Reliability Design

The mechanical reliability design method is a common method, and it is the most direct and effective method to carry out the mechanical reliability design at present. The reliability optimization design is an effective optimization design method which is developed in combination with the reliability design theory on the basis of the conventional optimization design. Taking the antifriction bearing as an example, this paper systematically expounds all kinds of mechanical reliability design methods. Through comprehensive analysis of various factors that affect the reliability of colliery machine, the index system of colliery machine reliability evaluation is established. Because of the complexity and diversity of the use of colliery machine in the evaluation system, and the fuzziness of human thinking, it is difficult to give the deterministic evaluation information in numerical form, so this paper also analyzes the design method of colliery mechanical reliability, and puts forward an interval fuzzy evaluation method for colliery mechanical reliability evaluation to avoid overload operation of colliery machine and ensure safety production and safety of workers. The simulation results show that the inherent law of reliability is effectively characterized by this method, and it provides a evidence for security produce and scientific decision-making of colliery mechine.

This paper proposes new approaches to a kind of redundant design method to control computers based on CPCI bus, which discusses the choice of redundancy model and system principle. The reliability design is the key element of the system design, as the requirement for high reliability of general users to control computer system. It introduces in detail the interlocking theory and design method, the switching control circuit design and the data sharing model. In the end we conduct reliability analysis on the redundant control computer system from the aspect of the mean time between failures (MTBF) and availability. The redundant design approach effectively improves the reliability of the control computer system, and test and application prove that the control computer can meet the requirement for reliability.

Purpose The purpose of this paper is to develop an integrated approach for a green product cradle-to-cradle (C2C) fuzzy recycling production planning model. Design/methodology/approach This paper applies the failure mode and effects analysis technique and Taguchi experimental design method, develops a green product C2C performance evaluation system that considers the fuzzy impacts of environmental laws and regulations, green goodwill, and environmental efficiency of targeting countries, and decides both the optimal green production plan and estimated optimal life cycles. Findings This study compares the different degree of maturity in environmental regulations, and various recycling situations are simulated to demonstrate the successful applicability of the proposed model as well as the incentive policy for Taiwan, the USA and Bangladesh. Originality/value Previous studies failed both to develop a holistic recycling production plan which is able to consider both the optimal combination of recycled components used and final green products produced with the maximum total resultant sales profit and to consider the potential failure phenomenon of recycled components adopted in the final product. Furthermore, most prior studies ignored the influence of environmental law, goodwill of the product and the efficiency of recycling mechanism of the community.

The design of engineering systems involves the design of dependent subsystems and the integration of these into a whole. A typical system has the characteristics of being multileveled, multidimensional, and multidisciplined in nature. It is this complexity which causes problems for the designer in making well-founded decisions. A decision support technique has been developed which offers a structured facility for the design of the subsystems and for the modeling of the interaction which is present between subsystems. The method, employing optimization procedures, allows all aspects of the system design to be considered concurrently, to produce the "best" solution, as defined by the specifications. This is in contrast to the traditional design method, which is iterative and cyclic in nature, involving sequential reevaluation and refinement. In this paper, the effectiveness and efficiency of the decision support problem approach is demonstrated using the hierarchical characteristics of a design for a barge. The barge problem, though basic in form, is comprehensive in concept and tutorial in nature. As a formulation for "system" optimization, it uses a computer-based method for solution and illustrates the virtues of a multilevel/multidisciplinary approach to design and decision-making. It also exhibits the same characteristics and provides valuable insight into the solution of the more complex problems encountered in practical ship design.

ABSTRACT Stabilizing pile is a widely used method to reduce the development of large-scale landslides. Optimizing the pile geometry is a great challenge in the design of stabilizing piles with the purpose of cost-effectiveness, especially for soil strength parameters with large uncertainty. The objective of this study is to propose a robust and efficient method of designing piles for landslide stabilization with the consideration of the safety of slope, uncertainty of soil parameters, and cost of stabilizing piles. A new response surface, which incorporates soil parameters and stabilizing force into a quadratic polynomial function, is first proposed. Unknown coefficients of the quadratic polynomial function are solved with a numerical method at typical sampling points. Based on the solved quadratic polynomial function, the mean and standard deviation of factor of safety (FOS) of the pile-stabilized slope as well as the signal-to-noise factor are then calculated in order to evaluate the design robustness. A framework based on the concept of robust geotechnical design is presented, and its feasibility is illustrated by two cases of soil slopes. The results indicate that the proposed robust geotechnical design method could be used to optimize the design of landslide-stabilizing piles.
