HECKMANN - Risk aware decisions Flashcards
The ability of a system to return to its original state or move to a new, more desirable state after being disturbed is called robust-ness.
False
Traditional risk management addresses the assessment and management of natural and man-made disasters, major disruptions and market shifts, as well as common deviations and market volatility.
False
Which of the following concepts co-define resilience?
robustness & adaptability
The core characteristics of supply chain risk are
disruptive trigger, vulnerability, time, decision maker’s objectives and attitude
A Black Swan refers to:
an event that is not represented within a probability distribution
The value-at-risk (VaR) accounts for properties of the loss distribution beyond the confidence level.
False
The conditional-value-at-risk (CVaR) represents the expected loss beyond the value-at-risk (VaR).
True
Suppliers with very low Time-to-survive (TTS) values indicate
that more accurate Time-to-recovery (TTR) evaluation and closer monitoring for risk exposure are required
Contemporary, traditional risk analysis often refers to the risk definition R = PxS (R= risk, P = probability of an event, S = severity of an event). This definition often results in a misinterpretation of
probability
The analysis of potential disruptive triggers implies:
the identification of those processes that are affected by the trigger.
Suppliers with high total spend and high-performance impact are
strategic important suppliers that should be focused by long-term partnerships and risk- diversification contracts,
The higher the Time-to-Survive (TTS) compared to the duration of a disruption, the higher the risk
False
The value-at-risk (VaR) accounts for properties of the loss distribution beyond the confidence level of alpha
False
The conditional-value-at-risk (CVaR) represents the expected loss beyond the value-at- risk (VaR)
True
calculate the Value-at-Risk (VaR) at a 95% confidence level (alpha = 5%)
1.) Determine the cumulative probabilities: Add up probabilities of Scenarios until you reach or exceed the desired confidence level (95%)
2.) Identify the loss value at the desired cumulative probability (ablesen)
3.) VaR gefunden
