After the Uruguay Round, Korean agriculture industry has been protected and reared with government grants. However, until now there has been very minimal development to establish a solid export industry which can make the most of the trade agreements in place. There has been much research on ways to expand agricultural exports in order to respond properly to this ever changing environment and sustainable agricultural industry. As all other export industries, an efficient logistics network is paramount in order to allow the agricultural industry to respond to changes in demand and penetrate global markets. The lack of systematic logistics activities such as packaging, transportation, unloading, storage, and information transfer in farms has been a major factor in the inefficiency of the agricultural industry resulting in minimal development. From this perspective, 3PL was proposed and applied as a way to build on the streamlining of export of agricultural logistics system. The Agri 3PL is considered as an efficient agricultural exports method as a new concept connecting producers with exporters.

In order to determine home delivery service routes, conditions specified for each parcel such as customer-assigned delivery times and parcel contents should be considered, so the conventional route search algorithms have some limits to be applied for home delivery services. In this study, a multi-purpose route searching algorithm is suggested in order to deal with every requirement of deliveries that vary in delivery distances, contents and appointed times. A simulation study to verify the performances of the system with example data of Seoul and Kyungki provinces shows that it significantly improves the customer satisfaction and the productivity of delivery businesses.

Door to door service is a typical method for individual parcel deliveries. In the current delivery information system, a delivery person manually inputs the information of many delivery results, which causes inefficiency and difficulties of tracking deliveries. This study suggests an enhanced delivery information system which has the following two characteristics. Firstly, a tagged RFID(Radio Frequency Identification) transmits the delivery result information to the main server by just collecting RFID at a place of destination. Secondly, with the characteristics of rewritable method, the collected RFID is to be input new information and tagged to other parcels.

"Domestic delivery service" is defined the service to deliver goods or packages from point of senders to point of receiver. With the characteristics of door to door, it is must a service provider should know the exact location of destination assuring best utilization of moving path. Generally, location information consist of postal code and address only, which result in difficulties to identify the precise location of destination. It is relatively less correlated between the information that address refers and practical location in Korea address system. For example, the next door to house number 100 is not always house number 101. Therefore, a delivery man additionally uses a paper map or a GPS navigation which carry extra job to input every code of location to the device in order to know precise location. It is also very inconvenient that every delivery man identify the location that address information refers and make a personal decision of the optimum moving path dropping each destination without calculating provisioning process of whole delivery path. As explained above, it is inefficient to find information delivery service required and to generate the optimum path. In results, these difficulties bring in delay of service and increase of cost. In this point, the contents of the thesis suggest a GPS navigation system easy to obtain accuracy of delivery information which enables to automate optimum moving path based on RFID which contains location information.

In this era of knowledge and information of the 21st century, the source of a nation's competitive power consists of human resources and material resources and the importance of human resources appreciates highly. The number of small and medium enterprises which are the core of national economy covers over 98% among whole domestic enterprises of Korea. Competitive power of small and medium enterprises comes from human resources development. For the development of human resources, small and medium enterprises are trying to expand their learning organizations in the company. The analysis of outcomes of administering the existing learning organizations shows that learning organizations contribute highly to the improvement of the productivity of small and medium enterprises. And the analysis also shows that the participants of learning organizations and middle management and executives who support and encourage them recognize the necessity of learning organizations and that it should be disseminated throughout other enterprises. Therefore government's supports to establish learning organizations in a company are required to expand.

Recently, many companies want to accept and operate ERP (Enterprise Resource Planning) system in their fields ERP does not only include business, but also include finance, account, trade, personnel and BPR(Business Process Reengineering). Especially, it is necessary to have ERP system for companies which have lots of external business such as trade and communication sector. And then, in this paper, I will think about OLTP (On-Line Transaction Processing) system for operating ERP system and improve its defects that can operate more effective sales, circulation, demand plan. But it is regrettable that I can not make a comparative analysis with other systems because the ERP system is still on the introductory stage for the company studies and the benefits have not been realized yet. Another limitation of this research is its narrow scope of study in which only the raw material inventory system for a single company is covered. In the future, however, ERP system would be adopted by many corporations, which would help us to launch a comparative study on the results of ERP system implementation as a future direction of research.
