Повний текст джерелаNaval Aviation is in the midst of a major transformation as it attempts to come to terms with the demands of maintaining operational readiness in the face of diminishing budgets and reduced manning. Diminishing operating and procurement budgets mean that Naval Aviation is for the most part "making do" with existing aircraft. Over the past decade, one in four Naval Aviation mishaps were partially attributable to maintenance error. The present operating environment underscores the need to address maintenance error and its causes. The current study accomplishes three things. First, it evaluates 470 Naval Aviation mishaps with distinct maintenance error correlates. Second, it categorizes those errors using a taxonomy based upon current organizational and psychological theories of human error. Third, it mathematically models the consequences of these errors and uses the models to (a) predict the .frequency with which maintenance-based mishaps will occur in the future and (b) approximate the potential cost savings from the reduction of each error type.

Повний текст джерелаCoders of databases repeatedly face the problem of checking their Structured Query Language (SQL) code. Instructors face the difficulty of checking student projects and lab assignments in database courses. We collect and categorize common MySQL programming errors into three groups: data definition errors, data manipulation errors, and transaction control errors. We build these into a comprehensive list of MySQL errors, which novices are inclined make during database programming. We collected our list of common MySQL errors both from the technical literature and directly by noting errors made in assignments handed in by students. In the results section of this research, we check and summarize occurrences of these errors based on three characteristics as semantics, syntax, and logic. These data form the basis of a future static MySQL checker that will eventually assist database coders to correct their code automatically. These errors also form a useful checklist to guide students away from the mistakes that they are prone to make.

Повний текст джерелаNos últimos anos ocorreram situações que demonstram que os acidentes em organizações de elevada fiabilidade têm consequências catastróficas que precisam de ser contidas ou evitadas. As medidas para a contenção e prevenção do erro estão estabelecidas nesse tipo de organizações, mas focalizam-se em evitar as consequências negativas dos erros, não analisando as consequências positivas dos mesmos (quando existem). A literatura aponta como consequências positivas a aprendizagem, a inovação e a resiliência. O trabalho conclui que de forma conceptual a consequência positiva dos erros é um aumento da Segurança Organizacional através de processos de melhoria associados à Aprendizagem Organizacional. O erro humano não deve ser primariamente entendido como a principal causa dos acidentes, mas antes como uma possível consequência da atividade organizacional. Foi necessário compreender como (How) ocorre e porque (Why) ocorre o erro organizacional; e, ainda, qual a relação entre os diferentes níveis de erro (humano, de equipa e organizacional) e os fatores organizacionais. Esta abordagem transportou o investigador para a necessidade de uma análise aprofundada do conceito de condições/erros latentes. O conhecimento das causas primárias de um incidente/acidente poderá levar a que se criem indicadores que sirvam de alertas em situações futuras e/ou se alterem essas mesmas condições para que se evitem situações idênticas. Verificou-se neste trabalho que cada incidente/acidente, depois de estudado, é uma fonte de informação absolutamente essencial para a melhoria do sistema. No entanto, existem outras fontes que necessitam de ser mais estimuladas, nomeadamente, o reporte de ocorrências e a correspondente análise e partilha de resultados na Organização. A investigação recorre a uma metodologia qualitativa e os resultados aplicam-se apenas à Organização em estudo. O modelo final explica como através do erro de manutenção aeronáutica, na Força Aérea Portuguesa, se aumenta a Segurança Organizacional.
In recent years, situations have occurred which demonstrate that accidents in High Reliability Organizations have catastrophic consequences that need to be restrained or avoided. Measures to contain and prevent errors are established in this type of organizations, but focus on avoiding the negative consequences of errors, thus not analyzing their positive consequences (when they exist). The literature points to positive consequences of learning, innovation and resilience. The study concludes that, in a conceptual way, the positive consequence of the errors is an increase of the Organizational Security through processes of improvement associated with the Organizational Learning. Human error should not be primarily understood as the main cause of accidents, but rather as a possible consequence of organizational activity. It is necessary to understand how and why organizational errors occur; and the relationship between the different levels of error (human, team and organizational) and organizational factors. This approach transported the researcher to the need for an in-depth analysis of the concept of latent conditions / errors. Knowing the root cause of an incident / accident may lead to the creation of indicators that serve as warnings in future situations and / or change the same conditions, so that similar situations are avoided. It was verified in this study that each incident / accident, once studied, is an absolutely essential source of information for the improvement of the system. However, there are other sources that need to be more stimulated, namely the reporting of occurrences and the corresponding analysis and sharing of results in the organization. The research uses a qualitative methodology and the results apply only to the organization being studied. The final model explains how the Organizational Safety is increased, through the aeronautical maintenance error in the Portuguese Air Force.

