Uncertainty analysis is incorporated at the production scheduling stage to improve the probability of performing the resulting schedule. This probability will depend on forecasts of equipment failure. The effects of equipment failure on the production schedule are minimised by means of reliability indexes for each plant unit. Avoiding the use of equipment with low reliability

The Consequences of Equipment Failure - Facility ...

14/10/2013  The Consequences of Equipment Failure. If a manager decides to defer needed repairs or replacement, what is the impact of continued failures? In some instances, there is the potential for environmental issues or violations. Safety and health also need to be considered. This includes service disruption, staff comfort, and systems, as well.

[PDF] MODELLING OF EQUIPMENT FAILURE RATE ACCOUNTING

A fuzzy model for failure rate with the consideration of the effects of uncertain factors in distribution reliability evaluation is presented. The possibility and credibility distribution analyzed on the basis of sample datum are used for quantifying effects of the uncertainty done to failure rate. Mathematically, the failure rate can be obtained in the interval integration.
