A Key Event Path Analysis Approach for Integrated Systems

Table 3

Event paths and meanings of the EWR system.

Routess	Meanings
𝜎1=P_StartWork;P_Search;P_SearchData;P_Capture;P_CaptureData;	EWR transmits reports successfully.
P_Trace;P_Traced;P_SteadyTrace;P_Report
𝜎2=P_StartWork;P_Search;P_NotSearched;P_NoTime;P_Fail	EWR works overtime and does not find any threats.
𝜎3=P_Search;P_NotSearched;P_TimeEnough	EWR searches again when nothing found.
𝜎4=P_Search;P_SearchData;P_Capture;P_NotCaptured	EWR captures again when nothing captured.
𝜎5=P_Trace;P_Lost;P_AddSearch;P_AddSearched	EWR add-searches threats after lost them.
𝜎6=P_Search;P_SearchData;P_Capture;P_CaptureData;P_Trace;	EWR searches again after not add searched.
P_Lost;P_AddSearch;P_NotAddSearched
𝜎7=P_Trace;P_Traced;P_SteacyTrace	EWR tracks steadily.
