The purpose of this paper is as follow. The first is to investigate ship instrument supplier's and consumer's needs. The second is to study a feasibility of international ship instrument distribution center at Busan port. Therefore, the research scheme was experimented through a questionnaire survey answered by 878 companies. The results of this research indicate the necessity of ship instrument distribution center. The results of this study will be helpful for the success management of ship instrument distribution center.

Nowadays, a logistics and distribution center plays an important role in all industries. In addition to its traditional functions as a storage and unloading facility the distribution center serves as an assembly place for information, a source of information, and a turning point for the flow of information. On account of the above-mentioned reasons, each and every industry has increasing need of logistics distribution center. At this juncture, the present author thinks that it is necessary to make a study of the establishment and maximization of a ceramics logistics distribution center as a way for activating the ceramics industry.

In this paper, we suggest a strategy to implement RFID in the Marine Equipment Distribution Center. Although RFID technology has be applied to the various business areas, due to the immature technological market and other reasons, for the successful RFID implementations, it is necessary for the company to review RFID implementations methodology. The aims of the Marine Equipment Distribution Center is to share storages for the marine equipment enterprises and to gain the max efficiency in the logistics flow. To achieve this goal RFID can be one of the alternatives. This paper suggests major issues that can help to reach the successful implementation of RFID in the distribution center.

This paper considers a problem of locating both distribution centers and retailers in a zone-dependent two-level distribution network where either a distribution center or a retailer should be located in each zone. Customer demands of each zone should be satisfied directly from either its own distribution center or its own retailer being supplied from a distribution center of another zone. The objective of the proposed problem is to minimize total cost being composed of distribution center/retailer setup costs and transportation costs. In the analysis, the problem is proved to be NP-hard, so that a branch-and-bound algorithm is derived for the problem. Numerical experiments show that the proposed branch-and-bound algorithm provides the optimal solution efficiently for some small problems.

In spite of recent stagnation, the rate of electric consumption has highly grown in accordance with a high cultural livings, Also, a usage of electric energy is growing with development of multi-information society. To make the matter worse, hard work of highest order is required because distribution system are widely spread and complex. And consummers demand for the electricity of good quality and it is obstracle to be not able to train related technitian for maintenance without an interruption of electric power. It is sure the counterplan of uninterruption of electric power is very necessary. In this paper, considering the working circumstances, we presented the necessity of work method, the effects and the future prospect for uninterruption power supply.

The energy distribution was calculated for an electron beam from an electron linear accelerator developed for medical applications using computational methods. The depth dose data for monoenergetic electrons from 0.1 MeV to 8.0 MeV were calculated by the DOSXYZ/nrc code. The calculated data were used to generate the energy distribution from the measured depth dose data by numerical iterations. The measured data in a previous work and an in-house computer program were used for the generation of energy distribution. As results, the mean energy and most probable energy of the energy distribution were 5.7 MeV and 6.2 MeV, respectively. These two values agreed with those determined by the IAEA dosimetry protocol using the measured depth dose.

The influence of current distribution on the transport current loss in vertically stacked high-$T_c$ superconductor (HTS) tapes was evaluated. AC loss was analyzed as a function of current distribution by introducing a current distribution parameter through a numerical method (finite element analysis). AC loss under non-uniform current distribution is always higher than that for a uniformly distributed transport current in a conductor. Although the effect of non-uniformity is relatively insignificant in low transport current, AC loss increases substantially in high transport current regions as non-uniformity is enlarged. The results verify that non-uniform current distribution causes extra loss by examining the cross-sectional view of current densities in stacked conductor.

Recently, online grocery shopping has been increasing with the development of internet, mobile, and IT technology due to the proportion of consumers changes like increasing single households and double-income couples. Therefore, online sales from distributors with offline stores have also increased, and the offline retailers are facing their limits in dealing with store-based online channel they have carried out. Domestic offline retailers benchmarked overseas advanced retailers to solve this problem by reviewing about developing the online-only distribution center. However, much investment is needed in order to operate the distribution center with the new concept from abroad. In this study, we have reviewed the current online grocery market trend and the theory related to developing distribution system of the online mall. For offline retailers, we have reviewed the case which developed the distribution center applied to the nation's first online-only distribution center. The purpose of this study is reducing trial and error for local retailers in developing online-only distribution centers and suggesting ways to improve investment effect.

Many of these studies represent a large scale distribution network with a unified formulation by using defined symbols. This can be evaluated as a valuable progress toward accomplishing of a systematic approach the area of distribution network. Unfortunately. transportation problem and inventory policy applied in these studies have an assumption of using an unique supplier for calculating the transportation cost among each distribution echelon. This assumption can cause many problems such that transportation problem is assumed as linear problem, too many number of distribution center are allowed to operate and many more. In order to overcome above unrealistic problems, we developed an algorithm of responding to customers' demand under the refill allowance of same level supply as anew constructional method of inventory distribution network. When backorders are happened in regional distribution center, this algorithm allows transferring finished goods to customer directly from vicinal Regional distribution center instead of existing central distribution center for quick response.

The distribution facilities fault has been anually shown about 13% all of the total distribution faults. Therefore, to prevent, the distribution facilities we have to manage them properly during their life time and enhance their quality and advance preventible maintenance, that is predictive maintenance or condition based maintenance. This paper presents the aging characteristics and the degenerating factors. Accordingly, improving the enhanced quality of distribution facilites is expected to contribute the electric power operation constantly.
