2. 2 Introduction MERA is a Decision Support system MERA is a Decision Support system A decision support system (DSS) is a computer program application that analyzes data and presents it so that users can make decisions more easily. It is an "informational application" (in distinction to an "operational application" that collects the data in the course of normal operation). A decision support system (DSS) is a computer program application that analyzes data and presents it so that users can make decisions more easily. It is an "informational application" (in distinction to an "operational application" that collects the data in the course of normal operation). MERA not only supports decision making but also serves as a Error Analyzer to forewarn any impending threat. MERA not only supports decision making but also serves as a Error Analyzer to forewarn any impending threat.

3. 3 Problem & Suggested sol.n… Numerous untraceable errors occurring in Medical field Numerous untraceable errors occurring in Medical field No existing efficient system which can predict the errors based on history No existing efficient system which can predict the errors based on history Detect Errors by analyzing the intricacies even before they occur Detect Errors by analyzing the intricacies even before they occur Framing the current pattern to see if it is perilous by comparing it to the previous pattern of errant behavior Framing the current pattern to see if it is perilous by comparing it to the previous pattern of errant behavior

5. 5 Features Autonomous agents: allow decoupling of the main functionality of Error Report and retrieval from analysis and learning Autonomous agents: allow decoupling of the main functionality of Error Report and retrieval from analysis and learning Learning: Learns the current pattern Learning: Learns the current pattern User based output User based output Warning generation: Warns the System manager immediately after he logs in if the system discovers that the current error pattern might lead to a dangerous pattern Warning generation: Warns the System manager immediately after he logs in if the system discovers that the current error pattern might lead to a dangerous pattern

10. 10 User Agent The Interface between the system and Client The Interface between the system and Client It is what the client sees as MERA It is what the client sees as MERA Authenticates the User Authenticates the User Recognizes the user Designation and passes the designation to Data retrieval component. Recognizes the user Designation and passes the designation to Data retrieval component.

11. 11 Continued…. Reporting: It Passes the reported error to the Service Agent and also Records the error. Reporting: It Passes the reported error to the Service Agent and also Records the error. Analysis: It retrieves the data from the database. User has an option to chose the criteria of data analysis. Analysis: It retrieves the data from the database. User has an option to chose the criteria of data analysis. eg: Based on Time, Department, etc.

12. 12 Service Agent Acts only during Reporting Acts only during Reporting It receives the report from User Agent and tries to learn the current pattern. It receives the report from User Agent and tries to learn the current pattern. Compares the current pattern to verify if it is moving to some error pattern recorded in history. Compares the current pattern to verify if it is moving to some error pattern recorded in history. If a pattern match occurs, it shall throw a warning message which is stored by the User agent to inform the manager. If a pattern match occurs, it shall throw a warning message which is stored by the User agent to inform the manager.

13. 13 Support This is a component which helps the interaction with the database. This is a component which helps the interaction with the database. Analysis: the criteria from the user and his designation are passed in to Support by User Agent. Analysis: the criteria from the user and his designation are passed in to Support by User Agent. Based on the Designation, the data is retrieved from the database. Based on the Designation, the data is retrieved from the database.
