Aiming at hardware product’s reliability step change during the phase switch process, this study analyzes the factors that affect the reliability step change from the structural and nonstructural factors of the manufacturing system. The evaluation index system and evaluation model of reliability step change based on catastrophe theory are establish...
With an aim to overcome low efficiency and improve the performance of fuzzy clustering, two novel fuzzy clustering algorithms based on improved self-adaptive cellular genetic algorithm (IDCGA) are proposed in this paper. The new dynamic crossover and entropy-based two-combination mutation operations are constructed to prevent the convergence of the...
With an aim to minimize the difference of use reliability of air conditioning (AC) systems in different regions, a clustering method for classifying regions based on factors of the reliability of AC systems is proposed. This study establishes a comprehensive evaluation model of regional clustering on the basis of analysis and investigation about th...

... 'ese two methods have long been widely used in other fields. In order to overcome the low efficiency of fuzzy clustering and improve its performance, Jie et al. have proposed two fuzzy clustering algorithms based on an improved adaptive cytogenetic algorithm (GA) [6]. Dong et al. have proposed a fuzzy clustering method based on multiobjective GA [7]. ...
... Warranty policy decisions should consider not only the key marketing factors, including selling price, warranty period, and postwarranty commitments, but also the inherent technical factors, such as product quality and reliability [2], [3]. However, the use reliability of products distributed in different geographical regions exhibits a significant difference because the working conditions and service time of products vary from region to region [4]. Therefore, developing a scientific and reasonable warranty strategy from the perspective of product use reliability is meaningful. ...
