چکیده
Fault tree analysis is a well-known technique in reliability engineering and risk assessment, which supports decision-making processes the management of complex systems. Traditionally, fault (FT) models are built manually together with domain experts, considered time-consuming process prone to human errors. With Industry 4.0, there an increasing availability inspection monitoring data, making techniques that enable knowledge extraction from large data sets relevant. Thus, our goal this work propose data-driven approach infer efficient FT structures achieve complete representation failure mechanisms contained set without intervention. Our algorithm, FT-MOEA, based on multi-objective evolutionary algorithms, enables simultaneous optimization different relevant metrics such as size, error computed Minimal Cut Sets. results show that, for six case studies literature, successfully achieved automatic, efficient, consistent inference associated models. We also present parametric tests algorithm conditions influence its performance, well overview methods used automatically

Evolutionary Multi-Objective Algorithms
The versatility that genetic algorithm (GA) has proved to have for solving different problems, has make it the first choice of researchers to deal with new challenges. Currently, GAs are the most well known evolutionary algorithms, because their intuitive principle of operation and their relatively simple implementation; besides they have the ability to reflect the philosophy of evolutionary co...
متن کاملMulti-Objective Evolutionary Algorithms
Real world optimization problems are often too complex to be solved through analytical means. Evolutionary algorithms, a class of algorithms that borrow paradigms from nature, are particularly well suited to address such problems. These algorithms are stochastic methods of optimization that have become immensely popular recently, because they are derivative-free methods, are not as prone to get...
متن کاملAutomatic Design of Evolutionary Algorithms for Multi-Objective Combinatorial Optimization
Multi-objective evolutionary algorithms (MOEAs) have been the subject of a large research effort over the past two decades. Traditionally, these MOEAs have been seen as monolithic units, and their study was focused on comparing them as blackboxes. More recently, a component-wise view of MOEAs has emerged, with flexible frameworks combining algorithmic components from different MOEAs. The number...
متن کاملParallel Multi-objective Evolutionary Algorithms
This paper describes a general overview of parallel multi-objective evolutionary algorithms (MOEA) from the design and the implementation point of views. A unified taxonomy using three hierarchical parallel models is proposed. Different parallel architectures are considered. The performance evaluation issue of parallel MOEA is also discussed.
