The paper first introduces the concept of organizational factors in the socio-technical system and the basic theory of Bayesian Network and then discusses the algorithm of structure learning of Bayesian network. A new algorithm base on dependency analysis is proposed to effectively reduce the number of detecting condition independence. It uses heuristic cutset searching algorithm and orients all the...
It is well known that human error is the key contributor in most marine accidents. Nevertheless, human error is not the cause of accidents or mishaps in the new view on human errors; it is the deeper trouble of the MMEM (Man-Machine-Environment-Management) system. The key point for human error analysis is to find out the connection between human error and the features of system elements, that is the...
In this paper, a new methodology, which integrates human factors analysis and classification system (HFACS) with Bayesian Network (BN), is proposed to assess the contribution of human and organizational factors in maritime accidents. As a means of making up the lack of quantitative analysis within HFACS, the integration of BN and fuzzy analytical hierarchy process (AHP) have been selected to estimate...
This study examined the effects of human redundancy arrangements on performance in the execution of computerized emergency operating procedures. It was found that there was significant difference in completion time but no significant differences in error rate or subjective workload between single-operator and two-operator setups. For the two-operator setup, an unbalanced workload was found. Team completion...
Considering the human-robot symbiosis in coming years, robots should be able to read human intention for natural and rational interaction with human beings. This paper proposes effective human-robot interaction (HRI) by reading the human intention using cognitive architecture. Proposed intention reading algorithm is inspired by mirror-neuron system and simulation theory which are the significant parts...
Human error plays a significant role in the failure of fastener-style tubular steel formwork-support(FTSF) during construction. Making full use of site investigation and references, the laws of human error occurrences during construction were gained. The probabilistic models for slip bearing capacity of right-angle couplers with different bolt tightening torques were obtained through experimental...
This paper presents a comparative study of perspectives from Western philosophy and Buddhism on higher cognitive functions of learning, knowledge and consciousness. This study actuated from the foundational work completed to develop an incremental learning algorithm with a knowledge acquiring disposition to address limitations in learning continuous data spaces. The morphological development of this...
Given prior human judgments of the condition of an object it is possible to use these judgments to make a maximal likelihood estimate of what future human judgments of the condition of that object will be. However, if one has a reasonably large collection of similar objects and the prior human judgments of a number of judges regarding the condition of each object in the collection, then it is possible...
We report on the development of a new simulation environment for use in Multi-Robot Learning, Swarm Robotics, Robot Teaming, Human Factors and Operator Training. The simulator provides a realistic environment for examining methods for localization and navigation, sensor analysis, object identification and tracking, as well as strategy development, interface refinement and operator training (based...
The analysis of human behavior is the basis of understanding many social phenomena. Based on a large database of taxi billing system, this paper provides an analysis of human mobility data in an urban area of using taxi services in Shanghai. By studying the spatial temporal data of taxi services, it shows that the distribution of running time interval is approximated by Power-law distribution. And...
This paper presents a new application that aims at improving communication and interactions between digital media and customers at a point of sale. Our system analyzes in real-time human behaviour while shopping. In particular, the system detects customer's interest in products and interaction such as people grabbing products. This system is based on a behaviour model. A video analysis module detects...
In recent years, there have been increasing researches on the irrational, subjective and perceptual aspects of strategic management, indicating the influence of perceptual factors such as value, emotion and feelings on strategic decision-making. Based on a rational perspective, current mental model is divided into belief and knowledge and is regarded as a mechanism to explain human perception, decision-making...
This paper presents a method to extract posture from a series sequence of contour images which were taken from the side of a person. We extract a cycle from the image sequence and confirm the body region, then extract the articulation points of a human body in each images of the sequence and normalize the frame number using cubic spline. In the experiment, we used 360 image sequences taken from 60...
Human capacity as well as institutional capacity and societal capacity determines the management capacity of the nature reserves. In China, the human capacity can not meet the requirements for the nature reserve protecting and the biodiversity conservation. This paper focuses on the current human capacity building in the nature reserves in order to promote their management effectiveness. We find that...
Digital instrumentation and control systems has been widely used to high-risk system, which changes the context influencing human performance, cognitive processes and human-machine interaction, thus lead to new human errors and error mechanism. This paper constructs the extended human error analysis model for analyzing the possible cognitive and action errors. And then human error causal factors are...
Subjective human factor engineering based on perception is a re-examine of ergonomics under the current situation, and also a complement and enrich for the gaps of ordinary ergonomics research. It gives emphasis on the necessity of subjective perception exploration besides ergonomics, analyzes the relationship between subjective perception factors and ergonomics, proposes a serious of relative concepts...
Natural physical space provides material basis for the birth and evolution of human beings and civilization. The progress of human society has created the cyber space. With the rapid development of information technology, the cyber space is connecting physical space, social space and mental space to form a new world - Cyber Physical Society. The way to explore the cyber physical society is different...
Human, machines and environment, three main factors contained in transport system in coal mines, and their impact on transport accident have been analyzed with system engineering theory of man-machine-environment in this article. Reasons and control of human mistakes, relationship between human and transport accident, analysis of machines' stability and fuzzy comprehensive evaluation have been deeply...
An effective motivation is an important way to promote staff's enthusiasm, initiative and creativity. Enterprises should adopt various motivation ways scientifically according to their real situation, change thinking model, to really establish an open motivation mechanism suit for the enterprises characteristics, era characteristics and staff objective demands, further to enable enterprises to be...
One of the factors that contribute to the enhancement of the effectiveness of a Virtual Environment (VE) is the capacity for visual short term memory (VSTM) or memory span. This paper describes an investigation of the memory span of Malaysian population for virtual environment design. Experiments were conducted where number, letters, word, and object or pictures were presented to test subjects. Nineteen...
