Aiming to optimize the function allocation in typical combat tasks, this study proposes a cooperation strategy by integrating evolutionary game theory with system dynamics. Taking the crew and the automated system as different players in the evolutionary game model, the payment matrix is established. The evolutionary stable strategies of the replicator dynamic system are discussed under different evolution routes, revealing the time-variant dynamic features of the human–machine evolutionary game. Moreover, the system dynamics model is built to explain the internal interaction behavior and mechanism of the human–machine system. The simulation results indicate that the game with different initial system states can converge to different equilibrium points. The analysis of evolutionary processes with different model parameters demonstrates that the game strategies are more sensitive to the cost of an increase in mental workload and the payoff of an increase in trust and decision accuracy. With the adoption of the proposed function allocation strategy, the mental workload coefficient decreases by 36.09%, while the trust level and the decision accuracy increase by 33.59% and 38.83%, respectively. The proposed strategy highlights the significant impact of mental workload, trust, and decision accuracy on game approaches, and explains the internal interaction behavior and mechanism between evolutionary game strategies and the dynamics of the human–machine system. This study can provide a theoretical reference and modeling approach for human–machine cooperation in armored vehicles.</p>\u0000 </div>","PeriodicalId":55048,"journal":{"name":"Human Factors and Ergonomics in Manufacturing & Service Industries","volume":"35 3","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144140824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, the key tasks performed by operators during HRC were identified using the hierarchical task analysis, and a cognitive model was built based on information processing theory. This model breaks down the collaboration process into stages and identifies potential human errors at each step. Next, failure modes and effects analysis and evidence reasoning were applied to quantify the risk levels of these errors. Finally, the risks associated with human errors were measured, ranked, and compared with existing studies, and recommendations were made. The findings showed that the leading causes of safety risks in HRC are fatigue, illegal operations, error operations, misjudgments, and misperception. The perception stage of the process was found to carry the highest risk level, which means operators are more likely to make errors during the perception stage than during decision or execution, largely due to factors such as fatigue, distraction, and misperception.

Athletes are known to have higher pain tolerance than the general population, suggesting that they may manage pain differently. This study aims to elicit the “how” and “why” of acute pain management strategies when coping with sport injuries. A thematic analysis of qualitative data involved 12 injured elite athletes (EAs) to ascertain their drug and nondrug acute pain management strategies. Results showed 14 strategies relating to two functions: problem-focused and emotion-focused. Six problem-focused strategies aimed to change the relationship between an individual and his/her environment: (a) modulating activity; (b) seeking instrumental support; (c) goal setting; (d) encouraging oneself; (e) taking painkillers; and (f) reframing the perception of pain. Eight emotion-focused strategies aimed to manage emotional distress: (a) diverting attention; (b) acceptance; (c) relativising pain; (d) repeating negative thoughts; (e) ignoring pain; (f) seeking emotional support; (g) hoping and praying; and (h) self-blame. EAs were shown to favor three strategies: modulating activity, diverting attention, and seeking instrumental support. Results showed a repertoire of acute pain management strategies and the function each strategy served. The variety of pain management strategies reinforces the coping functions (Lazarus and Folkman 1984) and suggests newly-identified flexibility in coping with acute pain extending beyond previous results on chronic pain.

Despite its critical impact, few studies have focused on the cognitive characteristics of mind-wandering and its influence on situation awareness (SA). This study sought to bridge the research divide by utilizing electroencephalography (EEG) to explore the link between mind-wandering and brain activity, with the objective of establishing an objective means to monitor drillers’ mind-wandering. Utilizing the Situation Awareness Global Assessment Technique (SAGAT) in a simulated drilling monitoring task, we compared the states of 50 natural gas drillers before and after their shifts. Brainwave data were recorded and categorized into pre-shift and post-shift groups. Our analysis revealed a significant increase in mind-wandering post-shift, coupled with a notable decline in SA. This effect was especially pronounced during complex tasks, such as gas kick simulation videos, where response times increased and delta and alpha band power in the frontal lobes significantly rose. These findings suggest that mind-wandering adversely affects SA, particularly in complex task scenarios. The identified neural indicators offer objective measures of drillers’ cognitive states and can inform attention training and fatigue management strategies. By providing safety managers with real-time insights into workers’ attention, mind-wandering detection can help mitigate errors and enhance operational safety in high-risk environments.</p>\u0000 </div>","PeriodicalId":55048,"journal":{"name":"Human Factors and Ergonomics in Manufacturing & Service Industries","volume":"35 3","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143888894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these concerns, new standards mandate that electric vehicles, including ZEBs, be equipped with an acoustic vehicle alerting system (AVAS) emitting sound at low speeds, to make vehicles more detectable. However, developing an effective AVAS sound requires balancing safety and technical constraints with diverse stakeholder needs. Using codesign, this study conducted a series of risk-focused subject matter expertize workshops (<i>n</i> = 15), and a large user-experience focused participatory design workshop (<i>n</i> = 41) to inform the AVAS sound design. The latter included empathy and user journey mapping techniques, facilitating the collection of insights from various perspectives. Results revealed stakeholder preferences for an AVAS sound that was both alerting and positive, and embodied qualities like calmness, politeness, and vibrancy. The workshops allowed for refinement of sound design requirements, although challenges emerged in balancing conflicting preferences and managing technical limitations to create a sound that could be both perceptible and nonintrusive. This study provides a framework for the development of an AVAS sound that could capture a range of stakeholder needs and preferences and lays a foundation for AVAS sounds that enhance safety while being positively received.

This study applied a systems thinking-based risk assessment method to identify risks associated with hospital emergency evacuations. The Networked Hazard Analysis and Risk Management System (Net-HARMS) method was utilized to identify all credible risks in the hospital evacuation process during emergencies that could degrade optimal performance. Some of the key risks identified in the hospital emergency evacuation process included delays in assessing risks associated with evacuation procedures, failures or delays in forming and appointing an emergency evacuation and command team, and inadequate intra- and interorganizational coordination. Additionally, emerging risks were identified, such as delays in the evacuation process due to staff lacking sufficient information about the evacuation and incident command team members, as well as delays in receiving assistance from external organizations like the fire department and Red Crescent due to inadequate interorganizational coordination processes. These risks arose from the interactions between activities.
