針對地鐵應急演練、信號故障監控、輔助故障處理等應用具有系統實時性要求較高、
數據傳輸量較大等特點，利用Ajax模式和MVC架構相結合的方法設計并實現了一種采用
Ajax + Struts + Hibernate框架的地鐵應急演練與輔助決策系統。該系統結合了Ajax技術快速異步響應和MVC架構成熟穩定等的特點。實驗表明：采用該架構能有效地降低客戶端與服務器的通訊量，顯著提高系統性能。

Abstract: Metro emergency drilling, signal fault monitoring and decision-making support system has a higher real-time requirements and a greater volume of data transmission contrast with other system. This paper presents a method to solve all these problems based on the integration of Ajax and MVC model. The System combines the technology of Ajax, Struts and Hibernate. The experiment indicated that in the method proposed, communication between browser and server is reduced and the delay of pages refresh has become much lower than before. This framework improves system performance significantly.
