Abstract

Abstract: To address the uneven task distribution among multiple agricultural machines (referred to as farm machinery) and the high time cost due to numerous turning points at intersections, this paper proposes a task planning method that combines a pre-heat multi grouped genetic algorithm (PHMGA) with the turn A* algorithm (tA*). PHMGA allocates tasks to each piece of farm machinery based on the known environment, ensuring balanced workload through a cost objective function that considers travel, operation, and turning distances. It also designs various operators and strategies to search for nearoptimal solutions. The tA* algorithm is used to select paths in the fields, avoiding complex areas with many turning points through turning penalties, thereby further reducing operation time. Simulation results show that our proposed method effectively balances the workload among the farm machinery and significantly reduces operation and waiting times, achieving a reduction of 5% and 56%~67% respectively compared to traditional methods.
