Recurring | unknown | (a) The software failure incident at Majorca airport involving the baggage sorting system was a one-time occurrence mentioned in the article. There is no specific information indicating that a similar incident had happened before within the same organization. (b) The article does not provide any information suggesting that a similar software failure incident had occurred at other organizations or with their products and services. |
Phase (Design/Operation) | design | (a) The software failure incident at Majorca airport, where about 2,000 bags were mixed up in a major malfunction with the airport's bag sorting system, was attributed to a suspected computer software glitch. This glitch caused the baggage sorting mechanism to mix up bags from different flights, leading to major delays and requiring staff to manually re-sort all bags [28452]. This aligns with a failure due to contributing factors introduced by system development or updates, as the glitch was likely a result of issues in the software design or implementation. |
Boundary (Internal/External) | within_system | (a) The software failure incident at Majorca airport, where about 2,000 bags were mixed up due to a suspected computer software glitch, can be categorized as a within_system failure. The malfunction with the airport's bag sorting system was attributed to a software glitch that caused the baggage sorting mechanism to mix up bags from different flights [28452]. This indicates that the root cause of the failure originated from within the system itself, specifically related to the software controlling the baggage sorting process. |
Nature (Human/Non-human) | non-human_actions | (a) The software failure incident at Majorca airport was attributed to a suspected computer software glitch that caused the baggage sorting mechanism to mix up bags from different flights. This malfunction led to major delays and the need for manual sorting of the bags, impacting hundreds of travelers [28452]. This indicates a failure due to non-human actions, specifically a software glitch in the baggage sorting system. |
Dimension (Hardware/Software) | software | (a) The software failure incident at Majorca airport, which caused delays and mix-up of about 2,000 bags, was attributed to a suspected computer software glitch. This glitch in the airport's baggage sorting mechanism resulted in bags from different flights getting mixed up, leading to major disruptions and necessitating manual sorting by staff [28452]. |
Objective (Malicious/Non-malicious) | non-malicious | (a) The software failure incident at Majorca airport, where about 2,000 bags were mixed up in the baggage sorting system, was attributed to a suspected computer software glitch. This glitch caused the baggage sorting mechanism to mix up bags from different flights, leading to major delays and inconvenience for travelers [28452]. This indicates a non-malicious software failure incident, as there is no mention of any malicious intent behind the glitch. |
Intent (Poor/Accidental Decisions) | poor_decisions, accidental_decisions | The software failure incident at Majorca airport, where about 2,000 bags were mixed up due to a suspected computer software glitch, can be attributed to both poor decisions and accidental decisions. 1. Poor Decisions: The article mentions that the baggage handlers at the airport had recently announced plans to begin strike action starting on August 1 over a dispute with their bosses regarding pay and working conditions. The decision to go on strike during the peak season when it would have the most impact on travelers and the airport can be considered a poor decision [Article 28452]. 2. Accidental Decisions: The software glitch that caused the baggage sorting mechanism to mix up bags from different flights was likely an unintended consequence of the software malfunction. This accidental decision led to major delays and inconvenience for travelers at the airport [Article 28452]. |
Capability (Incompetence/Accidental) | development_incompetence | (a) The software failure incident at Majorca airport, which caused about 2,000 bags to be mixed up in the baggage sorting system, was attributed to a suspected computer software glitch. This glitch led to bags from different flights getting mixed up, resulting in major delays and the need for manual sorting by staff [28452]. This indicates a failure due to development incompetence, as the glitch was likely a result of errors or oversights in the software development process. |
Duration | temporary | The software failure incident at Majorca airport, where about 2,000 bags were mixed up due to a suspected computer software glitch, can be categorized as a temporary failure [28452]. This is evident from the fact that the malfunction caused major delays to some flights, including those going to the UK, and staff had to manually re-gather and resort all the bags affected by the glitch. Temporary failures are typically caused by specific circumstances or events that introduce contributing factors leading to the failure, as seen in this case where the glitch in the baggage sorting system resulted in the mix-up of bags from different flights. |
Behaviour | crash | (a) crash: The software failure incident at Majorca airport was attributed to a suspected computer software glitch that caused the airport's baggage sorting mechanism to mix up bags from different flights, leading to major delays and the need for manual intervention to re-sort the bags [28452]. This aligns with the behavior of a crash where the system loses state and fails to perform its intended functions. |

The issue was specifically attributed to a suspected computer software glitch in the baggage sorting mechanism, which caused bags from different flights to be mixed up [28452]. (b) actuator: The incident did not involve an actuator error. The malfunction with the airport's bag sorting system was primarily due to a suspected computer software glitch that caused the baggage sorting mechanism to mix up bags from different flights, leading to delays and manual sorting by staff [28452]. (c) processing_unit: The software failure incident was related to a processing error. The problem at Majorca airport was attributed to a suspected computer software glitch that affected the baggage sorting mechanism, causing the mix-up of bags from different flights and resulting in delays for travelers [28452]. (d) network_communication: There is no mention of network communication error contributing to the software failure incident at Majorca airport. The primary issue was the suspected computer software glitch in the baggage sorting mechanism that led to the mixing up of bags from different flights and subsequent delays [28452]. (e) embedded_software: The failure was related to embedded software error. The software glitch in the airport's baggage sorting mechanism, which caused the mix-up of bags from different flights and resulted in delays, was attributed to a suspected computer software issue, indicating a problem with the embedded software controlling the system [28452]. |
Communication | unknown | The software failure incident at Majorca airport, where about 2,000 bags were mixed up due to a suspected computer software glitch, does not provide specific details indicating whether the failure was related to the communication layer of the cyber physical system that failed. The article primarily focuses on the baggage sorting system malfunction caused by a software glitch, without delving into the specific technical aspects related to the communication layer of the system. Therefore, it is unknown whether the failure was at the link_level or connectivity_level of the cyber physical system. |
Application | TRUE | The software failure incident at Majorca airport, where 2,000 suitcases were caught up in a malfunction, was attributed to a suspected computer software glitch that caused the baggage sorting mechanism to mix up bags from different flights. This aligns with the definition of a failure related to the application layer of the cyber physical system, which includes bugs, operating system errors, unhandled exceptions, and incorrect usage [28452]. |