Past studies on the human factors related to aviation incidences focused mainly on flight crews and air traffic controllers, and few were on the aircraft maintenance issues. With the technological advances in designing and manufacturing aircrafts, reliability and safety of airplanes has been drastically increased, while the importance of aircraft maintenance is not given equal emphasis. In this study, we collected maintenance related cases in the last three years from the focal company and analyzed possible grouping of all identified causes for human errors to see if there were possible correlations. We further interviewed people who were involved in the cases to gather their opinions of possibly ignored caused that were undetected when the cases were originally discussed in the focal company. The results show that some possible causes for human errors were missing from the previous analysis and some managerial recommendations are provided.

In spite of the implementation of modern technology and an efficient control procedure to improve equipment, the deterioration of the production process is unavoidable in most manufacturing industries. Inspections and maintenance activities are performed in virtually every production system. In this study, we construct models that allow us to economically determine the optimal inspection/disposition strategy for a batch of items produced by a machine that is subject to random breakdowns. We use the proposed mathematical framework to explore the issues relating to inspection errors, rework, preventive maintenance level, and minimal repair. The operational implications of the optimal strategy are then analyzed with a selected set of numerical results. We formulate dynamic programming of optimal strategy for two types of inspection activities: inspection of products and inspection of production systems. For inspection of products, we develop models of off-line inspection for a deterioration process having general shift distribution with an increasing hazard rate. To have an off-line inspection following an unreliable process is an appropriate quality assurance tactic in certain systems. Previous work has dealt exclusively with finding the point where the process shifts away from its in-control state to an out-of-control state. Our models incorporate the economic aspects of the inspection activity and of the two types of product inspection errors. Ignoring the true economics of quality assurance can result in unnecessary costs and time delays. We determine the first unit inspected and the average number to be inspected in a batch. We also study the effect of allowing rework on the optimal inspection strategy. For inspection of production systems, we generalize the classical economic production quantity model to consider possibilities of preventive maintenance errors and minimal repair. Our model solves simultaneously the optimal number of inspections, the duration of the first inspection interval, the economic production quantity, and the preventive maintenance level. Despite the strong interdependence between production, quality and maintenance, these three main aspects of any manufacturing system are traditionally modeled as separate problems. Few attempts have been made to integrate them in a single model that captures their underlying relationships. Our study essentially explores models for the joint optimization of production quantity, quality assurance inspections, and maintenance level. Our results demonstrate that these different but interrelated aspects of a manufacturing system can be captured rigorously in a united framework. Numerical simulations also illustrate the importance of viewing all theses decisions concerning core manufacturing processes in an integrated manner, rather than as a set of separate decisions.

Aircraft maintenance is a process of ensuring that all systems on the aircraft continue to perform their intended functions at the level of safety design and reliability. Without the contribution of maintenance personnel, the aviation industry can not operate, however, due to job characteristics, line maintenance tend to have higher error rate than other maintenance departments, which in turn poses a threat to flight safety. Human error is the result of interactions between individuals, workplaces, and organizational factors. It often has a negative impact on the job performance of maintainer, and may even result in flight incidents. Therefore, this study intends to study the relationship between human error and the organizational behaviors from the aspects of job satisfaction and organizational commitment of the line maintenance staff. This study conducted a questionnaire survey to collect data from the line maintenance staff of a major airline in Taiwan. A total of 241 valid questionnaires were collected. The results of statistical analysis revealed that the main error factors influencing the line maintenance staff include “Fatigue”, “Pressure”, “Stress” and “Destructive-Workplace Norms”.Job satisfaction has a negative impact on “Lack of Communication” , ”Leak of Awareness” , “Pressure” , “Fatigue” , and “Destructive-Workplace Norms” among human errors.Organizational commitment have a negative impact on “Lack of Communication” , “Leak of Awareness” , “Fatigue” , “Pressure” among human errors.

