Outline of Final Research Achievements

In general, when formulating real-world agricultural problems as multiobjective programming problems, we are often faced with the difficulty of handling uncertainty such as profit coefficients for the crops and/or water supply possible amount. To deal with such a difficulty, we consider several kinds of agricultural programming problems under uncertainty. Based on the chance constraint methods, we formulate multiobjective programming problems involving random variables, fuzzy numbers, and fuzzy random variables, and develop interactive algorithms to obtain a satisfactory solution of the decision maker. The proposed algorithms are applied to crop planning problems. On the other hand, to deal with water resource programming problems, we formulate multiobjective fuzzy random simple recourse programming problems, and develop an interactive algorithm to obtain a satisfactory solution of the decision maker. The proposed algorithms are applied to a rainfed agriculture planning problem.
