Mission failure evolution is a unique aspect of complex human-machine system (CHMS), which contains failure regularity and directs emergent reconfiguration measures. Oriented to all varieties of system components, an analysis of how the parts are connected and contribute to CHMS failure is necessary. Prior work paid more attention to system design with the law of system normal operation, where a single...
Reliability design is in order to satisfy the reliability requirements with minimum cost. Similar to functional design, reliability design will face decision-making of multiple schemes. A new method for evaluation of reliability design from the standpoint of scheme implementation complexity (the cost of the design execution) based on information axiom is proposed in this paper. Comprehensive assessment...
Reliability has been greater concerned in recent years and allocating proper reliability value to each component of a complex system as an optimization process to reduce cost and rise productivity is very important. This paper presents a reliability allocation method based on Bayesian networks (BNs). In this paper, the approach are presented in two main aspects: modelling aspect and analysis aspect...
Traditional failure analysis results are mostly in text/graphics/tabular form, which brings challenges to intuitional and quick reliability design evaluation, and makes it difficult to recognize the complex interrelationships of failures. A 3-D modelbased failure model was proposed. Two types of failure visualization method oriented component and assembly are provided respectively. For a component,...
Fault tree analysis is very important in the reliability design and analysis program of a product. However, the traditional fault tree construction method is difficult to implement since it requires high capability of the modelers and a long period, furthermore the process is complicated. Compared with this, the Go model is easy to build due to its similarity with the principle diagram of the system...
In this paper, to completely meet the requirements of reliability design in the product designing, an axiom-based reliability design approach is proposed. In light of the axiomatic design principles, products are designed preliminarily to establish their functional requirements, so that according to these, functions preserving requirements are augmented, which constitute a functional requirement preserving...
This paper aims at sharing and reusing the reliability design knowledge of board-level electronic product (BLEP). The related concepts need to be compressed consistently in order to provide a common understanding of the reliability design knowledge, and a common recognition of the concept should be identified. Then based on this, all kinds of reliability design knowledge will be represented. In this...
The empirical data of product reliability design are often vague, comprehensive and incomplete. Information retrieval for reliability design depends on mining the knowledge applied to specific designing from mass empirical data. At the same time, designers are often lack of the judgments to accept or reject the reasoning results of reliability design knowledge. For these two issues, this paper presents...