Повний текст джерелаBefore this study took place, the social psychology perspective of Attribution theory was yet to be fully utilised in South African research within the maintenance error landscape. Attributional approaches see the person on the street operating like a scientist, obtaining information from his or her social surroundings and discerning the causes and consequences of ongoing behavioural and environmental events (Harvey et.al.,1976). It is very possible that due to the unique South African socio-political and economic landscape, strongly influenced by Apartheid, new combinations of known and unknown error attributions are at play, that are unique to this landscape and have not yet been studied or uncovered. Thus, a better understanding of the South African landscape, through a study such as this, could have serious cost benefits to maintenance companies, benefits to staff in terms of reduced risk of injury, as well as form the basis of improved policies, procedures and equipment. Twenty-five team leaders and 125 minor maintenance staff at a South African Aircraft Maintenance Company formed the population group from which the sample for this study was drawn. Within each group, 5 individuals were interviewed on a personal basis. Further, for each group, one focus group was carried out consisting of two and four individuals respectively. The individuals who participated in the focus groups were different to those who participated in the interviews. In total 28 percent of team leaders participated in the study and 7 percent of maintenance staff, which calculates to just over 10 percent of minor maintenance employees at the organisation involved. The Qualitative data acquired through this in-depth interview and focus group discussion process, and subsequent transcription was coded and analysed using Thematic Content Analysis. Content analysis is a research technique for making replicable and valid inferences from data to their context (Krippendorf, 1980). The discussion of primary error attributions comparing maintenance staff and team leaders, focussed on the predominant primary error attribution theme and related attributions under the descriptor Organisational Culture which included both the dimensions of employee motivation and managerial culture. Finally, results of secondary error attributions comparing maintenance staff and team leaders raised the discussion around the theme, Tools and Equipment. This research is an exploratory study that brings together the field of attribution theory and maintenance error. Its main strength is that it provides a theoretical framework, upon which is based a methodology that explores the primary and secondary error attributions made by employees for maintenance errors in their work environment. In other words, it is felt that this methodology can be implemented in a range of maintenance environments to unearth the error attributions of staff in that environment. Information such as this is very beneficial to companies and organisations in their planning, strategising, problem solving and general organisational development.

Today the globalization has brought rapid development. It is expected that airline transportation volume in the future will be increased on a large scale. The ‘flight safety” and “economic effects”—the two pressures which the counterpart airline companies undertake will also be increased. How to improve flight safety is the issue which airline enterprises should face and explore. According to the statistics of International Air Transport Association (IATA), 80% of all the accidents related to flight safety are concerned with human error. However, most enterprises have not made a detailed analysis and taken action to deal with them regarding these records and data to find out the main factors of human error. This study uses “Maintenance Extension of the Human Factors Analysis and Classification System (HFACS-ME)” as the framework of theories. It is aimed to study the target airlines whose aircraft line maintenance departments caused abnormal incidents because of human error in the recent three years (2009-2011). The study will make an independent analysis of their maintenance paper reports and explore the sub-items of different levels that affect aircraft maintenance, that is, the human factor related to human error. After the research results of statistics and certification, the study has discovered that the first three sub-items are respectively the first-level “Judgment/Decision-making”, the fourth level “Inadequate processes” as well as the third-level “Inadequate training/Preparation”, which shows that the errors caused by “Judgment/Decision-making” is the foremost key factor of human factors concerned with airplane maintenance. In addition, through the association analysis of different levels, the study will find out the obvious genres and invariables existing between high levels and low levels, use the τ coefficient brought forth by Goodman & Kruskal as the inspection vector with the purpose of finding the path of levels and also use Odds Ratio to display the intensity of association. With the results obtained from the above-mentioned inspection and analysis, we can understand the mutual influences of high levels and low levels. The ordering of human factors and the association of between-levels derived from this study can be provided to airline companies that under the circumstances of limitation of resources, can focus on the risk factors of management and apply it to Safety Management System (SMS) with the hope that the occurrence probability of human error can be reduced to the minimum.

