Human Error Probability

In complex industrial systems, human error has been cited as a cause or a contributing factor in accidents and disasters. The need for improved Human Reliability Assessment (HRA) methodologies that should be applied in Probabilistic Safety Assessments, ever since the early 1990s, has motivated a number of major activities in research and development worldwide. Therefore, the main purpose of this paper is to show the practical application of Human Error Assessment and Reduction Technique (HEART) for HRA in Electric Power Company of Serbia (EPCS). The usefulness of this technique for HRA has been approved in a case study of an accident which occurred during a repair on a 10/0.4 kV steel lattice tower “Maričiće“, Kuršumlija (jurisdiction of EPCS, ED “Jugoistok”, Nis, Serbia). For the purpose of this study, a database on work-related injuries, accidents, and critical interventions that occurred over a 10-year period was created. The research comprised an analysis of 1074 workplaces, with a total of 3997 employees. The case study performed at the EPCS confirmed that the HEART is based on knowledge of human activities and relies on expert opinion to determine the Error Producing Condition (EPCs) that affected the situation. The HEART can be used in different industrial systems, as a risk assessment, accident investigation and design tool. In addition, it is a relatively fast tool for assessment of human error probability that is easily applied and understood.

Advantages And Disadvantages

The authors have recently developed a microworld, a simplified process control simulator, to simulate a nuclear power plant. The microworld provides an environment that can be readily manipulated to gather data using a range of participants, from students to fully qualified operators. Because the microworld represents a simplified domain, it is possible to have more precise experimental control compared with the complex and confounding environment afforded by a full-scope simulator. In this paper, we discuss collecting human reliability data from a microworld. We review the generalizability of human error data from the microworld compared to other data sources like full-scope simulator studies and compare advantages and disadvantages of microworld simulator studies to support human reliability data collection needs.

New demands on modern manufacturing systems have emphasised the need for higher levels of overall system reliability. The main focus of this paper is that of the reliability of manufacturing personnel and the way in which this interrelates with overall system performance. A framework - Human Error and Disturbance Occurrence in Manufacturing Systems (HEDOMS) is proposed, which integrates human reliability with overall system performance, relating human error with disturbance occurrence and handling. The HEDOMS framework has been extended into a toolkit to enable the identification of potential for human error and disturbance occurrence in manufacturing systems, as well as the definition of suitable error reduction measures.

The Road

Human error has played a critical role in the events precipitating the road accidents. Such accidents can be predicted and prevented by risk assessment, in particular assessing the human contribution to risk. As part of the Human Reliability Assessment (HRA) process, it is usually necessary not only to define what human errors can occur, but how often they will occur. Lack of understanding of the failure distribution characteristics of drivers on roads at any given time is a factor impeding the development of human reliability assessment and prediction of road accidents in order to take best proactive measures. The authors developed the complete investigation methodology for crash data collection. Furthermore, they have experimentally tested the proposed predictive behavioral characteristics of drivers in light of their instantaneous error rate over the course of driving period to assist processing and analysis of data collection as part of risk assessment. The findings of this research can assist road safety authorities to collect the necessary data, to better understand the behavioral characteristics of drivers on roads, to make more accurate risk assessments and finally to come up with right preventive measures.

Machine Interaction

Human reliability has been a focus in system reliability and safety researches since 1960s, and now human factor has become an increasingly important reason which affects system reliability. Numerical control machining system characterized by man-machine interaction can be applied to automatic parts machining with high efficiency. However, professional and technical staffs are still needed for clamping, positioning, inspection and others. So there is no doubt that the quality of the parts might be influenced by personnel behaviour. What’s more, on-site staff is responsible for handling potential fault directly. The study on human error plays an important role to ensure the quality and reduce industrial accident. Holistic Decision Tree (HDT) is a dynamic Human Reliability Analysis (HRA) method, emphasizing the wholeness of man-machine interaction. This paper tries to use an optimized HDT method to investigate human reliability in numerical control machining system. In order to obtain a rational order of the importance of each IF, this paper incorporates entropy weight method to the conventional expert method to determine the relative weight value of each human behaviour influence factor (IF), and finally calculates the human error probability (HEP).

Human Operators

Operator have considerable contribution in the operation of the system trough its role in the completion of their work. Therefore it is important to know the operator’s reliability (human reliability). The levels of human reliability is determined by calculating the potential in making mistakes, known as human error. Human error is influenced by the inadequate system design, the working bad situation, the high complexity of the work, the characteristics of human behaviour, the mental and physical fatigue, the working environment and organizational policies. The main objective of this study was to analyze the reliability of the human operators to control the occurance of human error. This study was an observational with cross-sectional approach. The study was conducted on 14 of operators maintenance machine in PT. Tjokro Putraperkasa. Data were collected by means of interview and observation. Data were obtained using Hierarchical Task Analysis (HTA) and Standardized Plant  Analysis  Risk  Human  Reliability  Assessment  (SPAR-H).  The  result  showed  that  most  (80%)  of  the operators did not wear Personal Protective Equipment (PPE), possible were widely found in preventive maintenance machine bubut, the high score (HEP= 0,0477) of human unreliability was found in operators working intruction in machine bubut, hobbing and CNC, as whole the system reliability was still low, and the majority (80%) of operators were still unreliable in doing their job.Keywords:human error, human reliability, SPAR-H.
