Abstract
There is a lot of previous research on profit maximization in agriculture. In a previous research, crop
rotation problem and cultivation management problem are solved as one integrated management problem in
order to maximize the profit in agriculture under cost constraints. But in the previous research, the integrated
management problem for only one farm field has been studied. In this research, the cost constrained integrated
management problem for multiple farm fields is studied. A new integrated management method for multiple farm
fields considering cost constraints is proposed. The cost constrained integrated management problem is odeled
by Markov decision processes. The proposed method maximizes the expected profit of multiple farm fields under
cost constraints by dynamic programming. In the numerical calculation results, adaptive crop selection examples
and cultivation action selection examples of multiple farm fields under cost constraints are confirmed. This
research is basic research, and future extended research is required. For example, as a more realistic problem
setting, the cost constrained integrated management problem for multiple farm fields considering crop price
fluctuations is interesting.
