Abstract: Analysed the truck dispatching theories at home and abroad, directed against the mine production objective requirements and limitations of existing theories, the computer-based multi-objictive comprehensive truck dispatching optimal models are buit up. This paper presents a comprehensive dispatchingoptimal algorithm concerning objective requirements, model building, selection of criteria, and objective realization; using objective programming algorithm to replace linear one to optimize the trnck flow inmines. Arming the practical problems of a living mine as example the research is made. The results from theresearch show that the built models and algorithm are correct.
