Abstract: To solve the conflicts resulted from the inconsistent targets of production and distribution,production system and distribution system should be integrated.In this paper,an integrated system is proposed which covers the distribution nodes,the final product inventories,the producing center and the material inventories in a demand-pulled supply chain.Furthermore,the optimal parameters of each subsystem,which make the system total cost be minimum while a given service level of markets demands is met,are determined by a genetic algorithm together with a generation algorithm of valid chromosomes.Analysis of an example concludes that the improvement of service level needs no increase of the total cost,in other words,the service level could be improved while the total cost could be reduced if the production system and the distribution system are integrated.

Key words: supply chain, production-distribution integrated system, recursive equation, genetic algorithm, parameter optimization
