In order to provide a basic information for optimum dairy feeding system in Korea, mathematical models for estimating the production cost of grass, wild grass, dried hay and silage were developed by analyzing the dairy feeding system. Also, a computer program for calculating these models was developed and tested by using various practical data. Results of these tests were analyzed each other and it was found that many factors affected roughage production cost. However, land price for paddock was the most significant factor of them.

In order to determine the optimum dairy feeding system, a L.P. model was developed. The program consisted of 8 variables; the daily feeding quantities of formula feed, green grass, forage, wild grass, hay silage, rice straw and substitutive feed. Also, it was formulated with 25 constraint functions. The major input data of L.P. are listed as follows. 1. Weight of dairy cow. 2. Amount of average milk production per day. 3. Daily maximum feeding quantity of each feed. 4. Production and purchasing cost of each feed. 5. Nutrient content of each feed.

The main objectives of this studies are to present the most desirable rice processing complex model system in a given our situations by comparision and analyzing the major factors and, also recommend the future prospect of the rice processing complex in Korea. There are 3 different rice processing complex models in Korea. Those are concrete bin, flat type steel bin and square bin. These systems have a lot of differences and have their own characteristics such as capital requirement, efficiency, storage capacity and quality controls. The major problems of the existing rice processing centers in Korea are high fixed cost and the unbalnced systems. Following is summary to solve this problems: 1. Development of the large scale harvester and high speed continuous dryer. 2. Quality inspective system of bulk grain and large scale temporary storage facilities. 3. Large size readjustment of arable land. 4. Select the convenient location of rice processing center and formulation of well equipment facilities.