This paper proposes an optimal policy which integrates production, inspection, maintenance, inspection time and inventory problem to consider imperfect rework and maintenance error are allowed for an imperfect production process. We find the optimal inspection interval, the expected number of inspection and economic production quantity of the maximum expected profit per unit. The production process may turn into “out-of-control” state from “in-control” state because of the human behavior or the machines. If the production process is “in-control” state, we execute preventive maintenance, system age is related to the level of preventive maintenance. When the production process is “out-of-control” state, some defective items are produced. Assuming some of the defective items can be reworked and turn to well item, others can not be reworked and turn to waste item. In conclusion, we investigate the benefit of the preventive maintenance in the deteriorated system of the production process. Numerical examples illustrate the effect of preventive maintenance level, imperfect rework, inspection time and maintenance error on the expected profit per unit.

Abstract Subject:Risk Perception and Risk Propensity Affect Human Error factors of Aircraft Maintenance -Case Study Student:Wen Chuan Liu Aviation Safety is always the ongoing goal to human's flight activities, however, air crash is for a variety of reasons which includes: the design and manufacture of an airplane, the maintenance schedule, the weather, the Air Traffic Control factor and pilot's operation process as well as the organization culture and decision making of the Civil Aviation Authority or of the Air Lines. The "Human" Error Factor that could be prior prevented or could be an avoidable mistake is widely involved in complicated operation process or just has been in the environment. Reasonable decision makers assume that we humans are reasonable and objective and will certainly make decision between the biggest benefit and the smallest loss. However, the school of behavior found out through empirical research (Kahneman & Tversky, 1979) that we humans just won't make decision base on a reasonable, objective or econometric way to search for their final goal but to make decision through person preferences. Risk means the uncertainty of life and with an outcome to influence human life; risk focuses on future possibility and future uncertainty. Therefore, main purpose of this research is to discuss how the different Risk Perception and Risk Propensity from maintenance crew can influence the factor of Human Error. In summary, this research discovers that: (1) Other than education element of population variable, there is also with great difference to Risk Propensity among different genders, organizations, departments, ages and numbers of years in employment. (2)There's no big difference between the degree of familiarity and Risk Perception, and an inverse correlation between organizational control and Risk Perception; Risk perception, Risk Propensity and Human Error are all in positive correlation. (3) There is obvious difference of Risk Perception between High/Low degree of familiarity or High/Low degree of organizational control from/to maintenance crew. (4) There is obvious difference of Human Error between High/Low degree of Risk perception or High/Low degree of Risk Propensity from maintenance crew. (5) Risk Perception will not influence Human Error by the interference of Risk Propensity. (6) The degree of familiarity and organizational control can predict and explain Risk Perception. (7) Risk Perception and Risk Propensity can predict and explain Human Error. Key Words: Familiarity, Organizational Control, Risk Perception, Risk Propensity, Human Error

Today, although many works can be replaced by machines, the maintenance tasks still rely on people with unexpected mistakes at the same time. Usually the causes of these mistakes are due to a sequence of errors; however, if only reviewed the direct active errors without further investigation of indirect latent errors, the similar accident may happen again. In this study, an analysis method is developed to find out the most important latent human error factor. By using Root Cause Analysis (RCA) method as the basic logic, Human Factor Analysis and Classification System (HFACS) as the factor source and daily check of aviation maintenance as a case study, this research dismantled the maintenance process and collected the data of each procedure. After designing the questionnaire by the preliminary factors and surveyed 115 experienced maintenance operators to do the analysis, the importance ranking of factors allows the airline to specifically design improvement plans directly, and the reference values have also been set for the use to related researches. Here comes some sum up of conclusions in this study. First, the most important active factor is “Task execution error”, and the latent factor which has the most influence is “Maintenance capability.” Second, the combination of RCA and HFACS is an easy use method to investigate the causal inference and build the factor connection of collected data. Third, the research outcomes suggested not only the results caused by latent errors and the improvement direction, but the priorities for the improvement and the reference values of each active error factor to each step.

