Tripod Beta is an incident and accident analysis methodology made available by the Stichting Tripod Foundation [1] via the Energy Institute.The methodology is designed to help an accident investigator analyse the causes of an incident or accident in conjunction with conducting the investigation.
CL-ESA exploits a document-aligned multilingual reference collection (e.g., again, Wikipedia) to represent a document as a language-independent concept vector. The relatedness of two documents in different languages is assessed by the cosine similarity between the corresponding vector representations.
In accident analysis it could be used to determine leading factors, post-incident. This model works like a flow chart to help show all processes and systems that may have effected the outcome of the incident. Failure Mode and Effect Analysis: This model uses a quantitative value to represent qualitative metrics like probability and severity ...
In science and engineering, root cause analysis (RCA) is a method of problem solving used for identifying the root causes of faults or problems. [1] It is widely used in IT operations, manufacturing, telecommunications, industrial process control, accident analysis (e.g., in aviation, [2] rail transport, or nuclear plants), medical diagnosis, the healthcare industry (e.g., for epidemiology ...
When used as part of an aviation hazard analysis, a "Likelihood" is a specific probability. It is the joint probability of a hazard occurring, that hazard causing or contributing to an aircraft accident or incident, and the resulting degree of loss or harm falling within one of the defined severity categories.
The critical path method (CPM), or critical path analysis (CPA), is an algorithm for scheduling a set of project activities. [1] A critical path is determined by identifying the longest stretch of dependent activities and measuring the time [ 2 ] required to complete them from start to finish.
The Tenerife airport disaster, the worst accident in aviation history, is a prime example of an accident in which a chain of events and errors can be identified leading up to the crash. [9] Pilot error, communications problems, fog, and airfield congestion (due to a bomb threat and explosion at another airport) all contributed to this catastrophe.
In Reason's model, the holes represent weakness or failure. These holes will not lead to accident directly, because of the existence of defense layers. However, once all the holes line up, an accident will occur. [6] There are four layers in this model: organizational influences, unsafe supervision, precondition and unsafe acts.
