How to identify critical chain?
Best insight from top research papers
Identifying the critical chain can be done using various approaches. One approach is to use a simulation data oriented approach to identify critical branches . This approach involves generating cascading failure chains and constructing a directed weighted graph to represent branch interactions. The hypertext-induced topic search (HITS) algorithm is then used to rate and rank the vertices of the graph, allowing for the identification of critical branches . Another approach is to use a simulation data based analytical approach, which involves sampling cascading failure chains and quantifying the interaction strength among failure branches . A directed weighted graph is constructed to depict the interactions among branches, and the HITS algorithm is used to rank the vertices and identify the critical branches . Additionally, an identification method based on path chains and transmission betweenness can be used, where a directed and weighted topological model is established and the transmission betweenness value of each line is calculated and sorted .

How can we determine which alarms are critical?5 answersCritical alarms can be determined by considering various factors. One approach is to use a machine-learning model trained to predict whether a non-critical alarm will develop into a critical alarm within a specific time period. Another method involves utilizing a dynamic alarm prediction algorithm that calculates the occurrence probability of critical alarms by accounting for the local interdependences among alarms using the n-gram model. Additionally, an electronic alarm management system can determine critical events by detecting trigger events, checking for scheduled events closely following the trigger event, and determining if the event exceeds a threshold importance score. Furthermore, improving the effectiveness of critical alarms can be achieved by reducing extraneous information for operators and ensuring clear expectations for response. Finally, in visually complex environments, acoustic parameters such as intensity and rate of change in intensity can be used to convey scalable levels of perceived urgency in auditory alarms.
