There are 3 approaches in robust design, system design, parameter design and tolerance design. All three approaches can be used to improve product reliability in different aspects. Robust design method and reliability engineering should be combined to enhance the overall product quality and reliability.展开更多

A comparison between such a signaling mechanism and a ＂full fair value disclosure＂ is firstly carried out, highlighting variables affecting the efficiency and the effectiveness of both information strategies. Then, recovering the traditional distinction between ＂protective disclosure＂ （hard information） and ＂informative disclosure＂ （soft information）, this paper demonstrates how the former could significantly increase the positive effects associated to an employment of an independent valuer, reaching some conclusions useful to the standard setting process.展开更多

文摘This paper discusses many fundamental relationships between robust design methods and reliability improvement. There are 3 approaches in robust design, system design, parameter design and tolerance design. All three approaches can be used to improve product reliability in different aspects. Robust design method and reliability engineering should be combined to enhance the overall product quality and reliability.

A comparison between such a signaling mechanism and a ＂full fair value disclosure＂ is firstly carried out, highlighting variables affecting the efficiency and the effectiveness of both information strategies.

文摘The evaluation of reliability for structural system is important in engineering practices.In this paper,by combining the design point method,JC method,interval analysis theory,and increment load method,we propose a new interval design point method for the reliability of structural systems in which the distribution parameters of random variables are described as interval variables.The proposed method may provide exact probabilistic interval reliability of structures whose random variables can have either a normal or abnormal distribution form.At last,we show the feasibility of the proposed approach through a typical example.
