Abstract :
This study describes a new approach, i.e., the intuitionistic fuzzy success index method, for human reliability estimation using intuitionistic fuzzy sets. In our study, two offshore platform muster scenarios, i.e., “man overboard” and “gas release,” were considered as an assessing and a reference task, respectively. Herein, we aggregated the weightings and ratings of various performance shaping factors concerned with “man overboard” to obtain the intuitionistic fuzzy success index (IFSI) of the assessing task. Thereafter, we considered the pooled discrete intuitionistic fuzzy subset of the IFSI as the causal event and the known human reliability as the resultant event. Using this, we generate an intuitionistic fuzzy relation between the two events of the concerned task. The composition of the discrete intuitionistic fuzzy subset of the IFSI and the intuitionistic fuzzy relation gave the human reliability in the assessing task “man overboard.”
