This study established a truck dispatching model adopting 01 decision variables to rationally allocate truck transportation in openpit mines, maximize the total loading and unloading volume of trucks, and solve the problem of the inability of the truck dispatching model to guide production in openpit mines because of nonspecific results. The model considers loading and unloading logical ...
