The farm planning problem which is related to the whole farm management, in a fact-finding investigation of farm management→data arrangement→making plan→practice and evaluation, plays an improtant role in improving the management. The acientific and/or mathematical method at present however, can not deal with fuzzy logic subjectivity of the decision maker. Therefore, the present method obviously need a logical correction, sure there are many cases of unfitness and unsuitability. In present paper, we asumed that there were many fuzzy logic applications in the natural environment that affected the decision of farm manager. We studied the upland and beef mixed farming to determine if the fuzzy thory could be effectively applied in farm design. Also, we discussed the modeling of the fuzzy possibility problem, one application of fuzzy theory, as a method for the farm planning problem. First, we attempted to estimate the upland and beef mixed farming with a fuzzy problem which was considered in two directions : one is the fuzziness of the desired level for the goal and constraint of the decision maker and the other is the fuzziness of the coefficient of objective function and constraint conditin. Secondly, we discuss the positive analysis of upland beef mixed farming in Ketaka-cho, Tottori, as a concrete example that the fuzzy theory could be applied effectively with the various fuzzy logic applications in the decision making process of farm planning.
