Abstract: Aiming at the present situation of lacking of scientific and reasonable scheme in farm machinery scheduling and allocating, farm machinery scheduling and allocating was proposed based on owners’ choices and the optimization models with the goal of high-income and low-cost in this paper. According to the characteristics of farm machinery scheduling and allocating, the integrated priority rules were analyzed and the scheduling and allocating algorithms with heuristic priority rules were designed. Different scheduling and allocating schemes were obtained by calculating farmland instances with the general algorithm and the proposed algorithm in the paper. Compared with the aspects of service income，scheduling distances and waiting time, scheduling and allocating scheme acquired by the proposed algorithm was superior to that by the general algorithm. The effects of farmland amount and parallel degree on the algorithm performances were analyzed. It was concluded that the algorithm proposed in the paper is more effective and reasonable.
