Analysing equipment failure rates
International Journal of Quality & Reliability Management, 1996Reports on recent research at NORWEB, concerned with rationalizing the company′s equipment replacement policies which has focused on the failure rates of 11kV/415V pole mounted transformers. Results confirm that the Gumbel distribution provides a much more convincing statistical representation for these fault data than the usual Weibull option.

Journal of the Operations Research Society of America, 1953
This paper had its origin in consideration of the work reported on by D. M. Boodman [Boodman, D. M. 1953. The reliability of airborne radar equipment. Jour. Op. Res. Soc. America 1 (February) 39–45.]. The purpose is to examine some of the implications arising from the assumption that a piece of complex equipment fails when, and only when, one of its ...

Equipment failure rate updating—Bayesian estimation
Journal of Hazardous Materials, 2008The paper presents a Bayes' method for augmenting generic equipment failure data with a prior distribution - predicated on the evidence, e.g., plant data - resulting in a posterior distribution. The depth of the evidence is significant in shaping the characteristics of the posterior distribution.

Failures Monitoring in Refrigeration Equipment
2018The refrigerators are the responsible to assure the temperature and humidity conditions for perishable products stored in it. In this sense, it is necessary to guarantee its good performance at all times in order to preserve the products. In this article We propose a failures monitoring system for refrigeration equipment using Internet of Things (IoT ...

The Failure Law of Complex Equipment
Journal of the Society for Industrial and Applied Mathematics, 1960below which is slightly more general than Palm’s, and a somewhat different approach is adopted. The viewpoint is more particularly taken here that the problem is in the nature of a probabilistic limit theorem, and that accordingly the addition of independent variables and the central limit theorem is a useful prototype.

Equipment failure control model based on failure life cycle
2012 International Conference on Quality, Reliability, Risk, Maintenance, and Safety Engineering, 2012For complex equipment, there are always some rather deep-rooted inherent causes lead to function failure on some crucial components with serious effect, traditional maintenance can not remove or shield that effectively, and the similar failures happen again soon after.

Equipment Management through Operational Failure Costs
Journal of Construction Engineering and Management, 1994This paper defines operational failure costs (OFC’s), presents a method for their development, and examines their usefulness as a means of equipment management. It considers variables related to the projected use of the equipment in the context of the production team and the construction site as a whole as well as the importance of each piece of ...
