A thorough analysis of data on aircraft lifecycle revealed inadequacy of current lifecycle management methods in the face of increased complexity of the Internet-based global market. A new method for managing lifecycle has been developed by authors and their teams using concepts and principles of the emerging complexity science with the aim of reducing lead times and costs. Centralised control has been replaced with distributed decision-making empowering all lifecycle stakeholders. The solution described in this paper is the first of its kind and it represents a genuine advance in knowledge, which leads to considerable reduction in design/production lead times and decrease in the lifecycle cost. The method has been validated in a variety of applications. © 2016 WIT Press.

The main objective of this paper is to argue that the scientific approach to reliability and safety is the only way forward for the reliability community if accurate predictions regarding occurrences of negative functionability events are to be made and subsequently verified during the operational processes of the future man made, managed and maintained systems. For that to happen, a scientific understanding of the mechanisms that cause occurrences of functionability events of the surrounding natural environment are required. Then and only then, can accurate and meaningful reliability and safety predictions become possible, enabling the ultimate goal of reducing the probability of failure event occurrences during the life of man made, managed and maintained systems. This paper focuses on the scientific understandings of the relevant cosmic radiation on aviation reliability and safety.

Mirce Mechanics is a scientific theory of the motion of in-service systems through Mirce Spacetime that enables prediction of the work done by them to be made by using Mirce Equations. However, practical applications of Mirce Mechanics are possible only, when the physical mechanisms that generate the motion of systems through positive and negative states are understood. The mechanism of ice building on an aircraft on the ground is addressed in this paper, as a cause of occurrence of a negative in-service event. It is generated under certain environmental conditions when precipitation falling onto the aircraft freezes, mainly on upper surfaces of the wing and tail, endangering the flight safety. This type of negative events is followed by de-icing process of the aircraft at the airport, as a physical mechanism that causes the transition of an aircraft from the negative to the positive in-service state. Several de-icing methods are presented in this paper together with the analysis of their impacts on aircraft and environment.

The second Axiom of Mirce Mechanics, states, "The probability of faulty execution of any maintenance task is greater than zero". Analysis of maintenance processes clearly shows that ineffective communication between system designers and maintenance personnel, through maintenance documentation, is a well-recognised contributor to the occurrence of faulty maintenance task, which in turn could have a significant impact on reliability, availability, safety, cost and effectiveness of technical systems. This paper addresses the lack of understanding of maintenance manuals, written in English, by 80% of the global maintenance personnel whose native language is not English. The majority of them have knowledge of English that is rather limited and are easily confused by complex sentence structures and by the number of meanings and synonyms that English words may have. Significant improvements in the direction of effective communication have been achieved by the creation and use of Simplified Technical English, the benefit of which is presented in this paper.

Purpose - The purpose of this paper is to develop a science-based formulation of quality of maintenance processes. Design/methodology/approach - The paper takes the form of scientific analysis of the faulty maintenance tasks to determine the pattern of phenomena and to understand the nature of causing mechanisms. Findings - Faulty maintenance tasks are found to exist in statistical analysis of the tens of thousands of maintenance tasks in defence, aerospace, transportation (including Formula 1 Grand Prix racing), communication and other industries, which has led to the formulation of the probabilistic axiom of the quality of maintenance. Practical implications - This axiom has a profound impact on the properties of any maintainable system, such as reliability, availability, safety, cost, effectiveness and many others, on the one hand, and associated processes such as manufacturing, operation, logistics support, on the other. Originality/value - The paper presents the formulation of the second axiom of Mirce Mechanics, which is related to the quality of the maintenance processes and a new classification of quality-based maintenance tasks. © 2012 Emerald Group Publishing Limited.

Birds represent a serious, but often misunderstood, threat to aircraft. Most bird strikes do not result in any aircraft damage, but some bird strikes have led to serious accidents involving aircraft of every size. According to Bird strike Committee USA, bird and other wildlife strikes to aircraft result in over $600 million in damage to U.S. civil and military aviation each year. The lives of the crew and passengers are also at risk. Since 1988, over 200 people have been killed worldwide as a result of encounters with birds and other wildlife. Thus, this paper addresses bird strike from MIRCE Mechanics point of view, which means that it is considered as a mechanism that generates a functionability event which causes the motion of a system from positive to negative functionability state. The paper provides vital information about the physical properties of most common birds that are required for predictions of their impacts on aircrafts, at the design stages as a scientific method for the evaluation of alternatives.

Reliability Theory, since it's beginnings in 1950s, has been based on mathematical theorems rather then on scientific theories. Massive attempts where made to further applications of the existing mathematical and statistical methods and analysis without attempts for understanding failure mechanics. Then, in 1980s, practicing reliability engineers and analysts, who have neither ability nor need to understand the mathematics, turned to what they have had, which is enormous practical experience of the observed failure modes of existing systems. Thus, a large number of practical reliability methods have been developed and used, all of which were based on the failure mode, effect and criticality analysis, but still without understanding and addressing failure mechanics. Consequently, during the last 50 years the Reliability Theory made very little progress, a part from a few exceptions, in the direction of becoming the science, in terms of making accurate predictions that could be confirmed with practical observations. The reason is very simple; neither statistics, which does not study causes of statistical behaviour, nor engineers whose applied methods were focused on meeting contractual and legal requirements, were able to provide a fertile ground for the development of reliability. © 2010 IEEE.

If you watch a glacier from a distance, and see the big rocks fallings into the sea, and the way the ice moves, and so forth, it is not really essential to remember that it is made out of little hexagonal ice crystals. Yet if understood well enough the motion of the glacier is in fact a consequence of the character of the hexagonal ice crystals. But it takes quite a while to understand all the behaviour of the glacier (in fact nobody knows enough about ice yet, no matter how much they've studied crystal). However, the hope is that if we do understand the ice crystal we shall ultimately understand the glacier.
