Abstract: In order to meet the requirement for aided decision-making, combined with the characteristics, guided by the overall technical scheme, Railway Passenger Transport Marketing Aided Decision System(PMDS) was designed and implemented based on Railway Ticketing and Reservation System(TRS). Many new methods and technologies were applied in this System. The technologies, such as data source integration, statistical algorithm optimization, application load balancing, function expansion, were studied in this paper. The methods and technologies were helpful to implement automation and intelligence of decision-making, effectively increase the efficiency of decision-making.
