According to the fast-paced environment of information technology and improving customer services, the design activities of logistics systems improve customer centric services and delivery performance implementing e-logistics system. The fundamental design issues that arise in the delivery system planning are optimizing the system with minimum cost and maximum throughput and service level. This study is concerned with the integrated model development of delivery system with customer responsive service level for DCM, Demand Chain Management. We used a two-step approach for this study. First, we formulated the supply, center facility planning using stochastic set-covering problem and assigned the customers to the supply center using clustering algorithm. Second, we developed vehicle delivery planning for a supply center based on GIS, GIS-VRP. Also we developed a GUI-type computer program for proposed method for supply center problem using GIS and Geo-DataBase of Busan area. The computational results showed that the proposed method was very effective on a set of test problems.

The objective of this study is to analyze the present status of futures contract in Korea. Korea are taking part in 3 types of futures market: foreign futures market, KOSPI 200 stock index futures market of the Korea Stock Exchange(KSE), and the futures market of the Korea Futures Exchange (KOFEX). The futures contract trading volume in all the markets shows continuously increasing trend. Trading volume in foreign futures market realized 124 billions dollars in 1998, which were 7 times more than trading volume in 1993. The amount of KSE's KOSPI 200 stock index futures increased 9 times form 1996 to 1998. The KSE have moved into the top 10 exchanges in the world. The futures volumes in KOFEX amounted to 7,508 contracts a day on the average September 1999. The size of futures market, however, is still small relatively to spot market and there are many problems in Korea futures markets such as small scale of futures commission merchants, unfair trading in spot market, regulations, irrelevant acts, and low level of understanding about futures contract. To activate futures markets, it is necessary to exploit various new futures contracts which everyone can recognize easily, to improve futures trading system that is able to derive speculative investment, to strengthen public relations and education, and to establish competitive market system through relaxing regulations and restrictions, consolidation all kinds of law relevant to the futures market.

To analyze the mechanism and structure of agricultural products marketing in Australia. the institutional, historical and commodity approaches were conducted. The most important features of Australian agriculture relevant to agricultural marketing are the price fluctuations stemming primarily from a inelastic supply of agricultural products, a heavy dependence of foreign markets and high levels of production risk due to the influence of weather. To stabilize the price, the complex pattern of regulations and institutional involvement have been introduced in major agricultural products marketing process especially by the Australian political parties which has an agrarian-based constituency. The most prominent characteristics of Australian agricultural marketing have been the presence of Statutory Marketing Authorities(SMA) in the form of marketing boards or corporations since the early 1920s. The federal SMAs are oriented toward export marketing such as licensing of exports and overseas product promotion while state SMAs arc oriented toward regulating marketing such as price setting including powers of compulsory acquisition of a commodity within their boundaries. The functions SMAs undertake are determined in large part by the constitution. In recent years governments at the State and Federal levels have sought to provide SMAs with more commercial flexibility and have taken steps to deregulate agricultural marketing arrangements for some major commodities such as wool, wheat, meat and dairy products. There is, however, still relatively strong regulatory controls and institutional involvement in Australian agricultural products marketing.

The objective of this study is to analyze marketing activities of greenhouse horticulture farms in the eastern region of Kyungnam province. To achieve this objective, 204 greenhouse horticulture farms at 10 villages of the region were surveyed by prepared questionnaires during March-April 1995. The major findings of the analysis are as follows: 1) Greenhouse horticulture farms seemed to have troubles in finding sales outlets. A big portion of the greenhouse production was still being sold to private wholesale markets outside the legal marketing system, whereas most of the standardized products were being sold to legal public wholesale markets. The role of agricultural cooperatives was very weak in the marketing of greenhouse horticultural products. To solve the problems, market outlets such as export and direct sales should be developed jointly by producers, cooperatives, and local and central governments, and agricultural cooperatives should actively and practically participate in the marketing of greenhouse horticultural products. 2) Selling products before harvesting was popular in some horticultural products such as water mellon and spring cabbage, Many farms were dissatisfied with low contract prices, but they were usually doing it mainly because of labor shortage. Old greenhouse facilities should be mechanized and automated as soon as possible to overcome the labor shortage problem of the farms. 3) Standardization of greenhouse horticultural products at the farm level was principally based on eye-measuring by size, appearance and color. Constructing facilities for joint standardization would help lessen the labour burden of the farms and enhance the degree of commodity value of greenhouse horticultural products.

