We study a reliability system subject to shocks generated by a renewal point process. When a shock occurs, components fail independently of each other with equal probabilities that are random numbers drawn from a distribution that may differ from shock to shock. We first consider the case of a parallel system and derive closed expressions for the Laplace-Stieltjes transform and the expectation of the time to system failure and for its density in the case that the distribution function of the renewal process possesses a density. We then treat a more general system structure, which has some very important special cases, such as k-out-of-n:F systems, and derive analogous formulae.

The fundamental motivation for enterprises to build a standard system is to meet the subjective needs of the unique use nature of standards, such as benchmarking and criteria, from input to output in the baseline relationship of all their business processes. How to guess the credibility and value of the standard system requires collaborative and mature processes to mediate cognition. Firstly, this paper clarifies the philosophical relationship between standard system construction and process management by using the general system structure theory. Secondly, it systematically summarizes the interaction mechanism between the two from the perspective of methodology. Finally, it designs a conceptual model with the "human regulation" composite system as the core and the coupling between standard system construction and the outer edge of process management, and combed the three mechanism characteristics that affect the fit of the coupling model. In order to provide a new integration idea for enterprise standardization management and process management to jointly realize the optimal value utility.

The paper treats the problem of nests of interpreters i.e. multiple levels of interpretation of programs. The goal of the paper is to expose a control structure which models the important characteristics of such nests. Using a comparison with the Burroughs B6700 philosophy, a more general system model is introduced. There are two major results - a new type of control structure, and the conclusion that generalized nests perforce require retained environments.

Abstract. It is proved the importance of environmental management to ensure sustainable development of the port. Based on the study of academic literature, the factors of external and internal environment that determine the need for the development of environmental management are identified. A generalized model of the environmental management system is proposed and the need to introduce a rational management system at all levels of port management is emphasized. It is emphasized that the problem of developing a system of ecological and economic model of management and decision making requires the use of theory and methods of modern information technology, as well as methods of adaptive and intelligent management of port processes in real time based on a set of technological and economic and environmental criteria. It is offered the general principle of formation of the combined criteria of management on all levels of hierarchy according to decomposition of management system structure of a production function and at the account of both economic and ecological parameters. A system-wide generalized technological, economic and environmental criterion for management and decision-making has been developed, which includes both qualitative and quantitative characteristics of services and environmental parameters of pollutants. For all technological and transport processes the local control criteria corresponding to the general system criterion on observations of technological and ecological parameters are received. Variants of criteria of operative management of operational function of port are developed. It is emphasized that the specific choice of quality criteria is determined by many factors, such as the specifics of the problem, the nature and complexity of the object, the simplicity and feasibility of the proposed algorithms. Relevant principles are given for the selection of the appropriate criterion. The concept of ecological management of port’s operational function is formulated. Keywords: environmental management, environmental criteria, seaport, management system, management principles. JEL Classification M11 Formulas: 29; fig.: 2; tabl.: 0; bibl.: 24.

This paper focuses on the reliability analysis of [Formula: see text]-out-of-[Formula: see text] systems which are designed to perform a given mission consisting of several distinct phases. As the phases of the mission change, the reliability characteristics of the system and the system structure vary accordingly. The phase transition probabilities, phase durations, and component failure rates are dependent on the number of operating components. Moreover, the system is allowed to have cold, warm, or hot standby components. We propose computationally tractable methods to compute the system reliability, mean time to failure, and long-run availability for such a general system structure. We also provide a numerical analysis to show the applicability and the empirical computational complexity of the proposed methods.

To solve the problem of reduction of suspension force of permanent magnet system with variable magnetic flux path control, according to the structure of the system, suspension principle of the permanent magnet system with variable magnetic flux path control and the generation principle of the load torque, the influence of the mechanical structure of the system on the suspension force is analyzed by changing part of parameters of the system structure. The results show that the existence of magnetic isolation plate is the main reason for the decrease of suspension force, the permanent magnet ring can be thickened to 11.91 mm, the annular gap can be reduced to 1 mm, thickness of the “F” shaped magnetizer can be increased to 9 mm to increase the suspension force.

Imagination Sampling is the usage of a person as an oracle for generating or improving machine learning models. Previous work demonstrated a general system for using Imagination Sampling for obtaining multibox models. Here, the possibility of importing such models as the starting point for further automatic enhancement is explored.
