Reliability of Safety Instrument System Based on Markov Model and D-S Evidence Theory

Abstract:

The quantitative assessment of reliability of Safety Instrument System (SIS) is very important in upgrading its security. The calculation of reliability of SIS based on Markov model has been largely used by scholars and research institutions. Assume that each state has a fixed value in the Markov Model. While in practical application, each state changes from the best status to the second-best status. This thesis will introduce D-S Evidence Theory into Markov Model, fully using SIS Reliability Function and Plausibility Function to reflect the changes of each state and assess its safety more exactly and precisely.