The objective of the study is to conduct an empirical study on consumers' rice consumption behaviors and purchase activities. To achieve this objective, a case study on consumer households was conducted in Pusan during March 1992. 310 questionnaires collected were analyzed by tables and discrete regression models. The major findings of the research are as follows. 1. More than half of the consumers purchased the rice at least once a month from the traditional rice retailer. The quantity each purchase usually did not exceed 24㎏. It was found that a household owning a car or having more members directly purchased from the rural markets, farmers or the reliable relatives. Rice consumption was positively related with the size and the proportion of teenagers of a household, but negatively related with the education level and work status of the housewife. Without any standard or regular buying date, many consumers purchased the rice when they ran out of rice. Though 80% of the consumers surveyed wanted a small package of rice, only 10% of the consumers actually used to purchase in a small package. 2. Consumers had a strong preference to high-quality rice. A household with a highly-educated or aged housewife seemed to prefer to it than others. It was found that consumers were willing to pay more price to the clean or pollution-free rice. The price premium for the clean or pollution-free rice was positively related with the education level and the age of the housewife, and the income of the households. But the available information on the quality of the rice was quite limited to consumers. The only source of the information on the quality of rice for most consumers was the rice retailer, though it was widely believed that an illegal and unfair rice marketing was prevalent in the retail market. 3. Only 3.5% of the consumers surveyed had the experience of buying the government rice recently and 60% of consumers answered that the government rice was lower in quality than other rices. 11% of consumers surveyed recently bought the agricultural cooperative rice and most of them believed in the quality and the weight of the rice. The main reason that many consumers did not consume the agricultural cooperative rice seemed to be the less availability of the shops selling the rice around the household. Since 41.6% of the consumers surveyed would purchase the rice imported if it were cheaper and better in quality and they were especially interested in the quality of the rice, it seems to be very important to enhance the quality of the domestic rice varieties in order to compete with the imported rice. 4. Therefore, a rice marketing system for the distribution of high-quality rice should be developed to meet the changing rice consumption behavior. First, the government should reform the current purchase and release policy in order to establish the distribution system of high-quality rice. Second, agricultural cooperatives should play an active role in the establishment of grading and standardization of rice to prevent the illegal and unfair rice marketing. Third, rice retailing should be liberalized so that consumers easily purchase rice in a small package at the near-by shop. Fourth, the production of low-polluted rice should be encouraged and the quality certification system to guarantee the low pollution of rice needs to be devised.

In order to research the water quality of artifical BOSUNG KANG which is now constructing for multi-purpose dam and water source of JOO AM DAM and DONG BOK CHUN and its branch we did twice in april 1988, September 1989 and the result is below. 1. In everywhere pH was 6.8∼7.6 and very similar to our general rivers and there is no evidence to change the pH 2. In the first investigation DO was 7.2∼8.4 ppm and it was lower than another river but in the second investigation we knew that our research river is a cleaning water area relatively, because DO was 8.2∼9.2 ppm and it is higher than 7.6 ppm of KA PYUNG CHUN whic is estimated low pollution relatively. 3. Except site 9 and site 13, BOD was below 4 ppm so it was estimated good quality 4.4 ppm of site 9 and 4.6 ppm of site 13 was resulted from special condition of this constructing river. 4 NH₃-N which is a criteria of river pollution was 0.02∼0.06 ppm of the second investigation and it was proved that second investigation was increased than 0.01∼0.05 ppm of the first investigation. This was influenced of inflowed material from near the hill because of heavy rain. 5. In the second investigation the NO₃-N was higer than that of the first investigation. The reason was that in the first investigation because of a rainy season direct irradiation of sunlight was short. 6. In everywhere chlorine ion and total hardness was defected homogenously compared with another river. It was not because of point source contamination but because of the nature of the soil. 7. It is very often that PO₄-P is shown because of decomposition of stool and urine and chemical fertilizer and pesticides but in this research area the quantity of 0.021∼0.040 ppm is resulted from geographical feature rather than outside factor compared with 0.024∼0.030 ppm of JONG CHUN which is estimated as a low pollution level relatively. 8. Normal bacteria and E. colis is lower than another river but in site 4 E. coli was shown 4.9×10 and when we enlarge a amusemene park of BOK LAE CHUN. We must consider the water quality management.

The objective of this study is to present the method of improving the efficiency of the rural rice market by investigating rice variety chosen. post-harvest rice handling and sales activities of farmers. To achieve this research objective, a case study was conducted on the sample of 193 farms and 4 agricultural cooperatives located in 4 districts(myuns) of Kyungmnam area. The major findings of the study are as follows. 1. The willingness of farmers to produce a high-quality rice in terms of variety choice and post-harvest technology was not strong mainly because the government policy had not reflected quality in the purchase of rice. Labor shortage problem also made it difficult to produce a high-quality rice at the farm level. 2. Farmers were selling rice mostly during the harvest period due to the cash demand and commercial rice marketing activities were weak due to the large volume of the government's rice purchase. Therefore, farmers seemed to have trouble in finding an outlet to sell the rice. 3. The possibility of illegal rice marketing was very high due to the lack of standardization and grading of rice in rural areas. In spite of their crucial role in rice marketing. small-scale rice mills were engaged in excessive competition only to cause many problems. Rice marketing connection production area and consumption area directly without any involvement of wholeasler is very popular now, but it did not seem to contribute to the improvement of the rice marketing efficiency in terms of marketing cost. The reason is that the transactions are mostly dealt in a closed small-scale form. 4. Therefore, following measures are recommended to supply the high-quality rice, to prevent the illegal rice marketing, and thus to achieve the efficient rice marketing : First, integrated rice handling facilities should be constructed in rural areas; Second, a modernized rice mill with an economy of sacle should be formed by combing small-scale mills to guarantee the supply of high-quality rice. Also measures to force the quality control of rice in the mills are necessary. Third, packing and grading should be standardized. Fourth, the rice wholeasle market and the involvement of agricultural cooperatives in the rice marketing should be activated. Fifth, rice production system should incorporate the use of rice.

This study develops an integrated logistics planning model for determining optimal patterns of supply centers and inventory allocation. This research addresses the formulation of those complex two-echelon logistic system planning problems incorporating location, resource allocation and optimal delivery based on minimizing the amount of shortage and damage from shortage of supplies and travel distance or time. The solution method developed to solve the problem applies a three step sequential approach, those are : - first step, supply center location and inventory allocation using stochastic set-covering problem, - second step, optimal sector-clustering to support the unit forces, - third step, optimal vehicle route scheduling based on genetic algorithm. Also, we have developed computer programs for each steps and have shown the results of sample non for supply delivery problems in a hypothetical battle area. It was known that the proposed model was a very acceptable for the optimal supply delivery considering inventory allocation and vehicle routing problems.
