유연한 변화수용 능력과 뛰어난 확장성을 가진 차세대 웹 문서인 XML을 이용한 XML/EDI가 등장하였다. XML/EDI는 XML, EDI, Agent, Template, Repository 의 5 가지 요소로 구성되어 있으며, 다른 요소들의 기본이 되는 Repository 는 거래에 필요한XML/EDI 태그들의 정의 및 의미를 저장하고 있으며 거래 당사자들이 검색하여 볼 수 있는 인터넷상의 공유 디렉토리를 말한다. 본 연구는 XML/EDI 물류정보시스템 구축을 위한 전 단계로서 현재 개념 적으로만 정립되어 있는 Global XML Repository 의 구성에 관한 연구이다. 특히 KEDIFACT 표준을 따르는 물류 EDI 를 바탕으로 Global XML Repository 내의 구성요소들을 정의하고 체계적으로 분류하는 것을 중점적으로 연구하였다.

The purpose of this study is to evaluate the social costs of inland trucking and maritime transport between Kwangyang Port in Korea and the Great Lakes in US. Also, this study compares these social costs each other, and finds the way how to internalize them for the efficiencies of national logistics policies. This study uses the Contingent Valuation Method to evaluate the social costs for the two transport modes in each country. The final result is that the social cost difference between inland trucking and maritime transport around US Great Lakes area is not so significant that there are not many chances to enhance the maritime transport in the region. However, in case of Korea, there is significant difference in social costs between the two transport modes, so that Korea government may have a lot of chances to improve the seaborne trade by way of various internalization policies.

The improvement in logistics competitiveness is the key element of corporate competitiveness in the era of severe competition among companies and high oil prices due to globalization. For this reason, this study analyzed the effect of transportation mode selection factors of Indonesian export companies on the logistic performance in accordance with the logistics environment. The results of the analysis show that only the cargo characteristics, which are the transportation mode selection factor of export companies, had a significant effect on logistics; the services, time, and expenses, on the other hand, had no effect on logistics performances. This result reflects the poor logistic infrastructure of Indonesia. While the export company considers service, time, and expenses when choosing transportation mode, it had no effect on logistic performances due to poor logistic infrastructure. The poor logistic infrastructure of Indonesia has caused a rise in the overall logistic expenses of companies due to excessive transportation time over the transportation distance, unavailability of on-time acceptance and delivery, and increase in the transportation expenses and subsidiary expenses. These are also the factors that decrease the competitiveness of export companies and affect the promotion of the manufacturing industry and foreign investment for the purpose of job creation and industrialization by the Indonesian government. Therefore, the logistics infrastructure must be improved initially. This study determines various points in terms of the logistics infrastructure environment of Indonesia, a developing country, using previous studies and provides their implications.
