Distribution Of Components

In an actual industrial or military operations environment, a multi-state system (MSS) consisting of multi-state components often needs to perform multiple missions in succession. To improve the probability of the system successfully completing the next mission, all the maintenance activities need to be performed during maintenance breaks between any two consecutive missions under limited maintenance resources. In such case, selective maintenance is a widely used maintenance policy. As a typical discrete mathematics problem, selective maintenance has received widespread attention. In this work, a selective maintenance model considering human reliability for multi-component systems is investigated. Each maintenance worker can be in one of multiple discrete working levels due to their human error probability (HEP). The state of components after maintenance is assumed to be random and follow an identified probability distribution. To solve the problem, this paper proposes a human reliability model and a method to determine the state distribution of components after maintenance. The objective of selective maintenance scheduling is to find the maintenance action with the optimal reliability for each component in a maintenance break subject to constraints of time and cost. In place of an enumerative method, a genetic algorithm (GA) is employed to solve the complicated optimization problem taking human reliability into account. The results show the importance of considering human reliability in selective maintenance scheduling for an MSS.

Human Error Probability

Safety is the eternal theme in shipping industry. Research shows that human error is the main reason of maritime accidents. Therefore, it is very necessary to research marine human errors, to discuss the contexts which caused human errors and how the contexts effect human behavior. Based on the detailed investigation of human errors in collision avoidance behavior which is the most key mission in navigation and the Performance Shaping Factors (PSFs), human reliability of mariners in collision avoidance was analyzed by using the integration of APJE and SLIM. Result shows that this combined method is effective and can be used for the research of maritime human reliability.

The Law

The rule of law is a fundamental principle of the legal sphere. Its assertion in the state institutions of democratic countries is an outstanding achievement of mankind. The implementation of this principle is the basis of civil society and civil liberties. The rule of law is the supremacy of law in society. The rule of law provides for its implementation in law-making and law enforcement activities. The manifestation of the rule of law is that the law is not limited to legislation as one of its forms, but also includes other social regulators (norms of morality, traditions, customs, etc., which are legitimized by society). All these elements of law are united by a quality that corresponds to ideology of justice – the idea of law, which is largely implemented in the Constitution of Ukraine. The first problem for the implementation of the principle of law in Ukraine is that this principle has not yet received the proper normative consolidation and official interpretation. The second problem is its extension to socio-economic rights and social benefits. The third problem is the insufficient level of legality in our state. The aim of the paper is to establish the peculiarities of implementation of the principle of the rule of law at the present stage of development of scientific and technological progress. The task of the paper is to investigate the peculiarities of implementation of the rule of law in the application of information and analytical technologies of system engineering in the legal sphere. In accordance with the experience of using information-analytical technologies of system engineering in the legal sphere, the paper outlines the peculiarities of implementation of the principle of the rule of law in the system analysis and modeling of the state system of Ukraine. The principle of the rule of law must be taken into account in such modeling as "governing circumstance". That is the resource according to which the state system of Ukraine functions. Our preliminary works give grounds to assert that information and analytical technologies of systems engineering are also a promising methodological tool for studying the principles of state building. The principle of the rule of law is the cornerstone of building a democratic state governed by the rule of law in Ukraine. Three years ago, scholars moved away from identifying the rule of law with the law-creating instruments.

Almost All

Almost all philosophy about the state system has concentrated on the authorities. Any function of the state can be represented as a superposition of the functions of violence / coercion. Ultimately, the state appears to be a kind of plurality of subjects with a definite crater power / coercion / violence operation on it. The algebra of trust on the multiplicity of owners of themselves, endowed with free future, is each of them is only a part of nature, еру carrier of the part of the general human culture, and for their completeness, they have and understand the need for the Other. This is the philosophy of solving political, environmental, and climate challenges not through violent / voluntaristic methods, but by the recognition of sovereign rights and the search for ways to achieve sustainable development. Any cracy / power / coercion / violence must be separated from the models of society, the state. Public agreement is not an agreement with the abstract notion of the state, but an agreement with definite elected people who have gained the trust of those to whom they temporarily render their services. Contract is temporary, limited by period, with obligatory full responsibility of the parties. Scientific novelty. For more than two thousand years, long before Aristotle and Plato, European philosophical thought, reflecting on the structure of society, wanders in the labyrinths of kratia. Modern achievements of mathematics provide an opportunity to build ideal political objects, and a direct product of material and ideal government building. (Example of a trust algebra [4].)

Human Rights Violation

The respect of human rights in a society determines the destination of that society or state. It is the level of satisfaction of citizens of a country which convinces them to work for the growth and progress of that state or society. The people of FATA are living under a draconian law which is known as Frontier Crime Regulations (FCR). There is agrave human rights violation of the people of FATA under this law. Freedom of speech, freedom of expression etc. are hampered by the FCR and the common people live under a threat of collective punishment as well. Moreover, due to military operations against the militants in the area, millions of people from FATA have been displaced. At times, there are grave violations of human rights of the displaced persons as well. This paper will explore the state of human rights in FATA in general and evaluates its impact on the Federation of Pakistan. The paper evaluates different instances of human rights violation in various agencies of FATA and their root causes as well.
