The diffusion of micro electro-mechanical systems (MEMS) technology applied to navigation systems is rapidly increasing, but currently, there is a lack of knowledge about the reliability of this typology of devices, representing a serious limitation to their use in aerospace vehicles and other fields with medium and high requirements. In this paper, a reliability testing procedure for inertial ...

Maintenance of a computer-based system accounts for a large proportion of the total system cost. However, no well-established techniques exist for assessing the maintainability of such a system. This paper presents a case study in assessing the maintainability of a large, software intensive system. The techniques we used are described, and their strengths and weaknesses discussed.

Abstract The post-construction phase represents a critical milestone in the project lifecycle. This is because design errors and omissions as well construction defects are examined during this phase. traditional procurement approaches that commonly adopted projects separate from construction, which inhibits contractors, suppliers other parties providing team with constructive comments feedback ...

This paper discusses the Reliability, Availability, Maintainability, and Safety (RAMS) of an electrical power supply system in a large European hospital. The primary approach is based on fuzzy logic Petri nets, using CPNTools software to simulate determine most important modules according Automatic Transfer Switch. Fuzzy Inference System used analyze assess reliability value. stochastic versus ...

Optimizing incremental view maintenance is an important problem in data warehousing. One popular technique, view self-maintenance, proposed computing the required view updates without using the underlying base relations. Traditionally, self-maintainability of a view is determined solely based on the view definition, independent of the state of the base relations. However, this “compile-time” ap...

The paper presents a multi-factor decision-making approach for prioritizing failure modes 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 (failure occurrence, non-detection, maintainability...
