In this paper, we propose a method to evaluate the reliability of the engineering systems using the fuzzy soft sets. When the reliability of components of the engineering systems must be expressed as multiple factors rather than a single value, it may be difficult to applying the conventional fuzzy sets to get the reliability for the components of engineering system. A way to solve this problem is the fuzzy soft sets. The fuzzy soft sets are a kind of the fuzzy sets that has been expanded so that belongingness degree of the elements of a soft set can be expressed as the fuzzy sets. When evaluating reliability using the fuzzy soft sets, the components that require multiple reliability values are expressed as elements of the universal set of the fuzzy soft sets, and the reliability for the components that require multiple reliability values are expressed as elements of the parameter set of the fuzzy soft set. The multiple reliability of components expressed as elements of the parameter set of the fuzzy soft set is calculated using the fuzzy set operations, and it is possible to evaluate the reliability of the entire engineering system based on the results of these operations. The method can be applied to the engineering systems and the multi-criteria decision-making systems that have components that require expressing multiple reliability. |
