Costs as well as safety performance are usually taken into account in safety instrumented system design. Modeling a SIS is time consuming and fallible and altering a SIS design may lead to recreating the model, so it's difficult to compare one design with others effectively and quickly. Markov model and its automatic creation for SIS are described in this paper, followed by the analysis of SIS life...
Availability is an important performance index for wind turbines. To predict wind turbine availability, failure rate and repair rate have to be known. There are some sources of wind turbine failure data that can be used to estimate parameters of the failure rate function and the repair rate. With repair rate assumed to be constant, this paper first presents maximum likelihood estimates for failure...
