Abstract:The optimization of the yard is an important issue of the coal terminal. The paper presents two new stockpiling strategies which can improve the stockpiling efficiency for the yard optimization, with the formal description of the system and gridding the continuous space of the yard, then establishes a mathematical model for the coal terminal of gridded yard. According to the modeling and simulation of discrete event systems, we establish the gridded simulation model of the logistics system of coal terminal. Combining with the emulation test of practical professional coal terminal, we study how the new optimized stockpiling strategy affect the terminal’s operation. Meanwhile, we validate the novel optimized stockpiling strategy of engineering applicability.