As we know, the work contents of flight safety are inclusive of everything, we can subdivide these three major accomplish causes classification: human error, environment (atmosphere)factor and mechanical (maintenance)factor which made the accident events happened into seven causes: crews, aviation control, meteorological phenomena, station management, navigational matters operation of the aviation company, the function of the airplane and maintenance, as reviewed those severe events and death accidents which happened during 1959-1996 in international civilian aviation scope, we could analysis and had this conclusion which human error occupied 73.3% among total events, consequently, human error is the most major reason of the airplane accident. First step of this research was collected the primary statistical materials of flight safety events from ROCAF, and proceeded analysis at flight safety events classification and the beginning cause of accident to realize the relationship between each flight event which occurred nearly several years in ROCAF; besides this there is an open-up questionary which made basically according to 12 causes which possessed potential possibility of human error on aircraft maintenance brought up by Canada Transportation Department, and joined with 4 questions about the application situation of the ROCARE, offered to the technician in T.F.W. of the ROCAF to carry out questionary investigation of the human factor which might cause human error and the application effect of ROCARE, in order to evaluate the difference concerned about among different technician types in T.F.W. of the ROCAF for the cause of technician mistake. This research took the technician whom working in T.F.W as the object of study, the effective retrieved rate for the questionary is 89.02%, totally about 527 persons whom had been sieved out as the research sample, through various statistics and analysis method to examine and analyze these retrieved questionary, we finally got the conclusion as follows: 1.There are obvious differences among each grade of the dangerous flight events and their causes, the mistake made by the pilot was the first reason inside of these causes which we found in the first, second and third grade events, but for the fourth grade events the major cause is mechanism factor. Analyzing the amount for each grade of dangerous flight events according to the human factor, it was found that there is no obvious difference for the amount between airman errors and technician errors, but the error rate for airman and technician became different according to the different grade of dangerous flight events, the pilot error is higher than the technician errors in the first, second and third grade events. And the technician errors in the fourth grade events, it was found that the unit which performing direct maintenance made more errors than the unit which performing indirect maintenance. And for the unit which performing direct maintenance, it was found that I/L maintenance unit made the most errors, the on-line unit and performing unit was less than, and for the cyclic-check unit was more less than. 2.The common point of view at the main reasons which causes human error made by ROCAF technician were fatigue, complacency, lake of awareness, pressure and lake of professional knowledge. Technicians also have difference according to their group characteristic as their age, marriage, job, working seniority, safety training, rank, military educational background and etc. 3.Nearly 50% technician aware of ROCARE which established by the ROCAF, but less than 10% of them had ever used this system; And nearly 50% of them think this Active Flight Safety Reporting System can help the prevention of maintenance error and improving the aviation safety, but there are only 30% of them who will trust that the Active Flight Safety Reporting System can make these targets as: keeping secret, free of responsibility, neutral, trustworthy, professional. It conveys that technician aware of the existence of this system and trust it’s function of helping to prevent maintenance error and to improve the aviation safety, but they don’t think the establishment unit can do the good job at some measures as keeping personal information secret and etc., not even share their personal experiences.

The study of human error in maintenance of the impact of Air Force aircraft, and landing gear systems, flight operations department and maintenance of the engine system operators is analyzed, the questionnaire structure is the core concept SHELL mode, the reason for classification of human error induced for the LS (people to software), LH (people to hardware), LE (people to the environment), L (of their own limitations), LL (people to people) in five dimensions and the layer is divided into 17 criteria, the use of multi-criteria decision analysis theory of AHP, CRITIC method, the standard deviation method and Grey method were seeking their weights, the weight of AHP by subjective analysis and found that the major factor inducing human error is the whole L (of their own restrictions) in the first place, which replaced the "staff of the psychological state of" maximum value for the weights, showing that psychological adjustment to staff the root causes of human errors induced. Supplemented by the objective weight CRITIC method, the standard deviation method and the weight of ash analysis of the implementation of related laws, there is a significant causal relationship exists, the gray relational method is obtained by "lack of equipment or hand tools," the first sort, showing that a lack of equipment, a great impact, maintenance staff to achieve the task, as must use non-standard hand tools to perform the repair, which will indirectly causing psychological stress, inconsistent with hand tools to perform the repair, construction quality be compromised, resulting in more effective, even derivative accident unfortunate.

