Abstract: Production scheduling is an important issue in management of mining industry.The previous production scheduling does not consider the randomness and dynamics of the tasks，but there are many random service sections in production.In view of the matching of production tacks and service nodes，a production scheduling based on queuing models is proposed.This proposal satisfies the cost saving，and can assign tasks to different service nodes according to their characteristics so as to lower the production costs.The Matlab experiment shows that this proposal is effective.

Key words: Queuing model, Production scheduling, Cost optimization, Mining industry
