Risk

What is HAZOP?

• a hazard

• a structured and systematic technique for system examination and risk management.

• an unsystematic technique for system examination and risk management.

• A tv show

Which of the following is a disadvantage of HAZOP?

• Helpful when confronting hazards that are difficult to quantify,

• Built-in brainstorming methodology

• No risk ranking

• Systematic & comprehensive methodology

Which of the following is an advantage of HAZOP?

• No risk ranking

• Not required to explicitly rate or measure deviation probability of occurrence

• No means to assess effectiveness of existing or proposed controls

• No means to assess hazards involving interactions between different parts of a system or process

Which best describes Fault Tree Analysis?

• structured and systematic technique for system examination and risk management

• A TV show

• the identification and analysis of conditions and factors that cause or may potentially cause or contribute to the occurrence of a defined top event

• a simple risk assessment technique

Which of the following is NOT a component of Fault tree analysis?

• Gates

• Events

• Fences

Which of the following statement is True?

• Fault tree analysis uses a qualitative approach

• Fault tree analysis uses a quantitative approach

• Fault tree analysis can use a qualitative approach and a quantitative approach

• None of the above

Events Tree Analysis is:

• A Christmas Event

• a structured and systematic technique for system examination and risk management

• the identification and analysis of conditions and factors that cause or may potentially cause or contribute to the occurrence of a defined top event

• an inductive logic technique to model a system with respect to dependability and risk related measures as well as to identify and assess the frequency of the various possible outcomes of a given initiating event

Which of the following is an advantage of Events Tree Analysis?

• provides visualization of event chains following an initiating event

• operating scenarios must be anticipated by the analyst

• optimistic estimates of dependability and risk related measures can be obtained

• practical experiences of the analyst is necessary

Which of the following is a disadvantage of Events Tree Analysis?

• decomposition of large and complex systems into smaller, more manageable parts can be done

• needs practical experiences of the analyst

• assessment of multiple, coexisting system faults and failures as well as order dependent events;

• It allows for identification and traceability of failure propagation paths of a system

The events delineating the event sequences are usually characterized in terms of:

• Functional event tree, System event Tree, Phenomenal event tree

• Functional event tree, Christmas event Tree, Phenomenological event tree

• Functional event tree, System event Tree, Phenomenological event tree

• Functional event tree, Gate event Tree, Phenomenological event tree