Повний текст джерелаO presente trabalho centra-se no estudo das condições técnicas e organizacionais em que se realizam as operações de manutenção de aeronaves na aviação civil, em Portugal continental, bem como nos efeitos dessas condições sobre as capacidades funcionais e sobre o desempenho dos técnicos de manutenção. Serão analisados os vários tipos de fadiga, como eles se instalam, os constrangimentos introduzidos pelo trabalho noturno, quais os erros mais comuns que daí resultam e quais os fatores que mais condicionam o desempenho dos técnicos nestes ambientes, que são caracterizadamente complexos. A partir desse estudo base, pretende-se determinar qual o contributo da fadiga (física e mental) e da organização do trabalho para a ocorrência de erros e quais os riscos daí decorrentes no que se refere às condições de segurança dos próprios trabalhadores da manutenção e, indiretamente, dos passageiros das aeronaves. São também abordados os aspetos relacionados com formação e treino e a sua importância e impacto na indução de stress nos técnicos de manutenção de aeronaves. Por último, será ainda analisado em que medida a vulnerabilidade relativamente à fadiga e ao stress apresenta diferenças significativas em função: (1) da antiguidade: afetam mais as pessoas com maior antiguidade e menos as pessoas com menor antiguidade? (2) da idade: afetam mais as pessoas mais velhas do que as mais novas? De modo a responder às questões de investigação e procurar a existência de sintomas de fadiga entre os Técnicos de Manutenção de Aeronaves (TMA), foi disponibilizado, via Internet, um questionário individual e anónimo, quer relativamente a cada sujeito, quer relativamente à empresa onde o TMA trabalha. Foram abordadas 15 empresas que prestam serviços de manutenção a aeronaves em Portugal continental. O questionário teve 55 respostas, que foram a base do trabalho apresentado.
This paper focuses on the study of the technical and organizational conditions under which aircraft maintenance operations are carried out in civil aviation in mainland Portugal, as well as the effects of these conditions on the functional capabilities and performance of maintenance technicians. The various types of fatigue will be analyzed, how they settle, the constraints introduced by night work, what are the most common errors that result and which factors most affect the performance of technicians in these environments, which are characteristically complex. From this study, it is intended to determine the contribution of fatigue (physical and mental) and work organization to the occurrence of errors and the resulting risks regarding safety conditions of the maintenance workers themselves and, indirectly, of aircraft passengers. The training aspects and it importance and impact on stress induction in aircraft maintenance technicians are also addressed. Finally, it will also be analyzed to what extent vulnerability to fatigue and stress presents significant differences as a function of: (1) Seniority in the job: how it affects technicians? (2) Age: how it affects technicians? In order to answer the research questions and look for the existence of fatigue symptoms among Aircraft Maintenance Technicians (AMT), an individual and anonymous questionnaire was made available via the Internet, both for each subject and for the company where the AMT works. 15 companies that provide aircraft maintenance services in mainland Portugal were approached. The questionnaire had 55 responses, which were the basis of the work presented.

ABSTRACTS The abnormal incident happened in last few years in the nuclear power plant of Taiwan power company had been major report subject of the press, accumulated incident happened in previous years, there was phenomena of reoccurrence in several cases. We discuss the cause subject to these phenomena are main defect of the existing human prevention strategy. The cause of these defect was due to the deficiency or incorrect of technical recognition of the personnel work under uncertain situation. This study subject to the limited learning resulting from deficiency of existing prevention strategy and try to seek a reasonable resolution based on the view of organization learning. First we discuss according to the characteristic of existing prevention strategy and its defect, understand and categorize respectively to the assumption of the key factors of each existing prevention strategy, and analyze the effective characteristic of each model of the resolution of reoccurrence provided by organization learning one by one, finally raise the feasible increment effect subject to all human error prevention strategy respectively according to the characteristic of these model, these are the implication of the organizational learning in prevention strategy of human error. Proving by the case example, this consequent is feasible in practice application, and found that a effective prevention strategy in addition to characteristic of synthesis, it possess mechanism of unfreezing, change, freezing as well. The purpose of the existence of these mechanism in the organization learning which serve as human error prevention strategy are no more than maintaining the weltanschauung (World View) of the mental model of the action client and the organization, response to the environment effectively and correctly, and prevent the reoccurrence of the human error.
