Rural electrification, especially in the developing countries, is one of the major applications of solar PV based energy systems. The choice of an appropriate PV module and battery technology is very crucial for the success of a product or business model. In the context of PV for off grid rural applications, the choice of technology is not only determined by technological parameters, but also by various...
The effective assessment of organizational reliability, maintainability and supportability (RMS) engineering capability has an important significance to improving organizational RMS work level. For the problem of organizational RMS engineering capability assessment being complex, and many indexes being fuzzy and difficult to be defined the value and weight, a method based on fuzzy analytic hierarchy...
In this paper, a multi factor decision making approach is presented for prioritizing failures causes for the digester of pulping system of a paper mill as an alternative to traditional approach of failure mode and effect analysis (FMEA). The approach is based on the `technique for order preference by similarity to ideal solution' (TOPSIS). The priority ranking is formulated on the basis of six parameters...
The following reliability indexes are calculated based on the observed one year and a half maintenance records for two gearbox shell production lines after 10 years of running: F(t), R(t), MTBF, MTTR, K, A and C. By contrasting the dynamic indexes of these 2 lines, we find out that the reliability of flexible line is lower than that of the rigid line. Furthermore, we build a fuzzy comprehensive model...
